多功能液芯熔纺长丝

Multifunctional liquid-core melt-spun filaments

为开发具有更高附加值的创新型纺织品,最有效的方式是在纤维水平上增强产品功能。双组分熔融纺工艺可赋予纤维多种功能。瑞士联邦材料科学与技术研究所开发的一类新型液芯长丝扩展了纤维的性能特征。由液体填充的聚烯烃和聚酰胺长丝的直径为45~200μm,其液体体积百分比高达25%。这是首次采用一步连续熔融纺丝工艺生产液芯纤维,有望提供有关阻尼、阻燃、添香及许多其他相关应用的潜在性能。

In order to develop innovative textiles of broader added value,product enhancements are most effective at the fiber level.With bicomponent meltspinning,several functionalities can be combined in one fiber.A new class of liquid-core filaments developed at Empa further expands the array of possible fiber performance characteristics.Liquid-filled polyolefin and polyamide filaments with diameters between 45 and 200μm and liquid volume perecntage up to 25% were produced.The authors believe that it is the first liquid-core fiber that is produced in a one-step continuous meltspinning process.It could be shown that the novel filaments provide promising propetries regarding damping,flame-retardancy,perfuming,and many other applications.
