  3. Traditional Wound Care Products • Dressing sponges • X-ray detectable sponges • Laporatomy sponges • OR towel • IV sponges • General purpose sponges • Burn dressings

  4. Plain Gauze Sponge

  5. X-Ray Detectable Sponge

  6. Lap Sponge

  7. Lap Sponge

  8. OR Towel

  9. Nonwoven Sponge

  10. IV Drain Sponge

  11. Traditional Base Materials • Woven Gauze • Type VII USP gauze Structure • 32’s/19x9 • 40’s/20x12 • Others • Non USP gauze • 32’s/17x7 • Others • Synthetic Nonwovens • 70/30 Rayon/PET • 50/50 Rayon/PET

  12. USP Gauze Testing • Weight • Thread Count • Acidity • Surface-active substance • Starch and dextrin • Water-soluble substance • Ignite residue • Absorption capacity • Residue of ignition • Fluorescence

  13. Other Requirements for Base Materials • Appearance • Hand (feel) • Absorption • Capacity • Speed (sink time) • Debridement and wound treatment • Lint and loose thread • Tensile properties • Foreign particles • Bioburden level

  14. Applications • Woven Gauze • Dressing Sponge • General purpose sponge • Trach sponge • X-ray detectable sponge • Laporatomy sponge • OR Towel • IV sponge • Synthetic Nonwoven • Dressing Sponge • General purpose sponge • IV sponge

  15. Woven Gauze Characteristics • Favorable • Highly Absorbent • Good for debridement • Autoclavable • Predictable properties • Large volume of historical data • Unfavorable • Lint • Loose thread • Increasingly high cost

  16. Synthetic Nonwovens Characteristics • Favorable • Highly Absorbent • Economical • No lint • No loose thread • Unfavorable • Not suitable for wound debridement • Increasingly high cost of Rayon • Not autoclavable

  17. Ideal Base Material for Wound Care Products • Combining the favorable characteristics of cotton and nonwoven materials: • Absorbent • Natural cotton feel • Good for debridement • Autoclavable • Economical and stable pricing • No lint • No loose thread • Environmental friendly • Low bioburden level and Pyronema free

  18. Introducing PurCotton™ Nonwoven Cotton • Launched in 2006 by Winner Medical Group. • Proprietary and patented spunlace process. • Manufactured in ultra modern facility in Huanggang, China • Made with USA grown cotton.

  19. Capabilities of PurCotton™ Nonwovens • Basis Weight: 30 gsm to 120 gsm • Plain or Apertured • White or Colored • 100% Cotton or Cotton/PET Blend • Competitive pricing • Comparable to gauze products • More affordable than other cotton nonwovens

  20. Wound Care Applications for PurCotton™ • Plain Dressing Sponge • X-ray Detectable Sponge • IV Sponge • Dental Sponge • Laporatomy Sponge • OR Towel • Others

  21. PurCotton Dressing Sponge

  22. Aperture 1

  23. Aperture 2

  24. PurCotton X-ray Detectable Sponge

  25. PurCotton X-ray Sponge (Sterile)

  26. PurCotton Lap Sponge

  27. PurCotton OR Towel

  28. Cotton Nonwoven: OR Towel and Lap Sponge

  29. Physical Properties Summary for PurCotton™ • A wide range of properties • Basis weight • Absorption capacity • Tensile properties • Aperture • White or color

  30. Superior Characteristics of PurCotton™ over Gauze Sponge • Low Lint and no loose thread • Better for wound debridement • Very low bioburden level • Pyronema free • High bleaching temperature and long duration • USA grown cotton

  31. Nonwoven Cotton/PET Blend • Launched in 2007 • More economical than PurCotton (100% Cotton nonwoven) • Marketing need for an alternative to Rayon/PET blend: • Rapidly increasing prices for Rayon • More eco-friendly material

  32. Nonwoven Cotton/PET Blend • Cotton/PET Blend • 70/30 • 50/50 • Aperture • 24x20 • 20x10 • Typical Basis Weight • 30 gsm • 40 gsm • 50 gsm

  33. Superior Characteristics of Cotton/PET over Rayon/PET • More economical and longer term pricing stability • Autoclavable • Better hand feel • More favorable perception of Cotton by end-users • More eco-friendly than Rayon

  34. Wound Care Applications for Cotton/PET Blend • General Purpose Sponge • IV Sponge • Dental Sponge • Plain Dressing Sponge • Others

  35. Conclusions • Revolutionary spunlace nonwoven for making wound care products: • 100% Cotton Nonwovens (PurCotton™) • Cotton/PET Blends • PurCotton™ 100% Cotton Nonwoven • Ideal material combining best characteristics of cotton and nonwoven • Wide range of properties for making various wound care products • Nonwoven Cotton/PET Blend • Longer term pricing stability over Rayon/PET • Superior properties and more eco-friendly
