Properties of textile air conditioner waste dust-filled polyurethane rigid foam composites

This paper investigates the morphology, mechanical and thermal insulation properties of textile air conditioner dust-filled polyurethane (PU) rigid foams. Textile air conditioner dust occurs during the spinning process of staple fibres. It consists of cotton fibre impurities as boll, leaf, and short fibres that generate a vast environmental load. This dust is used as a filler and dispersed in polyurethane up to 40% wt. The cell -size of foams...
