Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2023 / V.35,no.1,Mar Title The Effect of Manufacturing Conditions of Coated Yarn Using Anti-Static Thermoplastic Polyurethane M/B on Anti-Static Resistance Authors Yedam Jeong, Jieun Kwon, Sunmin Kwon, Seehyeon Chae, Hyunjea Cho, Wooseok Kim, Mikyung Kim, and Jongwon Kim Institution/Affiliations Yeungnam University, Polysys Co., Ltd., DYETEC Pages/Total page pp.20 ~ 28 / 9 Language Korean Abstract In this study, TPU resin for coating was prepared by varying the mixing ratio of antistatic TPU and recycled TPU to manufacture permanent antistatic materials. The coated yarn was prepared by coating on the nylon yarn, and then the thermal, rheological, mechanical properties and antistatic properties were analyzed. In addition, antistatic properties and durability were confirmed after manufacturing UD fabrics using coated yarns. The mixing ratio of antistatic TPU and recycled TPU was most appropriate at 4:6, and the antistatic property had a surface resistance of 2.20 × 109 Ω and a static charge of 398 V. In the coating process, the coating speed was most appropriate at 0.21 m/s, and the surface resistance of the UD fabric manufactured with the coated yarn manufactured under this condition was 6.80 × 109 Ω and the static charge was 484 V. The UD fabric had a surface resistance of 7.21 × 109 Ω and a static charge of 517 V after washing 10 times, and it was confirmed that the permanent antistatic property was excellent.
