Description

Warp knitting style circular knitting machine fabric and preparation method thereof

Technical Field

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

Background

Weft-knitted fabrics are usually made of low-stretch polyester yarns or special-shaped polyester yarns, nylon yarns, cotton yarns, wool yarns and the like as raw materials, and are knitted on various weft knitting machines by adopting plain stitch, variable plain stitch, rib stitch, double rib stitch, jacquard weave, terry stitch and the like. The weft knitting fabric has more varieties, generally has good elasticity and extensibility, is soft, firm and wrinkle-resistant, has stronger wool type, and is easy to wash and dry. The main defects are poor moisture absorption, stiff and smooth fabric, easy loosening and curling, and easy fluffing, pilling and yarn hooking of chemical fiber fabric. Warp-knitted fabrics are usually made from synthetic filament yarns of polyester, nylon, polypropylene, etc., and also from cotton, wool, silk, hemp, chemical fiber and blended yarns thereof. The common warp knitted fabric is usually knitted with a chain stitch, a warp plain stitch, a warp satin stitch, a warp bias stitch, or the like. The fancy warp knitting fabric is of various types, and mesh fabric, loop fabric, pleated fabric, plush fabric, weft insertion fabric and the like are common. The warp knitted fabric has the advantages of good longitudinal dimension stability, stiff and smooth fabric, small detachability, no curling, good air permeability and the like. The cross direction stretch, elasticity and softness are inferior to weft knitted fabrics. Because of the high 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. For example, patent application No. 202111339434.0 discloses a unidirectional wet-guide weft-knitted warp-knitted imitated small-grid elastic fabric and a preparation method thereof. The patent only carries out one-way moisture-conducting treatment on the weft-knitted warp-like fabric, but the weft-knitted warp-like fabric has poor stereoscopic impression, and how to obtain a warp-knitted style and a fabric with strong stereoscopic impression, ventilation and comfort through weft-knitted warp-like fabric is a problem to be solved.
