た。<Prior Art> Conventionally, a fibrous sheet obtained by containing an elastic polymer in a fiber-entangled nonwoven fabric has been used as a substrate for producing a leather-like sheet. Suede-like fibers with a raised surface raised on one side of this substrate by buffing with a raising machine and / or buffing to give a suede-like leather, or silver with an elastic polymer coating on one side of the substrate There are many proposals for producing a toned leather-like material. Further, Japanese Patent Laid-Open No. 173379/1984 proposes a sheet having a new structure in which the surface of the substrate is made up of naps of ultrafine fibers and naps of an elastic polymer, and the surface of which has a grain pattern. Also,
It has been proposed in JP-A-53-31887 that the surface is raised to form a raised fiber surface, treated with a solvent of an elastic polymer or a swelling agent, re-solidified, and then raised again.

ヌバツク調との混在した皮革状物は得られていない。<Problems to be Solved by the Invention> The leather-like material proposed hitherto has fine creases on the surface like a silver-finished product with leather, and although it is a silver surface, naps of ultrafine fibers are apparent. It is not possible to obtain a leather-like material in which the surface is silver and the surface is fine and the fiber is napped, which means that the nap has a hand-painting effect.

はできない。That is, in the surface finishing of the conventional leather-like material, when buffing the surface of the substrate, if the degree of buffing is increased, fiber naps are formed entirely, and no silver surface remains. On the other hand, if the degree of buffing is weakened to leave the silver surface, not only the napping property is poor, but also the surface of the silver surface is rough and fine creases cannot be finished. Further, there is a problem that the surface strength of the leather-like material cannot be finished. Further, in the method in which fiber naps are formed on the surface of the substrate in advance by buffing or the like, and then a solvent or solution of an elastic polymer is applied to the surface, the root part of the fiber naps is reinforced and the napped state is improved, but it is not broken. It is not possible to form a silver surface that generates If a solvent or solution of an elastic polymer is applied to the napped surface of the fiber until a crease is formed, a silver surface layer in which the fiber is embedded in the elastic polymer is formed, and the fiber can be buffed afterwards. No nap is formed, and a surface in which silver surfaces and fiber naps are mixed cannot be formed.

A web is prepared by a wet method or a dry method, and a fiber entangled nonwoven fabric is prepared by a needle punching method and / or a fluid jet entanglement method. Then, the fiber entangled non-woven fabric is at least selected from polyurethane elastomer, acrylonitrile-butadiene copolymer, styrene-butadiene copolymer, polyacrylic acid ester or acrylic acid ester or methacrylic acid ester copolymer, silicone rubber and the like. Impregnated with a solution or dispersion of one type of elastic polymer or a polymer mainly composed of an elastic polymer in which another polymer is mixed with another polymer, coagulated by a wet method or a dry method, washed with water, and dried. And a fiber entangled nonwoven fabric containing an elastic polymer or a polymer mainly composed of an elastic polymer.
Further, in order to make the constituent fibers of the fibrous sheet into ultrafine fibers or / and its bundled fibers, after the fiber entangled nonwoven fabric before containing the polymer or the fibrous sheet containing the polymer, The island component or the core component is transformed into the ultrafine fiber and / or its bundle-like fiber by treating the mixed fiber with the solvent or the decomposing agent of the sea component or the sheath component and removing it from the fiber. In the split-type fiber, one component of the swelling agent constituting the fiber or / and a physical or mechanical treatment is used to split the component into each component, thereby converting the fiber into an ultrafine fiber or / and a bundle fiber thereof. Another method for producing an entangled non-woven fabric of ultrafine fibers is produced by spinning a synthetic polymer by a melt blow method or a flash-spinning method to obtain a web of ultrafine fibers and performing an entanglement treatment. The fineness of these ultrafine fibers is controlled to a single fineness of 0.3 dr or less by controlling the spinning method. From the stand-up appearance, texture, surface smoothness, fiber entanglement strength, etc., it is preferable that the single fineness is 0.1 dr or less. The ultrafine fiber bundle fibers preferably have a single fineness of 0.1 to 0.0003 dr.

なくなる前の段階までの伸長を加える。Further, in order to give at least 10% area shrinkage ability to the fibrous sheet, a fiber having shrinkage ability is used for the fiber itself, shrinkage is given after the surface formation, and the fiber entangled nonwoven fabric is stretched in at least one direction. Then, the entangled non-woven fabric structure is pre-strained, and the shrinkage is applied after the surface is formed.The fibrous sheet is stretched in at least one direction, and the fibrous sheet structure is pre-strained, and the surface is shrunk. From the viewpoint of quality control, a method of applying a certain amount of strain to the fibrous sheet structure and then applying shrinkage after forming the surface is preferable. In this case, an amount sufficient to cause an area shrinkage of at least 10% is extended in at least one direction and temporarily fixed. The elongation in one direction is at least 10%, and the elongation in two directions is at least 5%. If the area shrinkage is less than 10%, a good silver surface,
Particularly, fine creases are generated, and it is not possible to obtain a surface having good smoothness or embossing property. On the other hand, in the method of imparting strain to the fibrous sheet structure by stretching, the stretching rate of one side is up to about 40%, and stretching is performed up to the stage before shrinkage due to structural destruction does not occur.

Good. The surface of this fibrous sheet is coated with a solution or dispersion of at least one elastic polymer selected from polyurethane elastomer, polyacrylic acid ester, acrylic acid ester copolymer, polyester elastomer and the like. The amount of the elastic polymer applied is such an amount that the ultrafine fibers or / and the bundled fibers thereof existing on the surface are not embedded in the elastic polymer, and the surface becomes a silver surface. However, depending on the amount of polymer contained in the fiber entangled nonwoven fabric,
The amount of elastic polymer applied to the surface is different, but generally 0.5-
15 g / m 2, and preferably an amount of 1 to 10 g / m 2. If the amount of coating is small, a good silver surface will not be obtained even if the amount of shrinkage is large, while if the amount of coating is large, the napping property will deteriorate. Further, the method for applying the elastic polymer to the fibrous sheet may be any of a roll coating method, a knife coating method, a transfer method and a spray method,
A gravure roll coating method using a scored roll is preferred from the viewpoint of coating uniformity.
