The use of cashmere-like acrylic fiber as a material for the production of acrylic wool tops according to the characteristics of acrylic fibers is carried out by special processing methods. Since 1999, Shanghai Jinyang Acrylic Fiber Factory has developed fine fiber into new product development projects. In the following year, it has been put into production in batches. According to the use opinions, after many technical improvements, qualified cashmere wool tops have been produced and accumulated. The manufacturing experience has laid the foundation for future production. (1) Selection of raw materials for cashmere-like acrylic fiber: Cashmere is characterized by soft and smooth handfeel. The use of acrylic fiber to produce cashmere to achieve the effect of cashmere, the choice of raw materials is the key. According to foreign data, the fineness of single fiber should be finer than conventional. (2) Production process and quality of cashmere-like acrylic tops: The two-strand tow production process is a pull-off method. Production was carried out on the imported MSC-1 type cutting machine, SMC400 type cutting needle machine and SC400 type ball spinning machine manufactured by COGNETEX of Italy. Conventional 3.33dtex as a shrinking top, the rate of performance depends on the needs of the user's products. Fine-denier filaments are used to produce regular tops, which are then blended and combined on a SMC400 re-cutting machine and balled on a SC400 ball-type needle comb. Due to the fineness of the production, the number of fibers on the cross-sectional area of the feed unit is increased, the friction between the needle tip and the fiber is intensified, and the hair particles and the flakes are easily generated, and the hard-nosed plate is formed between the draft rollers; The ultra-long fiber and short-haired content on the machine increased significantly, which affected the production of the spinning mill and increased the amount of wool used. According to the above many problems, respectively, after queuing and sorting research. It is concluded that the comb part of the combing machine is fed by the slack method, so that the top of the comb entering the comb part is negatively drawn and enlarged, and the unwinding pressure is released on the breaking machine. After adjusting the speed of the car, after the technical adjustment process, the weight of the hair was changed and the load of the comb box was adjusted. The defect has dropped significantly. No long fibers were found, and the products were made into sweaters, garments, etc. after spinning. Have achieved satisfactory results. The manufacturing technology of the spinning and tops of cashmere-like acrylic fiber is the first in China. The degree of secrecy in foreign countries is quite high. This trial spinning only relies on several imported wool yarns to analyze and obtain some information. At present, there is no quality evaluation standard in China, and still refer to the quality assessment of FJ533-85 acrylic top quality issued by the former Ministry of Textile Industry.
