Description

Warp knitting style circular knitting machine fabric and preparation method thereof

Technical Field

The invention relates to the technical field of textile, in particular to a warp knitting style circular knitting machine fabric and a preparation method thereof.

Background

Weft knitting fabrics are usually woven on various weft knitting machines by taking low-elastic polyester yarns or special-shaped polyester yarns, nylon yarns, cotton yarns, wool yarns and the like as raw materials and adopting plain stitch, variable plain stitch, rib stitch, double rib stitch, jacquard stitch, looped pile stitch and the like. The weft knitting fabric has more varieties, generally has good elasticity and extensibility, is soft, firm and crease-resistant, has stronger wool type, and is easy to wash and dry. The main defects are poor hygroscopicity, the fabric is not stiff and smooth enough, and is easy to scatter and curl, and the chemical fiber fabric is easy to fuzzing, pilling and hooking. Warp knitted fabrics are usually woven from synthetic filaments such as polyester, nylon, polypropylene and the like, and also from cotton, wool, silk, hemp, chemical fibers and blended yarns thereof. Common warp knit fabrics are often woven with chain stitches, warp plains, warp satins, warp plains, and the like. The fancy warp knit fabrics are of various kinds and are commonly known as mesh fabrics, terry fabrics, gathered fabrics, plush fabrics, weft inserted fabrics and the like. The warp knitting fabric has the advantages of good longitudinal dimensional stability, stiff and smooth fabric, small stripping property, no curling, good air permeability and the like. Lateral elongation, elasticity and softness are inferior to weft knitted fabrics. Because of higher warp knitting cost, a knitting method for obtaining warp knitting style by weft knitting is needed, so that the weft knitting fabric also has the advantages of good air permeability, stable size and the like of the warp knitting fabric. The patent with the application number 202111339434.0 discloses a unidirectional moisture-conducting weft knitting imitation warp knitting small square elastic fabric and a preparation method thereof. The patent only carries out one-way moisture-guiding treatment on the weft-knitted warp-knitted imitation fabric, but the three-dimensional effect of the weft-knitted warp-knitted imitation fabric is not strong, and how to obtain warp-knitted styles and fabrics with strong three-dimensional effect, ventilation and comfort through weft-knitted warp-knitted imitation is a problem to be solved.
