ISO/TS 23650 discusses nanotechnologies that specify the antimicrobial performance assessment method of textiles containing manufactured (metals/metal oxides) nanomaterials (TCMNMs). The textiles in ISO/TS 23650 include fabric, yarn, and fiber in which manufactured nanomaterials are used during the production or finishing process. Further, ISO/TS 23650 also specifies protocols to determine the number of nanomaterials released from textile following washing and/or exposure to artificial human body sweat.
ISO/TS 23650 only covers the antibacterial, antifungal, and anti-odour performance assessment method of TCMNMs.
ISO/TS 23650 does not cover textiles that have therapeutic applications as well as environmental, health, and safety (EHS) issues related to TCMNMs. Further, it does not cover the release of nanomaterials from TCMNMs because of aging, dry attrition, and abrasion, although it is considered an effective factor in releasing nanomaterials.
ISO/TS 23650 on nanotechnologies is useful for-
The utilization of nanotechnology in the textile industry has presented novel functions such as antimicrobial activity, stain resistance, flame retardancy, mechanical strength enhancement, UV resistance, and wrinkle resistance into the conventional textiles without significant loss or change of the original properties.
ISO/TS 23650 provides assessment methods, protocols, and antimicrobial assessments i.e., characteristics of metal or metal oxide, metal or metal oxide release measurement, determination of antimicrobial activities, and protocols to determine the number of nanomaterials released from textile washing and/or exposure to artificial human body sweat for TCMNMs that gives an understanding for release of nanomaterials.
When fabric goes under different conditions sweating, mechanical stresses (repetitive abrasion) during the washing process in a laundry machine helps to understand the potential releases to the environment.
