1、畢業(yè)論文題目涼爽纖維的制備與性能研究摘要:在炎熱的夏天,人們渴望船上有涼爽纖維面料做成的服裝,這種纖維的特點是能夠迅速吸收和傳輸人體皮膚表面的汗液,并帶走人體皮膚表面的熱量,使人體產(chǎn)生涼爽舒適的感覺。柔滑軟暖,清涼舒適,抑菌抗菌,綠色環(huán)保,天然保健的天然涼爽纖維——竹纖維必將成為涼爽纖維中的領(lǐng)頭軍。本課題以竹纖維為例講述了其制備過程及其紡紗工藝;通過具體實驗分析了竹纖維織物的導(dǎo)熱性及竹纖維的吸濕放濕性能關(guān)鍵詞:竹纖維導(dǎo)熱性吸濕性Abstract:Inhotsummer,peoplearelongingforacoolfabricmateria

7、希望衣服在夏天或炎熱潮濕的地方能起到降溫、排汗的功能。夏日既是陽光暴曬的日子,也是人們大汗淋漓的季節(jié),人們在防護自身免受紫外線侵襲的同時,又迫切需要穿著涼爽、舒適的服裝。這就對我們現(xiàn)有的傳統(tǒng)的紡織纖維提出了挑戰(zhàn),因此具有涼爽性的纖維材料受到了越來越多的人們的追捧。涼爽紡織品是未來消費市場的一大趨勢。1.1涼爽的定義涼爽的定義很廣泛對于涼爽纖維來講包括兩個方面:第一涼就是能起到降溫涼快的作用,這主要指纖維的導(dǎo)熱性;第二爽就是干爽,快速排汗,主要指纖維的去濕導(dǎo)濕性。由于汗在干燥時需要氣化熱,就抑制了體溫的上升,也就是說,由于人體所產(chǎn)生的汗能很快地
8、發(fā)散、氣化,與皮膚相接觸的布料部分是干爽的。這樣,穿著者就有清涼的感覺。1.2合成涼爽型纖維的研究現(xiàn)狀為了改善傳統(tǒng)棉纖維及織物的排汗快干性并配合與日俱增的化學(xué)纖維生
