Technical Q&A: Tropical Conditions Special Solutions
Q1: Does protective clothing fail during rainy seasons at 95% humidity?
A: Dragon Uniform humidity preconditioning test results:
Humidity Condition | Level B Protection Degradation | Level C Protection Degradation |
80%RH | ≤8% | ≤6% |
95%RH | ≤12% | ≤9% |
Q2: How to maintain protection after frequent washing?
A: Achieved through patented nano-encapsulation technology:
Wash Cycles | Flame Retardant Retention | Thermal Protection Degradation |
0 cycles | 100% | 0% |
30 cycles | ≥92% | ≤7% |
50 cycles | ≥85% | ≤15% |
Q3: Optimal multi-layer fabric combination?
A: Using thermal resistance synergy algorithm:
Rtotal1=∑i=1nRi1+αΔT
(α=Material coupling coefficient, ΔT=Temperature difference)
Actual measurement: Polyimide outer layer (R=0.18) + Aerogel lining (R=0.28) → Total thermal resistance 0.11m²K/W
