Classification of dyeing processes based on production:
Table of Contents
The dyeing process can be divided into three parts based on the production. E.g.
1. Batch production
2. Semi-continuous production
3. Continuous production
1. Classification of dyeing processes based on production-Batch production:
Currently, most textile products are dyed in batch form; Such as in the form of yarn package, in the form of fiber and cloth, etc. There are different types of dyeing machines for dyeing these. The batch dyeing process is usually completed by dipping the product in a dye bath. Dyeing is done by transferring dye from the dye bath to the product. In this method, the production at dyeing is less.
The following points are important for balanced dyeing in this method.
a) Keep the product in the machine carefully.
b) Aim to ensure that the operation of the liqueur is correct.
c) To take measures so that the dyeing is not completed quickly.
2. Classification of dyeing processes based on production-Semi-continuous production:
This method requires a lot of products for large-scale production. This procedure is usually done in three steps.
a) Impregnation
b) Storage
c) Washing
a) Impregnation:
Impregnation can usually be done in two ways. E.g.
# Padding
# Spraying
In the padding process, the product is taken through the dye solution. Again in the spraying method, the dye solution is sprayed directly on the product.
b) Storage:
After impregnation, the dyed product is stored for a while at a low liqueur ratio.
c) Washing:
After storage, the dyed product is washed to remove the loose dye on the product. This washing can be in batch form or continuous.
3. Continuous production:
This method requires a lot of clothes. It also has a lot of production. In this method, different methods are used for different fabrics. In most continuous processes the product is heated so that it absorbs the dye quickly. The last step in dyeing in the continuous process is washing the product. In this method, the production is very high and the cost is relatively low. Again, this method requires a lot of clothes.
