Knit textiles and uppers, and processes for making the same
First Claim
1. A combination upper and outsole for an article of footwear, comprising:
- a textile including a first textile zone and a second textile zone, wherein the textile forms at least a medial midfoot area, a lateral midfoot area, and a ground-facing outsole area of the combination upper and outsole,wherein the first textile zone is rigid or semi-rigid and forms at least a portion of the ground-facing outsole area of the combination upper and outsole, and forms at least a portion of the ground-facing outsole area of an article of footwear when the combination upper and outsole is present in an article of footwear;
wherein the first textile zone includes a first re-flowed material, wherein the first re-flowed material is a melted and re-solidified product of a first yarn, and wherein the first re-flowed material comprises a low processing temperature polymeric composition, the low processing temperature polymeric composition comprising one or more first thermoplastic polymers; and
wherein the low processing temperature polymeric composition exhibits a melting temperature Tm that is 135°
C. or less;
wherein the second textile zone is flexible and/or pliable and forms at least a portion of the upper of the combination upper and outsole, and forms at least a portion of the upper of the article of footwear when the combination upper and outsole is present in an article of footwear; and
wherein the second textile zone includes a second yarn, the second yarn comprising a high processing temperature polymeric composition, the high processing temperature polymeric composition comprising one or more second thermoplastic polymers, wherein the high processing temperature polymeric composition exhibits at least one of;
1) a creep relaxation temperature Tcr;
2) a heat deflection temperature Thd;
or
3) a Vicat softening temperature Tvs that is greater than the melting temperature Tm of the low processing temperature polymeric composition,wherein the combination upper and outsole includes at least a portion of the second yarn in at least a first course of loops and a second course of loops, and at least a portion of the first re-flowed material connects at least a portion of the first course of loops with at least a portion of the second course of loops.

Abstract
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.
