METHOD FOR TREATING FABRIC WITH VISCOUS LIQUID POLYMERS

摘要

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 T9 in the range of about minus 40 to about 0°C and a zero shear melt viscosity of about 2 x 10^6 to about 1013 poise when measured at 2O°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.
