摘要:
A papermaking fabric having a top layer and a bottom layer of interwoven machine direction (MD) yarns and cross-machine direction (CD) yarns bound together with warp binder yarns. At least some of the CD yarns are made of a material which generates a strong contractive force when returned to room temperature after heat-setting (annealing under MD tension). These CD yarns are positioned such that the strong contractive force offsets tension forces generated when the fabric is placed under load and which typically result in an edge curl. An exemplary material for these CD yarns is polybutylene terephthalate (PBT).
摘要:
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.
