CHEMISORPtION OF SULFUR (IV) OXIDeBY PoLYETHYLENEPOLYAMINE IMPREGNATED FIBROUS MATERIALS. 1. HYDROPHILIC POLYETHYLENEPOLYAMINE IMPREGNATED FIBROUS MATERIALS

Abstract

The hydrophilicity of artificial and synthetic fibers and polyethylenepolyamine (PEPA) impregnated fibrous materials based on them was investigated under static conditions using a vacuum sorption installation. Water vapor sorption isotherms were analyzed and monolayer capacitance values and a water molecules adsorption in the first layer heats were determined in the framework of polymolecular adsorption Brunauer – Emmett – Teller. It has been found that the hydrophilicity of the fibers studied to change in the following sequence: viscose > VION AN-3 > VION KN-1 > nylon-polyester > nitrone > polyester > polypropylene; PEPA modified hydrophilic fibrous material does not depend essentially on the chemical nature of the carrier.
