Gauze Absorbency Analysis

Focus: Testing Dynamic Fluid Retention vs. Static Sinking Time.

This study examines how Oxygen-Bleached medical cotton outperforms traditional chlorine methods in capillary efficiency and clinical absorption capacity.

Metric Standard Gauze Kingphar Data
Sinking Time 4.5s - 5.0s < 3.2s
Absorbency Capacity ~5.0g/g > 8.2g/g
Capillary Rise (60s) 6.5mm 10.0mm

R&D Conclusion

The higher retention rate directly correlates to reduced tissue trauma during surgical dressing changes. Our proprietary vertical production ensures consistent pH levels (6.8-7.2) for optimal biocompatibility.

Expert Q&A: Medical Gauze Standards

Technical insights into manufacturing, compliance, and clinical application.

Is your gauze chlorine-free?
Yes. We use an advanced Oxygen Bleaching (Hydrogen Peroxide) process which is 100% Chlorine-free. This ensures no toxic residues and makes the gauze safer for sensitive wound care and surgical use.
How is X-ray detectability ensured?
Our X-ray detectable swabs feature a barium sulfate thread woven directly into the gauze. It contains over 55% barium sulfate, ensuring clear visibility under radioscopy during and after surgery.
What is your Sterility Assurance Level (SAL)?
We achieve a SAL of 10⁻⁶ through ETO (Ethylene Oxide) or Gamma sterilization. Every batch undergoes biological indicator testing to ensure absolute clinical safety.
Can you customize mesh sizes for tenders?
Absolutely. We produce standard meshes including 13, 17, and 20 threads per cm², and can adjust warp/weft counts to meet specific BP, EP, or USP compendial requirements for international tenders.
How do you prevent lint contamination?
All our gauze swabs are folded with "edges turned in" (American or French fold). This geometry hides raw edges within the pad, significantly reducing lint and loose fibers in the wound site.
Are your products EU MDR compliant?
Yes, Kingphar is fully certified under the latest EU MDR 2017/745 regulations. We provide full technical documentation (Annex II/III) and CE certification for Class I and Class IIa/b devices.
What is the pH value of your gauze?
According to EN 14079, we maintain a strictly controlled pH range between 5.5 and 8.0. Our rinsing process ensures zero fluorescence and minimal water-soluble substances.
Do you manage the full production chain?
Yes. We are vertically integrated—from spinning and weaving to bleaching and final sterile packaging. This allows us to guarantee consistent quality and price stability for large-scale hospital contracts.
