Abstract

The invention discloses a wool fabric dyeing method, which comprises: 1) sequentially pouring hexamethoxymethylmelamine, maleic acid, polyacrylic acid, dinitroso pentamethylene tetramine and a plant dye into deionized water in a dyeing vat, uniformly stirring, and heating to a temperature of 55 DEG C; 2) sequentially adding iminodipropionic acid, tributyl phosphate, hexanediamine and methacrylic acid diethyl amino ethyl ester, continuously stirring until completely and uniformly mixing, and heating to a temperature of 65 DEG C; 3) soaking a fabric for 25 min in the dying vat; 4) drying the soaked fabric at a temperature of 80 DEG C; 5) immersing the dried fabric in clear water, and rinsing for 25 min; and 6) taking out the rinsed fabric, and carrying out natural air drying. According to the present invention, the dyed fabric has advantages of excellent color fastness, good dyeing uniformity, and no dyeing spot.

Description

technical field [0001] The invention relates to a method for dyeing wool fabrics. Background technique [0002] In the existing wool fabric dyeing method, the color fastness of the dyed fabric is not high, the dyeing uniformity is not good, and color flowers are easy to occur. Contents of the invention [0003] The object of the present invention is to provide a dyeing method for wool fabrics, the dyed fabrics have excellent color fastness to chlorine bleaching, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, color fastness to sunlight, perspiration, etc. Color fastness, color fastness to water stains, color fastness to non-chlorine bleaching, and good dyeing uniformity, colorless flowers. [0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of dyeing method of woolen fabric, comprising the steps: [0005] 1) Add 1 to 2 parts by weight of hexamethoxymethyltrihydrogenamine,...
