ABSTRACT:
The impregnation of a non-woven fabric with a plastisol is accomplished by first coating the fabric with a heated plastisol having a viscosity in the range of 4 to 30 poise, subsequently pressing the coated fabric against a rotating cylinder which has been heated to within the range of 130.degree. to 180.degree. C. and maintaining the coated fabric in contact with the cylinder for a sufficient time to obtain complete impregnation of the fabric by the plastisol and to gel the plastisol to the side of the fabric disposed away from the cylinder.
