Abstract
Abstract A process for making a porous flocked fabric by coating one side of a loosely interlaced substrate with a flock binder. The coated side of the substrate is flocked and the binder is allowed to migrate or strike through to the opposite side of the substrate. A particulate material, e.g., flock, ground flock, talc, etc., is then applied to said opposite side by means of an auxiliary substrate and the binder is permanently set by curing.

A PROCESS FOR MAKING A POROUS AIR PERMEABLE FABRIC WHICH COMPRISES: A. PLACING A LOOSELY INTERLACED SUBSTRATE ON AN AUXILIARY SUBSTRATE ON WHICH FLOCK FIBERS HAVE BEEN TEMPORARILY AND REMOVABLY DEPOSITED TO COVER SUBSTANTIALLY THE ENTIRE SURFACE OF THE AUXILIARY SUBSTRATE, B. COATING SUBSTANTIALLY THE ENTIRE SIDE OF THE INTERLACED SUBSTRATE WHICH FACES AWAY FROM THE AUXIALIARY SUBSTRATE WITH AN ADHESIVE BINDER, C. DISTRIBUTING FLOCK FIBERS OVER SUBSTANTIALLY THE ENTIRE SURFACE OF THE COATING, D. ALLOWING THE COATING TO STRIKE-THROUGH THE INTERLACED SUBSTRATE SUFFICIENTLY TO SECURE THE FLOCK FIBERS ON SAID AUXILIARY SUBSTRATE TO THE SIDE OF THE INTERLACED SUBSTRATE OPPOSITE THE COATED SIDE, E. PERMANENTLY SETTING THE BINDER, AND F. SEPARATING THE FLOCKED SUBSTRATE AND THE AUXILIARY SUBSTRATE FROM EACH OTHER.
