摘要： The object of the present invention is to provide an industrial two-layered fabric including binding wefts which is capable of improving a high adhesivity of the fabric on the front and back surface sides and the supportability of the warps, without deteriorating the surface smoothness, the abrasion resistance on the back surface side, the extension resistance in the longitudinal direction and the hydration property, which have been conventionally desired.
The industrial two-layered fabric includes a first pair of warps consisting of a warp on the front surface side that weaves only a weft on the front surface side and a warp on the back surface side that weaves only the back surface side, and a second pair of warps consisting of a binding warp on the front surface side and a binding warp on the back surface side which functions to bind the fabric on the front surface side and the fabric on the back surface side, the one of the binding warp constituting the second pair of the warps consecutively forms a plurality of knuckles on the fabric on the front surface side, while the other of the binding warps does not emerge on the front surface side at a portion where a plurality of knuckles are formed by the one of the binding warp, and the other binding warp consecutively forms a plurality of knuckles on the fabric on the front surface side, while the one binding warp does not emerge on the front surface side, whereby a complementary structure is formed, the diameter of the warp on the front surface side is set to be substantially the same as the diameter of the binding warp, and the diameter of the warp on the back surface side is set to be larger than the diameter of the binding warp on the front surface side.

摘要： According to the present invention, the curling or lifting of webs that occurs during the production nonwoven fabrics, and wrinkles that form on the surface of nonwoven fabrics are prevented. Also, the webs can be easily taken off without making grip stronger than necessary. The present invention pertains to an industrial fabric formed by weaving warp and weft, wherein an embossed pattern having a concavo-convex shape is formed in the vicinity of the apex of a knuckle portion exposed on the surface side of the warp and/or weft. In particular, the industrial fabric is characterized in that the warp and/or weft having the embossed pattern are plastic monofilaments.

摘要： A metal adsorbent which can adsorb a wide variety of metals, can conform to various uses, and adsorbs metals in large amounts . Metal adsorbents in various forms, which have the property of highly efficiently adsorbing metals, are produced by (a) a method in which a polyamine polymer is chemically bonded and immobilized to a porous support, (b) a method in which a polyamine polymer is blended into a solution of a raw material for fibers and the mixture is formed into fibers by wet-spinning or dry spinning, and (c) a method in which a polyamine polymer is blended into a solution of a film-forming polymer and the mixture is formed into a film by a method of film formation from solution.
