A national standard for evaluating antimicrobial textiles, in effect for nearly two decades, is undergoing a systematic overhaul. In June 2025, the revision of Part 2 (Absorption Method) was officially assigned with plan number 20251603-T-608, while the revision of Part 3 (Shake Flask Method) had been initiated a year earlier under plan number 20241952-T-608 and has now been completed, entering the approval stage. This means two of the three core method standards in the GB/T 20944 series will be fully updated within the next year or two, reshaping the technical foundation of the antimicrobial textile industry.
Background
The current GB/T 20944 series, published between 2007 and 2008, consists of three parts: Part 1 Agar Diffusion Method, Part 2 Absorption Method, and Part 3 Shake Flask Method. Over the past two decades, antimicrobial technology has expanded from initial applications in underwear and socks to sportswear, home textiles, and medical textiles, making antimicrobial function a key differentiator. Meanwhile, new materials and processes have emerged, and testing capabilities have advanced significantly. The limitations of the old standards in terms of test methods, scope, and technical requirements have become increasingly evident, making revision imperative.
The review meeting held in Zhejiang focused on Part 2 (Absorption Method), attended by members of the basic standards subcommittee of the National Textile Standardization Technical Committee and representatives from participating organizations. The revision task was issued in June 2025, and this meeting marks substantial progress. Notably, the drafting units include testing institutions, research institutes, brand enterprises, and new material companies, reflecting broad industry consensus.
Industry Impact
The revised standard will adopt test methods better aligned with technical advancements over the past two decades, improving accuracy and reproducibility. For buyers, this means more reliable determination of antimicrobial performance and fewer disputes caused by methodological differences. For manufacturers, a unified and scientific standard provides clear technical guidance, helping to standardize R&D, production, and functional labeling, thereby reducing disorderly competition driven by exaggerated claims.
A deeper impact lies in rebuilding market trust. Antimicrobial performance is invisible and intangible; consumers rely on test reports to make decisions. If standards lag, the market is prone to "fake antimicrobial" products, harming consumer rights and damaging industry reputation. A revised system will enhance the credibility of authoritative test results, turning antimicrobial function into a verifiable quality label rather than a marketing gimmick.
From a supply chain perspective, the revision will transmit upstream to raw material suppliers. Producers of antimicrobial fibers and finishing agents will need to adjust technical indicators and promotional language according to new methods, while downstream brands must re-test products and update compliance filings. In the short term, some companies may face higher testing costs, but in the long run, scientific standards will accelerate the elimination of technologically backward and data-inflated players, driving industry consolidation.
Practical Recommendations
For Buyers - Monitor standard revision updates and update antimicrobial acceptance clauses in procurement contracts to reference the latest GB/T 20944.2 or GB/T 20944.3. - Require suppliers to provide test reports based on new methods, and be wary of those still using old standard data. - Incorporate scientific validity and traceability of test methods into supplier evaluation criteria.
For Foreign Trade Companies - Compare differences between domestic new standards and international ones (e.g., ISO 20743, AATCC 100) for export markets, adjusting testing plans to reduce trade barriers. - Use the transition period to retest existing products to avoid customs clearance issues due to standard changes. - Maintain close communication with testing agencies to obtain proficiency testing information for new methods, ensuring lab results are accepted by overseas clients.
Every revision of a standard is a measure of the industry's technical level. The update of the GB/T 20944 series not only responds to two decades of antimicrobial technology development but also lays the groundwork for future industrial upgrading. With Part 3 nearing approval and Part 2 under review, the antimicrobial textile industry stands at a new starting line—and the way this line is drawn will determine the competitive landscape for the next decade.
