100% Viscose Fabric Dyeing Method
Many times we got some inquiry from buyer for viscose fabric.
Thought this fabric has some advantage, but also it has so many disadvantages
which found in the dyeing process.
Viscose fabric is not a common fabric like as cotton. The
hand feelings of this fabric are same as silk & soft.
Viscose yarn is a kind of yarn which made from cellulose
base. Viscose is a type of man-made fiber but it is not a synthetic
fiber like as polyester, because it is made from natural materials, but it is
heavily processed.
Advantages of Viscose
Fabric which is made from viscose yarn is that takes dyes
very well, so that, we can work with a wide variety of colors. Viscose fabric
is very shiny; also it stays bright and colorful throughout the life of the
products made with it. So, if you want to work with various kind of bold and
colorfast fabric then you can choose viscose.
Disadvantages of Viscose fabric
1) Fabric
tearing possibility is very high during the dyeing process.
2) If the
fabric remain wet for long times then some spot creates on its, which removal
process is very difficult. But in cotton fabric we can do this very easily.
3) If the
fabric dyed uneven then it is very difficult to remove.
4) During the
dyeing process if we fail to maintain the temperature & pressure properly
then fabric strength will be reduce.

Dyeing Process of 100% Viscose Fabric:
Actually
viscose dyeing process is almost same as single jersey cotton spandex fabric.
However, please find below the dyeing process.

(detergent wash) the fabric in the dyeing winch and released the
water for perform the next process.

the fabric by labeling agent which increased the PH of fabric.

not require for white color fabric.

Now the fabric is ready for cutting. Please test the
Shrinkage, Color shade, Gsm before start cutting.
However, I always suggest everybody to avoid the order with
viscose fabric. Because dyeing of this is very risky & costly also.
