发明名称 PRODUCTION OF ACRYLIC PRECURSOR YARN FOR CARBON FIBER
摘要 PURPOSE:To obtain the subject yarn giving high quality fiber with preventing mutual fusion among single fibers by spinning an acrylic polymer solution and subjecting the resultant wet yarn to a multi-bath drawing in water of a specific temperature in at least two separated drawing baths installing free rollers between the baths. CONSTITUTION:A solution of acrylic polymer containing >=90wt.% acrylonitrile is spun and the resultant wet yarn is drawn in passing through at least two separated drawing baths installing free rollers between the baths and filled with water of 40-98 deg.C temperature (preferably, 30-50 deg.C for >=1% residual solvent in the yarn and 40-98 deg.C for <=1% residual solvent) and the resultant drawn yarn is supplied of 0.1-3wt.% amino-modified polysiloxane-containing oil by spraying, etc., to afford the objective yarn.
