Abstract
The invention belongs to the technical field of deep processing in tanning production in the leather industry and particularly relates to a production method of semi-vegetable tanning goat clothing leather. Goat wet blue leather which is treated through a conventional technology in the prior art and is shaved is used as a raw material, is sequentially subjected to weighing, backwater treatment, degreasing, water washing, retanning, second-time water washing, neutralization, third-time water washing, filling and stuffing, top dyeing, fourth-time water washing and leaving to stand, and then is subjected to finishing through the conventional technology. According to the method, dyeing and retanning are conducted simultaneously, and chromium-free retanning is adopted in the retanning procedure; the retanning and filling effects are good when a vegetable tanning agent TA and a synthetic tanning agent F are combined to be applied to the wet blue leather, and production of hexavalent chromium can be prevented; the fullness and the softness of the leather are obviously improved, so that the leather is more evenly dyed, and dyeing defects and aberration do not appear easily; the finished leather product is free of coatings, operation procedures are reduced, a large quantity of chemical material pollution is reduced, and the more environment-friendly effect is realized.
Description
Technical field
The invention belongs to the deep process technology field of leather industry tanning production, particularly relate to a kind of goat half vegetable tanning clothing
The manufacture method of leather.
Background technology
Along with the development of leather and fur internationalizationof of market, people are more and more higher to the consumption demand of leatherware, and consumer is to skin
The presentation quality of leather product is further favored and pays close attention to, as frivolous soft, silk-like handle by force, the leather products of high intensity liked by consumer deeply
Like.Owing to leatherware is far superior to common spinning at the aspect such as warming, wear-resisting, hot strength, tensile strength, tearing toughness
Woven garment product, again because leatherware occupies the forward position of fashionable dress trend the most always, society entered in development, epoch
Step, along with improving constantly of people's living standard, consumer not only focuses on outward appearance matter for leading the leather wear of fashionable dress trend
Amount, the most more focuses on environmental protection performance.
Chrome tanning leather is occupied an leading position in leather products, and owing to pollution of chromium is serious, therefore conventional chrome tanning is restricted,
Few chromium or chrome-free tanning are increasingly subject to those skilled in the art concern and attention, Given this because of, chrome-free tanning is made mountain by my company
Sheep half vegetable tanning clothing leather is defined as the direction and goal developed.
Summary of the invention
It is an object of the invention to provide the manufacture method of a kind of goat half vegetable tanning clothing leather；The goat clothes that the method makes
Dress leather belongs to half vegetable tanning, and through Final finishing without covering with paint, lacquer, colour wash, etc., finished leather color is shallow and good luster, clean environment firendly, and finished product hide is light, thin, soft, with
Body sense is strong, good permeability, it is adaptable to make fashionable dress trend clothing, and tensile strength and tearing strength all can reach industry standard and want
Ask.
The purpose of the present invention is achieved through the following technical solutions: the manufacture method of a kind of goat half vegetable tanning clothing leather；It is special
Levy be with prior art common process process shaving after goat wet blue as raw material, be weighed successively, backwater, defat,
Washing, retanning, second time washing, neutralize, third time washing, fill stuffing, top dye, the 4th time washing with stand, then according to
Common process carries out Final finishing；Concrete grammar is as described below:
