Techno-Economical Evaluation of Textured Viscose Rayon Yarns

Viscose rayon was developed as a man made replacement for the most favourable natural cotton fiber. It was textured by mechanical mode texturising systems, viz; air jet texturising and mechanical crimp texturising due to its non thermoplastic nature. The product yarns were verified for various structural, mechanical and texturising characteristics. Air jet yarn had shown higher bulk, loop size and loop frequency. However it lagged in terms of mechanical properties, stability of textured configuration from mechanical crimp textured yarns. Unlike air jet textured, mechanical crimp textured yarn denier was found almost identical to parent yarn. Mechanical crimp texturising has economical proficiency over air jet texturising due to obviation of cost adding factors from the process.
