Abstract
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 The filament bundles are withdrawn from the spools and gathered into a tow which is cut by a fiber cutter to form the prefinished flock.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
66 words
The method of producing a flocked web comprising the steps of applying to a face of a porous fabric substrate an acrylic emulsion foam, at least partially drying and collapsing said foam to form a pervious subcoat, applying to said subcoat closely spaced dots of an adhesive in an unset state, applying flock to said adhesive carrying face and thereafter effecting the setting of said adhesive.
Claim 2
Independent Claim
66 words
The method of producing a flocked web comprising the steps of applying to a face of a porous fabric substrate an acrylic emulsion foam, at least partially drying and collapsing said foam to form a pervious subcoat, applying to said subcoat closely spaced dots of an adhesive in an unset state, applying flock to said adhesive carrying face and thereafter effecting the setting of said adhesive.
Claim 3
Dependent Claim
14 words
The method of claim 1 wherein said adhesive dots are applied by screen printing.
Claim 4
Dependent Claim
15 words
The method of claim 2 wherein said adhesive comprises an emulsion of a polymeric resin.
Claim 5
Dependent Claim
14 words
The method of claim 2 wherein said adhesive comprises a self-crosslinking acrylic polymeric resin.
Claim 6
Dependent Claim
33 words
The method of claim 4 wherein said adhesive and flock carrying web are exposed to a high frequency electric field to effect the heating of said adhesive and the crosslinking of said resin.
Claim 7
Dependent Claim
25 words
The method of claim 5 wherein said adhesive and flock carrying web is convection heated prior to said exposure to said high frequency electric field.
Claim 8
Independent Claim
78 words
The method of producing a flocked fabric comprising the steps of applying an acrylic resin emulsion foam precoat to said fabric, at least partially drying said precoat and squeezing said fabric to collapse said foam, applying a crosslinkable acrylic resin emulsion by screen printing in the form of closely spaced dots to said precoated fabric, applying a flock to said screen printed fabric, and thereafter effecting the drying of said emulsion and the crosslinking of said crosslinkable resin.
Claim 9
Independent Claim
78 words
The method of producing a flocked fabric comprising the steps of applying an acrylic resin emulsion foam precoat to said fabric, at least partially drying said precoat and squeezing said fabric to collapse said foam, applying a crosslinkable acrylic resin emulsion by screen printing in the form of closely spaced dots to said precoated fabric, applying a flock to said screen printed fabric, and thereafter effecting the drying of said emulsion and the crosslinking of said crosslinkable resin.
Claim 10
Dependent Claim
22 words
The method of claim 7 wherein said drying and crosslinking step includes exposing said flocked fabric to a high frequency electric field.
Claim 11
Dependent Claim
23 words
The method of claim 7 wherein said flocked fabric is exposed to a flock orienting electrostatic field during the application of said flock.
Claim 12
Dependent Claim
46 words
A flocked web comprising a porous cloth fabric substrate, a collapsed porous foam layer superimposed on and adherent to a face of said substrate, a plurality of closely spaced resin dots adherent to said foam layer, and flock fibers extending from and anchored to said dots.
Claim 13
Dependent Claim
46 words
A flocked web comprising a porous cloth fabric substrate, a collapsed porous foam layer superimposed on and adherent to a face of said substrate, a plurality of closely spaced resin dots adherent to said foam layer, and flock fibers extending from and anchored to said dots.
Claim 14
Dependent Claim
30 words
The web of claim 10 wherein said dots are formed of a crosslinked acrylic resin, and said fibers are oriented in a direction perpendicular to the plane of said web.
