Tiivistelmä
Since insect-borne infectious diseases are responsible for a great number of deaths each year, it is essential to focus on developing methods to prevent them. Medicine has not provided a solution for this which is why manufacturing fabrics with anti-mosquito properties is essential.
The purpose of this thesis was to optimize anti-mosquito coating for cotton textiles. It was carried out using the sol-gel process. The work consisted of finding the best methods to fix sol-gel solutions and prepare films out of them. In addition, it was crucial to focus on retaining the physical properties of the textile substrate. This was examined with different characterization techniques.
The practical work of the project was performed in Universitat Politècnica de Catalunya in the Textile and Paper Department in Terrassa, Spain. This part of the thesis and all the results remain classified in order to respect the request from UPC.
One of the theoretical parts of the thesis focuses on understanding the coating and sol-gel process together with chemicals utilized in this work. The most important chemical was permethrin since it was the active principle. Various experimental procedures and techniques were used and it was necessary to study them first to comprehend them. The practical part describes all the processes and experiments which were performed during the project but they remain classified. The work itself consisted of mainly fixing sol-gel solutions and optimizing them based on the coatings results.
