Linen fabrics, one of the oldest natural cellulose fabrics, lack the functional properties for the medicalgarments that can be acquired using the green synthesis of silver nanoparticles. Therefore, the currentstudy presents a statistical design for one-pot green synthesis of silver nanoparticles (AgNPs) under UVlight using the natural polysaccharide (BSEPS) produced by Bacillus subtilis sp. suppress. The Taguchimethod was used to evaluate the optimal green synthesis of AgNPs, and obtain smaller nanoparticlessizes, by three effective factors, AgNO3 concentration, BSEPS concentration, and pH. In addition, thedeposition of AgNPs capped with BSEPS was investigated onto linen to promote antibacterial activity,functional surface properties, and dyeability. FTIR, XRD, TEM, SEM, and EDX have confirmed thefabrication and deposition of AgNPs on linen fabrics. BSEPS/AgNPs fabricating shows positive results forantibacterial activities against E. coli and S. aureus for linen fabrics, both undyed and dyed. The resultsrevealed that BSEPS/AgNPs played a dual role in reducing bacterial activity and increasing dyeability.
