Abstract
The invention is yarn, fiber, film or tape composed of a compatibilized blend of polyester and polyamide resins, with improved fibrillation and abrasion resistance, and an industrial fabric produced thereof. The blend uses carbodiimide (CDI) compound containing at least two carbodiimide groups in the molecule as a compatibilizing agent. A unique, high modulus, dimensionally stable and abrasion resistant yarn, fiber, film or tape is created as a result of the combination of the polyester and polyamide with CDI in a preferred proportion.
