Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example, wind and waterproof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources, and the materials can end up in the environment if handled improperly. …

The Swiss company Livinguard has developed a treatment for textile facial masks that can directly inactivate bacteria and viruses

Coatings and treatments at the fiber level are primarily utilized as a process aid. These ingredients can be used to heat stabilize the fiber while it is spun and stretched. They can also make the fibers easier to convert into the final fabric, and they can even be washed away during the process. Meanwhile, coatings, …

Nolla Silver Polymer: Crystal-clear liquid polymer contains 7,500 to 120,000 ppm of active silver and is highly effective against viruses, bacteria and fungi.

A Finnish company has developed an antimicrobial technology designed to eradicate highly resistant and dangerous pathogens, including the top five on the World Health Organization’s list of dangerous bacteria.

The new Nolla technology is also applicable for fiber coating, explained Jyri Nieminen, chief executive officer of Nolla Antimicrobial.

The technology is based on ionic silver, which is the most potent antimicrobial form of silver. An intelligent polymer carrier is used to preserve and deliver the silver ions.
