Embodiment 1

[0043] 1. Select the polyester sea-island superfine fiber whose fineness is 82.5-333dtex (preferably the fineness of superfine fiber monofilament is below 0.55dtex) as the suede warp (1), and use the fineness of 82.5-222dtex high chemical fiber as the ground Warp (2), ground latitude (3), suede warp (1) adopts V font (as figure 2 or image 3 shown) or W font (such as Figure 4 Shown) consolidation, through the double-layer warp pile weaving technology, weaving double-layer fleece gray cloth on the pile loom (such as Figure 5 As shown), the velvet warp thread connecting the two layers of ground fabric is cut off by the cashmere cutting knife, so that the double-layer gray fabric is divided into two pieces with ground warp (2), ground weft (3) and V or W shape respectively. Cashmere warp (1), called wool surface, is a three-dimensional structure of single-layer cashmere gray cloth (such as Figure 6 shown);

Abstract

The invention discloses a superfine fiber artificial leather and a manufacturing method thereof. In the manufacturing method, with a double-layer warp emerizing weaving process, high-strength filaments (or other filaments) are used as ground warps and ground wefts, terylene island superfine fiber or other superfine fibers are used as pile warps, the pile warps are fixedly connected in a V shape or W shape and woven into three-dimensional pile greige cloth, and then the superfine fiber artificial leather is formed by polyurethane resin padding, alkali treatment, emerizing, dying and finishing.The superfine fiber artificial leather has the advantages of fine and smooth surface villus, higher density, strong leather texture, good wear resistance, stable size, moisture absorption and ventilation, good color firmness and excellent mechanical property and can be used as clothing leather, upper leather, automobile interior material, leather for furniture and the like.

Description

technical field [0001] The invention relates to a superfine fiber artificial leather and its manufacturing method, more precisely, it is a kind of superfine polyester as the main raw material, using a special three-dimensional weaving process, combined with a special polymer elastic body, using a wet method Suede leather made by leather technology and a manufacturing method thereof belong to the field of textile and leather technology. Background technique [0002] At present, most of the microfiber artificial leathers produced at home and abroad are made of sea-island microfibers, which are opened, carded, formed into a net, and then repeatedly consolidated by a needle (or spunlace) machine to become a gray cloth, and then processed Polyurethane padding, solidification, lye (or solvent) dissolves (or extracts) the part of the sea, and finally sands, dyes, and finishes to obtain the finished product. [0003] The island microfiber can be divided into indefinite island type ...
