Description

由自膨化性含PTT之雙組分纖維製成的地毯Carpets made of self-expanding bicomponent fibers containing PTT

本揭露關於地毯,並且更具體地關於面纖維包含自膨化性含聚(對苯二甲酸丙二酯)(PTT)的雙組分纖維的地毯。The present disclosure relates to carpets, and more specifically to carpets in which the face fiber contains a self-expandable bicomponent fiber containing poly(trimethylene terephthalate) (PTT).

在現代地毯的製造中,通常使用合成聚合物(例如尼龍、聚酯、聚丙烯)來製備具有高水平膨化度的纖維,該高水平膨化度可被定義為與未膨化的或「扁平」纖維相比,纖維的覆蓋能力或表觀體積增強。該等膨化連續纖維(「BCF」)典型地是在紡絲機上製造的單組分纖維,該紡絲機具有專門設計成以機械方式對纖維賦予膨化度的高溫/高壓射流和冷卻圓筒。此製程有幾個缺點。射流中纖維的高溫、高壓和湍流可能損壞纖維長絲,並對纖維的物理特性產生不利影響。此外,與不需要機械膨化的其他紡絲製程(即全拉伸紗線(「FDY」)或部分取向紗線(「POY」)扁平紗線)相比,對藉由射流/圓筒製程賦予膨化度的需求需要降低纖維生產速度。In the manufacture of modern carpets, synthetic polymers (such as nylon, polyester, polypropylene) are usually used to prepare fibers with a high level of expansion, which can be defined as the difference between unexpanded or "flat" fibers. In contrast, the covering capacity or apparent volume of the fiber is enhanced. The bulked continuous fibers ("BCF") are typically monocomponent fibers manufactured on a spinning machine with a high temperature/high pressure jet and cooling cylinder specifically designed to mechanically impart bulkiness to the fiber . There are several disadvantages to this process. The high temperature, high pressure and turbulence of the fibers in the jet may damage the fiber filaments and adversely affect the physical properties of the fibers. In addition, compared with other spinning processes that do not require mechanical expansion (ie, fully drawn yarns ("FDY") or partially oriented yarns ("POY") flat yarns), the jet/cylinder process gives The demand for bulkiness requires a reduction in fiber production speed.

表徵紡織纖維的一種方式係藉由它們的捲曲量。「捲曲」係指纖維的波紋度,並且可以表示為捲曲數量/單位長度。捲曲量,本文中也稱為「捲曲收縮率」,可以藉由比較纖維在負載下的伸展長度與纖維在無負載情況下的縮回長度來表示。纖維中的捲曲量可以是自然發生的(例如羊毛),或在製造中賦予給合成纖維以適應所希望的最終用途。可以藉由以下方式產生捲曲:使用膨化射流(BCF)中的空氣和熱量,在假撚變形機上對POY進行加撚/解撚以製成拉伸變形紗線(DTY),或藉由並列或偏心皮/芯雙組分纖維的異收縮。低水平的捲曲對應於具有改善的鬆軟度或膨化度的紡織纖維,並且當織物的不透明度或覆蓋度很重要時,這係理想的。可替代地,高水平的捲曲導致纖維具有顯著水平之拉伸和恢復,並且在服裝應用中很有價值。One way to characterize textile fibers is by their amount of crimp. "Crimp" refers to the waviness of the fiber, and can be expressed as the number of crimps/unit length. The amount of crimp, also referred to herein as "crimp shrinkage", can be expressed by comparing the stretched length of the fiber under load with the retracted length of the fiber under no load. The amount of crimp in the fiber can be naturally occurring (e.g. wool) or imparted to synthetic fibers during manufacture to suit the desired end use. The crimp can be produced by the following methods: using the air and heat in the bulking jet (BCF) to twist/untwist the POY on a false twist texturing machine to make a stretch texturized yarn (DTY), or by paralleling Or different shrinkage of eccentric sheath/core bicomponent fiber. Low levels of crimp correspond to textile fibers with improved softness or bulkiness, and this is ideal when the opacity or coverage of the fabric is important. Alternatively, a high level of crimping results in a significant level of stretching and recovery of the fiber, and is valuable in apparel applications.

在地毯應用中,較低水平的捲曲對於在沒有明顯的拉伸展現的情況下賦予高膨化度係理想的。用於織物的包含雙組分長絲的自捲曲性高膨化度紗線描述於美國專利案號7,790,282中。在服裝織物中,並列型和偏心皮/芯型雙組分纖維捲曲特性典型地被最大化,以在纖維和所得織物中提供高水平的拉伸。2004年10月12日授予Talley等人的美國專利案號6,803,102 B1係生產具有不對稱纖維橫截面的雙組分纖維的示例,並以其全文併入本文。In carpet applications, a lower level of curl is ideal for imparting a high degree of bulk without significant stretch development. A self-crimping high bulking yarn containing bicomponent filaments for use in fabrics is described in US Patent No. 7,790,282. In apparel fabrics, side-by-side and eccentric sheath/core bicomponent fiber crimp characteristics are typically maximized to provide a high level of stretch in the fiber and the resulting fabric. US Patent No. 6,803,102 B1 issued to Talley et al. on October 12, 2004 is an example of the production of bicomponent fibers with asymmetric fiber cross-sections, and is incorporated herein in its entirety.

2000年12月12日授予Talley等人的美國專利案號6,158,204揭露了一種由雙組分纖維製成的自定型紗線,該雙組分纖維形成鎖定撚度並形成膨化度的螺旋捲曲。還揭露了在地毯和紡織品中使用此種紗線。揭露了多種聚合物,諸如聚(對苯二甲酸乙二酯)(「PET」)、聚(對苯二甲酸丁二酯)(「PBT」)、聚丙烯、尼龍等。然而,未揭露聚(對苯二甲酸丙二酯)(PTT)之用途。U.S. Patent No. 6,158,204 issued to Talley et al. on December 12, 2000 discloses a self-setting yarn made of bicomponent fibers that form a spiral crimp that locks in twists and forms bulkiness. The use of such yarns in carpets and textiles is also disclosed. A variety of polymers were exposed, such as poly(ethylene terephthalate) ("PET"), poly(butylene terephthalate) ("PBT"), polypropylene, nylon, etc. However, the use of poly(trimethylene terephthalate) (PTT) is not disclosed.

聚(對苯二甲酸乙二酯)(PET)均聚物或聚(對苯二甲酸乙二酯)共聚物(co-PET)的一種組分以及聚(對苯二甲酸丙二酯)(PTT)或PTT與PET均聚物或PET共聚物(co-PET)的共混物的第二組分,該方法包括: a)  在能夠產生兩個或更多個獨立熔體流的紡絲機上擠出兩種組分; b) 在適合製備雙組分纖維的噴絲板中合併熔體流; c)  在空氣中淬火步驟 (b) 中產生的自膨化性雙組分纖維; d) 對自膨化性雙組分纖維進行拉伸和熱定型;以及 e)  藉由適合的手段捲繞自膨化性雙組分纖維以用於後續加工成地毯, 其中自膨化性雙組分纖維消除了對機械膨化步驟的需要。A component of poly(ethylene terephthalate) (PET) homopolymer or poly(ethylene terephthalate) copolymer (co-PET) and poly(trimethylene terephthalate) ( PTT) or the second component of the blend of PTT and PET homopolymer or PET copolymer (co-PET), the method includes: a) Extruding two components on a spinning machine capable of producing two or more independent melt streams; b) Combine the melt flow in a spinneret suitable for the preparation of bicomponent fibers; c) Self-expandable bicomponent fibers produced in the air quenching step (b); d) Stretching and heat setting the self-expanding bicomponent fiber; and e) Winding self-expanding bicomponent fibers by suitable means for subsequent processing into carpets, Among them, the self-expanding bicomponent fiber eliminates the need for a mechanical expansion step.

本文所述之雙組分纖維可以是並列(「S/S」)或偏心皮芯(「S/C」)構型。雙組分纖維可以藉由使用每種形狀特定的噴絲板製成各種橫截面形狀,例如圓形、三角形、三葉形、扇形或其他形狀,例如,如美國專利案號6,803,102所揭露的,其藉由引用以其全文併入本文。The bicomponent fibers described herein can be in side-by-side ("S/S") or eccentric sheath-core ("S/C") configurations. Bicomponent fibers can be made into various cross-sectional shapes, such as circular, triangular, trilobal, fan-shaped or other shapes by using spinnerets with specific shapes for each shape. For example, as disclosed in US Patent No. 6,803,102, It is incorporated herein in its entirety by reference.

典型地,用於地毯的纖維係在製造方法中經受機械膨化步驟的單組分纖維。相比之下,本文所述之其面纖維包含自膨化性連續纖維,該纖維包含含有聚(對苯二甲酸丙二酯)的雙組分纖維的地毯由於異收縮而為自膨化性的。Typically, the fibers used for carpets are monocomponent fibers that undergo a mechanical expansion step in the manufacturing process. In contrast, the surface fibers described herein include self-expandable continuous fibers, and carpets containing bicomponent fibers containing poly(trimethylene terephthalate) are self-expandable due to heterogeneous shrinkage.

如上所述,自膨化性雙組分纖維的組分中的一種係PTT或PTT與PET或與co-PET的共混物。由於PTT與其他可商購獲得的聚酯相比具有獨特的收縮特性,因此PTT可以非常有效地提供捲曲。自膨化性雙組分纖維的另一組分係PET或co-PET,並且由於其收縮與PTT相比係最小的,所以此組分組合允許最大的收縮差異,並因此允許捲曲展現。相比之下,聚(對苯二甲酸丁二酯)(PBT)較不適合作為與PTT或PTT/PET共混物一起使用以製備自膨化性雙組分纖維的組分,因為PBT、PTT和PTT/PET共混物將顯著收縮,從而導致兩種組分之間的異收縮較低,並因此所得雙組分纖維的捲曲展現也較低。例如,在並列或偏心皮/芯自膨化性雙組分纖維中的聚合物重量比相等時,包含PTT和PET作為兩種組分的雙組分纖維將比包含PBT和PET作為兩種組分的雙組分纖維或包含各自具有不同的特性黏度(IV)的兩種不同的PET作為兩種組分的雙組分纖維提供更高的膨化度。As mentioned above, one of the components of the self-expandable bicomponent fiber is PTT or a blend of PTT and PET or co-PET. Since PTT has unique shrinkage characteristics compared to other commercially available polyesters, PTT can provide crimp very effectively. The other component of the self-expandable bicomponent fiber is PET or co-PET, and since its shrinkage is the smallest compared to PTT, this component combination allows the largest shrinkage difference, and thus allows crimp to develop. In contrast, poly(butylene terephthalate) (PBT) is less suitable as a component for use with PTT or PTT/PET blends to prepare self-expandable bicomponent fibers, because PBT, PTT and The PTT/PET blend will shrink significantly, resulting in lower iso-shrinkage between the two components, and therefore the resulting bicomponent fiber exhibits lower crimp. For example, when the weight ratio of polymers in the side-by-side or eccentric sheath/core self-expandable bicomponent fiber is equal, the bicomponent fiber containing PTT and PET as the two components will be higher than the bicomponent fiber containing PBT and PET as the two components. A bicomponent fiber or a bicomponent fiber containing two different PETs each with a different intrinsic viscosity (IV) as the two components provide a higher degree of expansion.

尼龍聚合物,包括尼龍6和尼龍66,也可以用作自膨化性雙組分纖維的第一組分;然而,尼龍聚合物通常與作為第二組分的聚酯沒有足夠的黏附性,並且當受到應力時可能***和裂開。因此,包含尼龍和聚酯的雙組分纖維可能不是地毯紗線的最佳選擇。Nylon polymers, including nylon 6 and nylon 66, can also be used as the first component of self-expandable bicomponent fibers; however, nylon polymers generally do not have sufficient adhesion to the polyester as the second component, and It may split and split when subjected to stress. Therefore, bicomponent fibers containing nylon and polyester may not be the best choice for carpet yarns.

雙組分PET或co-PET以及PTT或PTT與PET或coPET的共混物,可以以80 : 20至20 : 80的重量比存在於自膨化性雙組分纖維中。例如,第一組分和第二組分的重量比可以是80 : 20、75 : 25、70 : 30、65 : 35、60 : 40、55 : 45、50 : 50、45 : 55、40 : 60、35 : 65、30 : 70、25 : 75、20 : 80,或在此範圍內的任何比率。在一個實施方式中,第一組分和第二組分的重量比為約50 : 50。The bicomponent PET or co-PET and the blend of PTT or PTT and PET or coPET can be present in the self-expanding bicomponent fiber in a weight ratio of 80:20 to 20:80. For example, the weight ratio of the first component and the second component may be 80: 20, 75: 25, 70: 30, 65: 35, 60: 40, 55: 45, 50: 50, 45: 55, 40: 60, 35: 65, 30: 70, 25: 75, 20: 80, or any ratio within this range. In one embodiment, the weight ratio of the first component to the second component is about 50:50.

為了用於地毯,自膨化性雙組分纖維具有30%或更低的加熱後捲曲收縮率值。加熱後捲曲收縮率可以藉由下面實例部分中揭露的捲曲收縮率方法來測量。存在幾種方式可以調整雙組分纖維的兩種組分,以實現所得雙組分纖維中30%或更低的所希望的加熱後捲曲收縮率。一種選擇係調整每種組分相對於另一組分的聚合物特性黏度(IV)。例如,如果雙組分纖維的兩種組分之間的IV差很大,這兩種組分之間就會發生高水平的異收縮,從而導致不適合製備地毯的高捲曲值和纖維拉伸特性。相比之下,如果兩種組分之間的IV差太小,這兩種組分之間就不會發生實質性的收縮差異,從而導致幾乎沒有膨化度。For use in carpets, self-expandable bicomponent fibers have a value of 30% or lower crimp shrinkage after heating. The crimp shrinkage after heating can be measured by the crimp shrinkage method disclosed in the example section below. There are several ways to adjust the two components of the bicomponent fiber to achieve the desired crimp shrinkage after heating of 30% or less in the resulting bicomponent fiber. One option is to adjust the intrinsic viscosity (IV) of the polymer of each component relative to the other component. For example, if the IV difference between the two components of a bicomponent fiber is large, a high level of heterogeneous shrinkage will occur between the two components, resulting in high crimp values and fiber tensile properties that are not suitable for making carpets. . In contrast, if the IV difference between the two components is too small, there will be no substantial difference in shrinkage between the two components, resulting in almost no degree of expansion.

生產具有較佳的捲曲水平的雙組分纖維的另一種方式係改變兩種組分的重量比。如果雙組分纖維含有顯著比例的PTT,則所得纖維可以具有高捲曲值和纖維拉伸。相反,體積比中極低量的PTT可能不會提供足夠的膨化度或加熱後捲曲收縮率以實現所希望的水平。Another way to produce bicomponent fibers with better crimp levels is to vary the weight ratio of the two components. If the bicomponent fiber contains a significant proportion of PTT, the resulting fiber can have high crimp values and fiber stretch. Conversely, a very low amount of PTT in the volume ratio may not provide sufficient expansion or curl shrinkage after heating to achieve the desired level.

生產具有較佳的捲曲水平的雙組分纖維的第三種方式係以固定比(例如PTT和PET的50/50重量比)使用PET/PTT共混物作為一種組分,並且PET作為第二組分。已發現,在一種組分中將PET與PTT共混可以用於單獨改善PTT的高收縮特性。當用包含PTT和PET共混物的一種組分並且第二組分係PET來製造雙組分時,則可以製備具有相等重量比(例如,50/50 w/w組分1與組分2)的纖維,以提供所希望的捲曲水平,即30%或更低的加熱後捲曲收縮率。在一些噴絲板設計中,可能需要製備具有重量比幾乎相等的兩種組分的雙組分纖維,而將PET與PTT共混係實現此結果的一種方式。The third way to produce bicomponent fibers with better crimp levels is to use PET/PTT blends as one component at a fixed ratio (for example, a 50/50 weight ratio of PTT and PET), and PET as the second component. Components. It has been found that blending PET and PTT in one component can be used to improve the high shrinkage characteristics of PTT alone. When using one component of a blend of PTT and PET and the second component is PET to make two components, it can be prepared with an equal weight ratio (for example, 50/50 w/w component 1 and component 2 ) To provide the desired crimp level, that is, 30% or less crimp shrinkage after heating. In some spinneret designs, it may be necessary to prepare bicomponent fibers with almost equal weight ratios of two components, and blending PET and PTT is a way to achieve this result.

可替代地,如本文揭露之有用的雙組分纖維可以藉由改變其中第二組分係PET或co-PET的雙組分纖維的一種組分中PTT/PET共混物的組成來製備。此方法可以用於製備其中可能需要高水平的PET的有用的雙組分纖維。綜上所述,改變聚合物類型、IV、重量比和共混物組成係全部技術,藉由該等技術可以設計自膨化性雙組分纖維,以達到導致產生所希望的地毯膨化度的目標捲曲值。在纖維生產期間改變輥和/或捲繞機的相對速度也可能影響捲曲收縮率。Alternatively, the useful bicomponent fiber as disclosed herein can be prepared by changing the composition of the PTT/PET blend in one component of the bicomponent fiber in which the second component is PET or co-PET. This method can be used to make useful bicomponent fibers where high levels of PET may be required. In summary, changing the polymer type, IV, weight ratio, and blend composition are all technologies. With these technologies, self-expandable bicomponent fibers can be designed to achieve the goal of producing the desired degree of carpet expansion. Curl value. Changing the relative speed of the roll and/or winder during fiber production may also affect the crimp shrinkage.

本文揭露之自膨化性雙組分纖維中PTT的一個好處係與PET相比,它提供了高水平的收縮。相對少量的PTT可以用作自膨化性雙組分纖維的一種組分,以產生具有所希望的膨化度的雙組分纖維。然而,雙組分纖維中太高水平的PTT內含物可能導致拉伸水平過高而不可用於地毯紗線並且將更適合服裝用途。One of the benefits of PTT in self-expandable bicomponent fibers disclosed in this article is that it provides a high level of shrinkage compared to PET. A relatively small amount of PTT can be used as a component of the self-expandable bicomponent fiber to produce a bicomponent fiber with the desired degree of expansion. However, too high levels of PTT inclusions in bicomponent fibers may result in excessive stretch levels that are not usable for carpet yarns and will be more suitable for apparel applications.

纖維可以藉由將聚合物以所希望的體積或重量比遞送到噴絲板而製成。雖然可以使用任何常規的多組分紡絲技術,但是用於製備雙組分纖維的示例性紡絲設備和方法描述於Hills的美國專利案號5,162,074中。Fibers can be made by delivering polymers to a spinneret in a desired volume or weight ratio. Although any conventional multicomponent spinning technique can be used, exemplary spinning equipment and methods for preparing bicomponent fibers are described in Hills, U.S. Patent No. 5,162,074.

本文揭露之自膨化性雙組分纖維可以與用於製備地毯的所有其他類型的合成和天然的纖維一起使用。地毯可以藉由機械或手工簇絨化、機織和手工打結製成。實例包括1) 寬幅地毯(也稱為全屋地毯),其中簇絨地毯係以幾米寬的長的連續長度製成的,用於家庭和商業應用;2) 拼塊地毯,其以各種尺寸的正方形生產,以便於安裝;3) 家用小地毯;以及4) 用於車輛和建築物入口的墊子,其設計成在進入建築物之前捕獲腳下泥土。The self-expandable bicomponent fibers disclosed herein can be used with all other types of synthetic and natural fibers used to make carpets. Carpets can be made by mechanical or hand tufting, weaving and hand knotting. Examples include 1) wide-width carpets (also called whole-house carpets), where tufted carpets are made in a continuous length of a few meters wide and are used for household and commercial applications; 2) patch carpets, which come in various sizes Are produced in squares for easy installation; 3) household carpets; and 4) mats for vehicle and building entrances, which are designed to capture the soil under the feet before entering the building.

本領域已知的由纖維製備地毯的任何方法都可以用於製備本文所述之地毯。典型地,本文揭露之自膨化性雙組分纖維可以用於使用其他合成纖維和天然纖維的相同地毯製造方法中。雙組分纖維可以自身用於地毯製造(即作為「單股(singles)」紗線),或與更多相同的雙組分纖維或其他纖維類型(例如尼龍、聚丙烯、聚酯)合股在一起以增加旦尼。視需要,單股和合股的纖維可以在合股之前用空氣射流進行纏結,並且也可以藉由專門設計成使單股和簇絨紗線物理特性熱定型的機器進行熱定型。適合此目的的熱定型機的一個實例係由Superba®(米盧斯,法國(Muhouse, France))製造的。無論雙組分纖維係視需要空氣纏結的、合股的還是熱定型的,該等纖維都可以被簇絨化成地毯工業典型的標準非機織或機織的背襯板。可以切斷簇絨地毯中的面纖維環圈以提供割圈地毯。簇絨化後,常常向地毯背面(即與面纖維相反的一側)施加黏合劑,以將簇絨保持在適當位置。也可以將額外的背襯層添加到地毯背面。黏合劑層可以含有填料或阻燃劑,這取決於具體的地毯最終用途。然後,可以藉由地毯製造工業通用的標準製程對地毯進行染色;可替代地,可以在纖維擠出期間向雙組分纖維和/或伴侶纖維中添加顏料,以對成品織物賦予顏色。另外,可以使用被設計成賦予耐火性、抗靜電特性或耐沾汙和泥土性的材料對面紗線進行處理。常常將成品地毯乾燥以除去染色製程中殘留的水。Any method known in the art for preparing carpets from fibers can be used to prepare the carpets described herein. Typically, the self-expandable bicomponent fibers disclosed herein can be used in the same carpet manufacturing method using other synthetic fibers and natural fibers. Bicomponent fibers can be used in carpet manufacturing by themselves (that is, as "singles" yarns), or be combined with more of the same bicomponent fibers or other fiber types (such as nylon, polypropylene, polyester). Together to increase denim. If necessary, single-stranded and plied fibers can be entangled with air jets prior to plying, and can also be heat-set by machines specifically designed to heat-set the physical properties of single-stranded and tufted yarns. An example of a heat setting machine suitable for this purpose is manufactured by Superba® (Muhouse, France). Regardless of whether the bicomponent fibers are air-entangled, stranded or heat-set as required, these fibers can be tufted into standard non-woven or woven backing panels typical of the carpet industry. The face fiber loops in the tufted carpet can be cut to provide a cut loop carpet. After tufting, adhesives are often applied to the back of the carpet (that is, the side opposite to the face fibers) to keep the tufting in place. It is also possible to add an additional backing layer to the back of the carpet. The adhesive layer can contain fillers or flame retardants, depending on the specific end use of the carpet. The carpet can then be dyed by standard processes commonly used in the carpet manufacturing industry; alternatively, pigments can be added to the bicomponent fibers and/or companion fibers during fiber extrusion to impart color to the finished fabric. In addition, the surface yarn can be treated with materials designed to impart fire resistance, antistatic properties, or stain and earth resistance. The finished carpet is often dried to remove residual water from the dyeing process.

上述製造方法係用於寬幅簇絨地毯的典型方法。工業上已知的對此方法的變體可以用於小地毯、拼塊地毯和車用墊子的生產。The above manufacturing method is a typical method used for wide-width tufted carpets. Variants of this method known in the industry can be used in the production of small carpets, carpet tiles and car mats.

本文揭露之雙組分纖維的一個特徵係藉由將纖維的溫度升高到至少75°C但低於200°C來展現捲曲和膨化度。在視需要的熱定型、染色和乾燥步驟期間,雙組分纖維將在地毯生產的標準過程中經受此溫度範圍。可替代地,可以使地毯經受單獨的加熱步驟以展現膨化度,或可以對雙組分纖維(單股或合股的)進行熱處理以展現膨化度。One feature of the bicomponent fiber disclosed herein is that the temperature of the fiber is raised to at least 75°C but less than 200°C to exhibit crimp and bulkiness. During the optional heat setting, dyeing and drying steps, the bicomponent fibers will withstand this temperature range in the standard process of carpet production. Alternatively, the carpet can be subjected to a separate heating step to exhibit the degree of expansion, or the bicomponent fiber (single or ply) can be heat treated to exhibit the degree of expansion.

包含雙組分纖維的面纖維可以具有圓形或非圓形橫截面,諸如三葉形。它應具有等於或低於30%的加熱後捲曲收縮率。The areal fibers containing bicomponent fibers may have a circular or non-circular cross-section, such as a trilobal shape. It should have a curl shrinkage rate equal to or lower than 30% after heating.

本文揭露之地毯的優點係,因為雙組分纖維由於其異收縮而為自膨化性的,所以不需要對用於製備地毯的紗線進行機械膨化。相比之下,由膨體連續單組分長絲製成的地毯紗線將需要機械膨化,因為它不能發生異收縮。換句話講,藉由使用具有異收縮的雙組分纖維來製備地毯,消除了對連續單組分長絲的機械膨化的步驟。The advantage of the carpet disclosed in this article is that because the bicomponent fiber is self-expandable due to its heterogeneous shrinkage, it is not necessary to mechanically expand the yarn used to make the carpet. In contrast, carpet yarns made from bulked continuous monocomponent filaments will need to be mechanically puffed because it cannot undergo abnormal shrinkage. In other words, by using bicomponent fibers with heterogeneous shrinkage to prepare carpets, the step of mechanical expansion of continuous monocomponent filaments is eliminated.

視需要,其面纖維包含本文揭露之自膨化性雙組分纖維的地毯可以進一步包含至少一種額外纖維。該至少一種額外纖維可與自膨化性雙組分纖維合股在一起以增加旦尼(例如),或可在對地毯進行簇絨化時用作額外地毯紗線。該至少一種額外纖維可以選自膨化性的連續長絲(即單組分長絲)、合成短纖維和天然纖維。在一個實施方式中,該至少一種額外纖維係膨化連續長絲,並且該膨化連續長絲包含尼龍、聚丙烯或聚酯。在另一個實施方式中,該至少一種額外纖維係合成短纖維,並且該合成短纖維包含尼龍或聚酯。在另一個實施方式中,該至少一種額外纖維係天然纖維,並且該天然纖維包含毛、絲或棉。If necessary, the carpet whose face fiber includes the self-expandable bicomponent fiber disclosed herein may further include at least one additional fiber. The at least one additional fiber can be plied with the self-expandable bicomponent fiber to increase denier (for example), or can be used as an additional carpet yarn when tufting the carpet. The at least one additional fiber may be selected from the group consisting of bulky continuous filaments (ie, monocomponent filaments), synthetic staple fibers, and natural fibers. In one embodiment, the at least one additional fiber is an expanded continuous filament, and the expanded continuous filament comprises nylon, polypropylene, or polyester.

In another embodiment, the at least one additional fiber is a natural fiber, and the natural fiber includes wool, silk, or cotton.

在準備進行熔體紡絲時,將顆粒在25英吋汞真空和120°C溫度下的真空烘箱中、氮氣下乾燥15小時。將經乾燥的顆粒直接轉移到紡絲機的氮氣吹掃的進料斗。 纖維的製備In preparation for melt spinning, the pellets were dried for 15 hours in a vacuum oven at a temperature of 120°C and a 25-inch mercury vacuum under nitrogen. The dried pellets are directly transferred to the nitrogen-purged feed hopper of the spinning machine. Fiber preparation

將雙組分纖維的兩種組分使用通常適用於並列和偏心皮/芯雙組分纖維的紡絲的製程和設備進行熔體紡絲,例如,如美國專利案號6,641,916 B1、美國專利案號6,803,102和美國專利案號7,615,173 B2中所揭露,該等專利藉由引用併入本文。The two components of bicomponent fibers are melt-spinned using processes and equipment that are generally suitable for spinning side-by-side and eccentric sheath/core bicomponent fibers, for example, such as US Patent No. 6,641,916 B1, and US Patent Cases. It is disclosed in No. 6,803,102 and US Patent No. 7,615,173 B2, which are incorporated herein by reference.

在對實例的雙組分纖維進行紡絲時,將聚合物在一對維爾納和普夫萊德雷爾(Werner & Pfleiderer)共旋轉28 mm雙螺桿擠出機中熔融,該雙螺桿擠出機具有0.5至40磅/小時(0.23至18.1千克/小時)的容量。一台擠出機(本文中稱為East擠出機)用於熔融PET均聚物(0.50 IV和0.64 IV)顆粒,並且第二擠出機(本文中稱為West擠出機)用於熔融1) 單獨的PTT顆粒;2) PTT顆粒和co-PET共聚顆粒的鹽和胡椒(「S&P」)共混物;或3) 混配的PTT/co-PET顆粒。實例中列出了West擠出機、紡絲模組(spinning block)和East擠出機的溫度。每台擠出機向含有凹形噴絲板的紡絲模組進料。所使用的噴絲板係後聚結、並列雙組分噴絲板,其具有排列成圓圈的三十四對毛細管,每對毛細管之間的內角為30度,毛細管直徑為0.64 mm,並且毛細管長度為4.24 mm。When spinning the bicomponent fiber of the example, the polymer was melted in a pair of Werner & Pfleiderer (Werner & Pfleiderer) co-rotating 28 mm twin-screw extruder. The twin-screw extruded The machine has a capacity of 0.5 to 40 pounds/hour (0.23 to 18.1 kg/hour). One extruder (referred to as East extruder in this article) is used to melt PET homopolymer (0.50 IV and 0.64 IV) pellets, and a second extruder (referred to in this article as West extruder) is used for melting 1) Individual PTT particles; 2) Salt and pepper ("S&P") blends of PTT particles and co-PET copolymer particles; or 3) Mixed PTT/co-PET particles. The temperature of the West extruder, spinning block (spinning block) and East extruder are listed in the examples. Each extruder feeds a spinning module containing a concave spinneret. The spinneret used is a two-component spinneret after coalescence and side-by-side, which has thirty-four pairs of capillaries arranged in a circle, the internal angle between each pair of capillaries is 30 degrees, and the capillary diameter is 0.64 mm, and The capillary length is 4.24 mm.

使離開噴絲板的雙組分長絲在標稱上20°C和0.5 mm/s面速度下藉由叉流式淬滅空氣進行冷卻。然後將長絲推進到雙進料輥,該雙進料輥根據拉伸比,以約800至1200米/分鐘運行。在噴絲板與進料輥之間,使用整理劑施塗器向長絲束施塗潤滑劑。為了影響拉伸,典型地將進料輥加熱到70°C。然後將長絲束加速到退火輥,該退火輥根據所希望的拉伸比,以約3000至3600 m/min的速度運行,並且退火輥溫度典型地為170°C。然後將經退火的雙組分纖維推進到在室溫下運行的兩組雙鬆弛(letdown)輥,之後在Barmag SW6 600捲繞機上捲繞。纖維具有雪人(橢園形(oblong))橫截面形狀。實例 1 PTT 特性黏度( IV )的變化 The bicomponent filament leaving the spinneret is cooled by cross-flow quenching air at a nominal 20°C and a surface velocity of 0.5 mm/s. The filaments are then advanced to double feed rolls, which run at about 800 to 1200 meters per minute depending on the draw ratio. Between the spinneret and the feed roller, a finish applicator is used to apply lubricant to the filament bundle. In order to affect the stretching, the feed roll is typically heated to 70°C. The filament bundle is then accelerated to an annealing roll, which runs at a speed of about 3000 to 3600 m/min, depending on the desired draw ratio, and the annealing roll temperature is typically 170°C. The annealed bicomponent fiber was then advanced to two sets of double letdown rolls operating at room temperature before being wound on a Barmag SW6 600 winder. The fiber has a snowman (oblong) cross-sectional shape. Example 1 Change of PTT intrinsic viscosity ( IV)

實例1示出了使用具有不同IV的PTT顆粒來生產具有所希望的加熱後捲曲收縮率(CCa)值的雙組分纖維。用於製備纖維的PTT顆粒的IV為1.25 dl/g (1a) 或1.02 dl/g (1b)。兩種情況下PET顆粒的IV都為0.64 dl/g。對於每個實例,PTT與PET的重量比為50/50。實例1-a係115旦尼34長絲纖維。實例1-b係75旦尼34長絲纖維。 [表1].實例1a和1b的製程條件和捲曲收縮率 實例編號 PTT/PET顆粒的IV,dL/g West/模組/East溫度,°C 進料輥速度,m/min和溫度,°C 退火輥速度,m/min和溫度 室溫下的鬆弛輥速度,m/min 捲繞機速度,m/min CCa,% 1-a 1.25/0.64 270/270/270 1106 3540,160°C 3550/3500 3500 21.2 1-b 1.02/0.64 260/270/275 937 3000,140°C 3000/2950 2950 8.8 實例 2 PTT/PET 重量比的變化 Example 1 shows the use of PTT particles with different IVs to produce bicomponent fibers with the desired value of the crimp shrinkage (CCa) after heating. The IV of the PTT particles used to prepare the fiber is 1.25 dl/g (1a) or 1.02 dl/g (1b). In both cases, the IV of the PET pellets was 0.64 dl/g. For each example, the weight ratio of PTT to PET is 50/50. Example 1-a is 115 denier 34 filament fiber. Example 1-b is 75 denier 34 filament fiber. [Table 1].

The bicomponent fiber is 75 denier and 34 filaments. In Table 2, Comparative Examples A, B, and C show high CCa levels, that is, higher than 30%, and are more suitable for clothing products that require stretching and recovery. Examples 2a, 2b, and 2c show the process conditions that result in the production of a bicomponent fiber with a high degree of expansion of 30% or less crimp shrinkage after heating, which is suitable for making carpets. For Comparative Example A, the winder speed was 3495 m/min; and for Comparative Examples B and C and Examples 2a, 2b, and 2c, the winder speed was 3500 m/min. [Table 2].

表3示出了如何用PTT和co-PET的50/50共混物製備雙組分的一種組分,以及如何由PET製備第二組分。在實例3a至3e中,將0.96 IV dl/g PTT顆粒和0.82 IV dl/g co-PET顆粒的50/50重量百分比「鹽和胡椒」共混物混合在一起,直到顆粒被隨機分散。乾燥後,將顆粒混合物進料到West擠出機中。將乾燥的0.50 IV PET均聚物顆粒進料到East擠出機中。然後用包含如上所述之PTT/co-PET的50/50重量共混物的第一組分和係PET的第二組分製備雙組分纖維,其中兩種組分之間的重量比有所變化。例如,實例3a以第一組分(即50/50的PTT/co-PET共混物)和第二組分(即PET)之間70/30重量比製備。在表3中的剩餘實例中,聚合物保持不變且只改變兩種組分之間的重量比。對於所有該等實例,捲繞機速度為3500 m/min。 [表3].實例3 製程條件和獲得的捲曲收縮率 實例編號 PTT/co-PET共混物與PET的重量比 West/模組/East溫度,°C 進料輥速度,m/min 退火輥速度,m/min 鬆弛輥速度,m/min Cca,% 3-a 70/30 265/265/270 1196 3560 3535/3530 28 3-b 60/40 265/265/270 1196 3560 3535/3530 27.9 3-c 50/50 265/265/270 1196 3560 3535/3530 26.9 3-d 40/60 265/265/270 1196 3560 3535/3530 24.5 3-e 30/70 265/265/270 1196 3560 3530/3535 3.3 實例 4 具有兩種組分之間的固定重量比的一種組分中 PTT/co-PET 共混比 的變化 Table 3 shows how to use a 50/50 blend of PTT and co-PET to prepare one component of the two-component, and how to prepare the second component from PET. In Examples 3a to 3e, a 50/50 weight percent "salt and pepper" blend of 0.96 IV dl/g PTT particles and 0.82 IV dl/g co-PET particles was mixed together until the particles were randomly dispersed. After drying, the pellet mixture was fed into the West extruder. The dried 0.50 IV PET homopolymer pellets were fed into the East extruder. Then a bicomponent fiber is prepared with the first component of the 50/50 weight blend of PTT/co-PET as described above and the second component of PET, wherein the weight ratio between the two components is Changed. For example, Example 3a was prepared with a 70/30 weight ratio between the first component (ie a 50/50 PTT/co-PET blend) and the second component (ie PET). In the remaining examples in Table 3, the polymer remained unchanged and only the weight ratio between the two components was changed. For all these examples, the winder speed is 3500 m/min.

表4示出了如何用PTT和co-PET共混物製備雙組分的一種組分,以及如何由PET製備第二組分。與表3相比,表4中所示的實例顯示了在保持兩種組分之間恒定的50/50重量比的同時改變第一組分內的PTT與co-PET共混比的效果。在表4中,藉由改變0.96 IV dl/g PTT和0.82 IV dl/g co-PET的「鹽和胡椒共混物」(「S&P」)中的顆粒比來製備實例4a至4d和實例4f至4g以及對比實例D。將顆粒混合在一起,直到被隨機分散。乾燥後,將顆粒混合物進料到West擠出機中。將乾燥的0.50 IV PET均聚物顆粒進料到East擠出機中。然後用包含如上所述之PTT/co-PET共混物的第一組分和包含PET的第二成員製備雙組分纖維,其中兩種成員之間的重量比固定在50/50。例如,在實例4a中,雙組分的第一組分由10/90共混比的PTT/co-PET製成,並且雙組分的第二組分由PET製成。兩種組分之間的重量比為50/50。在實例4-e中,PTT和co-PET顆粒在雙螺桿擠出機中預混配、淬滅、造粒並在使用前重新乾燥。這與實例4d形成對比,在實例4d中組分由鹽和胡椒共混物製成。還應注意的是,對比實例D含有較高的加熱後捲曲收縮率值,%CCa = 43.1,更適合於服裝織物的高拉伸水平。Table 4 shows how to prepare one component of the two-component blend of PTT and co-PET, and how to prepare the second component from PET. Compared with Table 3, the example shown in Table 4 shows the effect of changing the blend ratio of PTT to co-PET in the first component while maintaining a constant 50/50 weight ratio between the two components. In Table 4, Examples 4a to 4d and Example 4f were prepared by changing the particle ratio in the "Salt and Pepper Blend" ("S&P") of 0.96 IV dl/g PTT and 0.82 IV dl/g co-PET To 4g and Comparative Example D. Mix the particles together until they are randomly dispersed. After drying, the pellet mixture was fed into the West extruder. The dried 0.50 IV PET homopolymer pellets were fed into the East extruder. Then a bicomponent fiber is prepared with the first component comprising the PTT/co-PET blend as described above and the second component comprising PET, wherein the weight ratio between the two members is fixed at 50/50. For example, in Example 4a, the first component of the two-component is made of PTT/co-PET with a blend ratio of 10/90, and the second component of the two-component is made of PET. The weight ratio between the two components is 50/50. In Example 4-e, PTT and co-PET pellets were pre-mixed in a twin screw extruder, quenched, pelletized and re-dried before use. This is in contrast to Example 4d, where the components are made from a blend of salt and pepper. It should also be noted that Comparative Example D contains a higher value of crimp shrinkage after heating, %CCa = 43.1, which is more suitable for high stretch levels of clothing fabrics.

可以使用上面實例2a中所述之聚合物、聚合物IV和纖維重量比,以1200旦尼-120長絲(10 dpf)紡絲出包含自膨化性雙組分纖維的地毯。與實例2a相比,該等雙組分纖維將具有更高的旦尼和長絲數量。將調整紡絲速度(即拉伸比),使得所得纖維具有30%或更低的加熱後捲曲收縮率。如此製成的雙組分纖維可以在標準加撚設備上與同一類型的第二雙組分纖維進行合股。加撚後,可以藉由Superba®熱定型設備對纖維進行加工,該設備將使雙組分纖維捲曲充分展現並使合股的紗線中的撚度定型。然後,可以將熱定型的雙組分紗線在標準地毯簇絨機上與其他相同組成的熱定型紗線一起簇絨化成非機織的聚丙烯背襯,以得到完全由熱定型的、合股的雙組分紗線組成的簇絨織物。然後,可以在地毯工業使用的標準加工設備上對簇絨織物進行加工,以在地毯的背面施加乳膠配製物,該乳膠配製物將簇絨面纖維鎖定在機織的地毯背襯中。然後將施加二次背襯以保護地毯的底面。坯布(未乾燥的)地毯可以在標準的連續染色設備上進行加工,並且然後在連續烘箱中乾燥以除去水分。然後將成品地毯卷到大管上用於現場安裝。實例 6 使用如實例 2a 中的自膨化性雙組分纖維生產地毯 The polymer, polymer IV, and fiber weight ratio described in Example 2a above can be used to spin 1200 denier-120 filaments (10 dpf) to produce carpets containing self-expandable bicomponent fibers. Compared to Example 2a, these bicomponent fibers will have higher denier and filament counts. The spinning speed (ie, draw ratio) will be adjusted so that the resulting fiber has a crimp shrinkage after heating of 30% or less. The bicomponent fiber thus produced can be plied with a second bicomponent fiber of the same type on standard twisting equipment. After twisting, the fiber can be processed by the Superba® heat setting equipment, which will fully display the bicomponent fiber crimp and set the twist in the twisted yarn. Then, the heat-set bi-component yarn can be tufted together with other heat-set yarns of the same composition on a standard carpet tufting machine into a non-woven polypropylene backing to obtain a fully heat-set, plied Tufted fabric composed of bi-component yarns. The tufted fabric can then be processed on standard processing equipment used in the carpet industry to apply a latex formulation to the back of the carpet that locks the tufted face fibers in the woven carpet backing. A secondary backing will then be applied to protect the underside of the carpet. Grey fabric (undried) carpet can be processed on standard continuous dyeing equipment and then dried in a continuous oven to remove moisture. Then roll the finished carpet onto a big tube for on-site installation. Example 6: Production of carpet using self-expandable bicomponent fiber as in Example 2a

可以使用上面實例2a中所述之聚合物、聚合物IV和纖維重量比,以1200旦尼-120長絲(10 dpf)紡絲出包含自膨化性雙組分纖維的地毯。選擇噴絲孔來製作並列的三葉形橫截面,儘管可以選擇對地毯製造有用的任何其他橫截面形狀。該等雙組分纖維將具有與實例2a相比更高的旦尼和長絲數量以及三葉形橫截面形狀。將調整紡絲速度(即拉伸比),使得所得纖維具有30%或更低的加熱後捲曲收縮率。如此製成的雙組分纖維可以在標準加撚設備上與同一類型的第二雙組分纖維進行合股。加撚後,可以藉由Superba®熱定型設備對纖維進行加工,該設備將使雙組分纖維捲曲充分展現並使合股的紗線中的撚度定型。然後,可以將熱定型的雙組分紗線在標準地毯簇絨機上與其他相同組成的熱定型紗線一起簇絨化成非機織的聚丙烯背襯,以得到完全由熱定型的、合股的雙組分紗線組成的簇絨織物。然後,可以在地毯工業使用的標準加工設備上對簇絨織物進行加工,以在地毯的背面施加乳膠配製物,該乳膠配製物將簇絨面纖維鎖定在機織的地毯背襯中。然後將施加二次背襯以保護地毯的底面。坯布(未乾燥的)地毯可以在標準的連續染色設備上進行加工,並且然後在連續烘箱中乾燥以除去水分。然後將成品地毯卷到大管上用於現場安裝。The polymer, polymer IV, and fiber weight ratio described in Example 2a above can be used to spin 1200 denier-120 filaments (10 dpf) to produce carpets containing self-expandable bicomponent fibers. The spinneret holes are selected to make side-by-side trilobal cross-sections, although any other cross-sectional shape useful for carpet manufacturing can be selected. These bicomponent fibers will have a higher denier and filament count and trilobal cross-sectional shape compared to Example 2a. The spinning speed (ie, draw ratio) will be adjusted so that the resulting fiber has a crimp shrinkage after heating of 30% or less. The bicomponent fiber thus produced can be plied with a second bicomponent fiber of the same type on standard twisting equipment. After twisting, the fiber can be processed by the Superba® heat setting equipment, which will fully reveal the crimp of the bicomponent fiber and set the twist in the twisted yarn. Then, the heat-set bi-component yarn can be tufted together with other heat-set yarns of the same composition on a standard carpet tufting machine into a non-woven polypropylene backing to obtain a fully heat-set, plied Tufted fabric composed of bi-component yarns. The tufted fabric can then be processed on standard processing equipment used in the carpet industry to apply a latex formulation to the back of the carpet that locks the tufted face fibers in the woven carpet backing. A secondary backing will then be applied to protect the underside of the carpet. Grey fabric (undried) carpet can be processed on standard continuous dyeing equipment and then dried in a continuous oven to remove moisture. Then roll the finished carpet onto a big tube for on-site installation.
