Problems solved by technology

[0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. One of the uses of leather is to prepare leather shoes. It is breathable, moisture-absorbing, and has good hygienic performance. The highest shoes, because leather shoes are used for sports after wearing, often encounter hard objects when walking, or because of wrong walking posture, the upper of leather shoes is often damaged by friction, so leather shoes are required to have better comfort and durability. Abrasive, but the leather shoes currently on the market are easily damaged after being collided with or rubbed against hard objects during exercise

Embodiment 1

[0017] A method for preparing wear-resistant leather for shoemaking, comprising the following steps:

[0018] (1) Tanning: Put the pickled leather in the chrome tanning agent, soak it at 46°C for 30 minutes to promote the penetration of the chrome tanning agent into the leather, cool down to 7°C, and run it in a drum for 18 hours to promote the chrome tanning agent to penetrate into the leather. Combine closely with the collagen of the leather, then increase the temperature to 37°C, run for 13 hours, accelerate the aging of the leather, shorten the tanning time, improve the strength and softness of the leather, avoid the traditional low-temperature tanning that reduces the softness of the leather, and obtain tanned leather;

[0019] (2) Baking: Wash the tanned leather in clean water, bake until the water content is 42-46%, and the temperature is 53-55°C, so that the protein fibers of the leather will quickly dehydrate and harden, forming a protective layer on the surface. Impr...

Embodiment 2

[0024] A method for preparing wear-resistant leather for shoemaking, comprising the following steps:

[0025] (1) Tanning: Put the pickled leather in the chrome tanning agent, soak it at 48°C for 35 minutes to promote the chrome tanning agent to penetrate into the leather, cool down to 8°C, and run it in the drum for 19 hours to promote the chrome tanning agent to penetrate into the leather. Combine closely with the collagen of the leather, then increase the temperature to 38°C and run for 14 hours to speed up the aging of the leather, shorten the tanning time, improve the strength and softness of the leather, avoid the reduction of the softness of the leather by traditional low-temperature tanning, and obtain tanned leather;

[0026] (2) Baking: Wash the tanned leather in clean water, bake until the water content is 42~46%, and the temperature is 54°C, so that the protein fibers of the leather can be rapidly dehydrated and hardened, forming a protective layer on the surface, a...

Embodiment 3

[0031] A method for preparing wear-resistant leather for shoemaking, comprising the following steps:

[0032] (1) Tanning: Put the pickled leather in the chrome tanning agent, soak it at 50°C for 40 minutes to promote the penetration of the chrome tanning agent into the leather, cool down to 9°C, and run it in a drum for 20 hours to promote the chrome tanning agent to penetrate into the leather. Combine closely with the collagen of the leather, then increase the temperature to 39°C and run for 15 hours to speed up the aging of the leather, shorten the tanning time, improve the strength and softness of the leather, avoid the reduction of the softness of the leather by traditional low-temperature tanning, and obtain tanned leather;

[0033] (2) Baking: Wash the tanned leather in clean water, bake until the water content is 42~46%, and the temperature is 55°C, so that the protein fibers of the leather can be dehydrated and hardened quickly, forming a protective layer on the surfac...

Abstract

The invention mainly relates to the technical field of leather processing, and discloses a preparation method of wear-resisting leather for shoe making. The preparation method comprises the steps of tanning, baking, strengthening and drying. The method is simple, operation is facilitated, flexibility and wear resistance of the leather are increased, deformation is not prone to happening, and durability of leather shoes is improved. A pickled leather body is put in a chrome tanning agent, high-temperature short-time soaking is firstly carried out, and the chrome tanning agent is promoted to permeate into the leather; then low-temperature long-time soaking is carried out, and the chrome tanning agent and collagen of the leather are promoted to be closely combined; then the temperature is improved for soaking, leather curing is accelerated, the tanning time is shortened, the strength and softness of the leather are improved, and the situation that the softness of the leather is reduced due to traditional low-temperature tanning is avoided; and baking is carried out after tanning, azelon of the leather loses water and is hardened fast, a protection layer is formed on the surface, and wear resistance of the leather is improved.

Description

technical field [0001] The invention mainly relates to the technical field of leather processing, in particular to a preparation method of wear-resistant leather for shoemaking. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. One of the uses of leather is to prepare leather shoes. It is breathable, moisture-absorbing, and has good hygienic performance. The highest shoes, because leather shoes are used for sports after wearing, often encounter hard objects when walking, or because of wrong walking posture, the upper of leather shoes is often damaged by friction, so leather shoes are required to have better comfort and durability. Abrasion, but the leather shoes currently on the market are very easy to break after colliding or rubbing against hard objects during exercise. Contents of the invention [0003] In order to make up for the defects of the prior art, ...
