Abstract

The invention discloses a dyeing method of wool fiber top, comprising the following steps: 1) successively adding tristyrylphenol polyoxyelhylene ether sulfonate, acryloyloxyethyltrimethyl ammonium chloride, polyvinylpyrrolidone, dimethyl formamide and vegetable dye into a dye vat and successively pouring deionized water, uniformly stirring and heating to 45 DEG C; 2) successively pouring N-methyldiethanolamine, linear alklybezene sulfonates, magnesium sulfate and nitrilotriacetic acid, continuously stirring until the materials are fully and uniformly mixed, and heating to 60 DEG C; 3) immersing top into the dye vat for 50 min; 4) drying the immersed top at 85 DEG C; 5) immersing the dried top in clear water and rinsing for 50 min; and 6) taking the rinsed top out of the clear water and naturally airing. The top dyed by the above method has excellent color fastness and has good dyeing uniformity and has no dyeing defect.

Description

technical field [0001] The invention relates to a method for dyeing wool fiber tops. Background technique [0002] In the existing method for dyeing wool fiber tops, the color fastness of the dyed tops is not high, the dyeing uniformity is not good, and colored flowers are easy to occur. Contents of the invention [0003] The purpose of the present invention is to provide a method for dyeing wool fiber tops, the dyed tops have excellent color fastness to sunlight, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, color fastness to perspiration, and water fastness. Color fastness to staining, color fastness to chlorine bleaching, 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 wool fiber top, comprising the steps: [0005] 1) Add 1 to 2 parts by weight of tristyry...
