TECHNOLOGY PROCESS FOR MANUFACTURING ANTI-STATIC WOVEN FABRICS

Abstract

The useful solution refers to a technological process for producing anti-static woven fabric that meets the technical requirements for making protective workwear in the electrical and electronics industries, including the following stages: (i) material selection and fabric design; (ii) weaving; (iii) pre-treatment, dyeing, and finishing of the fabric. The technological process for producing the fabric according to the selected useful solution uses two fiber materials (polyester-cotton blend, blend ratio 83 / 17, Ne count 45 / 2 and conductive fiber, polyester-cotton blend, blend ratio 65 / 35, Ne count 54 / 1 spun with 25D polyester fiber containing carbon particles); the carbon particles in the 25D polyester fiber are the anti-static agent; the selection of these two materials and the design of the weave, the development of weaving technologies, pre-treatment, dyeing, and finishing of the fabric do not degrade the anti-static properties of the conductive fiber. The useful solution also mentions anti-static woven fabrics with the following distinct functions: - Fabric surface resistance (Ω): 1.10 6 -1.10 12 .- The fabric's anti-static properties remain intact after multiple washes; - No dust is generated in the production workshop; - Wash fastness, 40°C (grade) ≥ 4; - Friction fastness (grade) ≥ 3-4; - Fabric shrinkage (%) ≤ 3.
