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.
Claims14
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.
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.
