Main Technical Content: 5. Technical Requirements 5.1 Product Grading The products are divided into three grades: superior, first-grade, and qualified. 5.2 Performance items and indicators are shown in Tables 1 and 2. **Table 1: Performance items and indicators of circular antibacterial polyester staple fibers** **Serial No. Item Superior First-Grade Qualified** 1 Breaking strength (cN/dtex) ≥ 4.50 4.20 4.00 2 Breaking elongation (%) M1a ± 6.0 M1 ± 7.0 M1 ± 10.0 3 Line density deviation (%) ± 3.0 ± 4.0 ± 8.0 4 Length deviation (%) ± 3.0 ± 6.0 ± 10.0 5 Ultra-long fiber rate (%) ≤ 0.6 0.6 1.0 6 Ultra-long fiber content (mg/100g) ≤ 2.0 3.0 15.0 7 Defect content (mg/100g) ≤ 5.0 15.0 30.0 8 Crimping number (pcs/25 mm) M2b ± 2.5 M2 ± 3.5 9 Crimping rate (%) M3c ± 2.5 M3 ± 3.5 10 Dry heat shrinkage rate at 180°C (%) M4d ± 2.0 M4 ± 3.0 11 Specific resistance (Ω·cm) ≤ M5 × 108 12 10% tensile strength at elongation (cN/dtex) ≥ 2.80 — 13 Antibacterial rate / - Staphylococcus aureus ≥ 85 - Escherichia coli ≥ 80 - Candida albicans ≥ 75 a M1 is the center value of breaking elongation, selected from the range of 22.0–34.0. Once determined, it cannot be arbitrarily changed. b M2 is the center value of crimping number, selected from the range of 8.0–14.0. Once determined, it cannot be arbitrarily changed. c M3 is the center value of crimping rate, selected from the range of 10.0–16.0. Once determined, it cannot be arbitrarily changed. d M4 is the center value of dry heat shrinkage rate at 180°C, determined by negotiation between the supplier and the buyer. Once determined, it cannot be arbitrarily changed. e M5 is the specific resistance, selected from the range of 1.0≤M5<10.0. Once determined, it cannot be arbitrarily changed. **Table 2: Cross-shaped antibacterial polyester staple fibers performance items and indicators** **Serial No. Item Superior First-Grade Qualified** 1 Breaking strength (cN/dt
