  • Publication number: 20090130936
    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.

  • Publication number: 20090107575
    Abstract: The present utility model provides a mixed fabric, which is woven by untwisted yarns and twisted yarns, the warp yarns are composed by untwisted yarns and twisted yarns, the weft yarns are composed by untwisted yarns and twisted yarns. The twisted warp yarns and the untwisted warp yarns are arranged one by one; the twisted weft yarns and the untwisted weft yarns are arranged one by one. The twist factor of the untwisted yarns is below 200 after untwisting. The untwisted yarns are linear, and its fibers are parallel. The bulgy parts are formed on the surface of the fabric by arranging the untwisted yarns and the twisted yarns. The density of the fabric is between 60 and 800 pieces per 10 CM. Advantages of the present utility model are good structure stability, stereoscopy and high tensile strength. Its softness, bulk, air porosity and hygroscopicity are better than all kinds of the present fabrics have. The weight of the present utility model is light, the surface is smooth.
