1、毕业论文题目凉爽纤维的制备与性能研究摘要：在炎热的夏天，人们渴望船上有凉爽纤维面料做成的服装，这种纤维的特点是能够迅速吸收和传输人体皮肤表面的汗液，并带走人体皮肤表面的热量，使人体产生凉爽舒适的感觉。柔滑软暖，清凉舒适，抑菌抗菌，绿色环保，天然保健的天然凉爽纤维——竹纤维必将成为凉爽纤维中的领头军。本课题以竹纤维为例讲述了其制备过程及其纺纱工艺；通过具体实验分析了竹纤维织物的导热性及竹纤维的吸湿放湿性能关键词：竹纤维导热性吸湿性Abstract：Inhotsummer,peoplearelongingforacoolfabricmateria

7、希望衣服在夏天或炎热潮湿的地方能起到降温、排汗的功能。夏日既是阳光暴晒的日子,也是人们大汗淋漓的季节,人们在防护自身免受紫外线侵袭的同时,又迫切需要穿着凉爽、舒适的服装。这就对我们现有的传统的纺织纤维提出了挑战,因此具有凉爽性的纤维材料受到了越来越多的人们的追捧。凉爽纺织品是未来消费市场的一大趋势。1.1凉爽的定义凉爽的定义很广泛对于凉爽纤维来讲包括两个方面:第一凉就是能起到降温凉快的作用，这主要指纤维的导热性;第二爽就是干爽，快速排汗，主要指纤维的去湿导湿性。由于汗在干燥时需要气化热，就抑制了体温的上升，也就是说，由于人体所产生的汗能很快地

8、发散、气化，与皮肤相接触的布料部分是干爽的。这样，穿着者就有清凉的感觉。1.2合成凉爽型纤维的研究现状为了改善传统棉纤维及织物的排汗快干性并配合与日俱增的化学纤维生
