摘要: 利用电子显微镜和光学显微镜对鹅绒纤维和鸭绒纤维的形态结构进行观察,定量地阐述了鹅绒与鸭绒纤维在绒核结构、绒枝结构、绒小枝以及节点结构上的差异,并在这些形态结构差异的基础上对鹅绒纤维和鸭绒纤维的保暖性能进行测试,分析了结构差异对羽绒纤维保暖性能的影响。与鸭绒纤维相比,鹅绒纤维绒朵较大,绒核较小,绒枝长且粗,绒小枝较长且细,且分布较密,绒小枝上的节点小而多且分布均匀。这种形态结构使得鹅绒纤维能够保持更好的蓬松性,捕获更多的静止空气,具有更好的保暖性能。纤维体积分数和导热性能之间呈非线性关系,随着纤维体积分数的增加,纤维导热性先降低后升高,当纤维体积分数保持在0.002~0.005之间时,纤维的保暖性能最好。

Abstract: The morphological structure of duck down and goose down was observed using optical microscope and scanning electron microscope. Explained quantificationally every parts size of down stone, down branch, down fibril and the node structure. Besides, studied the thermal properties of different down fiber and discussed the effects of the structure differences on fibers thermal property. Compared with the duck down, goose down possesses bigger down cluster, less down stone, longer down branch and finer down fibrils. The down fibrils distribute denser and the nodes arrange evener than duck down. The morphological structure gives the goose down better bulkiness and better thermal properties. The thermal property nonlinearly depended on the fiber volume fractions. With the increasing of the volume fraction, the thermal property of the fiber decreases firstly, and them improves. By the test verified, when the volume fractions are between 0.002-0.005, the fiber possesses the best heat retention.
