Abstract: Yarn is treated in an air entangling apparatus having a yarn introducing guide tube through which one or more yarns are fed, a central bore positioned so that the yarn guiding tube enters it at an angle, and an air jet blowing into the central bore substantially at right angles to the axis thereof. The central bore extends through the texturizing block, and the air jet causes air to leave at both ends of the bore. The yarn continues through the bore, leaving at the downstream end. Overfeed of the yarn is kept at a fairly low point, from a fraction of a percent to a maximum of about 10% and the air pressure is also moderately low, preferably from about 6 psig to 12 psig. At least one of the yarns used is a multifilament yarn and treatment with the present apparatus entangles or interlaces the filaments. If two or more yarns are employed, the product is a plied yarn.

Abstract: 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.
