Abstract
PURPOSE:To obtain the titled yarn absorbing an aqueous liquid even by bringing the yarn into contact with an aqueous solution such as underground water containing polyvalent ions, comprising an acrylonitrile polymer containing a specific amount of dissociated groups and the ratio of sulfonic group (salt) in the dissociated groups of >= a specific amount. CONSTITUTION:The aimed yarn comprising an acrylonitrile polymer containing 0.5-5mg equivalent/g dissociated groups and having >=20 equivalent sulfonic group or salt thereof in the dissociated groups. The polymer is preferably a copolymer of a monomer mixture consisting of (A) 70-98mol% acrylonitrile, (B) 2-30mol% sulfonic group-containing unsaturated monomer shown by the formula [R<1> is H or methyl; R<2> is 2-4C alkylene; X is -NH- or -0-; Y is H, alkaline (earth) metal or ammonium] and (C) 0-20wt.% other polymerizable monomers.
