Warp knit component with weft inlays
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.
