Fiber web size and production method and the usage where it confounds and the surface it connects

摘要

The absorptivity which includes the web size which the Kevlar confounds it is rinteingu fiber structure low, inside the top surface and the bottom surface at least the fiber of one side the surface it is connected by thermal or adhesive connection and the like. Web size, there being an absorptivity, is density low, there is rinteingu resistance, structural it is possible at high temperature just to maintain characteristic. The structure forms the web size of the Kevlar, makes the fiber of web size confound with needle processing or water-flow confounding processing, etc it is possible to make by connecting the fiber with the web size surface with thermal or adhesive connection.
