Abstract
Abstract Shoes having dyed fabric uppers with elastomeric trimming bonded thereto are provided with an anti-color-migration coating on the portion of the fabric underlying the elastomeric trimming. The coating comprises a chlorinated rubber and a bleaching agent, such as sodium hypochlorite, and prevents discoloration of the elastomeric trimming due to migration of the dye from the fabric without adversely affecting the adhesion of the trimming to the fabric.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
76 words
In a shoe comprising a dyed fabric upper provided with elastomeric trimming bonded thereto, the improvement whereby discoloration of said elastomeric trimming due to migration of the dye from said fabric is prevented without adversely affecting the adhesion of said elastomeric trimming to said fabric, said improvement consisting of an anti-color-migration coating on the portion of said fabric underlying said elastomeric trimming, said anti-color-migration coating comprising a chlorinated rubber and a bleaching agent for said dye.
Claim 2
Dependent Claim
76 words
In a shoe comprising a dyed fabric upper provided with elastomeric trimming bonded thereto, the improvement whereby discoloration of said elastomeric trimming due to migration of the dye from said fabric is prevented without adversely affecting the adhesion of said elastomeric trimming to said fabric, said improvement consisting of an anti-color-migration coating on the portion of said fabric underlying said elastomeric trimming, said anti-color-migration coating comprising a chlorinated rubber and a bleaching agent for said dye.
Claim 3
Dependent Claim
15 words
The shoe in accordance with claim 1, wherein said chlorinated rubber is chlorinated natural rubber.
Claim 4
Dependent Claim
18 words
The shoe in accordance with claim 1, wherein said bleaching agent is an oxidizing agent for said dye.
Claim 5
Dependent Claim
14 words
The shoe in accordance with claim 1, wherein said bleaching agent is sodium hypochlorite.
Claim 6
Dependent Claim
18 words
The shoe in accordance with claim 1, wherein said fabric is a blend of polyester, nylon and cotton.
Claim 7
Dependent Claim
20 words
The shoe in accordance with claim 1, wherein said elastomeric trimming is of a lighter color than said dyed fabric.
Claim 8
Dependent Claim
29 words
The shoe in accordance with claim 1, wherein said anti-color-migration coating contains 80-150 parts by weight of said bleaching agent per 100 parts by weight of said chlorinated rubber.
Claim 9
Dependent Claim
111 words
In a method of manufacturing a shoe including the step of bonding elastomeric trimming to a dyed fabric upper, the improvement whereby discoloration of said elastomeric trimming due to migration of the dye from said fabric is prevented without adversely affecting the adhesion of said elastomeric trimming to said fabric, said improvement comprising the steps of applying onto the portion of said fabric which is to underlie said elastomeric trimming a coating composition comprising a chlorinated rubber, an organic solvent for said chlorinated rubber and a bleaching agent for said dye, evaporating the solvent from the coated fabric, and thereafter bonding said elastomeric trimming to the coated portion of said fabric.
Claim 10
Dependent Claim
111 words
In a method of manufacturing a shoe including the step of bonding elastomeric trimming to a dyed fabric upper, the improvement whereby discoloration of said elastomeric trimming due to migration of the dye from said fabric is prevented without adversely affecting the adhesion of said elastomeric trimming to said fabric, said improvement comprising the steps of applying onto the portion of said fabric which is to underlie said elastomeric trimming a coating composition comprising a chlorinated rubber, an organic solvent for said chlorinated rubber and a bleaching agent for said dye, evaporating the solvent from the coated fabric, and thereafter bonding said elastomeric trimming to the coated portion of said fabric.
Claim 11
Dependent Claim
15 words
The method in accordance with claim 8, wherein said chlorinated rubber is chlorinated natural rubber.
Claim 12
Dependent Claim
18 words
The method in accordance with claim 8, wherein said bleaching agent is an oxidizing agent for said dye.
Claim 13
Dependent Claim
14 words
The method in accordance with claim 8, wherein said bleaching agent is sodium hypochlorite.
Claim 14
Dependent Claim
13 words
The method in accordance with claim 8, wherein said organic solvent is toluol.
Claim 15
Dependent Claim
33 words
The method in accordance with claim 8, wherein said coating composition contains, by weight, 100-120 parts of said organic solvent, 10-15 parts of said chlorinated rubber, and 12-15 parts of said bleaching agent.
Claim 16
Dependent Claim
30 words
The method in accordance with claim 8, wherein the bonding of the elastomeric trimming to the fabric is effected through an adhesive applied to said coated portion of said fabric.
