Technical Field

The invention relates to the technical field of wool washing and carding, in particular to a low-damage superfine wool washing and carding method.

Background

The superfine wool is homogeneous sheep wool with the average diameter of 16.5 ~ 19.5.5 mu m or less, the wool is fine, soft, curly and uniform, the length is 65 ~ 95mm, and the superfine wool is suitable for spinning high-grade fabrics.

The scales on the surface of the conventional wool fiber are annular or cracking, are arranged thinly and are easy to cling to a hair shaft, so that the surface of the fiber is smooth and has strong luster; the superfine wool fibers are thin, the scale on the surface is arranged closely, clearly and orderly, most of the superfine wool fibers are in an annular horizontal shape, the edge of the scale is obviously tilted, the light reflection is small, and the luster is soft. Wool scouring is the first step in the manufacture of wool tops, and about 40% of natural dirt in raw wool needs to be removed. The purpose of washing the hair is to remove impurities such as grease, sheep sweat, grass scraps and the like in the raw hair by a mechanical and chemical combined method to obtain the white and soft washed hair. However, the existing alkaline wool washing and acid wool washing can cause damage and yellowing to the superfine wool. The damage caused to the fibers by the carding process is mainly mechanical damage, the most obvious damage being the breakage of the fibers. The fibers are stressed at different parts during carding to generate slow elastic deformation, so that the tensile strength and the bending rigidity are reduced.

In order to solve the problems, the application provides a low-damage superfine wool washing and carding method.
