The invention discloses warp-knitting elastic zigzag-design thermal fabric. The warp-knitting elastic zigzag-design thermal fabric is prepared from, by mass, 28-31% of 30-32 s white ACR yarn, 28-31% of 30-32 s black cotton yarn and 38-44% of 75D40D polyester package spandex. The fabric is has a single-combing weave structure of GB1 combing and GB2 combing, wherein the white ACR yarn and the blackcotton yarn are adopted for GB1 combing and spaced, and the 75D40D polyester package spandex is adopted for GB2 combing. The warp-knitting elastic zigzag-design thermal fabric is simple in technologyand low in cost, the flexibility of existing woven zigzag-design fabric and the dimensional stability of existing weft-knitting zigzag-design fabric on the market are improved, the elastic recovery ofthe weft-knitting zigzag-design fabric is improved, and the warp-knitting elastic zigzag-design thermal fabric is comfortable to wear, fitting and attractive; thanks to the dual-way elasticity, lightness and comfort of the warp-knitting elastic fabric, a user does not feel constrained when wearing the warp-knitting elastic zigzag-design thermal fabric, and the warp-knitting elastic zigzag-designthermal fabric does not bulge or deform.
