Parx Materials develops antimicrobial polypropylene nonwoven – nonwovens industry magazine

Start of antimicrobial additive Parx materials has successfully developed a new non-woven polypropylene (PP) material that is resistant to bacteria. Latest test results show the material to be effective against strains of E. coli, Staphylococcus and Candida Albicans, reaching a class AAA for use in medical masks, gowns, diapers or other sanitary products. .

The antimicrobial nonwoven material is made from polypropylene through the spunbond production method in which the woven materials are made in one continuous process. Thanks to Parx Materials’ Saniconcentrate technology, the material prevents bacteria and viruses from surviving without toxic biocides or leaching.

The new material will allow textile manufacturers to take advantage of the antimicrobial effects without harming humans or the environment – a vital step forward as the world demands increasing levels of hygiene for both personal protective equipment (PPE ) and personal property.

To prove the effectiveness of the nonwoven material against bacteria, efficacy tests according to the antibacterial standards of knits were carried out by SGS-CSTC Standards Technical Services (Shanghai). Before the tests, the material was washed 50 times.

The test report shows that after 18 hours the Parx Materials nonwoven sample had an efficacy of 90% against Candida Albicans, 99% against E.coli and over 99% against Staphylococcus Aureaus. An exceptional result proving the efficiency and longevity of the material.

The tests performed on the nonwoven material also included a disk diffusion test. This is a product safety test, measuring how well the antimicrobial effect migrates from the material after a wash. The sample material was placed in agar jelly and after 18 hours for E. coli and Staphylococcus and 48 hours for Candida, there was no bacteria-free halo surrounding the material.

This result far exceeds the safety requirement of a diameter less than or equal to five millimeters. This proves, unlike most antimicrobial materials out there, that there is no migration of Parx Material technology – better for humans, the environment and preventing bacterial resistance.

As a result of the test results, the nonwoven fabric received the highest possible class AAA antibacterial textile classification according to the FZ / T 73023-2006 Antibacterial Knitting Standard of the People’s Republic of China (PRC).

“Our technology can now be integrated into non-woven materials to prevent the spread of bacteria and viruses,” explains Michaël van der Jagt, CEO of Parx Materials. “But it can also be used to prevent odors, which are often caused by microbes – a useful USP for products like diapers. Since it stays just as effective for over 50 washes, it’s great for things that will be used over and over again.
