China Indigo Slasher Dyeing Range supplier

Short Description:

1、Due to multi-tank process engineering, the continuous warp yarn dyeing machine can also be used for topping or dyeing with different categories of dye, such as Sulpher, Direct, Reactive, Naphthol, Pigment or Indanthrane dyestuffs. This is done with help of using additional tanks or bypassing certain tanks.

2、While using different type of Dyestuffs, it is important to match the immersion time and dye iquor quantity of different Dyestuffs. Adjustable immersion rolls also help in meeting the required immersion time, liquor quantity, number of squeezing, etc. to get the required depth of the Dye shade.

3、The present trend of Denim has shifted from a traditional 14 oz Denim to lighter Denims for fashion and casual ware. Processing of such light Denims need flexible approach to meet fast changing fashions. With the help of multi-tank concept, it has become possible to go in for continuous multi-color warp dyeing – cum – sizing plant. This helps us to optimize the use of Dyes / Chemicals in Denim plant turning out to be economical and echo friendly.

Principles for slasher indigo dyeing

1. Yarn is first prepared (by ball warping machine for rope dyeing, by direct warping machine for slasher dyeing) and start from the beam creels.
2. Pre-treatment boxes prepare (by cleaning & wetting) the yarn for dyeing.
3. Dye boxes dye the yarn with indigo (or other types of dye, such as sulfur).
4. Indigo is reduced (as opposed to oxidation) and dissolved in the dye bath in the form of leuco-indigo in an alkalic environment, with hydrosulfite being the reduction agent.
5. Leuco-indigo bonds with yarn in the dye bath, and then brought into contact with oxygen on the airing frame, leuco-indigo reacts with oxygen (oxidation) and turns blue.
6. Repeated dipping and airing processes allow indigo to gradually develop into a darker shade.
7. Post-wash boxes remove the excessive chemicals on the yarn, additional chemical agents may also be used at this stage for different purposes.
8. sizing process is done right after dyeing on the same machine, final beams are ready for weaving.
9. Productivity-wise, a slasher dyeing range usually has about HALF the production capacity of 24 / 28 ropes dyeing range.
10. Production capacity: About 30000 meters yarn by a slasher dyeing range.
