Abstract
Description
Technical Field
[0001] This application relates to the field of flannel, particularly to multifunctional aerogel flannel.
Background Art
[0002] As China's economy develops rapidly and the national economy continues to improve, people have higher requirements in aspects such as clothing, food, housing, and transportation. Especially regarding clothing, with the innovation of fiber material technology, many surprises and conveniences have been brought to people. In particular, flannel materials are widely applied.
[0003] Conventional flannel generally includes a bottom yarn layer and a surface yarn layer. The bottom yarn layer is generally knitted in a mesh shape with polyester as the material, and the surface yarn layer is knitted on the bottom yarn layer and is generally composed of a raised material such as wool.
[0004] In the above related technology, conventional flannel cannot effectively limit the propagation of heat radiation, resulting in an increase in the thermal conductivity of the flannel and a decrease in the heat insulation and heat retention effects of the flannel. As a result, the user experience of the flannel deteriorates.
Summary of the Invention
Problems to be Solved by the Invention
[0005] In order to control the propagation effect of heat radiation by flannel and enhance the heat insulation, heat shielding, and heat retention effects of flannel, this application provides a multifunctional aerogel flannel.
Means for Solving the Problems
[0006] The multifunctional aerogel flannel according to this application adopts the following technical solutions.
[0007] A multi-functional aerogel flannel comprising a bottom yarn layer and a top yarn layer, wherein the top yarn layer is knitted and fixed to the bottom yarn layer, the bottom yarn layer comprises at least aerogel functional yarn, each of which is knitted to form the bottom yarn layer, and the aerogel functional yarn has an insulating effect that limits heat radiation propagation.
[0008] Selectively, the aerogel functional yarn comprises a base material and airgel particles, the airgel particles being formed on the base material.
[0009] Selectively, the air gel particles are uniformly distributed on the surface and inside the substrate.
[0010] The material of the base material can be selected from one or more of polyester fibers, nylon fibers, and viscose rayon fibers.
[0011] The base layer may optionally further include a general-purpose functional yarn, and the general-purpose functional yarn and the aerogel functional yarn are interwoven to form the base layer.
[0012] The material of the general-purpose functional yarn can be selected from one or more of the following: polyester fiber, nylon fiber, and viscose rayon fiber.
[0013] The material of the surface yarn layer is selectable to be one or more of wool fibers, cotton fibers, and polyester fibers.
[0014] The height range of the surface yarn layer is selectable, from 1 mm to 16 mm.
[0015] Selectable weight range for the flannel is 150 g / m². 2 ~600g / m 2 That is the case. [Effects of the Invention]
[0016] As described above, this application has at least one of the following beneficial technical effects. When a user uses textile products such as clothing made with flannel for warmth, the heat emitted from the human body is effectively blocked by the aerogel functional yarn that makes up the bottom layer, and the heat radiation emitted from the human body itself is reflected back towards the human body, thereby retaining the body's heat and effectively suppressing heat conduction from the body to the outside, reducing the thermal conductivity of the flannel. Furthermore, the transmission of cold air from the outside to the body is blocked, further improving the heat retention effect. In addition, because a large amount of still air is present inside the top layer, heat conduction between the body's heat and the outside is further reduced, further improving the heat retention effect of the flannel. This solves the problem that conventional flannel cannot effectively suppress the propagation of heat radiation, resulting in high thermal conductivity and insufficient insulation and heat retention, which worsens the user experience with flannel.

[Figure 2] This is a schematic diagram of the structure of the bottom yarn layer according to an embodiment of the present invention. [Figure 3] Figure 1 shows a schematic diagram of the structure of the aerogel functional yarn according to an embodiment of the present invention. [Figure 4] Figure 2 shows a schematic diagram of the structure of the aerogel functional yarn according to an embodiment of the present invention. [Modes for carrying out the invention]
[0018] The present invention will be described in further detail below with reference to Figures 1-4.
[0019] Embodiments of the present application disclose a multifunctional aerogel flannel. Referring to FIGS. 1 to 4, the multifunctional aerogel flannel includes a bottom yarn layer 1 and a surface yarn layer 2. The surface yarn layer 2 is knitted and fixed to the bottom yarn layer 1, and adopts one or more materials of wool fiber, cotton fiber and polyester fiber. In a preferred embodiment, the material used for the surface yarn layer 2 is wool fiber. Since there is more static air inside the surface yarn layer, the heat preservation effect of the surface yarn layer is improved, and the generation of flannel static electricity is reduced. The height range of the surface yarn layer 2 may be 1 mm to 16 mm. Users can select surface yarn layers 2 with different heights according to the local heat preservation needs and obtain different heat preservation effects. The present application is not limited thereto.
[0020] Referring to FIGS. 1 and 2, the bottom yarn layer 1 includes an aerogel functional yarn 11. The bottom yarn layer 1 is knitted and formed independently by the aerogel functional yarn 11. The bottom yarn layer 1 may further include a general-purpose functional yarn 12. The general-purpose functional yarn 12 and the aerogel functional yarn 11 form the bottom yarn layer 1 by a knitting method such as warp knitting or weft knitting. In a preferred form, the bottom yarn layer 1 is knitted and formed by the general-purpose functional yarn 12 and the aerogel functional yarn 11.
[0021] Referring to FIGS. 1 to 4, in the embodiment of the present application, the aerogel functional yarn 11 is formed by a base material 111 and aerogel particles 112. The aerogel particles 112 are formed on the base material 111. It should be understood that the aerogel particles 112 are aerogels presenting a particle structure. The present application is not limited to the size of the aerogel particles 112. It should also be understood that there is a network structure on the nanometer order inside the aerogel material. It is a typical nanoporous material, formed by the aggregation of colloidal particles or polymers with each other, and is a highly dispersive three-dimensional porous solid material with gas as the dispersion medium. As a result, a large amount of static air exists inside the aerogel, so the aerogel material has the performance of effectively blocking heat conduction. Therefore, the aerogel material exhibits an excellent heat insulation effect and is a relatively ideal heat insulation material.
[0022] In a further embodiment, when the aerogel functional yarn 11 is produced by the airgel particles 112 and the base material 111, since the airgel particles 112 are uniformly distributed on the surface and inside of the base material 111, the aerogel functional yarn 11 can better exert the heat insulation effect of the airgel particles 112, reduce the heat conduction efficiency of the aerogel functional yarn 11, and realize that the aerogel functional yarn 11 has a heat insulation effect that restricts the propagation of heat radiation. The material of the base material 111 adopts one or more of polyester fiber, nylon fiber and viscose rayon fiber. As a preferred embodiment, the material used for the base material 111 is polyester fiber.
[0023] Referring to FIGS. 1 to 4, in the embodiment of the present application, the material of the general-purpose functional yarn 12 adopts one or more of polyester fiber, nylon fiber and viscose rayon fiber. As a preferred embodiment, the material used for the general-purpose functional yarn 12 is polyester fiber.
[0024] Referring to FIGS. 1, 2 and 3, in the embodiment of the present application, the basis weight range of the flannel is 150 g / m 2 ~600 g / m 2 and the flannels with different basis weights have different heat insulation and warming effects. The user can select a flannel with an appropriate basis weight according to the environmental temperature of the location for warming, and the basis weight of the flannel is not limited in the embodiment of the present application.
[0025] Implementation principle of multi-functional aerogel flannel according to the embodiment of the present invention: When a user uses textile products such as clothing made with flannel for heat retention, the amount of heat released from the human body is effectively blocked by the aerogel functional yarn 11 constituting the bottom yarn layer 1, and the heat radiation emitted from the human body itself is reflected back toward the human body, thereby retaining the body's heat, effectively suppressing heat conduction from the body to the outside, and lowering the thermal conductivity of the flannel. Furthermore, the transmission of cold air from the outside to the human body is blocked, further improving the heat retention effect. In addition, since a large amount of still air is present inside the surface yarn layer 2, heat conduction between the body's heat and the outside is further reduced, further improving the heat retention effect of the flannel. This solves the problem that conventional flannel cannot effectively suppress the propagation of heat radiation, resulting in high thermal conductivity and insufficient heat insulation and heat retention effects, which worsens the user experience of using flannel.
[0026] All of the above are preferred embodiments of the present application, and in order not to limit the scope of protection of the present application, any equivalent changes made based on the structure, shape, and principle of the present application should be included within the scope of protection of the present application.
