  • Patent number: 3979538
    Abstract: A flocked fabric is produced by coating a knitted or woven fabric with an acrylic resin emulsion foam which is then partially dried and collapsed by squeezing. A self-cross-linking acrylic resin emulsion is screen printed as closely spaced dots on the coated fabric and polyester flock fibers having a flocking finish are deposited into the dot-carrying fabric while being oriented by an electrostatic field and the product is exposed to a hot air stream and high frequency dielectric field to dry and effect the cross-linking of the resin. The flock is produced by melt spinning pigment containing polyester and collecting them into bunches which are packaged on spools. The filament bundles are withdrawn from the spools and gathered into a tow which is cut by a fiber cutter to form the prefinished flock.
