Abstract

PURPOSE: To obtain synthetic rushes having suitable water absorption, comfortable touch, and improved color fastness, by extruding an acrylic polymer melt prepared in the presence of water containing a dye at 120°C or above into a low-pressure zone.
CONSTITUTION: A melt is prepared by kneading 30W90 wt.% of an acrylic polymer consisting solely or mainly of acrylonitrile and 1W56 wt.% of water containing a dye, and, if necessary, 2W63 wt.% of acrylonitrile at 120°C or above, or by polymerizing a mixture of monomers consisting mainly of acrylonitrile and 10W30 wt.% of water containing a dye at 120°C or above under pressure, and then extruded through an orifice into a low-pressure zone to form filamentary foams.
