Abstract
Abstract The interfilament spacing of stuffer-crimped textile strands is increased by application of fluid circumferentially thereto in a temporarily confining region, such as when the strand travels from the stuffer-crimping region to windup. The strand is false twisted in such processing, the initial direction of twisting being opposite to the direction of any substantial twist in the untreated strand.
