The antimicrobial textile standard system is undergoing its largest update in nearly 20 years. In June 2025, the revision task for the national standard 'Evaluation of Antibacterial Performance of Textiles Part 2: Absorption Method' was officially assigned, with plan number 20251603-T-608. Earlier, the revision of Part 3 (Oscillation Method) was initiated in June 2024 under plan number 20241952-T-608, and has now been completed and is in the approval stage. This means that the antibacterial evaluation system covering underwear, socks, home textiles, sportswear, and medical textiles is about to undergo a comprehensive technical upgrade.
Event Background
The current GB/T 20944 series, published between 2007 and 2008, includes three parts: agar plate diffusion method, absorption method, and oscillation method. Over the past two decades, antibacterial technology has evolved from simple silver ion finishing to photocatalysis, microencapsulation, and other novel processes. Testing equipment and laboratory capabilities have also improved significantly. However, the old standards now lag behind industrial practice in terms of test methods, application scope, and technical requirements. This revision is not a partial patch but a recalibration of the entire evaluation logic.
In terms of revision pace, Part 3 was completed first, followed closely by Part 2, and while no timeline has been announced for Part 1, the path toward serialized updates is clear. The drafting units include testing institutions, research institutes, brand companies, and new material enterprises, reflecting a multi-stakeholder approach that balances academic advancement with industrial feasibility. For buyers, the standard update implies that existing test reports for antimicrobial fabrics may face a transition period; they should confirm the applicable version with suppliers in advance.
Industry Impact
The direct effects of the standard revision manifest at three levels. First, the scientificity and comparability of test results will be significantly enhanced. The old absorption method's parameters for bacterial strain selection, inoculum volume, and culture conditions deviate from the characteristics of current mainstream antibacterial materials, leading to discrepancies between actual efficacy and labeled claims. The new standard will adopt test conditions closer to real usage scenarios, compressing the space for conceptual hype and allowing companies with genuine technical strength to gain market premiums.
Second, corporate compliance costs and marketing risks will rise simultaneously. The revised standard imposes stricter requirements on functional labeling, making vague marketing tactics unsustainable. For foreign trade enterprises, special attention must be paid to the alignment between the new national standard and international standards. If export destinations use ISO 20743 or AATCC 100, differences with the new domestic standard may affect mutual recognition of test reports, so it is advisable to specify testing methods in order contracts.
Third, upstream new material enterprises will benefit from higher technical barriers brought by the standard upgrade. Suppliers of antibacterial finishing agents and functional fibers will need to provide more detailed performance data to help downstream pass the new standard tests, which in turn will accelerate the elimination of low-efficiency antibacterial agents and increase industry concentration. For home textile and sportswear brands, the revision is an opportunity for product differentiation; products that complete new-standard testing early can more easily build quality trust.
