How to distinguish between weft knitted fabrics and warp knitted fabrics

How to distinguish between weft knitted fabrics and warp knitted fabrics? Knitted fabrics are made up of loops connected in series. According to different knitting methods, they can be divided into two categories: weft knitted fabrics and warp knitted fabrics. Weft knitted fabrics are woven by circular knitting machines with tuck and loop formation, while warp knitting fabrics are knitted by flat knitting machines.
Compared with weft knitted fabrics, warp knitted fabrics generally have less extensibility. Most weft knitted fabrics have significant extensibility in the transverse direction. The extensibility of warp knitted fabrics is related to the number of combs and organization. Some warp-knitted fabrics are extensible in both the transverse and longitudinal directions, but some fabrics have good dimensional stability.
Weft-knitted fabrics, such as common sportswear, underwear, socks, hand-knitted sweaters and other fabrics, are woven with weft yarns sequentially and transversely to form loops. In warp knitting, all knitting needles are placed into loops at the same time.

Distinguishing
The simple and intuitive way to identify is to observe. If the front and back lines are the same, it is weft knitting, and if it is vertical, it is warp knitting. Generally speaking, weft knitting is divided into plain weave, rib weave and double-sided weft. Warp knitting is divided into warp plain, warp chain, warp satin and warp velvet. Moreover, warp knitting cannot be separated, while weft knitting can be separated in the weft direction.
The simple method is: warp knitting coils cannot be disassembled, but weft knitting coils can be pulled apart. As long as you pull the coil, you will know whether it is warp knitted or weft knitted. As long as you use your hands to pull the two pieces of fabric in the transverse direction (warp direction), the warp knitted fabric cannot be pulled, while the weft knitted fabric has obvious elasticity.
Warp knitting uses multiple yarns to form loops sequentially along the longitudinal direction (warp direction) of the cloth surface at the same time.
Weft knitting uses one or more yarns to form loops sequentially along the transverse direction (weft) of the department.
Weft knitted fabrics can be formed with at least one yarn, but in order to improve production efficiency, multiple yarns are generally used for knitting;
Warp knitted fabrics cannot be formed with one yarn For fabrics, one yarn can only form a loop-shaped object.
All weft knitted fabrics can be separated into threads in the opposite direction of knitting, but warp knitted fabrics cannot.
Warp knitted fabrics cannot be knitted by hand.
