Textile Stenter Machine
Textile stenter machine parts are very important to complete the whole stente process. The steps process using stenter frame and relax dryer and compactor. The damp fabric runs through the relax dryer (no pins) at a fast speed because the fabric has only 30% water content. Fabric comes out dry at 68-70″. The Maintenance Department performs the preventive maintenance task as per the schedule. Refer to Maintenance Specification for details.
Stenter Frame
Stenter frame – 5 chamber (could be more or less but settings below would change) run at 230-260 degrees fahrenheit (normally running at 330-350 degrees f) 45-50 yards/min. The knit fabric is dyed in tubular form, then slit. The fabric goes into the stenter frame wet at 60-63″. The fabric is put on pins and needs to be stretched by 10-15 inches. This means that the wet fabric is put on the pins and then opened up by 10-15 inches into the stenter frame. If the fabric is not pulled open enough, it will not get the torque out of the fabric. Very important: fabric should exit stenter frame with 30% water – still damp
Relax dryer
Relax dryer – 3 chamber
Run at 280-300 degree fahrenheit (normally running at 350 degrees f)
45-50 yards/min
**test**before the compactor, the fabric can be tested for torque and shrinkage to see if there are any problems. We test for torque by making 3 boxes across the fabric to see what the average is (see attached picture). This test is important. The torque at this point should be very low, under 3%. If it is not, the fabric wasn’t pulled open enough on entry to the shrink dryer or there is a knitting issue. **the length shrinkage should be 6-7% at this point. If length shrinkage is higher than this, the fabric wasn’t pulled open enough. If length shrinkage is greater than 6-7%, the compactor won’t be able to achieve the target shrinkage of 4×4% (5×5 is the specification). Very important: the fabric should be off-grain (not be strait) coming out of the stenter.
Compactor
The fabric then goes to the open width compactor. The fabric should be run natural through the compactor do not try to make the grain strait. The finished fabric should be off grain by about 8 inches out of the compator. The temperature on the compaction machine needs to be 104-115c (220-240 f) to create enough heat. Fabric is then rolled up.
Textile Stenter Machine Set-up
Machine set up for the Stenter machine is described below:
| Machine Parameters | Set-up Value |
| Padder Pressure | 2 to 8 bar (depends on the pick up requirement of the fabric.) |
| Temperature setting | (90-180)0C (according to the shade, quality and process of fabric.) |
| Blower fan setting | Low or high (according to the quality of fabric.) |
| Exhaust fan setting | Manual |
| Width of Textile Stenter Machine chain setting | 110 cm up to 260 cm (according to the required width of fabric.) |
| Overfeed | 0%-60% (as per the required weight of fabric.) |
| Burner gas pressure | 30-50 m/bar |
| Machine speed | 6 up to 60 m/m (according to the quality of the fabric.) |
| Light weight (100-140) gm/m2 | 20-30 m/m. |
| Medium weight (150-180) gm/m2 | 14-18 m/m. |
| Heavy weight (190-250) gm/m2 | 10-15 m/m. |
Response to Equipment Faults
Following are the response to be taken in case of equipment fault during Stenter machine process:
| Textile Stenter Machine Faults | Response |
| Pinning shoe problem | Mechanical Engineer should be called |

| Chain width disturbance | Mechanical/Electrical Engineer should be called |
| Burner, blower, motor problem | Mechanical/Electrical Engineer should be called |
| Padder, plaiter problem | Mechanical/Electrical Engineer should be called |
Machine /Area Cleaning
The daily and weekly cleaning works for Stenter Machine are described below :
- Clean the padder & rollers after complete every batch (when the next shade is different from the previous shade)
- Clean the sieves that can be reached from outside of the Textile Stenter Machine a minimum of once per shift.
- Clean the entire screen filter in every shift.
- Clean all the air ducts at least once a week.
- Clean the chemical mixing tank once a week.
- Clean all the buckets after every preparation of chemicals.
