Comfortable breathable warp-knitted fabric free of deformation, yarn hooking and unraveling

A comfortable breathable warp-knitted fabric free of deformation, yarn hooking and unraveling, comprising a fabric body formed by warp-knitting four strands of yarns, wherein the four strands of yarns are respectively a first yarn, a second yarn, a third yarn and a fourth yarn;

• the first yarn stretches across three longitudinal stitch lengths and is fed alternatively to form a loop such that a warp-knitted structure formed by knitting the first yarn is a closed-end satin stitch;
• the second yarn is alternatively fed on two adjacent needles to form a loop such that a warp-knitted structure formed by knitting the second yarn is a closed-end tricot stitch;
• the third yarn and the fourth yarn are periodically inserted into the closed-end tricot stitch formed by knitting the second yarn such that warp-knitted structures formed by knitting the third yarn and the fourth yarn are respectively weft laid-in stitches;
• the weft laid-in stitch formed by knitting the third yarn is of a structure of one stitch length, and the weft laid-in stitch formed by knitting the fourth yarn is of a structure of two stitch lengths.
