Production of Porous Poly( p -dioxanone) Fibers during the Neck Propagation in Self-Excited Oscillation Mode

Features of the plastic deformation of poly( p -dioxanone) fibers in air were studied. The neck propagation in the deformation speed range 0.2–15 mm/min was shown to occur in the self-excited oscillation mode. It was detected for the first time that this process is accompanied by the formation of areas with an open-pore structure. Impregnation of the fibers with brilliant green with the penetration of the die from the solution into the pores produces fibers with antimicrobial properties against the fungal culture of Candida albicans .
