Therefore, it is a main technical problem to be solved at present to provide a method for enhancing the color gamut of cellulose fiber or fabric dyed by plant extracts of three primary colors, which is convenient and easy to operate.
Disclosure of Invention
In order to solve the above problems, the present invention provides a method for enhancing the color gamut of a plant-extracted trichromatic dyed cellulose fiber and a fabric, comprising the following steps:
s1, modifying cellulose fibers or fabrics by using a modifying solution containing a quaternary amine group compound;
s2, dip dyeing and dyeing the modified cellulose fiber or fabric by using a three-primary-color plant extract solution;
s3, soaping and drying the dyed cellulose fibers or fabrics to obtain the dyed cellulose fibers or fabrics;
the cellulose fiber is selected from one or more of cotton fiber, viscose fiber, modal fiber, acetate fiber, lyocell fiber, tencel fiber and hemp fiber.
Preferably, the concentration of the quaternary amine group compound in the modifying solution is 3-12g/L.
Furthermore, the concentration of the quaternary amine group compound in the modification solution is 5-10g/L.
Preferably, the quaternary ammonium group compound is selected from one or more of (3-chloro-2-hydroxypropyl) trimethyl ammonium chloride, 2,3-dihydroxypropyl-trimethyl ammonium chloride, (3-acrylamidopropyl) trimethyl ammonium chloride, methacryloyloxyethyl trimethyl ammonium chloride, acryloyloxyethyl trimethyl ammonium chloride, trimethyl [3- (triethoxysilyl) propyl ] ammonium chloride, hydroxypropyl trimethyl ammonium chloride chitosan.

Preferably, the weight ratio of the modifying liquid to the cellulose fiber or the fabric is (4-20): 1.
in order to solve the problems of low dye-uptake of plant extracts to fabrics and poor antibacterial and anti-mite effects of fabrics in the prior art, the applicant unexpectedly finds that when quaternary amine group compounds are used for modifying fabrics, the weight ratio of the quaternary amine group compounds is 1: (1-2): (2-4) trimethyl [3- (triethoxysilyl) propyl ] ammonium chloride, (3-chloro-2-hydroxypropyl) trimethyl ammonium chloride and hydroxypropyl trimethyl ammonium chloride chitosan are used as quaternary ammonium group modifiers, the concentration of quaternary ammonium group compounds in the modification solution is controlled to be 3-12g/L, and the weight ratio of the modification solution to the cellulose fiber or fabric is (4-20): 1, on one hand, the color yield and dye uptake of the tricolor plant extracts on the surface of cellulose fibers or fabrics in the system can be improved; on the other hand, the durability of the effects of antibiosis, mite prevention and the like of the cellulose fiber or the fabric can be enhanced to a certain degree. The application guesses that the possible reason is that after the cellulose fiber or the fabric is treated by the modification solution containing trimethyl [3- (triethoxysilyl) propyl ] ammonium chloride, (3-chloro-2-hydroxypropyl) trimethyl ammonium chloride and hydroxypropyl trimethyl ammonium chloride chitosan, the modification solution can react with polyphenol, flavone, polyester and other active ingredients in the plant extract to improve the affinity of the plant extract and the cellulose fiber or the fabric, so that the color yield of active molecules in the plant extract on the surface of the cellulose fiber or the fabric is improved, meanwhile, the phenomenon that the active ingredients of the plant extract are easy to lose in the prior art is avoided, and the excellent dyeing effect is achieved, and meanwhile, the cellulose fiber or the fabric is ensured to have good antibacterial and anti-mite durability.

In order to further expand the dyeing color spectrum of the trichromatic plant extract on cellulose fiber or fabric and improve the color fastness of the trichromatic plant extract.
