본 발명의 이용성(易溶性) 폴리머가 복합섬유 횡단면의 중심부로 부터 외곽부로 향하여 6개 이상의 분지(分枝)를 형성토록 하고, 분지사이에 섬유형성성 폴리머를 교호로 배열시킨 후 복합섬유 횡단면의 외주부분을 이용성 폴리머로 감싸도록 하여서 이용성 폴리머로 구성되는 분지들과 외주부가 상호단절되지 않고 연결되어 있는 극세 사용 복합사에 관한 것으로서, 본 발명의 극세사용 복합사는 직, 편하거나 부직포로 만든 다음에 화학적처리를 하여 이용성 폴리머를 제거함으로써 섬유형성성 폴리머만 남게 되는 것이다.The water-soluble polymer of the present invention is allowed to form at least six branches from the center of the composite fiber cross section toward the outer portion, and after the fiber-forming polymers are alternately arranged between the branches, The outer periphery of the present invention relates to a micro-use composite yarn in which branches made up of the usable polymer and the outer periphery are connected to each other without being disconnected. The micro-use composite yarn of the present invention is made of woven, comfortable or nonwoven fabric. The chemical treatment removes the usable polymer, leaving only the fibrous polymer.

일본 특허공고 소 60－29771등에 보이는 폴리아미드－폴리에스터계 복합섬유는 다수의 폴리머통로를 통하여 제1성분을 토출하고 그 사이의 스리트를 통하여 제2성분을 유입시킴으로써 얻어진다.The polyamide-polyester-based composite fibers shown in Japanese Patent Publication No. 60-292777 and the like are obtained by discharging the first component through a plurality of polymer passages and introducing the second component through the slits therebetween.

그리고 위와 같이 얻어진 복합섬유를 직,편하여서 인공피혁내지는 고밀도 직물등을 제조하게 된다. 그러나, 폴리아미드와 폴리에스터를 복합방사하여 제조한 제2도에 표시한 바와같은 종래의 복합섬유는 기계적, 또는 화학적방법으로 분리되어 제3도에서와 같은 극세섬유로 되지만, 가연, 기모등의 기계적 분리방법을 사용하는 경우에 분리도가 서로 달라서 염색반의 원인이 될 수 있으며 이와같은 현상은 벤질알코올등을 사용하여 화학적방법으로 분리하는 경우에도 마찬가지이다.And the composite fiber obtained as described above by direct, comfortable to produce a high-density fabric, such as artificial leather. However, the conventional composite fibers as shown in FIG. 2 prepared by the complex spinning of polyamide and polyester are separated by mechanical or chemical methods to form the ultrafine fibers as in FIG. In the case of using a mechanical separation method, the degree of separation may be different, which may cause staining. Such a phenomenon may also be applied to chemical separation using benzyl alcohol and the like.

또한 직,편시에 세그먼트들이 분리현상으로 인한 모우의 발생때문에 직,편직 효율이 저하되며, 두 성분이 분리된 상태로 공존하거나, 한 성분을 용해시켜서 분리하는 경우에 있어서도 용해가 완전히 이루어지지 않으면 폴리아미드와 폴리에스터간의 염색성의 차이 때문에 농색염색이 어렵고, 견뢰도가 저하되는 문제점이 있었다. 또한 부직포를 제조할 때 카딩, 크림핑공정에서 복합사의 분리현상이 발생하기 때문에 현재까지 위 복합사로는 부직포의 제조가 불가능한 것으로 알려지고 있다.In addition, the efficiency of weaving and knitting is reduced due to the occurrence of wool due to the separation phenomenon at the time of weaving and knitting, and even if two components are coexisted in a separated state or one component is dissolved and separated, the poly Due to the difference in dyeability between amide and polyester, deep dyeing is difficult, and the fastness is deteriorated. In addition, since the separation phenomenon of the composite yarn occurs in the carding and crimping process when manufacturing the nonwoven fabric, it is known that the nonwoven fabric cannot be manufactured with the above composite yarn.

본 발명은 상술한 바와같은 종래 기술의 문제점을 해결한 것으로, 본 발명은 제1성분으로 이용성 폴리머를 사용하여 복합사 횡단면의 중심부에서 외곡부로 6개 이상의 분지를 형성하도록 하고, 그 사이에 섬유셩성성 폴리머인 제2성분을 교호로 배열시키되, 복합사 횡단면의 외주부에 제1성분인 이용성 폴리머를 유입시켜 외주부를 완전히 둘러싸게 한 후, 후공정에서 이용성 폴리머가 화학적처리를 통하여 완전히 제거되도록 함으로써 섬유형성성 폴리머만으로 되어 있는 극세사를 제조할 수 있도록 한 것을 특징으로 하는 것이다.The present invention solves the problems of the prior art as described above, the present invention is to use a polymer soluble as the first component to form six or more branches from the center of the cross section of the composite yarn to the sulcus, between the fibers By arranging the second component, which is a polymer, alternately, introducing the first component of the water-soluble polymer into the outer circumference of the cross section of the composite yarn to completely surround the outer circumference, and then removing the soluble polymer through chemical treatment in a subsequent process. It is characterized in that it is possible to manufacture a microfiber made of only a forming polymer.

본 발명을 보다 상세히 설명하면 아래와 같다.Hereinafter, the present invention will be described in detail.

본 발명은 제1도의 확대단면도에 표시된 바와같이 횡단면의 중심으로부터 외곽부를 향하여 제1성분으로 되어 있는 8개의 분지(分枝)가 형성되어 있고, 그 사이에 섬유형성성 폴리머인 제2성분이 교호로 배열되어 있으며, 그 외주부는 제1성분으로 감싸여서 제1성분의 분지들을 서로 연결시키고 있는 것이다.In the present invention, as shown in the enlarged cross-sectional view of FIG. 1, eight branches of the first component are formed from the center of the cross section toward the outer portion, and the second component, which is a fiber-forming polymer, is alternated therebetween. The outer peripheral portion is wrapped with the first component to connect the branches of the first component to each other.

제4도에 표시된 방사구금장치를 통하여 제1도 및 제2도에 도시된 복합사의 제조과정을 설명하면 아래와 같다. 제1성분인 이용성 폴리머를 P1이라고 하고, 제2성분인 섬유형성성 폴리머를 P2라고 하면, 다수 폴리머통로(2)들 사이로 스리트(3)이 통과하고 있으므로 폴리머통로(2)를 통해 여러개로 나누어진 섬유형성성 폴리머(P2)사이로 폴리머통로(1)과 스리트(3)을 통과한 이용성 폴리머(P1)이 침투함으로써 제4도의 A－A′면에서 제2도에 표시된 바와같은 복합사가 얻어진다.Referring to the manufacturing process of the composite yarn shown in Figures 1 and 2 through the spinneret shown in Figure 4 as follows. When the usable polymer as the first component is called P 1 and the fiber-forming polymer as the second component is referred to as P 2 , since the slit 3 passes between the plurality of polymer passages 2, the polymer passage 2 is used. indicated by the infiltration by the availability polymer (P 1) through the polymer passage (1) and the switch discrete (3) between the fiber-forming polymer (P 2) it is divided into several in terms of a fourth-degree a-a 'in FIG. 2 A composite yarn as obtained is obtained.

또 이용성 폴리머(P1)는 폴리머통로(4)를 통하여 폴리머통로(6)에 도착하고, 폴리머통로(5)를 통해 내려온 섬유형성성 폴리머(P2)의 외주를 감싸기 때문에 제4도의 B－B′면에서 제1도에 도시된 바와같은 단면이 얻어지고 구금동(7)을 통하여 본 발명의 극세사용 복합사가 제조된다.In addition, the usable polymer P 1 arrives at the polymer passage 6 through the polymer passage 4 and wraps around the outer periphery of the fiber-forming polymer P 2 descending through the polymer passage 5. On the B 'side, a cross section as shown in FIG. 1 is obtained and the microfiber composite yarn of the present invention is produced through the metal cage 7.

이를 직,편하거나 부직포로 만든 후 화학적처리(NaOH 처리등)를 하여서 이용성 폴리머(P1)을 완전히 제거시킨다.It is made of woven fabric, nonwoven fabric, and then chemically treated (NaOH treatment) to completely remove the usable polymer (P 1 ).

본 발명에서 외주부와 분지부를 형성하는 이용성 폴리머의 비율은 스리트(3)과 폴리머통로(4)에 의하여 조정될 수 있다.In the present invention, the ratio of the usable polymer forming the outer peripheral portion and the branching portion can be adjusted by the slit 3 and the polymer passage 4.

통상 분지부와 외주부의 폴리머함량의 비율을 1:1로 했을 때 작업 및 화학처리가 가장 쉬웠으며 분지부가 너무 크면 상대적으로 외주부의 비율이 줄어 작업에 어려움이 있고 외주부가 크면 분지부의 비율이 줄어 화학적 처리가 어려울 뿐 아니라 분할도 잘 되지 않는다.In general, when the ratio of polymer content in the basin to the outer circumference is 1: 1, it is the easiest to work and chemically process. If the branch is too large, the proportion of the outer circumference is relatively difficult. It is not only difficult to chemically reduce, but also difficult to divide.

결국 본 발명에서 가장 좋은 단면형태는, 1) 제2성분 대(對) 제1성분의 함량비가 10:1－4:1이고, 2) 외주부 대(對) 분지부의 함량비가 4:6－6:4이내일 때이다.After all, the best cross-sectional shape of the present invention is 1) the content ratio of the second component to the first component is 10: 1-4: 1, and 2) the content ratio of the outer peripheral portion to the branch portion is 4: 6- It is within 6: 4.

본 발명에서 이용성 폴리머로는 이용성 폴리에스터가 사용되며, 섬유형성성 폴리머로는 일반 폴리에스터 또는 폴리아미드가 사용되었으며 공지의 방법으로 방사, 연신하였다. 방사속도는 700－1,200m/min, 연신비율은 3.0－4.0배로 하였다.In the present invention, a water-soluble polyester is used as the usable polymer, and a general polyester or polyamide is used as the fiber-forming polymer, and it is spun and stretched by a known method. The spinning speed was 700-1,200 m / min, and the draw ratio was 3.0-4.0 times.

본 발명의 극세사용 복합사는 직,편이 용이할 뿐만아니라 부직포로도 성공적으로 제조될 수 있기 때문에, 부드러운 촉감을 가지는 인공피혁등의 소재로 사용할 수 있으며, 또 이용성 폴리머가 차지하고 있던 약15%정도의 공간으로 폴리우레탄, 또는 P.V.C를 코팅공정에서 침투시킬 수 있으므로 탄력성이 풍부한 인공피혁을 만들 수 있다. 또한 본 발명의 극세사용 복합사는 염색할 때 2종의 폴리머가 공존함에 따르는 견뢰도 저하등의 문제도 해결할 수 있었다.The microfiber composite yarn of the present invention is not only easy to weave and knit, but also can be successfully manufactured as a nonwoven fabric, so that it can be used as a material such as artificial leather having a soft touch, and about 15% of the usable polymer occupies. Polyurethane or PVC can be infiltrated into the space during the coating process, making it possible to make artificial leather rich in elasticity. In addition, the microfiber composite yarn of the present invention was able to solve problems such as a decrease in fastness due to the coexistence of two polymers when dyed.
