Specialty Warp Knitting Technologies

Advanced warp knitting systems: Multiaxial warp knitting—inserting additional yarn systems (0°, 90°, ±45° orientations) secured by warp knit chain, creating multi-directional reinforcement for composites (wind turbine blades, automotive, aerospace), combines woven-like anisotropic strength with knit formability, production rates 5-30 m²/hr depending on complexity, weight 200-2000 GSM. Crochet/Malimo—high-speed stitch-bonding of warp-inserted yarns (not true knitting, but warp-knit-like chain securing parallel yarns), producing very stable fabrics 500-2,000 m/min, used for interlinings, technical substrates, eliminating yarn crimp maintaining full strength. Jacquard raschel—electronic jacquard control (individual guide bar element selection) enabling complex patterns in lace, curtains, upholstery without mechanical pattern system limitations, pattern changes via computer (seconds vs. hours for mechanical), unlimited repeat size, resolution up to 12-18 needles/inch, speeds 200-800 courses/min (slower than plain raschel due to complexity). Stitch-bonded nonwovens—combining warp knit chain with laid web (parallel fibers, random web, or fabric) creating composite structures, used for geotextiles, interlining, filtration, automotive (combining fiber web strength/cover with knit structure), production 50-300 m/min, 50-500 GSM range.
