Denim fabric is courser than as usual woven fabric. Generally courser yarn is used for making denim. After dyeing and weaving, denim fabric is send to the finishing section for adding some properties to the fabric. In finishing section; a sequence of production procedure is maintained.
The finishing process is performed as the following sequence.
Grey Fabric Roll at Feeding Scray

Brushing
↓
J-Box
↓
Gas Singeing (2-Burner)
↓
Brushing
↓
Chemical Box
↓
Squeezing Padded
↓
Skew Roller
↓
Dryer-1 (10 Cylinders)
↓
Rubber Belt
↓
Stenter (Except stretch denim)
↓
Palmer

Cooling Roller and Folder
To perform this operation various machine is used. I like to give a list of machine brand name which could be used in this process.
Machine-1: This is the first machine which is used in the beginning of finishing. The Brand name of the machine is Sperotto Rimer, which is manufactured in Italy.
Singeing unit: 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)
Machine-2: After passing the machine-1, fabrics passed the machine-2. In here 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 all about the finishing section of denim industry but the process sequence and machine types could be different depending on the demand of end product requirement.
I am a textile engineering student.I am doing a project on "effect of different types of softener on the quality of denim dyed fabrics".Could you please give me some information regarding this.
