Ultralow liquor ratio zipper dyeing machine and dyeing process thereof

Abstract

The invention discloses an ultralow liquor ratio zipper dyeing machine and dyeing process thereof. The dyeing machine comprises a tube cylinder, a cylinder cover and a zipper warp beam plate frame embedded into the tube cylinder. The zipper warp beam plate frame comprises a zipper plate seat, a hollow water drum, a zipper woven belt, a zipper tube sleeve, a locking bolt, and a zipper frame lifting ring. The lower end of the hollow water drum is fastened on the zipper plate seat, the zipper tube sleeve is sleeved on the outer side of the hollow water drum, and a diversion inlet and a diversion outlet are arranged below the zipper plate seat and connected with an infusion pump through a horn-shaped pipe sleeve. The dyeing process comprises the stages of scouring and bleaching, dyeing and water scrubbing. According to the ultralow liquor ratio zipper dyeing machine and the dyeing process thereof, a lift range required by zipper woven belt dyeing water level can be achieved when the height of dye liquor in the dyeing machine is lower than the zipper plate seat, the effect of ultralow liquor ratio zipper dyeing is achieved, the dyeing machine has a lower dying liquor ratio than a traditional zipper dying machine, and the purposes of saving electric energy, steam and the dye liquor, shortening dyeing and finishing periods, and saving energy and reducing emission are achieved.

Description

technical field [0001] The invention relates to a zipper dyeing machine, in particular to a zipper dyeing machine based on an ultra-low bath ratio and a dyeing process thereof. Background technique [0002] The disadvantages of the old zipper dyeing machine are large liquor ratio, high power consumption, many dyeing and chemical auxiliaries, and long process time. Dyeing one kilogram of zipper fabric requires more than 5 kilograms of water. In actual use, the zipper fabric is soaked in half a dye vat in the saturated state of water. In the dyeing process, the color yield of the zipper webbing is reduced and the dye permeability is poor, which is prone to defects such as color flower and color difference. Dyeing bath ratio is a very important index to measure the zipper dyeing machine. At present, the bath ratio is used to measure the zipper dyeing machine. The liquor ratio of the old-fashioned zipper dyeing machine is usually higher than 1:5, and the zipper dyeing machine...

AI Technical Summary

Problems solved by technology

[0003] At present, there are problems in domestic zipper fabric dyeing and finishing equipment: (1) The traditional zipper rack dyeing consumes a lot of water, and the bath ratio is higher than 1:5, which is higher than the ultra-low bath ratio zipper dyeing machine.

(2) The dyeing efficiency of zipper webbing is low and the process cycle is long (zipper webbing→winding zipper tube sleeve→installing zipper rack→boiling and bleaching→dyeing→sizing→dehydration→drying→winding), the old overflow zipper dyeing machine It takes about 6-8 hours to dye a cylinder of cloth, and the dyeing cycle is long, which takes 2-4 hours longer than that of foreign-made dyeing and finishing equipment.

(3) The pollution is large, and each tank of dyeing liquid requires a large amount of dye auxiliary

(4) Large water consumption. The old overflow dyeing machine consumes a lot of water per kilogram of fabric, which is about 47% more than the foreign-made dyeing and finishing equipment.

(5) Power consumption is large. The power consumption per thousand kilograms of fabric of the old overflow dyeing machine is about 47% more than that of foreign dyeing and finishing equipment.

[0005] The main pump is the power source of the dye liquor circulation, and its performance is directly related to the bleaching and dyeing effect. The head of the circulation pump of the zipper dyeing machine is a very important parameter for the quality of the dyeing machine. If the head is too small, the dye liquor cannot penetrate the zipper ribbon roll. The dyed zipper webbing has color difference and uneven dyeing, and the lift is too large to waste energy
