Spinning method for reducing hair shedding of rabbit hair yarn through ring spinning

Abstract

The invention discloses a spinning method for reducing hair shedding of rabbit hair yarn through ring spinning. Coarse rabbit hair yarn is backed off from a coarse yarn roll, passes a tee-joint spreader, and enters a drafting region composed of a rear leather roller, a rear roller, a tee-joint horn mouth, a middle leather roller, a leather collar, a middle roller, a lower leather ring, a front leather roller and a front roller; fiber strands formed after drafting is completed and filaments conveyed by a positioning guide wheel enter a holding stick through a double-hole yarn guider; after thefiber strands and the filaments are held, the fiber strands and the filaments converge and are twisted and wound into yarn. The spinning method has the advantages that the yarn of a specific hybrid-twisted structure can be spun, the wrapping effect of the yarn is good, the yarn has the advantages that hair is fewer and short, the strength is high, and the yarn levelness is uniform, the hair falling rate of the rabbit hair yarn is reduced, and the spinning efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of spinning and relates to a spinning method for reducing hair shedding of rabbit hair yarn by ring spinning. Background technique [0002] Rabbit hair is a precious animal fiber. Rabbit hair is rich in raw materials in my country, and its annual output accounts for 90% of the total output of rabbit hair in the world. The unevenness of wool length is large, the unevenness of linear density is large, the fiber surface is smooth, the friction coefficient is small, there is almost no curl, and the cohesion between fibers is small. Therefore, it is difficult to control the floating fibers during spinning, and it is easy to produce unevenness. Yarn strength is low, end breakage is serious, and spinning is difficult. Rabbit hair is mostly used for woolen spinning, and the proportion of mixed use is low, which limits the further development of rabbit hair products and cannot give full play to the advantages of rabbi...
