  • Publication number: 20090093184
    Abstract: A method for incorporating optical fibers into sheet materials, such as fabrics, creates a structure which can be incorporated into items such as plush toys. Optical fibers are made to pass through the sheet material in a desired arrangements. Ends of the optical fibers are enlarged such that they will not readily pass back through the fabric.

  • Patent number: 6065277
    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: 4598441
    Abstract: There is provided an apparatus for the manufacture of absorption pads for sorbing body fluid which is composed of two substantially identical so-called flake applicators each including a vacuum cylinder having shaped recesses which are so-called flake wheels. A first component layer of the absorption pad is produced on the first flake wheel and a second component layer is produced on the second flake wheel. The component layers produced on the first flake wheel are applied to the component layers produced on the second flake wheel by means of a transfer roll. A second transfer roll lifts the finished absorption pad from the second flake wheel and delivers the absorption pad by means of a vacuum belt to a machine for further processing.

  • Patent number: 3943605
    Abstract: A fluff pad for an absorbent product such as a diaper, sanitary napkin or the like is formed by superposing two layers of fluff top-to-top. The layers are formed separately but simultaneously on conveyor wires. The non-wire side of a layer is the "top". Each layer is scarffed and debulked. One layer is removed from its wire by suction and placed with its wire side engaging a wrap sheet traveling beneath the wire on which the second fluff layer is formed. The second layer is removed from its wire by applying suction from beneath, through the wrap sheet and first layer to deposit the second layer on the first in inverted relation. An additional dispersion sheet may be added between the fluff layers, if desired.
