Loop dyeing is a way of dyeing the fabric. This is a modern and widely used technology in which the yarn bath in a single dye instead of several baths. The machine used for it takes lesser space as compared to other dyeing method machines making it easier to use the rest of the space for other purposes. Loop dyeing was first introduced for dyeing denim and since then, it is used today for different dye fabrics around the world. Loop dyeing has lots of advantages that make it the most popular dyeing process in the textile industry There are lots of dyeable fabrics which are dyed by this technology and people can get fabulous printed fabric due to such dyeing technologies. 

This dyeing process requires less space as compared to other dyeing technologies. In this dyeing process, the yarn is dyed in a single bath as compared to several baths in other techniques. The desired color is obtained by passing the yarn from the vat several times. It includes running ropes of yarn through an indigo dye before releasing them into the factory’s roof to oxidize before returning them to the yarn bath. It is very much similar to slasher dyeing. To get the deeper shades, the sheet is dipped 3-4 times in the same dye bath.

List of machinery used in loop dyeing

The loop dyeing technique was developed by Echardt Godau in his company Looptex. The process is under the license of other companies such as Texima SA and Kusters Zima corporation which market their products under the loopdye brand name. For a compact layout, the machine is functioning with Looptex technology Nitrogen Indigo Dyeing Reactor. It can produce different color shades such as topping and sulfur bottoming. According to the company, thanks to the nitrogen atmosphere and the reduced lengths, loopdye can dye in half of the space with the machine and obtain better color shades with very good color fastness. The short layout of the machine allows for reducing water, hydrosulfite, and energy consumption. The company also claims that the machine is the cheapest in its category and simplest which enables it to operate by small skilled employees.

Advantages of Loop Dyeing Technology

Loop dyeing technology was a great innovation and addressed and fix some problems of dyeing fabric faced by earlier processes like slasher dyeing and rope dyeing. So, let's have a look at its advantages:

The fast dyeing process ensures that you can use the machine output to the fullest, allowing you to increase overall factory output keeping production costs in control.

Low investment cost

Due to the advanced technology and less space needed for the machine, loop dyeing technology does not need heavy investment and can install at a lower cost. Some other dyeing machines requires heavy investment and are also not as much productive as compared to loop dyeing machine.

Lower energy cost

The energy cost and maintenance costs of the loop dyeing machines are also lower as compared to slasher dyeing and rope dyeing technology. With large production, you also save the cost of production. So, if you are considering dyeing, think about loop dyeing technology.
