Fabric dyeing machine - Jigger

Fabric dyeing machine 

There are certain types of machines that are used for the fabric dyeing process.

1. Jigger dyeing machine
2. High-temperature jigger dyeing machine
3. HT vacuum jigger dyeing machine
4. Winch dyeing machine
5. High-temperature beam dyeing machine
6. Pad dyeing machine
7. Jet dyeing machine
8. Soft overflow jet dyeing machine

Jigger Dyeing Machine

As depicted in Figure, the jigger includes a chrome steel vessel within the shape of a V for holding the dye liquor, two top guide rollers, two immersion rollers at the underside, and two draw rollers for drawing fabric through the dye liquor. 7. 

On one of the draw rollers, 500–1000 metres of material are wound. This fabric could also be made from five or six separate lengths of material that are temporarily stitched together. 

The suitable dye liquor is then added to the V-shaped vessel, which is subsequently heated employing a perforated pipe at the underside of the jigger to the required temperature (depending on the procedure and also the variety of fabric being processed). 

The fabric's free end is fed down into the dye solution, around the guide rollers, and onto the second draw roller where it's tightly twisted to stay the material between them taut and freed from wrinkles. 

When the machine is turned on, the material is drawn by the second draw roller, which is currently the driven draw roller. 

When the whole cloth roll travels from the primary draw roll into the dye liquor and is then wound onto the second draw roll, one "end" is alleged to possess been completed. 

Another "end" is then created by feverishly the machine so that the primary draw roller becomes the driven roller and therefore the fabric returns to the dye solution to be wound onto the primary draw roller. 

The material can acquire more and more dye fluid because of this forward and backward movement. 

The fabric is periodically examined for shade to determine whether the death is From time to time the cloth is checked for shade to see whether the dyeing is Following the dyeing process, the vessel is cleaned off the dye fluid and full of cold water.

The material is threaded onto a draw roller, from which it will be removed for drying or the other treatment, and rinsed thoroughly within the overflowing water through as many ends as are necessary to clean it freed from the colouring chemicals. 

Each passage of the material typically takes about 10 minutes, thus the bulk of the death occurs when the material is on one or more draw rollers and is saturated with the dye fluid. 

In a typical dying cycle, the material is often cycled through a minimum of six ends. The procedure and therefore the style of dye will, however, change this. the kind of fabric being processed and also the size of the batch of materials affect how long the dyeing process takes overall. in an exceeding jigger, the M: L ratio is usually 1:5 or less. 

High-temperature jigger dyeing machine

The more contemporary jiggers have shorter dye tubes with a sharper V-shape and are manufactured from chrome steel. during this instance, the liquor ratio is significantly decreased. 

When sulphur dyes or vat dyes are accustomed to colour cellulosic fibre materials, reducing agents such as sodium hydrosulphite and sodium sulphide must be used, which increases the price of dyeing because continual exposure to air causes the chemical agent to be rapidly destroyed. 

The temperature rise to 110°C improves the outcomes when disperse dyes are wont to dye polyester utilising the carrier method. In these situations, enclosed jiggers are also employed. 

For inspection reasons, lids with sufficient glass windows are offered. a selected reasonably jigger is depicted in the image above.

These days, HTHP jiggers with dyeing capacities up to 1500 kg/7000 m and low liquor ratios as low as 1:2 are available. The dyeing temperature ranges from 140 to 143°C. 

HT vacuum jigger

This is another modified version of the standard jigger. Its salient features are
1. The vacuum slot used to suction the dye through the fabric makes it easier to dye because it ensures that the dye completely penetrates the woven fabric. 
2. Water usage has been reduced by 75%. It is therefore practical to use. The wastewater will also be greatly reduced.
3. It moves at a swift 200 metres per minute.
4. By maintaining a nitrogen-filled atmosphere inside the machine throughout the dyeing process, eliminates the issue of oxidisation during vat dyeing. By using this feature, 50% less hydrosulfide is consumed. Denmark and the Netherlands-based Henriksen produce HT vacuum jiggers.
