REDUCED SOLIDITY WEB COMPRISING FIBER AND FIBER SPACER OR SEPARATION MEANS |
摘要 |
A web can comprise a substantially continuous fiber mass and a separation means dispersed into the fiber. The web having a preferred thickness resulting from forming a polymer material and a particulate into a fine fiber layer can have a variety of end uses. A filtration media can include a structure comprising such a web of fine fiber and a substantial volume of particulate embodiment of the separation means. The resulting fine fiber structure provides an improved filtration medium having substantial depth, thickness, and a layered structure. The improved properties of the web results from inclusion of the separation or spacer particulate.
