What is the difference between warp-knitted and weft-knitted fabrics?

The difference between warp knitting and weft knitting;

1, structural ductility:

Warp knitting has limited ductility, usually slightly in the horizontal direction and almost no in the vertical direction.

Weft knitting has good extensibility in both longitudinal and transverse directions.

2, fabric removal:

Warp knitting is not easy to disassemble;

Weft knitting is easy to disassemble.

3, equipment debugging and transformation:

Warp knitting, which is complicated to adjust varieties and takes more time;

Weft knitting variety adjustment is simple and efficient.

4. Production efficiency:

Warp knitting, can only weave (weave) flat fabrics, can only weave semi-finished products;

Weft knitting can produce flat and cylindrical fabric rolls, which can be woven into clothing, garment pieces and forming fabrics.

5. Production capacity:

Warp knitting can only produce a certain batch.

Weft knitting can be produced in small batches (even 1 kg).

Extended data:

The difference between warp knitting and weft knitting is that:

The coils formed by it are arranged along the vertical direction or the warp direction, and are formed by mutually sleeving adjacent yarns. The machine used for warp knitting looks a bit like a loom. All the yarns are wound on the warp beams behind and above the knitting area, and all the yarns are fed into the knitting area at the same time.

In the process of casing, each yarn is controlled by a separate needle. However, the yarn guide controls the position of the yarn, and the needle used in each loop may change. Jacquard mechanism can be used to control knitting needles and produce warp knitted fabrics with complex patterns. In view of the characteristics of warp knitting technology, the position of yarn supply device and the mutual socket between parallel yarns, it is sometimes called warp knitting machine.

Weft-knitted fabric is a kind of weft-knitted fabric in which knitting needles form one or more yarns in turn along the transverse direction of the fabric at the same time and are nested with each other in the longitudinal direction. A weaving method in which yarns running in the weft direction are bent up and down step by step to form loops, which are inserted into the loops formed by the previous yarns in turn, and are circularly wound into cloth.

Warp knitting refers to the method of connecting fabrics with longitudinal loops of warp yarns in knitting.
