Abstract

The invention relates to a tanning and processing method of crocodile belly skin. In the existing crocodile leather tanning technology, there are problems such as difficulty in removing fat, difficulty in softening the skin plate and bone armor, difficulty in removing scales, poor bleaching and fading effect, flat and thin hollow loose leather, and improper hanging and drying methods. The present invention adopts water immersion→fleshing→oil scraping film→degreasing, preliming→oil scraping film→aldehyde pretanning→oil scraping film→liming→oil scraping film→scaling→deliming→oil scraping film→combined bleaching→softening→oil scraping film→ Combining the processes of bleaching→degreasing→softening oracle bones, bleaching→pickling, softening→tanning→shaving→degreasing→neutralization→retanning→fatliquoring→grinding→dry cleaning→dyeing→hanging to dry→finishing, the Nile crocodile The processing technology of abdominal raw leather, crocodile leather is soft, plump and elastic, and maintains a complete crocodile leather pattern. It can not only be processed into dark leather, but also light-colored leather and white leather. The finished leather can be used to process and make luggage leather , shoe leather, belt strap leather, etc., have a high market value.
