Textured yarn product

摘要

Multifilament synthetic polymer yarn is texturized by passing the yarn in a gas stream to a diffuser zone to cause the gas to expand and the yarn filaments to splay open. The yarn filaments are then separated from the expanding gas stream towards a continuous smooth side wall surface defining one end of a bulking chamber. At this end of the chamber the filaments are impacted with each other and the smooth wall surface to form a compact yarn mass. This yarn mass is pushed into and through a slotted portion of the bulking chamber. Simultaneously the gas passes through the yarn mass initially formed in the chamber and then discharges laterally from this mass as it is pushed into the slotted portion.
