Adhesion manner null of polyester type Kevlar and polyester type

摘要

PURPOSE: To improve the adhesiveness of polyester synthetic fibers to polyester elastomers by treating the fibers with a specific polyallylamine compound. ;CONSTITUTION: Polyester synthetic fibers are coated with a polyallylamine compound 2000-100000 in number-average molecular weight having a basic skeleton of the formula so as to be 0.01-5.0wt.% in the pickup of the compound, thus improving the adhesiveness between the fibers and polyester elastomers. Composite materials made up of the polyester fibers and such polyester elastomers are excellent in peel strength; therefore, being suitable for tarpaulins, canvas, etc., leading to recyclable, environmentally benign commodities.;COPYRIGHT: (C)1993,JPO&Japio
