Description

Technical Field

[0001] The utility model relates to the technical field of polyester cloth, and more specifically, to a warm-keeping polyester cloth. Background Art

[0002] Polyester cloth is formed by weaving polyester composite yarns in warp and weft. Polyester fiber has good structural strength and shape retention, so polyester cloth is often used to make work clothes for outdoor workers.

[0003] In order to ensure the warmth of outdoor workers during winter work, the thickness of the fabric is often increased to reduce the cold air passing through the fabric. However, as the thickness of the fabric increases, it will affect the normal work of the workers. Therefore, a structure is set to solve the problem of thick thermal insulation fabrics. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a warm polyester cloth, which can improve the overall thermal insulation performance of the cloth through structural settings.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: the thermal insulation polyester cloth includes an inner layer and an outer layer fixedly connected to each other, and the side of the inner layer close to the outer layer is concave inward to form a plurality of thermal insulation grooves, and a thermal insulation sheet that is against the outer layer is fixedly connected in the thermal insulation groove, and the thermal insulation sheet has elastic deformation performance. Thermal insulation fleece is fixedly connected on both sides of the thermal insulation sheet, and the thermal insulation fleece includes a plurality of wool fibers. A plurality of thermal insulation cavities are formed inside the thermal insulation sheet, and the thickness of the thermal insulation sheet is greater than the depth of the thermal insulation groove.

[0006] The utility model is further configured as follows: a plurality of through holes are opened on the thermal insulation sheet, the through holes are communicated with the thermal insulation groove, and the thermal insulation cavity is configured as the through holes.

[0007] The utility model is further configured as follows: the width of the warming groove is greater than the width of the warming sheet.

[0008] The utility model is further configured as follows: the thermal fleece and the thermal sheet are integrally formed, the thermal sheet is woven by thermal yarn, and the thermal yarn is configured as short-fiber yarn.

[0009] The utility model is further configured as follows: the warming yarn is formed by twisting polyester shaped fibers and wool fibers, and the cross-sectional shape of the polyester shaped fibers is circular and hollow.

[0010] The utility model is further configured as follows: the inner layer and the outer layer are both woven by composite yarns, and the composite yarns include a composite yarn core and a composite covering yarn spirally wound on the outer side thereof.

[0011] The utility model is further configured as follows: the composite yarn core is formed by twisting cotton fibers, and the composite covering yarn is formed by twisting polyester fibers.

[0012] To sum up, the utility model has the following beneficial effects: the setting of the thermal insulation groove creates a space between the inner layer and the outer layer for the outside static air to remain. The thermal conductivity of the air is poor, thereby ensuring the overall warmth of the structure. The setting of the through holes increases the content of static air in the thermal insulation sheet, further enhancing the overall warmth of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] The thermal polyester fabric, such as Figure 1 and Figure 2 As shown, it includes an inner layer 1 and an outer layer 2 fixedly connected to each other. The inner layer 1 and the outer layer 2 are sewn together by a sewing machine. The thickness of the fabric is increased by setting a double-layer fabric, thereby slowing down the convection of hot and cold air on both sides of the fabric, thereby ensuring the warmth retention of the fabric. A plurality of warming grooves 3 are formed on the side of the inner layer 1 close to the outer layer 2 by hot pressing with a hot press. The setting of the warming grooves 3 increases the still air retained between the inner layer 1 and the outer layer 2. The thermal conductivity of the air is poor, thereby ensuring the warmth retention of the fabric as a whole.

[0019] like Figure 1 and Figure 2As shown, a thermal sheet 4 is sewn on the inner wall of the thermal groove 3 by a sewing machine, and thermal fleece 5 is fixedly connected to both sides of the thermal sheet 4. The arrangement of the thermal fleece 5 increases the thickness of the thermal sheet 4, further reducing the cold air that passes through the fabric and contacts the user's body surface. On the other hand, the arrangement of the thermal fleece 5 increases the content of static air on both sides of the thermal sheet 4. The thermal fleece 5 includes a number of wool fibers, and the wool fibers are naturally curled, so that they can better store external air. The thickness of the thermal sheet 4 is greater than the depth of the thermal groove 3. Under the action of the thermal sheet 4, the distance between the inner layer 1 and the outer layer 2 is increased, thereby increasing the static air between the inner layer 1 and the outer layer 2. When the fabric is in use, it will be subjected to the pressure exerted on it by the outside world, causing the thermal sheet 4 to be compressed and deformed. When the pressure on the thermal sheet 4 disappears, the thermal sheet 4 will be reset under the action of its own elastic deformation performance, ensuring the stable support of its inner layer 1 and the outer layer 2, and increasing the overall warmth of the fabric through the structural setting.

[0020] like Figure 1 and Figure 2 As shown, a number of through holes 6 are opened along the thickness direction of the thermal insulation sheet 4 by a laser punching machine, and the thermal insulation cavity is set as the through hole 6, which is connected to the thermal insulation groove 3. The width of the thermal insulation groove 3 is greater than the width of the thermal insulation sheet 4. The setting of the through hole 6 and the width of the thermal insulation groove 3 increases the still air inside the thermal insulation sheet 4, thereby reducing the loss of body surface heat and improving the lightweight and warm effect of the fabric. The fabric will be subjected to external pressure during use. After the pressure of the external force on the fabric disappears, the inner layer 1 and the outer layer 2 can return to their original state under the support of the thermal insulation sheet 4, ensuring the fluffy effect of the fabric.

[0021] like Figure 2 As shown, the thermal fleece 5 and the thermal sheet 4 are integrally formed, and the thermal sheet 4 is woven with thermal yarn, which is set as short-fiber yarn. Therefore, the fibers exposed on the outer peripheral wall of the short-fiber yarn enable the thermal sheet 4 to naturally form thermal fleece 5 during weaving, ensuring the stability of the structure during production and use.

[0022] like Figure 2 As shown, the warm yarn is formed by twisting polyester shaped fibers and wool fibers. The cross-sectional shape of the polyester shaped fibers is circular and hollow, thereby increasing the content of static air inside the warm yarn and the warming sheet 4, and enhancing the warmth and comfort of the fabric. The polyester shaped fibers and wool fibers are placed in a cutting machine and cut into short fibers, and then the cut polyester shaped fibers and wool fibers are placed in a cotton blending machine and twisted to form warm yarn.

[0023] like Figure 1 and Figure 3As shown, the inner layer 1 and the outer layer 2 are both woven by composite yarn 7, which includes a composite yarn core 8 and a composite covering yarn 9. The composite yarn core 8 and the composite covering yarn 9 are processed by a mule spinning process to form the composite yarn 7. The composite yarn core 8 is formed by twisting cotton fibers through a twisting machine. There are several cavities inside the cotton fibers, so that the composite yarn 7 can store more still air. The composite covering yarn 9 is formed by twisting polyester fibers through a twisting machine. Polyester fibers have good structural strength and shape retention. The overall durability of the fabric is enhanced by the setting of polyester fibers.

[0024] like Figure 1 - Figure 3 As shown, when the fabric needs to be made, the composite yarn 7 is placed in a shuttle loom and woven to form an inner layer 1 and an outer layer 2. Several thermal insulation grooves 3 are formed along one side of the inner layer 1 by hot pressing using a hot press. The thermal insulation yarn is placed in a shuttle loom and woven to form a thermal insulation layer and thermal insulation fleece 5. Several through holes 6 are opened along the thickness direction of the thermal insulation layer by a laser punching machine. Several thermal insulation sheets 4 are then cut along the thickness direction of the thermal insulation layer by a laser cutting machine. The thermal insulation sheets 4 are sewed into the thermal insulation grooves 3 by a sewing machine. Finally, the inner layer 1 and the outer layer 2 are sewed together by a sewing machine.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
