According to the World Health Organization there were an estimated 217 million cases of Malaria worldwide in the year 2017 with a co-occurrence of 435 000 deaths. As the Malaria incidence rate has plateaued for the past few years, there is a growing focus to provide outdoor protection in addition to indoor protection - specifically to the lower limbs. This is due to the preference of the main malaria vectors in Africa to feed close to the ground favoring the ankles and feet of victims. Protection by long lasting insecticide networks are not applicable outside and growing concerns of the impact of increased urbanization on waste management infrastructure in African countries and the lack of waste management infrastructure in rural areas, give rise to the feasibility and the need to investigate biodegradable alternative textiles. The objective of the present work was to investigate the influence of melt spinning processing parameters on the properties of biodegradable bicomponent poly(lactic acid) (PLA) filaments. This was achieved by using different grades of PLA that are commercially available and by utilizing the mosquito repellent DEET. Sheath-core structured filaments in the micro-range were produced with varying sheath-to-core ratios and DEET content. Special attention was given to the processing dependency of filament properties such as crystallinity, radial and surface morphology, sheath thickness and mechanical integrity. This presentation will highlight the influence of core to sheath ratio on fiber properties.
