Abstract
In this research, investigating the possibility of producing, fiber to fabric processing and also characterization of antibacterial organic/inorganic polypropylene (PP) filament yarns for permanent antimicrobial efficiency has been presented. The development of bacteriostatic filament yarn has been realized from mixing of virgin PP granule and various blending contents of silver/zinc-concentrated masterbatch. After producing as-spun filament yarns by a pilot plant melt spinning machine at the take-up speed of 2,000 m/ min, samples were drawn, textured and finally weft knitted. Physical and structural properties of as-spun and drawn yarns with constant and variable draw ratios were investigated and also tensile and crimp properties of textured yarns were evaluated. Tenacity and modulus of modified as-spun and drawn yarns were significantly higher than the pure PP. The investigation of antimicrobial activity showed a high percentage of biostatic efficiency on the modified samples.
