。[Prior Art] Traditionally, woven and knitted fabrics and non-woven fabrics using core-sheath type, side-by-side type, seabird type, or multilayer laminated composite fibers have been created, and the composite fibers have been prepared before applying an elastic polymer. A method for producing artificial leather is known in which ultrafine fibers constituting the fibers are thinned and then treated with a highly elastic polymer. This type of artificial leather does not meet the required mechanical strength and bending durability, or the fiber base material used for artificial leather has a low apparent density. When folded, wrinkles occur and crystallization occurs, and the texture is hard and lacks a soft feel. In order to improve this drawback, even if the fiber base material is subjected to pressure treatment to increase the apparent density of the fiber base material, only the surface layer of this type of fiber base material has high density, and when folded, There was a problem that the wrinkles got worse. Furthermore, even if the surface of the fiber base material was subjected to a napping treatment, it was not possible to obtain a material superior to natural nubuck or suede because the napping density was low. Furthermore, attempts have been made to use high shrinkage fibers for the fiber base material. In other words, a raised sheet made of ultrafine fibers using high-shrinkage fibers as the weft of the fabric serving as the fiber base material or the yarn supplied to the back reed of warp knitting is heat-treated to increase its apparent density. However, by increasing the nap density, a fiber base material with a soft surface touch can be obtained.
しかし、この場合は高収縮性繊維を使用しているため裏
面は一般の織編物と同様にザラザラしたタッチとなる。However, in this case, since highly shrinkable fibers are used, the back side has a rough touch like a general woven or knitted fabric.

り、十分なものが得られない。In addition, when manufactured by mixing similar high-shrinkage fibers with non-woven fabric, the apparent density can be increased and a soft texture that does not cause wrinkles when folded can be obtained, but both the front and back sides have high shrinkage. It is not possible to obtain a sufficient soft touch due to the appearance of sexual fibers. Furthermore, imparting high shrinkage to ultrafine fibers requires the use of molymer with different physical properties, which results in poor spinning properties, making it difficult to obtain sufficient fibers.

収縮性ポエステルの割合が低下し表面積の収縮が十分行
えないことがあり好ましくない。The composite fiber used in the present invention has at least one polymer component made of polyester, and can be used in any of the following composite forms: core-sheath type, side-by-side type, island-in-the-sea type, and multilayer lamination type. Specifically, a core-sheath type in which two or more types of polymers are arranged concentrically, a side-by-side type in which two or more types of polymers are arranged in parallel positions,
Furthermore, in the sea-island type, a polymer component with a low dissolution rate (hydrolysis rate) is dispersed and arranged in eight or more island components in the cross section of the fiber, and a sea component polymer is arranged between the island components. At the same time, it is necessary that each component is continuously arranged in the fiber axis direction, and that the polymer of the sea component is more easily soluble than the polymer of the island component. Further, in a multilayer laminated composite fiber, components made of two or more types of polymers having different solubility are alternately arranged adjacent to each other in a cross section. The conjugate fiber has a denier of the single fiber component after splitting or elution of 1. It is necessary that the fibers contain ultrafine fibers with a diameter of less than Ode, preferably less than 0.5 de, and the blending ratio of these composite fibers satisfies the range of 40 to 90% by weight. If the blend ratio of the composite fiber is less than 40% by weight, high density can be obtained by heat shrinkage treatment, but not only the polyester that is one component of the composite fiber but also the high shrinkage polyester mixed with the composite fiber will be eluted by alkali treatment. Therefore, the specific gravity of the polyester decreases, which is not preferable. On the other hand, if the blending ratio of the conjugate fiber exceeds 90% by weight, the proportion of highly shrinkable polyester may decrease and the surface area may not be sufficiently shrunk, which is not preferable.
該高収縮性ポリエステル繊維は、洪水収縮率が２０％以

るには時間が掛かるという欠点がある。The highly shrinkable polyester fibers having a flood shrinkage rate of 20% or more are effectively used; if the shrinkage rate is less than 20%, the areal shrinkage will be insufficient. Furthermore, this high shrinkage polyester fiber is preferably copolymerized with 5-sodium sulfoisophthalate component at a ratio of 1.5 mol% or more; if it is less than 1.5 mol%, it takes time to dissolve with an alkaline solution. There is a drawback.

革ではしわが発生し易く、ソフトな風合も得られない。In the present invention, composite fibers and high shrinkage polyester fibers are used to create the fiber base material. It is also possible to use a blend of both fibers, to mix and knit the respective fibers when creating a woven or knitted fabric, or to make a non-woven fabric by using a card or the like. Next, the fiber base material obtained in this way was subjected to shrinkage treatment to give an area shrinkage rate of 15%.
It is preferable to shrink the material more than that. The area shrinkage rate is 15
If it is less than %, high density of the fiber base material cannot be obtained, and density uniformity is also insufficient, and artificial leather using the fiber base material is prone to wrinkles and cannot obtain a soft texture. do not have.
また、かかる人工皮革では寸法安定性が低く、特に薄物
の場合には取扱性が低下するので好ましくない。In addition, such artificial leathers have low dimensional stability, and especially in the case of thin materials, handling properties are lowered, which is not preferable.

密度のシートであるため寸法安定性も得られる。Next, an elastic polymer is applied to the fiber base material thus obtained, but it is important to perform an alkaline solution treatment before or after applying the elastic polymer. Through this treatment, the polyester component is eluted, the composite fiber is made ultra-fine, and the high shrinkage polyester is also eluted, so that the fiber base material is composed only of the ultra-fine fibers. By buffing the surface of a sheet-like material obtained by adding a polymer elastic material to a fiber base material made of ultra-fine fibers in this way, a surface touch similar to natural nubuck-like suede with a high nap density can be obtained. In addition, since this is a high-density sheet made of ultrafine fibers, it also provides dimensional stability.
