ARAMID SHORT FIBER BUNDLE FOR RUBBER REINFORCEMENT

摘要

To provide an aramid short fiber bundle for rubber reinforcement, in which the adhesion of a resorcin/formalin/rubber latex (RFL) to the surface of the bundle made of aramid short fibers is good, and by remaining on the fiber surface after rubber kneading, the adhesion with rubber is maintained, and by having a sufficient affinity with rubber, the dispersibility in rubber becomes good.SOLUTION: Provided is an aramid short fiber bundle for rubber reinforcement in which a resorcin/formalin/rubber latex mixed with a polyether ester-based compound having a solubility parameter (SP value) in the range of 8.5 to 9.5 is adhered on the surface of a bundle made of aramid short fibers.SELECTED DRAWING: None
