Description

Colorful fiber fabric

Technical Field

The utility model relates to a fiber fabric especially relates to a colored fiber fabric is being in vacuum.

Background

The vacuum deposition technology is adopted to deposit the film layer on the surface of the fiber fabric, the novel green and healthy fiber fabric coloring technology is adopted, the basic performance of the fiber fabric is not influenced, meanwhile, the purpose of coloring the fiber fabric can be achieved by utilizing the interaction generated between light and a film, such as reflection, refraction, scattering, diffraction, interference and the like, no waste gas and waste water are discharged in the whole production process, and the metal elements contained in the film layer on the surface of the fiber fabric are safe and harmless to a human body.

The applicant attempts to achieve the colouring of the fibre fabric by depositing a single film layer, i.e. a single layer of dielectric film or metal film deposited on the surface of the fibre fabric, or a double film layer, i.e. a composite film layer of metal film and dielectric film deposited on the surface of the fibre fabric. The single film layer and the double film layers have the advantages of simple preparation and easy color control. However, in the practical process of the applicant, the durability and serviceability of the two film structures are relatively poor, because most metals with active chemical properties, especially metals such as Ag, Cu, etc., are oxidized and corroded after being exposed in the air for a period of time, so that the color changes or the fastness of the film layer is reduced, the color difference or the color fastness cannot reach the standard, and the service life of the fiber fabric is further influenced. The applicant also finds that the color of the metal film layer beyond a certain thickness, namely the color of the metal material, does not change along with the change of the thickness, and the color is single; most dielectric film layers and film layers with different thicknesses show little color change, few color types, low color saturation and no vivid color, and cannot meet the requirements of consumers on fashion.

Therefore, a new film structure is needed to be developed to overcome the defects of insufficient color richness, poor oxidation resistance and wear resistance of the film, color fastness not meeting the national standard and the like of the fiber fabric in the prior art, and the requirements of practical use and industrial production of the fiber fabric are met.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect among the prior art, the utility model provides a colored fiber surface fabric, its surface is multilayer membrane system structure, reaches the purpose of color regulation and control through the stack of different retes and the change of rete thickness, makes the fibre demonstrate abundant colour, improves the anti-oxidant, the resistance to corrosion of compound rete through increasing buffer layer and protective layer simultaneously, makes the colored rete of fiber surface fabric surface plating more lasting, solves the not up to standard problem of fiber surface fabric colour fastness among the prior art. Colored fiber's simple process, the controllability is strong, is particularly suitable for scale industrial production.

In order to achieve the above object, the utility model provides a colored fiber fabric:

the color fiber fabric is provided with at least one surface deposited composite film layer, and the composite film layer sequentially comprises a buffer layer, a reflecting layer, a first protective layer, a color generation layer and a second protective layer from bottom to top; the color generation layer comprises ZnO and Fe₂O₃、TiO₂And CuO; the color of the colored fibers varies with the thickness of the color-producing layer.

The color generation layer is a main film layer which enables the fiber fabric to present colors, and the purpose of controlling and adjusting the colors can be achieved by adjusting the thickness of the color generation layer film, so that the fiber fabric presents different colors. In the utility model, the color generating layer adopts ZnO and Fe₂O₃、TiO₂And CuO, which have particular optical properties, which, in combination with a highly reflective layer, can produce significant thin film interference effects in the thickness range up to 200nm, exhibiting different colors.

The reflecting layer has the function of selectively absorbing and highly reflecting visible light which penetrates through the color generating layer and reaches the surface of the color generating layer, so that the color presented by the fiber fabric has higher brightness and saturation. The reflecting layer is Ag and/or Cu.

But only the reflective layer and the color-generating layer cannot meet the use requirements. The reason is that: ag and/or Cu metal used for the reflecting layer has active chemical properties and is easy to oxidize and discolor; most of oxide materials selected by the color generating layer can be quickly corroded in a sweat (acid) environment to generate color change; most of the oxide materials selected for the color-forming layer do not have high hardness, and if the color-forming layer is directly exposed, the thickness of the film layer is easily lost or the film is easily peeled off due to external friction, so that color change is generated. Therefore, a dense, chemically stable film must be applied to both sides of the reflective layer and the color-forming layer to protect these two important layers.

According to the utility model relates to a raw color layer for use, comprehensively consider fiber surface fabric's raw color layer characteristic, colour regulation and control, oxidation resistance, corrosion resisting property, the colour fastness is up to standard, fiber surface fabric's serviceability and production efficiency and factor such as cost, the utility model discloses a multilayer composite film layer structure, from the basement of fiber surface fabric from interior toward outer deposit buffer layer in proper order, reflector layer, first protective layer, raw color layer and second protective layer to realize colour regulation and control and solve the problem that metal film layer easily oxidized, reach the purpose of colour regulation and control, solved the anti oxidation corrosion resistance who improves fiber surface fabric surface rete simultaneously, make its surface plating's colored rete durable more lastingly.

In the production process, need continuously let in working gas and carry out the rete deposit, except necessary argon gas, still can let in nitrogen gas or oxygen as working gas according to the demand of rete, for example the utility model discloses the oxygen element of well chromogenic film layer and the nitrogen element of buffer layer and protective layer are just realized through the form of letting in working gas.

Further, the inventor finds that ZnO and Fe are adopted as the color generating layer through a large amount of experiments₂O₃、TiO₂Or CuO, when the thickness of the color-forming layer is controlled within 6-200nm, the color of the fiber fabric can be changed by adjusting the thickness of the film layer of the color-forming layerAnd (4) transforming. With the increase of the thickness of the color generation layer, yellow, red, purple, blue and green appear on the surface of the fiber fabric in sequence, when the thickness of the color generation layer reaches 200nm, the thickness of the film layer is continuously increased, the color of the surface of the fiber fabric is changed from green to yellow, and the next same color cycle is entered. That is, the change of the film layer corresponds to the change of the color, and has the characteristic of periodic change. Because the wear-resistant capability of the composite film layer is reduced due to the excessively thick film layer, and the hand feeling of the fiber fabric is affected, generally, in order to improve the production efficiency, the thickness of the color layer is controlled within 6-200nm, namely, the thickness of the color layer is the thinnest at the moment, and the wear-resistant performance of the fiber is better.

It can be understood from the above that if the composite film layer is deposited on both surfaces of the base material, both surfaces of the fiber fabric have colors, and when the thicknesses of the film layers on both sides are different, the colors of the two surfaces are different, so that the fiber fabric with double colors is obtained. For the double-sided fiber fabric, the composite film layers are deposited on two sides, so that the oxidation resistance of the double-sided fiber fabric is more excellent.

In order to ensure that the thickness of the green layer is controlled within 6-200nm, the total production current during deposition of the green layer is generally controlled within 10-80A, which corresponds to a production speed of 1 m/min.

Furthermore, when the buffer layer is selected, the buffer layer needs to have good oxidation resistance and corrosion resistance, has a buffer effect, reduces damage to the surface of the fabric when the reflecting layer is sputtered, and can also 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. Based on the above reason and the selection of the color generation layer and the reflection layer, the utility model discloses select at least one in Ti, TiN and the nitriding stainless steel as the buffer layer.

Further, in order to not affect the color of the fiber fabric, the thickness of the film layer of the buffer layer needs to be controlled, and the inventor finds through a great deal of practice that when the thickness of the buffer layer is 10-100nm, the buffer layer has good oxidation resistance and corrosion resistance, and simultaneously has better bonding force with the fiber fabric and the reflecting layer. To ensure that the thickness of the buffer layer is controlled within 10-100nm, the total production current during the deposition of the buffer layer is generally controlled within 10-120A, which corresponds to a production speed of 1 m/min.

Further, ZnO and Fe are used₂O₃、TiO₂Or CuO is used as the raw color layer, the reflecting layer is Ag and/or Cu, and the two materials have good bonding force with the raw color layer and are safe and harmless to human bodies.

Further, in order to realize the functions of selective absorption and high reflection of visible light by the reflective layer without affecting the color exhibited by the color-producing layer, it is necessary to control the thickness of the reflective layer to be in the range of 20 to 300 nm. To ensure that the thickness of the reflective layer is controlled within 20-300nm, the total production current during deposition of the reflective layer is typically controlled within 5-50A, which corresponds to a production speed of 1 m/min.

Further, the first protective layer is made of TiN and/or nitrided stainless steel in consideration of the film layer materials, film layer thicknesses, and the like of the color generating layer, the reflective layer, and the buffer layer, according to the function of the first protective layer.

Further, in order to control the thickness of the film layer on the surface of the fiber fabric within a certain range, not only the color, oxidation resistance and color fastness of the film layer are ensured, but also the thickness of the film layer is reduced as much as possible, when the first protective layer is deposited, the total production current is 10-120A, the production speed corresponding to the production current is 1m/min, and the thickness of the first protective layer is controlled within 10-100 nm.

Further, in addition to the buffer layer, the reflective layer, the first protective layer and the color-generating layer, a second protective layer, such as TiO, is added to the composite film layer₂And/or SiO₂And/or retes such as TiN, the second protective layer is the rete of top layer in the compound rete, is used for protecting the chromatographic layer on the one hand, avoids the chromatographic layer to drop in the use, causes fibre surface fabric surface mottled, and then the uneven problem of colour appears, and on the other hand can hinder oxygen and get into the reflection stratum, improves the fine fibre of structural colorThe durability of the fiber fabric. The second protective layer is added on the top layer of the fiber fabric, so that the dual-protection effect can be realized, and the wear resistance of the film layer is further increased.

Further, in order to realize the above protection function, avoid affecting the color of the fiber fabric, and not affect the industrial production efficiency too much, the thickness of the protection layer needs to be controlled within 10-100 nm. To ensure that the thickness of the protective layer is controlled within 10-100nm, the total production current during the deposition of the second protective layer is generally controlled within 10-120A, which corresponds to a production speed of 1 m/min.

Further, in the utility model discloses an in the implementation, the inventor finds, when needing nitrogen gas or oxygen and argon gas mixture as working gas, if nitrogen gas or oxygen proportion is too low, then the nitrogenize or the oxidation of metal is incomplete, and the rete is constituteed inconsistently, leads to the colour inhomogeneous, if nitrogen gas or oxygen proportion is too high, then can cause gaseous extravagant, improves manufacturing cost. Therefore, the flow ratio of the working gas needs to be controlled within a certain range to form an excellent film structure. Through a large number of experiments, the inventor selects to control the working gas ratio in the following range: when the working gas is argon and nitrogen, the flow ratio of the argon to the nitrogen is 1: 0.4-4; and when the working gas is argon and oxygen, the flow ratio of the argon to the oxygen is 1: 0.4-4. It is easy to understand that if the film layer does not contain nitrogen or oxygen, only argon is needed to be introduced as the working gas.

Furthermore, the production speed can be adjusted in the implementation process of the utility model, and the range is 1-20 m/min. It can be understood that the production speed changes, and the time for the fiber fabric to pass through each film layer target material changes, so that the thickness of the film layer changes. In order to ensure the stable thickness of each film layer, the total power of each film layer target material is adjusted in equal proportion while the production speed is adjusted. The method mainly comprises two methods, namely, the number of the target materials is increased or decreased; and secondly, the production current of each target material is increased and decreased.

The working vacuum degree is also an important factor for realizing the production method of the utility model, if the vacuum degree is too high, the gas amount in the coating chamber is too small, which can cause the sputtering working gas to be insufficient, thereby influencing the sputtering rate; if the degree of vacuum is too low, the amount of gas in the coating chamber becomes too large, which may block target atoms or molecules from sputtering onto the fiber surface and also decrease the sputtering rate. Therefore, the practice of the inventor shows that the working vacuum degree needs to be controlled within the range of 8.0E-2-3E-3Pa during the production process so as to achieve the optimal deposition state.

The utility model also provides a colored fiber made through the above-mentioned production method, this colored fiber has abundant color and good colour fastness, and accessible industrial method preparation obtains moreover.
