Completion process in fabric production

Finishing is the name of a set of different activities performed on fibers, yarns and fabrics to improve its properties or add new properties to it. The purpose of the final finishing operation on the fabric is to increase the quality of the fabric and attract the customer’s attention.
Types of fabric finishing process
Preliminary completion: Preliminary completion of this operation is as preparing the fibers to enter the spinning or preparing the fabric to enter the printing or dyeing. These operations include:

– Scouring: which is for wool fibers. Because the wool is very dirty and stinky after being arranged.

– Carbonization: In addition to fat, raw wool has some thorns and debris that are not separated from the fibers by washing the wool. With the help of a strong acid, thorns and chips and fatty substances in wool are hydrolyzed and become charcoal. And by shaking the fibers, the impurities fall off.

– Fabric washing: Fabrics that are produced in the weaving section are generally somewhat dirty and oily and should be washed. To be ready to take the next steps.

Intermediate finishing: The operation of intermediate finishing of the fabric includes completions that give the fabric new properties. Some of these additions include: Steaming the yarn to stabilize the warp, and Bleaching to stabilize the color. In this process, the fabric is bleached with bleach to make it look better, or dyed and printed on. They are better done. Mercerizing This operation is done only on cotton fibers for better absorption of materials and dyes. Concentrated caustic soda is placed on cotton for a short time and washed quickly.

Final Finishing: Final Finishing This group of finishes is used when the fabric goes through the final stages of production and is then packaged and sold. Chlorination of wool to prevent the appearance of dampness and ugliness of the appearance of flame wool fabric (Flame Resistance) fabric or yarn to be more resistant to fire or fire spread. Watter Proof Repellent In this operation, water penetration into the fabric is reduced.
Fabric width stabilization, light bleaching and even embossing can be considered as this type of completion. After the whole operation has been done on the fabric, the fabric is carefully examined once and after grading in terms of quality, it is packaged and marketed.
