HOT-MELT TYPE ADHESIVE FIBER

摘要

PURPOSE:To obtain the title fiber highly adhesive to fibrous structures and capable of giving flexible fibrous structures by blending a specified proportion of a polyolefin resin with a polymer prepared by hydrogenation of conjugated diene (co)polymer followed by addition of unsaturated carboxylic acid. CONSTITUTION:The objective adhesive fiber can be obtained by applying on at least part of its surface a resin composition prepared by blending (A) a polyolefin resin with (B) a polymer produced by adding 1.0-15 pts.wt. of an unsaturated carboxylic acid such as maleic anhydride or citraconic acid or its derivative to 100 pts.wt. of a hydrogenated product formed by hydrogenating >=50% of the main chain C=C bond in a conjugated diene (co)polymer 8000-200000 in molecular weight such as isoprene polymer or isoprene/butadiene copolymer, at the weight ratio A/B=(98-70):(2-30).
