The multi-layer tube of spandex core-spun yarn as claimed in claim 1, wherein the anti-slip layer is an electrical insulation tape layer, a zebra tape layer, an EVA material layer, a rubber material layer, a silica gel material layer, a latex material layer, a cloth layer or any soft non-metallic material layer, and the thickness thereof is 0.05-1 mm.
9. The multi-layer tube of spandex core-spun yarn according to claim 1, wherein the tube body comprises a straight or inclined tube body, the large-diameter end of the inclined tube body being a pressing start end and the small-diameter end being a pressing end; one end of the straight pipe body, which is provided with the anti-skid layer, is a yarn pressing starting end, and the other end without the anti-skid layer is a yarn pressing tail end; the end face of the tail end of the yarn pressing inclines towards the center direction of the tube body to form a slope with the vertical height being less than or equal to 15 mm.
10. The multi-layer tube of spandex core-spun yarn as claimed in claim 8, wherein the diameters of the large and small ends of the slant tube body are 1.4 to 2.5 times the diameters of the corresponding large and small ends of the slant dyed tube, and the diameter of the straight tube body is 1.4 to 2.5 times the diameter of the corresponding straight dyed tube, wherein the diameters of the large and small ends of the slant tube body and the diameter of the straight tube body refer to the outer diameter of the tube body after the buffer layer is provided.
