Abstract

PURPOSE: To obtain the titled filament having improved adhesiveness to a cement base material, by drawing and heat-treating under specific conditions a filmanet which is obtained from an aqueous solution of polyvinyl alcohol by set spinning or dry spinning.
CONSTITUTION: An aqueous solution of polyvinyl alcohol is spun by wet spinning or dry spinning to give a filament, which is drawn and heat-treated conventionally, to give a polyvinyl alcohol type filament. In the operation, the total draw radio is made not less than ten times, after dry heat drawing the filament is provided with a contraction 0W3% and heat-treated at a temperature 2°C or more lower than the temperature to dry heat drawing, to give a polyvinyl alcohol type filament having a strength not less than 90kg/mm2, a Young's modulus not less than 1,700kg/mm2, and a dissolved amount for 30min not less than 10% when it is boiled in boiling water in the form of 3W10mm long pieces. Having high hydrophylic nature, and increased affinity to cement, and strength and Young's modulus are maintained at high value.
