Abstract
Polybutylene (PB-1) fibers were spun at spinning speeds of 250–2500 m/min. A tensile tester was used to analyze the stress-strain behavior of these fibers. In addition, birefringence and the effect of aging were examined. A DMA (dynamic mechanical analyzer) was used to measure the storage modulus and loss modulus of the fibers. Nonwoven mats of the fibers were prepared and compression tests were run on these mats. The properties of the polybutylene fibers and mats were compared with the properties of common polypropylene fibers and mats.
