AROMATIC POLYAMIDE FIBER FOR RUBBER REINFORCEMENT, AROMATIC POLYAMIDE FIBER TWISTED CORD AND FIBER REINFORCED RUBBER COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a fiber cord for rubber reinforcement to which an RFL treatment agent can be adhered uniformly without complex treatment and which has stable quality without fray of a twisted cord and an aromatic polyamide fiber in a process for manufacturing the fiber cord for rubber reinforcement.SOLUTION: There is provided an aromatic polyamide fiber for rubber reinforcement having practically no pray by adding a treatment agent containing resorcin formalin rubber latex (RFL) with a status with holding moisture percentage of 25 to 70 mass% with an aromatic polyamide fiber composite having no hysteresis of drying with the moisture percentage of less than 25 mass%, where an adhesive is impregnated into a fiber skeleton.SELECTED DRAWING: None
