Abstract

A knitted or woven component including an upper of an article of footwear, the upper including a knitted textile that is knitted together via a plurality of yarn such that the plurality of knitted yarn at least partially forms the knitted component. The article of footwear includes a midsole coupled to the knitted textile of the upper such that the midsole is positioned adjacent to the plurality of knitted yarn that at least partially forms the knitted component of the article of footwear, and an outsole coupled to the midsole on an opposite side of the knitted textile of the upper such that the outsole is separated from the plurality of knitted yarn that at least partially forms the knitted component of the article of footwear by the midsole disposed therebetween.

First claim

The invention claimed is:

1 . A knitted component, comprising:
an upper of an article of footwear, the upper including a knitted textile that is knitted together via a plurality of yarn such that the plurality of knitted yarn at least partially forms the knitted component, a non-fused region, a first fused region fused to a first degree, and a second fused region fused to a second degree that varies relative to the first degree, the first fused region is separated from the second fused region by the non-fused region; wherein the knitted textile includes a single layer having a first thickness at the first fused region based on the first degree of fusing, a second thickness at the second fused region based on the second degree of fusing, and a third thickness at non-fused regions, with the first thickness being relatively greater than the second thickness and less than the third thickness; and wherein the article of footwear includes:
a midsole coupled to the knitted textile of the upper such that the midsole is positioned adjacent to the plurality of knitted yarn that at least partially forms the knitted component of the article of footwear; and
an outsole coupled to the midsole on an opposite side of the knitted textile of the upper such that the outsole is separated from the plurality of knitted yarn that at least partially forms the knitted component of the article of footwear by the midsole disposed therebetween.

2 . The knitted component of claim 1 , wherein the single layer of the knitted textile of the upper is a continuous layer defined by the plurality of knitted yarn, and at least a portion of the knitted textile extends laterally outwards from the upper to form an edge between two adjacent portions of the continuous layer forming the knitted component, such that the edge extends laterally outwards in a z-direction from one of the adjacent portions of the continuous layer, wherein at least one of the adjacent portions has a thickness greater than the other portion, the thickness based on a degree of fusing.

3 . The knitted component of claim 1 , wherein each of the knitted textile of the upper, the midsole, and the outsole are formed of a thermoplastic polymer material such that substantially all of the knitted component and the article of footwear is formed of the thermoplastic polymer material; and
wherein the plurality of knitted yarn defining the knitted textile of the upper includes a first type of the thermoplastic polymer material, and each of the midsole and the outsole are formed of the first type of thermoplastic polymer material.

4 . The knitted component of claim 1 , wherein the upper includes the first fused region formed along a rear of the upper defined by the knitted textile such that the plurality of knitted yarn at the first fused region are at least partially fused together and the first thickness of the knitted textile at the first fused region is less than the third thickness of the non-fused regions of the knitted textile; and
wherein the upper includes the second fused region formed along a side of the upper below a plurality of lace apertures defined by the knitted textile such that the plurality of knitted yarn at the second fused region are fully fused together and the second thickness of the knitted textile at the second fused region is less than each of the first thickness of the first fused region and the third thickness of the non-fused regions of the knitted textile.

5 . An article of footwear comprising:
an upper comprising a textile, wherein the textile is a first component of a composite element defining the article of footwear, wherein the textile includes a single layer having an initial thickness at a non-fused region, a first fused region forming a heel counter with a first thickness that is less than the initial thickness, and a second fused region forming an indicia with a second thickness that is less than each of the initial thickness and the first thickness, wherein the non-fused region is disposed laterally between the first fused region and the second fused region; a midsole comprising a compressible foam, wherein the compressible foam is a second component of the composite element that is coupled to the first component; an outsole coupled to the compressible foam of the midsole; and wherein the textile, the compressible foam, and the outsole comprise a thermoplastic polymer material such that a majority of the article of footwear comprises the thermoplastic polymer material, and at least a portion of the thermoplastic polymer material is extracted from another article of footwear that is recycled.

6 . The article of footwear of claim 5 , wherein the textile is knitted together via a plurality of yarn such that the plurality of knitted yarn at least partially forms the upper.

7 . The article of footwear of claim 5 , wherein the second fused region is fused to a greater degree than the first fused region, thereby defining the second thickness less than the first thickness; and
wherein the first thickness and the second thickness are defined between an exterior surface of the single layer of the textile and an interior surface of the single layer of the textile.

8 . The article of footwear of claim 5 , wherein the midsole comprises a plate that is a third component of the composite element, the third component is coupled to the second component opposite from the first component.

9 . The article of footwear of claim 8 , wherein the first component of the composite element is thermally coupled to the second component of the composite element in response to an application of heat and/or pressure between interfacing surfaces of the first component and the second component; and
wherein the second component of the composite element is thermally coupled to the third component of the composite element in response to an application of heat and/or pressure between interfacing surfaces of the second component and the third component.

10 . The article of footwear of claim 8 , wherein the second component includes a longitudinal length that is substantially equal to a longitudinal length of the third component and a thickness that is greater than a thickness of the third component.

11 . The article of footwear of claim 5 , wherein the single layer of the textile is defined by a plurality of yarn and extends continuously across an entirety of the upper; and
wherein the textile includes an edge protruding laterally outwards between adjacent portions of the single layer of the textile, and the edge is defined by a portion of the plurality of yarn.

12 . The article of footwear of claim 5 , wherein the upper includes a plurality of lace apertures and an edge formed along the textile relatively below the plurality of lace apertures in response to fusing the textile adjacent to the plurality of lace apertures, such that the edge and the plurality of lace apertures are positioned radially outwards relative to non-fused regions of the textile that are positioned adjacent to the edge.

13 . The article of footwear of claim 5 , wherein the other article of footwear that is recycled includes at least ninety-five percent of a same thermoplastic polymer material by weight as the article of footwear.

14 . The article of footwear of claim 5 , wherein the thermoplastic polymer material comprises a thermoplastic polyamide or a thermoplastic polyurethane.

15 . The article of footwear of claim 5 , wherein the textile defines an ankle opening on the upper, and the textile includes a third fused region extending around the ankle opening; and
wherein the third fused
