The research and development of continuous basalt fiber /polyester woven filter cloth

Filter made by polyester woven fabric may deform in service, which may be improved by interweaving polyester and continuous basalt fiber filaments. The dimensional stabilities of polyester woven filter and continuous basalt fiber/polyester woven filter were observed under the conditions of dry heating at high temperature and hot dilute alkali environment. It was found that the continuous basalt fiber was helpful to improve the dimension stability of the woven filter fabrics in different concentrations of hot dilute alkali.
