  • 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: 7882857
    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.
