A light-absorbing and heat-generating fabric and its manufacturing process

Abstract

A light-absorbing and heat-generating fabric and its manufacturing process are disclosed, belonging to the field of fabrics. Its structure includes a multi-layered fabric body, comprising an outer layer, an inner layer, and a middle layer. The middle layer is located between the outer and inner layers. The yarns of the middle layer of the light-absorbing and heat-generating fabric contain minerals, which effectively absorb sunlight and artificial light energy and convert them into heat energy, raising the temperature of the fabric. The outer, inner, and middle layers form an isolation structure through polyester filaments. Each yarn contains air, forming an air protective layer to lock in heat loss, significantly improving the heat generation and heat preservation performance, allowing the wearer's skin to feel the heat more directly.

Description

Technical Field

[0001] This invention relates to a light-absorbing and heat-generating fabric and its manufacturing process, belonging to the field of fabrics. Background Technology

[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly influences the color and shape of the garment. Current methods to improve the insulation performance of fabrics involve changing the material of the yarn; however, the improvement in insulation performance is often not significant, and the wearer's skin cannot easily perceive any change or improvement in performance. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a light-absorbing and heat-generating fabric and its manufacturing process, thereby solving the problem that existing fabrics, in order to improve their heat retention performance, often use changes in the yarn material, but the improvement in heat retention performance is often not significant, and the wearer's skin cannot easily feel the change or improvement in performance.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a light-absorbing and heat-generating fabric, the structure of which includes a multi-layered fabric body, the multi-layered fabric body including a surface layer, an inner layer and a middle layer, the middle layer being disposed between the surface layer and the inner layer, the middle layer having a mesh structure, with polyester filaments woven into the mesh openings, the upper and lower ends of the polyester filaments being respectively connected to the surface layer and the inner layer, the middle layer including a first positioning mesh, a mineral heating mesh and a second positioning mesh, the mineral heating mesh being disposed between the first positioning mesh and the second positioning mesh.

[0005] Furthermore, the outer surface is coated with a semi-matte paint.

[0006] Furthermore, the outer and inner layers are made of any one of the following materials: pure cotton, carbon fiber, graphene, or moisture-absorbing and heat-generating fibers.

[0007] Furthermore, the first positioning mesh, the mineral heating mesh, and the second positioning mesh are all made of polyester yarn by a winding and weaving method.

[0008] Furthermore, the mineral heating mesh is connected to the first positioning mesh and the second positioning mesh by adhesive bonding.

[0009] Furthermore, the yarns of the first and second positioning meshes are extruded and shaped to make their cross-sections semi-circular.

[0010] Furthermore, the intermediate layer is connected to the surface layer and the inner layer by any one of the following methods: sewing, hot pressing, or adhesive bonding.

[0011] Further, the manufacturing process of the light-absorbing and heat-generating fabric includes the following: Step S1, firstly, weave the outer layer and inner layer separately; Step S2, then use a special winding and weaving mold to make the middle layer. The winding and weaving mold includes a mold base, and the mold base is provided with positioning slots. The top edge of the positioning slot is provided with multiple winding posts spaced apart. The winding post includes a column body and an injection joint. The injection joint is located at the upper end of the column body. The outer wall of the column body is provided with three annular positioning grooves from top to bottom. The three annular positioning grooves are respectively used to position the yarns of the first positioning mesh, the mineral heating mesh, and the second positioning mesh. There is an injection outlet between every two annular positioning grooves that communicates with the injection joint. The bottom surface of the positioning slot is provided with a hot air positioning machine with the blowing end facing upward; Step S3, through the column body and annular positioning grooves... The positioning grooves are used to weave the second positioning mesh, the mineral heating mesh, and the first positioning mesh from bottom to top using a winding and weaving mold. During the winding and weaving process, mineral-containing glue is injected into the glue injection joint through the glue injection pipe. The glue outlet outputs glue and evenly applies it to the mineral heating mesh as the winding work progresses. As the mineral heating mesh comes into contact with the first and second positioning meshes, they are bonded together. Finally, a hot air positioning machine outputs hot air to the prepared intermediate layer for shaping. In step S4, the intermediate layer is placed between the surface layer and the inner layer. After polyester yarn pillars supporting and positioning the intermediate layer are woven into the surface layer and the inner layer, the surface layer, the inner layer, and the intermediate layer are fixed by hot pressing, thus completing the preparation of the light-absorbing and heating fabric.

[0012] Furthermore, the mineral is any one of quartz, zeolite, or rock wool.

[0013] The beneficial effects of this invention are: the middle layer yarn of the light-absorbing and heat-generating fabric contains minerals, which effectively absorb sunlight and artificial light energy and convert them into heat energy, raising the temperature of the fabric. The polyester filaments form an isolation structure between the outer layer, inner layer and middle layer. Each yarn contains air, forming an air protective layer to lock in heat loss, greatly improving the heat generation and heat preservation performance, and allowing the wearer's skin to feel the heat more directly.

[0025] To improve the stability of the connection, the mineral heating mesh 1032 is connected to the first positioning mesh 1031 and the second positioning mesh 1033 by adhesive bonding.

[0026] In order to allow the adhesive on the mineral heating mesh 1032 to make a larger contact area with the first positioning mesh 1031 and the second positioning mesh 1033, the yarns of the first positioning mesh 1031 and the second positioning mesh 1033 are extruded and shaped so that their cross-sections are semi-circular.

[0027] The intermediate layer 103 is connected to the surface layer 101 and the inner layer 102 by any one of the following methods: sewing, hot pressing or adhesive bonding, with sewing being the preferred method.

[0028] The manufacturing process of the light-absorbing and heat-generating fabric includes the following steps: Step S1, firstly, the outer layer 101 and the inner layer 102 are woven separately; Step S2, then, the middle layer 103 is made using a special winding and weaving mold.

During the winding process, mineral-containing glue is injected into the glue injection joint 402 through the glue injection pipe, and glue is output from the glue outlet 404. As the winding work progresses, the glue is evenly applied to the mineral heating mesh 1032. As the mineral heating mesh 1032 comes into contact with the first positioning mesh 1031 and the second positioning mesh 1033, they bond together. Then, hot air is output to the prepared intermediate layer 103 through the hot air positioning machine 5 for shaping; in step S4, the intermediate layer 103 is placed between the surface layer 101 and the inner layer 102. After polyester yarn pillars 104 supporting and positioning the intermediate layer 103 are woven into the surface layer 101 and the inner layer 102, the surface layer 101, the inner layer 102 and the intermediate layer 103 are fixed by hot pressing, and the light-absorbing and heat-generating fabric is finally prepared.
