Polyamide acids having flexible chains in the main chain were prepared by the condensation of 1,2-di(4-aminophenoxy)ethane,1,3-di(4-aminophenoxy)propane,1,4-di(4-aminophenoxy)butane and diphenylether 3,3′,4,4′-tetracarboxylic acid dianhydride,then coated the PAA on aramid fiber 1414 foundation fabric followed by a thermal imidization.

It introduces the application performance of aramid fibre which acts as the framework material of the conveyor belt,analyzes and researches the properties of Kevlar/nylon straight-longitude and straight-latitude composite canvas.

In this paper, the recipe of the adhesive system and dip coating technical of aramid fibre are studied.
