| Abstract: | Conclusions The possibility of obtaining a viscose fibre with increased strength up to 25–28 cN/tex, and improved fatigue properties, a low-shrinkage fibre, or a fibre with less loss of strength in the wet state has been demonstrated under experimental conditions. The process of preparing a crimped viscose fibre has been checked out under manufacturing conditions.Eliminating zinc sulfate from the technological process and reducing the specific norms for consumption of sulfuric acid (thanks to the use of precipitation baths which are less concentrated in sulfuric acid) and for neutralizing agents affords an opportunity to reduce contamination of wastewater and to obtain ecological and economic benefits.Translated from Khimicheskie Volokna, No. 6, pp. 16–18, November–December, 1986. |
