COLOR MATCHING IN SPINNING AND DYEING OF ACRYLIC YARN

摘要

PURPOSE:To simply obtain spun and dyed yarn having the same color as that of piece dyeing in subjecting an acrylic polymer to wet spinning and coagulating to give gelatinous yarn, applying dye to the yarn, drawing, drying and heating and relaxing by using specific dye. CONSTITUTION:In obtaining spun and dyed yarn by subjecting an acrylic polymer to wet spinning, coagulating, applying dye to the gelatinous yarn, drawing, drying and heating and relaxing, dye having =1.5 color difference in Lab system after and before the heating and relaxing is used, the polymer is spun, conventionally colored and heat-treated under the same condition as that of the heating and relaxing to give a dyed material and the dye is prepared according to a recipe of the dyeing solution of the dyed material to simply carry out color matching in spinning and dyeing.
