Abstract

The invention belongs to the technical field of sheep shearing bed blanket production, and discloses a clean production method for sheep shearling for high-density bed blankets, comprising the following steps: 1) washing, removing flesh and shearing; 2) soaking in water; 3) ) degreasing; 4) treatment of increasing the gross density: adding the hide into the astringent tanning agent bath, stirring evenly, soaking for 15 hours; the preparation method of the astringent tanning agent bath is: slowly adding 5 grams of sulfuric acid to 1000 grams of In the tanning agent SELLATAN LV conc.liq, stir evenly to make a shrinkage special chemical, and dilute the shrinkage special chemical 50 times with water to obtain an astringent tanning agent bath; 5) Brush chrome; 6) Pickling; 7) Shake 8) dry cleaning; 9) scalding and shearing. The production method of the invention can increase the wool density of sheep shearling to more than 7.

Description

technical field [0001] The invention belongs to the technical field of sheep shearing bed blanket production, and in particular relates to a clean production method for sheep shearling leather for high-density bed blankets. Background technique [0002] In the skin selection process of sheep shearing processing, various factors need to be considered comprehensively according to the requirements of the finished product, such as the width, wool, fineness, etc.; but in addition, there is another important factor that has an important impact on the skin selection. , is the hair density. For example, for leather for backrests, leather for bed blankets, etc., the density of wool is very strict, and the finished product requires more than 7. However, only 2-3% of sheep shearling raw skins can meet such requirements. Therefore, the use of skins is severely limited, and the sorting rate is reduced, which affects the application and production efficiency of raw skins. Contents of t...
