Rajoo introduces machinery for PP non-wovens

E

The company says segments such as automotive, medical, personal care and hygiene, home furnishings, household, stationery, agriculture and geotextiles would be the early adopters and enjoy the benefits resented by use of nonwovens as: fabrication speed and flexibility; the ability to slit in both directions without fraying; ability to be heat sealed /seamed/folded/shaped in a variety of ways and the possibility of ultrasonic welding.

For medical applications the company says PP non-wovens offer not only high absorbency and air permeability but also do not adhere to a wound ensuring a skin-friendly micro-climate. In furniture and textile applications, non-wovens excel in terms of their look, permeability and abrasion resistance. The structure and low weight of acoustic non-wovens offer significant advantages in perforated ceiling systems when compared to conventional sound proofing systems. Non-wovens in horticultural protect plants against temperature extremes by day and night, thus creating a foundation for earlier harvests with excellent results. In addition to being air and water permeable, they can be UV stabilised and are resistant to rotting.

In window treatments, non-wovens are used to design windows for enhanced functionality and appearance. Their ability to diffuse light while maintaining room brightness enhances the feeling of privacy and helps protect furniture. Their natural insulating ability helps in energy conservation. "This partial list of ever growing applications is a clear signal of the fast acceptance of this fabric, primarily due to its unique properties," says Rajoo.

The company says that the spun bonded process direct extrusion followed by online thermal web bonding is a popular process.

The Rajoo solution, built on a similar line includes a primary extruder, trim recycling extruder, automatic screen changer, melt pump, Barmag, spinnerets, filament cooling, fibre quenching, web forming and thermal bonding. It also has winding, slitter re-winder, chillers, vacuum furnace, ultrasonic cleaner and a touchscreen control panel.
