摘要： PROBLEM TO BE SOLVED: To provide a water-soluble PVA-based fiber having fiber performances such as practically sufficient mechanical properties and chemical resistance without impairing a conventional water-soluble property and extremely useful for nonwoven fabrics including a base fabric for chemical lace and many applications including spun yarn and to provide a method for producing the fiber.
SOLUTION: In the water-soluble PVA-based fiber, a compound having an ionic group is reacted in a ratio of 0.01-5 mol% and the relationship between a degree (Xc/%) of crystallization of the fiber and a water-fusing temperature (Wtb/°C) of the fiber satisfies the formula: Wtb

摘要： PROBLEM TO BE SOLVED: To stably obtain a polyvinyl alcohol-based spun raw fiber capable of being drawn in high efficiency and at a high speed, by a high speed spinning method using a simple installation. SOLUTION: This polyvinyl alcohol-based spun raw fiber is produced by extruding the organic solvent-based spinning raw liquid of the polyvinyl alcohol- based polymer from a nozzle, solidifying the extruded product, relaxing and shrinking the obtained solid fiber, and then guiding the fiber to the first godet roller through a washing bath. Therein, the liquid surface area of the washing tank is five times or more the cross-sectional area of a solidifying liquid inlet.

摘要： PROBLEM TO BE SOLVED: To obtain polyvinyl alcohol-based spun raw fibers capable of being drawn in high efficiency and at a high speed by a high speed spinning method with a simple installation. SOLUTION: This method for producing the polyvinyl alcohol-based fibers comprises extruding the organic solvent-based spinning stock solution of the polyvinyl alcohol-based polymer from a nozzle, solidifying the extruded fibers, guiding the solidified fibers to the first godet roller, bringing the obtained solidified sliver into contact with an extraction bath having a higher solidifying solvent concentration than that of the solidification bath, simultaneously continuously shrinking the fibers with a tapered roller, wet-drawing the fibers, drying the fibers, and then subjecting the fibers to a dry heat drawing treatment.
