Abstract
A process of treating a woven fabric by applying to the fabric a viscous polymer in a 5 to 40 wt % solution with a solvent, wherein the polymer has a Tg in the range of about minus 40 to about 0° C. and a zero shear melt viscosity of about 2×106 to about 1013 poise when measured at 20° C. and then evaporating the solvent such that the polymer only partially penetrates the fabric and penetrates to in and between fiber bundles before the polymer solidifies.
