Warp knitting uses a series of yarns directed through guides around needles to form interlocking rows of loops. Woolmark describes the resulting structures as stable and difficult to unravel, with options ranging from open to closed fabrics. The process can create broad fabric widths and tubular or three-dimensional forms.

Warp Knitting Builds Wool Fabric from Parallel Yarn Systems

Modern machinery also supports products described as seamless, although final garment assembly may still require seams. The reference highlights opportunities in activewear and next-to-skin clothing, where structure and comfort matter. This makes warp knitting a construction choice within wool textiles, distinct from merely identifying the fiber or assuming every knitted garment is formed in the same way.
