<P>PROBLEM TO BE SOLVED: To provide a polyamide monofilament which can be preferably used as a constituent material for industrial woven fabrics by improving antifouling performance of the polyamide monofilament comprising only a biomass-derived polymeric material that is obtained from non-fossil resources, achieving excellent accuracy in fiber diameter and necessary and sufficient strength properties, and realizing the polyamide monofilament excellent in water absorption dimension stability, and to provide an industrial woven fabric using the same. <P>SOLUTION: A polyamide monofilament comprises a polyamide resin composition including: 98 to 85 wt% of a polyamide resin produced by polycondensation of an aliphatic diamine containing 1,5-diaminopentane as a main component and a dicarboxylic acid containing a sebacic acid as a main component; and 2 to 15 wt% of a carnauba wax. In the polyamide monofilament, a gum pitch antifouling index calculated from a peeling stress value for a cloth adhesive gum tape by the following expression (1): Gum pitch antifouling index=peeling stress for a test sample/peeling stress for a reference sample×100 is 90 or less, and tensile breaking strength is 3.0 cN/dtex or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
