[0019] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0020] Embodiment: The warm and comfortable composite fabric, such as Figure 1 As shown, it includes a comfort layer 1 and a heat insulation layer 2 fixedly connected to each other. The side of the heat insulation layer 2 away from the comfort layer 1 is covered with a windproof layer 3 by heat transfer processing. The windproof layer 3 is a film made of polyurethane material by a cast film processing method. The polyurethane film has good windproof and heat-insulating functions, so that the windproof layer 3 can effectively block the air circulation on both sides of the fabric, avoid cold air penetrating the fabric and contacting the skin and taking away the heat in the fabric, so that the fabric has good windproof performance. The polyurethane film has good flexibility and tear resistance, so that the windproof layer 3 can stretch and rebound with the fabric, avoiding damage to the windproof layer 3 after stretching. At the same time, the high wear resistance of the polyurethane material protects the fabric.

[0021] like Figure 1 and Figure 4 As shown, the thermal insulation layer 2 is made by feeding the thermal insulation yarn 15 into an air-jet loom and weaving it in a plain weave manner. The weaving density of the thermal insulation layer 2 is 192*186 / cm². By increasing the weaving density, the gaps in the thermal insulation layer 2 are reduced to prevent the heat in the fabric from being transmitted from the thermal insulation layer 2. The thermal insulation yarn 15 is made by spirally winding a third strand 16 on a second strand 14 through a ring spinning process. The second strand 14 is twisted by polyester fiber. Polyester fiber has high strength and wrinkle resistance, which prevents the fabric from wrinkling, deforming and losing elasticity after a period of use. The third strand 16 is twisted by wool fiber. Wool fiber has good thermal insulation effect. Polyester fiber has poor air permeability, so the thermal insulation layer 2 made of a blend of polyester fiber and wool fiber can effectively prevent the temperature loss in the fabric. The polyurethane material has good thermal insulation properties, and the temperature transfer on both sides of the fabric can be effectively blocked through the thermal insulation layer 2 and the windproof layer 3.

[0022] like Figure 1-Figure 3 As shown, the comfort layer 1 is made by feeding the comfort yarn 11 into an air-jet loom and weaving it through a perforated structure. The comfort yarn 11 is made by spirally winding a first strand 13 on a second strand 14 through a ring spinning process. The first strand 13 is twisted by a twisting machine to form cotton fibers. Cotton fibers are soft and skin-friendly. The comfort layer 1 is made by wrapping cotton fibers with polyester fibers to provide a soft and comfortable touch when in contact with the skin. At the same time, the cotton fibers also have certain warmth retention properties, which further enhances the warmth retention effect of the fabric.

[0023] like Figure 1-Figure 3 As shown, the thermal insulation layer 2 is provided with a number of depressions 4 and a number of protrusions 5 on both sides respectively. The number of depressions 4 are symmetrically arranged on the side of the thermal insulation layer 2 close to the windproof layer 3 along the length direction of the fabric, and the number of protrusions 5 are symmetrically arranged on the side of the thermal insulation layer 2 close to the comfort layer 1 along the length direction of the fabric, so that a number of warm spaces 6 are formed between the number of depressions 4 and the windproof layer 3, and the end of the protrusion 5 away from the windproof layer 3 is against the heat storage layer 10. The thermal insulation layer 2 and the number of heating elements 7 are fixedly connected to the comfort layer 1 after being sewn back and forth on the bottom surface of the number of depressions 4 by the comfortable yarn 11, so that a number of warm spaces 8 are formed between the number of adjacent protrusions 5 and the comfort layer 1 and the thermal insulation layer 2. The gap inside the fabric is increased by the number of warm spaces 6 and the warm spaces 8, so that more heat can be stored to achieve the effect of continuous warmth.

[0024] like Figure 1 and Figure 2 As shown, a heating element 7 is provided in each of the several recesses 4. The heating element 7 is formed by hot pressing the shortened wool fibers. When the wool fibers absorb moisture, the molecules inside the wool fibers interact with the water molecules, so that part of the kinetic energy of the water molecules is converted into heat energy, thereby achieving the effect of moisture absorption and heat release. By adding several heating elements 7 made of wool fibers in the fabric, the fabric can absorb moisture from the wearer's skin or the surrounding environment in time when worn, thereby releasing heat to generate a sense of warmth. The peripheral walls of the recesses 4 and the peripheral walls of the heating elements 7 are penetrated by a plurality of through grooves 9 that are interconnected with the warming space 1 6 and the warming space 2 8. The comfort layer 1 is penetrated by A plurality of ventilation holes 12 arranged in an array are provided through the fabric, and the ventilation holes 12 are all made by weaving a perforated tissue. The ventilation holes 12 are arranged between a plurality of adjacent protrusions 5 along the length direction of the fabric, so that the ventilation holes 12 are interconnected with a plurality of thermal insulation spaces 8. The heat generated by the heating element 7 can be transferred to the skin through the plurality of through grooves 9 and the ventilation holes 12. A heat storage layer 10 is integrally formed on the side of the comfort layer 1 close to the thermal insulation layer 2. The heat storage layer 10 is integrally formed on the comfort layer 1 by a sanding machine. The heat storage layer 10 allows the temperature inside the fabric to be better retained, thereby achieving the effect of keeping the fabric warm and comfortable when worn.

[0025] like Figure 1 、 Figure 5 、 Figure 6 and Figure 7 As shown, the processing equipment for warm and comfortable composite fabrics includes an equipment body 17 made of aluminum alloy. The equipment body 17 includes a glue coating roller 18, a flocking chamber 19, a hot pressing cutting device 20, a conveying roller 1 21, a conveying roller 22, a guide roller 23, a sewing device 24 and a heat transfer roller 25 arranged in sequence along the conveying direction of the thermal insulation layer 2. The woven thermal insulation layer 2 is conveyed to the equipment body 17, the woven comfort layer 1 is rolled up and conveyed to the equipment body 17 through the conveying roller 1 21, and the windproof layer 3 is formed. After winding, it is conveyed to the equipment body 17 through the conveying roller 22. The glue coating roller 18 is against the top surface of the thermal insulation layer 2. Grooves 32 are provided on both sides of the glue coating roller 18. The width of the opening of the groove 32 is the same as the distance between adjacent heating elements 7, so that the glue coating roller 18 can apply glue on the thermal insulation layer 2 at intervals when rotating. A cutting machine is used to place the shortened wool fibers in the flocking chamber 19, so that when the area on the thermal insulation layer 2 where glue is coated is conveyed to the flocking chamber 19, the wool fibers in the flocking chamber 19 will stick to the thermal insulation layer 2 and be conveyed together with the thermal insulation layer 2.

[0026] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the hot pressing cutting device 20 includes an extrusion 26 and a cutting member 27 located on both sides of the insulation layer 2. Two telescopic rods 33 are provided at the top of the extrusion 26 to drive it to move up and down. The telescopic rods 33 drive the hydraulic pump through the hydraulic motor 34 to extract hydraulic oil from the oil tank and send it to the hydraulic cylinder. The reciprocating movement of the telescopic rods 33 is achieved by the extension and contraction of the hydraulic cylinder, so that the extrusion 26 can reciprocate along the height direction of the equipment body 17. The end of the extrusion 26 close to the insulation layer 2 is an arc-shaped protrusion 28. The curvature of the protrusion 28 is the same as the curvature of the depression 1 4. The peripheral wall of the protrusion 28 is symmetrically provided with a plurality of cutting grooves 29 along its length direction. The protrusion 28 is integrally formed when the extrusion 26 is prefabricated. The plurality of cutting grooves 29 are cut on the peripheral wall of the protrusion 28 by a cutting machine. The extrusion 26 is made of copper material. Copper has good thermal conductivity, so that the extrusion 26 can achieve a thermoplastic setting effect when it is in contact with the fabric or fiber.

[0027] like Figure 1 、 Figure 2 、 Figure 6 and Figure 8As shown, the cutting piece 27 is close to the end of the heat insulation layer 2 and has an arc-shaped recess 2 30. The curvature of the recess 2 30 is the same as the curvature of the protrusion 1 5. The recess 2 30 is integrally formed when the cutting piece 27 is prefabricated. The concave surface of the recess 2 30 is symmetrically provided with a plurality of blades 31 made of aluminum alloy along its length direction. The plurality of blades 31 are fixedly connected in the recess 2 30 by a welding process. The distance between adjacent blades 31 is the same as the distance between adjacent through grooves 9 and the distance between adjacent cutting grooves 29. The width of the blade 31 is smaller than the width of the cutting groove 29. The plurality of blades 31 are located directly below the plurality of cutting grooves 29, so that the extrusion piece 26 is located close to the cutting After the member 27 moves downward, several blades 31 can be inserted into the cutting groove 29. When the thermal insulation layer 2 and the wool fibers fixed on its surface by glue are transported to the hot pressing cutting device 20 together, the extrusion member 26 moves downward in the direction close to the cutting member 27 and drives the thermal insulation layer 2 and the wool fibers fixed by glue to move downward together in the direction close to the cutting member 27. Several blades 31 penetrate the thermal insulation layer 2 and the wool fibers fixed by glue at the same time to form several through grooves 9. At the same time, the thermal insulation layer 2 and the wool fibers fixed by glue are hot-pressed by the extrusion member 26 to form a depression 4, a protrusion 5 and a heating element 7, thereby improving the processing efficiency of the equipment body 17 on the fabric.

[0028] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the glue coating roller 18, the conveying roller 1 21, the conveying roller 22, the guide roller 23 and the thermal transfer roller 25 are all driven by a motor and rotated and connected to the equipment body 17. The guide roller 23 changes the conveying direction of the comfort layer 1 so that the comfort layer 1 can be abutted against the end of the protrusion 1 5 away from the thermal insulation layer 2 during transportation. When the end of the protrusion 1 5 abutting against the comfort layer 1 is simultaneously conveyed to the top of the sewing device 24, the driving motor 35 drives the sewing device 24 to use the comfortable yarn 11 to sew the comfort layer 1, the thermal insulation layer 2 and the heating element 7 together. This sewing device 24 is an electric sewing machine. The thermal transfer roller 25 is made of copper. The conveying direction of the windproof layer 3 is changed by the thermal transfer roller 25 so that the windproof layer 3 is abutted against the top surface of the thermal insulation layer 2. At the same time, the windproof layer 3 is covered on the thermal insulation layer 2 by the thermal transfer roller 25, thereby completing the production of the fabric.

[0029] like Figures 1-8 As shown, the processing method of the device body 17 includes: Step 1: The heat-insulating layer 2 made of the heat-insulating yarn 15 is conveyed onto the device body 17, and the comfort layer 1 made of the comfort yarn 11 and the windproof layer 3 made of the polyurethane material are rolled up and conveyed onto the device body 17 via the conveying roller 1 21 and the conveying roller 2 22 respectively; Step 2: Glue is applied to the top surface of the thermal insulation layer 2 at intervals by rotating the glue coating roller 18; Step 3: Place the cut wool fibers in the flocking chamber 19. When the heat insulation layer 2 coated with glue is transported into the flocking chamber 19, the wool fibers are fixed to the heat insulation layer 2 by the glue and transported together. Step 4: The extrusion member 26 is moved downward in a direction close to the cutting member 27, so that the heat storage layer 10 and the wool fibers fixed with glue are respectively pressed against the second depression 30 and the second protrusion 28 by heat pressing to form the first protrusion 5, the first depression 4 and the heating element 7. At the same time, a plurality of blades 31 penetrate the heat storage layer 10 and the heating element 7 to form a plurality of through grooves 9. Step 5: The conveying direction of the comfort layer 1 is changed by the guide roller 23 so that it abuts against the protrusion 1 5 , and then the comfort layer 1 , the insulation layer 2 and the heating element 7 are sewed and fixed by the sewing device 24 ; Step 6: Use the heat transfer roller 25 to cover the windproof layer 3 on the side of the heat storage layer 10 away from the comfort layer 1.
