DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0024] A coated fabric, such as Figure 1 As shown, it includes a fabric layer 8 and a film layer 9. The fabric layer 8 is woven from polyester fibers. The film layer 9 is a non-porous waterproof and breathable film. The film layer 9 is folded to form a plurality of moisture-discharging parts 902 distributed at intervals. The moisture-discharging parts 902 surround a heat storage groove 12 with a groove bottom facing the fabric layer 8. The film layer 9 is provided with an attachment part 901 between adjacent moisture-discharging parts 902. The fabric layer 8 and the plurality of attachment parts 901 are bonded to each other through a moisture-conducting adhesive 10. The moisture-discharging part 902 includes a first fold and a second fold adjacent to the fabric layer 8 in sequence. The moisture-discharging part 902 is fixedly bonded to the moisture-discharging part 902 and the attachment part 901 at the position of the second fold, so that the moisture-discharging part 902 and the attachment part 901 surround each other to form a heat-insulating cavity 13. The moisture-conducting adhesive 10 is mixed with moisture-conducting staple fibers 11. The moisture-conducting staple fibers 11 are made by cutting special-shaped fibers by a slitting machine. The special-shaped fibers are subjected to oleophobic treatment. The special-shaped fibers are formed by spinning polyester materials, and their cross-sections are Y-shaped structures.

[0025] After the moisture generated by the evaporation of sweat passes through the fabric layer 8, a part of it is directly discharged through the moisture discharge part 902 through the film layer 9 to the outside of the coated fabric, and the other part enters the heat storage tank 12 and can choose to pass through the film layer 9 to enter the heat preservation cavity 13 or the outside of the coated fabric. Since the heat storage tank 12 wraps the heat preservation cavity 13, the inner walls of the heat storage tank 12 and the heat preservation cavity 13 can condense moisture, and continuously form moisture in the subsequent process and exchange moisture through the film layer 9, so that the heat dissipated by the body can be transferred back and forth in the heat storage tank 12 and the heat preservation cavity 13, so that the heat dissipation rate is slowed down, and due to the characteristics of the waterproof and breathable film, the sweat discharged into the heat preservation cavity 13 and condensed into liquid will not directly flow back to the fabric layer 8, so that the sweat condensed in the heat preservation cavity 13 is prevented from transferring heat with the sweat in the fabric layer 8, and the moisture permeability of the coated fabric is maintained while the heat preservation performance of the coated fabric is improved;

[0026] At the same time, the groove structure formed on the surface of the moisture-conducting staple fiber 11 is used to conduct moisture in both directions on the sweat in the fabric layer 8, which can accelerate the flow rate of sweat between the heat storage tank 12 and the fabric layer 8, so that the temperature of the sweat in the heat storage tank 12 is maintained at a high state when wearing clothing made of the coated fabric for sweating, thereby improving the heat storage effect of the heat storage tank 12. In order to alleviate the situation where the grease mixed in the sweat blocks the groove structure of the moisture-conducting staple fiber 11 due to vigorous body oil secretion, the moisture-conducting staple fiber 11 is oleophobic.

[0027] Beneficial effect: Compared with the prior art, the coated fabric effectively utilizes the moisture conduction property of the waterproof and breathable film. By setting up the heat-insulating cavity 13, the rate at which moisture directly leaves the film layer 9 and drifts outside the coated fabric is slowed down, so that this part of moisture can use the heat it contains to maintain the temperature on the other side of the film layer 9. At the same time, the setting of the heat storage tank 12 also increases the moisture that passes through the film layer 9 and enters the heat-insulating cavity 13, and can also form mutual conduction with the moisture in the heat-insulating cavity 13, thereby further improving the heat storage performance of the coated fabric and improving the sweat-inducing effect of the sweat-inducing clothing made of this fabric.

[0028] like Figure 1As shown, specifically, the non-porous waterproof and breathable film is made of polyurethane material, the moisture-conducting adhesive 10 is based on polyurethane adhesive, and the non-porous waterproof and breathable film has a good thermoplastic effect. In order to make it easier for the moisture-conducting staple fibers 11 to conduct sweat, before the polyurethane adhesive is coated between the fabric layer 8 and the film layer 9, a number of moisture-conducting staple fibers 11 are evenly sprinkled on the polyurethane adhesive so that the moisture-conducting staple fibers 11 are upright between the fabric layer 8 and the film layer 9. In this way, the addition of the moisture-conducting staple fibers 11 can maintain the straightness of the moisture-conducting staple fibers 11 to a great extent. The volume ratio of the moisture-conducting staple fibers 11 to the polyurethane adhesive is 0.2 to 0.3. In order to facilitate the cleaning of the sweat retained in the insulation cavity 13, the moisture discharge portion 902 and the attachment portion 901 surround the insulation cavity 13 and are bonded by ultrasonic welding, and the surface of the ultrasonic welding welding head is an array-distributed arc surface structure.

[0029] A production device for coated fabrics, used to produce the above-mentioned coated fabrics, such as Figure 2 as well as Figure 3 As shown, it includes a frame 1 placed on the ground, and two transmission rollers 7 for transmitting a film layer 9 and a fabric layer 8 are rotatably connected to the frame 1. An indentation mechanism, a glue coating roller 3, a laminating roller 5 and a bonding mechanism 6 are installed on the frame 1, wherein the indentation mechanism includes two indentation rollers 2 that cooperate with each other by rotation, and the indentation rollers 2 are rotatably connected to the frame 1, and the two indentation rollers 2 mold a plurality of moisture-discharging portions 902 on the film layer 9, and the glue coating roller 3 and the laminating roller 5 are both rotatably arranged on the frame 1, and the glue coating roller 3 is used to apply a moisture-conducting adhesive 10 toward one side of the plurality of attachment portions 901, and the two laminating rollers 5 laminate the film layer 9 and the fabric layer 8 that have passed through the indentation mechanism and the glue coating roller 3, and the bonding mechanism 6 Used to bond the film layer 9 and the fabric layer 8, the frame 1 is also provided with an unwinding mechanism for unwinding the fabric layer 8 and the film layer 9 and a winding roller for winding the coated fabric, the creasing roller 2, the glue coating roller 3, the laminating roller 5 and the winding roller are driven by a plurality of motors fixedly arranged on the frame 1, the bonding mechanism 6 includes a cylinder fixedly arranged on the frame 1 and an ultrasonic welding machine reciprocatingly driven by the cylinder, the frame 1 is rotatably provided with a supporting roller for supporting the ultrasonic welding machine welding head, and the frame 1 is provided with a visual sensor for assisting the operation of the ultrasonic welding machine and an exhaust fan for cooling the surface of the coated fabric after ultrasonic welding on both sides of the ultrasonic welding machine;

[0030] Among them, the direction in which the lamination roller 5 transmits the film layer 9 is the same as the direction in which the several second folds on the film layer 9 are molded, so that the first fold and the second fold can be effectively bent by the lamination roller 5, and the shapes of the first fold and the second fold are more obvious. In order to stabilize the lamination rate of the film layer 9 and the fabric layer 8, a transmission roller 7 is arranged on one side of the creasing roller 2, and the transmission roller 7 is connected to a tension sensor for adjusting the transmission rate of the film layer 9.

[0031] A plurality of indentation grooves 202 are evenly formed on the circumference of one indentation roller 2, and a plurality of indentation blocks 201 are evenly fixedly disposed on the circumference of the other indentation roller 2. The two indentation rollers 2 can be rotated to allow the indentation blocks 201 to be embedded in the indentation grooves 202. The cross section of the indentation blocks 201 is shown in FIG. Figure 3 This shape can make the moisture-discharging part 902 formed by molding be inclined, so that the film layer 9 molded out of the moisture-discharging part 902 is more easily pressed by the pressing roller 5, and at this time, the cross-sectional shape of the plurality of moisture-discharging parts 902 along their arrangement direction is a Z-shaped structure, and the positions of the first fold and the second fold are in arc shape;

[0032] Each time the film layer 9 is molded by the indentation block 201, the film layer 9 is limited by the lamination roller 5 on one side of the molding position, and the film layer 9 on the other side of the molding position is adjusted in real time by the transmission roller 7 with a tension sensor by the unwinding mechanism, so that the film layer 9 always remains in a tension-free state.
