仿羽绒保暖材料的研究进展

Development progress of down-like thermal insulation materials

针对在仿羽绒纤维集合体开发中,纤维原材料的选用、纤维集合体成形加工技术等问题,通过查阅资料,了解仿羽绒保暖材料的开发进展,分析天然羽绒的形态结构特征及其保暖性能,重点对比仿羽绒纤维和仿羽绒纤维集合体材料的选用、加工方法,并总结出仿羽绒纤维集合体开发中应注意的问题。得出在仿羽绒纤维集合体加工过程中,要选择好粗细纤维的合理配比,做好纤维外观形态的改造,并对加工工艺参数进行优化配置,使制成的仿羽绒材料呈现球状或丛状纤维形态。

The morphological structure and thermal retention property of natural down were analyzed;the development progress of down-like thermal insulation material was reviewed. Especially the critical technology in the manufacture of down-like fiber and fiber assemblies were discussed, and the choice of fiber materials and the forming of fiber assemblies for the down-like fiber assemblies were analyzed. In the development of down-like fiber assemblies, the proper weight percentage of fibers with different diameters, the morphological modification of fiber surface and the optimal technology parameters are necessary, the final products should ideally be in the form of ball-shaped or cluster.
