Description
Technical field
The present invention relates to a kind of environment-friendly type clothing leather processing technique, the lowest bloom, the environment-friendly type Corii Caprae seu Ovis of low abnormal smells from the patient
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
Be washed off in micromolecular compound therein, reduce leather hand feeling, simultaneously the least molecule of clothing leather and other
Oils and fats discharges or migrates out Organic substance release, have impact on leather smells and use.
Summary of the invention
The abnormal smells from the patient that produces for clothing leather, wash durability is poor, chrome tanning tanning not environmentally, produce bloom defect,
Invention uses naringin, N-naphthalene-1-base-3-hydroxyl naphthalene-2-Methanamide, glycine to improve the mechanical performance of clothing leather,
Sorbitol, 2-bromo-2-nitro-1,3-propanol, pyridoxol, D-panthenol, oleamide, polyacrylamide, 2,3-dihydroxy fourth two
Acid improves the leather absorption to little molecule acrylic resin, Sorbitol, mannitol, THPC, Aluminate
Oils and fats and micromolecular compound are fixed by coupling agent, 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride, polymine, Alumen,
Titanium dioxide, Pulvis Talci can avoid bloom, and absorb fine molecular compound.
A kind of environment-friendly type sheepskin garment leather processing technique, it is characterised in that:

After washing, the clothing leather of the present invention is not reduced to less than 85 DEG C, and the receipts of the conventional sheepskin garment leather without chrome tanning
Contracting temperature is far below 85 DEG C.
Cross direction tensile strength/MPa before and after table 2 washing
After washing, the clothing leather tensile strength of the present invention reduces little, and the conventional sheepskin garment leather without chrome tanning is anti-
Zhang Qiangdu is greatly reduced.
Looking for 3 process hides engineers to hear the abnormal smells from the patient of the present invention, experiment finds, the abnormal smells from the patient of the present invention substantially to produce less than routine
Sheepskin garment leather, the most respectively at 10 days, 50 days, 180 days observe leather surface situation, find the present invention clothing leather do not have
Bloom produces, and the clothing leather produced greatly has a small amount of bloom to produce.
Table 3 haze value situation
Haze value indirect reaction micromolecular compound therein amount, finds from experiment, the haze value of the present invention is significantly less than
The conventional big clothing leather produced.
Above embodiments of the present invention are explained in detail, but the invention is not restricted to above-mentioned embodiment, in institute
State in the ken that technical field those of ordinary skill is possessed, it is also possible to make on the premise of without departing from present inventive concept
Various amendments.These are all the most creative amendments, as long as all by Patent Law in scope of the presently claimed invention
Protection.
