Antibacterial and stain-resistant finishes as the first barrier in passenger protection

01/06/2020

With passenger safety and public health under constant threat, let's see what types of finishes can help prevent new COVID-19 infections, keeping trains safer and cleaner.
The antibacterial finish

This type of treatment creates a strong barrier that hinders both bacterial and viral penetration, allowing lasting hygienic freshness and prolonged comfort. Being bound to the fibre, this finish acts on the cell membrane causing it to decompose.

 

The stain-resistant finish
It gives tissues hydrophobic properties and low moisture absorption, making it more difficult for microorganisms to attach to its surface. The surface becomes easier to clean and improves its hygienic properties.
How do you get hydrophobic properties?

The process consists of interpenetrating the molecular structure of the surface, thus preventing the penetration and deposit of water, or other liquids, as well as organic and synthetic oils and lubricating greases, while maintaining the complete breathability of the substrate, if this is the case.
The operating principle is based on the use of titanium dioxide in the anatase phase which, when irradiated with UV or sunlight, will develop photocatalytic and superhydrophobic photo-induced properties, therefore the change in the cohesion angle occurs thanks to the absorption of light.

To this principle is connected the concept of self-cleaning of the material: the water drops remaining intact on the surface will roll downwards, clinginging during their descent all the dirt deposited on the surface taking it away with it.
Gesa Industry in turn is committed to the battle against the Covid-19 by taking every possible measure to ensure the health of its employees and maintain complete contact with customers to ensure the right support and efficient assistance on every occasion.

Hydrogen railway: is it time to convert?

Natural gas could become a key element in the journey towards a hydrogen economy. A particularly good example of the technological advances being made in hydrogen production came from the Karlsruhe Institute of Technology in Germany. Researchers at the institute are developing a new method to separate hydrogen from natural gas using a liquid metal […]
