摘　　要：聚氨酯是一类弹性共聚物,以伸长率高和弹性非常好而著称。聚氨酯聚合物可具有不同的硬度等级,这使其应用范围广泛,如包装、密封、涂层及纺织品等。伸长率和弹性被认为是纺织品的重要性能,因为这些性能在纺织品的穿着舒适性和形状保持性方面起着重要作用。据研究,80%的服装含有不同比例的弹性长丝。这表明服装工业中不可避免地会使用弹性长丝。概述了聚氨酯的性能、长丝生产工艺及其熔融纺丝工艺的最新进展。Polyurethanes are a class of elastic copolymers,which are known for their high elongation and very good elastic properties.Polyurethanes as polymer are available in variable hardness grades,which make them suitable for a long range of applications i.e.packaging,sealing,coating,textile applications etc.Elongation and elasticity are regarded as important properties of textiles as these properties play an important role in the wear comfort and shape retention of the textiles.According to a study,80%of clothing contains elastic filaments in variable proportion.This makes the use of elastic filaments unavoidable in the apparel industry.This article gives an overview of polyurethane properties,filament production processes and recent advancements in the melt spinning process.
