Title:
ACRYLIC FIBER PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/098541
Kind Code:
A1
Abstract:
The present invention relates to an acrylic fiber production method by which a spinning dope obtained by dissolving an acrylic polymer in an organic solvent is wet-spun, wherein the acrylic polymer contains, with respect to the total mass of the acrylic polymer, 20-85 mass% of acrylonitrile, 14.5-79.5 mass% of vinyl chloride, and 0.5-10 mass% of a sulfonic acid group-containing monomer, the organic solvent is dimethyl sulfoxide, and the spinning dope contains 8-16 mass% of water with respect to the dry mass of the acrylic polymer. The present invention provides an acrylic fiber production method by which acrylic fibers that have favorable hackling properties can be obtained.
