Antibacterial Standard Revision Accelerates: Absorption Method Under Review, Two Decades of Tech Evolution Drives Evaluation System Upgrade

The antibacterial textile standard system is undergoing a critical iteration. In June 2025, the revision task for the national standard 'Textiles - Evaluation of Antibacterial Performance - Part 2: Absorption Method' was officially issued (plan number 20251603-T-608), followed by a review meeting in Zhejiang, signaling that this evaluation method, implemented for nearly two decades, is about to receive a systematic upgrade. Meanwhile, the revision of Part 3 (Oscillation Method) has entered the approval stage (plan number 20241952-T-608). The simultaneous progress of both standards signals a comprehensive restructuring of the industry's evaluation system.

Background of the Standard Revision

The GB/T 20944 series, released between 2007 and 2008, covers the agar plate diffusion method, absorption method, and oscillation method, laying the technical foundation for the standardized development of antibacterial textiles. However, over the past 20 years, the application of antibacterial technology in textiles has expanded from underwear and socks to sportswear, medical textiles, and home textiles. New antibacterial materials and processes have emerged, and the precision and efficiency of testing equipment have improved significantly. The original standards have gradually shown limitations in test methods, scope of application, and technical requirements, making it difficult to accurately reflect the performance of new antibacterial products and leaving room for conceptual hype and exaggerated claims.

The necessity of revision lies not only in technical adaptation but also in reshaping market order. Antibacterial performance is a functional indicator that consumers cannot directly perceive. Without a unified scientific evaluation scale, promotional claims across companies will be inconsistent, increasing the risk of bad money driving out good. Therefore, this revision is seen by the industry as a summary of the past two decades of technological progress and a forward-looking layout for future industrial upgrading.

Industry Impact

The revision's ripple effects on the supply chain are significant. For testing institutions, new methods will more closely simulate real-use scenarios, improving the accuracy and repeatability of results and helping establish a more authoritative third-party certification system. For manufacturers, the revised standards clarify technical indicators and test paths, making R&D directions clearer but also imposing higher demands on process stability and quality control. Brands relying on vague marketing concepts will face greater compliance pressure.

From the procurement perspective, brands in home textiles, sportswear, and medical textiles will rely more on test reports under the new standards when selecting suppliers. Antibacterial functionality will shift from a 'selling point' back to a 'quality attribute,' helping to reduce false claims and allowing companies with genuine technical strength to gain a premium. For foreign trade enterprises, the degree of alignment with international standards will affect export competitiveness. If the revised evaluation methods more closely match mainstream international practices, it could reduce technical disputes in trade barriers.

Practical Recommendations

For Buyers - Monitor the release of new standards and update supplier antibacterial performance acceptance criteria in a timely manner to avoid misjudgment based on outdated versions. - Require suppliers to provide third-party test reports based on the new standards, with a focus on verifying whether test methods, bacterial strains, and evaluation indicators match procurement needs. - Clearly specify acceptance criteria for antibacterial performance in contracts, and include buffer clauses during the standard transition period to mitigate compliance risks.

For Foreign Trade Enterprises - Map the antibacterial standards of target markets, compare the domestic revision direction with international standards such as ISO and AATCC, and adjust testing strategies in advance. - Maintain communication with testing institutions to understand the impact of new methods on sample preparation, culture conditions, and other details, avoiding deviations due to operational differences. - In export product promotions, strictly base functional claims on data obtained under the new standards to avoid trade disputes arising from improper advertising.
