，使用喷吹冷卻風均一地使熔融紡紗紗條快速冷卻之冷 卻裝置進行冷㈣，進-步用在料卻裝置之垂直方向 下方的環狀供油裝置對每支單紗進行供油後，於集束引 導3L供油裝置中使紗條聚集成束並進行第2段的供油。第 2段供油之後，在因摩必、i & 應乂要而賦予交錯後捲成包之第1步 驟法，從可得到粗細不均或絨毛極少之聚酿胺纖維之點 ::::面為佳。同時，冷卻裝置方面係以環狀冷卻 :::佳’以從在圓周上運行之紡紗紗條 喷吹冷卻風之外吹式 朝汁 朝内側噴吹… 部裝置、從紡紗紗條的外側 々風之内吹式環狀冷卻裝置較佳，特別以 外吹式環狀冷卻裝置更佳。 特別以 將本發明之聚酿胺纖維 據第1圖及第s国I仏方法的較佳例之一依 發明之合成纖雄1^明°第1圖及第1圖係呈示本 用外吹式環狀划的製造步驟之一例的概略圖’第1圖係使 環狀型冷部=部裝置3之—例、第1圖係使用内吹式 1 圖之製造步驟沾/ 例。以下的說明中，第1圖及第 ^ f的基本構成相同，故省略共同符號之說明 201231746 第1圖中，經溶融之聚醯胺從喷嘴i吐出，通過 下保溫區2之後’在降低長方向的纖度不均之目的下，由 設置在嗔嘴中心下方之外吹式環狀型冷卻裝置3,從访出 紗條之内側朝向外側喷吹冷卻風，使各單紗從噴嘴面以 均一的距離急速冷卻、固化。進-步宜在使紗條聚集成 束之則，在BJ盤之外周部接觸單纱之圓盤型的引導部， 與在引導部之正上方沿著引導部外周形成之具有油劑吐 出用的環形狹縫之環狀供油裝置4，藉此對每支單吵進行 供油後’於集束引導型供油裝置5中使紗條聚集成束並進 行第2段的供油。供油後，應必要在交錯喷嘴6予以 交錯，通過拉取親7、拉伸輕8 ’以捲紗機(捲繞裝置)9捲 繞。而且，係纖維長纖、⑴系纖維製品包裝。並且， 在捲成包裝前，可經由2組以上之親進行拉伸，此時，經 由拉伸而賦予之交錯會有退繞之情形，因此，可將拉伸 倍率降低或拉伸後再次賦予交錯即可。 在喷嘴下保溫區2中，使蒸氣朝嘴嘴面喷出並使喷嘴 下保溫區2中充滿蒸氣者，係喷嘴之吐出口周邊的聚合物 及聚。物中所含的低聚物與氧產生反應而固化，而有抑 制成為所謂噴嘴污染的效果’故為適用。此時，蒸氣之 喷出壓力宜成為〇1至〇 5kPa，喷出壓力過小日夺，喷嘴下 保溫區之氧氣濃度増高，噴嘴面污染之抑制效果變小， =噴出壓力過大時，會引發吐出紗條的擺動，因而 關係到烏斯特不均度的惡化。 :排列於圓形的周邊上之紡出紗條冷卻時，使用環狀 々部裝置，對紗條喷吹冷卻風成外吹放射狀者，係可從 -10- 201231746 吐自喷嘴之聚酿胺產生之低聚物成分或 氣不滯留在纺炒裝置内部而開放至外部，故為適用。’·、 在上述第丨圖之製造步驟中係使用外吹式環狀型冷 卻裝置3,然亦可使用第5圖所示之内吹式環狀型冷卻裝 置18以取代外吹式環狀型冷卻裝置3。内吹式環狀型冷卻 裝置18係以圍住纺出紗條之方式而言史置在喷嘴中心下方 ’從纺出紗條之外側朝向内側噴吹冷卻風，使各單紗從 喷嘴面以均一的距離急速冷卻、固化。 冷卻起始點距冑，亦即從喷嘴面至環狀型冷卻裝置 中之冷卻風喷吹部上端之距離(1〇以1〇至7〇随為佳以 10至60mm更佳’以1〇至5()随進—步更佳。冷卻起始點 距離過短時，從環狀型冷卻裝置吹出之冷卻風在喷嘴面 附近’因噴嘴面溫度降低使得熱塑性聚合物之吐出安定 性惡化’而使纺紗紗條斷裂或絨毛增加。而且，冷卻起 始點距離過長時，由於在進行利用冷卻風之均一且急速 的冷部剛會使聚醯胺固化，因此纖維的長方向之纖度變 動（烏斯特不均度）容易變大，當製成織物時會有質感降 低之傾向。 褒狀里冷卻裝置中之冷卻風的風速宜為15至60 m/ 以20至55m/min更佳’以25至50m/min又更佳。冷 卻風速過小時’由於單紗之均一且急速的冷卻變為不足 或冷卻乡>、條之伸展過小’故易因干擾而引起紗的擺動 使烏斯特不均度增大。並且，在聚合物之冷卻不足而與 引導4接觸的情形下，由於絨毛或紡紗斷裂頻繁發生， 故在作成織物時的質感劣化。冷卻風速過大時，因對各 -11- 201231746 單紗過於施加張力使紗條微振而増大烏斯特不均度、且 在紡紗時増加紗的斷裂。 環狀型冷卻裝置中之冷卻風的溫度宜為5至50°C，以 10至40°C為佳，以15至35°C更佳。冷卻風之溫度過低時 ，噴嘴下保溫區之溫度降低，使噴嘴面之溫度降低，因 此，紗條強度有降低之傾向’冷卻風之溫度過高時，難 以使紗條均一冷卻，且易使紗條之冷卻不足，除了烏斯 特不均度增大之外’紡紗時亦有增加斷紗之傾向。 環狀型冷卻裝置中之冷卻風噴吹部的垂直方向之長 度且為100至500mm’以150至400mm為佳，以200至 3 5 0mm更佳。冷卻風噴吹長度過長時，對單紗施加的張 力增大，造成紡紗斷裂，冷卻風噴吹長度過短時，由於 在單紗之冷卻不足的情況下賦予油劑，而造成絨毛減少 及紡紗斷裂。 可經環狀供油裝置處 上運行之紡紗紗條的 通過環狀型冷卻裝置之單紗， 理。該環狀供油裝置係配置在圓周 内側。 第4圖係呈示本發明中適用之環狀供油襞置之

In other words, when the single yarn has a fineness of less than L2dtex, the fine yarn is processed into a fabric, which can obtain an extremely soft hand, and the heat preservation property is also higher than that of the general single yarn. The false-twisted processing yarn is further improved. Therefore, the demand for fine-twisted processed yarns in the market has become a basic one. For example, the above-mentioned polyamide fine fiber is a 1 2dtpviV-r-^w, tan sand in the early yarn fineness. In the fiber composed of the polyamide HZ polyamidamide fiber, a false enamel having a predetermined coefficient, elongation, and hot water shrinkage ratio, and a pseudo-P can be used to impart a soft feeling to the woven fabric.

Uniformly supplied to a single yarn room (Patent Document No. 2005-320655) The problem of the above-mentioned patent documents 1 and 2 is further reduced to less than 5 dtex by the method described in the above-mentioned Patent Documents 1 and 2, JP-A-2007-12649. In the case of extremely fine polyamide fibers, it is difficult to change the uniform oil. Therefore, the extremely fine one-step and the texture of the fluff are deteriorated, and the single yarn becomes larger. As a result, the false twist processing is performed. When the woven fabric is supplied, there is a problem that the smoothness or the texture of the fabric is lowered, and the dyeing plaque or the like is disadvantaged. The problem is that the oil supply method described in Patent Document 3 is used for integration. The bundle is given an oil agent. When the single yarn fineness is (10) fiber, the average strength of a single yarn is reduced. 'Cuixin and the friction will be generated. The fiber before the oil agent will have a special problem with the large friction coefficient of 201231746. Therefore, the friction between the single yarns, the friction between the single yarn and the guide portion causes the single yarn to break, and it is difficult to impart a single yarn to the inner layer of the bundled yarn, and the moisture adhesion between the single yarns is poor, or The fiber structure between the yarns is poor, so there is a disadvantage that the texture is lowered. Furthermore, when applying the method described in the patent document 4, the uniformity of the uniformity of the oil agent is advantageous, but the application of the agent in the longitudinal direction of the fiber becomes difficult, and the oil agent is unevenly distributed in the long direction. The structural difference of the fibers or the unevenness of the friction coefficient becomes large. Therefore, in the step and the processing step, the yarn is rubbed with the yarn guide or the like to cause unevenness in the dyeing, and staining occurs after the dyeing, and there is a disadvantage that the fabric cannot be felt. The purpose of this I month is to solve the above-mentioned prior art problem of providing high flexibility, smoothness, drape, high water absorption, high density, and dyed high-quality guanamine fine fiber for the knitted fabric. .

In a further preferred embodiment, excellent barrier properties can also be imparted. [Embodiment] [Embodiment of the Invention] Hereinafter, embodiments of the present invention will be described in detail. A homopolymer or copolymer of polyamines used in the polyamide fine fibers of the present invention. The polyamines are salts of indoleamines, aminocarboxylic acids or diamines and dicarboxylic acids. A melt-formable polymer having a guanamine bond formed. 'Polyuramine can use various polyamines without particular limitation. In the point of fiber formation of this force and mechanical properties, polycaprolactam (nylon 6), :-methylenebisdiamine ( Nylon 66) is preferred. The copolymer of nylon 6, nylon 66 = decylamine may be copolymerized with other aminocaproic acid or internal amine in a ratio of _i: with respect to the total monomer unit. The viewpoint of the sulfuric acid phase-determination of the polyamine used in the present invention is preferably from 2.0 to 3.5, and: ...y female $ ο η μ. /X. The ruthenium is better and the best is 25 2.7. The above sulfuric acid phase. The method for measuring the viscosity is based on the following description of the polymer of the present invention except for the main component. The purpose of the present and the purpose of the present invention is to copolymerize the second component, or to impart hygroscopicity, and the cocoa may be mixed as needed, and in addition to the object of the present invention, the polyethylene ratio is The pyrrolidone is contained in polyamine. Among the polyamines used in the present invention, there are various additives, such as an absorbent, an infrared absorbing agent, a (crystalline) nucleating agent, and a fluorescent whitening agent. The method for producing the polyamidamide ultrafine fiber of the present invention is not particularly limited as long as the polyamine fine microfiber of the present invention can be obtained, and the following method should be used: first, the polyamine is grafted from the periphery of the spinning nozzle. The discharge hole arranged in a circumferential direction is discharged by the discharge spun yarn, and the inside or the outside of the melt spun yarn spouted from the discharge hole below the nozzle center portion is uniformly melted by the spray cooling air. The cooling device for rapid cooling of the spun yarn is cooled (4), and the oil supply device for each single yarn is supplied with oil by the annular oil supply device below the vertical direction of the device, and is then used in the bundle guiding 3L oil supply device. The slivers are gathered into a bundle and the oil supply in the second stage is carried out. After the second paragraph is supplied with oil, in the first step of the method of interlacing and wrapping into a package, it is possible to obtain the point of the polystyrene fiber which has uneven thickness or low fluff::: : The face is better. At the same time, the cooling device is cooled in a ring::: good to blow the cooling air from the spinning sliver running on the circumference, and blow it toward the inside toward the inside of the juice... The device, from the spinning gauze It is preferable to blow the annular cooling device inside the outside hurricane, and it is particularly preferable that the outer-ring type annular cooling device is better. In particular, according to one of the preferred examples of the method of the first embodiment of the present invention, the first embodiment of the present invention is based on the first embodiment and the first embodiment of the present invention. FIG. 1 is a schematic view showing an example of a manufacturing process of a ring-shaped stroke. The first embodiment is an example of a manufacturing process in which the annular type cold portion=part device 3 is used. In the following description, the basic configuration of the first drawing and the second f is the same, and the description of the common symbol is omitted. 201231746 In the first drawing, the melted polyamine is discharged from the nozzle i, and after the lower holding zone 2, the length is lowered. For the purpose of unevenness in the direction of the fineness, the cooling type air is blown from the inner side of the access sliver to the outside by the blow-type annular cooling device 3 disposed below the center of the pout, so that each single yarn is uniform from the nozzle surface. The distance is rapidly cooled and solidified. In the step of integrating the yarns into the bundle, the disc-shaped guide portion that contacts the single yarn at the outer periphery of the BJ disc, and the oil-discharge for forming the outer periphery of the guide portion directly above the guide portion The annular oil supply device 4 of the annular slit, whereby the oil is supplied to each of the single noisy, and the yarn is gathered in the bundle-guided oil supply device 5 to perform the second stage of oil supply. After the oil supply, it is necessary to interlace the staggered nozzles 6 and wind up by pulling the pro- 7 and stretching the light 8' by a winder (winding device) 9. Moreover, it is a fiber long fiber and (1) a fiber product package. Further, before being wound into a package, it can be stretched by two or more groups. In this case, the cross-over is caused by the stretching, so that the stretching ratio can be lowered or stretched and then given again. Interlaced. In the nozzle lower holding zone 2, the vapor is sprayed toward the mouth surface and the nozzle holding area 2 is filled with steam, and the polymer around the discharge port of the nozzle is gathered. The oligomer contained in the substance is reacted with oxygen to be solidified, and the effect of suppressing so-called nozzle contamination is applied. At this time, the discharge pressure of the steam should be 〇1 to 〇5 kPa, the discharge pressure is too small, the oxygen concentration in the heat preservation zone under the nozzle is high, and the suppression effect of the nozzle surface contamination is small, and when the discharge pressure is too large, it may be caused. The swing of the spit is spit out, thus affecting the deterioration of the Uster unevenness. : When the spun yarns arranged on the circumference of the circle are cooled, the ring-shaped crotch device is used to spray the cooling air into the outer gauze, which can be spit from the nozzle at-10-201231746. The oligomer component or gas produced by the amine is not retained in the inside of the spinning device and is opened to the outside, so it is suitable. '·· In the manufacturing step of the above-mentioned figure, the outer-blow type annular cooling device 3 is used, but the inner-blow type annular cooling device 18 shown in Fig. 5 may be used instead of the outer-blown ring. Type cooling device 3. The inner-blow type annular cooling device 18 is placed under the center of the nozzle so as to surround the spun yarn, and the cooling air is blown from the outer side of the spun yarn to the inner side so that each single yarn is from the nozzle surface. The uniform distance is rapidly cooled and solidified. The distance from the cooling starting point is 胄, that is, the distance from the nozzle face to the upper end of the cooling air blowing portion in the annular cooling device (1〇 to 1〇 to 7〇 is preferably 10 to 60mm is better) to 1〇 When the distance between the cooling start points is too short, the cooling air blown from the annular cooling device is near the nozzle surface. The temperature of the nozzle surface is lowered to deteriorate the discharge stability of the thermoplastic polymer. The spinning gauze is broken or the fluff is increased. Moreover, when the cooling starting point distance is too long, the long-direction fineness of the fiber is justified by the uniformity and rapid cooling of the cooling wind. The variation (Uster unevenness) tends to become large, and the texture tends to decrease when the fabric is formed. The wind speed of the cooling air in the cooling device is preferably 15 to 60 m / 20 to 55 m/min. It is better to use 25 to 50 m/min. The cooling wind speed is too small 'because the uniformity of the single yarn and the rapid cooling become insufficient or the cooling town>, the extension of the strip is too small, so the yarn is easily shaken due to interference. Uster unevenness increases, and the cooling of the polymer is insufficient In the case of guiding 4 contact, the fluff or the yarn breakage frequently occurs, so the texture is deteriorated when the fabric is formed. When the cooling wind speed is too large, the yarn is slightly vibrated by applying tension to each of the -11-201231746 single yarns. The unevenness of the sinter and the breakage of the yarn during spinning. The temperature of the cooling air in the annular cooling device is preferably 5 to 50 ° C, preferably 10 to 40 ° C, and 15 to 35 ° C. More preferably, when the temperature of the cooling air is too low, the temperature of the holding area under the nozzle is lowered, and the temperature of the nozzle surface is lowered, so that the strength of the sliver is lowered. When the temperature of the cooling air is too high, it is difficult to uniformly cool the sliver. Moreover, the cooling of the sliver is insufficient, and in addition to the increase in Uster unevenness, there is a tendency to increase the yarn breakage during spinning. The length of the vertical direction of the cooling air blowing portion in the annular cooling device And 100 to 500 mm' is preferably 150 to 400 mm, more preferably 200 to 350 mm. When the cooling air blowing length is too long, the tension applied to the single yarn is increased, causing the spinning to break, and the cooling wind blowing length. When it is too short, it is given due to insufficient cooling of the single yarn. The oil agent causes the fluff reduction and the yarn breakage. The spun yarn running on the annular oil supply device can pass through the single yarn of the annular cooling device. The annular oil supply device is arranged in the circumference. Fig. 4 is a conceptual view showing a ring-shaped oil supply device to which the present invention is applied. The annular oil supply interspersed 4 has an oily spitting and a disc-shaped guide portion 13. The slit 1 2 single yarn) 14 is in contact with the disc-shaped guide A long fiber (the guide portion 13 is arranged in a ring shape. The contact point is supplied to the contact point of the sliver in the disc type guide 4 1 3 In the manner of the oil agent, the oil discharge opening slit 12 is formed on the outer circumference of the disk-shaped guide portion 13 along the circle I, J.

The second of the two The friction between the part and the single yarn that is not given the oil agent, and the occurrence of the stain on the octagonal guide, since the high drop, the raw and the dyeing can be obtained, and the position of the oil agent is given to the mouth by the annular oil supply device: Below _ to H) below 00mm '35 〇 to the bottom of the Hong Kong is better below 40 〇 to 6 〇〇 mm. Sand &,,,,,,,,,,,,,,,,,,, In the state where the cold part of the crucible is insufficient, and directly in the early reduction and the silk "" directly to the oil agent, causing the strength of the long fiber = the generation of hair, when the oil supply position is too low, except that the ancient heart carving is only long, Therefore, the airflow effect accompanying the oscillating yarn which is easy to cause the yarn is increased, and the tension of the running yarn is increased by the military height and the red color, and the tension of the yarn is increased by a special π: the type of the oil agent given in the annular oil supply device and the profitability Limit 1 is better in gel type. In gel oil, due to surface tension; -13- 201231746 and 5^ paragraphs, although the oil is used for the oil, it is produced by The guide portion is easily oriented, and the m & phase (4) is applied to the oil along the ® (four) guide portion. After the single yarn gathers the oil, the side of the oil supply mode of the bundle-guided oil supply device, the present and the bundle, further adopts the two sides of the oil supply to achieve the m, because it can be between the single yarn and the long direction of the fiber. It can be uniformly used in a single yarn. Therefore, it can be applied to the oil supply device 4 in the annular oil supply device 4, but it is difficult to obtain the enthalpy of the long direction.

A good-quality polyamine fine fiber after the h color is applied - the bundle-guided oil supply device used in the two-stage oil supply can supply the oil guiding portion. For example, it can be applied as shown in the above Patent Document 3. : The pulling speed of the sliver in the take-up roller 7 is preferably 35 〇〇 to the side claw/min ~, and when the taking speed is too low, the orientation of the stalk 4 in the long direction does not change: the smear in the long direction is easy Occurs when the pulling speed is too high: the tension of the two increases, thus causing the fluff and the spinning to break.

The two & k are too low, and the single yarn breaks and the villi are easily produced. The polyamine fine fiber of the present invention needs to be a single yarn fineness in the 〇ι- For those below X, 0 25dtexi 〇...(4) is preferred. When the single yarn is used, the rigidity of the sliver becomes high. When the braid is formed, it is difficult to obtain a knitted fabric excellent in flexibility, smoothness, drapability, high water absorbability, and high density as expected from -14 to 201231746. When the fineness of the yarn is too fine, the single yarn is liable to break when the fabric is formed, and there is a tendency that the fabric is fluffed or the smoothness is inferior and the texture of the fabric tends to deteriorate after dyeing due to the increase in the unevenness of the Uster. The determination of the single yarn fineness of the domain is based on the following. The polyaniline ultrafine fiber of the present invention is required to have a lower average number of fluffs of the long fiber of the long ray. When the average number of piles is small, there will be a lack of smoothness and texture when there is a generation of warp fluff or a knit fabric is added during the weaving. The average value of UOOOm is longer in the direction of the leader, and 0 is better. In order to reduce the friction, it is preferable to prevent the T'1 between the single yarns having high frictional resistance before the oil repellent agent from being supplied to the oil by the above-mentioned annular oil supply guide portion. On the order of Cheng Cheng, to the first party to the method. The measurement of the number of the average number of piles is based on the change of the sliverness of the yarn in the longitudinal direction of the thick t 2 of the sliver described later. The dyeing tends to become denser when dyed, especially in the uniformity of the single yarn. If the unevenness is large, the 'weaving' is 1,0%, and the view is 'weave'. Therefore, the unevenness (the thickness difference when the thickness is uneven) is large when the V 3 Uster unevenness is too high. Smoothness and dyeing are not related to calving, and there is a tendency for the texture of the product to be inferior. Ub 5 degree is not particularly limited to 〇9〇/〇1. For the method of reducing the unevenness, the method of rapid cooling, The method of blowing the cooling air blowing device close to the nozzle surface and blowing the gauze from the outer circumference and/or the inner circumference to cool the unloading 201231746 wind is applicable. More preferably, it is used: from the inner circumference of the gauze A method of blowing a ring-shaped cooling air to uniformly cool a single yarn, and then bringing each single yarn into contact with a disk-shaped guide portion to prevent the yarn from swinging. In the present invention, Uster unevenness (thickness is not The measurement of the degree of uniformity is based on the method described later. The polyamine fine fiber of the present invention contains a cross-sectional shape of a circle. In the case of a single yarn, it is preferable that the orientation parameter of the surface portion is different from the parameter of the central portion in the single yarn. When the orientation parameter of the surface portion is different from that of the central portion, the center of the fine fiber of the polyamide is passed. The refractive index of the light is different from that of the surface portion, and the anti-transparation effect can be obtained even if it is a circular cross-section. Specifically, the ratio of the orientation parameter of the surface portion of the single yarn to the orientation parameter of the central portion of the single yarn is 1.10 or more, and 1.15. More than 2 times the number of times or less is preferably 丨2〇 or more and 1.80 times or less. Relative to the orientation parameter of the central portion of the single yarn, when the parameter of the surface port ρ is in the above range, due to the single yarn The light in the direction of the surface is diffusely reflected, so that the fabric can be made transparent and the deformation in the internal structure of the fiber is not excessive. 2 The sufficient long fiber strength is maintained. The method of setting the method. The polystyrene fiber with the parameters of the dip, the horse does not make the cooling starting point away from the vortex η, the carving is too long and the wind speed of the cooling wind (cold I7 wind speed) is too small. By choosing The best conditions for the production of the ground are obtained by the "fine yarn of the snails of the snails, and the fibers of the melt-spun yarn can be obtained by the yarns of the above-mentioned surface portions, by the conditions of the harvesting' The orientation of the surface of the single yarn maintains a very thin single yarn strip 岣 - and in the case of rapid cooling, the orientation parameter to the parameter and the central portion is used for the orientation parameter of the central part of the single yarn with the cooling parameter which can be cooled more quickly and uniformly. The ratio of the number of 201231746 has an increasing tendency. The elongation of the fine fiber of the polystyrene is preferably from 4 〇 to 70%. When the elongation is too low, the tensile strength of the long fiber is increased, and the false twist is processed. The number of real turns is reduced, so it is difficult to impart sufficient crimping to the obtained processed yarn, and in the drawn yarn, yarn breakage and pile are likely to occur, and high-order stretches are made to the 'other' through the inferior employee. When the crucible is excessive, the actual number of false twists is excessive, and the obtained processed yarn is liable to fluff and the strength is lowered. In the drawn yarn, the residual stretch is high, and streaks are easily formed in the knitted fabric.

The above-mentioned elongation is measured in accordance with the method D described later, and the stress at which the obtained polyamine fine fiber is elongated by 5% is preferably 1.0 to 2.0 gf/dtex (9 8 < 1 〇 -3 to 19 6 x 〇 _3N/dtex), preferably i 2 to i.8gf/dtex (11.8xm 17 6xl0-3N/dtex). When the stress at the time of elongation (4) is too low, the tension at the time of the false twisting process becomes too low, the processed yarn is broken, or the processing tension is liable to change. The texture of the processed yarn is lowered or the yield is easily deteriorated. And when the stress at the time of elongation of 15% is too high, in the case of the meal technique: processing k, the father's wrong part has a large tension concentration and a single yarn breakage occurs. It is easy to reduce the texture of the steps or the texture of the braid. The measurement of the stress at the time of elongation of 1 53⁄4 is based on the method described later. The total fineness of the polyamine fine fibers of the present invention is preferably 丨5 to 3 〇〇 dt... preferably 15 to 200 dtex. The total fineness is over the Xiaoji Temple, the fiber breaks the j, and the tear strength of the fabric becomes smaller when the fabric is made. When the total fiber is too large, the dye is difficult to penetrate into the fiber during dyeing, and the dyeing is easy to produce stains. It is difficult to obtain a fabric with high texture. The measurement of the above total fineness is based on the method described later. -17- 201231746 When the polyfluorene 30 to 500 filaments of the present invention are excellent, it is difficult to obtain water-based, high-density properties, and it is easy to make the unwinding property difficult, and it is easy to increase the polyfluorene of the present invention, and examples thereof include: Shape: flat section, the lens is called the section of the multi-concave section, the circular section of the hollow section, which is excellent in the structure of the central portion and the surface portion at the point of the sagability and passes through and 'because of the three-leaf single yarn The light of the surface is diffused and reflected by the light, and the three-leaf section, the long-fiber-mixed section to the high void, is caused by the high bulk density reflection, and the anti-permeability of the amine-coated ultrafine fiber is 50 to When the number of the soft long filaments which are excellent in the target of the long fiber is too large, it is difficult to make a cross section and a profiled section of the fine polyester fiber of the single yarn which is broken between the long fibers. The profiled section and the trilobal section have 3 to 8 projections and other conventional profiled sections to impart stability to the spinning. Further, since the polyamine has the cross section in the cross-sectional direction of the preferred oriented single yarn and the diffuse reflection of the multi-concave profile, the barrier property can be obtained, and the embossed portion can be formed into a capillary tube by a concave-convex cross-section or a multi-concave structure. The high point of the phenomenon is excellent, and it is better, and therefore the applicable number is preferably more than 30%. The number of long fibers is less than 30, drapability, and high absorption uniformly imparting hair imparting to the interlaced uniform oil. The shape is not particularly limited. The profiled section may be, for example, a six-leaf profile, that is, a profiled surface of the same number of recesses. The preferred cross-section is excellent in flexibility, when the ratio of the suspended fiber to the circular profile parameter is diffusely reflected by the fixed light, and when the hollow profile is formed into a woven fabric, it is preferable. When the profile is more convex and circular, the water absorption between the single yarns can be obtained, and the light can be imparted, and the light is transmitted through the light----------------------------------------- Sex, high water absorption, Guliufu meat selection, degree -18- 201231746 Sexually different m ^ ^ ~ core 俅 Y, impermeability is also m ” Therefore, the ultrafine fiber of the present invention can be suitable for heat preservation when fabricating a fabric The woven fabric of the fabric of the feather jacket, which is excellent in the nature and the lightness, and the like, and the lining of the high-quality sensation of the above-mentioned functions, and the covering yarn used for the underwear or the like, can be applied to the woven fabric. EXAMPLES Hereinafter, the present invention will be described in more detail based on examples.

The value obtained by dividing the total fineness obtained by the number of single yarns of the yarn as the single yarn fineness (i) of 27 dtex or less: Total fineness (dtex) = measurement value (g) x (10000/1000) x {1 + Moisture rate (%)/100)} (i) Variety below 28 dtex: Total fineness (dtex) = measurement value (g) x (i〇〇〇〇/5〇〇) x {l+ (nominal moisture content (%) /100)} In the case of the nylon 6 and nylon 66 polymers used in the examples, the specific moisture content was set to 4.5% to calculate the fineness. Single yarn fineness (dtex) = total fineness (dtex) / Single yarn number -19- 201231746 However, for two different types: single yarn fineness in the mixed filament of the e-town 丄~ shape (section A and section B), is in the single cross-sectional shape of The surface of the yarn section is C, ^, 'multiply the total fineness by the area ratio, and then divide by the total number of long fibers of the same shape. The area ratio of the fruit section = Α Α &" B Area) area of one side A/(area of section A, area ratio of surface section B = area of section B, area of section B of section a) j Single yarn of section A of the mixed fiber long fiber. tj Early heart fineness (dtex ) = (area ratio of total fineness (eX) X section A) / section A of long fiber count of single-fiber fineness (dtex) of section B in mixed filaments = (total fineness (dteX) x area ratio of section B) /Fiber number of section 3 (2) Relative viscosity of sulfuric acid The δ-type material obtained by weighing is dissolved in 98% by weight of concentrated sulfuric acid to make the concentration of the sample lg/100 ml, for the solution 'with Oswald's viscosity meter (〇stwald Viscometer) measured 25t: the number of seconds of landing (τι) β further 'for 98% by weight of concentrated sulfuric acid in the undissolved sample, and similarly measured the number of seconds of fall (T2) in 25〇c Relative viscosity (ηΓ).
