Technical Field
[0001] This utility model relates to the field of textile technology, and more specifically, to a warm and comfortable polyester composite fabric. Background Technology
[0002] Polyester fabric is a textile woven from polyester fibers. Due to its good wrinkle resistance and shape retention, polyester fabric is widely used in the production of various garments, such as coats, bags, and outdoor products like tents. In the home textile industry, polyester fabric is also used to make bedding and various decorative fabrics. In addition, polyester fabric is also widely used in industries such as metallurgy, forestry, chemical, petroleum, and fire protection.
[0003] However, polyester fabric is usually quite thin, and during the weaving process, the warp and weft threads interweave to form dense pores in the fabric. This allows cold air from the outside to penetrate the fabric and come into contact with the skin when the garment is worn in winter, making it easy for the wearer's body temperature to be lost and resulting in poor warmth retention.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warm and comfortable polyester composite fabric to solve the problem of poor warmth retention of clothing made of polyester fabric.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The warm and comfortable polyester composite fabric includes a comfort layer and a heat storage layer that are fixedly connected to each other. Several recesses are provided on both sides of the heat storage layer, and heating elements are provided in each of the several recesses. A heat insulation layer is provided on the side of the heat storage layer away from the comfort layer. Several warm insulation spaces are formed between the several recesses and heating elements on the side of the heat storage layer away from the comfort layer and the heat insulation layer. Several warm insulation spaces are formed between the several recesses and heating elements on the side of the heat storage layer away from the heat insulation layer and the comfort layer.
[0007] The present invention is further configured such that: a plurality of recesses on both sides of the heat storage layer are staggered along the length of the fabric, and the plurality of recesses are integrally formed by pressing the heat storage layer with a herringbone pleat; the diameter of the heating element is smaller than the width of the recess and larger than the depth of the recess.
[0008] The present invention is further configured such that: the side wall of the heating element abuts against the bottom surface of the recess; the side of the heating element protruding from the recess between the comfort layer and the heat storage layer abuts against the comfort layer; and the side of the heating element protruding from the recess between the heat insulation layer and the heat storage layer abuts against the heat insulation layer.
[0009] The present invention is further configured such that: a plurality of ventilation grooves are provided on the side of the heat storage layer away from the heat insulation layer, which are symmetrically arranged along the width direction of the fabric, and the adjacent heat preservation spaces are interconnected through the plurality of ventilation grooves.
[0010] The present invention is further configured such that: the comfort layer and the heat storage layer are provided with a plurality of ventilation holes, the plurality of ventilation holes on the heat storage layer are symmetrically arranged along the width direction of the fabric in a plurality of recessed bottoms on the side of the heat storage layer near the heat insulation layer, and the plurality of ventilation holes on the heat storage layer are interconnected with a plurality of heat preservation spaces.
[0011] The present invention is further configured such that: the plurality of vent holes on the heat storage layer are perpendicularly intersecting with and communicating with the plurality of vent grooves; the plurality of vent holes on the comfort layer are located directly below the plurality of vent grooves; and the plurality of vent holes on the comfort layer are communicating with the plurality of vent grooves.
[0012] The present invention is further configured such that: the comfort layer is made by weaving comfort yarn through a perforated structure, the comfort yarn is made by spirally wrapping a first strand around a second strand, the first strand is made by twisting cotton fibers, and the second strand is made by twisting hollow polyester shaped fibers.

[0014] The present invention is further configured such that: the heat insulation layer is a thin film made of polyurethane material, the heating element is cut by twisting multiple strands of heating yarn, and the heating yarn is cut by twisting the second and fourth strands after impregnation and coating with a moisture-absorbing and heat-generating finishing agent.
[0015] In summary, this utility model has the following beneficial effects: the heat-retaining layer made of several heat-insulating spaces one and two, as well as kapok fiber, allows the fabric to better retain the temperature generated by the body surface. The good heat insulation and windproof properties of polyurethane enable the heat-insulating layer to effectively block external gases from penetrating into the fabric, while preventing heat loss from the fabric.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] Example: This warm and comfortable polyester composite fabric, such as Figure 1 and Figure 5 As shown, the comfort layer 1 and the heat storage layer 2 are fixedly connected to each other. The comfort layer 1 is woven by feeding comfort yarn 10 into an air-jet loom and using a perforated weave. The comfort yarn 10 is made by spirally wrapping a first strand 11 around a second strand 12 using a ring spinning process. The first strand 11 is made by twisting cotton fibers using a twisting machine, and the second strand 12 is made by twisting hollow polyester profiled fibers using a twisting machine. The hollow polyester profiled fibers are spun through a spinneret. After being profiled, the polyester profiled fibers have a larger surface area, which improves their moisture absorption. Cotton fibers have good moisture absorption and softness, so the comfort layer 1 can absorb sweat produced by the skin in time when it comes into contact with the skin and provide a soft and comfortable touch.
[0026] like Figure 1 , Figure 2 and Figure 6As shown, the heat storage layer 2 has several recesses 3 symmetrically arranged along the length of the fabric on both sides. The recesses 3 on both sides of the heat storage layer 2 are staggered along the length of the fabric, which increases the surface area of the heat storage layer 2 in the fabric. A hot press is used to hot press several arc-shaped ventilation grooves 8 on the side of the heat storage layer 2 away from the heat insulation layer 5. After the ventilation grooves 8 are hot-pressed out, the heat storage layer 2 is integrally formed by pressing the staggered recesses 3 in a pleated manner. The heat storage layer 2 is woven by feeding the heat storage yarn 13 into an air-jet loom and weaving it with a perforated structure. The heat storage yarn 13 is formed by twisting a second strand 12 and a third strand 14 through a twisting machine. The third strand 14 is twisted from kapok fiber. Kapok fiber has a high hollow rate. The shaped polyester fiber has a larger gap, which makes the heat storage layer 2 effectively store the heat generated by the skin.
[0027] like Figure 1 and Figure 2 As shown, a cylindrical heating element 4 is provided in each of several recesses 3. The sidewall of the heating element 4 abuts against the bottom surface of the recess 3. The diameter of the heating element 4 is smaller than the width of the recess 3 and larger than the depth of the recess 3. The comfort layer 1 and the heat insulation layer 5 are sewn together and fixed using a sewing machine, so that the side of the heating element 4 located between the comfort layer 1 and the heat storage layer 2 protrudes from the recess 3 and abuts against the comfort layer 1, and the side of the heating element 4 located between the heat insulation layer 5 and the heat storage layer 2 protrudes from the recess 3 and abuts against the heat insulation layer 5. Heat transfer printing is used. The machine adds a heat insulation layer 5 to the end face of the heat storage layer 2 away from the comfort layer 1. After being supported by several heating elements 4, several indentations 3 and heating elements 4 on the side of the heat storage layer 2 away from the comfort layer 1 form several heat-insulating spaces 6 between the heat insulation layer 5 and the heat insulation layer 6. Several indentations 3 and heating elements 4 on the side of the heat storage layer 2 away from the heat insulation layer 5 form several heat-insulating spaces 7 between the comfort layer 1 and the comfort layer 2. Through several heat-insulating spaces 6 and heat-insulating spaces 7, a large amount of heat generated by the skin can be stored in the fabric.
[0028] like Figure 2 and Figure 7As shown, the insulation layer 5 is a thin film made of polyurethane. Polyurethane has good heat insulation and windproof properties. The insulation layer 5 can effectively block external air from penetrating into the fabric, while preventing heat loss from the fabric, thus giving the fabric a good warmth retention effect. The heating element 4 is made by twisting two strands of heating yarn 15 together using a twisting machine and then cutting it with a cutting machine. The heating yarn 15 is made by twisting a second strand 12 and a fourth strand 16 impregnated and coated with a moisture-absorbing and heat-generating finishing agent using a twisting machine. The moisture-absorbing and heat-generating finishing agent is polyacrylic acid, which can absorb moisture and generate heat. After absorbing the sweat emitted by the human body or the water vapor in the air, it releases heat. Polyester profiled fibers have good acid resistance, avoiding damage during the impregnation and coating process. The fourth strand 16 is made by twisting wool fibers through a twisting machine. Wool fibers have good moisture absorption and moisture regain. When wool fibers absorb moisture from the body surface and the air, the hydrophilic groups in the wool fibers will combine with water molecules, which will reduce the kinetic energy of the water molecules and convert it into heat energy. By adding several heating elements 4 in the fabric, the finished garment will generate heat when worn, further improving the warmth retention of the fabric.
[0029] like Figures 1-4 As shown, several ventilation slots 8 are symmetrically arranged along the width direction of the fabric, allowing adjacent insulation spaces 7 to communicate with each other. The comfort layer 1 and the heat storage layer 2 are perforated with several ventilation holes 9 of the same size. The ventilation holes 9 on the comfort layer 1 and the heat storage layer 2 are integrally formed by a perforated weave. The ventilation holes 9 on the heat storage layer 2 are symmetrically arranged along the width direction of the fabric at the bottom of several recesses 3 on the side of the heat storage layer 2 near the insulation layer 5, allowing the heat storage layer 2 to... The ventilation holes 9 on the heat storage layer 2 are all connected to the heat insulation space 6. The ventilation holes 9 on the heat storage layer 2 are all perpendicular to the ventilation grooves 8, so that the ventilation holes 9 on the heat storage layer 2 are all connected to the ventilation grooves 8. The ventilation holes 9 on the comfort layer 1 are all located directly below the ventilation grooves 8, so that the ventilation holes on the comfort layer 1 are all connected to the ventilation grooves 8. Through the ventilation grooves 8 and ventilation holes 9, the heat generated by the heating element 4 can be transferred to the skin, making the clothing warm and comfortable to wear.
