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