摘　　要：研究羊毛、山羊绒、腈纶、鹅绒、木棉5种纤维集合体的压缩性能。通过单向施力挤压,对纤维集合体的压缩特征曲线进行表征,同时完成特征值的提取。发现5种纤维集合体的压缩曲线、压缩应力与应变曲线、压缩模量曲线存在明显差异,这主要与纤维的形态及结构有关,并将压缩过程分为3个区:近似线性区、转变区(或滑移变形区)、模量线性增加区。The compressional acrylic, goose down and kapok. behavior of five fiber assemblies was investigated, i.e. wool, cashmere, Through one-way compressing the fibers, the compression characteristic curves were characterized and the eigenvalues were extracted. There were evident differences for the compressive curves, compressing stress and strain curves, modulus curves of five fiber assemblies. This is attributed to the fiber morphological structures. The compression process could be divided into three areas： linear area, transition area （or slipping area） and linear strengthening area for modulus.
