    Abstract: Intermittently colored yarns having an intermittent and random dye spacing pattern, and systems and methods of making the same, are disclosed. Such intermittently colored yarns exhibit higher quality and lower manufacturing costs over the known intermittently colored yarns. The intermittent coloring takes place while the yarn is in caterpillar form. Carpets made from such intermittently colored yarns exhibit enhanced aesthetics over carpets made from known intermittently colored yarns. Alternatively, a stain resist, colorless base dye, or bleaching agent can be applied in the same intermittent and random spacing pattern to the intermittently colored yarns prior to subsequent dyeing. This creates a mirror image like color effect to the resulting yarn.

A plurality of bores are provided in the body which extend from the periphery of the body to intersect the central passageway, being tangentially disposed with respect to the central passageway. Fluid under pressure is introduced into the bores, and creates a vortex action which acts upon the yarn to twist and lay down protruding hairs that cause yarn hairiness. The bores are preferably disposed at an angle of about 40.degree.-50.degree. with respect to the central passageway, and are spaced along the length of the passageway. Shortly after the yarn exits the body, hot melt sizing is applied to it to maintain the protruding hairs in their laid down position.

Fabric manufactured from such yarn is then subjected to a finishing process, in which enzymes capable of breaking down the corn starch and a wetter/rewetter are added to the fabric itself. These enzymes are activated during a subsequent soaking in water only, followed by agitation, whereby stiffness may be removed from the fabric in approximately 5 minutes. In accordance with another aspect of the invention, softeners are also added to the fabric during the finishing process. The softeners are also released during the subsequent garment washing operation. Preferably, the softeners include at least reactive silicon.

  • Patent number: 4109356
    Abstract: A plurality of synthetic fibrous textile materials such as polymeric yarns and staple fibers are textured by a procedure which imparts a variety of spaced deformations in a random sequence. The fibrous textile materials are fed between two opposed pressure surfaces, one of which has a raised pattern of closely spaced pyramids while the other is made of a resilient material having a meshing pattern of pyramid shaped depressions. The textile material is maintained at an elevated temperature during its passage between the pressure surfaces and is then cooled to give a permanently textured product.

  • Patent number: 4095947
    Abstract: Fabrics of which the warp is sized with water-soluble polymers of acrylic acid and/or their alkali metal salts or ammonium salts, are desized by treating the sized fabric with from 30 to 300 percent by weight of water, based on the dry weight of the fabric, and separating the resulting size solution from the fabric. The recovered size solution can be directly re-used for sizing.

  • Patent number: 4082883
    Abstract: A non-aqueous, water-soluble, quick-setting sizing composition suitable for application in the molten state to textile yarns of both continuous-filament and staple types, and for later removal by aqueous means, comprising a combination of a film-forming thermoplastic polymer with a melt-miscible viscosity reducer and solidification promoter, and yarns so sized. The polymer protects and consolidates the yarn, while its companion component promotes the even application and particularly the quick set-up of the molten size. Optionally, if desired, water-soluble lubricants may also be added to increase the lubricity and flexibility of the sized yarn.

  • Patent number: 4066106
    Abstract: A sizing composition for textile glass fibers comprising a starch, a textile softener, a lubricant and 100 to 150 percent by weight of combined nonionic wetting agents based upon the weight of said lubricant. The glass fibers sized in accordance with this sizing composition has found utility in forming untwisted yarns which are to be subsequently used for the weft of a textile glass fabric.

  • Patent number: RE29287
    Abstract: A compact apparatus and method for applying hot-melt size in a properly fluid state to a plurality of textile yarns. The apparatus comprises an internally heated rotating cylinder made of heat-conducting material, with deep grooves formed around it, one groove for each yarn strand. The size is preferably applied by urging a block of solid size against the grooves of the hot cylinder. From the point of application the molten size is carried by the rotation of the cylinder to a zone where each moving yarn strand passes briefly through a corresponding size-filled groove, essentially tangentially to the cylinder, and then moves away coated with an optimum amount of size. The method of application is unique in its capacity for placing a quick-setting, high molecular weight, film-forming melt size on yarn at high speed.

  • Patent number: T101702
    Abstract: Disclosed are hot-melt polyethylene compositions which are particularly useful as sizing compositions for textile materials. The compositions have a melt viscosity of from about 150 cp at 125.degree. C. to about 6000 cp at 190.degree. C. and may be removed from textile substrates using conventional petroleum based solvents. Useful polyethylenes include those having viscosities of from about 100 cp at 125.degree. C. to about 40,000 cp at 190.degree. C., densities of from about 0.90 to about 0.97 and melting points of from about 95.degree. C. to about 135.degree. C.
