De-Watering Machine
In the knit fabric finishing process; a de-watering machine is used after passing the hydro-extractor machine. After hydro-extracting the fabric, the remaining water is removed by the de-watering process. During the de-watering process, an additional chemical is used to soften the fabric. Different types of operational parameters are controlled during the de-watering process.
Objectives of De-Watering Machine
Various types of objectives are achieved by the de-watering process. The following are the main objectives of the de-watering machine.
- Excess or remaining water is removed or reduce by the de-watering machine.
- In most of the cases, softener is applying during de-watering process.
- Apply overfeed to give some compactor.
- Fabric is open from the rope form.
- Width-wise stretch of the fabric is done.
- Fabric is turn into plait form by this process.
- GSM of the fabric is controlled during de-watering.
- To control the crease mark of the fabric.
Operational Parameter of De-Watering Machine
The following parameter is controlled during de-watering.
- Speed: As much as possible (40-60 m/min). Higher the GSM lower the speed.
- Over feed: As required. Higher the GSM higher the over feed.
- Padder pressure: 3-7 bar as required. Higher the GSM lower the padder pressure.
- Width: Fabric width is adjusted as per required width.
- Stretch: 8 to 12% minimum than the requirement of customer.
De-Watering Machine
Here, I have presented two de-watering machine brands with their profile.
- Brand name: Weiss
- Origin: Western Germany
- Pressure: 50 psi
- Speed: (60-70) m/min
Another,
- Brand name: Bianco
- Origin: Italy
- Pressure: 50 psi
- Speed: (60-70) m/min
Another famous brand is CALATOR BORAS, whose origin country is Sweden.
So, the de-watering machine has a great impact on the knit fabric finishing process.
