Finishing of 100% cotton woven fabric with Anti-Crease finish.

Textile finishing is two types one is a chemical process and the other is a mechanical process. Anti-crease finishing often known by various fancy terminologies is an important process of textile processing. Resin finishing is known as Wash & Wear Finish or Anti Crease Finish or Crease Resistant Finish or Durable Press Finish and Wrinkle Free Finish. Resins are cross-linking agents, which form a covalent bond on reaction with –OH groups of cellulosic materials in an acidic medium at a pH of 3-4. The cotton cellulose chain contains –OH groups in both Amorphous and Crystalline regions. There are Hydrogen Bonds between the –OH groups of the molecular chains. after the load is applied to the cotton fabric chain of the cellulosic in fiber bend and remains permanent.

Nature Of sample: 100% cotton woven fabric.

Apparatus required: i) Beakers. ii) Glass Rod. iii) Pipette. iv) Measuring Cylinder. v) pH meter.        vi)Pot. vii) Electronic Balance

Process Sequence:

 Recipe: 

 Anti Crease Finish=15 g/L

Wetting Agent= 2 g/L

Temperature=  Normal Temperature

                  pH=

Carrying Temperature= 130°c

Time = 7 min

The function of the chemical:
Anti-creasing agent: Prevents creasing of fabric or garments. The anti-creasing agent is one of the cross-linking agents.

  Working Procedure:

1. Firstly we take the fabric sample and chemicals.
2. Then we measured the chemicals by digital balance.
3. Then we prepare the solution of chemicals.
4. After preparing the chemical solution we drop the sample and take time.
5. After some time we take a sample from the chemical solution and prepared it for padding.
6. We padded the sample for five (5) times at a normal temperature.
7. After padding, we take the sample and prepared the sample for carrying.
8. In the carrying machine, we dry the fabric sample for 7 min at 130°C.

Precaution:

1. We have to maintain the laboratory precaution very carefully.
2. Every chemical we take should be taken accurately by pipette and should be taken very carefully.
3. We should be very careful during the time of working with a gas burner.
4. We should have to maintain the temperature accurately.
