[0029] The upper fabric layer and the lower fabric layer are both obtained by interlacing warp yarns and weft yarns;

[0030] The interlacing includes: the first renewable polyester yarn 1 and the first renewable spandex yarn 2 are arranged in a radial close interlacing manner; the second renewable polyester yarn 3 and the second renewable spandex yarn 4 are arranged in a weft close interlacing manner; the convex points of the first renewable polyester yarn 1 and the second renewable spandex yarn 4 overlap on the fabric layer, and the convex points of the first renewable spandex yarn 2 and the second renewable polyester yarn 3 overlap;

[0033] Specifically, the upper fabric layer and the lower fabric layer are bonded by the heat-insulating adhesive layer, which not only has good bonding effect, but also plays a heat-insulating role. Through the heat-insulating adhesive layer, the high-temperature resistance of the fabric is improved, and the anti-deformation ability is also significantly improved, ensuring the stability and functionality of the garment in a high-temperature environment.

[0035] Further, the thickness of the fabric knitted by the ordinary yarn is about 50-150pm, and the fabric layer with a thickness of 200-300pm is formed by tightly knitting the high-density warp and weft, so that the fabric has more excellent anti-deformation ability in a high-temperature environment, and different thicknesses of the fabric can be knitted by controlling the density of the warp and weft according to actual needs, so as to ensure a suitable wearing experience.
