Abstract

The polyester multifilaments fabric is made by weaving the weft yarn obtained by: doubling the twisted yarn having T/M of C (where C is 1600-3200 T/M) and the twistless yarn; twisting again the doubled yarn with the T/M of D in the opposite twisting direction to that of C-twisted yarn, so that the condition satisfies the equation of 1/3 < D/C < 3/4. The fabric woven from the above weft yarn has improved differential-shrinkage effect and unique appearance both of which are possible by utilizing the difference of fiber length between two yarns.

Description

이수축 혼섬사 직물의 제조방법Manufacturing method of double shrink blended yarn

본 발명은 폴리에스터 멀티필라멘트사에 의한 이수축 혼섬사 직물의 제조방법에 관한 것이다.The present invention relates to a method for producing a biaxial blended yarn fabric by polyester multifilament yarns.

구체적으로는 이수축 혼섬사의 이수축 효과를 향상시키면서 특이한 외관을 갖게 하기 위한 위사의 제조에 관한 것이다.More specifically, the present invention relates to the production of a weft yarn for giving a specific appearance while improving the bishrinkage effect of the bishrinkage honsum yarn.

1980년대부터 일반화된 이수축 혼섬사는 그 효과를 증대시키고 벌키성을 강조한 루프(Loop)형 이수축사가 다수 상품화되어 새로운 합섬의 대표적 아이템으로 시장을 형성하고 있다.Since the 1980s, Isu-San Hon-Sum, which has increased its effectiveness and emphasized bulkyness, has been commercialized as a number of Loop-type I-Su Tong, which is forming a market as a representative item of new HIM.

이러한 폴리에스터 이수축 혼섬사는 심부(心部)를 형성하는 고수축사와 초부(初部)를 형성하는 저수축사로 구성되어 주로 직물의 경사에 적용되며, 위사로는 품목에 따라 다르지만 주로 일반적인 폴리에스터 필라멘트사의 중연(中撚) 또는 강연사가 적용되어 포지의 반발특성 및 드레이프성 등에 영향을 미치게 되는 정도로서 기존의 위사의 역할 이외의 이수축 혼섬의 효과를 증대시키는 역할은 수행치 못하는 실정이었다.These polyester biaxially blended yarns consist of high shrink yarns that form the core and low shrink yarns that form the core, and are mainly applied to the warp of the fabric. As the filament yarn's medium or twisted yarn was applied to affect the repulsion characteristics and drape of the forge, it was not possible to increase the effect of the diaxial horn fiber other than the existing weft yarn.

즉, 종래에 사용한 위사는 폴리에스터 섬유를 1,500∼3,000T/M으로 연사한 것을 사용하거나 1,000∼2,000T/M으로 연사한 후 이를 합사하여 동일 연으로 1,000∼2,000T/M으로 재연사한 것을 사용하였다.In other words, the weft yarn used in the prior art is used by twisting the polyester fiber at 1,500 ~ 3,000T / M, or it is twisted at 1,000 ~ 2,000 T / M and then re-twisted at 1,000 ~ 2,000 T / M in the same Used.

그러나 이러한 형태의 위사는 종래의 일반적인 위사의 역할밖에 수행할 수 없어서 벌키성의 향상에 기여하지 못했다.However, this type of weft can only perform the role of a conventional general weft, and contributed to the improvement of the bulkiness.

이에 본 발명자들은 경사에 적용되는 이수축 혼섬사의 효과를 증대시키면서 기존의 위사역할을 할 수 있는 새로운 위사의 개발에 착하여 본 발명에 이르게 된 것으로 2개의 실을 합사하여 위사로 사용하게 되는데 2종 원사간의 섬유길이의 차를 발생시킴에 따른 효과를 얻도록 한 것이다.Accordingly, the present inventors have come to the present invention by developing a new weft yarn that can serve as an existing weft yarn while increasing the effect of the biaxial horn sum yarn applied to an inclination. The effect of generating a difference in fiber length between yarns is to be obtained.

이하 본 발명은 상세한 내용은 다음과 같다.Hereinafter, the present invention will be described in detail.

일반적으로 개량된 이수축 혼섬사를 경사로 사용함에 있어서는 위사에 적용하는 원사의 직물내의 단면 배열형태를 불균일화시킴으로써 제직후 염가공공정, 특히 정련축소시 부분적으로 미세한 불균일 수축을 부여하여 최종 가공지상에 미세하고 불규칙하게 오글쪼글한 잔주름을 발생시켜 전체적인 벌키성을 향상시킬 수 있는 것이다.In general, in the use of an improved biaxial intertwined yarn as a warp yarn, the cross-sectional arrangement in the fabric of the yarn applied to the weft is uneven, thereby giving a partial non-uniform shrinkage during the dyeing process after weaving, especially in the refining shrinkage, and thus on the final processing ground By generating fine and irregular ragged wrinkles can improve the overall bulkiness.

이러한 불균일 단면의 원사제조는 2종의 원사(이하 A 원사와 B원사로 표현하기로 한다) A와 B로 이루어지는데 A와 B는 필라멘트 1본의 섬도가 1∼2데니어로서 총섬도는 50∼150데니어로 후술하는 합사공정후 위사의 섬도로 적정하였다.This non-uniform cross-section yarn is made of two kinds of yarns (hereinafter referred to as yarns A and B) A and B. A and B have 1 to 2 deniers of 1 filament and 50 to 3 fineness. 150 deniers were titrated with weft yarn after the weaving step described later.

이때 A 원사를 1,600∼3,200 사이의 일정한 꼬임 C T/M을 부여하고 통상의 연지공정(꼬임을 당한 원사가 원상태로 회복하려는 성질을 제거하는 공정)을 행하는데 1,600 미만의 연수는 이후 반감하는 연수를 감안할 때 반발력의 저하가 심하였고, 또한 3,200 이상은 연사공정의 작업성이 좋지 않았다.At this time, yarn A is given a constant twisted CT / M between 1,600 and 3,200, and a normal softening process (a process of removing the nature of the twisted yarn to recover to its original state) is performed. Considering this, the repulsive force was severely reduced, and more than 3,200 did not have good workability of the twisting process.

이렇게 연지된 A 원사와 무연상태(꼬이지않은 상태)의 B 원사를 합사하여 연사기를 이용, 연사함에 있어서 작업성을 감안하여 100T/M 이하의 기본연수(撚數)로 합연공정을 거친 후 A 원사의 꼬임방향의 반대방향으로 D T/M으로 연사한다.In this way, the yarn A and the unleaded (twisted) yarn B are spliced together using a twisting machine. Continuously twist with DT / M in the opposite direction of twist.

이때 D T/M은 C T/M의 절반수준에서 설정함이 좋은데 단, D가 C의 1/3 이하가 되면 심부름 형성하는 B 원사의 연수가 부족하여 원단의 반발특성이 저하되며 3/4 이상이 되면 연지되었던 A 원사의 꼬임이 풀리면서 크림프(crimp)가 살아나 제직시의 해사성이 불량하였다.At this time, DT / M should be set at half level of CT / M. However, if D is less than 1/3 of C, the number of yarns for errand B yarn is insufficient. When the yarn A which was opened was released, the crimp survived and the maritime property of weaving was poor.

즉, 본 발명에서는 연사공정에서 발생하는 연축에 의한 섬도증대(섬유길이 감소)가 된 것이 미연사된 원사와의 합사후 반대 방향으로의 연사시에 다시 회복됨으로써 2종 원사간의 섬유길이의 차이를 발생시키는 것이 본 발명의 요지이다.That is, in the present invention, the fineness increase (reduced fiber length) due to the soft shrinkage occurring in the twisting process is recovered again when the yarn is twisted in the opposite direction after weaving with the non-twisted yarn, thereby reducing the difference in fiber length between the two yarns. Generating is the gist of the present invention.
