Description
본 발명은 탄력성, 신장성 및 신장 회복성이 우수한 신장성 공기교락사에 관한 것이다.The present invention relates to stretchable air entangled yarn excellent in elasticity, stretchability and stretch recovery.
보다 구체적으로는 모노 데니어(mono denier)의 굵기가 1∼6데니어이고, 총 데니어가 30∼150데니어인 잠재 권축 필라멘트사와 모노 데니어의 굵기가 0.3∼4 데니어이고, 총 데니어가 70∼300데니어인 폴리에스테르 필라멘트사로 구성되어 있는 신장성 공기교락사에 관한 것이다. More specifically, mono denier has a thickness of 1 to 6 denier, latent crimped filament yarn having a total denier of 30 to 150 denier, and 0.3 to 4 denier having a thickness of mono denier, and a total denier of 70 to 300 denier. A stretchable air entangled yarn composed of polyester filament yarn.
신장성을 부여한 가공사는 일반적으로 활동성이 강한 액티브 스포츠(active sport) 용으로 주로 사용되어 왔었으나, 최근에 와서는 패션 소재(素材)로 상당히 많은 인기를 갖게 되어서 정장, 사무복 등 각종 용도로 폭 넓게 사용되고 있는 고가의 원사이다.In general, the stretched yarn has been used mainly for active sports, but recently, it has become very popular as a fashion material and is widely used for various purposes such as suits and office clothes. It is an expensive yarn used.
종래에 가연사를 이용하는 신장성 직물의 제조 방법이 한국 공개 특허 제1992-25482호에 공개된 바 있으나, 이 방법은 가연사의 신장성에 한계가 있기 때문에 직물의 신장성과 신장 회복성을 저하시키는 문제점이 있었다.Conventionally, a method of manufacturing stretchable fabric using twisted yarn has been disclosed in Korean Laid-Open Patent Publication No. 1992-25482, but this method has a problem of lowering stretchability and stretch recovery of the fabric because of limitation in stretchability of the twisted yarn. there was.
또한, 일본 공개특허 특개평6-212525호에는 폴리우레탄(spandex)사를 심사로 하고 방적사를 이펙트사로 하는 신장성 장단섬유 복합 코어얀이 제안되어 있다. 그러나, 이와같은 신장성 장단섬유 복합 코어얀을 사용하여 제직한 원단은 신장성은 양호하지만 몇 가지의 단점을 가지고 있다. In addition, Japanese Laid-Open Patent Publication No. 6-212525 proposes an elongated short-fiber composite core yarn in which a polyurethane (spandex) yarn is used as the screening yarn and the yarn is an effect yarn. However, fabrics woven using such an elongated short fiber composite core yarn have good drawability but have some disadvantages.
먼저 침염으로 염색할 때 110∼130℃의 고온, 습열하에서 스판덱스사의 퍼짐현상(신장성 저하현상)이 발생하며, 이와 같은 현상은 재염이상의 공정에서는 더욱 현저하기 때문에 공정불량률을 증가시키게 된다.First, when dyeing with dip dye, spreading of spandex yarn (deterioration of phenomena) occurs under high temperature and moist heat of 110-130 ° C. This phenomenon is more prominent in the process of re-dyeing, thus increasing the process defect rate.
또한 상기 원단으로 제조한 의류는 착용중 반복되는 텐션으로 인하여 스판덱스사의 늘어짐 현상이 더욱 심하게 발생하는 폐단이 있다.In addition, the garment made of the fabric has a closed end more severely occurs the spandex yarn due to repeated tension during wearing.
또한, 한국 공개 특허 제1996-14443호에 기재된바와 같이 스판덱스, 가연사 또는 잠재 권축사를 사용하지 않고 장단섬유 복합사를 사용한 직물은 염색가공 후에 신장성이 발현되지 않는 단점이 있다.In addition, as described in Korean Patent Laid-Open Publication No. 1996-14443, a fabric using long-short fiber composite yarn without using spandex, false twisted yarn or latent crimped yarn has a disadvantage in that extensibility is not expressed after dyeing.
또한, 한국 공개 특허 특2003-0040287호에 기재된 바와 같이 잠재 권축 필라멘트사와 단섬유를 사용한 심초(Core-Sheath)구조의 장단복합섬유 코어사는 정방기에서 단섬유를 집속시키는데 공정상으로 어려움이 있고 연사공정이 까다로운 단점이 있다.In addition, as described in Korean Patent Laid-Open Publication No. 2003-0040287, a long-short composite fiber core yarn having a core-sheath structure using latent crimped filament yarn and short fibers has difficulty in focusing short fibers in a spinning machine and is twisted. The process has a disadvantage.
따라서, 본 발명의 목적은 잠재 권축필라멘트사가 지니는 고유의 크림프 발현성과 필라멘트사의 효과에 의하여 본 발명에 의한 신장성 공기교락사를 원사로 사용하여 제직, 염가공한 직물은 우수한 탄력성, 드레이프성, 신장성 및 신장 회복성을 가지며 부드러운 표면 터치를 가지도록 하는데 있다. Therefore, the object of the present invention is to use the stretchable air entangled yarn according to the present invention as a yarn by the original crimp expression and filament yarn of latent crimped filament yarn as a yarn, the woven fabric is excellent elasticity, drape, stretchability And stretch recovery and soft surface touch.
본 발명에 의한 신장성 공기교락사는 잠재 권축 필라멘트사와 폴리에스테르 필라멘트사를 사용하여 제조된 것으로서 도면을 참조하여 상세히 설명하면 다음과 같다.The stretchable air entangled yarn according to the present invention is manufactured using latent crimped filament yarn and polyester filament yarn, and will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 신장성 공기교락사의 구성을 나타내는 확대 단면도로서 염가공등 열처리 공정에 의해 권축이 부여되어 수축율이 높은 잠재권축사는 내부에, 폴리에스테르 필라멘트사는 외부에 분포되어 있는 심초형 구조를 나타내고 있다. Figure 1 is an enlarged cross-sectional view showing the configuration of the stretchable air entangled yarn of the present invention, the core crimp is given by the heat treatment process such as salt processing, the latent crimp yarn having a high shrinkage is inside, the polyester filament yarn is distributed outside Indicates.
도 1에서 한 성분의 사(2)는 폴리에스테르계 잠재 권축 필라멘트사로 구성된 것이어야 한다. 상기 사(2)는 모노 데니어의 굵기가 1∼6데니어, 필라멘트사의 총 데니어는 30∼150데니어 이다. 다른 성분의 사(1)는 모노 데니어의 굵기가 0.3∼4데니어, 필라멘트사의 총 데니어는 70∼300데니어인 일반 필라멘트사로 구성된 것이다. 또 잠재 권축 필라멘트사(2)의 일반 필라멘트사(1)에 대한 비율은 무게비로 10∼50%이며, 본 발명에 의한 신장성 공기교락사는 2본의 상기 필라멘트사(1)(2)를 2∼5 kgf/㎡의 공기압으로 교락시킨 것이다.In Fig. 1, the yarn 2 of one component should be composed of polyester-based latent crimped filament yarn. The yarn 2 has a monodenier having a thickness of 1 to 6 deniers and a total denier of filament yarns of 30 to 150 deniers. The yarn 1 of the other component is composed of general filament yarn having a monodenier of 0.3 to 4 denier and a total denier of filament yarn of 70 to 300 denier. In addition, the ratio of the latent crimped filament yarn (2) to the general filament yarn (1) is 10 to 50% by weight ratio, and the extensible air entangled yarn according to the present invention is divided into two pieces of the filament yarn (1) (2) It entangled by the air pressure of -5 kgf / m <2>.
본 발명에서 잠재 권축 필라멘트사(2)의 총 데니어가 30데니어 미만이면 직물로 하였을 때 원단의 신장성이 크게 발현되지 않으며, 잠재 권축 필라멘트사가 150데니어를 초과하면 필라멘트사(1)와 복합하였을 때 중량이 너무 무거워 의류용 원단으로 사용하기에는 적합하지 않다.In the present invention, if the total denier of the latent crimped filament yarn (2) is less than 30 denier, the extensibility of the fabric is not greatly expressed when the fabric is used, and when the latent crimped filament yarn exceeds 150 denier, the composite filament yarn (1) It is so heavy that it is not suitable for use as a garment fabric.
또 잠재권축필라멘트사(2)의 모노데니어가 1데니어 미만이면 탄력감이 저하되고, 6데니어를 초과하면 교락이 잘 되지 않는다. When the monodenier of the latent crimped filament yarn 2 is less than 1 denier, the feeling of elasticity is lowered.
또 일반필라멘트사(1)의 총데니어가 70데니어 미만이면 탄력감이 저하되고, 300데니어를 초과하면 교락이 잘 되지 않으며, 상기 일반 필라멘트사(1)의 모노데니어가 0.3데니어 미만이면 터치는 부드럽지만 강도가 저하되고 내마모성이 취약해지며, 4데니어를 초과하면 뻣뻣한 감때문에 직물용으로 사용하기에는 부적합하다. In addition, when the total denier of the general filament yarn (1) is less than 70 denier, the feeling of elasticity is lowered, and if the total filament yarn (1) exceeds 300 denier, the entanglement is not good, and when the monodenier of the general filament yarn (1) is less than 0.3 denier, the touch is soft. Its strength is poor, its wear resistance is weak, and if it exceeds 4 denier, it is not suitable for use in textiles because of its stiffness.
본 발명에서 사용한 잠재 권축 필라멘트사(2)는 열수축성이 상이한 2종의 폴리머를 사이드-바이-사이드(Side-by-side)형 또는 심초형(Sheath-core) 구조로 복합방사한 후 방사공정이나 연신공정에서 열을 주어서 폴리머간에 수축성차를 일으켜서 물리적으로 코일모양의 크림프(Crimp)를 발현시킨 것이고, 상기 필라멘트사(2)는 스프링의 원리에 의하여 고도의 신장성을 발휘한다.The latent crimped filament yarn (2) used in the present invention is a spinning process after two types of polymers having different thermal contraction properties are spun into a side-by-side type or a sheath-core structure. In the stretching process, heat is applied to cause shrinkage difference between polymers, thereby physically expressing a coil-like crimp, and the filament yarn 2 exhibits high extensibility by the principle of a spring.
상기 잠재권축 필라멘트사(2)는 도 2에 표시된 바와 같이 PET(폴리에틸렌테레프탈레이트, 이하 PET라 함)와 PTT(폴리트리메틸렌테레프탈레이트, 이하 PTT라 함)의 2종의 폴리머로 구성된 사이드-바이-사이드(Side-by-side)형 복합사이다. The latent crimped filament yarn 2 is a side-by-side composed of two polymers, PET (polyethylene terephthalate, hereinafter PET) and PTT (polytrimethylene terephthalate, hereinafter PTT) as shown in FIG. Side-by-side composite yarn.
또한, 본 발명에서 잠재 권축 필라멘트사(2)의 비율은 일반 필라멘트사(1)의 10∼50중량%로 하는 것이 좋다.In the present invention, the ratio of the latent crimped filament yarn 2 is preferably 10 to 50% by weight of the general filament yarn 1.
잠재 권축 필라멘트사(2)의 비율을 10% 이하로 하면 신장성이 크게 발현되지 못하고, 50%를 초과하면 신장성 공기교락사의 표면에 잠재 권축 필라멘트사(2)의 돌출현상이 두드러지게 된다.When the ratio of the latent crimped filament yarn 2 is 10% or less, the extensibility is not largely expressed, and when the ratio of the latent crimped filament yarn 2 is exceeded, the protrusion phenomenon of the latent crimped filament yarn 2 becomes prominent on the surface of the stretchable air entangled yarn.
또한 본 발명에서는 균일한 교락도 획득과 핀사 발생 등을 억제하기 위해 인터레이싱(Interlacing) 시의 공기압은 선택한 사종에 따라 적합하게 설정해야 하며, 모노 데니어가 작고 필라(fila)수가 많은 원사를 사용할 경우에는 2∼3 kgf/㎡, 모노 데니어가 크고 필라수가 적은 원사를 사용할 경우에는 3 kgf/㎡ 이상으로 하는 것이 좋다.In addition, in the present invention, in order to suppress uniform interlocking degree and pin yarn generation, the air pressure at the time of interlacing should be appropriately set according to the selected type, and when a mono denier is used and a yarn with a large number of pillars is used. In the case of using 2 to 3 kgf / m 2, and a yarn having a large monodenier and a small number of pillars, it is preferable to set it to 3 kgf / m 2 or more.
이와 같이 제조된 본 발명에 의한 신장성 공기교락사를 원사로 하여 래피어 직기로 제직하고, 제직된 생지는 내부열 분포를 균등하게 한 열처리기를 이용하여 20∼60초 동안 150∼190℃의 건열로 셋팅하면서 열처리 전 포지에 비해 20%내로 확포시키고, 오버 피드율은 3∼25% 범위로 조절하고, 통상의 방법으로 염색 및 가공을 한 다음, 다시 20∼60초 동안 150∼190℃에서 형태안정화를 위한 건열 셋팅을 하였다. The stretched air entangled yarn according to the present invention manufactured as described above is woven into a rapier loom, and the woven dough is dried with a heat of 150 to 190 ° C. for 20 to 60 seconds using a heat treatment machine that equalizes the internal heat distribution. While setting, spread the paper within 20% compared to the paper before heat treatment, adjust the overfeed rate in the range of 3-25%, dye and process in the usual way, and then stabilize the form at 150-190 ° C for 20-60 seconds. Dry heat setting for.
건열 셋팅 온도가 150℃ 미만이면 형태안정화 셋팅이 미흡하게 되며, 190℃ 를 초과하면 가공후의 신장성이 저하되고, 촉감 또한 소프트하지 못하게 된다. 또 열처리 시간이 20초 미만이면 셋팅이 미흡하며, 60초를 초과하면 포지의 신장성이 저하되고 촉감 또한 소프트하지 않게 된다. If the dry heat setting temperature is lower than 150 ° C, the shape stabilization setting is insufficient. If the dry heat setting temperature is higher than 190 ° C, the elongation after processing is lowered, and the touch is also not soft. If the heat treatment time is less than 20 seconds, the setting is insufficient. If the heat treatment time is longer than 60 seconds, the extensibility of the forge decreases and the touch is not soft.
본 발명의 신장성 공기교락사로 제직한 생지는 상기한 바와 같이 염색가공을 하면 30∼50%의 신장율과 잠재 권축 필라멘트사 고유의 크림프가 발현됨과 동시에 외부에 있는 폴리에스테르 필라멘트사로 인하여 90% 이상의 신장회복율을 가지며 우수한 드레이프성과 부드러운 촉감을 가지게 된다. Dough woven with the stretchable air entangled yarn of the present invention, when the dyeing process as described above, the elongation of 30-50% and the original crimp of the potential crimped filament yarn is expressed and at least 90% elongation due to the external polyester filament yarn It has recovery rate and excellent drape and soft touch.
또한, 본 발명에 사용되는 잠재 권축 필라멘트사(2)는 PET, PTT 2종 폴리머로 구성되어 있는 복합사로써, PTT는 PET에 비하여 염가공시 20℃ 정도 낮은 온도에서도 농색발현이 가능하고, 분자구조적으로 모듈러스가 낮으므로 PET에 비하여 더 소프트하므로 염색성 및 소프트성이 더욱 우수하다.In addition, the latent crimped filament yarn (2) used in the present invention is a composite yarn composed of two kinds of PET and PTT polymers, and PTT is capable of deep color expression at a temperature as low as 20 ° C. when processing the salt, compared to PET. As the modulus is low, it is softer than PET, so it is more excellent in dyeing and softness.
