METHOD FOR PRODUCING POLYSACCHARIDE FIBER, POLYSACCHARIDE FIBER, CORD, FIBER-RUBBER COMPOSITE, AND TIRE

Document Type and Number:

Japanese Patent JP2013241702

Kind Code:

A

Abstract:

To provide a method for producing a polysaccharide fiber that is capable of suppressing carbon disulfide emission, has less environmental load, and is excellent in productivity, a polysaccharide fiber without fluffs and yarn breaks, a cord, a fiber-rubber composite, and a tire.

The method for producing a polysaccharide fiber 7 includes: contacting a polysaccharide solution obtained by dissolving a polysaccharide raw material in a liquid containing an ion solution with a solidifying liquid; spinning the polysaccharide; and winding the obtained polysaccharide fiber 7. The method is characterized by changing a traveling direction of the polysaccharide fiber 7 wound by using a guide or a roller 3 having a coefficient of dynamic friction of 0.05 to 0.35 to the polysaccharide fiber.
