Technical Q&A
Q: Antimicrobial efficacy decay pattern after washing?
A: Experimental data shows second-order kinetics:
· First 20 washes: 0.12-0.15% weekly decay
· 20-50 washes: 0.08-0.10% weekly decay
· Post 50 washes: <0.05% weekly decay
Q: Material durability differences?
A: Accelerated aging results:
· Cotton: ~14 month half-life
· Poly-cotton: ~22 month half-life
· Synthetic fiber: ~28 month half-life
· Specialty composite: ≥36 month half-life
Q: Humid environment impact?
A: Comparative studies indicate:
· 5°C temperature increase = 1.8× bacterial growth
· 10% humidity increase = 0.7% efficacy decrease
· Tropical conditions require 15-20% higher safety margins
