The difference between warp and weft knitted fabrics-Part 2
1. The principle of weaving Bai is different
The principle of warp knitting is that one or more groups of parallel Du yarns are arranged on the knitting needles and woven in loops along the longitudinal (Warp) sequence at the same time.
The weaving principle of weft knitting is to feed one or more yarns into the working needle of the knitting machine from the transverse direction (weft direction), so that the yarns are sequentially bent into loops and formed by stringing.
2. Different yarn: weft knitted fabric can be formed with at least one yarn, but in order to improve production efficiency, more than one yarn is generally used for weaving; while for warp knitted fabric, one yarn can only form a chain fabric composed of one coil.
All weft knitted fabrics can be separated into threads against the knitting direction, but warp knitted fabrics cannot. Warp knitted fabrics cannot be woven by hand.
3. The extensibility of fabrics is different: warp knitting has limited elongation, which is usually a little bit lateral and almost no longitudinal. Weft knitted fabric has good elongation in both longitudinal and transverse directions.
