熔纺氨纶混纺针织物的防脱散性能分析

Research on Ladder Proof Performance of Melt Spinning Spandex Blended Knitted Fabric

熔纺氨纶具有熔点低、黏性高的特点,因此,在一定条件下,熔纺氨纶能与其他纤维黏连,形成具有良好防脱散性能的熔纺氨纶织物。实验通过分析熔纺氨纶分别与棉、生丝和锦纶在不同热定型条件下的黏结情况及热定型条件对黏结性的影响,确定熔纺氨纶和热塑性纤维具有良好的黏结效果;通过研究最佳黏结的熔纺氨纶-锦纶针织物在不同热定型条件下的防脱散性能,为防脱散针织物开发提供参考。

Melt spinning spandex is characterized by low melting point and high viscosity. Therefore, melt spinning spandex can cohere with other fibers under certain conditions, thus forming melt spinning spandex fabrics with good ladder proof performance. The experiment determines that melt spinning spandex and thermoplastic fiber have good viscosity by analyzing the coherence of melt spinning spandex respectively with cotton, raw silk and chinlon under different conditions of heat setting and the influence of heat setting conditions on viscosity, and provides reference for the development of ladder proof knitted fabrics by studying ladder proof performance of melt spinning spandex-chinlon knitted fabrics with optimal viscosity under different heat setting conditions.
