abstract

At the knitting enterprises of the Republic of Belarus, the assortment of manufactured products is constantly updated, new types of raw materials are being searched that satisfy the producer in terms of quality and price. The work was done to verify the possibility of using of a viscose air-jet yarn (Vortex®) of a linear density of 20 tex in knitting production. The complex analysis of the properties of the yarn showed its compliance with the world analogs, the quality index according to Uster Statistics USP is 6–25 %. The yarn is characterized by higher strength and elastic properties compared to the rotor spinning yarn, which is a closely related kind. Significant difference in the price factor is not observed. According to the results of the research, Vortex® yarn can be recommended for knitting enterprises to expand the range of products.
