De-Watering Machine
The De-Watering machine plays an important role in the finishing section of the knit fabrics. A de-watering machine is used for reducing the remaining water of the wet fabric. It reduces the water content of the fabric.
Functions of De-Watering Machine And Their Parts:
De-watering machine has different parts and every single part has specific functions. Followings are de-watering machine parts names with their functions.
Spreader:
When the fabric is dyed in a dyeing machine it is found in rope form. After dyeing, when the dyed fabric is put in the basket it also remains in a rope position. By spreader, we can open fabric from the rope position. It can be spread and compressed in the width direction by its hydraulic cylinder.
Hand Wheel:
It is a manual process. It is used to guide the spreader.
Turn Tube:
Fabric rotation is controlled by the turning tube. It also helps in fabric feeding to the spreader.
Squeezing Roller:
It is the main part of the de-watering machine. The water of the wet fabric is squeezed by the squeezing roller.
Guide Wheel:
The guide wheel helps to feed the fabric into the squeezing roller.
Security Shield:
Security shield is an emergency switch settled with a plastic board very near to the padder. When it is close to the padder it is on and when it is pulled back then it is off. In case a big knot is going to pass the padder then it immediately pulls back the board to stop the machine. It is an automatic system to ensure the security of the padder. It helps to avoid any types of incidence.
Air Injection Switch:
It pushes air into the fabric to turn it into ballooning form. It helps to turn the rope from the fabric into open form.
Photocell:
Photocell is an auto sensor that controls air injection.
In sum, during the de-watering process, a softener is applied to the knit fabric. Also, various types of chemicals can be applied to the fabric by this de-watering machine. It is important to maintain uniform tension during operation otherwise GSM can vary in different parts of the fabric.
All above, it is important to know about the different parts of a de-watering machine. It also helps a textile engineer to be clear about a de-watering machine and its purpose of use.
