Document Type and Number:
WIPO Patent Application WO/2022/107831
Kind Code:
A1
Abstract:
The present invention provides: a polyethylene fiber which exhibits high adhesiveness without impairing characteristics intrinsic to the fiber, namely, high strength, high elastic modulus and dimensional stability at high temperatures; and a method for producing this polyethylene fiber. According to the present invention, a highly adhesive polyethylene fiber which has high fiber mechanical characteristics, especially high initial elastic modulus that contradicts adhesiveness, is achieved by applying a functional agent to a polyethylene fibrous material in a state where a residual solvent is present and by performing a heat stretching process.
