B : 세그멘트(제2성분)B: segment (second component)

본 발명은 섬유형성성 폴리에스터와 섬유형성성 폴리아미드를 각각 제1성분과 제2성분으로 하고 있으며, 제2성분이 복합사의 횡단면의 중심부로부터 외곽쪽을 향하여 쐐기형태로서 배열되어 있고 제1성분이 상기 제2성분 사이에 교호로 배열되어 있는 분할형 복합사에 관한 것이다. 더욱 구체적으로 설명하면 본 발명은 제1성분이 복합사 횡단면의 중심부분에 소원(小圓)형태의 부분과 이로부터 복합사 횡단면의 외곽을 향하여 방사상으로 뻗어있는 가지(Branch)부분을 이루고 있고 이들 가지사이에 제2성분 세그멘트(Segment)들이 쐐기모양으로 배열되어 있으며, 상기 세그멘트들이 물리적 또는 화학적인 처리에 의하여 분리될 수 있도록 되어 있는 분할형 복합사에 관한 것이다.In the present invention, the fiber-forming polyester and the fiber-forming polyamide are the first component and the second component, respectively, and the second component is arranged in a wedge shape from the center of the cross section of the composite yarn toward the outer side, and the first component. It relates to a divided composite yarn alternately arranged between the second components. More specifically, in the present invention, the first component forms a wish-shaped portion at the central portion of the cross section of the composite yarn and a branch portion extending radially toward the outside of the cross section of the composite yarn. A second component segment is arranged in a wedge shape between branches, and the segment is a split composite yarn which can be separated by physical or chemical treatment.

본 발명의 특징은 복합사를 구성하고 있는 제1성분과 제2성분 세그멘트의 형상을 특정한 형태를 갖도록 함과 동시에 특정한 조건을 만족하도록 하여 분리시 제2성분 세그멘트들의 분리도를 높이고 각 복합사들간의 분리도의 차이가 15% 이하가 되도록 한 점에 있다. 본 발명에서 말하는 분리도와 분리도 차이는 스핀들 타입의 가연기로 가연하여 복합사를 분리시킬 경우의 분리된 정도를 다음의 식으로 계산한 것이다.A feature of the present invention is to make the shape of the first component and the second component segment constituting the composite yarn to have a specific shape and at the same time to satisfy the specific conditions to increase the separation of the second component segment and the separation between the composite yarn The difference is at the point of 15% or less. The difference in the degree of separation and the degree of separation referred to in the present invention is calculated by the following equation for the degree of separation when the composite yarn is separated by burning with a spindle-type combustor.

종래의 분할형 복합사는 일본 특허공고번호 소 53-38764, 일본 특허공고번호 소 58-5311 및 일본 공개 특허번호 소 51-60769로 알려진 바와같이 제2a도-제2d도와 같은 횡단면 형태를 갖는 것들이었다. 이들 중에서 제2a도, 제2c도 및 제2d도에 표시된 것들은 두성분의 접합면이 평면으로 되어 있음을 알 수 있는 바, 이들은 모두가 비교적 분리도가 낮고 분리도의 차이는 매우 큼을 알 수 있다.(표1. 참조)Conventional split composite yarns have cross-sectional shapes such as FIGS. 2A-2D as known from Japanese Patent Publication No. 53-38764, Japanese Patent Publication No. 58-5311, and Japanese Patent Publication No. 51-60769. . Among them, those shown in FIGS. 2a, 2c, and 2d show that the joining surfaces of the two components are planar, and they all show relatively low separation and very large difference in separation. See Table 1.

그리고 제2b도의 복합사는 두 성분으로 되어 있는 세그멘트들의 접합면이 곡면으로 되어 있음을 알 수 있는데, 이것의 분리도는 그와 유사한 단면형태를 갖는 제2c도의 것과 비교하여 분리도가 높고 분리도 차이도 적음을 알 수 있다. 그러나, 제2b도의 복합사는 분리도의 개선 정도가 미미하고, 단면이 복잡한 관계로 연신 작업성등이 좋지 못한 단점이 있다. 그런데, 분할형 복합사를 사용하여 고밀도직물이나 인공피혁을 제조할 때, 세그멘트들의 분리도가 낮으면 기대하였던 바와같은 고밀도의 직물을 얻기가 어려우며, 천연피혁에 흡사한 인공피혁을 제조할 수 없고 또, 유연한 촉감을 갖는 제품을 만들 수 없다는 것은 잘 알려진 사실이다. 또한, 각 복합사들간의 세그멘트의 분리도의 차이가 크면, 균일하게 염색된 제품을 얻을 수 없다.In addition, it can be seen that the composite yarn of FIG. 2b has a joint surface of segments composed of two components, and the degree of separation thereof is higher than that of FIG. 2c having a similar cross-sectional shape, and the separation degree is small. It can be seen. However, the composite yarn of FIG. 2b has a disadvantage in that the degree of improvement in separation is insignificant, and the drawing workability is poor due to the complicated cross section. However, when manufacturing high-density fabric or artificial leather using split composite yarns, it is difficult to obtain high-density fabrics as expected when the separation of segments is low, and artificial leather similar to natural leather cannot be manufactured. It is a well-known fact that it is not possible to make a product with a flexible touch. In addition, if the difference in the degree of separation of the segment between the composite yarn is large, it is not possible to obtain a uniformly dyed product.

즉, 염색된 고밀도직물 혹은 인공피혁의 표면에서 분리가 많이 된 부분은 밝게(light) 염색되어 나타나고, 분리가 적게 일어난 부분은 어둡게(Dark) 염색되어 나타나므로 분리도의 차이가 큰 복합사로 제조한 고밀도직물이나 인공피혁은 염색 후에 위사간에 색의 차이가 발생하며, 분리도의 차이가 크면 클수록 이와 같은 결점은 크게 나타나게 된다.In other words, the areas where the separation is high on the surface of the dyed high-density fabric or artificial leather appear lightly dyed, and the parts where the separation is less appear dark dyed. In the case of textile or artificial leather, the color difference occurs between the weft yarns after dyeing, and the larger the difference in separation, the larger the defects.

본 발명자들은 이와같은 사실에 근거하여 두성분의 접합면을 곡면으로 하고, 복합사의 횡단면형태가 특정한 조건을 만족하도록 함으로써 우수한 품질의 고밀도 직물, 또는 인공피혁을 제조할 수 있는 분할형 복합사를 발명하게 되었다.The inventors of the present invention have invented a split composite yarn capable of producing a high-density fabric or artificial leather of excellent quality by making the joint surface of two components curved and making the cross-sectional shape of the composite yarn satisfy specific conditions. Was done.

본 발명을 상세히 설명하면 다음과 같다. 섬유형성성 폴리에스터와 섬유형성성 폴리아미드를 각각 제1성분과 제2성분으로 하고 있으며, 제1성분이 복합사 횡단면의 중심부분에 소원(小圓)형태의 부분(A1)과 이로부터 복합사 횡단면의 외곽을 향하여 방사상으로 뻗어 있는 가지부분(A2)을 이루고 있으며, 이들 가지(A2)사이에 제2성분으로 되어 있는 세그멘트(B)들이 쐐기모양으로 배열된 분할형 복합사에 있어서, 복합사횡단면의 전체 면적에 대한 세그멘트(B)들의 합계 면적비율이 60-80%를 차지하고 있고, 가지(A2)와 세그멘트(B)간의 접합면이 곡면을 이루고 있으며, 복합사 횡단면의 직경(R)에 대한 소원부분(A1)의 직경(r)과의 비와 가지(A2)의 가장 바깥쪽 부분의 폭(a)에 대한 가지(A2)의 최대폭(b)의 비가 각각 다음의 식(1)과 (2)를 만족하는 것이다.The present invention is described in detail as follows. The fibrous polyester and the fibrous polyamide are composed of the first component and the second component, respectively, and the first component is a wish-shaped portion (A 1 ) from the central portion of the cross section of the composite yarn, and Branched yarns (A 2 ) extending radially toward the outside of the cross-section of the composite yarn, and segments (B) of the second component between these branches (A 2 ) in a wedge-shaped split composite yarn In this case, the total area ratio of the segments (B) to the total area of the composite yarn cross section occupies 60-80%, and the joint surface between the branches (A 2 ) and the segment (B) forms a curved surface. diameter (r) of a wish part (a 1) with a diameter (r) the maximum width of the ratio and of (a 2) of (a 2) to the width (a) of the outermost part of the (b) for the ratio The following expressions (1) and (2) are satisfied.

본 발명에서 세그멘트(B)들의 합계면적 비율이 60%보다 적게 되면, 방사 후, 연신할 때 세그멘트(B)들이 분리되므로 연신작업성이 불량해지며, 80%를 초과하면 제1도에 표시한 바와같은 횡단면 형태를 갖는 본 발명 복합사를 만들 수 없게 된다. 한편, b/a의 값이 2보다 크면 세그멘트를 분리시킬 때, 분리가 매우 불균일하게 일어나서 염색한 제품의 위사방향으로 염색차이를 일으키기가 쉽고, 4/3보다 적으면 제2A도에 표시한 횡단면 형태를 가지게 되어 본 발명에서 기대하는 효과를 얻을 수 없다.In the present invention, if the total area ratio of the segments (B) is less than 60%, since the segments (B) are separated after stretching, the stretching workability is poor, and if it exceeds 80% is shown in FIG. The composite yarn of the present invention having the cross-sectional shape as described above cannot be produced. On the other hand, when the value of b / a is greater than 2, when the segment is separated, the separation is very non-uniform, and it is easy to cause dyeing difference in the weft direction of the dyed product, and when less than 4/3, the cross section shown in FIG. 2A It has a form can not obtain the effect expected in the present invention.

또, r/R의 값이 1/10보다 적으면 세그멘트(B)의 안쪽부분이 너무 가늘어져 분리도차의 원인이 되며, 1/5 이상이 되면 연신할 때, 세그멘트(B)들이 분리되어 연신작업성이 떨어진다. 본 발명의 분할형 복합사는 위에서 설명한 바와같이 세그멘트(B)들을 분리시킬 때, 분리도가 좋고 분리도의 차이가 적기 때문에 외관과 촉감이 우수한 고밀도의 직물 또는 편물, 인공피혁, 고기능성 와이퍼(Wiper) 및 클리너의 제조용으로 사용할 수 있으며, 종래의 분할형 복합사와는 달리 균일한 염색이 가능하다.In addition, if the value of r / R is less than 1/10, the inner part of the segment B is too thin, which causes the separation difference, and when it is 1/5 or more, the segments B are separated and stretched. Poor workability When the divided composite yarn of the present invention separates the segments (B) as described above, the separation and the degree of separation is small, the high density fabric or knitted fabric having excellent appearance and feel, artificial leather, high functional wiper and It can be used for the manufacture of a cleaner, and unlike the conventional divided composite yarns, uniform dyeing is possible.
