Wet Processing Technology
Wet processing technology and its uses are huge in the textile sector. The dyeing process for different textile materials could be different but its basic idea is the same for all. For all types of dyeing, pre-treatment is a must for removing unwanted materials from textile materials. Pre-treatment style differs for the shade of dyed materials. The shade may be light or deep. Also, this pre-treatment depends on the buyer’s requirement. After pre-treatment textile materials are ready for dyeing. After dyeing after treatment is necessary to get the final finished products. At last, that’s product becomes ready to use. This sequence can be expressed by a flow chart.
Process Flow Chart of Dyeing Textile Materials
Basic Flow chart of dyeing textile materials is like the followings:
Grey Textile Materials (Fiber, Yarn, or fabric)
Desizing (For woven fabric)
Now I like to discuss shortly the different terms of the flow chat. Here, grey textile materials are fiber, yarn, or fabric which is also considered the raw materials for dyeing.
Basic Structure of Wet Processing Technology
Singeing is the first step of pre-treatment. The process by which loose, hairy, and projecting fibers are removed is called Singeing.
Desizing is the second step of pre-treatment. Through this process, gummy materials are removed. Also, size materials are removed by this process.
Scouring is the third step of pre-treatment. This process is performed for removing impurities from the textile materials.
Bleaching is another important step that is used to reduce the natural color of the raw materials. Dyeing performance depends on it much more.
Mercerizing is a special type of treatment. It performs if the buyer wants. Moreover, it is an additional treatment. It increases the strength and luster of the materials.
Dyeing is the main process where a white material becomes decorated with different colors. We have to know about the depth of shade of the materials.
Printing is called localized dyeing. Different types of printing are done for giving a special appearance to the colored or white fabric.
Finishing is the last treatment of wet processing. Different types of properties can be added to the materials by different finishing effects.
Marketing is our main goal. Say, if we have done everything but there have no buyer then everything is a waste. So we should have a strong marketing department.
So, all of this is about a flow chart of Dyeing.
