Abstract: The invention relates to a method for producing a towel, specifically a low twist towel, comprising the following steps: Z twisting a thick yarn and separately Z twisting a fine count yarn; unevenly S twisting the Z-twisted yarns to make the volume of the thick yarn more than that of the fine count; weaving the yarn to produce a fabric; processing the fabric with hot water to reduce inner tension in the yarn and make the fabric become fluffy. Fabric produced by this method can solve the dependency on PVA, reduce energy consumption and material consumption, and prevent water pollution. This method for producing a low twist towel is environmentally friendly, healthy, and energy saving.

Abstract: A yarn false twist texturing apparatus having a plurality of side by side processing stations for texturing a plurality of thermoplastic yarns, wherein at each station a first feed system withdraws the yarn from a feed yarn package, and advances the yarn to a false twist zone composed of a heater and a cooling device, as well as a twisting unit. A second feed system withdraws the yarn from the false twist zone and advances it to a takeup device. The cooling device includes a cooling tube, with the yarn spiraling in contact with its outer surface. For an intensive cooling of the yarn according to the invention, the cooling tube is cooled from the inside with a coolant flow, which flows in a direction opposite to the direction of the advancing yarn.

Abstract: A method and apparatus for producing randomly variegated multiple strand wrapped yarn in twisting together two or more yarns at a plurality of yarn twisting stations. At each station a pneumatic twisting head is disposed in which randomly turbulent air currents are created in a chamber in the twisting head by compressed air flowing into the chamber from a manifold through bores in the twisting head, thereby randomly twisting together two or more yarns in the chamber.

Abstract: A method and apparatus for producing randomly variegated multiple strand yarn in twisting together two or more yarns at a plurality of yarn twisting stations. At each station a pneumatic twisting head is disposed in which randomly turbulent air currents are created in a chamber in the twisting head by compressed air flowing into the chamber from a manifold through bores in the twisting head, thereby randomly twisting together two or more yarns in the chamber. The yarns which have been twisted together are taken up over a plurality of traversing drums commonly mounted on a shaft which is driven by an alternating electric current motor controlled by a control device which operates to start and restart the motor on a predetermined cycle including a variation of the electrical input sufficient to result in randomly unpredictable inertia resistance of the traversing drums to rotational speed variation, thereby creating randomly unpredictable take-up of the yarns to produce non-uniform random twist in the yarns.

Abstract: A process for treating a ply-twisted crimped multifilament yarn. The process involves adjusting the temperature and moisture content of the yarn prior to passing the yarn through a stuffer box which is essentially free of steam. Excess hot fluid is removed from the yarn, and the yarn's temperature is adjusted to a temperature in the range of about 40.degree. to 90.degree. C. before the yarn is passed through the stuffer box. The yarns may be used for making a textured saxony-type carpets having a tightly tailored surface texture.

Abstract: Synthetic yarn and yarn-like structures are formed by the method of treating separate multifilament strands of thermoplastics material so that at least one has a shrinkage ratio higher than normal at an elevated temperature. The strands are intermingled in a gas stream with formation of loops on the strands after which they are subjected to a twisting force which imparts a random form of twist on the intermingled formation followed by a heating operation to cause them to shrink differentially while being held until shrinkage ceases so that interlocking bud-like projections form on the filaments.

Abstract: A direct current electromagnetic disc type tension control which periodically has the D. C. voltage increased from low voltage to high voltage and the high voltage is driven to zero a successive predetermined number of times to vibrate the tension discs in order to break the contact between the tension discs and between the tension discs and the electromagnet to lower the resistance to rotation of the discs.

Abstract: A specially designed multifilament textured yarn has alternating twists therein. A woven or knitted fabric manufactured from the yarn has a handling similar to that obtained by a hard twist yarn or a true twist yarn and provides pattern with a heather like feeling.In the yarn, S-twist yarn portions and Z-twist yarn portions are alternatingly distributed along the length of the yarn but the non-twisted portion is substantially not included in the yarn. Either S-twist yarn portions or Z-twist yarn portions have a compact twist yarn structure, and the other portions have a bulky twist yarn structure.

Abstract: Method and apparatus to produce a continuous filament textured yarn with unusually low crimp contraction and intermittent crimp and molecular orientation along its length. This is accomplished by the use of an electromagnetic tension device to control the draw in the yarn being supplied to a false twist device driven at a speed to provide low false twist in the yarn being twisted. The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides as it passes to a yarn consuming machine.

Abstract: A direct current electromagnetic disc type tension control which has alternating current superimposed on the direct current circuit to allow the electromagnet to vibrate the tension discs in order to break the contact between the tension discs to lower the resistance to rotation of the discs by the yarn passing therethrough. The direct current circuit includes a source of high voltage and a source of low voltage and the current from the low direct current voltage source is cut off periodically and momentarily.

The direct current electromagnetic tension control is an electromagnetic disc type tension control in which the yarn guiding post is slotted off-center between the discs so that the yarn being tensioned is received between the discs and exerts a torsional force on the tension discs to cause the tension discs to rotate in order to enhance the dissipation and self-cleaning of the yarn finish accummulated therebetween.

Abstract: The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides to a yarn consuming machine. The balloon control basically employs a bar member under which the yarn passes as it is delivered to a yarn guide tube. The bar member prevents the yarn from rotating as it is taken off over-end from the yarn package thereby alleviating the possibility of yarn entanglement at the yarn tube.

Abstract: A multifilamentary polymeric yarn capable of undergoing false twist texturing is passed through a friction disc aggregate under conditions (as defined) which produce periodic slippage with respect to the friction disc aggregate whereby recurring relatively tightly twisted areas measuring approximately 0.125 to 1.25 inch are substantially maintained along the length of the yarn intermediate recurring textured areas measuring approximately 0.125 to 1.25 inch which include a twist in the opposite direction. The feed yarn may be either partially oriented yarn or a drawn yarn. In a preferred embodiment the feed yarn is a partially oriented polyethylene terephthalate multifilamentary yarn. Unmodified texturing machinery can be employed. The resulting yarn is space textured and may be utilized to form a crepe fabric having highly desirable aesthetic characteristics.
