How to distinguish between PROTECTIVE GOWNS and SURGICAL GOWNS?
I. Basic Definitions & Core
Differences
Protective Gowns
• Nature: Full-body sealed PPE,
composed of PP non-woven fabric laminated with breathable membrane
• Core Function: Blocks blood,
body fluids, aerosols, and biohazards (e.g., Ebola, COVID-19)
• Key Metric: Liquid penetration
resistance ≥1.67 kPa (Level 3 standard)
Surgical Gowns
• Nature: Sterile/clean surgical
barrier, typically SMMS non-woven fabric (Spunbond-Meltblown-Meltblown-Spunbond
composite)
• Core Function: Prevents
microbial shedding from skin and bidirectional contamination in surgical fields
• Key Metric: Microbial barrier
rate ≥70% in wet state (Level 3 surgical gown)
