Abstract
Regenerated silk fibers were fabricated through dry/wet spinning process, N-methyl morpholine- N-oxide (NMMO) solvent and methanol coagulant. Several concentrations of polyhexamethylene biguanide (0.5, 0.75 and 1% (v/v)) and silver nanoparticles (5, 15, 55, 95 and 135 ppm) were used separately and mixed as the antibacterial agent for producing antibacterial fibers from dipping process and also antibacterial property against the gram-positive bacterium: Staphylococcus aurous was investigated. The results showed that; high concentrations of silver nanoparticles in the fibers had more inhibitory effect, but these high concentrations were caused to change the color of goods. Also in the case of polyhexamethylene biguanide; the inhibitory effect of fibers were improved with increasing the concentrations of them. Compositions of these two antimicrobial agent determined that maximum inhibitory effect in this situation can be achieved in smaller amounts of that. As concentrations of 55 ppm AgNPs and 0.75% (v/v) of PHMB were demonstrated the maximum inhibitory effect with the least amount of discoloration in fibers.
