[0018] The method for preparing lightweight wool yarn for woolen spinning includes the following steps:
[0019] 1) First, add the oil-water and antistatic agent in the ratio of 1:1:4 to the wool mixture containing selected 5-6cm crimp, wavy and elastic wool raw material and 4D chemical fiber to make the fiber Swelling to maintain sufficient crimp and elasticity, wool and chemical fibers are fully mixed, and placed in a sealed storage warehouse at room temperature for 24 hours. The content of wool raw material is 30%. Specifically, it can be 66S with good curl and elasticity. Connaught wool or 66s Australian wool. 2). The wool mixture after moisture absorption is repeatedly combed on the elastic card cloth OCTIR carding machine → taken out, cyclically combed, and the gap between the rollers is controlled to relax to about 14 filaments to prevent the fiber from being straightened. , To keep the original space and bulkiness between wool and chemical fiber, so as not to be damaged ...
