What Are The Characteristics Of Knitted Warp Knitted Fabrics?

Warp-knitted fabrics are often made of polyester, nylon, polypropylene and other synthetic filaments, as well as cotton, wool, silk, hemp, chemical fibers and their blended yarns. Ordinary warp knitted fabrics are often woven with chain weave, warp flat weave, warp satin weave, warp bias weave, etc. There are many types of fancy warp knitted fabrics, and the common ones are mesh fabrics, terry fabrics, pleated fabrics, plush fabrics, and weft-inserted fabrics. The warp knitted fabric has the advantages of good longitudinal dimensional stability, crisp fabric, small delamination, no curling, and good air permeability.

The name warp knitting comes from machine weaving, and the knitted fabric woven by warp knitting is called warp knitted fabric. The difference between warp knitting and weft knitting is that the loops it forms are arranged in the vertical direction or warp direction, and are formed by nesting adjacent yarns. The machine used for warp knitting looks somewhat like a loom, in that all the yarns are wound on warp beams, which are located behind and above the weaving zone, and all the yarns are fed into the weaving zone at the same time. During the nesting process, each yarn is controlled by an individual needle. However, the yarn guide bar controls the position of the yarn, and the needles used for each loop may vary. Needle control can be implemented using the jacquard mechanism to produce warp knitted fabrics with complex patterns. In view of the characteristics of the warp knitting process, the position of the yarn supply device, and the mutual nesting between parallel yarns, it is sometimes called a warp knitting machine.

Fundamentally, warp knitting is a processing system for producing open-width fabrics. The fabric has straight sides, high production speed and large output. Warp knitted fabrics can be classified according to the equipment used and the characteristics of the fabric, the main types are: Tricotta, Raschel, Milanese and Simplex, the most common being Tricotta and Raschel.
