Abstract

A warp knit component that includes a first front weft inlaid yarn that extends through one or more loops in a first warp knit course, and after extending through the one or more loops, the first front weft inlaid yarn extends as a float positioned on a technical face or front side of the warp knit component. After extending as the float, the first front weft inlaid yarn extends through one or more loops in a second warp knit course that is offset in the material flow direction from the first warp knit course. Using floats facilitates the advancement of the first front weft inlaid yarn in the material flow direction.

First claim

What is claimed is:

1 . A warp knit component, comprising:
a plurality of warp knit courses that form a plurality of warp knit wales; and a first front weft inlaid yarn, wherein:
the first front weft inlaid yarn extends through at least one loop in a first warp knit course of the plurality of warp knit courses,
after extending through the at least one loop in the first warp knit course, the first front weft inlaid yarn extends as a float positioned on a technical face of the warp knit component, and
after extending as the float, the first front weft inlaid yarn extends through at least one loop in a second warp knit course of the plurality of warp knit courses, the second warp knit course offset in a material flow direction from the first warp knit course.

2 . The warp knit component of claim 1 , further comprising a second front weft inlaid yarn, wherein:
the second front weft inlaid yarn extends through at least one loop in a third warp knit course of the plurality of warp knit courses, after extending through the at least one loop in the third warp knit course, the second front weft inlaid yarn extends as a float positioned on the technical face of the warp knit component, and after extending as the float, the second front weft inlaid yarn extends through at least one loop in a fourth warp knit course.

3 . The warp knit component of claim 2 , wherein at least one of the first warp knit course and the second warp knit course is offset from at least one of the third warp knit course and the fourth warp knit course in a wale-wise direction.

4 . The warp knit component of claim 2 , wherein the first front weft inlaid yarn is positioned on a first side of a hypothetical midline that extends in a material flow direction of the warp knit component, and wherein the second front weft inlaid yarn is positioned on a second side of the hypothetical midline.

5 . The warp knit component of claim 2 , wherein the first front weft inlaid yarn is one or more of a different yarn type and a different denier than the second front weft inlaid yarn.

6 . The warp knit component of claim 1 , further comprising a first back weft inlaid yarn that extends through every successive loop in the first warp knit course and a second back weft inlaid yarn that extends through every successive loop in the second warp knit course, the first back weft inlaid yarn and the second back weft inlaid yarn positioned closer to a technical back of the warp knit component as compared to the first front weft inlaid yarn.

7 . The warp knit component of claim 6 , further comprising one more intervening warp knit courses between the first warp knit course and the second warp knit course.

8 . The warp knit component of claim 7 , further comprising one or more additional back weft inlaid yarns that extend through every successive loop in the one or more intervening warp knit courses.

9 . An integrally warp knit upper having a medial side and a lateral side, the integrally warp knit upper comprising:
a plurality of warp knit courses that extend from the medial side to the lateral side of the upper; and a first front weft inlaid yarn positioned on the lateral side of the upper, wherein:
the first front weft inlaid yarn extends through at least one loop in a first warp knit course of the plurality of warp knit courses,
after extending through the at least one loop in the first warp knit course, the first front weft inlaid yarn extends as a float positioned on an outer-facing surface of the integrally warp knit upper, and
after extending as the float, the first front weft inlaid yarn extends through at least one loop in a second warp knit course of the plurality of warp knit courses, the second warp knit course offset in a material flow direction from the first warp knit course.

10 . The integrally warp knit upper of claim 9 , further comprising a second front weft inlaid yarn positioned on the medial side of the upper, wherein:
the second front weft inlaid yarn extends through at least one loop in a third warp knit course of the plurality of warp knit courses, after extending through the at least one loop in the third warp knit course, the second front weft inlaid yarn extends as a float positioned on the outer-facing surface of the integrally warp knit upper, and after extending as the float, the second front weft inlaid yarn extends through at least one loop in a fourth warp knit course.

11 . The integrally warp knit upper of claim 10 , wherein the first front weft inlaid yarn is one or more of a different yarn type and a different denier than the second front weft inlaid yarn.

12 . The integrally warp knit upper of claim 10 , wherein the first front weft inlaid yarn forms a first geometric pattern on the lateral side of the upper, wherein the second front weft inlaid yarn forms a second geometric pattern on the medial side of the upper, and wherein the first geometric pattern comprises a different geometric pattern than the second geometric pattern.

13 . The integrally warp knit upper of claim 10 , wherein at least one of the first warp knit course and the second warp knit course is offset from at least one of the third warp knit course and the fourth warp knit course in a wale-wise direction.

14 . The integrally warp knit upper of claim 9 , wherein the first front weft inlaid yarn forms a loop at a throat area of the upper.

15 . The integrally warp knit upper of claim 14 , further comprising a lace that extends through the loop.

16 . The integrally warp knit upper of claim 9 , further comprising a first back weft inlaid yarn that extends through every successive loop in the first warp knit course and a second back weft inlaid yarn that extends through every successive loop in the second warp knit course, the first back weft inlaid yarn and the second back weft inlaid yarn positioned on a technical back of the integrally warp knit upper.

17 . A method of manufacturing a warp knit component, the method comprising:
knitting a plurality of warp knit courses that form a plurality of warp knit wales that extend in a material flow direction; and using a first front weft inlay feeder:
inlaying a first front weft inlaid yarn in a first warp knit course of the plurality of warp knit courses such that the first front weft inlaid yarn extends through at least one loop in the first warp knit course,
floating the first front weft inlaid yarn over a technical face of the warp knit component as the first front weft inlay feeder advances in the material flow direction, and
inlaying the first front weft inlaid yarn in a second warp knit course of the plurality of warp knit courses such that the first front weft inlaid yarn extends through at least one loop in the second warp knit course.

18 . The method of manufacturing the warp knit component of claim 17 , further comprising:
using a second front weft inlay feeder:
inlaying a second front weft inlaid yarn in a third warp knit course of the plurality of warp knit courses such that the second front weft inlaid yarn extends through at least one loop in the third warp knit course,
floating the second front weft inlaid yarn over the technical face of the warp knit component as the second front weft inlay feeder advances in the material flow direction, and
