Abstract:
1. A method of manufacturing a polyethylene glycol treated fabric comprising: (a) exposing a fabric to a polyethylene glycol formulation including an acid catalyst and a resin to form a wet fabric; (b) heating and curing the wet fabric at a temperature such that the surface temperature of the wet fabric reaches a temperature sufficient to initiate a catalytic reaction for bonding the polyethylene glycol formulation to the fabric and in the heating and curing step the surface temperature does not exceed 220° F. to form a treated fabric; (c) neutralizing the treated fabric in a basic wash bath and forming a neutral fabric whereby the potential for reaction reversal and polymer washout is eliminated; and (d) drying the neutralized fabric.
