Embodiment 1
[0021] A method for dyeing cotton cheese with dope, comprising the following steps:
[0022] Loose bobbin: by winder winding, the weight of a single bobbin of 20 or less coarse-count yarns is controlled at 0.7kg, and the density of a single bobbin of coarse-count yarns is controlled at 0.35g / cm;
[0023] Pre-treatment: Inject water into the dyeing vat, add 3g / L hydrogenperoxide with a concentration of 26%, 4g / L sodiumhydroxide with a concentration of 30% and 0.5g / L scouring agent with a concentration of 48%, then raise the temperature to 90°C and keep warm 30min, drain, inject hot water at 80°C, wash for 7min, then drain;
[0024] Yarn Modification: Steps After completion, fill the dyeing vat with water, add cationic modifier and solid caustic soda 6g / L, control the pH at 12, then raise the temperature to 75°C, keep it warm for 30min, drain, then wash with warm water at 60°C for 8min, drain, and then use normal temperature Wash with water for 8 minutes;

Embodiment 2
[0030] A method for dyeing cotton cheese with dope, comprising the following steps:
[0031] Loose bobbins: through winder winding, the weight of a single bobbin of 25 yarns is controlled at 0.68kg, and the density of a single bobbin of 35 yarns is controlled at 0.34g / cm 3 ;
[0032] Pre-treatment: Inject water into the dyeing vat, add 3g / L hydrogenperoxide with a concentration of 26%, 4g / L sodiumhydroxide with a concentration of 30% and 0.5g / L scouring agent with a concentration of 48%, then raise the temperature to 90°C and keep warm 20~40min, drain, inject hot water at 80°C, wash for 7min, then drain;
[0033] Yarn Modification: Steps After completion, fill the dyeing vat with water, add cationic modifier and solid caustic soda 6g / L, control the pH at 12, then raise the temperature to 80°C, keep it warm for 30min, drain, then wash with warm water at 60°C for 7min, drain, and then use normal temperature Wash with water for 7 minutes;

Abstract
A paint dyeing method for cotton cheese, comprising the following steps: (1) loosening the cone; (2) pretreatment; (3) yarn modification; (4) dyeing; (5) fixing and softening the color; (6) drying Dry. The dyeing method proposed by the invention has reasonable technology, simple operation, greatly saves water consumption and the use of raw materials, thereby effectively saving production costs. The residual dye is boiled away, the dyeing is uniform, the paint utilization rate is high, the quality of the yarn is improved, and the economic benefit is also improved.
Description
technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a paint dyeing method for cotton cheese. Background technique [0002] The existing dyeing scheme for cotton cheese basically uses reactive dyes and is dyed in a high-temperature and high-pressure cheese dyeing machine. Dye with direct or vat dyes sparingly. The above dyeing methods will consume a large amount of water, electricity and steam. The current average level is: water consumption is 100 tons of water / ton of yarn, power consumption is 1200 kWh / ton of yarn, and steam consumption is 3 tons / ton of yarn. And it will consume a large amount of chemical additives such as sodiumsulfate and soda ash, and the sewage treatment is difficult and costly. Reactive dyes for cotton lack the bright monochromatic colors with fluorescence. There is only one reactive fluorescent yellow dye, and the price is 6-7 times that of ordinary reactive yellow dyes. The paint just makes up ...
