Natural colorants have emanated as a significant substitute to highly toxic synthetic dyes. The present study highlights the dyeing efficiency of violet pigment produced from Chromobacterium violaceum PDF23. A halophilic bacterium C. violaceum PDF23 produce violet pigments were isolated from the Great Salt Lake situated in Chennai, India. Based on morphology and 16S rRNA gene sequencing, a halophilic bacterium was identified as C. violaceum PDF23. The violet dye from C. violaceum PDF23 exhibited antimicrobial efficacy against S. aureus, B. subtilis, E. coli, P. aeruginosa, and C. albicans. The violet pigment exhibited radical scavenging potential with IC50 value of 14.40 μg/mL. The dye ability of colorant was evaluated using mordants on two distinct fabrics, i.e., silk satin and cotton, and colorfastness measurements were recorded. The CIE L ∗ a ∗ b ∗ qualities of the dyed fabrics were assessed, as well as their colorfastness quality. The current research findings suggest that violet pigment has potent antimicrobial and antioxidant activity and it could be used as alternative to synthetic dye in the textile industry.

“…Alum is a traditional natural inorganic mordant that is hydrated with double sulfate salts. It is often called the hydrated aluminum potassium sulfate (KAl (SO 4 ) 2 .12 H 2 O) [35][36][37]. So, the dyeing in presence of Alum fixes the components extracted from green coffee on the fabric at the dyeing bath.…”

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