Development of Needle Punched Non-Woven Fabrics for Filtration Application

Abstract

Using bamboo cloth, polypropylene, cellulose acetate, and activated carbon, needle punching machines were used to create multi-layer nonwoven materials. Four distinct layers each include a varied ratio of textiles, including cellulose, bamboo cloth, and polypropylene. As the top, first middle, second middle, and bottom layers, respectively, acetate and activated carbon were utilized. Due to the density variation and shape factor of the fiber, the fabric's thickness and areal density varied depending on the proportion of each layer. The produced multi-layer nonwoven textiles' obtained filtration efficiency meets the theoretical solid volume fraction. The amount of activated carbon in the bottom layer results in less ion buildup in the water and improved filtration for particles smaller than 0.075 mm. percentage of bamboo fabric. The top layer results in less oil and gum in the water and improved filtering for particles smaller than 30 m. Different ratios of cellulose acetate and polypropylene fibers result in greater air permeability and filtration effectiveness. was greater than the top layer for particles 0.5–20 mm.
