A warp knitting system may knit a seamless tube of fabric. The fabric may have a spacer between outer and inner fabric layers. The knitting system may have first and second needle guide systems. The first and second needle guide systems may each have selectively linked needle bed sections that guide respective needles. A guide bar system may have guide bars that dispense strands of material during knitting. Each guide bar may be positioned using a respective guide bar positioner. The guide bar system may be shifted relative to the needles using a rotational positioner. The needle guide systems and guide bar system may be formed from selectively coupled links. The selectively coupled links may be configured to adjust the diameter of the tube of fabric to a desired value. The thickness of the tube may be adjusted by adjusting a gap between the first and second needle guide systems.

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.

A visual barrier windscreen includes a first series of monofilament threads formed in pillar stitches extending in a warp direction and a second series of monofilament threads formed in zigzag stitches extending in a first weft direction relative to the pillar stitches and binding adjacent pillar stitches. A third series of monofilament threads may be formed in zig-zag stitches extending in a second weft direction, opposite to the first weft direction, and also binding adjacent pillar stitches. A pattern of hexagonal wind-passage holes may be formed by cooperation of the pillar stitches and zig-zag stitches. At least a 75-80% visual block may be attained with the cooperation of the pillar stitches and zig-zag stitches.

A knitted fabric for promoting heat dissipation is to be an insole and covers a wearer's skin when in use, and has two surface layers, an intermediate layer, and multiple channels. The two surface layers are disposed at a spaced interval, and include a first surface layer and a second surface layer oriented to the wearer's skin when the knitted fabric is in use. The second surface layer has multiple braids disposed parallelly, and each one of the multiple braids is straight and extends in a widthwise direction. The intermediate layer is formed with multiple monofilaments knitted between the two surface layers and divergently stretch out from each braid toward the first surface layer. Each monofilament intercrosses with another at a point near the first surface layer. A channel is formed among the intermediate layer and adjacent two said braids and has a V-shaped cross section.
