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

A kind of superfine fiber artificial leather and manufacture method thereof

Technical field

The present invention relates to a kind of superfine fiber artificial leather and manufacture method thereof, or rather, a kind of take super fine polyester as main raw material, use special three-dimensional woven technique, in conjunction with special macromolecular elastomer, suede and the manufacture method thereof using the wet method leather-making technology and make belong to weaving and leather technology field.

Background technology

At present, the superfine fibre of producing is both at home and abroad manually removed from office, take island superfine fiber as raw material mostly, by shredding, combing, one-tenth net, repeatedly fixed and become grey cloth by acupuncture (or water thorn) machine again, then through part that polyurethane pads, solidifies, alkali lye (or solvent) dissolves (or extraction) sea, finally by sanding, dyeing, arrangement, get product.

And island superfine fiber is different according to the production technology that adopts, can be divided into not two kinds of figured type island superfine fibers (indefinite island is super fine) and figured islands-in-sea superfine fibre (deciding the island super fine).Island in the super fibre in indefinite island is uncontrollable, is discrete on the longitudinal axis, forms thickness, the irregular superfine fibre of length after processing by solvent; Decide the island super fine be continuous on the longitudinal axis, be that the island number is fixed, fiber, the uniform superfine fibre that length is consistent.The quantity of deciding island in the super fibre in island generally has several specifications such as 16 islands, 24 islands, 37 islands, 64 islands, and commonly used is 37 islands.

For the artificial leather of the nylon ultrafine fiber on indefinite island, its super fibre in indefinite island normally polyamide and polyethylene or other ease of solubility polymer blend according to a certain percentage reels off raw silk from cocoons and forms, after making artificial leather base cloth, open fibre with the toluene polyethylene dissolving again, then carry out post processing, the product that this technique is made, thin reached at the 0.0001dtex of its fibre single thread fiber number, more than thick reached at 0.1dtex, the discreteness of fiber number is large, affects for rear processing and product quality; And in process of production, the volatilization of toxic solvent toluene is very large to operating personnel's health and ambient influnence.The characteristic of adding nylon fiber itself determines, exist product lack of homogeneity, COLOR FASTNESS low, ABRASION RESISTANCE is bad, fine hair is fine and close not, the not high defective of density, its Application Areas has been subject to certain restriction.

Make the base cloth of artificial leather with non-weaving cloth, fiber is by acupuncture (or water thorn), make it obvolvent entangled to each other together, and this entanglement has its unstability, (producer that also has adds one deck woven fabric in the middle of non-weaving cloth, to increase the stability of product).Though through the polyurethane resin embedding, fiber still comes off from product than being easier to, namely it wears no resistance, and the formed three-dimensional fiber of this technique is insufficient, and surperficial fine hair is sparse, causes the product feel coarse, can not satisfy the instructions for use in some field.

Summary of the invention

Insufficient in order to overcome in prior art the three-dimensional fiber of artificial leather, surperficial fine hair is sparse, causes the product feel coarse, can not satisfy the defective of the instructions for use in some field.
