Description

Technical Field

[0001] This invention belongs to the field of functional fabric technology, specifically relating to a functional fabric with high color fastness to ultraviolet radiation. Background Technology

[0002] With the increasing demand for outdoor work, sports, and daily protection, the UV protection performance of functional fabrics has become one of the key evaluation indicators. Ultraviolet (UV) rays can penetrate ordinary textile materials, leading to sunburn, photoaging, and even increasing the risk of skin cancer. Therefore, improving the UV protection capability of fabrics has significant health and practical implications. Traditional UV protection treatments mainly include two categories: chemical finishing and physical structural design. Chemical methods achieve protection using UV absorbers or shielding agents, but these auxiliaries are easily shed during washing, friction, and sun exposure, leading not only to a decrease in protective performance but also potentially causing skin sensitivity or environmental pollution problems.

[0003] To overcome the limitations of chemical methods, physical UV protection technology has gradually become a research focus. Its core idea is to block or reflect ultraviolet (UV) rays through fabric structural design, avoiding the use of chemical additives, thus balancing environmental friendliness, safety, and long-lasting effectiveness. Existing physical UV protection methods mainly include the following: First, using multi-layered, dense structures to increase the number of fabric layers and block UV penetration. However, this method often results in heavy, stiff fabrics, severely affecting wearing comfort and freedom of movement. Second, developing smooth-surfaced fabrics that use highly reflective fibers or coatings to reflect UV rays. However, the protective effect of such materials is significantly angle-dependent, and it is difficult to completely seal the tiny gaps between fibers, leaving loopholes for UV penetration.

[0004] To address these shortcomings, composite structural designs have emerged in recent years. These designs combine a high-density inner layer with a thin outer layer, and incorporate air layers between the layers to further enhance UV absorption and refraction. While this structure improves UV resistance to some extent, it still suffers from two significant drawbacks: First, the fabric surface lacks a protective mechanism for colors and coatings, making it prone to color distortion and fading after prolonged sun exposure, sweat, or frequent washing, affecting aesthetics and functional durability. Second, the air layer structure lacks morphological stability; in actual use, it is easily compressed and wrinkled due to pressure, bending, or wear deformation, causing the intended optical protection structure to fail and reducing UV blocking capability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a functional fabric with high color fastness to ultraviolet radiation. It can achieve stable and high-level ultraviolet protection while maintaining lightweight, softness, and wearing comfort, and at the same time ensure color fastness and structural durability to meet the practical needs of high-intensity outdoor use and repeated washing.

[0006] This invention is achieved through the following technical solution:

[0007] A functional fabric with high color fastness to ultraviolet radiation protection comprises, from bottom to top, a base layer, a protective mechanism, and a surface layer; the protective mechanism is fixedly connected to the top of the base layer to block ultraviolet rays and protect the color stability of the fabric; splicing mechanisms are fixedly connected to the outer perimeter of the base layer for splicing multiple different base layers; the protective mechanism is fixed between the base layer and the surface layer through the splicing mechanisms.

[0008] The protective mechanism comprises, from bottom to top, a connecting layer, a cellular component, a coloring layer, and a diffuse reflection layer, with the connecting layer fixedly connected to the top of the base layer.

[0009] Preferably, the honeycomb assembly consists of a soft honeycomb layer and supporting pads. The soft honeycomb layer is fixedly connected to the top wall of the connecting layer, and multiple supporting pads are fixedly arranged at equal intervals inside the honeycomb holes of the soft honeycomb layer.

[0010] Preferably, the splicing mechanism includes a splicing base, which is fixedly connected to the outer wall of the base layer. Multiple sub-fastener assemblies and female fastener assemblies are equidistantly fixed on adjacent sides of the outer wall of the splicing base. The sub-fastener assemblies are located on the right and rear sides of the outer wall of the splicing base, and the female fastener assemblies are located on the left and front sides of the outer wall of the splicing base. The sub-fastener assemblies and female fastener assemblies are connected in a cooperative manner.

[0011] Preferably, the sub-fastener assembly includes a sub-fastener base, which is fixedly connected to the right and rear sides of the outer wall of the splicing base. A knob is rotatably connected inside the sub-fastener base, and a T-shaped pin is fixedly connected to the end of the knob.

[0012] The female buckle assembly includes a female buckle base, which is fixedly connected to the left and front sides of the outer wall of the splicing base, and a locking piece is fixedly connected to the middle of the inner wall of the female buckle base.

[0013] Preferably, the locking piece has a square hole in the middle, and the square hole is nested and connected with the T-shaped pin.

[0014] Preferably, the inner wall of the female buckle base is provided with an internal thread, and the bottom of the outer wall of the knob is provided with an external thread, and the knob is threadedly connected to the female buckle base.

[0015] Preferably, the outer wall of the knob has anti-slip texture in the middle.

[0016] Preferably, a surface layer is fixedly connected to the top of the diffuse reflection layer, and the surface layer is disposed on the inner side of the splicing base.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) In the functional fabric of the present invention, the connecting layer of the protective mechanism connects the base layer and other protective layers. The honeycomb assembly consists of a soft honeycomb layer and a support pad. The cavity retains air to promote ultraviolet absorption and refraction. The support pad serves both support and sealing. A coloring layer and a diffuse reflection layer cover the honeycomb assembly. The diffuse reflection layer diffusely reflects light to reduce direct radiation, forming a physical protective layer that protects the coating and improves color fastness. This protective mechanism utilizes multi-layer reflection and refraction to reduce direct ultraviolet radiation, solving the problems of lack of color and protection, unstable air layer morphology, and inability to guarantee ultraviolet resistance in the prior art, thus improving color fastness and ultraviolet resistance.

[0019] (2) In the functional fabric of the present invention, the splicing base of the splicing mechanism protects the edge of the protective mechanism. The male and female fastener assemblies can be spliced ​​with different base layers and protective mechanisms as needed. During splicing, the T-shaped pin passes through the locking piece and enters the interior of the female fastener base. Rotating the knob drives the T-shaped pin to rotate inside the female fastener base. As the angle changes, the T-shaped pin is locked in the cavity between the female fastener base and the locking piece. The threads on the male and female fastener bases ensure that they are tightly connected and not loosened by external force. This splicing mechanism can expand the material area as needed and is easy to disassemble. Attached Figure Description

[0028] Example 1

[0029] A functional fabric with high colorfastness to UV radiation, such as Figure 1-3 As shown, from bottom to top, the structure includes a base layer 1, a protective mechanism 2, and a surface layer 6. Specifically, the base layer 1 is located at the bottom of the overall structure, below all other protective layers. The protective mechanism 2 is fixedly connected to the top of the base layer 1 to block ultraviolet rays and protect the color stability of the fabric. Splicing mechanisms 3 are fixedly connected to the outer perimeter of the base layer 1 for splicing multiple different base layers 1. The protective mechanism 2 is fixed between the base layer 1 and the surface layer 6 via the splicing mechanisms 3.

[0030] like Figure 1 As shown, the protective mechanism 2 includes, from bottom to top, a connecting layer 201, a honeycomb assembly 202, a coloring layer 204, and a diffuse reflection layer 203. The connecting layer 201 is fixedly connected to the top of the base layer 1, and the top of the diffuse reflection layer 203 is fixedly connected to the surface layer 6. Specifically, the connecting layer 201 is attached to the upper surface of the base layer 1. The bottom of the connecting layer 201 is connected to the base layer 1, and its top is connected to other protective layers, thus connecting the base layer 1 with other protective layers. The top of the connecting layer 201 first contacts the honeycomb assembly 202. The upper surface of the honeycomb assembly 202 is covered with the coloring layer 204. The bottom of the coloring layer 204 is connected to the honeycomb assembly 202, and its top is connected to the diffuse reflection layer 203, thus connecting the honeycomb assembly 202 and the diffuse reflection layer 203. The coloring layer 204 also serves as the primary location for coloring treatment. The surface of the diffuse reflection layer 203 has a wavy shape. Through the physical method of diffuse reflection, the light that shines on the surface is dispersed and emitted in multiple other directions, reducing the intensity of direct light. At the same time, the diffuse reflection layer 203 is attached to the surface of the coloring layer 204 to form a physical protective layer, which isolates external friction and collision, thereby protecting the paint on the surface of the coloring layer 204 and improving the color fastness of the paint.

[0031] like Figure 1As shown, the honeycomb assembly 202 is composed of a soft honeycomb layer 2021 and support pads 2022. The soft honeycomb layer 2021 is fixedly connected to the top wall of the connecting layer 201, and multiple support pads 2022 are fixedly arranged at equal intervals inside the honeycomb holes of the soft honeycomb layer 2021. Specifically, the honeycomb module 202 is composed of a flexible honeycomb layer 2021 and a support pad 2022 filled inside it. Each unit of the flexible honeycomb layer 2021 is a hollow hexagonal prism. Multiple identical hexagonal prism units are connected to each other to form a complete honeycomb layer structure (i.e., the flexible honeycomb layer 2021). Air is retained inside the cavity of each hexagonal prism. The properties of air promote the absorption and refraction of ultraviolet rays. The support pad 2022 has both supporting and sealing functions. While keeping the hollow structure of the flexible honeycomb layer 2021 from collapsing, it divides the inside of the honeycomb module 202 into multiple independent cavities that are not interconnected, minimizing air loss and retaining internal air to ensure the efficiency of ultraviolet refraction and absorption.

[0032] The protective mechanism 2 utilizes multi-layer reflection and refraction to reduce direct ultraviolet radiation, and adds a color protection layer to the outer layer. This solves the problems in the prior art where the material layer surface lacks protection for color and coating, the material color is easily distorted by external environmental erosion, the air layer morphology lacks stable control, and the UV resistance performance cannot be guaranteed. It improves color fastness and UV resistance.

[0033] like Figure 2-4 As shown, the splicing mechanism 3 includes a splicing base 301, which is fixedly connected to the outer wall of the base layer 1. The surface layer 6 is disposed on the inner side of the splicing base 301. Multiple sub-fastener components 302 and female fastener components 303 are equidistantly fixed on adjacent sides of the outer wall of the splicing base 301. The sub-fastener components 302 are located on the right and rear sides of the outer wall of the splicing base 301, and the female fastener components 303 are located on the left and front sides of the outer wall of the splicing base 301. The sub-fastener components 302 and female fastener components 303 can be spliced ​​together to form a whole. Specifically, the splicing base 301 is made of a material that is harder than the base layer 1, and it wraps around the edge of the base layer 1 to protect the edges of the protective layers above the base layer 1 from wear. The sub-fastener components 302 and female fastener components 303 cooperate to splice and combine different base layers 1 and corresponding protective mechanisms 2 together.

[0034] like Figure 3 , 5 As shown, the sub-fastener assembly 302 includes a sub-fastener base 3021, which is fixedly connected to the right and rear sides of the outer wall of the splicing base 301. A knob 3022 is rotatably connected inside the sub-fastener base 3021, and a T-shaped pin 3023 is fixedly connected to the end of the knob 3022.

[0035] like Figure 3 , 5 As shown, the female buckle assembly 303 includes a female buckle base 3031, which is fixedly connected to the left and front sides of the outer wall of the splicing base 301. A locking piece 3032 is fixedly connected to the middle of the inner wall of the female buckle base 3031.

[0036] like Figure 5 As shown, the locking piece 3032 has a square hole 5 in its center, which is nested and connected to the T-shaped pin 3023. The inner wall of the female buckle base 3031 has an internal thread 7, and the bottom of the outer wall of the knob 3022 has an external thread 8. The knob 3022 is threadedly connected to the female buckle base 3031. The outer wall of the knob 3022 has anti-slip texture 4 in its center for tightening the knob 3022.

[0037] Specifically, the male buckle assembly 302 is fixedly connected to one side surface of the splicing base 301 via the male buckle base 3021, and the female buckle assembly 303 is fixedly connected to the other side surface of the splicing base 301 via the female buckle base 3031. During splicing, the knob 3022 is aligned with the entrance of the female buckle base 3031 and inserted into the female buckle base 3031. The T-shaped pin 3023 follows the knob 3022 through the through hole of the locking piece 3032 into the internal space of the female buckle base 3031. At this time, the knob 3022 is turned by hand. 22. The T-shaped pin 3023 rotates around the axis inside the female buckle base 3031 via the connecting shaft. As the rotation angle increases, the lateral portion of the T-shaped pin 3023 is locked in the cavity between the inner wall of the female buckle base 3031 and the surface of the locking piece 3032, thus achieving fixation. The external threads 8 distributed on the bottom of the outer wall of the knob 3022 and the internal threads 7 distributed on the inner side of the female buckle base 3031 mesh with each other, allowing them to be tightly connected and preventing relative rotation or loosening when subjected to external force. The shape of the square hole 5 matches the shape of the T-shaped pin 3023, allowing the T-shaped pin 3023 to pass through. At the same time, its rotation can lock the position of the T-shaped pin 3023. The female buckle base 3021 is threadedly connected to the female buckle base 3031 through the internal threads 7 and the external threads 8, ensuring the precision of the installation.

[0038] The splicing mechanism 3 can expand the material area according to actual needs and is easy to disassemble.
