Fabric coloring method and colored fabric

Abstract

The invention provides a fabric coloring method and a colored fabric. The fabric coloring method includes steps: subjecting base cloth to radiation drying treatment; performing vacuum deposition to sequentially form an adhesive layer and at least one coloring layer on the surface of the base cloth subjected to radiation drying treatment, wherein the adhesive layer comprises at least one of Ti, Cr,Si and Ni and is in thickness of 1-2000nm, each coloring layer comprises at least one of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au and Mg, and the total thickness of the at least one coloring layer is 1-4000nm.By adoption of the coloring method, rich colors can be generated, high color fastness of the colored fabric is realized while film thickness sensitivity of the color of the colored fabric is reduced,and accordingly industrial operability is improved.

Description

technical field [0001] The invention relates to fabric coloring technology, in particular to a fabric coloring method and the colored fabric. Background technique [0002] In the existing color system, it is distinguished according to the principle of color production, and there are mainly two methods of color production: pigment color and structural color. The color of the pigment is mainly determined by the chemical bonds in the substance molecules - the electrons in some chemical bonds are in a state that absorbs specific wavelengths of visible light very easily, while other wavelengths are reflected to show different colors. The substance that can play such an effect is a pigment, and such a color is called a pigment color. Pigment color can be understood as an inherent property of materials. [0003] Structural color, also known as physical color, is due to the special structure of the surface of the object, which causes the light wave to refract, diffuse, diffract or...

At the same time, volatile pollutants will be produced during the preparation and production of dyes

[0006] 2. The existing chemical dyeing mainly relies on the adsorption and fixation between the dyeing group and the fabric fiber, and this process has a high dependence on the structure of the fiber, so for different fabric materials, different dyeing methods need to be used together For example, nylon fabrics are mainly dyed with acid dyes, acrylic fabrics are mainly dyed with cationic dyes or disperse dyes, acetate fabrics are mainly dyed with disperse dyes, and sometimes insoluble azo dyes, so the universality of the pigments is poor.

[0007] 3. Traditional dyeing is mainly colored by liquid dyes. There are great differences in the degree of shrinkage and curling of fabrics with different weaving methods. Therefore, for fabrics with different weaving methods, the equipment used for dyeing is also different.

However, because this coloring technology only uses the periodic titanium dioxide and silicon dioxide film layers to interfere with light to produce color, the final color types are greatly limited; The thickness is extremely sensitive, and it is difficult to achieve the ideal yield in actual production, so there are great restrictions on the industrialization of this coloring technology; in addition, this coloring technology cannot guarantee the color fastness of the fabric

[0010] At present, there are also a small number of literatures that use vacuum deposition technology to deposit other metal elements or even alloys on the surface of fibers to slightly increase the richness of colors, but this method is limited to a few special fiber colors such as carbon fibers and polyimides. , but it is not suitable for traditional cotton, silk and other fibers, mainly reflected in uneven coloring of colored fabrics and no film deposition in some areas, resulting in color fastness that cannot meet the national standard
