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:

Classification Textile Fiber

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)
