Description

technical field [0001] The invention relates to a tunnel type super (sub)critical CO 2 A waterless wool scouring device belongs to the field of wool scouring equipment. Background technique [0002] The purpose of wool scouring is to remove dust, sheep sweat, dirt, grease, etc. from wool, and to obtain scoured wool without tangles or felting. Scoured wool is the basis of wool spinning products, and the quality of scoured wool has a significant impact on subsequent processing. During the growth of sheep, on the one hand, due to the influence of the feeding environment, the wool is rich in mineral and vegetable impurities, such as sand, various grasses, feed, etc. On the other hand, the sweat, fat, dander, and feces excreted by the sheep during the growth process are also attached to the wool. The content of residual pollutants on the surface of scoured wool affects the whiteness, dyeability and drawing and spinning performance of scoured wool; the looseness and damage of s...
