Abstract
The invention relates to fibers, particularly binder fibers, made from copolyesters and the copolyesters themselves. The copolyesters of the invention are generally formed from a glycol component containing 1,3- or 1,4-cyclohexanedimethanol and ethylene glycol and at least one dicarboxylic acid component. Such copolyesters may be formed into a variety of products, especially binder fibers for nonwoven fabrics, textile and industrial yarns, and composites.
