Abstract
Abstract A flocked polyurethane foam fabric and method for manufacturing the same for which flock fibers imbedded in an adhesive on the foam are permanently flattened and entangled. Dry ink is transferred onto the flock fibers at the same time that flattening of the fibers is taking place. The flock fibers are thermally set into their flattened state along an outer surface of a polyurethane foam base of the fabric. Flattening the flock fibers causes the entanglement of the flock, thereby improving the hand, appearance, drapeability, abrasion resistance, water repellency and heat insulation qualities for apparel items over that of unflattened flock fibers.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
77 words
A flocked foam fabric, comprising: a foamed polyurethane element having an outer surface; flock fibers; and means for adhering the flock fibers onto said outer surface, said flock fibers having an end imbedded into said adhering means and a portion projecting out of said adhering means, said portion being thermally set into a flattened and entangled state along said outer surface of said foamed element so as to provide a substantially flat surface with entangled flock fibers.
Claim 2
Dependent Claim
77 words
A flocked foam fabric, comprising: a foamed polyurethane element having an outer surface; flock fibers; and means for adhering the flock fibers onto said outer surface, said flock fibers having an end imbedded into said adhering means and a portion projecting out of said adhering means, said portion being thermally set into a flattened and entangled state along said outer surface of said foamed element so as to provide a substantially flat surface with entangled flock fibers.
Claim 3
Dependent Claim
12 words
The fabric according to claim 1, wherein said flock fibers are synthetic.
Claim 4
Dependent Claim
13 words
The fabric according to claim 2, wherein said fibers are composed of nylon.
Claim 5
Dependent Claim
22 words
The fabric according to claim 1, further comprising: ink of a solid color on said fibers in said flattened and entangled state.
Claim 6
Dependent Claim
32 words
The fabric according to claim 4, further comprising: a plurality of dissimilar colored inks each selectively applied to selective areas of said flock in said flattened state to form a multi-colored pattern.
Claim 7
Dependent Claim
15 words
The fabric according to claim 1, wherein said adhering means is a latex acrylic adhesive.
Claim 8
Dependent Claim
66 words
The fabric according to claim 1, wherein said flock fibers in said flattened and entangled state provide greater cover on said foamed polyurethane element than said flock fibers standing upright in an unflattened state so as to provide, better water repellency, better drapeability, better abrasion resistance, more heat insulation and greater resistance to being pulled out than does said fibers standing upright in the unflattened state.
Claim 9
Dependent Claim
27 words
The fabric according to claim 1, wherein said portion is thermally set so that even after repeated washing said portion remains in a flattened and entangled state.
Claim 10
Dependent Claim
22 words
The fabric according to claim 1, further comprising: two ends of filament in a raschel knit fabric against the foamed polyurethane element.
Claim 11
Independent Claim
84 words
A method of making a flattened flock foam fabric, comprising the steps of: flattening and entangling a portion of flock fibers of a flocked polyurethane foam fabric, each of the fibers having an end imbedded in an adhesive on a foamed polyurethane element of the flocked polyurethane foam fabric so that said flock fibers are in a flattened and entangled state along an outer surface of the foamed polyurethane element; and thermally setting said portion of flock fibers in the flattened and entangled state.
Claim 12
Independent Claim
84 words
A method of making a flattened flock foam fabric, comprising the steps of: flattening and entangling a portion of flock fibers of a flocked polyurethane foam fabric, each of the fibers having an end imbedded in an adhesive on a foamed polyurethane element of the flocked polyurethane foam fabric so that said flock fibers are in a flattened and entangled state along an outer surface of the foamed polyurethane element; and thermally setting said portion of flock fibers in the flattened and entangled state.
Claim 13
Dependent Claim
20 words
A method according to claim 10, further comprising the step of: transferring ink onto the flattened and entangled flock fibers.
Claim 14
Dependent Claim
24 words
A method according to claim 11, wherein said transferring includes transferring dry ink from a paper sheet onto the flattened and entangled flock fibers.
Claim 15
Dependent Claim
20 words
A method according to claim 11, wherein the steps of flattening and entangling, thermally setting and transferring take place simultaneously.
Claim 16
Dependent Claim
61 words
A method according to claim 10, wherein the step of flattening and entangling includes feeding the flocked polyurethane foam fabric between pressure elements which apply pressure for flattening the flock fibers, the step of thermally setting including heating at least one of the pressure elements to a predetermined temperature to thereby cause the fibers to thermally set in the flattened state.
Claim 17
Dependent Claim
97 words
A method according to claim 10, wherein the step of flattening and entangling includes feeding together both the flocked polyurethane foam fabric and a thermal sheet between pressure elements which apply pressure for flattening the flock fibers, the sheet having dry ink on a side that is against the flock fibers, the step of thermally setting including heating at least one of the pressure elements to a predetermined temperature so as to cause the flock fibers to thermally set in the flattened and entangled state and to cause the dry ink to transfer onto the flock fibers.
Claim 18
Dependent Claim
39 words
A method according to claim 15, further comprising: dyeing the polyurethane foam fabric with a solid color before adhering the flock fibers to the polyurethane foam fabric, the dry ink including at least one ink of said solid color.
Claim 19
Dependent Claim
27 words
A method according to claim 15, wherein the adhesive has a solid color and the dry ink has at least one ink of the same solid color.
Claim 20
Dependent Claim
22 words
A method according to claim 10, further comprising: forming an apparel item with the flattened and thermally set flocked polyurethane foam fabric.
Claim 21
Dependent Claim
14 words
A method according to claim 10, further comprising: dyeing the flocked polyurethane foam fabric.
