A new polyester yarn that is both flame retardant and antimicrobial has been introduced by Sinterama.

The new yarn, GuardYarn, contains AlphaSan antimicrobial, a silver-based agent from Milliken & Company that inhibits the growth of micro-organisms that can cause odour and fabric deterioration.

AlphaSan is added during the extrusion process so that its antimicrobial characteristics can withstand repeated machine washings, dry cleanings or contact with normal chemical agents.
 
The new yarn has been created specifically for applications such as work wear apparel.

In addition to its antimicrobial features that prevent mildew and odour, GuardYarn has a high level of fire resistance.
