MEASURE THE ULTRAVIOLET PROTECTION FACTOR (UPF) OF FABRICS ON UV-VIS SPECTROPHOTOMETER

Tóm tắt

Ultraviolet Protection Factor has been interested in the textile industry in the field of protective clothing, but measuring devices are quite rare and expensive compared to their effectiveness, so they are not easily found in textile material laboratories in our country. The UV-VIS spectrophotometer is equipped in biochemical or food laboratories and is commonly used to determine the concentration of solutions or chemical groups present in the solution, and the machine is not used to measure solid materials. This study introduces a method to measure the penetration (transmission) of fabrics in the ultraviolet radiation region and builds software to automatically calculate the UPF from the results received on the UV-VIS spectrophotometer at the Center of Experiment and Practice of our HUFI University
