Scope: This document specifies the requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for antibacterial towels. This document applies to antibacterial towels made from natural fibers, chemical fibers, and blended fibers. Main technical content: Antibacterial towels are divided into four antibacterial grades (AA to AAAA) based on the number of wash cycles and the inhibitory rate of bacteria. The evaluation indicators for the inhibitory rate of test strains are shown in Table 1. **Table 1: Inhibitory Rate Indicators for Antibacterial Towels** Antibacterial Grade Number of Wash Cycles Inhibitory Rate (%) Staphylococcus aureus Escherichia coli or Pseudomonas aeruginosa AA Grade 20 cycles ≥84 ≥74 AAA Grade 50 cycles ≥82 ≥72 AAAA Grade 50 cycles ≥85 ≥75 AAAAA Grade 50 cycles ≥88 ≥78 Note: According to the product's intended use, additional test strains may be added or adopted, and the number of wash cycles and inhibitory rate indicators shall be agreed upon separately by the supplier and the buyer.
