Textiles and articles, and processes for making the same
Articles of wear having one or more textiles that include a low processing temperature polymeric composition and a high processing temperature polymeric composition, and methods of manufacturing the same are disclosed. The low processing temperature polymeric composition and the high processing temperature polymeric composition can be selectively incorporated into a textile to provide one or more structural properties and/or other advantageous properties to the article. The textile can be thermoformed to impart such structural and/or other advantageous properties to the article of wear. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
