Procedure to treat Adhesive activated Polyester material with chemically stabilized Polyester material treated by the procedure and an improved Composition of finished

摘要

The present Invention relates to process for treating Polyester material chemically stabilized, activated AdhesiveCharacterized in that it comprises: (a) put him chemically stabilized Polyester material with a composition comprising: (i) about 1 to about 50 percent in PESo is a Dry epoxy Compound having a Plurality of Group 1,2 - and an epoxy equivalent Weight of less than about 500 per Group(ii) a compound capable of releasing at least approximately 0.004 equivalent epoxy equivalent of a catalyst is one of the ions selected from the group consisting of Potassium Ammonium Rubido, cesium, and mixtures thereof,Where the composition is regulated to obtain a pH within the range of approximately 7.5 to approximately 13.0; and (b) stretch Polyester material, where the material is stretched Polyester carboxyl end group level of less than about 18 microequivalentes per gram.
