The way a fabric is dyed is called process flowchart of wet processing technology. Actually some of the steps of a dyeing process can be removed or added as per buyer requirement. Suppose your buyer wants the more precised dyed fabric; so in this fact you should mercerize your fabric during the dyeing pre-treatment process. Basically if the buyer don’t want that so called particular fabric there is no need to mercerize your fabric.
The dyeing or wet processing flow chart is given below.
Before dyeing a fabric or yarn some pre-treatment and after treatment is needed. A flowchart is drawn here by combining these:
This is the most widely used wet processing flow-chart on the contemporary textile industry. But sometimes on some factories the scouring and bleaching is done simultaneously. Here is a brief description of every process steps i have mentioned in above Dyeing flowchart:-
Gray Fabric Inspection: In this step all of the gray and already colored fabric is separated. Mainly we will work with the gray fabric is to make this colored in our next process.
Sewing or Stitching: If the fabrics are in part or in separate segments; then we have to bring these all together by stitching or sewing.
Singeing: Singeing is the process to remove or burn the protruding fibers over the cloth. While weaving a fabric; some protruding fibers is created at the surface of the fabric and we should remove these short fibers before further dyeing processing.
Desizing: At the beaming section of making a Fabric we uses various starch and sizes to make the warp yarn more stronger. But while we planned to make this fabric colored we have to remove the applied starch and sizes as it might causes negative reaction with colors and chemicals.
Scouring: The main objective of Scouring process of wet processing technology is to polish the fabric service by rubbing it hard or cleaning the surface and brighten it.
Bleaching: Bleaching process is one of the crucial process of Dyeing as it helps to gray fabric brighter than usual.
Mercerizing: Mercerizing is a costly process but due to buyer requirements we might have to give the fabric extra luster and brighter appearance.
Dyeing: After mercerizing the cotton or fabrics; this is the time to apply dye along with chemicals. Dyeing process is a broad topic and it is discussed in another category of this textile blog.
Printing: While dyeing is conducted to put color in all over the body of the fabric; Printing is done in a specific zone of the fabric. A specified design is created on the fabric surface before printing application is manipulated.
Finishing: In the finishing department of this Wet processing Flowchart; the faults of fabrics, faults of dyeing is to be monitored and possible spots is to be fixed.
Final Inspection: After dyeing a fabric it is to be finally monitored and rechecked.
Dispatch or Delivery: This is the last sector of Deying department and in this stage the dyed fabrics is to be exported or sent to the buyers.
