The main objective of this research is to synthesize silk fibroin fiber for indoor air particulate removal. Silk cocoons were degummed using 0.5 wt Na2CO3 alkaline solutions at 90 ÓìC for 60 mins, washed with distilled water, and dried at 80 ÓìC for 3 hrs in a vacuum oven. Two sets of experiment were conducted to investigate the impacts of initial particulate matter (PM) concentration and that of air flow rate on the removal efficiency. Rice bran collected from a local rice mill in Ubonratchathani province was used as indoor air contaminant in this work. The morphology and physical properties of silk fibroin (SF) fiber were measured. The SEM revealed the deposition of PM on the used fiber. The PM removal efficiencies of 72.29 ± 3.03 and 39.33 ± 1.99 were obtained of PM10 and PM2.5, respectively, when using the initial PM concentration at 0.040 mgm3 and 0.020 mgm3 of PM10 and PM2.5, respectively, with the air flow rate of 5 Lmin.
