    Novel approach for the production of poly (vinyl alcohol) nanofibers: Centrifugal spinning
    (Chamber of Textile Engineers, 2018) Akgül, Y.; Kiliç, A.
    One of the emerging technologies for the nanofiber production is "centrifugal spinning". It is a compatible technique for industrial applications due to higher production rates compared to electrospinning, which is the most widely used method. In this study, poly(vinyl alcohol) nanofibers which are used in high value added products such as biomedical applications and lithium ion battery electrodes were produced via centrifugal spinning. Effect of production parameters (solution concentration, needle diameter, rotor speed and needle-collector distance) on fiber morphology was investigated with SEM images. Optimum conditions were determined as 10-15 wt% solution concentration, 6000-9000 rpm speed, 0.5 mm needle diameter and around 150 mm needle-collector distance. Also, nanofibers with diameters below 200 nm were produced at industrial rates. © 2012 Journal of Textiles and Engineer.

    Production of nanofibrous wound dressings via solution blowing
    (Chamber of Textile Engineers, 2018) Canbay, Gökçe, E.; Akgül, Y.; Kiliç, A.; Açma, E.
    In this study, thermoplastic polyurethane (TPU) nanofibers were produced via a novel technique: solution blowing. Smoke tree oil was obtained with soxhlet extraction and according to GC-MS analysis; it was shown that obtained extract includes constituents with high antimicrobial activity. Therefore, TPU nanofibers coated with smoke tree oil at different amounts using drop casting in order to obtain antibacterial nanofibers. All coated nanofibers showed antibacterial activity against to S.Aureus and E.Coli. On the other hand, SEM images show that increase of amount of smoke tree oil effect to fiber morphology negatively. Thus, air permeability of nanofibers mats decreased significantly. © 2012.
