The required effect cannot be obtained at all with the current conventional dyeing process of reactive dyes, while the conventional dyeing of old clothes uses cationic pretreatment, paint dyeing and then biological enzyme treatment to peel off the dye on the surface of the fabric. The process is complicated. It consumes a lot of water, and the effect of imitation is difficult to control, so this process cannot be used

Abstract
The invention relates to a cotton knitwear activated dye imitation old dyeing method which is characterized by including steps: 1) pretreatment of a gray fabric; 2) removal of wool; 3) dyeing of activated dyes; 4) treatment by the aid of sodium bicarbonate; 5) water washing after comparison between a sample and a dyed fabric; 6) treatment by the aid of glacial acetic acid; 7) taking out of the dyed fabric from a cylinder and dewatering of the dyed fabric; 8) dying; 9) product sizing at the temperature of 130 DEG C. The method changes a present situation that a conventional activated dye cannot make imitation old color, wool on the fabric surfaces is removed after the gray fabric is pretreated, the activated dyes are treated by the aid of the sodium bicarbonate after dyeing and washing with a soap, so that activated colors are in weakly-alkaline solution, the colors change dark under influential effects of temperature and time, the dyed fabric is circularly dried in a loop drying machine, so that the dyed fabric can mutually rub, fabric surfaces have whiting fuzzy effects, and finished products are sized by adding steam in a dry manner, and cotton knitted gray fabrics have imitated old feel.
Description
technical field [0001] The invention relates to a method for imitating old clothes dyeing of cotton knitted fabrics with reactive dyes. Background technique [0002] Cotton knitted gray fabric is sample dyed and processed. The gray fabric is 320 grams of 70 / 30 cotton-polyester terry cloth. The customer provides a sample fabric. The surface of the cotton is smooth, the lines are clear, and the color has an old-fashioned feel. This required effect cannot be obtained at all with the current conventional dyeing process of reactive dyes. According to the conventional dyeing of old clothes, the method of cationic pretreatment, paint dyeing and then biological enzyme treatment is used to peel off the dye on the surface of the fabric. The process is complicated. It consumes a lot of water, and the effect of imitation is difficult to control, so this process cannot be used. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the prese...
