BONDING TO POLYOLEFIN TEXTILES AND UPPERS AND ARTICLES OF FOOTWEAR FORMED THEREFROM

Abstract:

Methods of bonding components are provided that provide for improved bonding when one or both of the components include a textile component including a polyolefin resin. Articles of footwear, athletic apparel, sporting equipment, and portions thereof are also provided including the components, at least one of which includes a polyolefin textile component, and the component are adhesively bonded together by methods and/or compositions described herein. Methods can include (i) applying a chlorinated polyolefin primer to a surface of the textile component to produce a primed surface; (ii) applying a first waterborne polyurethane adhesive to the primed surface to produce an adhesive surface; and (iv) contacting a surface of the second component to the adhesive surface to adhesively bond the second component to the textile component. In some aspects, the textile component is an upper including an adhesive bond to a sole component such as a plate.
