Warp knitting uses multiple yarns to form a loop in the longitudinal direction (warp direction) of the fabric surface at the same time, and weft knitting uses one or more yarns to make a loop in the transverse direction (weft) of the fabric surface.
Weft knitted fabrics can be formed with at least one yarn, but in order to improve production efficiency, multiple yarns are generally used for weaving; warp knitted fabrics cannot be formed with one yarn, one yarn Only a coil of maggots can be formed. All weft knitted fabrics can be separated into threads in the reverse knitting direction, but warp knitted fabrics cannot.
Warp knits cannot be woven by hand. Weft knitted fabrics have stretchability, crimping, and loosening properties. Warp knitted fabrics have a stable structure and a small amount of elasticity because they form a loop around the knot
