Description
본 발명은 폴리에스테르계 잠재권축필라멘트―폴리에스테르 중공필라멘트를 에어텍스쳐노즐을 통해 사선방향으로 고압의 공기를 분사하여 원사 표면에 루우프를 발생시키는 에어텍스쳐 가공사를 제조하는 방법에 관한 것으로서 본 발명에 의해 보온성 및 신축성이 우수한 에어텍스쳐 가공사를 제공할 수 있다. The present invention relates to a method for producing an air-textured processed yarn for producing loops on a yarn surface by spraying high-pressure air in a diagonal direction through a polyester-based latent crimping filament-polyester hollow filament through an air-texture nozzle. It is possible to provide an air texture processing yarn excellent in warmth and stretchability.
최근 스포츠/캐주얼 웨어는 다양한 기능성 제품들이 쏟아지고 있는 가운데, 지구온난화 대책에 의한 외부환경 대응형 경량보온소재들이 다수 개발되어 오고 있다. 또한, 이러한 기능성에 더하여 쾌적성에 대한 새로운 요구에 부응하여 심리적, 감각적인 쾌적성, 편리성, 건강안전 면에서의 의류의 쾌적성이 부각되고 있다.Recently, sports / casual wear has been developed with a variety of functional products, and a number of lightweight thermal insulation materials have been developed in response to the global warming countermeasures. In addition to these functionalities, the comfort of clothes in the psychological and sensory comfort, convenience, and health and safety has been emphasized in response to new demands for comfort.
이러한 쾌적성의 주요요인으로는 의복과 피부사이의 미소공간의 온도, 습도, 기류의 적절한 조절이 필요할 분만 아니라, 의복으로부터 피부가 받는 압박력인 의복압(착용감) 및 의복과 피부와의 접촉촉감이 중요하다.The major factors of this comfort are not only the temperature, humidity, and airflow of the micro-space between clothing and skin, but also the clothing pressure (comfort) Do.
이와 같이 의복의 쾌적성을 충족시키기 위하여 의복으로부터 피부가 받는 압박력인 의복압(착용감) 및 의복과 피부와의 접촉촉감을 향상시키기 위하여 신축(Stretch)성 소재의 개발이 활발하게 이루어지고 있다. In order to satisfy the comfort of the clothes, development of a stretch material has been actively carried out in order to improve the feeling of contact between clothing and skin, which is the pressing force of the clothes, which is the pressing force that the skin receives from the clothes.
일반적으로 신축성을 부여하기 위해서는 주로 합성섬유를 사용하고 있었으며, 최근에는 친환경 제품 트렌드에 맞추어 천연소재를 적용한 제품이 선호되고 있으며 이에 면, 양모, 레이온 등의 다양한 소재들의 특수가공에 의한 신축성 발현을 도모하고 있으나, 합성섬유와 대비하여 신축성의 발현이 미비하여 신축소재로의 사용은 상용화 되고 있지 않는 실정이다. In general, synthetic fibers have been mainly used to impart elasticity. In recent years, natural products have been preferred in accordance with environment-friendly product trends. Thus, the elasticity of various materials such as cotton, rayon, However, in comparison with synthetic fibers, the elasticity is not sufficiently manifested and the use thereof as a stretchable material has not been commercialized.
의류제품에 신축성을 부여하기 위해 가장 널리 사용되고 있는 합섬소재인 스판덱스(Spandex)는 높은 신축성과 특유의 탄력성으로 가장 널리 사용되고 있다. 대표적인 방법으로는 커버링기계에서 코어는 스판덱스를 사용하고 효과사는 합섬이나 면 등의 스테이플 파이버를 나선구조의 형태로 커버링하여 제조하는 방법을 사용하고 있으나, 스핀들 속도에 의한 장력 변동과 번수에 적합한 꼬임 수 등이 일정하지 않아 제직시 문제점이 발생하고 있다. 또한, 제조공정에서의 환경오염, 고온고압 공정에서의 물성 저하, 염색 불량의 문제점을 안고 있다. 이러한 스판덱스 커버링 직물의 경우에는 경량보온의 중공사 소재를 함께 적용하여도 스판덱스의 중량감에 의하여 경량보온의 효과를 제대로 발현하지 못하는 문제를 가지고 있다. Spandex, the most widely used synthetic material to give elasticity to apparel products, is most widely used because of its high elasticity and unique elasticity. As a typical method, a core is made of spandex and a staple fiber such as a synthetic fiber is covered with a spiral structure in a covering machine, but a twist number suitable for tension fluctuation and number of turns due to the spindle speed There is a problem in the weaving. Further, there is a problem of environmental pollution in the manufacturing process, deterioration of physical properties in a high-temperature and high-pressure process, and defective dyeing. In the case of such a spandex covering fabric, even if a hollow fiber of light insulation is applied together, the effect of light insulation can not be exhibited due to the weight of the spandex.
그러므로, 상기 스판덱스커버링 직물의 단점을 해결하여 스판덱스 특유의 염색 불량, 인체 접촉 시 촉감 저하를 해결할 수 있으며, 스판덱스의 중량감을 극복하여 경량보온의 효과를 가지고, 신축, 보온의 복합기능 발현이 가능한 소재 개발이 필요한 실정이다.Therefore, it is possible to solve the disadvantages of the spandex covering fabric and to solve the problem of poor staining unique to spandex and deterioration of tactile feel upon contact with human body, to overcome the weight feeling of spandex, Development is necessary.
이러한 신축성의 향상을 위해 최근에는 잠재권축사의 개발 및 수요가 증가하고 있는 추세인데, 상기 잠재권축사는 크림프(Crimp)를 별도로 주지 않아도 내재된 잠재권축의 성질을 이용하는 신축소재로 소프트할 뿐만 아니라 양호한 신도와 벌키감이 우수하여 다양한 의류용도로 개발되고 있다. 대한민국특허출원제10-2003- 0070187호에서는 코어사로서 사이드-바이-사이드형 PTT/PET 잠재권축성 복합사를 사용하고 효과사로서 부분 배향된 PET 마이크로파이버를 사용함을 특징으로 하는 폴리에스테르계 신축성 복합 가연사를 제공하여 고도의 신축성이 발현될 뿐만 아니라, 염색성, 소프트 터치감, 작업성이 우수한 복합가연사를 제공하고 있으나, 보온효과가 발현되기 어렵고 생산비용이 높고 원사의 신축성에 의해 직물 가공 단계에서의 조건 설정에 어려운 문제가 있다.In order to improve the elasticity, the development and the demand of the pottery housing have been increasing recently. The pottery housing is soft as a new and contraction material which utilizes the inherent potential of the potential crimp even though the crimper is not separately provided It has been developed for a variety of clothes applications because of its excellent stretch and feel. Korean Patent Application No. 10-2003- 0070187 discloses a polyester-based stretchable laminate characterized by using a side-by-side PTT / PET latent sheeting composite yarn as a core yarn and a partially oriented PET micro fiber as an effect yarn The present invention provides a composite warp yarn, which not only exhibits a high degree of stretchability but also exhibits a composite warp yarn excellent in dyeing property, soft touch feeling and workability. However, since the warming effect is difficult to produce and the production cost is high, There is a difficult problem in setting the conditions in the "
보온을 위한 소재의 경우에는 최근에는 중공사 형태의 원사가 주로 개발되고 있으며, 흡한속건사의 경우는 이형단면사가 주를 이루고 있다. 이러한 소재들은 단독으로 제직에 적용되거나, 가연, 인터레이스 등의 사가공 기술, 연사공정에 의해 타소재와 복합되어 사용되는 경우도 있으나, 신축성의 발현측면에서는 충분한 성과를 거두지 못하고 있다.In the case of the material for keeping warm, a hollow fiber type yarn is mainly developed recently, and in the case of sweat-absorbing quick-drying yarn, a deformed cross-section yarn is mainly made. These materials may be applied to weaving alone, or may be used in combination with other materials by yarn processing techniques such as twisting, interlacing, and the like, but they have not achieved sufficient results in terms of stretchability.
그러므로 본 발명에서는 상기 종래기술의 단점을 극복하여 활동성, 기능성, 디자인의 측면을 모두 만족하고, 최적의 쾌적감을 발현하는 의류제품의 개발을 위해 신축성이 우수하고, 스판덱스 특유의 염색 불량 및 인체 접촉시의 촉감 저하를 해결할 수 있으며, 스판덱스의 중량감을 극복하여 경량ㆍ보온성의 기능성이 우수한 복합사를 제공하는 것을 기술적과제로 한다.Therefore, the present invention overcomes the above-mentioned disadvantages of the prior art to provide an excellent stretchability for the development of an apparel product that satisfies all the aspects of activity, functionality, and design, and exhibits an optimal comfort, And it is a technical object of the present invention to provide a composite yarn which overcomes the weight of spandex and is excellent in light weight and warmth functionality.
그러므로 본 발명에 의하면 심사로 폴리에스테르계 잠재권축필라멘트를 오버피드율 11~15%로 공급하며, Therefore, according to the present invention, the polyester based latent crimping filament is supplied at an overfeed rate of 11 to 15%
초사로 폴리에스테르 중공필라멘트를 오버피드율 18~22%로 공급하여, Polyester hollow filaments were supplied at an overfeed rate of 18 to 22%
상기 심사 및 초사를 공기압 8~15 ㎏/㎠으로 에어텍스쳐하고 170℃~200℃의 히터를 통과시켜 열처리한 후, 사속 400~450m/min로 권취하는 것을 특징으로 하는 보온성 및 신축성이 우수한 에어텍스쳐사의 제조방법이 제공된다.
Characterized in that the above-mentioned examination and napping are air-textured at an air pressure of 8 to 15 kg / cm 2, passed through a heater at 170 ° C to 200 ° C for heat treatment and then wound at a speed of 400-450 m / min. A manufacturing method of the yarn is provided.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명은 폴리에스테르계 잠재권축필라멘트―폴리에스테르 중공필라멘트를 에어텍스쳐노즐을 통해 사선방향으로 고압의 공기를 분사하여 원사 표면에 루우프를 발생시키는 에어텍스쳐 가공사를 제조하는 방법에 관한 것으로서 본 발명에 의해 보온성 및 신축성이 우수한 에어텍스쳐 가공사를 제공할 수 있다. The present invention relates to a method for producing an air-textured processed yarn for producing loops on a yarn surface by spraying high-pressure air in a diagonal direction through a polyester-based latent crimping filament-polyester hollow filament through an air-texture nozzle. It is possible to provide an air texture processing yarn excellent in warmth and stretchability.
본 발명의 에어텍스쳐사의 제조방법은 크게 심사 및 초사의 공급, 에어텍스처, 열처리 및 권취단계로 이루어진다.The manufacturing method of the air texture yarn of the present invention largely consists of the inspection and supply of superfine yarn, the air texture, the heat treatment and the winding step.
우선, 심사로 폴리에스테르계 잠재권축필라멘트를 오버피드율 11~15%로 공급하는데, 오버피드율 11%미만에서는 얻어지는 에어텍스쳐사의 강도는 증가하나, 신도가 감소되는 문제점이 있으며, 15%초과시에는 강도가 저하하고 섬도가 증가하여 실이 굵어지는 문제점이 있다.First, the polyester based latent crimping filament is supplied at an overfeeding rate of 11 to 15% by examination. When the overfeeding rate is less than 11%, the strength of the obtained air-textured yarn is increased, but the elongation is decreased. There is a problem that the strength is lowered and the fineness is increased and the thread is thickened.
한편, 초사로는 폴리에스테르 중공필라멘트를 오버피드율 18~22%로 공급하게 되는데, 오버피드율 18%미만에서는 얻어지는 에어텍스쳐사의 강도는 증가하나, 루우프 발현이 감소하는 문제점이 있으며, 22%초과시에는 강도가 저하하고 불규칙한 루우프가 많이 발현되어 에어텍스처 가공사의 품질이 저하하는 문제점이 있다.
On the other hand, the polyester hollow filament is supplied at an overfeeding rate of 18 to 22% as an initiator. When the overfeeding rate is less than 18%, the strength of the obtained air-textured yarn is increased, There is a problem in that the strength is lowered and irregular loops are much developed and the quality of the air textured yarn is deteriorated.
본 발명에서 상기 심사로 공급되는 폴리에스테르계 잠재권축필라멘트는 섬도 70d/24fila~75d/36fila, 열수축율 15~20%이고, B-force 275~282cN, 신도 25~28% 및 강도 3.5~3.8gf/d인 폴리에틸렌테레프탈레이트/폴리트리멘틸렌테레프탈레이트 사이드바이사이드형 복합사이고, In the present invention, the polyester-based latent crimping filament supplied in the present invention has a fineness of 70d / 24fila to 75d / 36fila and a heat shrinkage of 15 to 20%, a B-force of 275 to 282cN, an elongation of 25 to 28% and a strength of 3.5 to 3.8gf / d polyethylene terephthalate / polytrimethylene terephthalate side by side composite siderite,
초사로 공급되는 폴리에스테르 중공필라멘트는 70d/48fila ~ 75d/36fila, B-force 346.2~348.5cN, 신도 27~30% 및 강도 4.2~4.9gf/d인 폴리에스테르 중공필라멘트인 것이 에어텍스쳐사의 강도증진, 적절한 신도 및 루우프 발현, 중공에 의한 보온성에 특히 바람직하다.
Polyester hollow filaments that are supplied as superabsorbent are 70d / 48fila ~ 75d / 36fila, B-force 346.2 ~ 348.5cN, elongation 27 ~ 30% and strength 4.2 ~ 4.9gf / d. , Suitable elongation and loaf expression, and warmth by hollow.
이후, 상기 심사 및 초사를 에어텍스쳐 노즐에 함께 공급하여 공기압 8~15 ㎏/㎠으로 에어텍스쳐사를 형성하게 된다. 공기압 8㎏/㎠미만에서는 교락이 완전하게 이루어지지 않아 불균일한 루우프를 발생할 수 있으며, 공기압 15㎏/㎠초과시에는 고압의 공기에 의해 가공사의 물성을 저하시킬 수 있다.Then, the above-mentioned examination and napping are supplied to the air texture nozzle to form air texture yarn at an air pressure of 8 to 15 kg / cm 2. If the air pressure is less than 8 kg / cm < 2 >, the collapse is not completely performed and uneven loops can be generated. If the air pressure exceeds 15 kg / cm < 2 >
에어텍스쳐노즐의 직경은 1.2~2.0㎜로 정하는 것이 좋은데, 1.2㎜미만에서는 얻어지는 에어텍스쳐사의 강도는 증가하나, 신도가 감소되고 사치수 변화율이 증가하는 문제점이 있으며, 2.0㎜초과시에는 강도가 저하하고 불규칙 루우프가 증가하는 문제점이 있다.If the diameter of the air texture nozzle is less than 1.2 mm, the strength of the obtained air-textured yarn is increased, but the elongation is reduced and the rate of change in the number of luxuries is increased. There is a problem that irregular loops increase.
상기 심사와 초사의 공급비율은 섬도비 45:55~55:45인 것이 바람직한데, 심사비율이 45%미만인 경우에는 에어텍스쳐사의 강도가 낮아지고 신도가 너무 높아지는 문제가 발생할 수 있으며, 55%를 초과하는 경우에는 강도는 증가하나, 신도가 너무 낮아지는 문제가 발생할 수 있다.If the examination ratio is less than 45%, the strength of the air-textured yarn may be lowered and the elongation may become too high, resulting in a 55% If it exceeds, the strength is increased, but the elongation may become too low.
상기 에어텍스쳐후 복합사를 170℃~200℃의 히터를 통과시켜 열처리한 후, 사속 400~450m/min로 권취하여 본 발명의 에어텍스쳐사를 제조한다. 170℃미만에서는 열고정이 안되어서 벌키성이 유지 되지 않는 문제가 발생할 수 있으며, 200℃를 초과하는 경우에는 물성저하의 문제가 발생할 수 있다. 사속은 사속 400~450m/min로 정하여야 하는데, 400m/min미만에서는 생산성저하의 문제가 발생하며, 450m/min초과시에는 에어텍스쳐사에 대한 공기압의 침해현상에 의해 초사에 의해 얻어지는 에어텍스쳐사의 루우프가 감소하는 문제점이 발생한다.After the air-texture post-composite yarn is passed through a heater at 170 ° C to 200 ° C and heat-treated, the air-textured yarn of the present invention is produced by winding the composite yarn at a speed of 400-450 m / min. If it is less than 170 DEG C, there is a problem that the bulky property is not maintained due to the lack of thermal stability. If the temperature exceeds 200 DEG C, a problem of property deterioration may occur. In the case of less than 400 m / min, a problem of productivity deteriorates. When the air pressure exceeds 450 m / min, the air pressure of the air-textured yarn is infiltrated into the air- There is a problem in that the amount of the water is reduced.
본 발명에 의하면 섬도 150d/72fila~160d/72fila, B-force 483.5~484.2cN, 신도 22~25% 수축율 12~15% 및 강도 2.7~3.2gf/den인 것을 특징으로 하는 보온성 및 신축성이 우수한 에어텍스쳐사가 제공될 수 있는데, 보온성이 우수하고 루프발현에 의한 촉감이 우수하고 신도가 개선된 우수한 특성을 가진다. According to the present invention, it is possible to provide a heat insulating and stretchable air-permeable sheet having a fineness of 150d / 72fila to 160d / 72fila, a B-force of 483.5 to 484.2cN, an elongation of 22 to 25%, a shrinkage ratio of 12 to 15% and a strength of 2.7 to 3.2gf / Texture yarn can be provided, which has excellent properties of excellent warmth, excellent tactile feel due to loop expression, and improved elongation.
그러므로 본 발명에 의하면, 신축성은 물론 스판덱스 특유의 염색 불량, 인체 접촉시 촉감 저하를 해결하여 신도가 우수하고, 스판덱스의 중량감을 극복하여 경량ㆍ보온성의 기능성이 우수하고 루프발현에 의한 촉감을 향상시킨 복합사를 제공하여 활동성, 기능성, 디자인의 측면을 모두 만족하고, 최적의 쾌적감을 발현하는 의류제품을 제조할 수 있으며, 보온은 물론 신축성에 의한 활동성이 우수한 시니어캐주얼용 의류로도 활용할 수 있다.Therefore, according to the present invention, not only stretchability but also spandex unique dyed defects and deterioration of tactile sensation during human contact can be solved, thereby providing excellent stretchability, overcoming the weight of spandex and providing excellent lightweight / warmth- It is possible to manufacture clothing products that satisfy all the aspects of activity, functionality, and design by providing composite yarns and exhibit optimal comfort, and can be utilized as clothing for senior casual wear which is excellent in activity due to stretchability as well as keeping warmth.
