  • Patent number: 7896035
    Abstract: In an industrial multilayer fabric, narrower wefts of a small diameter are placed between lower side wefts so as to sandwich a knuckle formed by a lower side warp on the lower surface side of the fabric. The industrial fabric is obtained by stacking at least upper side wefts and lower side wefts one after another and weaving these wefts with warps. Narrower wefts that have a smaller diameter than that of the lower side wefts and form a shorter crimp than that formed by the lower side wefts on the lower side surface are arranged between the lower side wefts. And at a knuckle portion formed by warps passing under one or two successive lower side wefts, the narrower wefts form a crimp passing under lower side warps so as to sandwich, from both sides, one knuckle or two knuckles formed by two adjacent warps under two adjacent wefts.

  • Patent number: 7874321
    Abstract: Each of lower side wefts of an industrial two-layer fabric passes over three successive lower side warps and then under the remaining two or more lower side warps thereby forming a lower side weft design including a lower-side-weft long crimp. The lower side layer of the fabric is formed by arranging lower side wefts adjacent to each other while repeatedly shifting the weft design according to one of the following shift patterns: shifting by three warps; shifting by four warps; shifting by five warps; shifting by one warp and then four warps; shifting by three warps and then four warps; shifting by two warps and then five warps; shifting by one warp and then six warps; and shifting by one warp, four warps, five warps, and then four warps. The lower-side-weft long crimp of the lower side layer has a rectangular shape.

  • Publication number: 20110011485
    Abstract: The industrial two-layer fabric has at least warp binding yarn pairs having an upper side warp and a warp binding yarn arranged vertically. On the upper side, between knuckles that two adjacent upper side warps have formed by passing over one or two upper side wefts, a warp binding yarn passes over one upper side weft to form a knuckle, whereby knuckles of the upper side warp, the warp binding yarn, and the upper side warp are formed in the mention of order over the one upper side weft. In the industrial two-layer fabric thus formed, the knuckle of the warp binding yarn does not protrude further than the knuckle of the upper side warps.

  • Patent number: 7819141
    Abstract: A two layer fabric has first, second, third and fourth upper side wefts contiguously and repeatedly arranged. Each of three contiguously arranged warps forms a knuckle over second, over third, and over second upper side wefts respectively to form a separation portion. At both sides of the separation portion, both the second and third upper side wefts form a float portion by passing over two or more warps. Adjacent to the float portion, one warp passes over the second and third upper side wefts successively and one or two warps adjacent thereto pass over the second or the third upper side weft to form an approach portion where the second and third upper side wefts approach. Crimp portions are formed to sandwich the separation portion where the first and fourth upper side wefts pass over warps which are common to those of the separation portion.
