FIBERS BASED ON PVC / PVC CHLORINATED MIXTURES WITH IMPROVED MECHANICAL PROPERTIES AND IMPROVED TENACITE FIBER YARNS OBTAINED FROM THESE FIBERS.

摘要

P Cut fibers based on an atactic PVC / chlorinated PVC mixture containing 17 to 20% of superchlorinated PVC, characterized by the fact that they have a titre on the strand = 2.3 dtex and a residual shrinkage after treatment in oil at 115 ° C for 30 min according to ASTM D 210262 T = 6%. BR/ Such fibers are suitable for obtaining lower titre fiber yarns which are strong enough to be used on high speed weaving machines. / P
