Abstract
Textile strands are bulked or crimped by lengthwise compression, accompanied by flow of propellant fluid, into a foraminous region in which the strand is confined laterally but the fluid may escape except where the strand is compressed into a compact mass. Lateral escape of the propellant fluid is utilized to control an operating condition, such as temperature of strand input into and/or speed of removal of strand from the chamber, for improved uniformity of bulking or crimping.
