Production and processing technology of high-density sheared sheepskin

Abstract

The invention discloses a production and processing technology of high-density sheared sheepskin, and relates to the field of production and processing of sheared sheepskin, and the production and processing technology comprises the steps of raw skin obtaining, soaking, dehydration, primary fleshing, degreasing and dehydration, re-soaking, secondary fleshing, (softening, pickling and tanning), high-temperature shrinkage, dry cleaning, rewetting, high-temperature degreasing, primary ironing and shearing, dyeing and secondary ironing and shearing. According to the method, the traditional skinned skin concept is broken through, softening, pickling and tanning are completed in one bath, the density of fibers on a skin plate is controllable, and high-density sheared sheep velvet is formed; a new process system for synthesizing a tanning agent by using a BASF environment-friendly new auxiliary agent is established, and the traditional skinned leather concept is changed, so that the three working procedures of softening, pickling and tanning are condensed into one working procedure and one bath for tanning; according to the innovation point, the use number of equipment is reduced, the production time is shortened, the water and electricity use amount is saved, and the productivity is improved; meanwhile, a traditional natural airing method is abandoned, the drying room is invented, sheepskin is shrunk at high temperature, and a new drying process system is formed.

Description

technical field [0001] The invention relates to the field of sheep shearing production and processing, in particular to a high-density sheep shearing production and processing process. Background technique [0002] Merino sheep were first bred in Spain from the 15th to the 17th century. Under the different natural environments and feeding and management conditions in different regions, they were derived from various families of Merino sheep: such as Spanish Merino, French Rambouillet Merino, German Saxon Merino, Australian Merino, American Merino, South American Merino, etc.; Australia is the world's best fur raw material base; where the natural and geographical environment is superior, there are many pastures, and the national stock of about With 160 million sheep, it is known as "the country that rides on the back of sheep". Merino sheep is the most important sheep breed in Australia, accounting for more than 75% of the total sheep stock in Australia. The skin of Merino sh...
