ABSTRACT:
A process for producing high tenacity and high modulus polyethylene fiber gel spinning. Cycloalkane and cycloalkene are selected as solvents for dissolving ultra-high molecular weight polyethylene, and a volatile solvent such as cyclohexanone or a mixture thereof is selected as an extracting solvent. The present process allows the extracted fibers to be stretched directly after the spinning step without requiring an intermediate winding step. The resulting fibers from the present invention have a tenacity greater than 15 g/d, a modulus greater than 350 g/d, an elongation at break less than 10%, and a crystallinity greater than 60%.
