Processing method for sheared sheep skin leather

Abstract

The invention discloses a processing method for sheared sheep skin leather. The method comprises the step of performing board shrinkage on a piece of sheared sheep skin subjected to preparation, wherein a roll coater is used, a shrink agent is added into the roll coater, and is coated on the sheared sheep skin leather by the roll coater, and then the leather is subjected to still standing, backwater, drying and finishing to obtain a sheared sheep skin product. According to the method, the roll coater is used to uniformly coat the shrink agent on the sheared sheep skin leather, and the shrink agent enables the leather to shrink, and can fully permeate into the leather through the still standing of the leather, so that the leather can shrink further to obtain required sheared sheep skin with higher wool density, and a problem that raw materials of the high-density sheared sheep skin are less, which limit the mass processing and production of the required sheared sheep skin leather with higher wool density in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a method for processing sheep shearling leather. Background technique [0002] The processing of sheep shearling leather is usually divided into three stages: preparation, tanning and finishing (also known as finishing). In the previous finishing stage, some basic methods such as drying, flattening, softening and grinding were used to ensure the quality indicators of the wool quilt, such as hue, straightness and looseness. When processing some products that require higher wool density, For example, sheep shearling bed blankets can only be processed by manual selection of fur materials with high wool density. Due to the limited raw materials and uneven wool density, it is not suitable for batch processing to produce the required wool density. higher product. [0003] To sum up, how to process the desired leather products with higher gross density in batches is an urge...
