天然纖維(wei)來源(yuan)(yuan)于(yu)有(you)機原(yuan)料，根據原(yuan)來的來源(yuan)(yuan)可以將天然纖維(wei)分為(wei)植物纖維(wei)（主要由(you)纖維(wei)素組(zu)成）和動物原(yuan)料纖維(wei)（主要由(you)蛋白質組(zu)成）。

自(zi)然(ran)界存(cun)在的(de)天然(ran)纖維(wei)(wei)主(zhu)要(yao)有，棉(mian)花，麻類，蠶絲和(he)(he)動物毛。其(qi)中棉(mian)花和(he)(he)麻類的(de)分(fen)子成(cheng)份主(zhu)要(yao)是纖維(wei)(wei)素，而蠶絲和(he)(he)毛類的(de)分(fen)子成(cheng)份主(zhu)要(yao)是蛋(dan)白(bai)質（呈聚酰(xian)胺高分(fen)子形式存(cun)在）。

天然界除棉花、麻類(lei)外，樹(shu)木(mu)、草(cao)類(lei)也大量生長著纖(xian)維素高分(fen)子(zi)，然而樹(shu)木(mu)、草(cao)類(lei)生長的纖(xian)維素，不是呈長纖(xian)維狀(zhuang)態存在，高樓逃生緩(huan)降(jiang)器，不能直接(jie)當(dang)作纖(xian)維來應用。
