Scope

This document describes the evaluation method for the antibacterial properties of textiles containing artificial (metal/metal oxide) nanomaterials (TCMNM), including the experimental process of testing the release amount of nanomaterials from textiles after washing and/or exposure to artificial sweat, and the evaluation methods for the antibacterial, antifungal, and deodorizing properties of TCMNM.
This document is applicable to textiles, yarns, and fibers that use artificial nanomaterials in the production or processing process.
This document is not applicable to textiles with therapeutic applications, nor does it address environmental, health, and safety (EHS) issues related to TCMNM. Additionally, this document does not consider the release of nanomaterials from TCMNM due to aging, drying loss, and wear, although these processes are also considered as a factor affecting the release of nanomaterials.
