摘要：

测试并分析一种新型超细旦异形腈纶纤维的表面形貌、化学成分、超分子结构、热稳定性能、回潮率和保温性能，研究氢氧化钠，浓硫酸，一般有机溶剂、双氧水和保险粉对其白度与力学性能等的影响。结果表明：该纤维截面呈哑铃型，表面致密，保持了普通腈纶的优良性能，具有稳定的热性能，且耐酸性，耐碱性较好，耐一般有机溶剂性好，耐氧化还原性好；回潮率和保温性能均优于普通腈纶纤维，纤维具有普通腈纶的特征基团，可用阳离子染料染色。

Abstract:

The surface morphology, chemical composition, supra-molecular structure, thermal stability and moisture regain and thermal property of a new fine-denier profiled acrylic fiber are investigated. Meanwhile, the influence of sodium hydroxide, concentrated sulfuric acid, organic solvent and hydrogen peroxide, sodium hydrosulfite on the whiteness and mechanical properties of fiber is researched. The results show that the cross-section of this new fiber is dumb-bell-shaped and the surface is smooth in longitudinal fibril structure without any grooves. The fine properties of ordinary acrylic such as stable thermal performance are maintained. Meanwhile it is resistant to acid, alkali, ordinary organic solvents, and some reducing agent and oxidants. Other performance such as moisture regain and insulation performance are superior to these of ordinary acrylic. It has characteristic functional groups of ordinary acrylic, so it can be dyed by cationic dyes.

Key words: fine-denier profiled fiber, ordinary acrylic, structure, physical and chemical property
