Embodiment 1

[0042] Embodiment 1: A salt-free pad-steaming continuous dyeing method for reactive dyes is formed by using the following dyeing method through padding, steaming, washing, soaping, washing, and drying. The ratio of the dye solution is as follows:

[0043] Type M reactive dye 5%

[0044] Pingping plus O 0.1%

[0045] Color-fixing alkali agent 2%

[0046] Water 92.9%

[0047] The dyestuff is an M-type reactive dye, that is, a chloro-s-triazine and a β-hydroxyethylsulfone sulfate dual active group. The color-fixing alkali agent is CJ-R produced by Yongji Wanxiang Company, and its main component is a mixture of sodium carboxylate and caustic soda. The leveling agent is Pingpingjia O produced by Shanghai Auxiliary Factory, the main component is fatty alcohol polyvinyl ether, and the molecular formula is: C n h 2n+1 (OCH 2 CH 2 ) m Oh.

[0048] Padding temperature: room temperature, steaming temperature: 100°C-102°C, time: 90 seconds.

Embodiment 2

[0049] Embodiment 2: A salt-free pad-steaming continuous dyeing method for reactive dyes, which is obtained by using the following dyeing method, through padding, steaming, washing, soaping, washing, and drying. The ratio of the dye solution is as follows:

[0050] Type M reactive dye 8%

[0051] Pingping plus O 0.15%

[0052] Color-fixing alkali agent 3%

[0053] Water 88.85%

[0054] The dyestuff is an M-type reactive dye, that is, a chloro-s-triazine and a β-hydroxyethylsulfone sulfate dual active group. The color-fixing alkali agent is CJ-R produced by Yongji Wanxiang Company, and its main component is a mixture of sodium carboxylate and caustic soda. The leveling agent is Pingpingjia O produced by Shanghai Auxiliary Factory, the main component is fatty alcohol polyvinyl ether, and the molecular formula is: C n h 2n+1 (OCH 2 CH 2 ) m Oh.

[0055] Padding temperature: room temperature, steaming temperature: 100°C-102°C, time: 90 seconds.

Abstract

The present invention relates to a continuous saltless pad-steam dyeing method with reactive dyes, which belongs to the novel technical field of textile printing and dyeing. After being singed, desized, boiled, bleached and mercerized, the half-finished product of cellulosic fibre woven fabric is dyed in the process of the continuous dyeing technique of padding, steam fixation, water washing, soaping, water washing and drying by the reactive dyes. The half-finished product of the preprocessed cellulosic fibre woven fabric is produced by pad dyeing, steaming and water washing, wherein, dyeing solution is composed of M reactive dyes, leveling agent, fixation alkali agent and water, and the mixture ratio is as follows: M reactive dyes: 0.01 percent to 10 percent, leveling agent: 0.1 percent to 0.2 percent, fixation alkali agent: 1.5 percent to 4 percent, and water: balance. The method is different from the conventional continuous dyeing technique of padding, drying, padding and steaming, which uses reactive dyes, and also different from the shortened wet-steaming technique with reactive dyes. On the conventional continuous padding machine, the novel method can fulfill the whole process of reactive dyeing without a hot-air padding machine and only with a developing and soaping range, thus greatly saving energy and reducing cost.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a salt-free pad-steaming continuous dyeing method for reactive dyes. technical background [0002] The existing conventional reactive dye padding, drying, padding and steaming process is a five-step process, namely: rolling, drying, rolling, steaming, and washing. This kind of process route is long and the cost is high; there are many process control points, and the probability of quality problems is high. [0003] 1. In recent years, the printing and dyeing industry is facing the following situation: [0004] ·There are many dyeing colors, and the processed varieties are continuously increasing; [0005] Requires textiles to achieve higher fastness properties; [0006] ·Products require fast delivery; [0007] ·Environmental protection regulations are becoming more and more stringent; [0008] Significantly reduced processing batches; [0009] ·Overcapa...
