Abstract

The invention discloses a dyeing method for wool top. The dyeing method comprises the following steps: (1) sequentially adding benzyl benzoate, azobisisobutyronitrile, vinyl trimethoxy silane, dibutyltin dilaurate and vegetable dye in a dyeing jar, adding deionized water, uniformly stirring, and heating to 45 DEG C; (2) then sequentially adding aromatic polyether sodium benzenesulfonate, dodecyl dimethyl betaine, blocked isocyanate and beta-aminopropionic acid, continuously stirring until fully and uniformly stirring, and heating to 60 DEG C; (3) soaking the wool top in the dyeing jar for 50 minutes; (4) drying the soaked wool top at 85 DEG C; (5) soaking the dried wool top in clear water and rinsing for 50 minutes; (6) taking out the rinsed wool top and naturally drying. According to the dyeing method disclosed by the invention, the dyed wool top has excellent color fastness, the dyeing uniformity is good, and no dyeing defect exists.

Description

technical field [0001] The invention relates to a method for dyeing wool tops. Background technique [0002] In the existing method for dyeing wool tops, the color fastness of the dyed wool 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 tops, the dyed tops have excellent light fastness, washing fastness, dry cleaning color fastness, rubbing fastness, perspiration color fastness, water stain Color fastness, 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 method for dyeing wool tops, comprising the steps of: [0005] 1) Add 1 to 2 parts by weight of benzyl benzoate, 1.1 parts by weight of azobisisobutylcyanide, 0.7 parts by weight of ...
