본 발명은 태섬도섬유가 혼섬사의 심부(core)에 존재하며 세섬도사가 이펙트사(effect사)로 존재하는 폴리에스터 이수축혼섬사 및 그 제조방법에 관한 것으로서, 더욱 구체적으로는 고수축특성을 갖는 태섬도사는 코어사로, 저수축특성을 갖는 세섬도사는 이펙트사로 되어 있는 폴리에스터 이수축혼섬사 및 그 제조방법에 관한 것이다.The present invention relates to a polyester di-shrink horn filament yarn and a method of manufacturing the same, in which the core fiber is present in the core of the horn filament yarn and the fine fiber is present as the effect filament yarn. The Taesumdo yarn is a core yarn, and the finer shrinkage yarn having a low shrinkage property relates to a polyester bishrink blended yarn which is made of an effect yarn, and a manufacturing method thereof.

종래의 폴리에스터 이수축혼섬사 및 그 제조방법들은 다음과 같다.Conventional polyester biaxially blended yarn and its manufacturing method are as follows.

첫째 수축특성이 상이한 두 종류의 폴리머를 같은 방사팩내의 각각의 유로를 경유시켜서 방사하여 제조한 복합방사방법에 의한 것과, 둘째 수축특성이 상이한 두 종류의 폴리에스터 미연신사를 연신기에서 합연신시켜 제조한 합연신방식에 의한 것과, 셋째 수축특성이 상이한 두 종류의 폴리에스터 연신사를 공기교락 등의 방법으로 합사시켜 제조한 합사방식에 의한 것으로 대별될 수 있다.First, the composite spinning method was produced by spinning two polymers with different shrinkage characteristics through respective flow paths in the same spinning pack, and secondly, two kinds of polyester unstretched yarns having different shrinkage characteristics were drawn together in the drawing machine. It can be roughly classified into two types of polyester drawn yarns having different shrinkage characteristics from those made by a jointed drawing method.

상기한 바와 같은 종래의 폴리에스터 이수축혼섬사 및 그 제조방법들은 복잡한 제조설비를 요하거나 제조단계가 복잡하기 때문에 제조원가면에서 불리할 뿐만 아니라 균일한 물성의 사를 제조하기에는 부적합하였다.Conventional polyester biaxially blended yarn and its manufacturing method as described above is not only disadvantageous in terms of manufacturing cost, but also inadequate for producing a uniform physical properties because of the complicated manufacturing equipment or complicated manufacturing steps.

또 상기 종래의 폴리에스터 이수축혼섬사는 고수축사와 저수축사가 동일방사 구금에서 랜덤하게 방사되기 때문에 서로 간섭되어 조업성이 떨어질 뿐 아니라 혼섬사내에 두 종류의 사가 랜덤하게 분포되어 있기 때문에 이수축혼섬에 의한 부드러운 촉감발현에는 한계가 있었다.In addition, since the conventional polyester biaxially blended yarns are randomly radiated in the same spinning cap, high shrink yarns and low-shrink yarns are not only interfering with each other, and thus the operation is inferior. There was a limit to the soft hand expression.

왜냐하면 혼섬사에서 촉감 등 그 외관효과에 영향을 주는 부분은 표면에 존재하는 사 인바, 종래의 혼섬사는 부드러운 촉감을 발현시키는 사 만이 표면에 독점되지 않고 다른 사도 혼재되어 있기 때문에 부드러운 촉감의 발현을 최대화 할 수 없는 것이다.Because the part that affects the appearance effect such as touch in the blended yarn is a sine that exists on the surface, the conventional blended yarn maximizes the appearance of soft touch because only the yarn that expresses the soft touch is not monopolized on the surface and mixed with other yarns. It can't be done.

본 발명은 상술한 바와 같은 문제점을 해결한 것으로서 이하 예시도면에 의거 상세히 설명하면 다음과 같다.The present invention solves the above problems as described above in detail based on the exemplary drawings as follows.

본 발명은 제2도에 표시한 바와 같이 직경이 큰 구금공부분(A)과 직경이 작은 구금공부분(B)이 양분되어 있되 직경이 큰 구금공부분(A)이 냉각장치(2)와 가까운 위치에 배열된 방사구금(1)을 사용하여 고유점도가 0.62인 폴리에틸렌테레프탈레이트를 용융방사하여 제1도에 도시한 바와 같은 제조공정을 경유해서 폴리에스터 이수축혼섬사를 제조한다.According to the present invention, as shown in FIG. 2, the large diameter hole part A and the small diameter hole part B are divided into two parts, but the large diameter hole part A is divided into the cooling device 2 and the cooling device 2. A polyester biaxially blended yarn is produced by melt spinning a polyethylene terephthalate having an intrinsic viscosity of 0.62 using a spinneret (1) arranged at a close position through a manufacturing process as shown in FIG.

더욱 구체적으로 설명하면 태섬도사(Y1)는 냉각풍과 가깝게 방사되고 세섬도사 (Y2)는 냉각풍으로 부터 먼위치로 방사되도록 한다.More specifically, the Taeseomsa yarn (Y 1 ) is radiated closer to the cooling wind and the finer island (Y 2 ) is to be radiated to a position far from the cooling wind.

이렇게 되면 냉각, 고화영역에서 세섬도사(Y2)에 미치는 냉각풍의 온도는 태섬도사(Y1)에 미치는 온도보다 높게 된다.In this case, the temperature of the cooling wind on the fine sum yarn (Y 2 ) in the cooling and solidifying region is higher than the temperature on the fine island yarn (Y 1 ).

그 결과 세섬도사(Y2)는 결정화도가 높아지게 되는 반면에 태섬도사(Y1)는 결정화도가 낮아진다.As a result, the finer yarn (Y 2 ) has a higher degree of crystallinity while the finest yarn (Y 1 ) has a lower degree of crystallinity.

그러므로 세섬도사(Y2)는 수축율이 적어지는 반면에 태섬도사(Y1)는 수축율이 커지게 되는 것이다.Therefore, the finer yarn (Y 2 ) has a smaller shrinkage rate, while the finer yarn (Y 1 ) has a larger shrinkage rate.

아울러 냉각풍에 의하여 세섬도사(Y2)는 태섬도사(Y1)보다 블로잉(Blowing)곡율이 커져서 두 사(Y1),(Y2)가 서로 분리되어 서로간의 간섭이 배제되기 때문에 본 발명은 세섬도사(Y2)와 태섬도사(Y1)가 혼재된 상태로 용융방사되는 경우보다 조업성면에서 매우 우수하다.In addition, the three fine yarns (Y 2 ) are blown (Blowing) curvature of the two fine yarns (Y 1 ) due to the cooling wind, so that the two yarns (Y 1 ), (Y 2 ) are separated from each other and the interference between them is excluded. Silver is much better in terms of operation than when melt-spun in the state of seomdosa (Y 2 ) and Taeseomsa (Y 1 ) mixed.

상기 두 종류의 사(Y1),(Y2)를 오일링롤(3)에서 오일링 한 다음에 제1고뎃롤(4)과 제2고뎃롤(5) 사이에서 연신한 후 인터레이서(6)로 공기교락시키고 권취기(7)에서 권취한다.After the two kinds of yarns (Y 1 ) and (Y 2 ) are oiled in the oil ring roll (3), the interlacer (6) is drawn between the first gourd roll (4) and the second gourd roll (5). ) Air-wound and wound in a winder (7).

본 발명에서 태섬도사(Y1)는 35데니어가 되게 하고 세섬도사(Y2)는 0.41데니어가 되게 하였다.Taeseodosa in the present invention (Y 1 ) is 3 5 denier and fine fine thread (Y 2 ) is 0.4 It became 1 denier.

만일 세섬도사(Y2)의 섬도가 0.4데니어 미만이면 연신중 절사가 많아서 조업성이 떨어지고, 1데니어 보다 크면 비등수수축율차이를 3이상이 되게 하기가 곤란하다. 또 태섬도사(Y1)의 섬도는 고수축특성을 높이고 세섬도사(Y2)와의 연신성 균형을 고려하여서 35데니어로 하는 것이 적당하였다.If the fineness of the three fine yarns (Y 2 ) is less than 0.4 denier, there is a lot of cutting during stretching, resulting in poor operability. It is difficult to make abnormal. In addition, the fineness of Taesum Dosa (Y 1 ) increases the high shrinkage characteristic and takes into account the elongation balance with Sesum Dosa (Y 2 ). It was appropriate to use 5 deniers.

본 발명에서는 세섬도사(Y2)의 결정화도를 높여서 비등수수축율이 최대가 되도록 하기 위하여 최대연신배율의 90이상으로 연신하였다.In the present invention, in order to increase the degree of crystallinity of the finer fine yarn (Y 2 ) so that the boiling contraction rate is maximum, 90 of the maximum draw ratio is obtained. It extended | stretched above.

이렇게 하면 세섬도사(Y2)와 태섬도사(Y1)간의 비등수수축율차이를 3이상으로 유지시킬 수 있다.This reduces the difference in boiling contraction rate between sesame island sand (Y 2 ) and Taesum island sand (Y 1 ). The above can be maintained.

위 식에서,In the above formula,

ℓ0: 0.1g/d의 하중하에서 측정한 길이ℓ 0 : length measured under a load of 0.1 g / d

ℓ1: 100℃의 물에서 무장력상태로 15분간 수축시킨 다음 ℓ0방법과 동일하게 측정한 길이ℓ 1 : Shrink in water at 100 ℃ for 15 minutes without tension and measure the same length as ℓ 0 method

본 발명은 폴리에스터 이수축혼섬사를 특별한 장치없이 구금공의 배치를 변경시켜 경제적으로 제조할 수 있는 장점이 있다.The present invention has the advantage that it can be economically produced by changing the arrangement of the ball-hole polyester bishrink blended yarn without a special device.

본 발명의 폴리에스터 이수축혼섬사는 직, 편한후 열수나 스팀으로 수축시키면 제3도와 같이 고수축성 태섬도사(Y1)는 심사로 되고 저수축성 세섬도사(Y2)는 이펙트사가 된다.When the polyester di-shrink blended yarn of the present invention is woven and comfortable, and is shrunk with hot water or steam, the highly shrinkable taysum yarn (Y 1 ) becomes a screening and the low-shrinkable fine-grained yarn (Y 2 ) becomes an effect yarn as shown in FIG. 3.

또 본 발명의 이수축혼섬사는 상술한 바와 같이 두 사(Y1),(Y2)간의 비등수축율차이가 3이상이며 태섬도사(Y1)의 총섬도 대 세섬도사(Y2)의 총섬도의 비가 1 : 12 : 1이다.In addition, as described above, the heteroshrink mixed fiber of the present invention has a difference in boiling shrinkage between the two yarns (Y 1 ) and (Y 2 ) of 3 This is the ratio of total fineness of Taesumdo-sa (Y 1 ) to total fineness of Sesom-do-sa (Y 2 ) 1: 1 2: 1

본 발명에서 태섬도사(Y1)의 총섬도의 비가 1보다 적으면 제사성 및 조업성 면에서 어려움이 많으며 2보다 크면 이수축혼섬사의 표면촉감이 불량해진다.In the present invention, if the ratio of the total fineness of the Taisumdosa (Y 1 ) is less than 1, there are many difficulties in terms of sacrificial and operability, and if it is greater than 2, the surface feel of the bishrinkage blended yarn is poor.

본 발명의 폴리에스터 이수축혼섬사는 세섬도사가 이펙트사로 되어 있으므로 매우 부드러운 촉감을 나타낸다.The polyester heteroshrink blended yarn of the present invention exhibits a very soft touch because the finer yarn is made of effect yarn.
