Healthcare associated infections cause millions of hospitalizations and cost billions of dollars every year. A potential solution to address this problem is to develop antimicrobial textile for healthcare fabrics hospital bedding gowns lab coats etc.. Metal nanoparticle-coated textile has been proven to possess antimicrobial properties but have not been adopted by healthcare facilities due to risks of leaching and subsequent loss of function toxicity and environmental pollution. This work presents the development and testing of antimicrobial zinc nanocomposite textiles fabricated using a novel Crescoating process. In this process zinc nanoparticles are grown in situ within the bulk of different natural and synthetic fabrics to form safe and durable nanocomposites. The zinc nanocomposite textiles show unprecedented microbial reduction of 99.99 4 log10 to 99.9999 6 log10 within 24ampnbsph on the most common Gram-positive and Gram-negative bacteria and fungal pathogens. Furthermore the antimicrobial activity remains intact even after 100 laundry cycles demonstrating the high longevity and durability of the textile. Independent dermatological evaluation confirmed that the novel textile is non-irritating and hypoallergenic.
