标准编号：ISO 20743:2021

中文名称：纺织品 纺织产品的抗菌活性测定

英文名称：Textiles — Determination of antibacterial activity of textile products

发布日期：2021-06

标准范围

本文件规定了测定所有抗菌纺织品（包括非织造布）抗菌活性的定量试验方法。本文件适用于所有纺织产品，包括用于服装、床上用品、家居用品和杂项物品的布、絮、线和材料，无论使用的抗菌剂类型（有机、无机、天然或人造）或使用方法（内置、后处理或嫁接）。本文件包括三种测定抗菌活性的接种方法:a） 吸收法（将试验菌悬液直接接种到样本上的一种评估方法）；b） 转移法（将试验细菌置于琼脂平板上并转移到标本上的一种评估方法）；c） 打印方法（将测试细菌放置在过滤器上并打印到样本上的一种评估方法）。注？根据预期用途和纺织产品的使用环境，以及纺织物的表面特性，用户可以选择最合适的接种方法。本文件还规定了菌落平板计数法和三磷酸腺苷（ATP）发光法，用于测量细菌计数。

This document specifies quantitative test methods to determine the antibacterial activity of all antibacterial textile products including nonwovens.This document is applicable to all textile products, including cloth, wadding, thread and material for clothing, bedclothes, home furnishings and miscellaneous goods, regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting).This document covers three inoculation methods for the determination of antibacterial activity:a) absorption method (an evaluation method in which the test bacterial suspension is inoculated directly onto specimens);b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto specimens);c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto specimens).NOTE            Based on the intended application and on the environment in which the textile product is to be used, and also on the surface properties of the textile properties, the user can select the most suitable inoculation method.This document also specifies the colony plate count method and the adenosine triphosphate (ATP) luminescence method for measuring the enumeration of bacteria.
