Thermoplastic non-woven textile elements
First Claim
1. A method of manufacturing a composite element incorporated in an article of apparel, the method comprising:
- locating a component adjacent to a surface of a non-woven textile formed from a plurality of filaments that include a thermoplastic polymer material, wherein the component is in contact with at least a portion of the plurality of filaments, wherein the component includes a woven textile that is formed of a plurality of yarns, the plurality of yarns being mechanically manipulated to exhibit a one-directional stretch which allows the woven textile to stretch in a first direction but limits stretch of the woven textile in a direction perpendicular to the first direction;
melting at least a first portion of the plurality of filaments of the non-woven textile such that the at least first portion of the plurality of filaments exhibits a non-filamentous configuration, wherein the non-filamentous configuration has no permeability to gaseous and liquid fluids;
heating and compressing the component and the non-woven textile to bond the component to the non-woven textile, wherein the component includes a thickness that is comparable to the thickness of the non-woven textile therebysecuring the component to the non-woven textile by a heatbonding process;
forming a composite element, wherein the at least first portion of the plurality of filaments is in contact with the component, wherein the non-filamentous configuration of the at least first portion of the plurality of filaments increases the stretch-resistance of the composite element; and
incorporating the component and the non-woven textile into the article of apparel.

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.

8. A method of manufacturing a composite element incorporated in an article of apparel, the method comprising:
-
locating two layers of a non-woven textile on opposite sides of an intermediate element, the layers being formed from a plurality of filaments that include a thermoplastic polymer material, the intermediate element including a solid sheet of polymer material; forming at least a first fused region in at least one layer of the non-woven textile, wherein the at least first fused region exhibits a non-filamentous configuration, wherein the non-filamentous configuration has no permeability to gaseous and liquid fluids; heating and compressing the layers and the intermediate element to heatbond the layers to the opposite sides of the intermediate element, wherein at least a portion of the plurality of filaments of the layers that exhibit the non-filamentous configuration are in contact with the intermediate element, wherein the at least first fused region increases the stretch-resistance of the composite element; heatbonding the two layers directly to each other around at least a portion of a perimeter of the intermediate element; securing the intermediate element to the layers, wherein the thermoplastic polymer material of the layers is used to directly secure the layers to the intermediate element without the use of additional adhesives; and incorporating the intermediate element and the non-woven textile into the article of apparel. - View Dependent Claims (9, 10, 11, 12, 20)

13. A method of manufacturing a composite element incorporated in an article of apparel, the method comprising:
-
locating a series of substantially parallel strips adjacent to a surface of a non-woven textile formed from a plurality of filaments that include a permeable thermoplastic polymer material, the strips including solid sheets of polymer material; melting at least a portion of the plurality of filaments of the non-woven textile to form at least one fused region, the at least one fused region exhibiting a non-filamentous configuration, wherein the non-filamentous configuration has no permeability to gaseous and liquid fluids, wherein the non-filamentous configuration of the at least one fused region increases the stretch-resistance of the non-woven textile; disposing the strips along the surface of the non-woven textile such that adjacent strips are spaced apart from one another; heating and compressing the strips and the non-woven textile to heatbond the strips to the non-woven textile, wherein at least a portion of the plurality of filaments of the non-woven textile that exhibit the non-filamentous configuration are in contact with the strips, such that the at least one fused region increases the stretch-resistance of the composite element; securing the strips to the non-woven textile, wherein the thermoplastic polymer material of the non-woven is used to directly secure the first textile element to the strips without the use of additional adhesives; forming regions of no permeability in the composite element associated with the areas where the non-woven textile is bonded to the strips, while the interstitial spaces remain relatively permeable; and incorporating the strips and the non-woven textile into the article of apparel. - View Dependent Claims (14, 15, 16, 17, 21)
