供するものである。 It is well known that in the past, in the production of artificial leather, methods have been discovered to make soft artificial leather by dissolving and removing at least one component of multicomponent fibers, and excellent artificial leather products have been provided. . However, in this method, when one component is dissolved and removed using a solvent, it is passed through a nip roll for squeezing, so the multicomponent fibers present in both outer layers of the sheet are strongly compressed at the same time as one component is dissolved. As a result, the density of the fibers remaining in both outer layer portions increases significantly, and it is inevitable that a difference in fiber density will occur between the fiber density of the inner layer and the fiber density of the inner layer. This difference in fiber density between the outer layer and the inner layer results in a structure similar to that of cardboard, which causes the resulting artificial leather to have folds that look like paper, and the curves at the bends to be less beautiful. An object of the present invention is to provide a method for removing one component of multicomponent fibers that does not result in such a corrugated structure, and to provide a method for producing artificial leather with excellent creases.

The fiber sheet-like material is made by laminating the fiber sheet-like material alternately so that the layers (called "layers") are integrated, and then the fiber sheet-like material is coated with a solvent that dissolves the solvent-removed component of the fiber (B) but does not dissolve the solvent-removable component of the fiber (A). After processing to dissolve and remove only the solvent-removed component of the fiber (B) and increase the fiber density of both outer layer parts of the B layer, a fiber sheet-like product is further processed with a solvent that dissolves the solvent-removed component of the fiber (A). to dissolve and remove the solvent-removable component of the fiber (A), increase the fiber density of both outer layer portions of the layer A, and reduce the difference in fiber density between the outer layer and the inner layer of the fiber sheet.

いて本発明の効果は最も発揮できる。 That is, the present invention achieves the above-mentioned object by controlling the phenomenon in which the density of both surface layers increases when the solvent-removed component is dissolved, and thereby averaging the density distribution of the entire sheet. Specifically, first, only the solvent-removable component of at least one layer of a laminate in which multi-component fibers with different solvent-removable components are laminated alternately is removed, and then the remaining solvent-removable components of the laminate are removed to produce a laminated fiber sheet. By making the laminated fiber sheet-like material, the fiber density near the lamination interface is made equal to the fiber density of both surface layer parts, and the fiber density of both surface layers and inner layer of the laminated fiber sheet-like material is averaged, resulting in a laminated structure in which a corrugated cardboard structure does not occur. It consists of forming a fiber sheet-like product.
The fibrous sheet mentioned here is most preferably a non-woven fabric sheet, but it does not necessarily have to be composed only of non-woven fabric, and other fibrous materials such as woven or knitted fabrics can be used as one component constituting the inner and outer layers. Of course it is possible. For example, in the method of the present invention described above, the fiber layer made of multicomponent fiber (A) and the fiber layer made of multicomponent fiber (B) may be in the form of not only a nonwoven fabric but also a woven fabric or a knitted fabric,
It may also be a nonwoven fabric that includes woven or knitted fabrics. Further, as long as the object of the present invention can be achieved, any number of sheet-like materials may be stacked.
Since such a corrugated structure usually appears prominently in thick sheets, the effects of the present invention can be most exerted in nonwoven fabric sheets.

ないことは明らかである。 The multicomponent fibers (A) and (B) used in the present invention include fibers with a chrysanthemum-shaped cross section in which the solvent-removed component is radially dispersed between the remaining components, bimetallic fibers consisting of the solvent-removed component and the remaining component, Core-sheath type fibers, multiphase bimetallic fibers, multiphase bimetallic fibers with a donut-shaped cross section, polymer array fibers in which at least two component polymers are arranged during spinning, and blends in which at least two component polymers are mixed and spun. Examples include sea-island type fibers such as spun fibers. These fibers are suitable for the method of the present invention because the solvent-removed components are dissolved by solvent treatment and modified fibers consisting of the remaining components are generated. Among these multicomponent fibers, island-in-the-sea multicomponent fibers such as polymer array fibers and mixed spun fibers are particularly preferred in terms of ease of spinning. Preferred forms of the polymer array fiber include one in which a large number of ultrafine fiber-like island components continuous in the fiber axis direction are arranged and aggregated and enveloped with a sea component (solvent removal component), and one in which the island component has two These include those made of more than one species of polymer, and those in which the island component further forms a sea-island structure. A preferable form of the mixed spun fiber is one in which at least two kinds of polymeric substances are melt-mixed and spun, and island components dispersed in the form of a large number of microfibers are wrapped in a sea component (solvent-removed component). be. In any case, it is necessary that the solvent removal component of the multicomponent fiber (A) and the solvent removal component of the multicomponent fiber (B) have different solubility in the solvent. When a plurality of layers of multicomponent fibers (A) or layers of (B) are laminated, the remaining components may be of different types. It is clear that this does not impair the effects of the present invention in any way.

Examples include polyacrylonitrile, vinyl polymer, polyurethane, and the like. Among these polymeric substances, we selected those with different solvent solubility, and also took into consideration spinnability and interaction with the remaining component polymers to form multicomponent fibers (A) and multicomponent fibers (B). can be applied to each of the solvent removal components.
For example, polystyrene is soluble in toluene at room temperature, and polyethylene is soluble in hot toluene, so polyethylene is used as the solvent removal component of the multicomponent fiber (A), and polyethylene is used as the solvent removal component of the multicomponent fiber (B). When making polystyrene, the fibers are first processed using toluene at room temperature.
The laminated fiber of the present invention can be obtained by removing only the solvent-removed component of (B) with a solvent to produce a modified fiber of the remaining component of fiber (B), and then dissolving and removing the solvent-removed component of fiber (A) with hot toluene. A sheet-like product is obtained.

ため段ボール構造が防げるのである。 Furthermore, in the present invention, the fiber sheet is treated with a solvent of the solvent-removed component of the remaining multi-component fiber (A), so that the modified fibers made of the remaining components of the multi-component fiber (A) are entangled. A laminated fiber sheet of the present invention is obtained in which a fiber layer formed by entangling modified fibers from the remaining components of the multicomponent fiber (B) is integrally laminated on the layer. In this treatment, the multicomponent fiber (A) layer is subjected to the dissolution action and compression action of the solvent, so that the remaining fiber aggregates of the surface layer of the multicomponent fiber (A) layer and the (B) layer The density of the fibers consisting of the remaining components at the lamination interface in contact with the layers increases. Therefore, the overall density distribution of the laminated fiber sheet is a pattern in which the fiber density is increased in the surface layer portion and the lamination interface portion on both sides of the cross section, and the density distribution of each laminated fiber sheet is Since the fiber density is not significant, the fiber density is averaged out as a whole. This prevents a cardboard structure.
