Embodiment 1

[0023] The singeing process uses clean energy natural gas to perform open-width open flame singeing to remove hairiness on the surface of the cloth;

[0024] The scouring and bleaching process adopts a continuous open-width scouring and bleaching method, which adopts immersion under the drum liquid and spraying with a water knife on the liquid to perform countercurrent rinsing.

[0025] The specific process is:

[0026] 1. Knitted cloth weight: 500 kg, cloth length about 1000 meters;

[0027] 2. Singeing: (vehicle speed: 50 meters per minute) total time: 20 minutes;

[0028] 3. Cooking and bleaching: (Liquid retention rate: 80%, speed: 25 meters per minute, 40 minutes in the steamer)

[0029] Total time spent: 40 minutes

[0030] Recipe: Total consumption:

[0031] Scouring agent 5 g / l 2 kg

[0032] Hydrogen peroxide stabilizer 3 g / l 1.2 kg

[0033] Chelating dispersant 3 g / l 1.2 kg

[0034] Hydrogen peroxide 30g / L 12kg

[0035] Caustic soda 8 g / l 3.2 kg

[0036] Reve...

Abstract

The invention relates to a continuous color knitted jean fabric pad dyeing process. The process comprises the following working procedures of cloth knitting, singeing, scouring and bleaching, dyeing, combining and finishing, and finished cloth obtaining. An open-width open fire singeing method is adopted in the working procedure of singeing. A continuous open-width scouring and bleaching method is adopted in the working procedure of scouring and bleaching, and countercurrent flushing is carried out through under-liquid soaking and up-liquid spraying by means of a drum; the rolling and drying process is adopted for dyeing in the working procedure of dyeing, an evenness calender is used for padding dye on cloth, and a steam drying cylinder is utilized for drying the cloth. According to the process, in the whole process, the open-width continuous production process is adopted, the production working procedures are reduced or combined, the problem that sulfur dyestuff color series can not be used for needle dyeing and cloth knitting of a rope-like dyeing machine for many years is solved, and the low-emission and low-energy-consumption continuous color knitted jean fabric pad dyeing process is achieved.

Description

technical field [0001] The invention relates to a continuous color knitted denim fabric pad dyeing process. Background technique [0002] In the printing and dyeing industry of knitted fabrics, traditional knitted fabrics usually adopt rope dyeing process, the steps include: boiling and bleaching, cleaning, hair removal, rinsing, dip dyeing, rinsing, soaping, rinsing, color fixing, softening and shaping, etc. This kind of rope dyeing process has disadvantages such as complex dyeing process, long process time, low production efficiency, low dyeing rate, and large amount of polluted waste water, which brings a great burden to environmental governance. Textile dyeing factories have also become environmental protection in some areas. The key targets targeted by the department have restricted the comprehensive competitiveness of our country's textile and garment industry to a certain extent. [0003] On the other hand, the rope dyeing machine is only suitable for dyeing sulfur b...
