Example 1
1-2, a waterproof and impervious coating cloth comprises a base cloth layer, a skin-friendly layer, a first waterproof layer, a high-density moisture absorption layer and a second waterproof layer; the base cloth layer is woven by high-strength polyester fibers; the skin-friendly layer is arranged on one side of the base cloth layer; the skin-friendly layer is PP spun-bonded non-woven fabric; the first waterproof layer is arranged on one side of the base cloth layer far away from the skin-friendly layer, trapezoid holes are formed in the first waterproof layer, and hydrophilic auxiliary agents are coated on the trapezoid holes; the high-density moisture absorption layer is arranged on the outer surface of the first waterproof layer; the second waterproof layer is arranged on the outer surface of the high-density moisture absorption layer and is a waterproof permeation-resistant layer.
Specifically, the fineness of the high-strength polyester fiber is 1300D-1500D, and the high-strength polyester fiber has the advantages of high strength and stable structure. Furthermore, a trapezoid hole is formed in the first waterproof layer, and hydrophilic auxiliary agents are coated on the trapezoid hole; the trapezoid holes are formed by hot press molding through a die, so that the caliber of the side close to a user is larger than that of the side far away from the user, and sweat and the like of the user are absorbed as much as possible by utilizing the hydrophilic auxiliary agent on the trapezoid holes, so that the moisture absorption effect is achieved. And then sweat and the like are emitted to the outer surface of the cloth by utilizing the combined design of the trapezoid holes and the high-density moisture absorption layer. When the liquid contacts with the second waterproof layer of the outermost layer, the liquid has waterproof and permeation-resistant effects, and the liquid which permeates later is concentrated on the outer surface of the high-density moisture absorption layer, so that the liquid evaporates along with the change of time and temperature. Therefore, the high-density moisture absorption layer is designed with high count and high density. Further, the high-density moisture absorption layer is formed by weaving warp yarns and weft yarns, and the warp yarns are formed by alternately arranging pure cotton yarns and cellulose fiber yarns at intervals; the weft yarns are ramie fiber yarns. The cotton yarn of the high-density moisture absorption layer has a yarn count density of 40S, and the fabric of the high-density moisture absorption layer has a density of 400 pieces per square inch.
Furthermore, a layer of waterproof resin film is arranged on the fiber surface of the high-strength polyester fiber, specifically, the high-strength polyester fiber is immersed in the waterproof resin solution, so that a layer of waterproof resin film is attached to the fiber surface, and the purposes of water seepage prevention and water prevention are achieved. Preferably, the waterproof resin solution comprises the following components: 30 parts of polyethylene resin, 50 parts of plasticizer, 5 parts of stabilizer, 10 parts of superfine alumina, an ultraviolet absorber and 2 parts of heavy calcium carbonate. The waterproof resin film of the formula has the effects of water seepage resistance, mildew resistance, bacteriostasis, environmental protection and the like, and prolongs the service life of the whole cloth.
