Description

Colored antibacterial fabric and manufacturing method thereof
Technical Field
The invention relates to the field of functional fiber fabrics, in particular to a colored fabric with an antibacterial function and a manufacturing method thereof.
Background
Since 2020, the sudden new crown epidemic situation undoubtedly deepens the attention of people on health and environmental protection, the idea of green and health will go deeper into the mind, the social environmental awareness and the health consumption become a trend, along with the improvement of the life and health cognition of consumers, the habit of health protection consumption will become new fashion, and various textiles with antibacterial effect for protection, disinfection, sanitation and the like will emerge endlessly, and meet the new physiological and psychological needs of consumers.
Currently, there are several ways in which textiles can exert antimicrobial functions. The first method is to treat the textile by using organic antibacterial agents such as quaternary ammonium salts, organic metals and the like, but the organic antibacterial agents have the problems of toxicity, poor heat resistance, easy generation of microbial drug resistance and the like. The second is that silver fiber or nano silver is utilized for antibiosis, for example, the nano silver fiber is woven into the fabric, and the fabric of the nano silver fiber gradually changes color in the using process and is not washable; or silver ions are added into the fiber, but the fiber has the defect of being not washable, the antibacterial property of the fiber is gradually weakened along with the increase of the washing times and the use time, and the fiber is not suitable for industrial use and taking and belongs to a disposable antibacterial product. The nano silver added in the two modes is not easy to control the dosage, and the problem of excessive use of the nano silver exists, and researches show that the excessive nano silver particles can have the problem of biological safety.
201810654518.5, 201910601301.2, 201910594850.1, et al, describe the use of vacuum deposition to color fabrics by depositing a film on the surface of the fabric, wherein the fabric has an antimicrobial effect when Ag is present in the film. Some researchers in the prior art use magnetron sputtering in laboratories to realize the antibacterial function of textiles, for example, patent application 201310676663.0 describes that a copper film is sputtered on the surface of a textile and then a zinc oxide film is sputtered on the surface of the textile to form a copper/zinc oxide composite film, so as to realize the antibacterial effect, but the document does not describe the process of sputtering the film for realizing coloring. For another example, according to the preparation method described in the' 201711425172.3 patent application, the textile is first dipped in the silver metavanadate system solution having antibacterial function, and then sputtered with zinc oxide, wherein the zinc oxide is used to reinforce the combination of the silver metavanadate system and the textile to enhance the antibacterial effect.
The antibacterial agent and the excessive nano silver in the prior art have safety problems, and the antibacterial effect of the textile is gradually weakened after the textile is washed. Therefore, it is necessary to develop and design more new film layers to achieve the coloring and antibacterial effects of textiles without affecting the color of the textiles and considering the factors of safety, difficulty of production process, cost, etc.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a novel colored antibacterial fabric and a manufacturing method thereof in order to overcome the defects of poor biological safety, poor fiber washability and the like of an antibacterial agent or an antibacterial film layer.
In order to achieve the above purpose, the invention provides a manufacturing method of a colored fabric with an antibacterial function, which comprises the following steps:
depositing at least one composite film layer on at least one surface of the fiber fabric by a vacuum deposition method, wherein:
the composite film layer comprises a color-generating layer and an antibacterial layer, and the color of the fabric is derived from the color-generating layer or derived from the color-generating layer and the antibacterial layer;
or the composite film layer comprises an antibacterial layer, and the color of the fabric is derived from the antibacterial layer;
the antibacterial film layer contains at least one of Ag element, Cu element, Ti element, Zn element or stainless steel;
and when each layer of the composite film layer is deposited, continuously introducing working gas, wherein the working gas comprises argon and/or nitrogen and/or oxygen.
In a series of past applications of the applicant, attempts have been made to deposit a film layer of metal, alloy, metal oxide, metal nitride, metal oxynitride, metal carbide, etc. on the surface of a fabric by vacuum deposition, and the fabric is colored by design combination, for example, patent applications 201810654518.5, 201910601301.2, 201910594850.1, etc. all describe the same technical method, except that the design composition of the film layer, that is, the fabric with different colors or different functions can be realized by the design of the film layer.
In order to meet the antibacterial requirement of textiles, the film layer is attached to the surface of the textile by a magnetron sputtering method to form the antibacterial layer, so that the antibacterial purpose is achieved. Meanwhile, the factors such as safety, production process difficulty, cost and the like are considered, and the inventor gropes that the compound material containing Ag, Cu, Ti and Zn elements can have an antibacterial effect and a nitrided stainless steel film layer has an antibacterial effect, wherein for a copper film layer, brass and red copper have antibacterial effects.
In the aspect of antibacterial mechanism, the antibacterial mechanism of silver is a natural bactericide scientifically proved at present, and the antibacterial mechanism of zinc oxide and titanium dioxide is a photocatalytic antibacterial mechanism. Under the irradiation of ultraviolet and visible light, valence band electrons of the nano zinc oxide and the nano titanium dioxide are excited to a conduction band to form freely moving negatively charged electrons and positively charged holes, and the holes react with oxygen, hydroxyl and water adsorbed on the surface to generate hydroxyl, oxygen ions and hydrogen peroxide. The active oxygen ions have strong oxidation effect, can react with hydroxyl in various microorganisms to destroy the multiplication capacity of bacterial cells, and achieve the result of bacteriostasis and even sterilization. Zinc oxide slowly releases zinc ions in an aqueous or humid environment. The zinc ion has affinity with bacteria, and when it is combined with bacterial cell membrane, it reacts with organic matter in the cell membrane to break the structure of membrane protein and make it lose activity so as to attain the goal of resisting bacteria.
The antibacterial solution containing nano silver or copper used in the prior art mostly adopts a solution soaking mode, so that the fabric has an antibacterial effect, and the silver and copper are excessively used, so that potential safety hazards are caused. The antibacterial film layer applied by the vacuum deposition method is strictly controllable in dosage and safer, and meanwhile, in order to further reduce the dosage of copper and silver, the antibacterial film layer also adopts copper or silver alloy as the antibacterial film layer, so that the biological safety problem is avoided as much as possible.
The antibacterial film layer has good bonding fastness with the fiber material, is firmer than a chemical reagent soaking or spraying method, is insoluble in water and is not easy to fall off, so that the antibacterial film layer is not required to be washed and is durable for a long time.
In the production process, working gas is required to be continuously introduced for film deposition, nitrogen or oxygen is introduced as the working gas according to the requirements of the film in addition to the necessary argon, for example, the oxygen element of the color generation film and the nitrogen element of the buffer layer and the protective layer are realized by introducing the working gas.
Further, the antibacterial film layer comprises TiNOxFilm layer, TiO2At least one of a film layer, a ZnO film layer, a nitrided stainless steel film layer, an AZO film layer, a copper film layer, a silver-titanium alloy film layer, a copper-zinc alloy film layer or a titanium-aluminum alloy film layer.
Based on the factors of antibacterial mechanism, antibacterial effect, safety, process difficulty and the like, the inventor selects TiNOxFilm layer, TiO2Film layer, ZnO film layer, nitrided stainless steel film layer, AZO film layer,At least one of the copper film layer, the silver-titanium alloy film layer, the copper-zinc alloy film layer or the titanium-aluminum alloy film layer is used as the antibacterial layer. The inventor adopts Ti and compounds thereof, silver and copper alloy, stainless steel and the like as the antibacterial layer, can avoid the biological safety problem caused by excessive nano silver or copper, and has lower production cost.
Further, when the composite film layer comprises the color generation layer and the antibacterial layer, the thickness of the antibacterial layer is 3-400 nm.
Further, when the color of the fabric is derived from the antibacterial layer, the thickness of the antibacterial layer is 3-800 nm.
The film layer on the surface of the colored fabric is applied on the surface of the fabric by means of vacuum deposition, so that the fabric can present various colors, and the specific method can refer to the methods described in patent applications 201810654518.5, 201910601301.2, 201910594850.1 and the like.
The color of the antibacterial fabric is related to the antibacterial layer and/or the color-producing layer. For example, sometimes the color of the antimicrobial shell fabric is related only to the color-producing layer, the color of the shell fabric being derived from the color-producing layer; sometimes, the color of the antibacterial fabric is the result of the combined action of the chromatographic layer and the antibacterial layer; sometimes, the color-generating layer and the antibacterial layer on the surface of the antibacterial fabric are the same film layer, and the color of the colored antibacterial fabric is derived from the antibacterial layer.
The method of adopting the vacuum deposition film layer utilizes the comprehensive effects of absorption, reflection, refraction and the like of the nanometer film layers with different materials and different thicknesses on light, so that the obtained colored fabric presents different colors, and the thickness of the antibacterial layer can also influence the color of the fabric to a certain extent. Therefore, in order to reduce the influence of the antibacterial layer on the color of the fabric, the thickness of the film layer of the antibacterial layer needs to be controlled, and when the thickness of the antibacterial layer exceeds a certain limit, for example, exceeds 400nm, the color of the original raw color layer can be changed, so that the antibacterial effect and the color of the fabric need to be comprehensively considered, and the thickness of the antibacterial layer needs to be controlled, and the applicant finds that the thickness of the antibacterial layer is between 3 and 400nm, so that the antibacterial effect can be ensured, and the color deviation of the fabric can not occur.
In addition to being used as an antimicrobial layer, some of the film layers can also be used as a color-forming layer, or as a raw materialPart of the color layer, together with other color-generating film layers, gives the textile a rich color, that is to say, the textile is colored while achieving an antibacterial effect. Such as TiNOxFilm layer, TiO2The film layer, the AZO film layer and the copper film layer can be used as a color generation layer and an antibacterial layer at the same time. In order to meet the color generation requirement and realize the antibacterial effect, the color generation layer is thicker, and the thickness of the antibacterial layer is 3-800 nm.
Further, the composite film layer further comprises a buffer layer, and the buffer layer is arranged between the surface of the fabric and the antibacterial layer.
Sometimes, in order to improve the bonding fastness between the antibacterial film layer or the color-producing layer and the fabric, a buffer layer needs to be arranged. The buffer layer needs to have good oxidation resistance and corrosion resistance, has a buffering effect, reduces damage to the surface of the fabric when the reflecting layer is sputtered, and can be used as a protective layer of the reflecting layer to prevent oxygen and moisture from entering the reflecting layer from the side, which is not coated, of the fiber fabric to corrode and oxidize the reflecting layer. Meanwhile, the buffer layer also has good adhesive force with the fiber fabric and the reflecting layer, so that the subsequent film layer is well attached to the surface of the fiber fabric. For the above reasons, the buffer layer selected by the applicant comprises a TiAlN film layer and TiNOxAt least one of a film layer, a NiCr film layer, a TiN film layer, a Ti film layer, a stainless steel film layer or a nitrogen-oxygen stainless steel film layer, and for the special antibacterial layer, the film thickness of the buffer layer needs to be controlled within the range of 10-500nm so as to meet the binding force requirements between the film layers and between the buffer layer and the fabric fibers.
Further, when the composite film layer is deposited, the production speed is 0.1-50m/min, the corresponding total power is 0.1-500kW, the gas flow is 10-1000Sccm, and the working pressure is 0.05-2.5 Pa.
In order to enable the fiber fabric to present a preset color and a good antibacterial effect, the thickness of the composite film layer needs to be controlled, and in order to ensure the thickness of the composite film layer, the process of depositing the film layer needs to be controlled, including the vehicle speed, the production power, the gas flow and the working gas pressure, and the color and the antibacterial effect of the fiber fabric which reach the standard can be obtained only when the parameters are controlled within a reasonable range.
The invention also provides a colored antibacterial fabric which is manufactured by the method.
