| Abstract: | In this study, a range of lightweight UV
protective layers has been developed from electrospun polyurethane loaded with
different amount of rutile TiO2 nanoparticles using electrospinning
with variable speed drum (collecting surface). To assess the degree of
protection of the manufactured layers, a braid from Zylon fibres has been
sheathed with the protective layers of different weight per braid unit length
and the strength of yarns raveled from the braids is measured. The strength
retention after exposure to artificial UV rays in Atlas Weatherometer for six
days is used as a measure of the degree of sheath protection. Electrospun
polyurethane layers loaded with 1% of TiO2 with weight of 2.29 g/m
braid, processed at high speed collector (87.7 m/min), provide the highest
protection among the developed electrospun polyurethane layers.
