Abstract

Relates to the manufacture of artificial silk, artificial horsehair, &c. by the dry or evaporative method from solutions of cellulose acetate or other organic esters of cellulose, and of cellulose ethers. Spinning solutions of a concentration not less than 20 per cent, for example, of 25-30 per cent strength, are employed; by employing these high concentrations the filaments are stronger and of rounder section, show less tendency to crinkle or turn woolly, and not show, especially in the case of cellulose acetate, the effect of "glitter." The use of solutions containing toxic chlorine derivatives is excluded. Reference has been directed by the Comptroller to Specifications 20979/11 and 182,166.
