Bioactive Composite Nonwoven Surgical Dressing based on Cellulose Coated with Nanofiber Membrane using the layer-by-layer technique

Nonwoven fabric with cellulosic base has many Features ability to absorb biological fluids and can easily adapt for different types locations of wounds, which made it common unique in surgical dressing. The study aimed To design samples one layer two layers nonwoven fabrics the inner deep endoscopic wound dressings control fluid leakage. 100% cotton, viscose, viscose/polyester (70:30) % were used as samples, every materials interchangeably two-layer (layer-by-layer) samples. One-layer dyed using green coffee extraction, while enhanced by adding powdered between them, an innovative use dressing applications. Electrospinning technique was form a delicate membrane Ciprofloxacin (CIP) antibiotic Kylie Collagen coat single-layer without dyeing compare their performance Also, comparing results that powder coating nanofibers membrane. Designed evaluated mechanical physical properties fabrics, addition, FTIR, SEM, absorbency antimicrobial activity, K/S especially finally cytotoxicity CIP, collagen, coffee. pointed one-layer extraction achieved high-performance function air permeability activity. While layer-by-layer showed improvement strength, properties, cotton/ viscose layers, viscose/ blended polyester followed sample coated 0.1wt% CIP
