Description
Technical field
The invention belongs to garment material processing technique field, in particular it relates to a kind of water-fastness ox-hide clothing leather processing work
Skill.
Background technology
Ox-hide leather slightly has not as dress ornament material in people's daily life, the processing technology of ox-hide leather because of the difference of material
Together, the made rapid progress more because of society's great development, the processing of ox-hide leather has obtained long-range development, and the innovation of ox leather processing causes
The quality of ox-hide leather is improved so that ox leather products are increasingly subject to the pro-gaze of consumer.
Tanning is that rawhide is changed into an important step during leather, and the quality of tannery directly influences the thing of finished leather
Physicochemical performance, has important contact with the value of finished leather.Currently employed main tanning agent is chromic salt, chromic salt
Tanning agent has water-fastness, shelf-stable, there is good hydrothermal stability.
But it comes with some shortcomings:One is resource-constrained;Two be to cause environmental pollution, and chromium is used as a heavy metal species
The waste liquid produced during its tanning hide, scurf etc. all inevitably contains trivalent chromium, and these chromed leather wastes will necessarily be to life
State environmental pollution, and a kind of trivalent chromium easy oxidized generation Cr VI, therefore develop environment in use
The good tanning agent of friendly, tanning effect is present goal in research;Three be the shortcomings of price is high, tannery is complicated.
Clothing leather is required to multiple washing, but at present clothing leather repeatedly washing easily causes feel and is hardened, this be by
It is washed off in micromolecular compound therein, reduces leather hand feeling.
The content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of water-fastness ox-hide clothing leather processing technology,
