    Abstract: A process for producing dyed spun cotton yarns having a reduced number of irregularities and increased luster is described. The process involves dyeing at least a portion of the cotton fibers which are to form the yarn, then combing the dyed fibers subsequent to the dyeing process. The dyed and combed fibers are then optionally blended with fibers having a visually distinct appearance, and spun into a yarn using conventional spinning methods. The resulting yarns having a dramatically reduced number of thick and thin places and improved yarn properties including improved luster and hand. Furthermore, when the thus-dyed fibers are blended with differently-colored fibers prior to the combing operation, the resultant yarns match the visual colors of like-colored yarns produced by conventional processes, while the color is more intimately blended and the yarns have a markedly increased uniformity, luster and tenacity.

  • Patent number: 4928464
    Abstract: Vacuum spinning of yarn produces yarns having good properties, and which may have a wide variety of different effects and constructions. A core filament yarn may be fed into operative association with a nipped sliver or roving, and then fed to a perforated rotating hollow shaft operatively connected to the vacuum. The core filament yarn may be a full stretched textured yarn, which is placed under tension and while under tension is dragged over a sharp edge of nonconductive material, and after the tension is relieved develops crimp. This causes individual fibers to be repelled, and provides for intermixing of the nipped sliver or roving fibers and the core filament yarn fibers. Alternatively the filament yarn may be acted upon by draft rollers before the entrance to, and after the exit from, the hollow rotating shaft, to apply a force that breaks up to about 20% of the fibers. The yarns produced utilizing the broken fibers has a spun-like appearance.

  • Patent number: 4300344
    Abstract: Multifilament feed yarns in drawable state made from fiber-forming polyester are provided which in accordance with the invention can be processed in a combined draw and false twist process to voluminous filament yarns having individual protruding filament ends. The feed yarns must consist at least in part of filaments having a flex abrasion resistance of less than 1500 cycles and a crack index of more than 5. By using suitable spin finishes, the crack index can be varied and thus the hairiness of the voluminous filament yarns manufactured can be adjusted independently from the crimp values and the pilling behavior.

  • Patent number: 4242862
    Abstract: A polyester yarn composed of a plurality of individual fibrous materials such as endless filaments or fibers. Each of these fibrous material is provided with cross-sectional thicker portions, thinner cross sectional portions and intermediate thickness-size portions randomly distributed along the axial direction thereof in a particular condition of distribution of cross-sections of these fibrous material. The above-mentioned polyester yarn involved a textured yarn applied to a drawn polyester multifilament yarn having the above-mentioned basic condition. To produce the polyester yarn according to the present invention, it is the basic condition that the undrawn polyester multifilament yarn should be drawn under a condition of a drawing ratio below a natural draw ratio of undrawn filaments of said undrawn multifilament yarn and a drawing temperature above a crystallizing initiating temperature of said undrawn filaments.

  • Patent number: 3946548
    Abstract: A multifilament yarn of improved bulkiness is provided. The yarn is composed of two portions, i.e., a relatively dense portion and a blooming, relatively sparse portion, alternately occurring along the length of the yarn. The relatively dense portion is in a partially twisted state and individual filaments in this portion are irregularly entangled and cohere to a greater extent than in the relatively sparse portion. The relatively dense portion has protruding filament ends on the yarn surface in a larger number than the relative sparse portion.The yarn is prepared by first passing a multifilament yarn through a high velocity fluid jet nozzle and then subjecting it to a combination of the steps of false twisting and frictional contact.
