Abstract

PURPOSE:To obtain in high productivity the titled yarn with high strength and high initial modulus, also free from mutual fiber sticking, by dry-wet spinning of a stock solution prepared by dissolving PVA in a mixed solvent made up of dimethylsulfoxide and water, followed by applying specific treatment. CONSTITUTION:First, PVA is dissolved in a solvent consisting mainly of a mixture of dimethylsulfoxide and water to prepare a spinning stock solution followed by dry-wet spinning of this stock solution to form (undrawn) yarn. Thence, the residual solvent in said yarn is extracted with either a mixture of alcohol (pref. methanol) and water or another mixture of ketone (pref. acetone) and water to obtain a water-contg. yarn. This yarn is subsequently wet- drawn by a factor of 3-8 followed by dry heat drawing, thus obtaining the objective yarn. The water content in said water-contg. yarn is pref. 0.2-20wt.%.
