Description

布料及複合薄片及研磨布及擦拭製品Fabrics and composite sheets and abrasive cloths and wipes

本發明係關於含有極細纖維之布料及使用該布料之複合薄片，以及使用該等布料或複合薄片組成之研磨布及擦拭製品。The present invention relates to a cloth containing ultrafine fibers, a composite sheet using the same, and a polishing cloth and a wiping article comprising the cloth or composite sheet.

過去，含有極細纖維之布料已廣泛用於研磨布及擦拭製品等領域中。In the past, fabrics containing very fine fibers have been widely used in the fields of polishing cloths and wiping products.

研磨布大部分用於在記錄光碟之基板表面上形成細微之溝槽(例如，參照專利文獻2、專利文獻3、專利文獻4)。由於該溝槽為均勻且細微之程度，可縮小記錄光碟與磁頭之距離，因此可使磁碟等高容量化及高記憶密度化。Most of the polishing cloth is used to form fine grooves on the surface of the substrate on which the optical disk is recorded (for example, refer to Patent Document 2, Patent Document 3, and Patent Document 4). Since the groove is uniform and minute, the distance between the recording disk and the magnetic head can be reduced, so that the disk can be increased in capacity and the memory density can be increased.

另外，擦拭布或擦拭帶等擦拭製品可用於清潔用途、眼鏡擦拭用途、IC或半導體等產業用途、鏡片擦拭用途等(參照例如專利文獻1、專利文獻5、專利文獻6、專利文獻7、專利文獻8)。該擦拭製品已知有含有天然纖維之擦拭製品、由不織布構成之擦拭製品、使用聚酯纖絲之擦拭製品等。In addition, a wiping product such as a wiping cloth or a wiping tape can be used for cleaning applications, glasses wiping applications, industrial applications such as ICs and semiconductors, lens wiping applications, and the like (see, for example, Patent Document 1, Patent Document 5, Patent Document 6, Patent Document 7, and Patent). Document 8). The wiping product is known as a wiping product containing natural fibers, a wiping product composed of a non-woven fabric, a wiping product using polyester filaments, or the like.

然而，含有天然纖維之擦拭製品會將細毛掉落在擦拭對象物表面上，而有產生灰塵之類之問題。另外，由不織布構成之擦拭製品會自不織布脫落之纖維掉落在擦拭對象物表面上，而有產生灰塵之類之問題。又，使用聚酯纖絲之擦拭製品通常由於聚酯中含有之消艷劑會掉落在擦拭對象物表面上，而有消艷劑本身成為塵埃之問題，或傷及擦拭對象物表面之問題。However, a wiping article containing natural fibers drops fine hair on the surface of the object to be wiped, and there is a problem such as generation of dust. Further, the wiping product composed of the non-woven fabric may fall on the surface of the wiping object from the non-woven fabric, and there is a problem that dust is generated. Moreover, the wiping product using the polyester filament usually has a problem that the deodorant contained in the polyester falls on the surface of the object to be wiped, and the deodorant itself becomes a problem of dust or damages the surface of the object to be wiped. .

依據本發明，係提供一種可降低被研磨物表面之缺陷(刮痕)發生率而可在被研磨物上形成細微溝槽之作為研磨布用布料使用，又，亦可用作擦拭性良好且灰塵少之擦拭製品用布料之布料，以及使用該布料之複合薄片，及使用該等之研磨布及擦拭製品。According to the present invention, there is provided a cloth for polishing cloth which can reduce the incidence of defects (scratches) on the surface of the object to be polished, and can form a fine groove on the object to be polished, and can also be used as a wiping property. A cloth with a cloth having a small amount of dust, a composite sheet using the cloth, and a polishing cloth and a wiping product using the cloth.

首先，本發明之布料中，重要的是聚酯多纖絲A其單纖維直徑(單纖維之直徑)在50~1500nm(較好為100~1000nm，更好為400~800nm，最好為520~800nm)之範圍內。該種單纖維直徑換算成單絲纖度時，相當於0.00002~0.022dtex。其中，當單纖維直徑未達50nm時不僅難以製造，且由於纖維強度降低而在實用上不佳。相反的，當單纖維直徑超過1500nm時，使用布料作為研磨布用布料時，無法在被研磨物上形成細微溝槽而不佳。又，當單纖維直徑超過1500nm之情況下，使用布料作為擦拭製品用布料時，無法獲得充分擦拭性而不佳。又，單纖維之剖面形狀為圓剖面以外之異型剖面時係以外接圓之直徑成為單纖維直徑。又，單纖維直徑可藉由以透過型電子顯微鏡對纖維之剖面照相而測定。First, in the cloth of the present invention, it is important that the polyester multifilament A has a single fiber diameter (the diameter of the single fiber) of 50 to 1500 nm (preferably 100 to 1000 nm, more preferably 400 to 800 nm, and most preferably 520). Within the range of ~800nm). When the single fiber diameter is converted into a single fiber fineness, it is equivalent to 0.00002 to 0.022 dtex. Among them, when the diameter of the single fiber is less than 50 nm, it is not only difficult to manufacture, but also practically poor due to a decrease in fiber strength. On the other hand, when a single fiber diameter exceeds 1500 nm, when a cloth is used as a cloth for a polishing cloth, it is not preferable to form a fine groove on the object to be polished. Further, when the diameter of the single fiber exceeds 1500 nm, when the cloth is used as the cloth for the wiping article, it is not preferable to obtain sufficient wiping property. Further, when the cross-sectional shape of the single fiber is a profiled cross section other than the circular cross section, the diameter of the circumscribed circle becomes the single fiber diameter. Further, the diameter of the single fiber can be measured by photographing the cross section of the fiber with a transmission electron microscope.

上述聚酯多纖絲A中，纖絲數並無特別限制，較好為1000以上(更好為2000~20000，最好為2000~10000)。又，聚酯多纖絲A之總纖度(單纖維纖度與纖絲數之乘積)以在5~200dtex之範圍內較佳。In the polyester multifilament A, the number of filaments is not particularly limited, but is preferably 1,000 or more (more preferably from 2,000 to 20,000, more preferably from 2,000 to 10,000). Further, the total fineness (the product of the single fiber fineness and the number of filaments) of the polyester multifilament A is preferably in the range of 5 to 200 dtex.

形成該種聚酯多纖絲A之聚合物重要的是消艷劑之含有率為聚酯重量對比0.5重量%以下(更好0.1重量%以下，最好0重量%)之聚酯。消艷劑多於聚酯重量對比0.5重量%而包含於聚酯中時，使用布料作為研磨布用布料之情況，使用研磨布研磨被研磨物時，容易在被研磨物表面上產生缺陷(刮痕)而不佳。又，消豔劑為多於聚酯重量對比0.5重量%而包含於聚酯中時，使用布料作為擦拭製品用布料時，包含於構成布料之纖維中之消豔劑粒子由於擦拭對象物與纖維之摩擦，而有掉落在對象物之表面上使消豔劑本身成為塵埃，進而在對象物上產生傷痕之情況。It is important to form a polymer of the polyester multifilament A as a polyester having a content of the deodorant of 0.5% by weight or less (more preferably 0.1% by weight or less, preferably 0% by weight) based on the weight of the polyester. When the amount of the deodorant is more than 0.5% by weight based on the weight of the polyester and is contained in the polyester, when the cloth is used as the cloth for the polishing cloth, when the object to be polished is ground using the polishing cloth, it is easy to cause defects on the surface of the object to be polished (scraping The mark is not good. Further, when the coloring agent is contained in the polyester in an amount of more than 0.5% by weight based on the weight of the polyester, when the cloth is used as the cloth for the wiping product, the particles of the deodorant particles contained in the fibers constituting the cloth are wiped by the object and the fiber. The friction is applied to the surface of the object to cause the deodorant itself to become dust, thereby causing a flaw on the object.

又，形成上述聚酯多纖絲A之聚酯種類較佳例示為聚對苯二甲酸乙二酯或聚對苯二甲酸丙二酯、聚對苯二甲酸丁二酯、使立體錯合聚乳酸、聚乳酸、第三種成分共聚合之聚酯等。另外，本發明之消豔劑為二氧化鈦時，二氧化鈦為無機微粒子之一種。該二氧化鈦之含量可藉由使用螢光X射線(例如，RIGAKU電機工業(股)製造之ZSX100e)之方法，或使用溶劑使聚酯溶解之方法而測定。Further, the polyester type forming the polyester multifilament A is preferably exemplified by polyethylene terephthalate or polytrimethylene terephthalate or polybutylene terephthalate to cause stereoscopic misfolding. A polyester in which lactic acid, polylactic acid, and a third component are copolymerized. Further, when the deodorant of the present invention is titanium dioxide, titanium dioxide is one of inorganic fine particles. The content of the titanium oxide can be determined by a method using fluorescent X-rays (for example, ZSX100e manufactured by RIGAKU Electric Industries Co., Ltd.) or a method of dissolving the polyester using a solvent.

又，上述聚合物中，可依據需要在不損及本發明目的之範圍內包含一種或兩種以上之陽離子染料可染劑、抗著色劑、熱安定劑，但較好不含無機微粒子。Further, in the above polymer, one or two or more kinds of cationic dye dyeable agents, anti-coloring agents, and heat stabilizers may be contained as needed within the range not impairing the object of the present invention, but preferably no inorganic fine particles are contained.

上述聚酯多纖絲A之纖維形態並無特別限制，例如對上述聚酯多纖絲A進行一般之空氣加工、假撚捲縮加工亦無妨。The fiber form of the polyester multifilament A is not particularly limited. For example, the polyester multifilament A may be subjected to general air processing or false twist crimping.

另一方面，聚酯多纖絲B重要的是其單纖維直徑為3μm以上(較好為3~30μm)之範圍內。當該單纖維直徑小於3μm時，由於布料之壓縮剛性小，因此使用布料作為研磨布用布料時，被研磨物表面容易產生缺陷(刮痕)而不佳，另外，當該單纖維直徑小於3μm時，使用布料作為擦拭製品用布料之情況下，布料表面成為平坦而損及擦拭性。其中，單纖維之剖面形狀為圓剖面以外之異型剖面時，以外接圓之直徑作為單纖維直徑。另外，單纖維直徑與上述相同，可藉由以透過型電子顯微鏡對纖維之剖面照相而測定。On the other hand, the polyester multifilament B is important in the range of a single fiber diameter of 3 μm or more (preferably 3 to 30 μm). When the diameter of the single fiber is less than 3 μm, since the compression rigidity of the cloth is small, when the cloth is used as the cloth for the polishing cloth, the surface of the object to be polished is liable to cause defects (scratches), and when the diameter of the single fiber is less than 3 μm. In the case where a cloth is used as the cloth for wiping the product, the surface of the cloth is flat and the wiping property is impaired. In the case where the cross-sectional shape of the single fiber is a profiled cross section other than the circular cross section, the diameter of the circumscribed circle is taken as the single fiber diameter. Further, the diameter of the single fiber is the same as described above, and can be measured by photographing the cross section of the fiber with a transmission electron microscope.

上述聚酯多纖絲B中，纖絲數並無特別限制，但較好在10~300條(更好為30~150條)之範圍內。另外，該聚酯多纖絲B之纖維形態並無特別限制，但以長纖維(多纖絲)較佳。單纖維之剖面形狀亦未特別限制，可為圓形、三角形、扁平、中空等習知之剖面形狀。另外，上述聚酯多纖絲B施行慣用之空氣加工、假撚捲縮加工亦無妨。尤其上述聚酯多纖絲B為假撚捲縮加工絲時，使用布料作為研磨用布料之情況下，由於布料之緩衝性獲得改善使缺陷(刮痕)之發生率下降而較佳。另外，上述聚酯多纖絲B為假撚捲縮加工絲時，使用布料作為擦拭製品用布料之情況下，可改善擦拭性能而較佳。又，上述假捲縮加工絲之捲縮率較好為4~30%之範圍內。In the above polyester multifilament B, the number of filaments is not particularly limited, but is preferably in the range of 10 to 300 (more preferably 30 to 150). Further, the fiber form of the polyester multifilament B is not particularly limited, but a long fiber (multifilament) is preferred. The cross-sectional shape of the single fiber is also not particularly limited, and may be a conventional cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape. Further, the polyester multifilament B may be subjected to conventional air processing or false twist crimping. In particular, when the polyester multifilament B is a false twist crimped yarn, when a fabric is used as the polishing fabric, it is preferable that the cushioning property of the fabric is improved to reduce the incidence of defects (scratches). Further, when the polyester multifilament B is a false twisted crimped yarn, when a fabric is used as the wiper fabric, the wiping performance can be improved. Further, the crimping rate of the above-mentioned false crimping processed yarn is preferably in the range of 4 to 30%.

形成上述聚酯多纖絲B之聚合物重要的是消艷劑之含有率為聚酯重量對比0.5重量%以下(更好0.1重量%以下，最好0重量%)之聚酯。消艷劑以多於聚酯重量對比0.5重量%而含於聚酯中時，使用布料作為研磨布用布料之情況下，使用研磨布研磨被研磨物時容易在被研磨物表面上產生缺陷(刮痕)而不佳。又，消豔劑以多於聚酯重量對比0.5重量%而含於聚酯中時，使用布料作為擦拭製品用布料時，包含於構成布料之纖維中之消豔劑粒子由於擦拭對象物與纖維之摩擦，而有掉落在對象物表面上使消豔劑本身成為塵埃，進而在對象物上產生深痕之情況。It is important that the polymer of the above polyester multifilament B is a polyester having a content of the deodorant of 0.5% by weight or less (more preferably 0.1% by weight or less, preferably 0% by weight) based on the weight of the polyester. When the deodorant is contained in the polyester in an amount of more than 0.5% by weight based on the weight of the polyester, when the cloth is used as the cloth for the polishing cloth, it is easy to cause defects on the surface of the object to be polished when the object to be polished is polished using the polishing cloth ( Scratches are not good. Further, when the anti-glare agent is contained in the polyester in an amount of more than 0.5% by weight based on the weight of the polyester, when the cloth is used as the cloth for the wiping product, the deodorant particles contained in the fibers constituting the cloth are wiped by the object and the fiber. The friction is applied to the surface of the object to cause the deodorant itself to become dust, thereby causing a deep mark on the object.

另外，形成上述聚酯多纖絲B之聚酯種類若為聚酯系聚合物則無特別限制，較佳之例示為聚對苯二甲酸乙二酯或聚對苯二甲酸丙二酯、聚對苯二甲酸丁二酯、使立體錯合聚乳酸、聚乳酸、第三種成分共聚合之聚酯等。至於該聚酯亦可為物質再生或化學再生之聚酯。再者，如特開2004-270097號公報或特開2004-211268號公報中所記載般，亦可使用含有特定磷化合物及鈦化合物之觸媒所得之聚酯。尤其是如後述之具有高沸水收縮率方面而言之共聚合聚酯最佳。該聚合物中，亦可依據需要在不損及本發明目的之範圍內包含一種或兩種以上之陽離子染料可染劑、抗著色劑、熱安定劑，但較好不含無機微粒子。Further, the polyester type forming the polyester multifilament B is not particularly limited as long as it is a polyester polymer, and is preferably exemplified by polyethylene terephthalate or polytrimethylene terephthalate or polypair. A butyl phthalate, a polyester obtained by copolymerizing a sterically miscible polylactic acid, a polylactic acid, or a third component. The polyester may also be a polyester which is regenerated or chemically regenerated. Further, as described in JP-A-2004-270097 or JP-A-2004-211268, a polyester obtained by using a catalyst containing a specific phosphorus compound and a titanium compound can also be used. In particular, the copolymerized polyester is preferred in terms of high boiling water shrinkage as described later. In the polymer, one or two or more kinds of cationic dye dyes, anti-colorants, and heat stabilizers may be contained as needed within the range not impairing the object of the present invention, but preferably no inorganic fine particles are contained.

上述聚酯多纖絲A與聚酯多纖絲B較好作為複合絲包含於布料中。若於布料中包含該複合絲，則使用該布料作為研磨布用布料之情況，可改善研磨性能。又，若於布料中包含該複合絲，則使用該布料作為擦拭製品用布料之情況，可改善擦拭性。此時，上述聚酯多纖絲A與聚酯多纖絲B之複合方法例示為氣流噴射交纏加工、拉齊假撚捲縮加工、包覆加工等。其中就明確形成芯鞘構造方面而言以氣流噴射交纏加工較佳。又，上述複合絲中，複合絲中所含之聚酯多纖絲A之絲長DA與聚酯多纖絲B之絲長DB之比DA/DB為1.05以上(較好為1.1~1.4)較佳。當該比DA/DB為1.05以上時，使用該布料作為研磨布用布料之情況，可改善研磨性能。又，該比DA/DB為1.05以上時，使用該布料作為擦拭製品用布料之情況，可改善擦拭性能。相反地，當該比DA/DB大於1.4時，有製造布料時之工程性下降之情況。The polyester multifilament A and the polyester multifilament B are preferably contained in the fabric as a composite yarn. If the composite yarn is included in the fabric, the fabric can be used as a cloth for the polishing cloth to improve the polishing performance. Moreover, when the composite yarn is included in the fabric, the fabric can be used as a cloth for a wiping product, and the wiping property can be improved. At this time, the composite method of the polyester multifilament A and the polyester multifilament B is exemplified by air jet entanglement processing, lazy false twist crimping processing, coating processing, and the like. Among them, it is preferable to form the core-sheath structure in terms of air jet entanglement processing. Further, in the above composite yarn, the ratio DA/DB of the filament length DA of the polyester multifilament A contained in the composite yarn to the filament length DB of the polyester multifilament B is 1.05 or more (preferably 1.1 to 1.4). Preferably. When the ratio DA/DB is 1.05 or more, the cloth is used as a cloth for a polishing cloth, and the polishing performance can be improved. Moreover, when the ratio DA/DB is 1.05 or more, the cloth is used as a cloth for wiping products, and the wiping performance can be improved. Conversely, when the ratio DA/DB is larger than 1.4, there is a case where the engineering property at the time of fabric production is lowered.

本發明之布料中之布料組織並無限定，可為織物亦可為編織物。The cloth structure in the cloth of the present invention is not limited, and may be a woven fabric or a woven fabric.

上述織物之組織並無特別限定，可為以一般方法製織者。層數可為單層，亦可為兩層以上。例示為例如，織組織為平織、斜紋織、緞紋織物等三原組織、變化組織、變化斜紋織等變化組織，經編雙重織、緯編雙重織之單面二重織、經編絲絨等。其中，以上述聚酯多纖絲A與聚酯多纖絲B構成之複合絲之浮絲條數為兩條以上之以經浮成分及/或緯浮成分而含有之織組織較佳。具體而言，以斜紋織組織或緞紋織組織(緞織組織)較佳。例如4/1之5片斜紋織組織之情況下，織組織中包含浮絲條數為4條緯浮成分。The structure of the above-mentioned woven fabric is not particularly limited, and it can be woven by a general method. The number of layers may be a single layer or two or more layers. For example, the woven structure is a three-original structure such as a plain weave, a twill weave, a satin weave, a changeable structure, a twill weave, and the like, a warp knitted double weave, a weft knitted double weave, a single weave, a warp knitted velvet, and the like. Among them, the number of the floating yarns of the composite yarn composed of the polyester multifilament A and the polyester multifilament B is preferably two or more, and the woven structure is contained by the float component and/or the weft float component. Specifically, a twill weave or a satin weave (satin weave) is preferred. For example, in the case of 5 twill weaves of 4/1, the number of floating wires included in the woven structure is 4 weft floating components.

織組織為斜紋織組織或緞紋織組織時，使用布料作為研磨布用布料之情況，可減低被研磨物表面之缺陷(刮痕)而較佳。亦即，組織之浮絲之浮起變高，藉由經絲與緯絲形成大的凹陷交點(組織點)，可藉研磨將屑捕集於該交點中，故可減低被研磨物表面缺陷(刮痕)。當織組織為平織組織時，交點之凹陷不足而有容易產生被研磨物表面缺點(刮痕)之情況。When the weave structure is a twill weave or a satin weave, it is preferable to use a cloth as a cloth for a polishing cloth to reduce defects (scratches) on the surface of the object to be polished. That is to say, the floating of the floating wire of the tissue becomes high, and by forming a large concave intersection point (tissue point) between the warp and the weft, the debris can be trapped in the intersection by grinding, thereby reducing the surface defect of the object to be polished. (scratch). When the woven structure is a plain weave structure, the depression of the intersection point is insufficient and there is a case where the surface defect (scratch) of the object to be polished is likely to occur.

又，織組織為斜紋織組織或緞紋織組織時，使用布料作為擦拭製品用布料之情況，可改善擦拭性而較佳。亦即，組織之浮絲浮起變高，故藉由經絲與緯絲形成大的凹陷交點(組織點)，由於可將擦拭之微小塵埃或油脂捕集於該下凹之交點中，而獲得優異之擦拭性及捕集性。當織組織為平織時，有交點之凹陷不足之情況。Further, when the weave structure is a twill weave or a satin weave, it is preferable to use a cloth as a cloth for wiping the article, and it is preferable to improve the wiping property. That is, the floating float of the tissue becomes high, so that a large concave intersection (tissue point) is formed by the warp and the weft, since the dust or the grease which is wiped can be trapped in the intersection of the concave, Excellent wiping and trapping properties. When the weaving structure is a plain weave, there is a case where the depression of the intersection is insufficient.

又，當布料為織物之情況，較好是作為聚酯多纖絲A為單獨絲條或者聚酯多纖絲A與其他絲條之複合絲僅搭配於織物之經絲與緯絲之一者中，另一者則搭配上述聚酯多纖絲B。當採用該構成時，由於織物內之空隙變大使織物之緩衝性獲得改善，故不僅可在被研磨物中形成細微溝槽，且亦可減低缺陷(刮痕)發生而較佳。此時，上述緩衝性以KES質地計測器之壓縮剛性係在0.08~0.9(更好為0.1~0.7)之範圍內，就減低被研磨物表面缺陷(刮痕)之發生率而言較佳。此處，壓縮剛性為緩衝性之代用特性，數值愈大代表緩衝性愈高，數值愈小代表緩衝性愈小。當布料之壓縮剛性(緩衝性)大時，不僅可在被研磨物上形成細微溝槽，亦可減低缺陷(刮痕)發生之理由迄今為止尚不清楚，但可推定為成為缺陷(刮痕)原因之異物即使附著在布料表面上，由於該布料之緩衝性而降低其影響之故。聚酯多纖絲A為搭配於織物之經絲及緯絲二者時，使用該布料作為研磨用布料之情況，由於織物之緩衝性下降，而有缺陷(刮痕)發生率大之情況。Moreover, when the fabric is a fabric, it is preferred that the polyester multifilament A is a single yarn or the composite yarn of the polyester multifilament A and other yarns is only matched with one of the warp and weft of the fabric. The other one is matched with the above polyester multifilament B. According to this configuration, since the cushioning property of the fabric is improved by the increase of the voids in the fabric, not only the fine grooves can be formed in the workpiece to be polished, but also the occurrence of defects (scratches) can be reduced. In this case, the cushioning property is preferably in the range of 0.08 to 0.9 (more preferably 0.1 to 0.7) in terms of the compression rigidity of the KES texture measuring instrument, and it is preferable to reduce the incidence of surface defects (scratches) of the object to be polished. Here, the compression rigidity is a substitute characteristic of the cushioning property, and the larger the numerical value, the higher the cushioning property, and the smaller the numerical value, the smaller the cushioning property. When the compression rigidity (buffering property) of the cloth is large, not only the fine groove can be formed on the object to be polished, but also the reason why the defect (scratch) is reduced is still unclear, but it can be presumed to be a defect (scratch). The foreign matter of the cause, even if it adheres to the surface of the cloth, is less affected by the cushioning property of the cloth. When the polyester multifilament A is used as the warp and weft of the woven fabric, the fabric is used as the polishing fabric, and the cushioning property of the fabric is lowered, and the occurrence rate of defects (scratches) is large.

又，布料為織物時，該織物之覆蓋因數CF較好在1500~4500(更好2300~4000)之範圍內。織物之覆蓋因數CF在該範圍內時，使用該布料作為研磨布用之情況，可在被研磨物上形成細微溝槽而較佳。又，織物之覆蓋因數CF若在該範圍內，則使用該布料作為擦拭製品用布料之情況可改善擦拭之性能而較佳。若織物之覆蓋因數CF未達1500，則對研磨布用織物施加研磨劑時，由於分散性不充分而有難以在被研磨物上形成細微溝槽之情況。又，若織物之覆蓋因數CF未達1500，則由於織物之剛性低，故使用該布料作為擦拭製品用布料之情況，有作業性降低之情況。當織物之覆蓋因數CF大於4500時，由於剛性過高而有難以在被研磨物上形成細微溝槽之情況。又，若織物之覆蓋因數CF大於4500，則由於剛性過高而有擦拭性能下降之情況。又，本發明之覆蓋因數CF係以下式表示者：Moreover, when the fabric is a fabric, the covering factor CF of the fabric is preferably in the range of 1,500 to 4,500 (more preferably 2,300 to 4,000). When the covering factor CF of the fabric is within this range, it is preferable to use the cloth as a polishing cloth to form fine grooves on the object to be polished. Further, if the covering factor CF of the fabric is within this range, it is preferable to use the cloth as the cloth for wiping the article to improve the wiping performance. When the covering factor CF of the woven fabric is less than 1,500, when the abrasive is applied to the woven fabric for a polishing cloth, it is difficult to form fine grooves on the workpiece due to insufficient dispersibility. Further, if the covering factor CF of the woven fabric is less than 1,500, since the rigidity of the woven fabric is low, the fabric is used as a cloth for wiping the product, and workability is lowered. When the covering factor CF of the fabric is more than 4500, it is difficult to form a fine groove on the object to be polished due to the rigidity being too high. Further, if the covering factor CF of the fabric is more than 4500, the wiping performance may be lowered due to the excessive rigidity. Further, the coverage factor CF of the present invention is expressed by the following formula:

CF=(DWp/1.1)1/2 ×MWp+(DWf/1.1)1/2 ×MWfCF=(DWp/1.1) 1/2 ×MWp+(DWf/1.1) 1/2 ×MWf

其中，DWp為經絲總纖度(dtex)、MWp為經絲織密度(條/2.54cm)、DWf為緯絲總纖度(dtex)、MWf為緯絲織密度(條/2.54cm)。Among them, DWp is warp total denier (dtex), MWp is warp density (bar/2.54 cm), DWf is weft total denier (dtex), and MWf is weft weave density (bar/2.54 cm).

又，本發明之布料為編織物之情況，編織物組織並無特別限定，可為以一般方法製編者。層數可為單層，亦可為兩層以上之多層。例如，編組織之較佳例示為平織、羅紋針織、兩面編織、雙反面編織(purl cam)、掛針編織、浮線編織、半畦編織(half cardigan)、紗羅編織、添毛編織、單梳櫛經平編織、單梳櫛經緞針織、雙梳櫛經絨編織、雙梳櫛經絨-經平編織、起絨經編、提花編織等。Further, in the case where the fabric of the present invention is a woven fabric, the woven fabric structure is not particularly limited, and it may be a woven fabric by a general method. The number of layers may be a single layer or a plurality of layers of two or more layers. For example, preferred examples of knitting are plain weave, rib weave, double weave, purl cam, hang stitch weave, float weave, half cardigan, leno weave, weave weave, single comb栉 平 flat weave, single comb 栉 satin knit, double comb velvet woven, double comb velvet - warp weaving, pile warp knitting, jacquard weaving, etc.

本發明之布料較好以上述聚酯多纖絲A與聚酯多纖絲B構成，但只要相對於布料重量在30重量%以下，則含有其他纖維亦無妨。The cloth of the present invention is preferably composed of the above-mentioned polyester multifilament A and polyester multifilament B. However, if it is 30% by weight or less based on the weight of the fabric, it may contain other fibers.

本發明之布料中，以厚度在0.10~0.80mm(更好為0.17~0.60mm)之範圍內較佳。若該厚度小於0.10mm，則使用該布料作為研磨布用布料之情況，由於緩衝性降低而有容易在被研磨物表面上產生缺陷(刮痕)之情況。又，若該厚度小於0.10mm，則使用該布料作為擦拭製品用布料之情況，由於布料之剛性變低而有損及作業性之情況。相反地若厚度大於0.80mm，則使用該布料作為研磨用布料之情況，有作業性下降之情況。又，若厚度大於0.80mm，則使用該布料作為擦拭製品用布料之情況，有剛性過高而使擦拭性降低之情況。The fabric of the present invention is preferably in the range of 0.10 to 0.80 mm (more preferably 0.17 to 0.60 mm). When the thickness is less than 0.10 mm, the cloth is used as the cloth for the polishing cloth, and the cushioning property is lowered to cause occurrence of defects (scratches) on the surface of the workpiece. Moreover, when the thickness is less than 0.10 mm, the cloth is used as the cloth for wiping products, and the rigidity of the cloth is lowered to impair the workability. On the other hand, when the thickness is more than 0.80 mm, the cloth is used as the polishing cloth, and the workability is lowered. Moreover, when the thickness is more than 0.80 mm, the cloth is used as a cloth for wiping products, and the rigidity is too high and the wiping property is lowered.

上述布料可藉由以下製造方法製造。亦即，作為聚酯多纖絲A用，係以島成分及海成分形成之海島型複合纖維，島成分係使用由消艷劑之含有率為聚酯重量對比0.5重量%以下(更好為0.1重量%以下，最好為0重量%)之聚酯所組成且島成分直徑為50~1500nm(較好為100~1000nm，更好為400~800nm，最好為520~800nm)之海島型複合纖維，另一方面，作為聚酯多纖絲B用，係使用消艷劑之含有率為聚酯對比重量0.5重量%以下(更好為0.1重量%以下，最好為0重量%)之聚酯所組成之使用單纖維直徑3μm以上之聚酯多纖絲編織成布料後，藉由以鹼性水溶液溶解去除上述海島型複合纖維之海成分，藉此製造上述之布料。The above cloth can be produced by the following manufacturing method. In other words, the polyester multifilament A is an island-in-sea type composite fiber formed of an island component and a sea component, and the island component is used in an amount of 0.5% by weight or less based on the weight of the polyester. An island type composed of 0.1% by weight or less, preferably 0% by weight of the polyester and having an island component diameter of 50 to 1500 nm (preferably 100 to 1000 nm, more preferably 400 to 800 nm, and most preferably 520 to 800 nm) On the other hand, as the polyester multifilament B, the content of the use of the deodorant is 0.5% by weight or less (more preferably 0.1% by weight or less, preferably 0% by weight) based on the comparative weight of the polyester. After the polyester multifilament having a single fiber diameter of 3 μm or more, which is composed of a polyester, is woven into a cloth, the above-mentioned fabric is produced by dissolving and removing the sea component of the sea-island type composite fiber in an alkaline aqueous solution.

其中，上述海島型複合纖維中，構成該纖維之聚合物只要是海成分聚合物溶解性比島成分聚合物高之組合，則可為任意，但最好為溶解速度比(海/島)為200以上。當該溶解速度比未達200時，由於在使纖維剖面中央部份之海成分溶解期間亦會使纖維剖面表層部分之島成分之一部份溶解，因此為了完全溶解去除海成分，島成分之比例亦會些許減量，而發生島成分之厚度不均或因溶劑浸蝕而發生強度劣化，容易產生起毛或成團等之品質問題。In the above-mentioned sea-island type composite fiber, the polymer constituting the fiber may be any combination of sea component polymer solubility and island component polymer, but it is preferable that the dissolution rate ratio (sea/island) is 200. the above. When the dissolution rate ratio is less than 200, since one part of the island component of the surface portion of the fiber section is dissolved during the dissolution of the sea component in the central portion of the fiber section, the island component is completely dissolved to remove the sea component. The ratio is also slightly reduced, and the thickness of the island component is uneven or the strength is deteriorated due to solvent etching, which is liable to cause quality problems such as fluffing or agglomeration.

海成分聚合物只要是與島成分之溶解速度比在200以上則可為任何聚合物，但最好為纖維形成性良好之聚酯、聚醯胺、聚苯乙烯、聚乙烯等。例如，作為鹼水溶液易溶性之聚合物，較好使用聚乳酸、超高分子量聚環氧烷縮合系聚合物、聚乙二醇系化合物共聚合聚酯、聚乙二醇系化合物與5-鈉磺酸間苯二甲酸之共聚合聚酯。又，尼龍6為具有甲酸溶解性，聚苯乙烯‧聚乙烯極溶於甲苯等有機溶劑。其中，為使鹼易溶解性及海島剖面形成性兩者兼具，作為聚酯系聚合物，較好為6~12莫耳%之5-鈉磺基間苯二甲酸與3~10重量%之分子量4000~12000之聚乙二醇共聚合而成之固有黏度為0.4~0.6之聚對苯二甲酸乙二酯系共聚合聚酯。此處，5-鈉間苯二甲酸有助於提高親水性與熔融黏度，聚乙二醇(PEG)則改善親水性。另外，PEG之分子量愈大，認為其高次構造所引起之親水性增加效果變大，但由於反應性變差而成為摻合物系，因此就耐熱性‧紡絲安定性等之點而言較不好。又，若聚合物量為10重量%以上時，由於有原本熔融黏度下降作用，因此難以達成本發明之目的。因而，使兩成分在上述範圍內共聚合較佳。The sea component polymer may be any polymer as long as it has a dissolution rate ratio of 200 or more to the island component, but is preferably a polyester, polyamide, polystyrene, polyethylene or the like which is excellent in fiber formability. For example, as the polymer which is easily soluble in an aqueous alkali solution, polylactic acid, an ultrahigh molecular weight polyalkylene oxide condensation polymer, a polyethylene glycol compound copolymerized polyester, a polyethylene glycol compound, and 5-sodium are preferably used. Copolymerized polyester of sulfonic acid isophthalic acid. Further, nylon 6 has a solubility in formic acid, and polystyrene ‧ polyethylene is extremely soluble in an organic solvent such as toluene. Among them, in order to make both the alkali solubility and the island profile formation property, as the polyester polymer, it is preferably 6 to 12 mol% of 5-sodium sulfoisophthalic acid and 3 to 10% by weight. A polyethylene terephthalate copolymerized polyester having an intrinsic viscosity of 0.4 to 0.6 obtained by copolymerization of polyethylene glycol having a molecular weight of 4000 to 12,000. Here, 5-sodium isophthalic acid contributes to the improvement of hydrophilicity and melt viscosity, and polyethylene glycol (PEG) improves hydrophilicity. In addition, the higher the molecular weight of PEG, the higher the hydrophilicity-increasing effect by the higher-order structure, but the blending system is deteriorated due to the deterioration of the reactivity. Therefore, in terms of heat resistance, spinning stability, and the like, Not good. Further, when the amount of the polymer is 10% by weight or more, the original melt viscosity is lowered, so that it is difficult to achieve the object of the present invention. Therefore, it is preferred to copolymerize the two components within the above range.

另一方面，島成分聚合物亦可為消艷劑之含有率為聚酯重量對比0.5重量%以下(更好為0.1重量%以下，最好為0重量%)之聚酯且與海成分具有溶解速度差之聚酯聚合物，但較好為如上述之纖維成形性之聚對苯二甲酸乙二酯或聚對苯二甲酸丙二酯、聚對苯二甲酸丁二酯、使聚乳酸、第三成分共聚合而成之聚酯等之聚酯。該聚合物中，亦可依據需要在不損及本發明目的之範圍內包含一種或兩種以上之陽離子染料可染劑、抗著色劑、熱安定劑，但較好不含無機微粒子。On the other hand, the island component polymer may be a polyester having a content of the deodorant of 0.5% by weight or less (more preferably 0.1% by weight or less, preferably 0% by weight) based on the weight of the polyester and having a sea component. a polyester polymer having a poor dissolution rate, but preferably a fiber-forming polyethylene terephthalate or polytrimethylene terephthalate, polybutylene terephthalate, or polylactic acid as described above A polyester such as a polyester obtained by copolymerizing a third component. In the polymer, one or two or more kinds of cationic dye dyes, anti-colorants, and heat stabilizers may be contained as needed within the range not impairing the object of the present invention, but preferably no inorganic fine particles are contained.

由上述海成分聚合物與島成分聚合物構成之本發明海島型複合纖維較好熔融紡絲時之海成分熔融黏度大於島成分聚合物之熔融黏度。具有該關係時，海成分之複合重量比率即使少至小於40%，則島彼此接合，難以成為與島成分大部分接合之海島型複合纖維不同之複合纖維。The sea-island type composite fiber of the present invention comprising the sea component polymer and the island component polymer preferably has a melt viscosity of the sea component at the time of melt spinning greater than a melt viscosity of the island component polymer. In this relationship, even if the composite weight ratio of the sea component is as small as less than 40%, the islands are joined to each other, and it is difficult to form a composite fiber different from the sea-island type composite fiber in which most of the island components are joined.

較佳之熔融黏度比(海/島)為1.1~2.0，尤其是1.3~1.5之範圍。若該比小於1.1倍時，熔融紡絲時島成分不容易接合，另一方面若超過2.0倍時，由於黏度差異過大而易使紡絲狀形降低。The preferred melt viscosity ratio (sea/island) is from 1.1 to 2.0, especially from 1.3 to 1.5. When the ratio is less than 1.1 times, the island component is not easily joined at the time of melt spinning, and when it exceeds 2.0 times, the difference in viscosity is excessively large, and the spin shape is liable to lower.

接著，由於在溶解去除較多量海成分而製造極細纖維之情況之生產性變高，反而有可能使所得極細纖維之細度亦變得顯著而可在被研磨物上形成細微溝槽，因此島數以100以上(更好為300~1000)較佳。再者，若島數過量變得過多時，不僅紡絲模嘴之製造成本變高，且由於加工精度本身亦容易降低，因此以10000以下者較佳。In the case where ultrafine fibers are produced by dissolving and removing a large amount of sea components, the productivity is high, and the fineness of the obtained ultrafine fibers may be conspicuous, and fine grooves may be formed on the object to be polished. Preferably, the number is 100 or more (more preferably 300 to 1000). In addition, when the number of islands is excessively large, not only the manufacturing cost of the spinning nozzle is increased, but also the processing accuracy itself is easily lowered. Therefore, it is preferably 10,000 or less.

其次，島成分之直徑必須在50~1500nm(較好為100~1000nm，更好為400~800nm，最好為520~800nm)之範圍。又，海島複合纖維剖面內之各島其直徑愈均勻則由於由去除海成分獲得之極細多纖絲組成之織物之品質及耐久性獲得改善而較佳。Second, the diameter of the island component must be in the range of 50 to 1500 nm (preferably 100 to 1000 nm, more preferably 400 to 800 nm, and most preferably 520 to 800 nm). Further, the more uniform the diameter of each island in the island composite fiber section is, the better the quality and durability of the fabric composed of the extremely fine multifilament obtained by removing the sea component are improved.

上述海島型複合纖維中，其海島複合重量比率(海：島)較好為40：60~5：95之範圍，尤其是以30：70~10：90之範圍較佳。若在該範圍內，則可將島間之海成分厚度變薄，而使海成分之溶解去除變得容易，且由於島成分轉變成極細纖維變得容易而較佳。其中當海成分之比例超過40%時，海成分之厚度過厚，另一方面當小於5%時海成分之量過少使島間之接合不容易發生。In the above-mentioned sea-island type composite fiber, the sea-island composite weight ratio (sea: island) is preferably in the range of 40:60 to 5:95, particularly preferably in the range of 30:70 to 10:90. If it is in this range, the thickness of the sea component between the islands can be made thin, and the dissolution and removal of the sea component can be easily performed, and it is preferable that the island component is converted into ultrafine fibers. When the proportion of the sea component exceeds 40%, the thickness of the sea component is too thick, and on the other hand, when the amount of the sea component is less than 5%, the amount of the sea component is too small to cause the joint between the islands to be less likely to occur.

上述海島型複合纖維中，其島間之海成分厚度較好為500nm以下，最好為20~200nm之範圍。若該厚度超過500nm時，由於溶解去除該厚度之海成分期間進行島成分之溶解，不僅使島成分間之均質性下降，且容易造成起毛或剝離等穿戴時之缺陷且也易產生染色斑點。In the sea-island type composite fiber, the sea component thickness between the islands is preferably 500 nm or less, preferably 20 to 200 nm. When the thickness exceeds 500 nm, the dissolution of the island component during the dissolution and removal of the sea component of the thickness causes not only the homogeneity between the island components but also the defects at the time of wearing such as fuzzing or peeling, and the occurrence of dye spots.

上述之海島型複合纖維可藉由以下方法容易地製造。亦即，首先使熔融黏度高且易溶解性之聚合物與熔融黏度低且難溶解性之聚合物，以前者作為海成分，後者作為島成分之方式進行熔融紡絲。其中，海成分與島成分之熔融黏度之關係具重要性，海成分之比率變小而使島間之厚度變小及在海成分之熔融黏度小之情況下島間之一部份流路成為使海成分高速流動，而難以引起島間接合而不佳。The above-described sea-island type composite fiber can be easily produced by the following method. That is, first, a polymer having a high melt viscosity and a low solubility, and a polymer having a low melt viscosity and poor solubility are used as a sea component, and the latter is melt-spun as an island component. Among them, the relationship between the sea component and the melt viscosity of the island component is important, the ratio of the sea component becomes small, and the thickness between the islands becomes small, and in the case where the melt viscosity of the sea component is small, part of the flow path between the islands becomes the sea. The composition flows at a high speed, and it is difficult to cause poor inter-island bonding.

熔融紡絲使用之紡絲模嘴可使用具有用以形成島成分之中空針群或細微孔群者等之任意者。亦可為例如使由中空針或微細孔押出之島成分與以埋在其間形式設計流路之海成分流合流，藉由使之壓縮而形成海島斷面之此種紡絲模嘴。較佳使用之紡絲模嘴之例顯示於圖1及2，但並非必定限定於該等。又圖1為中空針吐出至海成分樹脂儲存部分並使之合流壓縮之方式，圖2為以微細孔方式取代中空針形成島之方法。As the spinning die used for melt spinning, any one having a hollow needle group or a fine pore group for forming an island component can be used. For example, such a spinning die in which an island component which is extruded by a hollow needle or a micropore is combined with a sea component flow in which a flow path is designed to be buried therebetween is formed by compression to form a sea-island section. Examples of preferred spinning nozzles are shown in Figures 1 and 2, but are not necessarily limited to these. Further, Fig. 1 shows a manner in which the hollow needle is discharged to the sea component resin storage portion and merged and compressed. Fig. 2 shows a method of replacing the hollow needle to form an island by microporous means.

吐出之海島型複合纖維以冷風固化，較好在400~6000m/分鐘下熔融紡絲後捲取。所得未延伸絲繼續另外之延伸步驟成為具有期望之強度‧伸長度‧熱收縮特性之複合纖維，或者，一旦順利捲取後以一定速度捲出至輥上，接著繼續延伸步驟之後捲取之方法之任一種均無妨。The island-type composite fiber spit out is solidified by cold air, and is preferably taken up after melt spinning at 400 to 6000 m/min. The resulting undrawn filament continues the additional extension step into a composite fiber having a desired strength, elongation, and heat shrinkage characteristics, or a method of winding up to a roll at a certain speed once it is smoothly taken up, and then continuing the stretching step. Any one of them is fine.

此處，延伸步驟較好為慣用之輥延伸步驟。又，為了高效率地製造具有特別細微島徑之海島型複合纖維，採用通常預先伴隨著所謂之配向結晶化之縮頸延伸(配向結晶化延伸)，不使纖維構造改變，僅使纖維直徑極細化之流動延伸步驟亦可。為了使流動延伸容易，較好使用熱容量大的水介質使纖維均勻預熱，並以低速延伸。藉由如此可延伸時溶液形成流動狀態，可不伴隨纖維之微細構造發達而輕易地延伸。就此製程，較好海成分與島成分均使用玻璃轉移溫度100℃以下之聚合物，尤其適用聚對苯二甲酸乙二酯、聚對苯二甲酸丁二酯、聚乳酸、聚對苯二甲酸丙二酯等聚酯。具體而言，係浸漬在60~100℃，更好60~80℃範圍之溫水浴中實施均勻加熱，較好以延伸倍率10~30倍，供給速度為1~10m/分鐘，捲起速度為300m/分鐘以下，特別是10~300m/分鐘之範圍內實施。預熱溫度不足及延伸速度過快之情況下，會有無法達成目標之高倍率延伸之情況。Here, the stretching step is preferably a conventional roller stretching step. In addition, in order to efficiently produce a sea-island type composite fiber having a particularly fine island diameter, a necking extension (orthogonal crystallization extension) which is usually accompanied by so-called alignment crystallization is used, and the fiber diameter is extremely fine without changing the fiber structure. The flow extension step can also be used. In order to facilitate the flow extension, it is preferred to use an aqueous medium having a large heat capacity to uniformly preheat the fibers and to extend at a low speed. By forming the flow state of the solution when it is thus stretchable, it can be easily extended without accompanying the development of the fine structure of the fiber. For this process, it is better to use a polymer with a glass transition temperature of 100 ° C or less for sea components and island components, especially for polyethylene terephthalate, polybutylene terephthalate, polylactic acid, polyterephthalic acid. Polyester such as propylene glycol. Specifically, it is immersed in a warm water bath of 60 to 100 ° C, more preferably 60 to 80 ° C, and is uniformly heated, preferably with a stretching ratio of 10 to 30 times, a supply speed of 1 to 10 m/min, and a winding speed of It is implemented within a range of 300 m/min or less, particularly 10 to 300 m/min. When the preheating temperature is insufficient and the extension speed is too fast, there is a case where the high magnification extension of the target cannot be achieved.

為了提昇延伸絲之強伸長度之等機械特性，以所得流動狀態延伸之延伸絲可以慣用之方法在60~220℃之溫度下配向結晶化延伸。該延伸條件在其範圍以外之溫度下，將成為所得纖維之物性不足者。而且，其延伸倍率係隨著熔融紡絲條件、流動延伸條件、配向結晶化延伸條件等而變，但較好在以該配向結晶化延伸條件下可延伸之最大延伸倍率之0.6~0.95倍下延伸。In order to improve the mechanical properties such as the strong elongation of the stretched yarn, the stretched wire extending in the obtained flow state can be subjected to the crystallization and elongation at a temperature of 60 to 220 ° C by a conventional method. If the extension condition is outside the range, the physical properties of the obtained fiber will be insufficient. Further, the stretching ratio varies depending on the melt spinning conditions, the flow stretching conditions, the alignment crystallization stretching conditions, and the like, but is preferably 0.6 to 0.95 times the maximum stretching ratio which can be extended under the conditions of the alignment crystallization extension. extend.

使用以上說明之海島型複合纖維(海島型複合延伸絲)與上述聚酯多纖絲B製造布料後，以鹼水溶液溶解去除海島型複合纖維之海成分，藉此獲得本發明織布料。另外，亦可在藉由上述之鹼水溶液溶解去除海成分之處理之前及/或之後施加染色加工或親水加工等各種加工。The fabric of the present invention is obtained by dissolving and removing the sea component of the sea-island type composite fiber by using an island-in-sea composite fiber (island-type composite stretched yarn) and the above-described polyester multifilament B as described above, and then dissolving and removing the sea component of the sea-island type composite fiber. Further, various processes such as dyeing processing or hydrophilic processing may be applied before and/or after the treatment of dissolving and removing the sea component by the above aqueous alkali solution.

如此所得織布料由於含有上述之聚酯多纖絲A及聚酯多纖絲B，在作為研磨布用布料使用時，可降低被研磨物表面之缺陷(刮痕)發生率，且可在被研磨物上形成細微溝槽。另外，使用該布料作為擦拭製品用布料時，使擦拭性良好且減少灰塵產生成為可能。此時，布料之表面及/或其背面以KES質地計測器測定摩擦係數若為0.4~0.9之範圍內則可獲得優異之擦拭性而較佳。When the woven fabric thus obtained contains the polyester multifilament A and the polyester multifilament B described above, when used as a cloth for a polishing cloth, the incidence of defects (scratches) on the surface of the workpiece can be reduced, and A fine groove is formed on the object to be polished. Further, when the cloth is used as a cloth for wiping products, it is possible to improve the wiping property and reduce the generation of dust. In this case, it is preferable that the surface of the cloth and/or the back surface thereof have a coefficient of friction of 0.4 to 0.9 when the coefficient of friction is measured by a KES texture measuring instrument.

如此獲得之布料中，經方向之伸長度與緯方向之伸長度均為200%以下時，使用該布料作為研磨布用布料之情況下，可降低被研磨物表面之缺陷(刮痕)且使在被研磨物上形成細微溝槽成為可能而較佳。In the cloth thus obtained, when the elongation in the warp direction and the elongation in the weft direction are both 200% or less, when the cloth is used as the cloth for the polishing cloth, the defects (scratches) on the surface of the object to be polished can be reduced and It is possible to form fine grooves on the object to be polished.

又，上述布料中之親水化劑以相對於布料重量為0.2~10.0重量%之範圍附著時，使用布料作為研磨用布料之情況下可降低被研磨物表面之缺陷(刮痕)且使在被研磨物上形成細微溝槽成為可能而較佳。Further, when the hydrophilizing agent in the cloth is attached in a range of 0.2 to 10.0% by weight based on the weight of the cloth, when the cloth is used as the polishing cloth, the surface of the object to be polished can be reduced (scratches) and the film can be removed. It is possible to form fine grooves on the abrasive.

至於上述親水化劑只要是與構成纖維具有親和性之親水性聚合物則亦可使用任意者。最好使用與聚酯系纖維具有親和性之親水性聚合物。較佳之例示為例如，使聚乙二醇二丙烯酸酯或其衍生物、聚烷二醇(聚乙二醇、聚丙二醇等)與對苯二甲酸及/或間苯二甲酸及低級烷二醇(乙二醇等)共聚合而成之嵌段共聚物等。此時，可僅使用一種親水劑，或者亦可倂用兩種以上之親水劑。親水劑之施加方法並無特別限制，可例示為例如與染色之同浴加工、軋染法、平網印花法、回轉式篩網印刷法、皮輥印刷法、凹版皮輥法、輕觸塗佈輥法、泡加工機之方法等。Any of the above-mentioned hydrophilizing agents may be any one as long as it is a hydrophilic polymer having affinity with the constituent fibers. It is preferred to use a hydrophilic polymer having affinity with the polyester fiber. Preferably, for example, polyethylene glycol diacrylate or a derivative thereof, polyalkylene glycol (polyethylene glycol, polypropylene glycol, etc.) and terephthalic acid and/or isophthalic acid and lower alkanediol are used. A block copolymer or the like obtained by copolymerization (such as ethylene glycol). In this case, only one hydrophilic agent may be used, or two or more hydrophilic agents may be used.

此處，以JIS L1096-1998 6.26.1滴下法測定之吸水速度為10秒以下(更好為7秒以下)就有效地在被研磨物上形成細微溝槽方面而言較佳。吸水速度若為10秒以上，則在研磨布用布料上賦予研磨劑時，由於擴散性變不充分而有難以在被研磨物上形成細微溝槽之情況。Here, it is preferable that the water absorption speed measured by the JIS L1096-1998 6.26.1 dropping method is 10 seconds or less (more preferably 7 seconds or less), and it is effective to form a fine groove on the object to be polished. When the water absorption speed is 10 seconds or more, when the polishing agent is applied to the cloth for polishing cloth, the diffusibility is insufficient, and it is difficult to form fine grooves on the workpiece.

又，若使用在上述布料上貼合由有機材料構成之薄片之複合薄片作為研磨布用複合薄片時，由於可提高薄片之剛性，故可降低被研磨物表面之缺陷(刮痕)發生率且可在被研磨物上形成細微之溝槽而較佳。Further, when a composite sheet in which a sheet made of an organic material is bonded to the above-mentioned cloth is used as a composite sheet for a polishing cloth, since the rigidity of the sheet can be increased, the occurrence rate of defects (scratches) on the surface of the workpiece can be reduced.
