Abstract

Artificial filaments, yarns, and the like made of organic derivatives of cellulose are passed through a body of water under super-atmospheric pressure in an end pressure chamber and in substantially non-slipping contact with a driven feed device contained in the chamber and then through saturated or wet steam at a temperature above 100 DEG C. in a steam chamber, and stretching the materials during their passage through the steam chamber. Preferably, the temperature of the steam is at least 130 DEG C. and that of the water not greater than 30 DEG C. The properties of the materials, particularly their tenacity and extensibility, may be varied by varying the temperature of the steam, the relation between the pressure of the steam and the pressure of the water, the degree of stretch, the size and number of the steam inlets, and the length of the steam chamber. Specification 443,707 is referred to.
