Embodiment 1

[0025] Embodiment one: a kind of preparation technology of imitation cowhide microfiber shoe leather comprises the following steps:

[0026] (1) Preparation of ultrafine denier sea-island fibers: Nylon is used as the island component, low-density polyethylene is used as the sea component, nylon and low-density polyethylene are mixed and stirred evenly at a mass ratio of 50:50, and melted in a single-screw spinning machine Formed by extrusion to obtain superfine denier sea-island fibers;

[0027] (2) Preparation of non-woven fabric: The ultra-fine denier sea-island fiber obtained in step (1) is opened and carded into a web, and then punctured on a needle punching machine to obtain a non-woven fabric with a needle punching density of 1800 punches / cm 2 , the needle depth is 5mm; the needle type used in the acupuncture machine is R222 type needle, and the R222 type needle is a cone-shaped needle with three ribs, each of which has 2 barbs;

[0028] (3) Non-woven fabric heat shrink...

Abstract

The invention relates to a preparation technology for abortive-calfskin-imitated microfiber shoe leather. The preparation technology is characterized by comprising following steps: (1), preparing super-fine-denier sea island fibers; (2), preparing non-woven fabric; (3), performing thermal contraction setting on the non-woven fabric; (4), passing the non-woven fabric through a bottom resin impregnation liquid firstly, then coating the surface of the non-woven fabric with surface resin, passing the non-woven fabric through a dimethylformamide solidification liquids with the mass concentration of 40%-50%, 30%-40% and 20%-30% sequentially for solidification foaming, and performing washing finally; (5), reducing toluene; (6), performing oil application, tanning and leather grinding; (7), adopting a dry method for veneer transfer with release paper; (8), processing leather surface: adopting a 200-mesh anilox roller for polishing treatment or skin-touch treatment and performing drying; (9), performing boarding. The abortive-calfskin-imitated microfiber shoe leather is prepared from the microfibers, the technology is concise, and the abortive calfskin imitation effect of the prepared shoe leather is remarkable.

Description

technical field [0001] The invention relates to a microfiber shoe leather, in particular to a preparation process of an imitation bovine leather microfiber shoe leather. Background technique [0002] Genuine leather has good waterproof and breathable properties, but due to the constraints of its output and price and the increasing demand for leather by the human body, microfibers are more and more widely used in tanning. Fetal cowhide is the skin of a calf born 1 to 30 days old. It is the best layer of cowhide. The leather is tender and smooth, with a moderate thickness, clear tread, good hand feeling, good elasticity, and strong flexibility. It is easy to wear. Makes people very comfortable. Leather products made of fetal cowhide are more expensive, and more importantly, for animal protection, the use of fetal cowhide is unacceptable. How to use microfiber to make imitation calf leather to achieve the effect of fetal calf leather is a problem that manufacturers have been ...
