Abstract
本發明的吸濕性芯鞘複合絲係芯部聚合物為聚醚酯醯胺共聚合體，鞘部聚合物為聚醯胺，沸水收縮率為6~11%。 The core polymer of the hygroscopic core-sheath composite yarn system is a polyetheresteramide copolymer, the sheath polymer is a polyamide, and the boiling water shrinkage is 6 to 11%.
本發明提供的芯鞘複合纖維係可實現高吸濕性能、及具有能承受實際使用之吸濕性能的耐洗滌性、且柔軟的手感。 The core-sheath composite fiber system provided by the present invention can realize high moisture absorption performance, and has washing resistance that can withstand the actual use of the moisture absorption performance, and a soft hand.
Description
本發明係關於手感優異的吸濕性芯鞘複合絲。 The present invention relates to a hygroscopic core-sheath composite yarn excellent in feel.
由聚醯胺或聚酯等熱可塑性樹脂構成的合成纖維，由於強度、耐藥性、耐熱性等均優異，因而廣泛使用於衣料用途或產業用途等。 Synthetic fibers composed of thermoplastic resins such as polyamide or polyester are excellent in strength, chemical resistance, heat resistance, etc., and therefore are widely used in clothing applications or industrial applications.
特別係聚醯胺纖維除其獨特的柔軟度、高拉伸強度、染色時的發色性、高耐熱性等特性之外，吸濕性優異，而被廣泛使用於內衣、運動衣等用途。然而，聚醯胺纖維相較於綿等天然纖維之下，難謂吸濕性充足，且會有悶熱或沾黏的問題，在舒適性方面有劣於天然纖維的問題。 In addition to its unique softness, high tensile strength, color development during dyeing, and high heat resistance, the special polyamide fiber has excellent hygroscopicity and is widely used in underwear and sportswear. However, compared with natural fibers such as cotton, polyamide fibers are hardly said to have sufficient hygroscopicity, and there will be problems of sultry or stickiness. In terms of comfort, they are inferior to natural fibers.
從此種背景觀之，為防止悶熱或沾黏而呈現優異吸放濕性、且具有接近天然纖維舒適性的合成纖維，主要在內襯用途或運動衣料用途備受期待。 From this background, synthetic fibers that exhibit excellent hygroscopicity and moisture absorption and are close to the comfort of natural fibers to prevent sultry heat or stickiness are mainly expected for lining applications or sportswear applications.
所以，在聚醯胺纖維中添加親水性化合物的方法係一般最常被探討。例如專利文獻1提案有：藉由將親水性聚合物的聚乙烯吡咯啶酮摻合於聚醯胺中進行紡絲，俾提升吸濕性能的方法。 Therefore, the method of adding a hydrophilic compound to polyamide fibers is generally the most commonly discussed. For example, Patent Document 1 proposes a method of blending polyvinylpyrrolidone, which is a hydrophilic polymer, into polyamide to perform spinning to improve moisture absorption performance.
另一方面，將纖維構造設為芯鞘構造，以高吸濕性的熱可塑性樹脂為芯部，且以力學特性優異的熱可塑性樹脂為鞘部，而形成芯鞘構造，藉此兼顧吸濕性能與力學特性的探討正盛行。 On the other hand, the fiber structure is a core-sheath structure, a thermoplastic resin with high hygroscopicity is used as a core, and a thermoplastic resin with excellent mechanical properties is used as a sheath to form a core-sheath structure, thereby taking into account moisture absorption. Discussion on performance and mechanical characteristics is prevailing.
例如專利文獻2所記載的芯鞘複合纖維，係由芯部與鞘部構成，且呈芯部未露出於纖維表面之形狀的芯鞘複合纖維，而芯部係硬鏈段為6-尼龍的聚醚嵌段醯胺共聚合物，鞘部係6-尼龍樹脂，且纖維橫截面的芯部與鞘部之面積比率係3/1~1/5。 For example, the core-sheath composite fiber described in Patent Document 2 is composed of a core portion and a sheath portion, and the core-sheath composite fiber has a shape in which the core portion is not exposed on the fiber surface, and the core portion is a 6-nylon hard segment Polyether block amide copolymer, the sheath part is 6-nylon resin, and the area ratio of the core part to the sheath part of the fiber cross section is 3/1~1/5.
再者，專利文獻3所記載的芯鞘複合纖維，係以熱可塑性樹脂為芯部、且以纖維形成性聚醯胺樹脂為鞘部的芯鞘型複合纖維，其特徵在於：形成該芯部的熱可塑性樹脂之主成分係聚醚酯醯胺，且芯部比率佔複合纖維總重量5~50重量%；該吸濕性優異的芯鞘型複合纖維，係將聚醚酯醯胺分配於芯部、且將聚醯胺分配於鞘部，而顯現出高吸濕性。 Furthermore, the core-sheath composite fiber described in Patent Document 3 is a core-sheath composite fiber having a thermoplastic resin as a core and a fiber-forming polyamide resin as a sheath, characterized in that the core is formed The main component of the thermoplastic resin is polyetheresteramide, and the core ratio accounts for 5 to 50% by weight of the total weight of the composite fiber; the core-sheath composite fiber with excellent hygroscopicity, the polyetheresteramide is distributed in The core and the polyamide are distributed in the sheath to show high hygroscopicity.
再者，專利文獻4所記載的具有吸放濕性之複合纖維，係以聚醯胺或聚酯為鞘成分、且以由聚環氧乙烷之交聯物所構成的熱可塑性吸水性樹脂為芯成分。此處所記載的高吸濕芯鞘複合纖維，係將高吸濕性的非水溶性聚環氧乙烷改質物分配於芯部、且將聚醯胺分配於鞘部。 In addition, the composite fiber having hygroscopicity and moisture absorption described in Patent Document 4 is a thermoplastic water-absorbent resin that uses polyamide or polyester as a sheath component and is composed of a cross-linked product of polyethylene oxide For the core composition. The highly hygroscopic core-sheath composite fiber described here dispenses a highly hygroscopic water-insoluble polyethylene oxide modified product to the core, and dispenses polyamide to the sheath.

然而，專利文獻1所記載的纖維，雖具有接近天然纖維的吸放濕性，但其性能尚無法充分滿足，達成更高吸放濕性便成為課題。 However, although the fiber described in Patent Document 1 has hygroscopicity close to that of natural fibers, its performance is not yet sufficiently satisfied, and achieving higher hygroscopicity becomes a problem.
再者，專利文獻2~4的芯鞘複合纖維，雖具有與天然纖維同等級或以上的吸放濕性，但芯部會因重複實際使用而劣化，會有因重複使用導致吸濕性能降低的問題。又，形成布帛時的手感亦是與尼龍同等級的柔軟度，因而尚不充分。強烈期待超越現有物的柔軟手感。 Furthermore, although the core-sheath composite fibers of Patent Documents 2 to 4 have the same level of moisture absorption and desorption as natural fibers, the core part will be deteriorated by repeated actual use, and the moisture absorption performance will be reduced due to repeated use The problem. In addition, the texture when forming the fabric is also the same level of softness as nylon, which is not sufficient. Strongly look forward to the soft feel beyond the existing.
本發明之目的係克服上述習知技術的問題，並提供：能實現具有高吸濕性能、超越天然纖維的舒適性、能承受實際使用之吸濕性能的耐洗滌性、以及截至目前所沒有的柔軟手感的芯鞘複合絲。 The purpose of the present invention is to overcome the problems of the above-mentioned conventional technology and provide: it can achieve high hygroscopic performance, comfort beyond natural fibers, washing resistance that can withstand the hygroscopic performance of actual use, and what is not available so far Core-sheath composite silk with soft touch.

為能將沸水收縮率設為6~11%，除形成上述芯鞘複合絲之外，較佳係在絲生產時分為2階段施行油劑賦予。油劑係用於提升絲之平滑性或收束性所必要的，但對已完成冷卻固化的紗線賦予水溶液(乳化液)，並放置一定時間後，再度賦予乳化液，便可輕易地使沸水收縮率降低。認為其理由係在第1階段賦予之同時對絲 供應水分，此時會進行結晶化，更進一步利用第2階段的供油確保平滑性與收束性。若第1階段與第2階段賦予時間的間隙係20msec以上，則可輕易將沸水收縮率控制於本發明的規定內，故較佳。賦予時間的間隙越長越好，但由於拉長時間間隙便必需延長步驟，因而最好考慮效率性生產之後再行設定。另外，絲的紡絲速度3000m/分、第1階段與第2階段的油劑賦予位置差為1.5m時，賦予時間的間隙係30msec。又，將油劑賦予時的絲張力設定在0.15~0.40cN/dtex範圍內，便會促進絲配向，因而將沸水收縮率設定在本規定內較佳。另外，絲張力係在第1階段至第2階段之間測定。又，本發明芯鞘複合絲的伸度較佳係60~90%。為能提升柔軟性，最好施行假撚加工，而為施行假撚加工，若伸度係60~90%，則皺縮的經時變化或重複拉伸時的皺縮降低較少，且能更加提升絲的柔軟性，故較佳。 In order to be able to set the boiling water shrinkage to 6 to 11%, in addition to forming the above-mentioned core-sheath composite yarn, it is preferable to apply the oil agent in two stages during the production of the yarn. The oil agent is necessary for improving the smoothness or converging property of the silk. However, the aqueous solution (emulsion) is given to the yarn that has been cooled and solidified, and after being left for a certain period of time, the emulsion is given again, so that it can be easily used Boiling water shrinkage is reduced. I think the reason is that the silk When water is supplied, it will crystallize at this time, and further use the oil supply in the second stage to ensure smoothness and convergence. If the gap between the first stage and the second stage is 20 msec or more, the boiling water shrinkage can be easily controlled within the specifications of the present invention, which is preferable. The longer the gap given time, the better. However, since the gap needs to be extended for a long time, it is better to set it after considering efficiency production. In addition, when the spinning speed of the yarn is 3000 m/min, and the difference between the first and second oil application positions is 1.5 m, the time gap is 30 msec. In addition, setting the yarn tension at the time of applying the oil agent within the range of 0.15 to 0.40 cN/dtex promotes the alignment of the yarn, so it is preferable to set the boiling water shrinkage within this specification. In addition, the yarn tension is measured between the first stage and the second stage. In addition, the elongation of the core-sheath composite yarn of the present invention is preferably 60 to 90%. In order to improve the softness, it is best to perform false twist processing, and for false twist processing, if the elongation is 60~90%, the shrinkage changes over time or the shrinkage during repeated stretching is reduced less, and can The softness of the silk is further improved, so it is better.

If the relative viscosity of o-chlorophenol is 1.2 or more, in addition to being able to apply the best adaptability to the sheath during spinning, promote the crystallization of the polyamide in the sheath, and easily control the shrinkage of boiling water, it can also improve the washing resistance of ΔMR , It is better.
