Description

Technical Field

[0001] This utility model relates to a water-resistant functional fabric that is antibacterial and UV-resistant, and more particularly to a functional fabric that is water-resistant and colorfast, and also has antibacterial and UV-resistant functions. Background Technology

[0002] Fabric fibers can generally be divided into long fibers (such as polyester and acrylic fibers) and short fibers (such as wool, cotton, and natural silk). Most short fiber materials are fluffy, soft, and elastic. Due to the larger gaps between short fiber molecules, although dye molecules can easily penetrate into the gaps between short fiber molecules during dyeing, they can also easily fall off from these larger gaps. Therefore, various adhesives are often added to short fiber fabrics during the dyeing process to assist in dyeing, allowing the dye molecules to adhere and bind between the short fiber molecules. However, during use, these adhesives are easily lost during washing, causing the dye molecules to fall off and the fabric to fade.

[0003] Furthermore, short fiber materials have a low temperature tolerance (around 100°C), making it difficult to withstand high processing temperatures during processing. Even if dye molecules can penetrate into the gaps between short fiber molecules at lower temperatures, they are easily separated from each short fiber molecule during long-term use, such as during heating, washing, or sun exposure, resulting in application deficiencies.

[0004] Most long-fiber materials are strong, not easy to break, smooth and shiny, and have high elasticity and poor heat retention, making them more suitable as the main material for general cooling functional clothing. However, because the gaps between the molecules of long-fiber materials are small, the dye molecules do not easily penetrate into the gaps between the long-fiber molecules during dyeing. Not only does it require a higher processing temperature during dyeing, but it also requires related processing (such as extrusion) procedures to allow the dye to penetrate and adhere to the gaps between the long-fiber molecules, making long-fiber fabrics more difficult to dye.

[0005] Currently, most common processing of UV-resistant functional fabrics involves weaving a blend of polyester fibers and elastic yarns. After washing to remove surface impurities, the fabric is bleached with a fluorescent agent, then coated with a fluorescent colorant. After drying to remove formaldehyde and fix color fastness, a fluorescent protective layer is formed on the fabric surface, completing the processing of the UV-resistant (sunscreen) functional fabric substrate. However, after repeated washing, the fluorescent protective layer on the fabric surface will gradually lose its fluorescent components, reducing the sun protection effect.

[0006] In view of the aforementioned shortcomings of conventional functional fabrics, the inventor researched ways to improve upon these shortcomings, and finally this utility model was created. Utility Model Content

[0007] The main objective of this invention is to provide an antibacterial and UV-resistant washable functional fabric, comprising: a fabric woven from microfibers such as polyester and spandex fibers; a washable dyeing layer, which is permeated and dyed into the fabric, wherein each dyeing solution in the washable dyeing layer can, during bonding, allow the dye particles of the dyeing solution to penetrate into each microfiber of the fabric; and a washable functional layer, which is bonded to the washable dyeing layer at high temperature, containing a UV-absorbing agent capable of isolating and absorbing ultraviolet rays, and an antibacterial agent capable of killing bacteria. After the washable functional layer is high-temperature set, the UV-absorbing agent and the antibacterial agent can penetrate into each microfiber of the fabric and the washable dyeing layer, forming an adherent state that is not easily washed off, and making the washable functional layer, the washable dyeing layer, and the fabric tightly bonded to form a washable functional fabric. This effectively improves the shortcomings of traditional long-fiber fabrics, such as difficulty in dyeing and easy fading.

[0008] Another objective of this invention is to provide an antibacterial and UV-resistant washable functional fabric, wherein the washable functional layer is bonded to the washable dyed layer after being set at high temperature. The UV-absorbing auxiliaries and antibacterial auxiliaries can penetrate and stably adhere to each of the microfibers of the fabric, forming a combination that is not easily washed off, which can effectively extend the service life of the washable functional layer.

[0009] To achieve the above objectives and effects, the technical means adopted by this utility model are as follows: This utility model provides an antibacterial and UV-resistant washable functional fabric, characterized in that it comprises:

[0012] A washable functional layer is formed by fixing a functional liquid with ultraviolet absorption and antibacterial properties between the fabric and the washable dyed layer. The functional liquid penetrates and binds at least partially between the microfibers of the fabric and the washable dyed layer, so that the fabric, the washable dyed layer and the washable functional layer are combined to form a functional fabric that is not easily washed off and is antibacterial and anti-ultraviolet.

Detailed Implementation

[0026] Please refer to Figures 1 to 6 As shown, the structure of the functional fabric A of this utility model mainly includes: fabric 1, a washable dyeing layer 2, and a washable functional layer 3; wherein the fabric 1 is mainly a high-elasticity knitted fabric made of approximately 85% ultrafine polyester fiber (Polyester, a synthetic fiber) and approximately 15% spandex (Spandex, an elastic fiber) through warp and weft weaving; microscopically, the fabric 1 is composed of ultrafine fibers 10 formed by densely arranged numerous ultrafine fiber molecules 100 through warp and weft weaving (e.g. Figure 1 and Figure 2 (As shown).

[0027] The washable dyeing layer 2 contains a number of dye particles 20, which can penetrate and be bound between the microfiber molecules 100 of each microfiber 10 of the fabric 1, forming a fixed state that is not easily removed by washing, thus initially achieving the effect of not being easy to fade or discolor.

[0028] The washable functional layer 3 is composed of a mixture of auxiliaries containing ultraviolet absorbing agent 31 and multiple antibacterial agents 32. The ultraviolet absorbing agent 31 and antibacterial agents 32 are respectively at least partially penetrated between each microfiber 10 of the fabric 1 and the washable dyed layer 2, thereby connecting the washable dyed layer 2 to form a fixed state that is not easily washed off.

[0029] Please refer to Figure 3 As shown, a feasible processing flow that may be used to manufacture the functional fabric of this case is clear, which includes: a "pre-weaving treatment" step S11, a "wash-resistant dyeing layer processing" step S12, a "wash-resistant functional layer coating processing" step S13, and a "setting" step S14; wherein:

[0030] The "fabric pretreatment" step S11 involves immersing the fabric, which is woven from microfiber and spandex, in an emulsion and refining it by soaking in circulating hot water to remove impurities and form fabric 1 (semi-bleached fabric). Then, high temperature is used to stabilize the size and shape of fabric 1 to prevent it from deforming due to subsequent high-temperature baking.

[0031] The "wash-resistant dyeing layer processing" S12 step involves immersing the fabric 1, which has undergone the "pre-weaving treatment" S11 step, in a slightly acidic pH dyeing solution. After high-temperature, high-pressure dyeing, the dye particles 20 in the dyeing solution penetrate between the microfiber molecules 100 of the fabric 1. The pH of the fabric 1 is then neutralized with alkali and dried for setting. This allows the dye particles 20 to coat and penetrate between and around the microfiber molecules 100 trapped within the fabric 1 (e.g., ...). Figure 4 A washable dyeing layer 2 is formed on the fabric 1. Since each dye particle 20 can be clamped by each microfiber molecule 100 and is not easy to fall off, the color fastness of the washable dyeing layer 2 on the fabric 1 can be effectively stabilized, so that the fabric 1 and the washable dyeing layer 2 are tightly combined to form a semi-finished substrate B.

[0032] In this embodiment, the dyeing solution is specifically maintained at a pH of 4.0, and the fabric 1 is dyed at a high temperature and high pressure of 130°C for 40 minutes. This allows the dyeing solution to penetrate at least partially into the microfibers 10 of the fabric 1, and enables each dye particle 20 to penetrate evenly between each microfiber molecule 100. After the dyeing process, the fabric 1 is then soaked in a liquid alkali (Sodium hydroxide) with a pH of 11-12 at approximately 85°C for 20 minutes to neutralize the acidic pH value during the dyeing process. This allows the pH value of the semi-finished substrate B, which is composed of the fabric 1 and the washable dyeing layer 2, to be controlled and maintained within the range of pH 5-7, which is close to the pH value of human skin. This also ensures that the washable dyeing layer 2 of the semi-finished substrate B effectively maintains stable color fastness and is washable without easily fading.

[0033] The "wash-resistant functional layer coating process" S13 involves coating the surface of the semi-finished substrate B and the wash-resistant dyeing layer 2 with a functional liquid 30 containing ultraviolet absorbing agent 31 and antibacterial agent 32 (e.g., ...). Figure 5 ).

[0034] The "setting" step S14 involves heating and baking the semi-finished substrate B, which has the functional liquid 30 coated on its surface, at a temperature above 150°C. This causes the molecular chains of the microfibers 10 in the fabric 1 to expand at high temperatures, allowing the ultraviolet-absorbing agent 31 and the antibacterial agent 32 in the functional liquid 30 to evenly penetrate and form microfibers 10 and the wash-resistant dyeing layer 2 near the surface of the fabric 1. The dye particles 20 of the aforementioned wash-resistant dyeing layer 2 then penetrate into each microfiber 10 during this process. The ultraviolet-absorbing agent 31 and antibacterial agent 32 penetrate deeply into the microfiber molecules 100 at the center; then, after high-temperature setting, the ultraviolet-absorbing agent 31 and antibacterial agent 32 can be evenly penetrated into each microfiber 10, allowing each microfiber 10 to saturate with the ultraviolet-absorbing agent 31 and antibacterial agent 32. After cooling, as the temperature decreases, the molecules of the ultraviolet-absorbing agent 31 and antibacterial agent 32 can be fully embedded between each microfiber molecule 100 of the fabric 1, and at least partially interlinked in the aforementioned washable dyeing layer 2 (e.g., Figure 6 A washable functional layer 3 is formed, so that the semi-finished substrate B (fabric 1, washable dyeing layer 2) and the washable functional layer 3 are combined to form a washable functional fabric A with sun protection and antibacterial properties.

[0035] In this embodiment, the ultraviolet absorbing agent 31 can be an anti-UV agent (UV-220) with an ultraviolet protection factor of UV-50+ (DWR Anti-Ultraviolet 50+). It is used to bond with the semi-finished substrate B. It is doubly crosslinked in the fabric by the microfiber 10 and the washable dyeing layer 2 and is insoluble in water. It can convert ultraviolet rays into heat or release low-energy radiation energy to reduce the transmittance of ultraviolet rays, increase the reflectivity and absorption rate of the functional fabric A to ultraviolet rays, reduce fading caused by sun exposure, and thus effectively extend the service life of the functional fabric A.

[0036] The antibacterial additive 32 is a silver ion antibacterial agent used to combine with the semi-finished substrate B. It is doubly crosslinked in the fabric by the microfiber 10 and the washable dyeing layer 2 and is insoluble in water. It is active but not migratory. When bacteria on the human body surface are transferred to the functional fabric A through the evaporation of sweat, the silver ions in the silver ion antibacterial agent can pierce the cell DNA of the bacteria, preventing the cells from metabolizing and reproducing until they die. This inhibits the formation of viral proteins, preventing them from relying on the host to reproduce, thereby achieving a sterilization effect.

[0037] The functional fabric A product with the above-mentioned structure of this utility model has been tested by the credible Taiwan Inspection and Testing Technology Co., Ltd. (SGS) (results are shown in Annexes 1 and 2). After 50 washes, the sterilization rate of functional fabric A can still reach >99.9% against Staphylococcus aureus (protecting the skin), 99.6% against Klebsiella pneumoniae (protecting the respiratory system), and >99.9% against Escherichia coli (protecting the digestive system). Moreover, its UV50+ resistance can reach a UV-A blocking rate of 99.96% and a UV-B blocking rate of 99.98%. This is sufficient to prove that functional fabric A can still maintain excellent antibacterial and UV-resistant effects after multiple washes, and it does have the characteristics of being washable, antibacterial, and UV resistant.

[0038] In summary, the structural design of the antibacterial and UV-resistant washable functional fabric of this utility model can indeed enable the fabric to achieve colorfastness after washing, while also possessing antibacterial and UV-resistant effects. The above description is only an illustration of the preferred embodiment of this utility model. Any variations, modifications, alterations, or equivalent substitutions that extend from the technical means and scope of this utility model should also fall within the scope of this utility model's patent application.
