Problem addressed

Coronaviruses are now shown to reside on textiles and garments for more than one day. Antimicrobial fabric treatments that are typically used do not demonstrate virucidal capability, and are not durable against multiple laundry cycles. It is essential to develop antiviral and antibacterial textiles with durable effectiveness.

  • In contrast to the traditional physical coating on fibers, NAMI’s washable antimicrobial textile is the result of surface modification of finished fibers with covalently bonded antimicrobial agents, having outstanding virucidal performance against viruses. 
  • The finish is durable against multiple laundry cycles, and will not change the color fastness and touch feel of the finished fabric.
Key impact
  • Washable with performance maintained over 30 home laundry cycles
  • Applicable to main stream colors of garments, with color fastness and touch feel maintained
  • Non-toxic, safe and green
  • Compatible with traditional manufacturing process, no alteration of workflow or purchase of additional equipment is required
  • Silver Medal at the “2022 Geneva International Exhibition of Inventions”
  • Garment products
  • Home textiles
  • Medical textiles
