Dyeing process of 100% cotton

Complete Dyeing process of 100% cotton fabric
The original way of wet processing is most important. Follow chart is part and parcel in textile industry. This is ideal follow chart for cotton dyeing which is help somebody to know about cotton fabric or yarn dying.

I’m describing the complete dyeing process of 100% cotton fabric by the following process flowchart:
Fill water

Load fabric

Temperature control 600 C

Inject detergent + Sequestering agent + Anti-creasing agent

Run time 10 minute

Caustic dosing 600C X 10’

Increase temperature at 700C

H2 O2 dosing

Run time 110 0 C X 40’

Cooling at 800 C

Rinse at 60 0C for 7 minute

Water drain

Fill water and inject PKK

Temperature 980 C and run time 10’

Cooling at 800 C

Rinse at 50 0C for 7 minute

Water drain

Fill water

Inject acetic acid at 550 C X 10’ and check p H

Raise temperature at 800 C X 10’ and destroy enzyme activity

Rinse for 5 minutes

Water drain

Fill water

Check p H

Temperature 600 C

Inject leveling + sequestering agent run time 5’

Inject salt 600 C X 20’

Color dosing 60 0C X 33’

Run time 20 minute

Soda ash dosing for 33’

Check sample after 10, 33.…… during shade matching

Rinse at 50 0C for 15’


Fill water

For neutralizing, inject A. acid

Run time 10 minute then rinse for 10 minute


Fill water


A. Acid 55 0C X 10’

Check PH

Inject softener

Run time 500C X 20’



Fill water

Cold wash

Unload from machine

Classification Textile Fiber

Click here to visit Textile Student

We can say that fiber is the base of all textile goods and this is the only platform where textile industry depend directly. Because it is the main raw material of  every kind of textile goods. Every single textile goods are comes from any of textile raw material whatever it's natural or synthetic. a Textile Student should know the definition and classification of finer to explore student's knowledge about textile technology.
Basically there are three kinds of fiber on the basis of origin most of the people says regenerated fiber is a material which is a combination of natural and man made or synthetic fiber. Let's have a look on textile fiber. 

1-Natural fiber
2-Synthetic fiber
3-Regenerated fiber

(1)Natural fiber : Natural fiber is the most popular and most comfortable fiber around the world. Natural fiber is come from nature like various animal and trees. E.X.(cotton. just,wool) natural fiber is friendly with human skin and nature. natural fiber is cultivation in field so its helps us to reducing the global worming and green house gas. 

(2)Synthetic fiber ::These Fibers are from chemical base production, by too many different chemical are makes synthetic fiber. Because we can collect synthetic fiber as we need. Sometimes goods from synthetic fiber are not comfortable to use so we . And also risky nearby to fire.synthetic fiber make a little pollution and its not friendly with nature. like natural fiber this syntactic fiber never completely mixed with nature.E.X.(polyester, glass fiber)

(3)Regenerated fiber:: We can't get regenerated fiber directly because regenerated fiber are comes from both of  natural and synthetic fiber. We have to follow some steps to get fiber. First we get fiber polymer from wood, bamboo etc.Yearn from regenerated fibers are also used to making fabric. regenerated fiber's raw material comes from nature but its will not be able to use until its process with different chemical and make it useable. It's are not harmful to nature. Also comfortable to use. (e.x. Rayon)
