planarTECH Mask Utilising PureGRAPH® Enhanced Coating Durable through 100 Wash Cycles

Independent test laboratories prove that the 2AM™ graphene face mask from planarTECH, which uses PureGRAPH® in the novel textile coating retains its performance after 100 domestic wash cycles.  The product is a truly reusable mask, maintaining its bacteria resisting performance and appearance after 100 washes.

The 2AM™ flexible graphene coated polyester fabric used in the masks has been tested by the THTI (Thailand Textile Institute) to the specification Antibacterial Finishes on Textile Materials AATCCTM 100: 2012.  Staphylococcus aureus ATCC 6538 was used as the challenge bacteria.

The fabric test specimens were sterilised before testing using an autoclave at 121°C, 15 psi for 15 minutes.  Microorganism samples were introduced to the test specimen swatches and left for 24 hours and the number of bacteria remaining on the fabric is subsequently measured.  The coated fabrics were tested after 30, 50, 80 and 100 wash cycles in all cases a reduction in the level of bacteria of over 99.94% was recorded. The tests confirm the cutting-edge bacteria resisting properties of the PureGRAPH® coating developed by planarTECH.

Patrick Frantz, CEO of planarTECH says “This testing validates the durability of performance in our 2AM™ face masks which is enable by the unique properties of the graphene coating.”

Craig McGuckin, Managing Director of First Graphene Ltd. says “We are pleased that the performance of our PureGRAPH® graphene products continues to be independently validated in the market-leading 2AM™ masks”.
