Fibre Chemistry Aims and scope

Abstract

The characteristics of modification of PET with aqueous solutions of equimolar amounts of ammonium nitrate and sodium hydroxide are investigated. It is shown that such treatment of the polymer is not equivalent to treatment with weak aqueous solutions of ammonia. It removes a significant amount of oligomers contained in the polyester but does not cause their intensive decomposition. It was found that this modification can increase the dyeability of polyester material and decrease the electrical resistance by 10–100 times in the most severe conditions.
