纺织品用阻燃聚酰胺

Flame-retardant polyamides for textile applications

德国纺织与纤维研究所(DITF)开发的阻燃聚酰胺纤维被广泛用于制备各种纺织品。除实现了聚酰胺6(PA 6)高持久阻燃效果的主要目标外,由这种纤维制得的纺织品还表现出非常好的材料特性。它们对不同种类的染料均具有良好的上染性,其耐磨损和耐摩擦牢度高,证明了阻燃成分对阻燃聚酰胺纤维制品的性能不产生影响。此外,阻燃成分与聚合物分子链的结合可防止其迁移至纤维表面,这一点可通过纺织品皮肤相容性测试进行验证。进一步研究有关变形阻燃纺织品的生产及对普通纱线纺织品的燃烧性能变化进行测试将是当前研究的主题。

The intrinsically flame-retardant polyamide fibers developed by DITF are suitable for a wide range of textile applications.In addition to the primary objective of achieving a high and permanent flame-retardant effect for polyamide 6(PA 6),the textiles obtained from these fiber show very good material properties.Good dyeability with different dye classes combined with a high dye absorption as well as high abrasion resistance and rub fastness proves that the flame-retardant components do not influence the material properties.In addition,their incorporation into the polymer chain prevents them from migrating to the fiber surface,which has been clearly demonstrated by skin compatibility tests.Further investigations with regard to the production of a textured flame-retardant textile and the determination of the changed fire behavior in relation to the textile made of plain yarn are the subject of current research.
