Warp Knitting
Warp knitting forms fabric from many parallel yarns supplied from beams, with each yarn making loops along the length of the fabric while guide bars lap it across needles. Tricot and raschel are the main machine types.
In warp knitting, a sheet of yarns from one or more warp beams is fed to a row of needles. Guide bars swing the yarns around the needles and shift them sideways, so each yarn forms loops that interconnect with those of neighbouring yarns. The lapping movements of the guide bars, described by lapping notation, determine the structure. Tricot machines are typically used for finer, flatter fabrics, while raschel machines handle a wider range of structures such as nets, laces and spacer fabrics.
Warp-knitted fabrics are used for lingerie, sportswear, linings, mesh, lace, curtains, automotive interior fabrics and technical textiles such as nets, geotextiles and medical textiles. The structure can be run-resistant and more dimensionally stable than many weft-knitted fabrics.
Warp knitting requires prepared warp beams with uniform tension, much like weaving, and a broken end can create a defect line along the fabric, so yarn quality and beam preparation are critical. Machines run at high speeds, and monitoring systems detect broken ends and fabric faults. Patterning and settings follow the machine manufacturer's documentation.

- Used for lingerie, sportswear, nets, lace and technical textiles
Where AiVibe comes in
AiAmbA use cases include visual inspection on textile and automotive lines, predictive maintenance and digital twins. Existing lines are retrofitted with edge devices, and AI agents only propose changes for a trained operator to confirm.
