본 발명은 특유의 감성 표현이 가능한 데님원단에 관한 것으로, 보다 상세하게는 염색사인 경사와 미염사인 위사를 심사인 신축사에 고강도 효과사로 이루어지는 복합사로 제직함으로써 감성 표현과 더불어, 내구성이 있도록 고강도를 구현하면서도 신축성으로 편한 착용감이 발현되어 스포츠 의류로도 사용될 수 있는 데님원단에 관한 것이다. The present invention relates to a denim fabric capable of expressing unique emotions, and more specifically, by weaving a dyed warp yarn and an undyed weft yarn into a composite yarn made of a high-strength effect yarn to an elastic yarn that is a core yarn, high strength for durability and emotional expression. It is related to a denim fabric that can be used as sports clothing as well as a comfortable fit due to elasticity while implementing it.

데님이란 면 소재를 이용하여 경사는 인디고 염료를 사용하여 사염한 염색사를 사용하고, 위사로는 염색하지 않은 미염사를 사용하여 능직 또는 변화직으로 제직된다. 이러한 면 소재의 데님은 워싱가공이나 반복세탁에 의해 점차적으로 경사에 염착된 염료가 위사로 이염되거나 부분탈염되어 자연스러운 톤을 발현하게 되어 특유의 색상을 표현할 수 있다.Denim is a cotton material, and the warp is woven using indigo dyed yarn dyed with indigo dye, and undyed undyed yarn is used as the weft yarn to weave in a twill weave or a modified weave. In such a cotton denim, a natural tone can be expressed as the dye dyed on the warp is gradually transferred to the weft or partially desalted by washing or repeated washing to express a unique color.

이와 같은 데님원단에 관한 기술이 대한민국 등록특허 제10-1591041호, 공개특허 제 2011-0052092호 등에 개시되어 있다. 등록특허 제10-1591041호는 빈티지 가공시 원사가 손상되지 않도록 반응 염료를 이용한 데님의 염색방법을 제시하고 있고, 공개특허 제2011-0052092호는 소량 염색이 어렵고 염색 견뢰도가 낮은 데님원단의 문제를 개선할 수 있는 데님의 저온 침염방법을 제시하고 있다. 따라서, 종래 데님원단은 데님의 고유한 색상 발현에 관련된 염색공정이 주로 개발되고 있다. The technology related to such a denim fabric is disclosed in Korean Patent Registration No. 10-1591041, Korean Patent Publication No. 2011-0052092, and the like. Registered Patent No. 10-1591041 proposes a dyeing method of denim using reactive dyes so that the yarn is not damaged during vintage processing, and Patent Publication No. 2011-0052092 solves the problem of denim fabric with low dyeing fastness and difficult dyeing in small quantities. A low-temperature immersion dyeing method for denim that can be improved is presented. Therefore, in the conventional denim fabric, the dyeing process related to the unique color expression of denim has been mainly developed.

한편, 주 5일제 근무로 인하여 취미 및 여가시간의 증가함에 따라, 자전거나 모터 바이크와 활동성이 많은 스포츠를 즐기는 인구가 늘어가는데, 이들 스포츠 의류에 편의성과 다양한 기능성을 가지는 원단 소재가 사용되고 있다. On the other hand, with the increase of hobbies and leisure time due to the 5-day work week, the population who enjoys bicycles or motor bikes and active sports increases. Fabric materials having convenience and various functions are used for these sports clothes.

하지만, 데님원단의 경우 개성적인 표현이 가능하다는 장점은 있으나, 면 소재 특성상 강도가 좋지 못하고, 신축성이 부족한 단점이 있어, 스포츠 웨어와 같이 높은 내구성과 활동성이 요구되는 제품에 적용하기 어려워 사용에 한계가 있다. However, although denim fabric has the advantage of being able to express individuality, it has disadvantages such as poor strength and lack of elasticity due to the nature of the cotton material. there is

That is, since the embodiment is capable of various changes and may have various forms, it should be understood that the scope of the present invention includes equivalents capable of realizing the technical idea. In addition, since the object or effect presented in the present invention does not mean that a specific embodiment should include all of them or only such effects, it should not be understood that the scope of the present invention is limited thereby.

이하 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명에 따른 데님원단은 염색사인 경사와 미염사인 위사로 제직되며, 경사와 위사는 우수한 강도와 신축성을 가지도록 심사(A)와 초사(B)로 이루어지는 복합사로 형성된다. The denim fabric according to the present invention is woven with a dyed warp yarn and an undyed weft yarn, and the warp and weft yarns are formed of a composite yarn composed of a core yarn (A) and a sheath yarn (B) to have excellent strength and elasticity.

상기 경사로 사용되는 복합사는 신축사인 심사(A)와, 염색사를 포함하는 혼방사로 이루어져 심사(A) 주위에 형성되는 초사(B)로 형성된다. The composite yarn used for the warp is formed of a core yarn (A), which is a stretch yarn, and a sheath yarn (B) formed around the core yarn (A), which is made of a blended yarn including a dyed yarn.

심사(A)로는 신축성이 있는 폴리우레탄, SBS(styrene-butadiene-styrene), SBR(styrene butadiene rubber), PDMS(polydimethylsiloxane) 또는 실리콘 기반의 고무 물질을 포함할 수 있는데, 높은 신축성과 낮은 탄성 계수 및 높은 탄성 회복률을 가지는 폴리우레탄사가 바람직하다. The screening (A) may include elastic polyurethane, styrene-butadiene-styrene (SBS), styrene butadiene rubber (SBR), polydimethylsiloxane (PDMS) or silicone-based rubber materials, which have high elasticity and low modulus of elasticity and Polyurethane yarns having a high elastic recovery factor are preferred.

초사(B)로는 사염된 면 방적사와 고밀도폴리에틸렌(HDPE) 필라멘트사의 혼섬사가 사용된다. 혼섬되는 고밀도폴리에틸렌(HDPE) 필라멘트사는 밀도가 높아 조직이 치밀한 고밀도폴리에틸렌(HDPE) 수지 특성으로 인하 높은 강도와 내구성을 가지지만 염색이 잘되지 않는 특성을 가진다. 혼섬되는 고밀도폴리에틸렌사는 20~30g/d 강도와 10~50%의 신도를 가지는 것이 사용될 수 있다. As the primary yarn (B), a mixed yarn of yarn-dyed cotton yarn and high-density polyethylene (HDPE) filament yarn is used. Blended high-density polyethylene (HDPE) filament yarn has high strength and durability due to the high-density and dense structure of the high-density polyethylene (HDPE) resin, but it has a characteristic that it is difficult to dye. High-density polyethylene yarn to be mixed may be used having a strength of 20 to 30 g/d and an elongation of 10 to 50%.

여기서, 면사와 고밀도폴리에틸렌사의 혼섬비율은 60:40~80:20 (면사: 고밀도폴리에틸렌사) 중량비로 혼섬될 수 있는데, 면사가 60 중량비 미만으로 혼섬되면 색상이 제대로 발현이 되기 어렵고, 면사가 80 중량비를 초과하면 첨가되는 고밀도폴리에틸렌사 비율이 낮게 되어 내구성이 저하되는 문제가 있다. Here, the mixed fiber ratio of cotton yarn and high-density polyethylene yarn can be mixed at a weight ratio of 60:40 to 80:20 (cotton yarn: high-density polyethylene yarn). When the weight ratio is exceeded, there is a problem in that the added high-density polyethylene yarn ratio is low and durability is lowered.

그리고, 위사는 미염색사로 사염된 면 방적사를 포함하지 않는다는 것 이외에는, 상술한 복합사 구조와 동일하다. 즉, 신축사인 심사(A)를 감싸는 초사(B)로 고밀도폴리에틸렌(HDPE) 필라멘트사로 이루어진다. 따라서, 위사는 염색사를 포함하는 경사와 위사의 색상이 대비됨에 따라 데님조가 발현될 수 있다.And, the weft yarn is the same as the composite yarn structure described above, except that it does not include the cotton yarn yarn dyed with the undyed yarn. That is, it is made of high-density polyethylene (HDPE) filament yarn as the super yarn (B) that wraps the core yarn (A), which is an elastic yarn. Accordingly, as the colors of the warp and weft yarns including the dyed yarn are contrasted with the weft yarn, the denim tone can be expressed.

이와 같은 경사와 위사를 형성하는 복합사의 제조공정이 도 2에 도시되어 있다. 먼저, 심사용 피드롤러(1)로 심사(A)인 폴리우레탄사로 공기교락 노즐(4)로 공급함과 동시에, 초사용 피드롤러(2)로 초사(B)인 사염된 면사와 고밀도폴리에틸렌사의 혼섬사를 공급하여, 이들을 공기교락시킨 다음 가열롤러(5) 및 건조열판(6)으로 열처리한 후 권취롤러(8)로 권취하여 복합사로 제조할 수 있다. 이때, 심사(A)의 오버피율은 15~25%로 조절하고, 초사(B)의 오버피드율은 25~35%로 조절하고, 공기교락 가공시 공기압은 15~20kgf/㎠로 조절하고, 건조열판(6)의 온도는 170~190℃로 조절하고, 사속은 300m/분으로 조절하는 것이 가공효과를 증진하는데 바람직하다.The manufacturing process of the composite yarn for forming such warp and weft yarns is shown in FIG. 2 . First, as the feed roller for screening (1), the polyurethane yarn, which is the core (A), is supplied to the air entangling nozzle (4), and at the same time, the mixed yarn of the yarn dyed cotton and high-density polyethylene, which is the primary yarn (B), as the primary feed roller (2). After supplying, bridging them with air, and then heat-treating them with a heating roller 5 and a dry hot plate 6, and then winding them with a winding roller 8 to manufacture a composite yarn. At this time, the overfeed rate of the core yarn (A) is adjusted to 15~25%, the overfeed rate of the first yarn (B) is adjusted to 25~35%, and the air pressure is adjusted to 15~20kgf/cm2 during air entangling processing, It is preferable to adjust the temperature of the drying hot plate 6 to 170 ~ 190 ℃, and to adjust the yarn speed to 300 m / min to enhance the processing effect.

이와 같이 형성되는 복합사를 각각 위사와 경사로 능직으로 제직한 데님원단이 도 3에 도시되어 있는데, 본 발명은 도 3과 같이 개성있는 데님조 색상이 발현되면서도, 우수한 강도와 신축성이 발현되어 자전거나 모터 바이크와 같이 활동량이 많고 개성표현이 필요한 스포츠 웨어로 적용될 수 있다. A denim fabric in which the composite yarn formed in this way is woven with a weft and a warp twill, respectively, is shown in FIG. 3 , and the present invention exhibits a unique denim-like color as shown in FIG. It can be applied to sportswear that has a lot of activity and requires individual expression like a motor bike.
