Description
Technical field
The present invention relates to a kind of clothing leather processing technique, a kind of water-fastness, environment-friendly type clothing leather processing technique.
Background technology
Tanning is a step important during rawhide is changed into leather, and the quality of tannery directly influences the thing of finished leather
Physicochemical performance, has important contacting with the value of finished leather.Currently employed main tanning agent is chromic salt, chromic salt
Tanning agent has water-fastness, shelf-stable, has the advantages such as good hydrothermal stability, but the chromium resource in the whole world is limited, and chromium is made
Being a heavy metal species, with the waste liquid produced during its tanning hide, scurf etc. the most inevitably contains trivalent chromium, and these give up containing chromium
Ecological environment will necessarily be damaged by gurry, and the easiest oxidized generation Cr VI of trivalent chromium, therefore
The tanning agent developing a kind of environmental friendliness, tanning effective is present goal in research.Existing chrome-free tanning agent exist price high,
The shortcomings such as tannery is complicated.
Clothing leather requires repeatedly to wash, but at present clothing leather repeatedly washes that to easily cause feel hardening, this be by
It is washed off in micromolecular compound therein, reduces leather hand feeling.
Summary of the invention
The abnormal smells from the patient that produces for clothing leather, wash durability is poor, chrome tanning tanning defect not environmentally, present invention substance A
(sodium ethylene diamine tetracetate, 1,2-dimethyl-3-hydroxyl-4-pyridone, 2-hydroxy propane-1,2,3-sodium tricarboxylate, 2-phosphonic acids fourth

Aluminium tanningagent is fixed by iminodisuccinic acid four sodium, compensate for the laundry-resistant defect of conventional aluminum tanning agent, uses Pericarpium Citri grandis simultaneously
Glycoside, N-naphthalene-1-base-3-hydroxyl naphthalene-2-Methanamide, glycine improve the mechanical performance of clothing leather, naringin, N-naphthalene-1-
Base-3-hydroxyl naphthalene-2-Methanamide, glycine improve the leather absorption to little molecule acrylic resin, Sorbitol, manna
Oils and fats and micromolecular compound are fixed by sugar alcohol, THPC, aluminate coupling agent, improve leather water-fastness
Property.
