[0017] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0018] It should be noted that unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be the general meanings understood by those of ordinary skill in the art to which this disclosure belongs.

[0019] To facilitate the understanding of the fibers provided in the embodiments of the present application, the application scenarios will be described first. The fibers provided in the embodiments of the present application are used to prepare fabrics or woven into clothes. However, when the existing fibers are formed into clothes and worn on the human body, their functions are relatively single. Therefore, the embodiments of the present application provide a kind of fiber to improve the effect of users wearing clothes made of the fiber. The following will be described in detail with specific drawings and embodiments.

[0020] Referring to Figure 1 as shown, Figure 1 The schematic structural diagram of the fiber provided in the embodiments of the present application is shown. The fiber provided in the embodiments of the present application includes multiple strands of polyamide filaments 100, and the multiple strands of polyamide filaments 100 are helically wound to form a single fiber. The fiber provided in the embodiments of the present application may further include a core 300, which is located in the middle of the fiber, and the multiple strands of polyamide filaments 100 are helically wound around the core 300. Among them, the cross-section of the core 300 is triangular, and the three sides of the cross-section of the core 300 are concave arc edges 310, so that the surface of the core 300 extending along its axis is a concave surface. When the polyamide filaments 100 are wound around the chip 300, there is a gap between them and the concave surface.

[0021] In addition, the fiber further includes a plurality of microcapsules 200 filled in the gaps between the core 300 and the polyamide filaments 100 and between the polyamide filaments 100. The plurality of microcapsules 200 can be freely dispersed in the gaps formed when the multiple strands of polyamide filaments 100 are wound, and adhere to the polyamide filaments 100 or are located in the space surrounded by the mutual winding of the polyamide filaments 100.

[0022] The microcapsule 200 is a capsule containing camellia extract, which mainly includes a capsule shell and camellia extract filled in the capsule shell, so that the camellia extract can be wrapped by the capsule shell.

[0023] Among them, the camellia extract is rich in various bioactive ingredients such as flavonoids, polyphenols, VE, oleic acid, squalene, phytosterols and nutritional elements such as calcium, potassium, magnesium, manganese, etc. Its extract has a good effect of repairing the skin barrier. Among them, VE is vitamin E, which has an antioxidant effect and can protect skin cells from the damage of free radicals and delay skin aging. Oleic acid is an unsaturated fatty acid, which can moisten the skin and increase the elasticity and softness of the skin. Squalene is a fat-soluble substance with a strong moisturizing effect, which can help the skin retain moisture and improve skin dryness. Phytosterols can regulate the oil secretion of the skin and keep the skin in a balanced state.

[0024] It is understandable that after the microcapsules 200 containing camellia extract are arranged on textiles, during the wearing and washing process, the capsule shell material may be cracked by external forces such as friction and pressure, and the camellia extract may be released, thereby exerting its antioxidant properties.

[0025] When the multiple strands of nylon yarn 100 are wound around the core 300, a gap can be formed between the multiple strands of nylon yarn 100 and the concave surface, thereby accommodating more microcapsules 200. When the above structure is adopted, when the fiber is deformed, the concave surface thereof will also be deformed, thereby better squeezing the microcapsules 200, so that the camellia extract can be better released.

[0026] In the embodiment of the present application, the elasticity of the core 300 is less than that of the nylon yarn 100, so that the core 300 can provide a certain strength support. For example, the material of the core 300 can also be nylon, but the diameter of the core 300 is greater than the diameter of the nylon yarn 100. When the elasticity between the core 300 and the nylon yarn 200 is different, when they are subjected to force, the elastic deformation that occurs is different, so that the nylon yarn 100 and the core 300 can generate relative movement, so that the microcapsules 200 can be squeezed and broken more easily.

[0027] The multiple microcapsules 200 provided in the embodiment of the present application include at least three types of microcapsules with different wall thicknesses. Exemplarily, the microcapsules 200 may include a first microcapsule 230, a second microcapsule 220, and a third microcapsule 210 according to the wall thickness, wherein the thickness of the first microcapsule 230 is less than the thickness of the second microcapsule 220, and the thickness of the second microcapsule 220 is less than the thickness of the third microcapsule 210. When in use, the microcapsules 200 of different thicknesses are subjected to different extrusion forces when broken, so that the clothes made of the fibers can still retain a sufficient number of microcapsules 200 after washing, thereby improving the camellia extract to provide more lasting protection to users.

[0028] It should be understood that the microcapsule 200 provided in the embodiment of the present application is a particle structure of relatively small size, wherein the median particle size of the microcapsule 200 may be 300 nm to 500 nm. Figure 1 and Figure 2 In order to facilitate the illustration of the microcapsule 200, its size is appropriately enlarged for illustration.

[0029] For reference Figure 2 , Figure 2 The schematic diagram of the structure of the nylon yarn is shown. The nylon yarn 100 provided in the embodiment of the present application is provided with a plurality of receiving grooves, which are arranged at intervals along the circumference of the nylon yarn 100 to surround the center line of the nylon yarn 100, and the length direction of each receiving groove is along the length direction of the nylon yarn 100, thereby forming a through groove body. When accommodating the microcapsule 200, part of the microcapsule 200 is accommodated in the receiving groove.Figure 1 It can be seen that when the multi-strand polyamide filaments 100 are wound, the receiving grooves on the polyamide filaments 100 also spiral along with the polyamide filaments 100, so that more space can be formed between adjacent polyamide filaments 100 to accommodate the microcapsules 200, ensuring that more microcapsules 200 can be stored in the formed fibers.

[0030] From the above description, it can be seen that the fiber provided by the embodiment of the present application forms a fiber by winding a multi-strand polyamide filament 100 around a core 300 to enhance the structural strength of the fiber, and microcapsules 200 containing camellia extract are added into the gaps between the polyamide filaments 100 during the winding process. When the fiber adheres to the human body, the microcapsules 200 can be broken by the extrusion force between the fibers to release the camellia extract, which can help users resist the damage of free radicals to the skin, slow down the skin aging speed, and at the same time has a certain effect of moisturizing and nourishing the skin, which is beneficial to skin health and achieves the effect of improving the adhesion between the fiber and the human body.

[0031] In addition, during preparation, the microcapsules 200 provided by the present application can form a capsule shell by the electrostatic interaction between chitosan and sodium tripolyphosphate, providing a protection barrier for the camellia extract. Then, the capsule shell and the solution of the camellia extract are further mixed, so that the shell of the microcapsules 200 interacts with the camellia extract through ion gelation, realizing the effective encapsulation of the camellia extract. Finally, through treatment steps such as vacuum filtration, washing, and drying, high-quality microcapsules 200 containing camellia extract are obtained. The microcapsules 200 in the fiber provided by the embodiment of the present application are prepared by wrapping the camellia with a high-temperature resistant polymer, solving the problems that camellia is insoluble in water, volatile at high temperatures, and not suitable for finishing and processing of textiles.

[0032] And the microcapsules 200 containing camellia extract prepared by the above method can continuously release camellia extract and tea polyphenols, have strong antioxidant functions, can make the skin antioxidant and resist pollution such as ultraviolet rays, dust, fog, and automobile exhaust, and avoid skin problems such as redness, itching, and allergies. The microcapsules 200 containing camellia extract can release tea polyphenols to scavenge free radicals and protect the skin from oxidative damage.

[0033] In an alternative embodiment, the groove walls in the receiving grooves have a relatively high roughness, so that the microcapsules 200 can adhere better to the groove walls of the receiving grooves. Thus, the microcapsules 200 can be more stably accommodated in the fiber.

[0034] To better accommodate the microcapsules 200, when setting the accommodation grooves, the width of each accommodation groove is less than the spacing between any two adjacent accommodation grooves. This ensures that when different fibers are wound, the protrusions formed between the accommodation grooves of one fiber will not insert into the accommodation grooves of another fiber, guaranteeing that there is sufficient space in the accommodation grooves to hold the microcapsules 200.

[0035] In an alternative embodiment, at least one of the multi-strand nylon filaments 100 includes antistatic nylon filaments 110 and ultraviolet-resistant nylon filaments 120, and the antistatic nylon filaments 110 and the ultraviolet-resistant nylon filaments 120 are arranged alternately. As Figure 1 shown in [reference], along the circumferential direction of the fiber, the antistatic nylon filaments 110 and the ultraviolet-resistant nylon filaments 120 are arranged alternately. After the fiber is wound, the fiber can have the functions of antistatic and ultraviolet resistance, which can better improve the wearing effect of the user.

[0036] Refer to Figure 1 simultaneously, as a deformed structure, the sharp corners of the cross-section of the core 300 are rounded arcs, so that the shape of the overall fiber is more rounded, improving the comfort of the clothing made therefrom when worn on the user.

[0037] In an alternative embodiment, the core 300 has a hollow structure with a through triangular channel inside to form a hollow cavity. In this way, the elasticity of the core 300 can be improved, making it easier to deform.

[0038] The embodiments of the present application also provide a fabric, which is formed by weaving the fibers of any one of the above.

[0039] As can be seen from the above description, the fabric provided by the embodiments of the present application is prepared by winding the multi-strand nylon filaments 100 around the core 300 to form fibers, and microcapsules 200 containing camellia extract are added into the gaps between the nylon filaments 100 during the winding process. When the fiber adheres to the human body, the microcapsules 200 can be broken by the extrusion force between the fibers to release the camellia extract, which can help the user resist the damage of free radicals to the skin, slow down the skin aging speed, and at the same time has a certain moisturizing and skin-nourishing effect, which is beneficial to skin health and achieves the effect of improving the adhesion between the fiber and the human body.
