Emdadul Haq Lecturer, Department of Textile Engineering, Primeasia University; Bangladesh Viscose Rayon is a man-made, natural polymer cellulosic or regenerated cellulose filament or staple fibre. It is manufactured from spruce wood and cotton linters. Properties of Viscose Rayon Fibre 1. Tenacity and Elongation As the polymer system of viscose fibre is very amorphous, its filaments …
Viscose Rayon Fibre is often referred to as semi-synthetic fibre. It is produced from naturally originated cellulose in the laboratory conditions. That is why it is also called regenerated cellulose fibre. The chemical reactions that are involved in the manufacture of viscose are as follows: Viscose rayon manufacturing: The cellulose is treated with a 17.5% …
Fabric length Fabric length is measured without conditioning and after conditioning of 24 hours. If length difference is found less than 0.25 percent, then the second result is taken as sample length. If the difference is found more than 0.25 percent, then the sample is kept conditioned again for 24 hours and checked the difference …
