Flexible reinforced hose and method of making the same

Abstract

A flexible reinforced hose comprising nylon tubing to which a reinforcement (braid or spiral wrapping) of a synthetic or natural fiber is bonded, said tubing having an outer surface plasticized with meta-cresol to which said reinforcement is applied. Prior to application of the reinforcement excess meta-cresol is wiped off from the tubing whereby minimal residual meta-cresol remains in the completed hose. In the case of reinforcing fiber other than nylon, the bond between the reinforcing layer and the nylon tubing is essentially a mechanical bond whereas in the case of nylon reinforcing fiber, the inner surface of the reinforcement is fusion bonded to the outer surface of the tubing. In the method of making the hose herein, nylon tubing passes through a heated meta-cresol bath with excess meta-cresol being wiped off the tubing prior to application for a reinforcement of synthetic or natural fiber on the plasticized outer surface of the tubing containing minimal residual meta-cresol.
