Abstract

PURPOSE: To obtain the title fiber having water resistance in one process without lowering spinning efficiency, by using a raw material prepared by introducing acetoacetic estergroups into a PVA based resin and simultaneously adding a crosslinking agent into a spinning bath.
CONSTITUTION: An aqueous solution of an acetoacetic ester group-containing PVA based resin (hereinafter referred to as AA group-containing PVA based resin) is spun into a spinning bath containing a crosslinking agent (e.g., formaldehyde or phenol) to provide the aimed fiber. Further, e.g., a resin obtained by an addition reaction of PVA having 80W100mol% average saponification degree and 500W2000 average polymerization degree with diketene is preferably used as the AA group-containing PVA based resin. Furthermore, the content of the crosslinking agent in the spinning solution is preferably 5W50g/l. In addition, the spinning is preferably carried out by normally discharging the spinning solution at 80W90°C through a nozzle into the spinning bath at 10W40°C.
