Viscose Fabric Dyeing Process In 2022 (Update)

The viscose fabric dyeing process is so sensitive process in the dyeing industry. Viscose is regenerated cellulosic fiber. Its strength is not as good as cotton fiber. As a result, it needs extra care during processing. It is famous for its end uses. The soft hand feel and glossy effect make itself famous. viscose dyeing with reactive dyes because it is a cellulosic fiber. let’s discuss the process.

The knitted viscose fabric dyeing process is discussed below:

Viscose dyeing process step by steps:

Anticreaseing agent + Oil remover inject= Inject

Raise Temp to 70⁰C

Load fabric

Runtime 5min

Soda ash light dissing 7min

Runtime 10min


Scouring chemical inject = Detergent+anticreaseing agent+ secquestering agent

Soda ash light dossing 7min

Raise the temperature to 70⁰C

Hydrogen Peroxide inject

Raise the temperature at 80⁰C

Runtime 15min

Cooling at 75⁰C

Shade check (Brightness)


Raise temperature To 70⁰C
