Denim fabric is courser than usually woven fabric. Generally, courser yarn is used for making denim. After dyeing and weaving, denim fabric is sent to the finishing section for adding some properties to the fabric. In the finishing section; a sequence of production procedures is maintained.
Process Flow Chart Of Finishing Section In Denim Industry
The finishing process is performed in the following sequence. They are-
Grey Fabric Roll at Feeding Scray
Gas Singeing (2-Burner)
Dryer-1 (10 Cylinders)
Stenter (Except stretch denim)
Cooling Roller and Folder
List of Machines used in Finishing of Denim Fabric
In sum, to perform this operation various machine is used. I like to give a list of machine brand names which could be used in this process.
This is the first machine that is used at the beginning of finishing. The Brand name of the machine is Sperotto Rimer, which is manufactured in Italy.
In singeing unit; hairy fiber is removed. To perform this Osthoff-Senge singeing machine is used which is manufactured in Germany.
Padder Pressure (Air Pressure):
During padding following parameter is maintained.
- 7000 Kg (for stretch denim)
- 2000 Kg (except stretch denim)
After passing machine-1, fabrics passed machine-2. Here the following machines could be used.
- Sanforizing unit manufacturer- MONFORTS (Germany)
- Up to the dryer unit manufacturer- KTM (USA)
- General output speed- 50 m/min.
- Used chemical- Softener (Belsoft). Mixing tank contains 1200 Liter of softener solution which requires 20 kg softener for 1200 Liter.
So, this is all about the finishing section of the denim industry but the process sequence and machine types could be different depending on the demand end product requirement.
