Description
본 발명은 3종의 소재를 이용하여 경량감과 신축성, 흡한속건성, 보온·방열성등의 기능성이 우수한 다층구조사를 이용한 다기능성 양방향 신축직물의 제조방법에 관한 것이다. The present invention relates to a method for producing a multifunctional bi-directional stretch fabric using a multi-layered yarn having excellent functionality such as light weight, elasticity, sweat-absorbing quick-drying, thermal insulation and heat dissipation using three kinds of materials.
종래의 신축직물을 제조하기 위한 다층구조 복합사는 사가공기술(복합 인터레이싱, 에어텍스쳐 기술)과 방적기술 등에 의해 제조되었으며, 상기 사가공기술에 의한 방법은 군혼합 또는 균일혼합 방법의 일종으로서 균일한 층구조 형성이 불가능하였다. 방적기술에 의한 방법은 균일혼합, 군혼합, 층혼합의 모든 구조가 가능하며 주로 링 방적공정 중 연조공정에서 2층 슬라이버를 제조, 조방공정에서 2층 조사를 제조, 정방공정에서 2·3층구조 방적사를 제조하는 기술이 있으며 특히 국외(일본)의 경우 자사의 방적기술에 의해 PET/면, PET/PET 등의 단섬유로 복합 다층구조사를 제조하여 편물로서 스포츠웨어 용도로 많이 전개되고 있었으나 이러한 방법으로는 필라멘트/필라멘트의 복합사 제조가 불가능하며 신축성이 높은 제품을 얻기 위해서는 편물에만 적용이 가능한 문제점이 있었다.Conventional multi-layer composite yarns for the production of stretch fabrics have been manufactured by means of microfabrication technology (composite interlacing, air texture technology) and spinning technology, and the method by the microfabrication technology is a kind of group mixing or uniform mixing method. One layer structure was impossible. The method by spinning technique is possible for all structures of homogeneous mixing, group mixing, and layer mixing, mainly manufacturing two-layer sliver in the softening process of ring spinning process, manufacturing two-layer irradiation in the spinning process, and producing 2 · 3 in the spinning process. There is a technology for manufacturing layered yarns, and especially in Japan (Japan), its multi-layered yarns were manufactured with short fibers such as PET / cotton and PET / PET by its spinning technology, and they have been widely developed for sportswear as knitted fabrics. In this way, it is impossible to manufacture a composite yarn of filament / filament and there is a problem that can be applied only to knitting to obtain a highly elastic product.
또한 국내 스포츠웨어용 의류로 적용되는 기능성 신축성 제품으로는 대부분이 편물(KNIT)이며 다층구조사를 사용한 기능성 제품 개발은 전개되지 못하고 있었다. 편물은 편환(루프)에 의해 구조적으로 신축성이 발현되나 반복적인 세탁과 착용에 의해 형태안정성이 부족하고 올 풀림 등의 취급이 용이하지 못한 문제점이 있었다. In addition, most of the functional elastic products that are applied to apparel for sportswear in Korea are knitted (KNIT), and the development of functional products using multi-layered yarn has not been developed. The knitted fabric is structurally stretched by a circular loop (loop), but there is a problem in that it is insufficient in form stability due to repeated washing and wearing, and handling is not easy.
신축성을 나타내는 것으로는 스판덱스 신축직물을 들 수 있으나 이는 경·위사가 교차된 구조로서 편물에 비해 신축성은 다소 부족하나 형태안정성이 우수한 장점을 가지고 있다. 그러나 경사와 위사 양방향(투웨이)제품은 생산 및 품질상 문제로 인해 후(厚)직물 분야에 적용되고 있을 뿐만 아니라 신축성이 15-20% 수준으로 경량 및 고신축성을 요하는 제품에 대한 전개는 미비한 실정이다. The stretchy stretch may include spandex stretch fabric, but it is a structure in which the warp and weft are intersected. However, warp and weft bi-directional (two-way) products are not only applied to post-woven fabrics due to production and quality problems, but also the development of products requiring lightweight and high elasticity with 15-20% elasticity is insufficient. to be.
따라서 본 발명의 목적은 상기 선행기술의 문제점을 해결하기 위하여 편물제품이 아닌 직물로서 기존의 방적방법과 차별화된 필라멘트/면, 필라멘트/필라멘트 복합화하여 보온·방열, 흡한속건, 환기효과의 쾌적함 및 우수한 신축성효과를 가지는 다기능성 양방향 신축직물의 제조방법을 제공하는데 있다. Accordingly, an object of the present invention is to fabricate a filament / cotton, filament / filament compound, which is differentiated from conventional spinning methods, as a fabric, not a knitted product to solve the problems of the prior art. The present invention provides a method for producing a multifunctional bidirectional stretch fabric having an elastic effect.
상기한 과제를 해결하기 위하여 본 발명자는 스판덱스, PET DTY사 및 이형단면 폴리에스테르 필라멘트를 복합커버링한 150∼200d 다층구조사를 사용하고 경,위사밀도를 조절하여 제직하면 신축성이 우수하면서도 흡수성과 건조성, 보온성이 우수한 경량의 양방향 신축직물을 제조할 수 있다는 것을 알게 되어 본 발명을 완성하게 된 것이다. In order to solve the above problems, the present inventors use a 150-200d multi-layered yarn which is a composite cover of spandex, PET DTY yarns and release cross-section polyester filament, and when weaving by adjusting the hardness and weft density, it is excellent in elasticity and absorbency The present invention has been completed by knowing that it is possible to manufacture a lightweight bidirectional stretch fabric having excellent thermal insulation.
그러므로 본 발명에 의하면 양방향 신축직물의 제조방법에 있어서, 내층용으로 30∼40 데니아인 스판덱스 필라멘트, 중층용으로 단사섬도 0.1∼0.3 데니아인 폴리에스테르 DTY사, 외층용으로 단사섬도 1∼3 데니아인 이형단면 폴리에스테르 필라멘트를 공급하여 연신비 2∼3 배 및 꼬임수 600∼800(T/M)으로 이중커버링하여 기능성이 발휘되는 150∼200d 다층구조 복합사를 제조하고, 상기 다층구조 복합사를 경,위사로 사용하여 제직하는 것을 포함하는 것을 특징으로 하는 다층구조사를 이용한 다기능성 양방향 신축직물의 제조방법이 제공된다.Therefore, according to the present invention, in the manufacturing method of bidirectional stretch fabric, spandex filament having 30-40 denier for inner layer, polyester DTY having 0.1-0.3 denier for single layer for middle layer, and 1-3 denier for single layer for outer layer Supply 150-200d multi-layered composite yarn with functionality by supplying a double-sided polyester filament with a draw ratio of 2-3 times and twisting number of 600-800 (T / M). , Provided is a method for producing a multi-functional bi-directional stretch fabric using a multi-layer structure yarn, characterized in that weaving using as a weft.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명에서는 양방향 신축직물의 기능성을 발휘하기 위해 기능성 다층구조사를 제조하고 이를 각각 경·위사로 하여 특정한 경,위사 밀도로 제직함으로써 다층구조사 외층의 빠른 흡수성 및 발산성, 중층의 미세 정지공기층에 의한 보온성 및 체온유지, 내층의 스판덱스에 의해 우수한 신축성능을 골고루 발현할 수 있는 다기능성 양방향 신축직물을 제조한다.In the present invention, the functional multi-layered yarns are manufactured in order to exhibit the functionality of the bidirectional stretch fabric, and weaving them into specific hard and weft densities, respectively, by using light and weft yarns. By maintaining the heat retention and body temperature, the inner layer spandex to produce a multi-functional bi-directional stretch fabric capable of evenly expressing excellent stretch performance.
우선, 다기능성 양방향 신축직물을 구성하는 경,위사로 사용될 다층구조사는 내층용으로 30∼40 데니아인 스판덱스 필라멘트, 중층용으로 단사섬도 0.1∼0.3 데니아인 폴리에스테르 DTY사, 외층용으로 단사섬도 1∼3 데니아인 이형단면 폴리에스테르 필라멘트를 공급하여 연신비 2∼3 배 및 꼬임수 600∼800(T/M)으로 이중커버링하여 다층구조 복합사를 제조하게 되는데, 상기 내층용 스판덱스 필라멘트를 공급롤러(Feed roller)에 투입하여 제 1 스핀들에 감겨있는 상기 중층용소재를 Z방향으로 꼬임수 600∼800(T/M)으로 커버링하고 제 2 스핀들에 감겨있는 상기 외층소재를 S방향으로 꼬임수 600∼800(T/M)으로 커버링할 수 있다. 상기 중층용소재는 S방향으로, 외층용소재는 Z방향으로 커버링할 수 있는데 중층용소재와 외층용소재의 각각 반대방향의 꼬임이 합연되면 토크가 발생하지 않는 견고한 커버링효과가 발휘되는 장점과 내·중·외층 소재에 의해 기능성이 발휘되는 장점이 있다. 이후 공급롤러와 드래프트 롤러의 속도차이에 의해 스판덱스 연신비 2∼3 배로 설정하여 권취롤러에 권취한다. First, the multi-layer structure yarn to be used as the light and weft yarn constituting the multi-functional bi-directional stretch fabric, spandex filament 30-30 denier for the inner layer, polyester DTY yarn 0.1-0.3 denier for the middle layer, single yarn fineness for the outer layer 1 Supplying a multi-layered polyester filament of ˜3 denier and double covering with a draw ratio of 2 to 3 times and twisting number of 600 to 800 (T / M) to produce a multi-layered composite yarn, and supplying the inner layer spandex filament to a supply roller ( Covering the middle layer material wound on the first spindle and twisted in the Z direction by 600 ~ 800 (T / M) and feeding the outer layer material wound on the second spindle in the S direction by 600 ~ It can cover up to 800 (T / M). The middle layer material may be covered in the S direction, the outer layer material may be covered in the Z direction, and when the twists in the opposite directions of the middle layer material and the outer layer material are combined, the strong covering effect without generating torque is exerted. The advantage is that the functionality is exhibited by the middle and outer layer materials. Thereafter, the feed roller and the draft roller are set to have a spandex draw ratio of 2 to 3 times depending on the speed difference between the feed roller and the draft roller, and wound around the winding roller.
상기 다층구조사의 구성요소 중 외층소재인 이형단면 폴리에스테르 필라멘트는 모세관현상에 의해 액체상의 땀을 신속히 흡수/발산시키는 기능을 할 수 있고, 중층소재인 폴리에스테르 멀티필라멘트는 DTY사를 사용하여 운동중에 발생되는 액체상의 땀에 의한 인체의 체온저하를 방지하기 위해 미세정지공기층을 유발할 수 있어 운동후에도 체온조절을 할 수 있게 되어 친수성 관능기를 가지는 일반 면직물보다 흡수성과 건조성이 우수하며 일반 PET 직물보다 우수한 흡수성이 우수한 기능을 가지게 된다. Outer cross-sectional polyester filament of the outer layer material of the multi-layered structure of the yarn can function to quickly absorb / dissipate the sweat of the liquid phase by capillary action, the polyester multi-filament of the middle layer material during the exercise using DTY In order to prevent the body temperature drop caused by sweating of the liquid phase, it is possible to induce a fine stop air layer, so that the body temperature can be controlled after exercise, which is superior to general cotton fabrics having a hydrophilic functional group and superior to general PET fabrics. It has a function of excellent absorbency.
본 발명에서는 이렇게 준비된 다층구조사를 사용하여 직물을 제조하게 되는데, 직물의 경사밀도와 위사밀도는 경·위사 신축률에 영향을 미치는 중요한 직물구조 인자로서 본 발명에서는 경사밀도 90∼110본/인치 및 위사밀도 60∼80본/인치로 제직하는 것이 바람직하다. 밀도를 상기 범위보다 적게 하면 직물이 엉성하고 반발 탄력성이 없으며, 밀도를 높게 하면 신축성 저하와 순간적인 흡수성의 저하를 유발하고 외관이 나빠지게 된다. In the present invention, the fabric is prepared using the multi-layered yarn prepared as described above, and the warp density and weft density of the fabric are important fabric structural factors influencing the warp and weft stretch rate. It is preferable to weave at a weft density of 60 to 80 articles / inch. If the density is less than the above range, the fabric is coarse and there is no rebound elasticity, and if the density is high, the elasticity decreases and the instantaneous absorbency decreases, and the appearance becomes bad.
제직이 완료된 후에는 제직된 직물의 신축성을 최대한 발휘하기 위해 정련축소공정을 거치고, 염색 및 최종 열고정하여 본 발명의 다층구조사 기능성 신축성 직물을 제조할 수 있다. After weaving is completed, the multi-layered yarn functional stretchable fabric of the present invention may be manufactured by undergoing a refinement reduction process, dyeing, and final heat setting in order to maximize the stretchability of the woven fabric.
이하 다음의 실시예에서는 본 발명에서는 다층구조사 기능성 신축 직물의 제조방법에 대한 비한정적인 예를 보여주고 있다. In the following examples, the present invention shows a non-limiting example of the method for producing a multi-layer yarn functional stretch fabric.

[비교예 1∼2] [Comparative Examples 1 and 2]
하기 표 2의 섬유를 사용하여 편물을 제조한 후 상기 실시예 1과 동일한 방법으로 정련, 염색 및 열고정하였으나 비교예 1은 1욕 염색으로 분산염료, 비교예 2는 80℃에서 30분동안 반응성염료로 염색하여 편물을 제조하였다.To prepare a knitted fabric using the fibers shown in Table 2 below, in the same manner as in Example 1 was refined, dyed and heat-set, but Comparative Example 1 in one bath dyeing dye dispersion, Comparative Example 2 reactive at 80 ℃ for 30 minutes Dyeing with a dye to prepare a knit.
상기 실시예 및 비교예에 의해 제조한 직물의 특성으로 흡수성은 KS K 0815 바이렉스 실험방법에 의거하여 측정하였고, 건조성은 물을 100% 흡수하여 15분 경과후의 수분함량률로 측정하였으며, 열적특성(보온성)은 KES-F7 써멀라보 (Thermal labo) Ⅱ 시스템을 이용하여 측정하였다. 그리고 신축성은 가와바다 시스템의 인장특성 중 신축률(EMT)의 데이터를 이용하여 평가하였다. As a characteristic of the fabrics prepared according to the examples and comparative examples, the water absorbency was measured according to the KS K 0815 Byrex test method, and the dryness was measured by the water content after 15 minutes after absorbing 100% of water. (Thermal insulation) was measured using KES-F7 Thermal labo II system. In addition, the elasticity was evaluated using the data of the elastic modulus (EMT) of the tensile properties of the Kawasea system.
실시예1의 직물은 비교예의 편물과 비교해 볼 때 흡수성이 우수하고, 수분함량률이 낮아 그만큼 수분이 빨리 방출되므로 건조성이 뛰어났다. 이는 중층과 외층소재의 공극차이와 외층의 모세관현상 때문으로 판단된다. 또한 수분전달이 빨라 건조성이 우수하여 수분에 의한 차가운 느낌을 방지하여 방열성이 높으며, 보온성은 30%정도로서 우수한 보온성을 부여할 수 있고 신축성도 35% 수준으로 우수한 신축성을 부여할 수 있었다.Compared with the knitted fabric of the comparative example 1, the fabric of Example 1 was excellent in absorbency and low in moisture content, so that the moisture was quickly released, and thus excellent in dryness. This may be due to the gap between the middle and outer layers and the capillary phenomenon in the outer layers. In addition, the moisture transfer is fast, and the drying property is excellent, preventing the cold feeling caused by the moisture, the heat dissipation is high, the heat retention is about 30%, it can be given excellent heat retention, and the elasticity was also able to give excellent elasticity at the level of 35%.
이상 설명한 바와 같이 본 발명에 의하면 다층구조 복합사의 효과에 의해 일반 면직물과 폴리에스테르 직물에 비해 흡수성과 건조성, 보온성이 우수하며 원료로 사용되는 다층구조 복합사의 물성에 적합한 직물설계로 경위사 양방향으로 30∼40% 정도의 신축성과 220g/m2의 직물 무게를 가지는 하절기 스포츠용 언더웨어 용도로 적합한 다기능성 경량 직물을 얻을 수 있다.As described above, according to the present invention, due to the effect of the multi-layered composite yarn, it is superior in absorbency, dryness, and thermal insulation, compared to general cotton fabrics and polyester fabrics, and is suitable for the physical properties of the multi-layered composite yarn used as raw materials. It is possible to obtain a multifunctional lightweight fabric suitable for summer sports underwear with a stretch of about 30 to 40% and a fabric weight of 220 g / m 2 .
