皮革を提供できるようにしたものである。In the present invention, the branch extending from the center of the cross section toward the outer peripheral edge and the small interior provided at the center are made of polyester as a first fiber-forming substance, and the branch parts adjacent to each other are In the splittable composite fiber in which the fan-shaped portion is made of polyamide as a second fiber-forming substance, the boundary between the branch portion and the fan-shaped portion is formed by a curved surface, and the total area of the fan-shaped portion is defined as the cross section. Within a range of 60 to 80% of the area, furthermore, the ratio of the diameter of the small interior to the diameter of the cross section is in the range of 1/10 to 115, and the maximum width of the branch part,
The ratio of the width of this branch at the outer peripheral edge is 4/3 to 2.
By keeping it within this range, we can improve spinnability and fiber drawing workability, improve the degree of separation and the difference in degree of separation, and provide high-density knitted fabrics or artificial leather with good dyeability and high quality. It has been made possible.

ば使用される。When producing high-density knitted fabrics or artificial leather using divisible composite fibers, for example, Japanese Patent Publication No. 53-38764, Japanese Patent Publication No. 58-5311, and Japanese Patent Application Laid-Open No. 51-60769
As disclosed in the publication, a composite fiber having a cross section as shown in FIGS. 2A to 2D, that is, a first fiber-forming substance (hatched area in the figure) and a second fiber-forming substance (white area in the figure) ) are often used.

成物質間の境界がすべて平面から成っている。このため
後述するように（第１表参照）、これらの複合繊維は比
較的に分離度が低く、また分離度差が極めて大である。In the case of these splittable conjugate fibers, except for the conjugate fiber having the cross section shown in FIG. 2B, the boundaries between the two fiber-forming substances are all planes. Therefore, as will be described later (see Table 1), these composite fibers have a relatively low degree of separation, and the difference in degree of separation is extremely large.

た後に測定する。On the other hand, in the case of the conjugate fiber having the cross section shown in FIG. 2B, the degree of separation is higher than that of the conjugate fiber having a similar cross section shown in FIG. 2C, and the difference in degree of separation is also small. However, the degree of improvement is small, and on the contrary, the problem arises that the drawing workability is lowered due to the complicated cross section. Note that the "separation degree" and "separation degree difference" are values expressed by the following formulas, respectively, and are measured after heating using a spindle type heating machine.

天然皮革に極めて似たものを作ることができない。Difference in degree of separation = (Maximum degree of separation - Minimum degree of separation) (χ) (Problem to be solved by the invention) By the way, if a separable composite fiber like the one mentioned above with a low degree of separation is used, the expected high-density knitting will be achieved. Difficult to obtain textiles. Also, if you make artificial leather, you will be able to get a soft texture.
It is not possible to make something that closely resembles natural leather.

For this reason, it is not possible to obtain uniformly dyed high-density TV6 material or artificial leather.

In the separable composite fiber in which the fan-shaped portion between the branch portions adjacent to each other is made of polyamide as a second fiber-forming substance, the boundary between the branch portion and the fan-shaped portion is formed by a curved surface. At the same time, the total area of the fan-shaped portion is within the range of 60 to 80% of the cross-sectional area, and the ratio of the diameter of the small interior to the diameter of the cross-section is within the range of 1/10 to 115 (1/10 and 1/10). 115), and the ratio of the maximum width of the branch to the width of the branch at the outer peripheral edge is within the range of 4/3 to 2 (including 4/3 and 2). A separable composite fiber was constructed.
したがって、上記可分形複合繊維を物理的又は化学的に

離度差も１５％以下に収めることができる。Therefore, when the above-mentioned splittable conjugate fibers are physically or chemically treated and separated, the degree of separation is extremely high, and the difference in degree of separation can be kept within 15%.
以下本発明の実施例につき第１図を参照しながら説明す
る。Embodiments of the present invention will be described below with reference to FIG.
本発明に係る可分形複合緬維の横断面を第１図に示す、
同図でハツチングを施した部分は、横断面の中心０に位
置を占める小内部Ａ、と、上記中心０から上記横断面の
外周縁部ｐに向って延びる枝部Ａ２とから成り、第１繊
維形成物質であるポリエステルにて構成される。A cross section of the divisible composite silk fiber according to the present invention is shown in FIG.
The hatched part in the figure consists of a small interior A located at the center 0 of the cross section, and a branch A2 extending from the center 0 toward the outer peripheral edge p of the cross section. Composed of polyester, a fiber-forming substance.
また互いに隣り合う上記枝部Ａ２間の扇形部Ｂは第２繊
維形成物質であるポリアミドにて構成される。なお扇形
部Ｂの総面積は、上記横断面の面積の６０〜８０％の範
囲に保たれる。Further, the fan-shaped portions B between the adjacent branch portions A2 are made of polyamide, which is the second fiber-forming material. Note that the total area of the fan-shaped portion B is kept within a range of 60 to 80% of the area of the above-mentioned cross section.
すなわち扇形部Ｂの上記総面積が６０％を切ると、扇形
部Ｂが紡糸後の延伸時に分離を起し易く、このため延伸
作業性が低下する。また８０％を超えると、第１図に示
すごとき横断面の可分形複合繊維を得ることが困難にな
る。That is, if the total area of the fan-shaped portions B is less than 60%, the fan-shaped portions B are likely to separate during stretching after spinning, resulting in a decrease in stretching workability. If it exceeds 80%, it becomes difficult to obtain a splittable conjugate fiber having a cross section as shown in FIG.
次に上記枝部Ａ２と上記扇形部Ｂとの間の境界は曲面で
構成される。また横断面の直径をＤ、小内部Ａ１の直径
をｄとすれば、その比ｄ／Ｄは次の範囲に保持される。Next, the boundary between the branch portion A2 and the fan-shaped portion B is constituted by a curved surface. Further, assuming that the diameter of the cross section is D and the diameter of the small interior A1 is d, the ratio d/D is maintained within the following range.
１／１０＜ｄ／Ｄ＜ １１５
すなわち上記比ｄ／Ｄが１／１０を切ると、扇形部Ｂの
中心０に近い端部における幅が小になって分離度差を高
める原因となる。また１１５を超えると、扇形部Ｂが繊
維の延伸時に分離を起し易く、このため延伸作業性が低
下する。1/10<d/D<115 That is, when the ratio d/D is less than 1/10, the width at the end of the fan-shaped portion B near the center 0 becomes small, which causes an increase in the difference in degree of separation. On the other hand, if it exceeds 115, the fan-shaped portion B tends to separate during stretching of the fibers, resulting in a decrease in stretching workability.
次に前記枝部Ａ２の最大幅をｂ、上記外周縁部ｐにおけ
るこの枝部Ａ２の幅をａとすれば、その比ｂ ／ ａは
次の範囲に保持される。Next, if the maximum width of the branch portion A2 is b and the width of the branch portion A2 at the outer peripheral edge p is a, the ratio b/a is maintained within the following range.
４ ／ ３ ＜ ｂ ／ ａ ＜ ２
すなわち上記比ｂ ／ ａが２以上になると扇形部Ｂの
分離が著しく不均一となる。このため染色時に緯方向の
染色差を起し易い。また４／３以下になると、上記横断
面が第２Ａ図に示す形に近付くから、本発明の目的を達
成できなくなる。4/3<b/a<2 In other words, when the ratio b/a becomes 2 or more, the separation of the fan-shaped portions B becomes significantly non-uniform. For this reason, dyeing differences in the weft direction tend to occur during dyeing. Moreover, if it is less than 4/3, the cross section approaches the shape shown in FIG. 2A, making it impossible to achieve the object of the present invention.

A splittable composite fiber having a cross section shown in FIG. 1 was obtained at a take-up speed of 1000 m/ff1in and a drawing ratio of 3.5.
