Abstract

1,132,523. Nylon filaments. MONSANTO CO. 24 March, 1966 [1 April, 1965], No. 13131/66. Heading B5B. [Also in Division D1] A method of drawing and packaging nylon filament yarn is characterized by forwarding undrawn nylon filament yarn from a source to a draw zone, withdrawing the yarn from the zone at an increased speed to draw the yarn at substantially the natural draw ratio; winding the yarn on a rotating bobbin to form a package of yarn; traversing the yarn along the bobbin at a tension sufficient for package formation; and, after a minor portion of the yarn has been drawn and packaged, increasing the speed of the yarn being drawn and the speed of the yarn wind-up to provide at least a two fold increase in the tension of the yarn being wound; whereby strength loss in the initially packaged yarn normally occurring from texturing thereof is reduced. The preferred material is nylon-66 i.e. polymeric (hexamethylene adipamide); polymeric (hexamethylene sebacamide), referred to as nylon-610, may also be used; as may also polymeric (6-aminocaproic acid), referred to as nylon-6. The process is also applicable to yarn made from nylon-4, nylon-7, nylon-11, mixtures of nylon polymers and copolymers thereof, e.g. nylon 6/66, 6/610/66, and 66/610. While the process is suitable for treatment of yarn whose filaments have a normal round cross-section, yarns having a non- circular or lobular cross-section, or having an axial passage can also be used. While a single step involving the required increased yarn speeds and tension will ordinarily suffice, a plurality of steps may be taken periodically such that during each succeeding step increased speeds and tensions are employed. In a preferred method, the yarn is withdrawn from the draw zone at an increased speed to draw the yarn at substantially the natural draw ratio; the yarn is twisted and simultaneously and continuously wound on a bobbin to form a package; and after a minor portion of the yarn preferably constituting 1-8 ounces of the resulting package has been drawn and packaged, the speed of the yarn being drawn and the speed of yarn wind-up are increased to provide at least a two fold increase in the tension of the yarn being wound, especially a two fold to three fold increase, without substantially changing the twist being imparted in the yarn. Such drawing may be accomplished by a yarn forwarding means and a yarn drawing means, the latter pulling the yarn at an increased speed to provide a draw ratio of about 1À9 to 5À0. Desirably, the undrawn nylon filament yarn has zero twist, the traversing yarn utilizes a reciprocating ring holding an orbiting traveller which provides on the yarn being wound a tension of about 0À01 to 0À07 g.p.d., and the increased tension on the yarn is about 0À1 to 0À4 g.p.d. Under such conditions, the twist is desirably about 0À1 to 0À5 turns per inch on the yarn. Examples are given. The process of the invention enables a false-twist textured nylon yarn having improved strength uniformity and improved dyeing uniformity throughout its length to be made.
