Polyester-spandex interwoven cotton-wrapped knotless ultra-high-elasticity crude fiber mountaineering shoe fabric

The invention provides a polyester-spandex interwoven cotton-covered knotless ultra-high-elasticity crude fiber mountaineering shoe fabric, the fabric is formed by interweaving warp yarns and weft yarns, the warp yarns and the weft yarns are core-spun yarns, the warp yarns are formed by wrapping 150d polyester fibers with cotton fibers, and the weft yarns are formed by wrapping 840d spandex fibers with cotton fibers; the preparation method comprises the following steps: S1, respectively pretreating polyester fibers and spandex fibers, and then respectively coating the pretreated polyester fibers and spandex fibers with cotton fibers to obtain warp yarns and weft yarns; s2, the obtained warp yarn is subjected to warping on a warping machine and then subjected to denting, and the warping speed ranges from 120 m/min to 150 m/min; s3, weaving the obtained warp yarns and weft yarns to obtain gray fabric, namely the polyester-spandex interwoven cotton-wrapped knotless ultrahigh-elasticity crude fiber mountaineering
