シート製品の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for producing dyed leather-like sheet products. More specifically, the present invention relates to a method for manufacturing a leather-like sheet product in which the pieces cut into a desired product shape or the final product shape are dyed to create a color change within the pieces.

Conventionally, fibrous sheets, especially leather-like sheets, have been dyed in long lengths using a Jitzger dyeing machine, a wince dyeing machine, a liquid fabric reflux dyeing machine, or the like. In this case, the dyed sheet material has a uniform hue when viewed in cut pieces, and depending on the product orientation, it is not possible to design a product that emphasizes the characteristics resulting from the color tone. Furthermore, the cut edges of the cut sheet generally appear pale or whitish, and it is not desirable in terms of appearance to commercialize the product with the cut edges intact. For this purpose, methods of re-coloring the cut edges or pre-coloring the constituent fibers and elastic polymers during the production of leather-like sheets are described in Japanese Patent Publication No. 55-504 and Japanese Patent Publication No. 59-12785, etc. There is. However, these methods only increase the complexity of the steps and make it impossible to match the hue of the surface with the hue of the cut end. Furthermore, this results in higher costs.

の表面色調の単調さ、切り口の色むらについては
大幅に改善されたものではない。 Furthermore, in the processing of long objects, the entire process cannot be carried out without tension, and as a result, the texture of the leather-like sheet after dyeing becomes stiff. Therefore, in order to prevent the texture from becoming stiff during dyeing, a method for dyeing leather has been proposed in Japanese Patent Publication No. 8232/1983. Since this method uses leather processing equipment to process short pieces, the texture is improved compared to long pieces, but the monotony of the surface color and the cut There was no significant improvement in color unevenness.

The present invention reduces the monotony of the color tone of the surface, and the cut end of the cut piece is colored in the same hue as the surface, and when it is made into products such as clothing parts, bags, belts, shoes, gloves, etc. Another object of the present invention is to produce a leather-like sheet with small dimensional changes and good texture and appearance. Furthermore, we manufacture products in small batches and in multiple colors.

状も天然皮革様の細かいきれいなものであつた。 The resulting shoes are well-dyed on the perforated cross section and the cut end of the cut pieces, and the surface areas around the holes, seams, and pieces are slightly darker, and the hue and depth of color increases toward the inside. The product had a slightly changed appearance, and the product had a solid appearance, and the folds were fine and clean, similar to natural leather.

あつた。 For comparison, the same leather-like sheet was dyed with a Jitzger dyeing machine under the dyeing conditions described above, washed with water, dried with a pin tenter, and then dried with a fixed width. The resulting dyed product was slightly light in color and was dyed uniformly. This leather-like sheet was cut into small pieces for shoe hole leather, made into shoes in the same manner as above, and a similar dye solution was applied with a brush to the cut ends of the pieces, but it had a different texture, so it was further applied to the hole area. It looked dirty and spoiled its appearance. The shoes as a whole have a flimsy feel and cannot be made into something special. In addition, the texture was a little hard, and the creases were similar to that of a broken piece.

A colored finishing layer made of an easily dyeable polymer containing a brown pigment and a polyurethane elastomer and a polymer finishing layer mainly made of a polyurethane elastomer for gloss adjustment are applied to the leather, and a calf-like embossing is applied to the leather. The sheet [] was cut into small pieces for shoulder bags. On the other hand, a leather-like sheet with a suede-like surface is made by applying a napped treatment to the surface of the base material, which is made of an entangled nonwoven fabric of nylon ultrafine fiber bundles and containing a porous polymer made of an easily dyeable polymer and a polyurethane elastomer. ] is cut into small pieces to be sewn for shoulder bag accessories, and then a pattern is stamped onto the raised side of the cut piece at a temperature sufficient to partially fuse the raised side to the raised side. The pieces were made up of a mixture of the fused surface and the fused surface. These pieces were then dyed in the same dyeing tank under the following conditions.

茶色であつた。 On the other hand, the leather-like sheet [] was finished with a raised surface even after brushing after dyeing. The resulting pieces had a slightly dark golden brown on the raised side and a bright two-tone dark brown on the embossed side, but the brown color was different in hue from the surface of the leather-like sheet [ ]. It was hot.

After applying a non-porous layer of polyurethane elastomer containing a brown pigment to the surface of the coating layer of the substrate provided with the polymer coating layer, and further applying a non-porous layer of polyurethane elastomer containing easily dyeable polyurethane, Leather-like sheet obtained with cowhide-like embossing []
The product was cut into the upper leather of men's shoes, sewn, and a sole was attached to make a product, which was then dyed and soaped using the same dye composition and dye conditions as in Example 3.
After washing with water, it was dried with hot air on a wire mesh. The resulting men's shoes had a dark brown color in the sewing area, a slightly reddish brown color in the interior, and a deep color tone due to the interaction of pigments, dyes, and the dye's dyeability. It had a profound feel due to its hue.

The method of the present invention includes pieces obtained by cutting into a product shape or a semi-finished product obtained by sewing or joining the pieces,
Alternatively, by shaping the final product and dyeing it under no tension, you can dye the interior of the cut edges, stitch holes, etc. at the same time, as well as dye the surfaces around the pieces, the surfaces around the holes, and the stitches. There are subtle changes in hue and tone between the surface and other parts, and between concave and convex parts of the embossing, giving it a solid appearance and giving it a tasteful product design. It will be done.
