Antimicrobial properties incorporated in light-colored synthetic yarns and fibers

Everyone knows that the aim of checking into a hospital is to come out healthy again. Unfortunately, however, reported cases of hospital-acquired methicillin-resistant staphylococcus (MSRA) infections continue to make headlines. Such reports are the reason that the GRAFE Group has been working intensively on the development of antimicrobial and antibacterial treatment of plastics for more than 10 years.

Traditional solutions that work for thick-walled injection-molding and extrusion articles, such as incorporating nanosilver, copper and silver ions, or embedding oxide mediums are not suitable for all types of products. Not only does the performance vary, depending on the polymer, the environment and the application, the inherent color is also of great importance. These techniques result in a dark to light grey, which is difficult if not impossible to recolor. Considering the high costs created by the additional antimicrobial and antibacterial treatment of plastic articles in hospitals, rehabilitation centers and health facilities, it is understandable that customers do not wish to forgo the important aspect of color choice

 

In a search for a solution to this challenge, GRAFE has developed a process which eliminates some of these drawbacks. The patented development is aimed at the treatment of plastic parts and synthetic staple fibers which must be dyed in light colors. The substances used in the process are supplied by the Austrian company AMISTec located in Kössen, Tirol. Among the benefits are highly effective and long-lasting antimicrobial properties, a wide spectrum of activity and no induction of resistance. They are just as effective against multi-resistant pathogens such as MRSA, VRE and ESBL. The material contains no nanoparticles and is not inactivated by sweat or proteins.

Customers who are interested in participating in initial evaluation and implementation of this technology can take advantage of the service and support offered by GRAFE and AMISTec for initial sampling and lab testing of the antimicrobial treatment prior to series production.
