    摘要: The properties of nonwoven glass fiber and nonwoven polymer fiber are combined efficaciously in a composite web that comprises two component webs of particular composition. One of the component webs is formed by screen casting, squeezing, and drying an aqueous dispersion of glass fiber, thermoplastic fiber, and a hydrophilic polymer so that temporary adhesion bonding occurs. The other of the component webs is formed by orienting textile polymer fiber and thermoplastic fiber so that temporary matting occurs. The composite web is formed by superposing and calendering the component webs under heat and pressure so that fusion bonding of the thermoplastic fiber occurs within each and between both of the component webs. As a result, the glass fiber and textile fiber are predeterminedly locked and the properties of both are predeterminedly available.
