AI summary

The present disclosure provides for composite textiles that can include a coating layer that is compatible with textiles such as those comprising polyolefins. The coating layer, as well as the precursor coating layer composition, the coating mixture, or resin composition used to form the coating layer, include a mixture of a polyolefin resin and a thermoplastic vulcanizate (TPV). It is believed that the use of the coating layer in the disclosed composite textiles can promote better bonding between other components or materials used in articles, such as articles of footwear or articles of clothing, while resisting or preventing creasing and bagging. This allows the use of cost-effective materials such as polyolefins in the composite textiles that have adequate physical and mechanical properties, while also having sufficient chemical bonding properties.
