为了探明不同环境湿度和外加压力作用后木棉纤维的中空压缩状态,采用KES(Kawabata Evaluation Systems)压缩仪分析测试干处理和湿处理以及外力联合作用后木棉纤维集合体的压缩性能.结果表明:干燥木棉纤维集合体的压缩弹性优于潮湿木棉纤维集合体；经外力作用后干燥和潮湿木棉纤维集合体蓬松度均有所下降,但干燥木棉纤维集合体的内部空隙和纤维圆中空结构的损失要小于潮湿木棉纤维集合体.压缩性能试验可用于间接评价木棉产品中木棉纤维的中空状态及制造技术.%Intending to find out the compression status of the hollow structure of kapok fibers under different humidity and pressure treatment, the compressibility of kapok fibrous assemblies was analyzed under dry, wet and pressure combined treatments by KES (Kawabata Evaluation Systems)compression testing machine. The results showed that the compression elasticity of dry kapok fibrous assemblies was better than that of wet kapok fibrous assemblies; the bulkiness of dry and wet kapok fibrous assemblies both reduced when they were pressed, however, the pore among wet kapok fibrous assemblies and their hollow structure were easier to decrease than dry kapok fibrous assemblies when they were pressed. The compression test is probably to be an indirect evaluating method of kapok fiber hollowness and manufacturing technology of kapok products.
