A kind of manufacturing method of environment-friendly twist-resistant soft upper leather

Abstract

The invention discloses a production method of an environment-friendly tortuous-resistant soft leather, which comprises a material preparation process, a moisture rehydration process, a neutralization process, a dyeing process, a retanning process, a fatliquoring process and a dry finishing process, and the fatliquoring process includes A pre-fatliquoring process and a main fatliquoring process, and the pre-fatliquoring process, the retanning process and the main fatliquoring process are carried out in sequence, and in the retanning process, acidic phenolic tanning agents and hydroxysulfone tanning agents are used Agent, with wattle bark extract, for tanning. Using phenolic syntans and hydroxyl retanning agents to replace traditional chrome tanning agents and vegetable tanning agents, add fat and oil step by step, promote full penetration of retanning agents and uniform distribution in leather, and avoid coarse grains , Even the problem of brittleness, making the leather body smooth and moist.

Description

Technical field [0001] The present invention relates to a method of fabricating leather, in particular to a method of fabricating an environmentally friendly velocity-resistant soft section. Background technique [0002] Since the soft surface is meticulous, the granules are clear, the texture is soft, the wearing is comfortable, the sanitary performance is good, the color variety is the advantage, so it is favored by consumers, can be used to make casual shoes, slippers, sandals, fashion Shoes, etc., play a good decoration and embellishment in the fashion trend. However, there are many problems with poor water resistance in the market, poor scream resistance, crisp resistance, crisp, and large grains, so seriously restrict the application of soft-faced leather in high-grade shoe leather. [0003] With the advocacy of green consumption, vegetable tanning leather, semi-planting is highly respected, but there is a problem of hindering, no oil, absorbed weakness, can not meet consum...

AI Technical Summary

Problems solved by technology

However, most of the soft top leathers on the market have problems such as poor water resistance, poor flex resistance, hard and brittle coating materials, and coarse grains, which seriously restrict the application of soft top leathers in high-grade shoe upper leathers.

[0003] With the advocacy of the concept of green consumption, vegetable tanned leather and semi-vegetable tanned leather are highly praised by people. However, there are problems such as stiff leather, no greasy feeling, and easy softening after water absorption, which cannot satisfy consumers' requirements for shoe upper leather comfort, Requirements for softness, waxy feeling and water resistance
