Abstract

The invention relates to a fetal calf leather processing technology and fetal calf wet blue leather and fetal calf leather, which sequentially comprises the following processing steps: the processing steps of fetal calf wet blue leather are as follows: the calf calf leather is sequentially soaked in water, drenched in alkali and plucked, and liming , deliming, softening and pickling tanning to obtain fetal bovine wet blue leather; the processing steps of fetal bovine leather are as follows: the above-mentioned fetal bovine wet blue leather is sequentially degreased, retanned, neutralized, filled, fatliquored, dyed and finished. processed to obtain fetal calf leather; successfully processed fetal calf leather with fine-grained, uniform color, natural and elastic texture, and up-to-standard mechanical properties by processing fetal calf raw material leather; also disclosed fetal calf nubuck leather and its processing technology, successfully The surface is fine and silky, soft and has a warm and velvety surface feel after processing.

Description

Technical field [0001] The present invention relates to the technical field of leather product processing, and specifically, the processing technology and fetal cattle blue wet leather and fetal cattle leather, fetal cattle are rigid and craftsmanship. Background technique [0002] Leather is a physique such as hair removal and tanning, and has a variability that is not easy to rot. There is a special granular layer with natural granulos and gloss, which can be processed into a shoe, clothing, furniture decoration. Layers, auto interiors, etc., their feel is comfortable, and they are deeply loved by users. [0003] Leather processed leather source mainly has goatskin, sheep skin, fetal leather, calf skin, middle leather, big leather, buffalo, pig skin, horse skin, etc., different fuses, performance, processing details of processing processes Are not the same. Among them, the fetal leather finger did not start grazing breast, the opening 5-10sf, the pores were delicate, even can't...
