Chemical yarn and fiber are the main raw materials of the textile industry. The launch of chemical fiber production in Uzbekistan will increase the range of fabrics, knitwear, non-woven fabrics. This article is devoted to the study of the possibility of obtaining fiber from different mixtures of primary and domestic polyethylene terephthalate granules purchased from abroad, by dyeing and reducing its specific surface electroplastic resistance under laboratory conditions. The possibility of dyeing the fibers in the mass with a “masterbach” and in solution with a disperse dye – all those possibilities have been thoroughly studied in the present article. It is shown that the coloristic performance of the color formed in the fiber depends on the dyeing method used. Dyeing of polyethylene terephthalate (PET) fiber in solution and application of antistatic coating in a two-bath method reduced the specific surface electrification resistance of the fiber from 2.8 ∙ 1010 Ohm to 2.6 ∙ 106 Ohm. A mixture of different PET granules was proposed to form a fiber suitable for textile yarn in a dry method in an experimental laboratory device and dye it in solution and give an antistatic make-up bath.
