Embodiment 1

[0038] Dissolve 0.28 g of dopamine hydrochloride powder in 50 mL of deionized water, then add 0.034 g of anhydrous copper chloride to adjust the pH to 8.5. Add 0.1g of 30% hydrogen peroxide and 0.56g of silane coupling agent KH550 into the dopamine solution, stir well and set aside. Draw 3mL of the solution prepared above, and add it to a plastic petri dish covered with silk power textiles with a diameter of about 5cm, so that the liquid completely covers the surface of the fabric. Cover the plastic petri dishes and place them in a constant temperature vacuum oven (at a temperature of 30° C.) to react for different times (1 h, 1.5 h, 2 h, 3 h), and use a syringe to suck off the unreacted liquid. The treated sample is placed in a constant temperature vacuum oven (at a temperature of 30° C.), and after drying, the structural color can be obtained on the surface of the fabric.

Embodiment 2

[0041]0.2 g of gallic acid powder was added to 40 mL of deionized water, and 10 mL of ethanol was added to aid dissolution, and then 0.034 g of anhydrous copper chloride was added to adjust its pH value to 8.5. Add 0.1g of 30% hydrogen peroxide and 0.2g of silane coupling agent KH550 into the gallic acid solution, stir well and set aside. Draw 3mL of the solution prepared above, and add it to a plastic Petri dish covered with wool fabric with a diameter of about 5cm, so that the liquid completely covers the surface of the fabric. Cover the plastic petri dish and place it in a constant temperature vacuum oven (at a temperature of 25° C.) to react for different time respectively, and use a syringe to suck off the unreacted liquid. The treated sample is placed in a constant temperature vacuum oven (temperature is 25° C.), and after drying, the structural color can be obtained on the surface of the fabric. Among them, when reacting for 1h, 2h, 3h and 4h, the structural colors of ...

Embodiment 3

[0043] Add 0.3g of ferulic acid powder into 40mL of deionized water, and add 10mL of ethanol to aid dissolution, then add 0.08g of ferric chloride hexahydrate to adjust its pH value to 8.2. Add 0.08g of ferric chloride hexahydrate, 0.1g of 30% hydrogen peroxide and 0.2g of silane coupling agent KH550 into the ferulic acid solution, stir well and set aside. Draw 3mL of the solution prepared above, and add it to a plastic Petri dish covered with cotton fabric with a diameter of about 5cm, so that the liquid completely covers the surface of the fabric. Cover the plastic petri dish and place it in a constant temperature vacuum oven (at a temperature of 40° C.) to react for different time respectively, and use a syringe to suck off the unreacted liquid. The treated sample is placed in a constant temperature vacuum oven (at a temperature of 40° C.), and after drying, the structural color can be obtained on the surface of the fabric. Among them, when reacting for 1h, 2h, 3h and 4h, ...

Abstract

The invention provides a method for preparing a non-irisation structure color on the surface of a fabric. The method includes the following steps that a polyphenol compound, variable-valency metal ions, an oxidizing agent and a silane coupling agent are dissolved in water, the mixture is mixed evenly, and then a polyphenol solution is obtained; then the fabric is soaked into the solution, reacts for a period in the certain temperature and aerobic environment, residual liquid is removed, the obtained fabric is put into a vacuum oven and dried, and the fabric with the structure color can be obtained. The invention discloses the fabric obtained with the preparing method with different structure colors. The preparing method is simple, required time is short, an environmental-protection effectis achieved, any dye is used in the prepared structure color, the color is even, and the method has broad application prospects.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a non-iridescent structured colored fabric and a preparation method thereof. Background technique [0002] Since the development of human civilization, the demand for beauty has been increasing day by day. In textiles, it has developed from animal fur and leaves to contemporary fashion with various styles and bright colors. The generation of color includes pigment coloring and structural coloring, in which pigment coloring is derived from the selective absorption of various dyes and pigments to specific wavelengths of light and reflects light of other wavelengths; while structural coloring is the use of special physical structures to pass light The selective reflection of the produces color. The mechanism of structural color generation includes thin film interference, diffraction effect of periodic structure, and selective scattering. Among them, thin-film interference includes single-l...
