Description

Technical Field

[0001] The present invention relates to the field of trademark tapes, and in particular to an eco-friendly trademark cloth suitable for water-based ink printing and its printing device. Background Art

[0002] A trademark tape is a textile label that identifies information such as the brand, size, price, composition, and care of various textiles. It is one of the most widely used product identifiers in current products such as clothing, shoes and hats, luggage, and home textiles, and is closely related to our lives. The current printing methods of trademark fabrics are mainly flexographic printing, rotary printing, and offset printing, etc., which are difficult to achieve the characteristics of small batches, multiple varieties, and quick response. With the development of inkjet printing technology, inkjet printers have become the mainstream printing equipment in the current graphic output field. They are small in size, simple and flexible to operate. The ink used in inkjet printing is mainly water-based ink, and water-based ink has significant environmental protection and safety characteristics such as being safe, non-toxic and harmless, non-flammable and non-explosive, and almost no volatile organic gases are generated. However, when water-based ink is printed on existing trademark fabrics, irregular diffusion will occur, the clarity of the printed image is difficult to guarantee, and the color fastness of the printed information is not high, seriously affecting the basic functions and recognition effects of the trademark cloth. Therefore, it is necessary to propose an eco-friendly trademark cloth suitable for water-based ink printing and its printing device. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the background art and provide an eco-friendly trademark cloth suitable for water-based ink printing and its printing device.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: An eco-friendly trademark cloth suitable for water-based ink printing includes a nylon-polyester plain weave base cloth. The D number of the nylon-polyester plain weave base cloth is 40D - 80D, and the F number is 1F - 48F. A coating is provided on the nylon-polyester plain weave base cloth. The coating uses nylon waste silk coating glue, and the formula of the nylon waste silk coating glue is: 90 - 110 g of methanol, 30 - 40 g of calcium chloride; 31 - 41 g of citric acid-modified kaolin; 0.1 - 0.4 g of dispersant CF-10.

[0005] When the vertical penetration speed of the ink on the coating surface is equal to the horizontal diffusion, it is the most ideal state. In this state, quick drying of the ink marks can be achieved, with high color density, clear lines, and high font resolution. Therefore, it is necessary to effectively regulate the surface properties and structure of the trademark cloth. In the present invention, by selecting a filler with a large specific surface area, small particle size and uniform distribution, an appropriate ratio of glue to pigment, and controlling a suitable coating thickness, a microporous structure with uniform pore size and high porosity is formed in the coating film, and increasing the total pore volume of the coating can effectively improve the ink absorption of the coating, make the ink solidify faster, and achieve the effect of quick drying, solving the problem that the existing trademark tape shows irregular diffusion on an inkjet printer, resulting in unclear printing.

[0006] The present invention selects a nylon-polyester plain fabric as the coating base cloth, with a D number of 40D - 80D and an F number of 1F - 48F, which is resistant to friction, has high tensile strength, and good tear resistance. Moreover, the texture of the base cloth is open and the structure is loose, making it easy for the coating agent to penetrate, with strong adhesion and the coating agent not easily falling off, and it can be applied to inkjet printing. At the same time, nylon waste filaments are dissolved in a methanol solution of calcium chloride, and a certain proportion of fillers are added to make a coating adhesive for coating the base cloth. The produced coated cloth has good hand feeling, printing performance, etc., expanding the new uses of nylon waste filaments.

[0007] An emulsion prepared by fully dissolving industrial nylon waste filaments in a methanol-calcium chloride solution system, and then adding a certain amount of citric acid-modified kaolin and a dispersant CF-10, with a weight part composition ratio of 40 - 60 parts of methanol, 20 - 30 parts of calcium chloride, 10 - 20 parts of nylon 6 waste filaments, 10 - 20 parts of fillers, and 0.06 - 0.1 part of a whitening agent, can be used to make a coating adhesive for coating the trademark cloth. In addition, methanol solution is used, which can be recycled and reused in the subsequent solvent recovery process. Under the test conditions of fixing the amount of modified kaolin at 60 g and the amount of dispersant CF-10 at 0.3 wt%, by studying the influence of the amount of nylon waste filament coating agent on the coating adhesion, a more suitable amount of coating agent is determined.

[0008] A preparation method for an eco-friendly trademark cloth applicable to water-based ink printing includes the following steps: S1, Desizing and washing, alkali-washing and rinsing the nylon-polyester plain base cloth with water; S2, Drying and shaping, drying and shaping the nylon-polyester plain base cloth after desizing and washing, with a shaping temperature of 150 - 180 °C and a vehicle speed of 50 - 70 m / min; S3, Preparation of Nylon Waste Silk Coating Adhesive: Weigh the optical brightener and slowly add it to methanol with stirring for dissolution. After heating to 60 - 65 °C, add calcium chloride and stir for reaction for 30 - 45 min. Then weigh and cut the nylon waste silk into pieces and add it to the above mixture. Wait until the waste silk is completely dissolved into a clear liquid, continue stirring for 1 h, then add modified kaolin. After stirring for 30 min, lower the temperature to 50 °C and add polyether, stir for 15 min and set aside, with the viscosity controlled at 500 - 1000 CP; S4, Coating and Roller Pressing: Coat the prepared nylon waste silk coating adhesive on the nylon - polyester plain weave base fabric, and then perform roller pressing; S5, Drying: After coating and roller pressing, perform drying to obtain an eco - friendly trademark fabric suitable for water - based ink printing.

[0009] Through the selection of nylon - polyester plain weave base fabric, nylon waste silk coating adhesive, and the design of processes such as desizing, washing, drying and shaping, preparation of nylon waste silk coating adhesive, coating and roller pressing, and drying, the trademark tape products in this case have the characteristics of high friction resistance, high tensile strength, and good tear resistance, and at the same time are applicable to the printing of water - based ink, solving the problems of irregular diffusion of water - based ink printing on existing trademark tapes, difficulty in ensuring the clarity of printed images, and low color fastness.

[0010] An eco - friendly trademark fabric printing device includes a frame. From right to left, the frame is successively provided with a tape feeding mechanism for facilitating the printing of eco - friendly trademark fabric, a cleaning mechanism, a printer placement rack, a tape discharging mechanism, a tension control mechanism, and a winding roller. An inkjet printer is provided in the printer placement rack, adopting a water - based ink spraying process. Its ink has no pungent smell, and the trademark tape has no smell or toxicity after spraying, making an important contribution to the ecological safety in the production process of coated textiles, and conforming to the theme of green ecology and low - carbon environmental protection in this era.

[0011] In this invention, the trademark tape is conveyed to the printer placement rack by the tape feeding mechanism in this case and printed by the inkjet printer, and then wound by the tape discharging mechanism, so that the trademark tape can be synchronized with the paper feeding of the printer during printing, with clear printing and no double - image. It is applicable to trademark tape printers for water - based ink printing, with a small volume, simple and flexible operation, making up for the defect that the current trademark fabric printing method is difficult to achieve small - batch, multi - variety, and quick - response production. At the same time, the tension control mechanism ensures the tightness of winding, thus facilitating winding.

[0012] Preferably, the tension control mechanism includes a first rotating motor, a fixed shaft, a swing rod, and a cross bar. The first rotating motor is fixed on the frame, the fixed shaft is fixed at the output end of the first rotating motor, two swing rods are sleeved and fixed on the outer side wall of the fixed shaft, the cross bar is fixed between the two swing rods, and the winding roller is controlled by a second rotating motor. The motor end of the second rotating motor is fixed on the frame. The first rotating motor and the second rotating motor can be servo motors.

[0013] In the present invention, the trademark tape passes through the bottom of the cross bar. The first rotating motor continuously outputs downward with a set fixed torque. When the upward force is greater than the set torque, the motor will be pulled upward by the directional force, thereby generating an angle to compensate the speed of the winding shaft, achieving the balance of the whole machine's linear speed, thereby tensioning the trademark tape, making the trademark tape closely adhere to the winding, and thus facilitating winding.

[0014] There are two or more cross bars arranged in parallel, which enables the trademark tape to be adjusted according to requirements.

[0015] Preferably, the tape output mechanism includes an output limiting roller, an output guiding roller, and a downwardly inclined arc-shaped inclined transition plate. One side of the printer placement rack is provided with a fabric inlet, and the other side is provided with a fabric outlet. The output limiting roller is arranged at the fabric outlet, the arc-shaped inclined transition plate is arranged behind the output limiting roller, the output guiding roller is arranged between the tension control mechanism and the arc-shaped inclined transition plate, and the winding roller is arranged at the upper right of the tension control mechanism.

[0016] The tape input mechanism includes a fabric output roller fixed on the frame, a first fabric input guiding roller, a first fabric input limiting roller, a second fabric input guiding roller, and a second fabric input limiting roller. The second fabric input limiting roller is arranged at the fabric inlet, the second fabric input guiding roller is arranged below the second fabric input limiting roller, the first fabric input limiting roller is arranged below the second guiding roller, the first fabric input guiding roller is arranged below the printer placement rack, and the fabric output roller is arranged at the lower right of the first fabric input guiding roller.

[0017] In the present invention, the trademark tape of this case passes through the first fabric input guiding roller, the first fabric input limiting roller, the second fabric input guiding roller, and the second fabric input limiting roller in sequence and then enters the printer, which can ensure the paper feeding speed. The output limiting roller limits the trademark tape coming out of the printer. Then the trademark tape is guided downward through the arc-shaped inclined transition plate to the output guiding roller, then passes through the tension control mechanism, and then is wound by the winding roller. In this way, the winding speed and the paper output speed of the printer can be synchronized, ensuring synchronous paper feeding, making the printing clear and without double images.

[0018] Preferably, the first feeding limiting roller, the second feeding limiting roller and the discharging limiting roller each include a roller body, two limiting rings are sleeved on the roller body, more than three limiting holes are formed in the limiting rings, and a tightening rod is threadedly connected in the limiting holes.

[0019] In the present invention, the printing width is limited by the two limiting rings on the first feeding limiting roller, the second feeding limiting roller and the discharging guiding roller, so that the printer can adjust the printing width according to different production requirements. The limiting rings are fixed by screwing the tightening rods into the limiting holes, which is more convenient.

[0020] Preferably, the cleaning mechanism includes an upper cleaning plate with a hollow interior, a lower cleaning plate with a hollow interior, a connecting plate with a hollow interior, a collecting box with a hollow interior, and a suction fan. The connecting plate is fixed on the frame, the upper cleaning plate is fixed above the connecting plate, the lower cleaning plate is fixed below the connecting plate, the upper cleaning plate, the lower cleaning plate and the connecting plate communicate with each other. Dust inlet openings are formed on the opposite surfaces of the upper cleaning plate and the lower cleaning plate, and brush strips are arranged around the dust inlet openings. An air outlet is formed on the back of the connecting plate. An inlet is arranged on the left side of the collecting box, and an outlet is arranged on the right side of the collecting box. The air outlet is connected to the inlet, and the suction fan is connected to the outlet.

[0021] In the present invention, through the brush strips of the upper cleaning plate and the lower cleaning plate, when the trademark tape passes through the cleaning mechanism, the dust on the surface of the trademark tape is cleaned by the brush, and then the dust is sucked into the collecting box through the dust inlet for collection, preventing the dust from adhering to the surface of the trademark tape, resulting in problems such as defects and blurring of the trademark tape, which affect the color accuracy and clarity of the trademark tape.

[0022] The collecting box includes a hollow filter box body, a primary filter screen, a secondary filter screen, and a half door. The filter box body is divided into a primary filtering area and a secondary filtering area from left to right. Four primary filter screens are connected in a toothed shape from top to bottom in the primary filtering area in sequence, and four secondary filter screens are connected in a toothed shape from top to bottom in the secondary filtering area in sequence. U-shaped grooves for detachably connecting the primary filter screen and the secondary filter screen are arranged in the filter box body. The four half doors are all arranged on the front of the filter box body through hinges, and each half door corresponds to a filter screen. The tips of the toothed shapes formed by the primary filter screen and the secondary filter screen all face the inlet. The secondary filter screen, the inlet and the outlet of the filter box body gradually decrease in diameter from the side close to the filter box body to the side far from the filter box body.

[0023] When the dust of the present invention enters the collecting box, it first enters the primary filtering area and is blocked by the primary filter screen to block large particles, and then passes through the secondary filtering area to block small particles, realizing dust collection while extending the service life of the filter screen.

[0024] The filter screen of the present invention is distributed in a toothed shape, which reduces the occupied area while increasing the area of the filter screen, thereby enhancing the filtering effect. At the same time, each filter screen is detachably connected to the filter box through a U-shaped groove, enabling partial replacement, reducing costs, and being more environmentally friendly.

[0025] The half door provided in the present invention facilitates the replacement of the filter screen. In summary, the beneficial effects of the present invention are as follows: 1. By selecting a filler with a large specific surface area, small particle size, and uniform distribution, an appropriate glue-to-pigment ratio, and controlling a suitable coating thickness, the present invention enables the coating film to form a microporous structure with uniform pore size and high porosity, increasing the total pore volume of the coating and effectively improving the ink absorption of the coating, causing the ink to solidify faster and achieving a quick-drying effect, thereby solving the problem that the existing trademark tape shows irregular diffusion on an inkjet printer, resulting in unclear printing. 2. The present invention selects a nylon-polyester plain fabric as the coating base fabric, with a D number of 40D - 80D and an F number of 1F - 48F. It is resistant to friction, has high tensile strength, and good tear resistance. Moreover, the structure of the base fabric is open and loose, facilitating the penetration of the coating agent, having strong adhesion, and the coating agent is not easily detached. It is suitable for inkjet printing. At the same time, nylon waste filaments are dissolved in a methanol solution of calcium chloride, and a certain proportion of fillers are added to make a coating glue for coating the base fabric. The produced coated fabric has good hand feeling, printing performance, etc., expanding the new uses of nylon waste filaments. 3. By passing the trademark tape of the present case through the first fabric-feeding guide roller, the first fabric-feeding limiting roller, the second fabric-feeding guide roller, and the second fabric-feeding limiting roller in sequence and then entering the printer, the paper-feeding speed can be ensured. The trademark tape is limited by the discharging limiting roller after coming out of the printer. Then, the trademark tape is guided downward to the discharging guide roller through the arc-shaped inclined transition plate, and then passes through the tension control mechanism, and finally is wound by the winding roller. In this way, the winding speed and the paper-feeding speed of the printer can be synchronized, ensuring synchronous paper feeding, resulting in clear printing without double images. 4. Through the brush strips of the upper cleaning plate and the lower cleaning plate in the present invention, when the trademark tape passes through the cleaning mechanism, the dust on the surface of the trademark tape is cleaned by the brushes. Then, the dust is sucked into the collection box through the dust inlet for collection, preventing the dust from adhering to the surface of the trademark tape, which may cause problems such as defects and blurring of the trademark tape, affecting the color accuracy and clarity of the trademark tape. 5. When the dust enters the collection box in the present invention, it first enters the primary filtration area and is blocked by the primary filter screen to block large particles, and then passes through the secondary filtration area to block small particles. While realizing dust collection, the service life of the filter screen is extended. At the same time, the filter screen is distributed in a toothed shape, reducing the occupied area while increasing the area of the filter screen, thereby enhancing the filtering effect.

[0027] The following specific embodiments are only explanations of the present invention and are not limitations thereof. Those skilled in the art can make modifications without creative contributions to these embodiments after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the Patent Law.

[0028] The present invention will be described in detail below with reference to the accompanying drawings by way of examples.

[0029] Example 1

[0030] As Figure 1 and 15As shown in the figure, an eco-friendly trademark cloth suitable for water-based ink printing is characterized by including a nylon-polyester plain weave base cloth. The D count of the nylon-polyester plain weave base cloth is 40D - 80D, and the F count is 1F - 48F. A coating is provided on the nylon-polyester plain weave base cloth, and the coating uses nylon waste silk coating glue.

[0031] The formula of the nylon waste silk coating glue is as follows: 100g of methanol, 35g of calcium chloride; 31 - 41g of citric acid-modified kaolin; 0.3g of dispersant CF-10; 0 - 2.5g of polyether; 0.3g of whitening agent.

[0032] As Figure 2 shown, the preparation method of the eco-friendly trademark cloth suitable for water-based ink printing includes the following steps: S1, Desizing and washing, alkali-washing and then cleaning the nylon-polyester plain weave base cloth with clear water. S2, Drying and shaping, drying and shaping the nylon-polyester plain weave base cloth after desizing and washing. The shaping temperature is 150 - 180°C, and the vehicle speed is 50 - 70m / min. S3, Preparation of nylon waste silk coating glue, weighing the whitening agent, slowly adding it to methanol and stirring to dissolve. After heating to 60 - 65°C, add calcium chloride, stir and react for 30 - 45min. Then weigh and cut the nylon waste silk into pieces and add them to the above mixture. Wait until the waste silk is completely dissolved into a clear liquid, continue stirring for 1h, then add modified kaolin, stir for 30min, then lower the temperature to 50°C and add polyether, stir for 15min and set aside. The viscosity is controlled at 500 - 1000CP. S4, Coating and roll pressing, applying the prepared nylon waste silk coating glue on the nylon-polyester plain weave base cloth, and then performing roll pressing. S5, Drying, drying after coating and roll pressing to obtain the eco-friendly trademark cloth 100 suitable for water-based ink printing.

[0033] The adhesion between the sizing film and the substrate surface was measured by the cross-cut method to explore the influence of the dosage of nylon waste silk coating agent on the coating bonding strength. When the dosage of the coating agent is lower than 12.0wt%, the bonding strength between the sizing film and the substrate is poor, and the sizing film is easy to peel off from the substrate surface. Therefore, it is more appropriate to set the dosage of the nylon waste silk coating agent to 12.0wt%.

[0034] The stiffness of the coating material increases with the increase of the drying temperature. This may be because the increase of the drying temperature enhances the bonding effect of the coating agent, making the sizing film have a certain elasticity, thus increasing the stiffness. However, when the drying temperature exceeds 150 °C, the folding endurance of the coating material will decrease, and blisters will appear on the surface. This may be because after the second top coating, some pores on the coating surface will be covered and filled, resulting in a decrease in the porosity. Part of the water vapor is difficult to evaporate, so bubbles are formed on the surface, leading to a decrease in the folding endurance of the coating material. Therefore, it is more appropriate to set the drying process to a drying temperature of 150 °C and a drying time of 3 minutes. Under this test condition, the coating material obtained has good folding endurance and a relatively soft handfeel.

[0035] To achieve a clear trademark pattern, the printer is equipped with a high-resolution print head and adopts advanced inkjet technology to achieve precise ink droplet control and positioning, ensuring that fine lines and texts can be printed on the coated trademark tape. The printer is equipped with a rapid drying system, such as hot air drying, to ensure that the printed trademark tape can be quickly dried, reducing adhesion and smudging. The printer can output directly from computer plate making, enabling easy small-batch production, suitable for personalized and customized products. It allows for quick design changes, making it very suitable for short-run and customized printing requirements. The design is applicable to a trademark tape printer for water-based ink printing: the device has excellent characteristics such as small size, simple and flexible operation, high-quality printing effect, rapid curing, flexibility, and customization.

[0036] As Figures 16 - 17 shown, the same trademark tape is printed through an inkjet printer and the printing device of this case respectively. As shown in the figure, the trademark tape printed by an ordinary inkjet printer is not clear and has black ink stains, while the trademark tape printed by the printing device of this case is clearly printed without ink stains.

[0038] As Figure 6 shown, the first cloth feeding limiting roller 23, the second cloth feeding limiting roller 25, and the discharging limiting roller 52 each include a roller body 231. Two limiting rings 232 are sleeved on the roller body 231. Three or more limiting holes 233 are opened on the limiting rings 232. A tightening rod 234 is threadedly connected in the limiting holes 233.

[0039] As Figures 5 - 14As shown, the cleaning mechanism 8 includes an upper cleaning plate 81 with a hollow interior, a lower cleaning plate 82 with a hollow interior, a connecting plate 83 with a hollow interior, a collection box 84 with a hollow interior, and a suction fan 85. The connecting plate 83 is fixed on the frame 1. The upper cleaning plate 81 is fixed above the connecting plate 83. The lower cleaning plate 82 is fixed below the connecting plate 83. The upper cleaning plate 81, the lower cleaning plate 82, and the connecting plate 83 are interconnected. Dust inlet openings 820 are formed on the opposite faces of the upper cleaning plate 81 and the lower cleaning plate 82. Brush strips 821 are provided around the dust inlet openings 820. A dust outlet 831 is formed on the back of the connecting plate 83. An inlet is provided on the left side of the collection box 84, and an outlet is provided on the right side of the collection box. The dust outlet 831 is connected to the inlet. The suction fan 85 is connected to the outlet.

[0040] As Figures 10 - 13 As shown, the collection box 84 includes a hollow filter box body 841, a primary filter screen 842, a secondary filter screen 843, and half doors 844. The filter box body 841 is divided into a primary filtration area 845 and a secondary filtration area 846 from left to right. Four primary filter screens 845 are connected in a toothed shape and arranged vertically from top to bottom in the primary filtration area 845.

U-shaped grooves 847 are provided in the filter box body for the detachable connection of the primary filter screen 845 and the secondary filter screen 846. The four half doors 844 are all arranged on the front of the filter box body 841 through hinges. Each half door corresponds to a filter screen. The tips of the toothed shapes formed by the primary filter screen 845 and the secondary filter screen all face the inlet. For the secondary filter screen, the inlet and outlet of the filter box body gradually decrease in diameter from the side close to the filter box body to the side far from the filter box body.

[0041] Working principle: As Figures 1 - 15As shown in the figure, when the present invention is in use, loosen the jacking rod, adjust to the required width through the limiting ring 232, and then start printing. The trademark tape in this case first passes through the first guiding roller 22, and then passes through the cleaning mechanism 8. The brush strip 821 on the cleaning mechanism 8 sweeps the dust on the surface of the trademark tape. Then the dust is sucked into the collection box 84 through the dust inlet 820 for collection, preventing the dust from adhering to the surface of the trademark tape, resulting in problems such as defects and blurriness on the trademark tape, affecting the color accuracy and clarity of the trademark tape. Then the cleaned trademark tape enters the inkjet printer 3 through the first feeding limiting roller 23, the second feeding guiding roller 24, and the second feeding limiting roller 25. After printing, the trademark tape passes through the discharging limiting roller 51, and then the trademark tape is guided downward to the discharging guiding roller 52 through the arc-shaped inclined transition plate 53. Then the trademark tape passes through the bottom of the cross bar 64. The first rotating motor 61 continuously outputs downward, setting a fixed torque. When the upward force is greater than the set torque, the motor will be pulled upward by the directional force, thereby generating an angle to compensate the speed of the take-up reel, achieving the balance of the whole machine's linear speed, thereby tensioning the soft trademark tape, making the trademark tape tightly adhere to the take-up. Through such a design, the trademark tape can be synchronized with the paper feeding of the printer during printing, with clear printing and no double images. It is applicable to trademark tape printers for water-based ink printing, with a small volume, simple and flexible operation, making up for the defects that the current trademark fabric printing method is difficult to achieve small batches, multiple varieties, and quick response. At the same time, the tension control mechanism ensures the tightness of winding, thus facilitating take-up.

[0042] During the whole process, when the dust enters the collection box 84, it first enters the primary filtration area 845 and is blocked by the primary filter screen 842 to block large particles, and then passes through the secondary filtration area 846 to block small particles, realizing dust collection while prolonging the service life of the filter screen.

[0044] Different from Embodiment 1, the formula of the nylon waste silk coating glue is: 90 g of methanol, 30 g of calcium chloride; 31 g of citric acid-modified kaolin; 0.1 g of dispersant CF-10; 0 - 2.5 g of polyether; 0.3 g of whitening agent.

[0045] Embodiment 3

[0046] Different from Embodiment 1, the formula of the nylon waste silk coating glue is: 110 g of methanol, 40 g of calcium chloride; 41 g of citric acid-modified kaolin; 0.4 g of dispersant CF-10; 0 - 2.5 g of polyether; 0.3 g of whitening agent.

[0047] Taking the mass ratio of nylon waste silk coating agent to modified kaolin as a variable, the influence of the ratio of coating agent to modified kaolin on the ink absorption and covering power of the coating material was explored. When the ratio of coating agent to modified kaolin was 1:3, the void distribution on the surface of the coating material was relatively uniform, and the pore size was relatively consistent, which was conducive to the longitudinal absorption of ink. At this time, the surface contact was the smallest and the ink absorption was better. Finally, the formula of nylon waste silk coating glue was determined as follows: 100 g of methanol; 35 g of calcium chloride; 36 g of citric acid modified kaolin; 0.3 g of dispersant CF-10; 0-2.5 of polyether; 0.3 g of whitening agent.
