Warp Knitting
category
Warp knitting forms fabric by creating vertical columns (wales) where each needle loop is formed by multiple warp yarns (each needle fed from separate yarn beam), with yarns zig-zagging between needles in controlled patterns. Produces 35-40% of knitted fabrics (~16 billion m² annually) via tricot (50%), raschel (40%), and specialty machines (10%), achieving speeds up to 2,000 courses/minute with superior dimensional stability and run-resistance compared to weft knits.
Role
Dominates technical textile markets (automotive textiles, geotextiles, medical textiles, narrow fabrics) and fashion segments requiring stability with drape (lingerie, swimwear, activewear, lace), combining knit advantages (one-step fabric formation, design flexibility, stretch) with woven-like stability (minimal curl, excellent dimensional stability, run-resistance) making it essential for applications requiring controlled stretch and structural integrity.
