Abstract

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.
