Abstract

The invention discloses an acrylic fiber dyeing method. The method comprises (1) blending, (2) melting, (3) lamination and (4) drying. The acrylic fiber dyeing method has the advantages of smooth conversion rate and easy operation.

Description

technical field [0001] The invention relates to an acrylic fiber dyeing process. Background technique [0002] When dyeing traditional acrylic fabrics, the dosage of anionic dyes is 1.5%, retarder 1227 is 1%, and acetic acid is used to adjust the pH value of the dye bath to 4-4.5. The dyeing process adopts a step-by-step heating method, that is, after adding materials, the temperature is gradually raised to 86°C, kept for 15 minutes, and then heated to 100°C for 30 minutes. Although the operation is cautious, there are still color flowers. Contents of the invention [0003] The purpose of the present invention is to provide a kind of acrylic fiber dyeing process with the advantages of stable conversion rate and easy operation. [0004] The technical scheme of the present invention is: a kind of acrylic fiber dyeing process, the step of described acrylic fiber dyeing process comprises: [0005] (1) Ingredients: Weighing, removing iron, mixing and stirring various raw mat...
