Embodiment approach 1

[0025] Embodiment 1, the tanning process of Tiaozipi amphoteric vegetable tanning agent consists of a preparation process, a tanning process and a finishing process;

[0026] The preparatory process is to soften the collected raw hides, restore the raw hides to the state of fresh hides, and remove the excess components between the fibers of the raw hides and plates, which include subcutaneous tissue, sarcolemma, and protein; The specific steps of the preparation process are:

[0027] Pool drum combined with soaking, put the collected raw skins into the immersion pool, fully return the raw skins to the natural state of fresh skins, soften the raw skins, remove blood stains, dirt and preservatives on the raw skins, Remove part of the fibrous interstitium and weaken the subcutaneous tissue; immerse in water in grooves, drums and pools, and follow the principle of countercurrent when immersing in water; remove salt, dirt and blood on the surface of raw hides by washing with water,...

Embodiment approach 2

[0044] Embodiment 2, the specific steps of the preparation process are:

[0045] Pool drum combined with soaking, put the collected raw skins into the immersion pool, fully return the raw skins to the natural state of fresh skins, soften the raw skins, remove blood stains, dirt and preservatives on the raw skins, Remove part of the fibrous interstitium and weaken the subcutaneous tissue; immerse in water in grooves, drums and pools, and follow the principle of countercurrent when immersing in water; remove salt, dirt and blood on the surface of raw hides by washing with water, and control the temperature to make the raw materials The salt in the skin is dissolved, and some additives, such as surfactants, fungicides, etc., can be added at the same time, so that the immersion of the salted skin can achieve better results; when immersing, it is carried out according to the principle of countercurrent, pool and pool, pool and drum, Drum and drum tanning solution concentration incr...

Abstract

A kid lamb skin tanning process using an amphoteric vegetable tanning agent is composed of a preparatory step, a tanning step, and a finishing step; the preparatory step comprises softening collected kid lamb raw skins to restore the raw skins to the conditions of fresh skins, and removing redundant components between skin plate fibers of the raw skins; the tanning step comprises primary tanning and main tanning; in the tanning step, filling primary tanning of the skins is completed mainly by means of the characteristics of macromolecules, high filling ability, good extensibility, and stable stereostructure of the vegetable tanning agent; further, in the tanning step, tanning is carried out by using a low-astringency low-concentration vegetable tanning liquor, and after the collagenous fibers of the naked skins are primarily immobilized, permeation and filling of the tanning liquor are completed gradually to guarantee that a tannin gradually permeates into the naked skins and bonds with skin collagen; and the finishing step comprises fat-liquoring, moisture regaining, staking and shaping of the skin plates as well as hair finishing. The kid lamb skins tanned by means of the kid lamb skin tanning process using the amphoteric vegetable tanning agent has the advantages of small difference between thin and thick parts of the skin plates, full plate texture, fine piles, and locks of bent hair that is natural, has rich wonderful luster and may rival Tan-sheep kid furs.

Description

Technical field: [0001] The invention relates to the technical field of animal hide tanning processing technology, in particular to a tanning process of raccoon skin with an amphoteric vegetable tanning agent. Background technique: [0002] Ningxia scorpion leather is thin, with less underlining, rich guard hair, tight fiber structure, and difficult to fill. Generally, scorpion leather tanned by traditional tanning techniques has quicksand, dry hair, hard skin, and tight fiber structure. , Filling difficult technical problems, at the same time, the product and the environment caused by the process itself are polluted, and precious resources have not been effectively developed. [0003] As people's attention to environmental protection continues to grow, vegetable tanning agents will once again become a tanning agent that is happy to be used in leather and fur making processes, and vegetable tanned leather will also regain its former status in the world's leather industry.
