Abstract
Abstract The cut edge of a fabric is preheated to a temperature which will cause an increase in viscosity of a subsequently applied heat-solidifiable composition and reduce its migration into the fabric. The composition is applied to the preheated edge and further heated to solidification.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
31 words
A method as defined in claim 1 wherein said cut edge is preheated to a temperature sufficient to initiate gelatin of the film-forming composition on the edge during the coating step.
Claim 2
Dependent Claim
32 words
A method as defined in claim 1 wherein the film-forming composition is a polyvinyl chloride plastisol composition and wherein the cut edge is preheated to a temperature of at least 150* F.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein said film forming composition is a plastisol.
Claim 4
Dependent Claim
11 words
The method of claim 4 wherein said plastisol is polyvinyl chloride.
Claim 5
Independent Claim
116 words
A method for reducing the roughness of the cut end of a fill yarn of a woven fabric having a cotton warp and a nylon fill by the application of a liquid heat-solidifiable, film-forming composition comprising the steps of a. supplying a woven fabric having a cut nylon fill edge, b. preheating the cut edge of the fabric to a temperature sufficient to cause an increase in the viscosity of a subsequently applied heat-solidifiable, film-forming composition to reduce its tendency to migrate into the inner portions of the fabric, c. coating the heated edge of the fabric with a heat-solidifiable, film-forming composition, and d. heating the coated edge of the fabric to solidify the composition thereon.
Claim 6
Dependent Claim
39 words
A method as defined in claim 6 wherein said fabric has a second cut nylon fill edge, and said second edge is preheated, coated with a heat-solidifiable film-forming composition, and the coated edge heated to solidify the composition thereon.
Claim 7
Dependent Claim
19 words
The method of claim 7 wherein said cut edges are preheated to a temperature of at least 150* F.
Claim 8
Dependent Claim
13 words
The method of claim 8 wherein said film forming composition is a plastisol.
Claim 9
Dependent Claim
12 words
The method of claim 9 wherein said plastisol is a polyvinyl chloride.
