ANTI-BACTERIAL EXECUTIVE SUMMARY

Transcription

1 ANTI-BACTERIAL EXECUTIVE SUMMARY All antibacterial test results were conducted using the AATCC Method 100 standard testing protocol for textiles. All testing showed consistent performance for both gram negative and gram positive model organisms at greater than 5 log (99.999%) efficacy having been demonstrated consistently. The treatments robust and long lasting performance is demonstrated with greater than 5 log reductions after extended shelf life and wash cycle testing for up to 100 wash cycles. Several textile types are also shown with a focus on synthetic fabrics which are more prone to microbial growth such as polyesters. Testing was also conducted on textiles treated via standard industry treatment practices in international fabric mills. GENERIC APPAREL TEXTILE TEST RESULTS Results shown indicate greater than 3 log (99.9%) reduction in growth No CFU found in testing of treated textiles indicating a complete kill Both gram-positive and gram-negative model organisms tested Textiles treated with 2.5% of binder coating TEST ORGANISMS STAPHYLOCOCCUS AUREUS ATCC 6538 KLEBSIELLA PNEUMONIAE ATCC 4352 CONCENTRATION OF BACTERIA (CFU/ML) 1.3X X105 THE NUMBER OF BACTERIA RECOVERED FROM / AT 0H CONTACT TIME (CFU/SAMPLE) AT 24H CONTACT TIME (CFU/SAMPLE) SAMPLE 1.0X X102 CONTROL SAMPLE 1.2X X107 SAMPLE 1.2X X102 CONTROL SAMPLE 1.4X X107 REDUCTION (%) > 99.9 > 99.9

5 ANTI-FUNGAL EXECUTIVE SUMMARY Trichophyton testing used AATCC Method 30 Test 3 as testing protocol to identify efficacy while Candida results came from AATCC Method 100. Fungal efficacy was demonstrated with 4x higher binder applications than bacterial results which are more economical for textiles which are likely to develop fungal growth. These applications may include athletic footwear, textiles which are in contact with the groin, and other textiles which have consistently high moisture levels they are exposed to.

8 ECO-FRIENDLY EXECUTIVE SUMMARY Eco-friendly product certification has been conducted via OEKO-TEX for the GENESIS binder system. The following certificate was provided to certify the products environmental stewardship characteristics. The certification process includes both a chemical review for regulated and harmful chemicals included in the product. The review looks at a provided formula for chemical review as well as performing analytical test to look for traces of regulated or harmful chemical compounds.
