Problems solved by technology

Although this method can achieve the improvement of the dye uptake rate of the cloth, the effect of fading of the denim after dyeing is improved, but the steaming temperature of the inventive method is higher, and after steaming, it needs to be soaked in sodium bicarbonate solution. Soak for a long time

Abstract

The invention provides a denim printing and dyeing method. The denim printing and dyeing method comprises the following steps that printing and dyeing paste is prepared, and a printing and dyeing auxiliary is added in preparation; ultrasonic pretreatment is performed on the printing and dyeing paste, and a grey cloth is dyed; the dyed grey cloth is aged at the temperature of 100 DEG C-105 DEG C for 10 minutes; the cloth is soaked in a sodium bicarbonate solution for 3-5 hours; aftertreatment is performed, and dyeing is completed. The printing and dyeing auxiliary is prepared from, by weight, 5-8 parts of guar gum, 10-15 parts of poly-alkyl propionic acid esters, 25-30 parts of sodium carboxymethylcellulose, 10-15 parts of octadecyl dimethyl benzyl ammonium chloride, 4-6 parts of tannin and 5-9 parts of barium chloride. According to the method, by adding the auxiliary, denim can be printed and dyed at the low ageing temperature of 100 DEG C to 105 DEG C on the condition of 3-5 hours of short-time sodium bicarbonate solution soaking, the color fastness of the denim can be promoted to 4-5 level, and discoloring in washing is reduced.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and relates to a denim printing and dyeing method. Background technique [0002] In daily life, we often encounter the phenomenon of clothing fading, especially the fading phenomenon of denim clothing is more common. When exposed to the sun, saliva or physical friction, the dyes are easy to fall off and fade, affecting the appearance, and the fallen dye molecules or heavy metal ions may be absorbed by the human body through the skin and endanger health. [0003] CN104074065A discloses a denim printing and dyeing method, comprising the following steps: gray cloth pretreatment, printing paste preparation, dyeing and printing, soaping, water washing, and drying steps, which are characterized in that after the printing paste preparation is completed, the printing paste is subjected to ultrasonic Pretreatment for 30-60 minutes, then printed by a printing machine, steamed at 115°C for 10 m...
