POLYKETONE FIBER, METHOD OF PRODUCING THE SAME AND POLYKETONE TWISTED YARN

Title:

POLYKETONE FIBER, METHOD OF PRODUCING THE SAME AND POLYKETONE TWISTED YARN

Document Type and Number:

Japanese Patent JP3708030

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a polyketone fiber having excellent mechanical properties such as high strength, high elastic modulus, together with free from agglutination of single yarns, low in coefficient of dynamic friction between fiber-fiber, homogeneous and low in defects, having an excellent utilization factor of twisted yarn strength, expressing high strength after twisting and excellent in fatigue resistance, and twisted yarn of the fiber is expected to have a wide range of applications as a high strength industrial material, especially useful as a reinforcing material for rubber, FRP or the like.
SOLUTION: This polyketone fiber is made of a polyketone comprising 1- oxotrimethylene composing 95 to 100 wt.% of repeating units and possesses properties meeting the following (a) to (e): (a) a degree of crystallization ≥60%; (b) a degree of crystalline orientation ≥90%; (c) tensile strength ≥10 cN/dtex; (d); rate of agglutination of single yarn ≤30%, (e); deposit efficiency of finishing materials = 0.3 to 15 wt.%.
