AI Technical Summary
Traditional polyester home clothing has limited insulation capacity, especially when the indoor temperature is low in winter, heat is easily lost, resulting in poor warming performance.
A warm-inhibited polyester fabric is designed, including a polyester layer and a warm-inhibited layer. The warm-inhibited layer is arranged through an alternate array of heating zones and insulation zones. Several warm-inhibited rings are fixedly connected on both sides of the heating zone, and adjacent warm-inhibited rings are between them. The opening is equipped with a warm groove, and the polyester layer is fixedly connected to the side of the warmth layer with several warmth velvets arranged corresponding to the warmth ring.
The friction between the warm velvet and the warm ring generates heat, which increases the content of still air in the fabric and slows down heat loss. The heat generated in the heating zone is difficult to dissipate from the insulation zone, effectively improving the warmth effect of the fabric.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polyester cloth, and more specifically, to a warm-keeping polyester fabric. Background Art
[0002] Polyester fabric is a very commonly used chemical fiber clothing fabric in daily life. Polyester fabric has high strength and elastic recovery ability. Therefore, it is durable, wrinkle-resistant and ironing-free.
[0003] The structure of polyester fabric is flat and straight, but the surface of polyester yarn is smooth. Polyester fabric woven with polyester yarn will be relatively cool when in contact with the body surface, especially in winter when the indoor temperature is low and home clothes need to be worn. Traditional home clothes are generally made of polyester home clothes. The weaving structure of polyester home clothes is single, and there are many gaps between fibers, so heat is easily lost, which makes the thermal insulation capacity of polyester home clothes limited. Therefore, a structure needs to be set up to solve the problem of poor thermal insulation performance of polyester fabrics.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model aims to provide a warm polyester fabric.

[0007] The utility model is further configured as follows: the thermal insulation layer is configured as a plain weave, the warps of the heating zone and the thermal insulation zone are both configured as polyester yarns, the wefts of the heating zone include alternately arranged loop yarns and wool yarns, and the wefts of the thermal insulation zone are configured as acrylic yarns.
[0008] The utility model is further configured as follows: 33 wefts are provided in the heating zone, 17 of which are loop yarns and 16 are wool yarns, and 66 wefts are provided in the heat preservation zone.
[0009] The utility model is further configured as follows: the yarn count of the wool yarn is greater than the yarn count of the loop yarn, and the warm-keeping groove is arranged in the area where the wool yarn is located.
[0010] The utility model is further configured as follows: the loop yarn comprises a core yarn, a pressure yarn and a decorative yarn, the core yarn and the pressure yarn are both configured as polyester yarns, and the decorative yarn is configured as acrylic yarns.
[0011] The utility model is further configured as follows: the polyester layer is configured as a plain weave, and the weaving density of the polyester layer is equal to the weaving density of the heat preservation zone.
[0012] In summary, the utility model has the following beneficial effects:
[0013] When the fabric is made into clothes and worn, the thermal fleece on the polyester layer rubs against the thermal ring on the thermal layer, generating heat to increase the temperature of the fabric. At the same time, the setting of the thermal ring and the thermal fleece increases the content of still air in the fabric. The air has poor thermal conductivity, which can slow down the loss of heat in the fabric. The heat generated in the heat zone is difficult to dissipate from the insulation zone, thereby ensuring the warming effect of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] The warm polyester fabric, such as Figure 1 , Figure 2As shown, it includes a polyester layer 1, one side of the polyester layer 1 is fixedly connected to a thermal insulation layer 2, the polyester layer 1 is flat and straight, so as to support the fabric and prevent it from being deformed easily, the thermal insulation layer 2 increases the thickness of the fabric, can better block the heat exchange on both sides of the fabric, and improve the thermal insulation effect of the fabric, the thermal insulation layer 2 includes heating areas 3 and thermal insulation areas 4 arranged in an alternating array, the weaving density of the thermal insulation area 4 is twice the weaving density of the heating area 3, a plurality of thermal insulation circles 5 are fixedly connected on both sides of the heating area 3, and thermal insulation grooves 6 are provided between adjacent thermal insulation circles 5, and a plurality of thermal insulation fleeces 7 arranged corresponding to the thermal insulation circles 5 are fixedly connected to the side of the polyester layer 1 close to the thermal insulation layer 2, and the length of the thermal insulation fleece 7 is greater than the diameter of the thermal insulation circle 5.
[0021] like Figure 1 , Figure 2 As shown, when the fabric is made into clothes and worn, the side of the thermal fleece 7 away from the polyester layer 1 is against the side wall of the thermal insulation layer 2. With the movement of the human body, the thermal fleece 7 on the polyester layer 1 rubs against the thermal insulation ring 5 on the thermal insulation layer 2, generating heat to increase the temperature of the fabric. At the same time, the setting of the thermal insulation ring 5 and the thermal fleece 7 increases the content of still air in the fabric. The thermal conductivity of air is poor, which can slow down the heat loss rate in the fabric. The weaving density of the thermal insulation zone 4 is large, so its weaving pores are smaller. The heat generated in the heating zone 3 is difficult to dissipate from the thermal insulation zone 4 and can be better retained in the fabric.
[0022] like Figure 1-Figure 4 As shown, the thermal insulation layer 2 is configured as a plain weave, the warps of the heating zone 3 and the thermal insulation zone 4 are both configured as polyester yarns, the wefts of the heating zone 3 include alternating loop yarns and wool yarns, the loop yarns include core yarns, pressure yarns and decorative yarns, the core yarns and pressure yarns are both configured as polyester yarns, the decorative yarns are configured as acrylic yarns, the polyester yarns and acrylic yarns are woven by a fancy twisting machine in accordance with the weaving method of loop yarns to obtain loop yarns, so that the thermal insulation ring 5 can be integrally woven on the thermal insulation layer 2 during weaving, to avoid the thermal insulation ring 5 from falling off when the fabric is used and affecting its thermal insulation effect, while the polyester yarn has high strength and good supporting strength, can maintain the stability of the loop yarn, the acrylic yarn has good thermal insulation properties, and further slows down the loss of heat.
[0023] like Figure 1-Figure 4 As shown, the weft of the heat preservation zone 4 is set to acrylic yarn, the yarn count of the wool yarn is larger than the yarn count of the loop yarn, and the heat preservation groove 6 is set in the area where the wool yarn is located. The diameter of the wool yarn is smaller than the diameter of the loop yarn. Therefore, when weaving the heating zone 3, the wool yarn inserted at intervals will form a depression on the fabric, which is the heat preservation groove 6. There are many pores on the surface of the wool yarn, and the finer the wool fiber, the better the heat preservation effect.
[0024] like Figure 1-Figure 4As shown, the heating zone 3 is provided with 33 weft threads, of which 17 are loop yarns and 16 are wool yarns, the insulation zone 4 is provided with 66 weft threads, and the thermal insulation layer 2 is provided with 99 warp threads. The above numbers are expressed in terms of per square inch, and the width of the thermal insulation zone 4 is greater than the width of the heating zone 3 and less than twice the width of the heating zone 3 to ensure that the weaving density of the thermal insulation zone 4 is greater than the weaving density of the heating zone 3. The thermal insulation groove 6 is arranged between adjacent thermal insulation circles 5 arranged in strips. Therefore, the number of loop yarns is one more than the number of wool yarns, and the number of warp threads of the thermal insulation layer 2 is equal to the sum of the number of weft threads in the heating zone 3 and the number of weft threads in the thermal insulation zone 4. The arrangement of the warp threads and weft threads of the woven thermal insulation layer 2 is more uniform and smooth.
[0025] like Figure 3 , Figure 4 As shown, the polyester layer 1 is set to a plain weave, and the weaving density of the polyester layer 1 is equal to the weaving density of the insulation zone 4, so that the weaving density of the polyester layer 1 is also larger, which can better block the loss of heat. The polyester yarn is woven according to the weaving density of the plain weave, and the woven polyester layer 1 is napped in a specific area by a napping machine to form a number of warm fleeces 7.
[0026] like Figure 1-Figure 4 As shown, the polyester yarn is threaded and fixed on the water jet loom, the weft of the heating zone 3 is alternately inserted with the loop yarn and the wool yarn, and after the weft is beaten according to a fixed number, it is inserted into the weft of the insulation zone 4 to form a thermal insulation layer 2, and finally the thermal insulation layer 2 is placed on the polyester layer 1, and the thermal insulation loop 5 and the thermal insulation fleece 7 are placed correspondingly, and finally they are sewed and fixed by a sewing machine to complete the fabric processing process.
[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
