Abstract:
An industrial double-layer structured fabric comprising:an upper layer fabric woven of upper layer warps and upper layer wefts,a lower layer fabric woven of lower layer warps and lower layer wefts,binder yarns that connects the upper layer fabric and the lower layer fabric, andan auxiliary weft that passes over two or more adjacent upper layer warps and does not pass under the lower layer warps, and that is arranged between upper layer wefts, to form a paper making surface,wherein the binder yarns comprise a first and second binder yarn that are respectively arranged on either side of the auxiliary weft,wherein the first binder yarn passes over two or more adjacent upper layer warps to form a paper making surface, and is located above an upper layer warp in a portion of the double-layered structured fabric where the auxiliary weft is located below the same upper layer warps, andwherein a second binder yarn passes over two or more adjacent upper layer warps to form a paper making surface, and is located above an upper layer warp in a portion of the double layered structured fabric where the auxiliary weft is located below the same upper layer warps, and the second binder yarn passes below a lower layer warp in a portion of the double layered structured fabric where the first binder yarn is located above an upper layer warp and forms a paper making surface, and is located above an upper layer warp in a portion of the double-layered structured fabric where the first binder yarn is located below a lower layer warp.
