Verfahren zur Erzeugung von permanenten Stretcheffekten auf Wollund Wollmischgarnen bzw.-zwirnen

Improvements in or relating to crimping cellulosic yarns

Crimped yarn is produced by temporarily high-twisting e.g false-twisting, heat setting and back twisting and/or intertwisting one or more chemically modified natural cellulose textile e.g. cotton, yarn(s) or roving i.e. yarn &c. of natural cellulose which has been partially esterified and/or etherified e.g. by acetylation, cyanoethylation or benzylation, with retention of the fibre structure of the yarn, so as to increase the thermoplasticity of the yarn. Heating means for setting the yarn may comprise an electric coil which heats the air in a tube through which yarn passes, a box with heating coils through which yarns pass at different points, or a metal contact surface. The crimp may be fully developed by immersion of skeins of yarn in hot water under tension-free conditions.

Process of obtaining elastic fabrics

Elastic yarns and methods of preparing them

Yarn containing keratinous fibres is crimped by twisting the yarn, setting the twist by treatment with a reducing agent, and then untwisting at least some of the imposed twist. Keratinous fibres mentioned are various animal wools and they may be blended with non-keratinous fibres, for example cotton, rayon, cellulose acetate and triacetate, vinyl, acrylic, polyamide and polyester fibres, to produce a single or multi-ply yarn to be crimped. The imposed twist may be in the same direction as, or in the opposite direction to, the original twist in the yarn while the back twist may be greater or less than the imposed twist. In an example the yarn is twisted and wound on to a perforated dye spindle which is immersed in an aqueous solution containing 1% sodium bisulphite. After ten minutes excess reducing agent is drained from the yarn and the yarn is then steamed for a further ten minutes. The yarn is then rinsed, optionally dyed, dried in an oven at 80 DEG C, and then entwisted on to another ...

A compound yarn, in which high stretch and bulk properties due to helical crimp may be developed when the yarn is released, is produced by intertwisting at least two " thermoplastic " yarns, the doubling twist being in the same direction as the twist in the component yarns, setting the doubled yarn in the twisted condition, and then reverse twisting the doubled yarn to an extent which exceeds the original doubling twist so as to leave a reverse twist of at least four turns per inch in the compound yarn. The remanent twist is dependent on the count, and increases with the fineness, of the yarn. The component yarns may be staple and continuous filament yarns of acrylics, polyamides or polyesters, or of wool. The doubled yarn may be set and/or relaxed under dry, moist or wet heat conditions.

Improvements in or relating to yarns

A synthetic multifilament yarn has filaments of different deniers, with at least one filament having a denier greater than 6 and is crimped by twisting, heat setting and untwisting - for example by false twisting. The yarn, which may be composed of a polyamide, polyester or a polyolefin, may be covered - for example by core-spinning or by wrapping - with staple fibres of wool, cotton, regenerated cellulose, or polyacrylonitrile, and/or plied with a further similar multifilament yarn. In examples the yarn has 2-4 filaments of a denier between 8 and 20 and 12-20 filaments of a denier between 2 and 5. Individual filaments of different cross-sections may be used. Yarns consisting of trilobal filaments or containing at least one hollow filament can be used. The plying and covering steps may be carried out on a ring-twister, or an up-twister with or without a hollow spindle.

1,053,758. Surgical sutures. ETHICON Inc. Oct. 25, 1963, No. 42208/63. Heading A5R. [Also in Divisions B5 and D1] Surgical sutures are made from a round collagen strand of uniform cross-section throughout its length, made by stretching and simultaneously twisting a multiplicity of extruded wet collagen monofilaments under controlled conditions of humidity to wring out a controlled amount of moisture and to bond the monofilaments into a unitary structure, drying the monofilaments while in the twisted condition, and removing the twist. Monofilaments are defined as single threads of collagen fibrils as extruded through single spinneret orifices. The wet collagen monofilaments may be obtained in the form of a ribbon, i.e. a thin film of collagen fibrils as extruded through a slit, the wet collagen ribbon twisted to wring out excess moisture, dried while in the twisted condition to form a bonded unitary structure of circular cross-section, and the twist removed. In a preferred method, a collagen dispersion is de-aerated, aged for 31 hours at 25‹C. and 16 hours at 5‹C., and spun from the reservoir 114 under a pressure of 15 1bs. The dispersion is pumped through the homogenizing jets 116 and 117 and the filter to the spinneret and is extruded upwardly into the spinning column which contains a continuously circulating acetone dehydrating bath 145, the filaments passing over idler pulley 137 and around guide 138 to the godet 101. The collagen filaments are wrapped three times around godet 101 before passing to the first stretching stage. Three wraps suffice to prevent slippage because the collagen is wet at this point. In the first stretching stage, between godets 101 and 102, the filaments are twisted. by false twister 112 to improve their tensile strength and thus prevent breaks during processing, and also to wring out the moisture. which is further removed by the heater-blower 133, adjusted to give an indicated tension of 45 to 50 gms. on the tensometer 142.
