ABSTRACT:
A high strength and high initial modulus polyvinyl alcohol monofilament yarn and a process for producing the same with high productivity are disclosed, the monofilament yarn comprising polyvinyl alcohol having a polymerization degree of from 1500 to 7000, having a tensile strength of not less than 10 g/d and an initial modulus of not less than 200 g/d, and having a fineness of 100 denier or more; and the process comprising dry-wet spinning a spinning dope prepared by dissolving polyvinyl alcohol having a polymerization degree of from 1500 to 7000 in a solvent and stretching the resulting unstretched filament, wherein a plurality of filaments immediately after being spun from a spinning nozzle having a plurality of orifices are closely adhered and united into a substantially single strand in an inert atmosphere and then introduced into a coagulating bath or a cooling bath.
