A national standard implemented for nearly two decades is undergoing a systematic overhaul, and this change will directly reshape the rules of the antimicrobial textile market. In June 2025, the revision task for Part 2 (Absorption Method) of the series was officially assigned under plan number 20251603-T-608, and the subsequent review meeting held in Zhejiang marked a critical milestone. Meanwhile, Part 3 (Shake Flask Method) has completed its revision and entered the approval stage under plan number 20241952-T-608. This indicates that within the next two years, China's antimicrobial textile evaluation system will undergo a comprehensive transformation.
Background
The current GB/T 20944 series consists of three parts: Part 1 (Agar Diffusion Method, 2007), Part 2 (Absorption Method, 2007), and Part 3 (Shake Flask Method, 2008). These standards have provided a foundational framework for the regulated development of antimicrobial textiles over the past two decades. However, the application scenarios have expanded from initial underwear and socks to sports apparel, medical textiles, and home furnishings. The emergence of new materials and processes has challenged the applicability and accuracy of existing test methods.
The pace of revision reflects a sense of urgency among standard setters. The Part 3 revision task was assigned in June 2024 and entered approval just one year later; the Part 2 revision task was assigned in June 2025, with the review meeting held shortly thereafter. Such speed is uncommon in national standard revisions, highlighting the accumulated tension between industrial needs and technological progress.
Industry Impact
The revision will have direct transmission effects along the supply chain. For antimicrobial agent suppliers, changes in test methods may alter the logic for determining antibacterial effectiveness, thus affecting raw material selection and formulation design. For fabric and garment manufacturers, the revised standards will improve test reliability but may also increase compliance costs, especially for companies relying on concept-based marketing.
More importantly, the revision will reshape market competition. Previously, some companies exploited loopholes in the standards to exaggerate claims, making it difficult for consumers to distinguish genuine products. After implementation, unified evaluation methods will reduce such practices, giving truly functional products a competitive edge. For foreign trade enterprises, the coordination between Chinese standards and international ones will also affect mutual recognition of test results, potentially lowering trade barriers.
From an industry-wide perspective, the antimicrobial textile market continues to grow, but the lack of a unified scientific standard has been a lingering concern. This revision is not only a response to technological progress but also a strategic layout for the next decade. The broad participation of testing institutions, research institutes, brand companies, and new material enterprises indicates that the revision has gathered industry consensus, laying a solid foundation for future implementation.
