The nonwoven material is made up of fibers like polyamide, polyester and viscose which tends to provide them the desired action of resilience, strength, toughness and capillarity for the squeezing. These fibers are then bound with a synthetic binder to make the material stronger.
The nonwoven sheet is firstly cut into circular discs according to the size of the roll and then pressed onto a solid steel shaft with the help of a hydraulic press. These discs are then secured with end plates. The shaft and material are secured with keyway which does not allows the movement of the nonwoven material while it is under pressure. Steel shaft is provided with the protective epoxy coating which helps it to resist the acidic and alkaline environment.
Efficiency and Savings:
The nonwoven rolls when subjected to load tends to gently press the fabric and squeeze out the water from its warps and wefts. This produces a lots of savings in the terms of chemical, steam/ gas on dryer etc. The average saving ranges from around 15-40% and in certain cases it has been found even more.
Advantages and benefits:
Nonwoven based rolls are primarily used for saving energy and can save around 25-40% annually.
The nonwoven rolls have high coating thickness due to which it can last long compared to an ordinary rubber roll.
These rolls are self-recovering and regain its shape due to minor damange caused by foreign materials. In case of high damage these can recover by the use of hot water also.
