Effect of Non-Equilibrium Low Temperature Plasma on Genuine Leather Adhesion Properties of Special Purpose Footwear Upper to Molding Compositions with Polyurethanes Base

Abstract:

Roughing operation is used to improve the adhesive properties of footwear upper to footwear bottom polyurethane compositions in the manufacture of special purpose footwear with an upper made of genuine leather by the injection molding method of attachment. Roughing operation is an operation of coating removal and partial removal of the front layer from the protracted edge of footwear upper workpiece. This operation has a disadvantage, it often causes technological defects. A method for increasing the adhesive properties of genuine leather special purpose footwear upper workpiece with a front layer by means of non-equilibrium low temperature plasma modification and technological scheme that allows this operation to be integrated into the production process are considered in the article.
