Abrasive Patents (Class 26/28)
  • Patent number: 5815896
    Abstract: A method and apparatus for loosening, cutting, and abrading a web of textile fabric having spun yarns containing wrapper fibers. The textile fabric web is directed under high tension around pairs of rotatable, small diameter tubes coated with abrasive particles. Abrasive particles are preferably rounded (nonfaceted) tungsten carbide particles. The tubes (rolls) are rotated at differing speeds in relation to the fabric web speed through the apparatus. Preferably, the first, regressive roll rotates at a speed slower than the web speed and the second, progressive roll rotates at a faster such speed. Such a process and apparatus provide improved conditioning and napping of a fabric web as well as a quicker, more efficient method of performing such fabric treatment.

  • Patent number: 5505739
    Abstract: The method of the present invention is used to create an overall worn look with areas of heavy wear in specific areas of a new garment's fabric to simulate the wear that occurs from the normal wear of a garment over a prolonged period of time. The method of the present invention comprises the steps of sandblasting the fabric of the new garment to be treated in specific areas in which worn marks simulating areas of heavy wear are desired and treating the entire fabric so that it fades and additional random areas of wear are created. According to the method disclosed, areas of heavy wear occur only in those areas of the fabric which is directly exposed to sandblasting, while the remainder of the fabric obtains a random faded look such that the overall appearance of the new garment simulates that of an old garment that has been naturally worn for a prolonged period of time.

  • Patent number: 5396688
    Abstract: Denim fabric is made from novelty cotton yarn having irregularly spaced irregularities (e.g. slubs) about one-half inch to two inches in length. The cotton novelty yarn is made by separating cotton sliver into cotton fibers, and acting on the cotton fibers with a negative wire combing roll, and then twisting the cotton fibers into the cotton novelty yarn. The negative wire combing roll has a tooth angle of about -0.01.degree. to -15.degree.. The novelty cotton yarn is made into a warp of about 54-100 (e.g. 54-78) ends per inch, and is ring dyed so that the core of the yarn remains white. The warp is woven with a filling yarn to produce a denim fabric with a weight of about 5 oz.-17 oz. per sq. yd. having the weave and yarn size selected so that a tight construction is provided which highlights the slubs. The fabric is subjected to surface abrasion to remove the surface of dye on the slubs to show a lighter slub than body of the fabric.

  • Patent number: 4941239
    Abstract: This disclosure describes a method by which an edge curl that often develops in papermachine forming fabrics can be reduced or eliminated. The method requires the removal of mass from the sheet forming side of the forming fabric. This has the effect of reducing the ratio between the shrink forces acting on the two sides of the forming fabric in the cross-machine direction and, in turn, reduces the tendency for shrinkage to cause the edges of the fabric to curl. Papermachine operational problems associated with edge curl are thereby reduced.

  • Patent number: 4863775
    Abstract: It is possible to produce denim fabric suitable for manufacture into garments that have the look and feel of washed and tumble dried garments, practiced in a relatively simple and quick manner. Denim fabric is treated to raise the warp yarns so that the warp yarns are adjacent the face of the fabric and positioned so that they can be rubbed and abraded to loosen the surface fibers; and then effecting abrading and rubbing of the tips of the warp crimp so as to duplicate the surface abrasion of washing and tumble drying without making a napped or brushed type finish or face. The abrading action may be practiced by sanding utilizing a fine sandpaper in the range of about 50-100 grit, employing a 9-roll T-Ralph sander with 2 to 6 rolls running at a speed of about 50 ydm.
