    Abstract: The present invention concerns a kind of ply yarns and the ply yarns fabric. One piece of the ply yarn is intertwisted by one piece of untwisted yarn and one piece of twisted yarn or filament in the direction of the length. The twist factor of the untwisted yarn is below 200, and the fibers of the untwisted yarn are parallel. In the present invention, the ply yarns fabric is woven by the ply yarns. The present invention adopts the ply yarns to make the ply yarns fabrics. The fabrics contain warp yarns and the weft yarns which form the noumenon of the fabrics. One piece of the ply yarn is intertwisted by one piece of untwisted yarn and one piece of twisted yarn or filament in the direction of the length. The twist factor of the untwisted yarn is below 200, and the fibers of the untwisted yarn are parallel, the untwisted yarns are linear, so that the bulgy parts could be formed on the surface of the fabric.

  • Patent number: 7223471
    Abstract: A composition comprising Polytrimethylene terephthalate (PTT) with a reduced emission of acrolein is obtained by contacting Polytrimethylene terephthalate (PTT) resin with an effective amount of a melt stable, organic stabilizing compound. Such PTT resin has an acrolein formation rate at 280° C. of less than 15 ppm/minute. Preferably the residual acrolein content of the PTT resin is less than 10 ppm. The additive organic stabilizing compounds are free from nitrogen atoms. Preferred additive compounds include polyfunctional alkohols, alcoholates, aromatic carboxylic acid anhydrides, carboxylic acids and salts of carboxylic acids. The additive compounds are added to the polymer in molten state and/or to the resin, which is then processed to fibers, filaments, non-wovens, films and/or mouldings.

  • Patent number: 7199065
    Abstract: The present invention provides non-woven laminate that is not subjected to final consolidation by a binder and the production thereof. The laminate includes at least one non-woven mat containing glass staple fibers pre-consolidated with a resin, and at least one non-woven layer of synthetic fibers. The synthetic non-woven layers and the pre-consolidated non-woven mat of glass fibers are bounded together by needling such that a portion of the fibers of the upper synthetic non-woven layer passes through the non-woven mat of glass fibers possibly through the underlying synthetic non-woven layer. The synthetic fibers are heat shrunken and the laminate is binder free.

  • Patent number: 7196026
    Abstract: An agend fiber composed of an active agent/positive dispensing carrier combination and a fiber forming component. As a fiber or nonwoven or textile fabric containing the fiber, the agend delivers the active agent at a desired rate under conditions of use. Product applications include personal care products such as diapers, training pants, swimwear, refastenable pants, absorbent underwear, feminine hygiene products, incontinent wear, wound dressings and cleansing wipes. The fibers may be formed as monocomponent fibers or multicomponent fibers of varying configurations. Active agents that can be dispensed include skin wellness agents, therapeutic agents, and cleaning agents, for example. In accordance with the invention, agend fibers provide desirable uniformity of dispensing and control of dispensing rates.
