The antimicrobial textile market is at a new threshold. The national standard "Textiles - Evaluation of Antibacterial Performance - Part 2: Absorption Method" recently passed a review meeting in Zhejiang, signaling a clear shift in the evaluation system. For buyers and manufacturers, this means testing thresholds, promotional claims, and even product development directions will need to adjust.
Background
The review meeting was organized by the Subcommittee on Basic Standards of the National Textile Standardization Technical Committee, with participants from testing institutions, research institutes, brand companies, and new material enterprises. Notably, the revision task for Part 2 was issued in June 2025 (Plan No. 20251603-T-608), while Part 3 (Shake Flask Method) started earlier in June 2024 (Plan No. 20241952-T-608) and has already entered the approval stage. The simultaneous revision of two parts indicates a systematic effort to harmonize testing methods.
The GB/T 20944 series has been in effect for nearly 20 years. During this period, antibacterial technologies have evolved from traditional silver ion and chitosan to photocatalysis, nano-composites, and microencapsulation. Applications have expanded from underwear and socks to sportswear, medical textiles, and home textiles. The old standards are no longer adequate for evaluating new antibacterial materials.
Industry Impact
The revision directly affects the credibility of test results. The absorption method and shake flask method are designed for different types of antimicrobial agents (leaching and non-leaching). The updated methods will better simulate real use conditions, reducing discrepancies between lab results and actual performance. For buyers, this means more comparable test reports, but also requires re-evaluating suppliers' testing capabilities.
Another significant effect is compliance risk in marketing. Antimicrobial functionality is invisible, and the market has long suffered from exaggerated claims. After the new standard is implemented, companies using old test data or vague claims like "99% antibacterial rate" may face compliance issues. Brands and exporters should review product labels and promotional materials in advance.
From an industry upgrade perspective, the revision will accelerate the elimination of outdated production capacity. Testing laboratories will face new challenges, and those capable of multiple methods (shake flask, absorption, agar diffusion) will gain more orders. Antimicrobial agent suppliers will need to adjust formulations to ensure stable performance under stricter test conditions.
