Few can dispute the tremendous values of linen, which is one of nature’s greatest treasures. Linen is a longer-staple category, and as such the fibre is spun on a long-fibre spinning system. Due to the coarseness and stiffness of the fibre, linen fabrics are subjected to a strong bleaching action to reduce the stiffness of the fabric. Linen is also blended with other compatible natural and manm...

Hanninen, H. (1971). Brit. J. industr. Med., 28, 374-381. Psychological picture of manifest and latent carbon disulphide poisoning. A battery of psychological tests was administered to 50 viscose workers with carbon disulphide (CS2) poisoning, 50 viscose workers exposed to CS2 without known poisoning, and 50 workers not exposed to CS2. There were large and statistically significant differences ...

Effects of coagulation temperature, coagulants, and wet-spinning methods on structure and properties of novel regenerated cellulose (RC) fibers prepared from cellulose in 7.5 wt % NaOH/11 wt % urea aqueous solution on pilot scale spinning machine by oneand two-stage coagulation were investigated by tensile testing, optical microscopy, scanning electron micrograph, and wide-angle X-ray diffracti...

Anisotropic nanomaterial-modified carbon fibers attract increasing attention because of their superior properties over traditional ones. In this study, activated carbon fibers (ACFs) "thickly overgrown" by Ag nanohair were prepared through self-assembly and rapid thermal annealing. Viscose fibers with well-dispersed silver nanoparticles (AgNPs) on surfaces were first prepared through self-assem...

Artificial silk is made by the viscose process in Hungary. Systematic air analyses and medical surveys have been carried out in a viscose rayon factory for the purpose of studying the maximum allowable or toxic concentration ofcarbon disulphide. In view of the fact that widely varying concentrations may give misleading results, we have not drawn any conclusions from the investigation of persons...

compared with those ofboth the general population and a cohort of viscose-rayon workers. Ratios of observed to expected deaths for lung cancer in the two industrial populations (65 observed) were found to be elevated in both comparisons (1.4 in respect of both the general population (95% confidence interval (CI), 1. 1 1.8) and the viscose-rayon workers (1.0-2.0)) and tended to be concentrated i...
