Weft knitted fabric
Refers to a knitted fabric that is woven from the transverse direction. That is, the weft knitting machine makes the yarn reciprocating (or circular motion) from one side of the machine to the other side, and a new knitting stitch can be formed by the movement of the knitting needle. The weft knitted fabric yarn travels in a transverse direction, and the fabric is formed by weaving a row of yarns in a row and a row in a row direction. All the coils of a row are woven from a single yarn. The weft knitted fabric can be finished on a flat knitting machine or a circular machine.
Warp knitted fabric
Warp-knitted yarns are warp-knitted in warp-knitted fabrics, like the warp yarns of woven fabrics, which are fed by warp beam and are wound on the shaft with a large number of parallel-arranged yarns, similar to the warp beam in the weaving. . The direction of the yarn in the warp knit is warp. A vertical coil is formed in one course and then moved diagonally to the other wales to form another coil in the next course. The yarn advances in a zigzag shape from one side to the other along the length of the fabric, and each of the stitches in a row is made of a different yarn.
Comparison of warp knitting and weft knitting:
1: Extensibility of the fabric:
(1) Warp knitting—-Extension is limited, usually slightly lateral, and almost no vertical.
(2) Weft knitting—-Longitudinal and horizontal are better extension.
2: Fabric dismantling:
(1) Warp knitting—-Not easy to break up;
(2) Weft knitting—-Easy to break.
3: Device debugging conversion:
(1) Warp knitting—-Regulating varieties is complicated and time is spent more;
(2) Weft knitting—- Adjust the variety is simple, high efficiency.
4: Production efficiency:
(1) Warp knitting—-Weaving flat fabrics only, weaving semi-finished products;
(2) Weft knitting — Can produce flat and cylindrical fabric rolls, which can be woven into garments, garments and molded fabrics.
