Revise: Technical TextilesEnvironmentally friendly textiles include textiles used to prevent pollution, control erosion, clean air or water, and manage waste. A textile filter, for example, separates unwanted material from a flow of air or water. Its advantage is the reduction of contamination; a limitation is that the trapped material still needs appropriate handling or disposal.
