芳砜纶纤维发展概况及市场前景

芳砜纶纤维属于对位芳纶系列，是我国自行研究开发的芳香族聚酰胺类有机耐高温纤维，纤维强度为3．1～4．4cN／dtex、伸长率20％-25％、初始模量为7．45GPa、密度为1．416g／cm^3。由于具有各种优异的物化性能，芳砜纶纤维在国防军工和现代工业上有着重要的用途，是我国急需的高科技纤维品种。介绍芳砜纶纤维的物化性能、制造工艺、发展概况、应用领域及市场前景方面的一些情况，并对目前国内芳砜纶纤维的发展提出了一些建议。

Development survey and market prospect of polysulphonamide fiber

Polysulphonamide fiber belongs to para-position fragrant black silk ribbon series,it is the aromatic polysulphonamide organic thermostable fiber developed voluntarily by China, fiber stress is voluntarily 3.1 -4.4 cN/dtex, elongation ratio is 20% -25 % , initial modules is 7.45 GPa,density is 1. 416 g/cm^3. Because it has kinds of outstanding transformation performance,polysulphonamide fiber has play important role in national defense war industry and in modern industry, and is urgently needed in national high tech textile fiber variety. Polysulphonamide fiber transformation performance, fabrication technology, development survey, application domain, and market prospect aspect＇s some situation were introduced, and some proposals to the present Chinese fragrant polysulphonamide fiber＇s development were also put forward.
