RAISED PRODUCT AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a raised product having an excellent touch feeling by a method for producing the raised product comprising using acrylic staple fibers dyed with a cationic dye, carrying out a dry heat polisher step and processing the acrylic staple fibers into piles. SOLUTION: This raised product is obtained by using an acrylic polymer containing 0.5-5 wt.% of a sulfonate group-containing monomer as a raw material, wet spinning the polymer, then dyeing the resultant staple fibers with the cationic dye in a hot bath at <95 deg.C and regulating both the ratio of Young's modulus of the acrylic staple fibers to the Young's modulus of undyed acrylic staple fibers (RW staple fibers) and the ratio of boiling water shrinkage percentage of the acrylic staple fibers to the boiling water shrinkage percentage of the RW staple fibers within the range of 0.07-1.50, carrying out the dry heat polisher step and processing the acrylic staple fibers into the piles. The method for producing the raised product is provided.
