Why does purity matter in surgical and absorbent cotton? Here is a breakdown of clinical cotton testing standards.
Surgical absorbent cotton is a fundamental medical consumable used in clinics, hospitals, and surgeries worldwide. But what makes medical-grade cotton different from cosmetic or standard commercial cotton?
First and foremost is the bleaching process. Standard cotton contains natural waxes, fats, and impurities that prevent absorption. Surgical cotton undergoes a specialized cleaning, boiling, and bleaching process to remove these substances, making it highly hydrophilic (absorbent).
Key parameters for clinical cotton include:
1. Absorbency Rate: The cotton must sink and absorb water in under 10 seconds.
2. Water-holding Capacity: It must hold at least 23 times its own weight in water.
3. Acidity/Alkalinity: It must be neutral to prevent skin irritation or wound infections.
4. Optical Brighteners: Standard cotton uses chemical optical brighteners to look white, but surgical grade cotton restricts this to avoid tissue reaction.
At Ashirvada Industries, our ASHICOT line is rigorously tested under ISO 13485 guidelines to ensure every roll meets these medical standards.
