《GB/T 14338-2008化学纤维短纤维卷曲性能试验方法》由TC586（全国化学纤维标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准代替ＧＢ／Ｔ１４３３８―１９９３《合成短纤维卷曲性能试验方法》。本标准规定了化学纤维短纤维卷曲性能的试验方法。
本标准适用于聚酯（涤纶）、聚酰胺（锦纶）、聚丙烯腈（腈纶）、聚丙烯（丙纶）、聚乙烯醇缩甲醛（维纶）、纤维素纤维等化学纤维短纤维卷曲性能的测定。本标准与ＧＢ／Ｔ１４３３８―１９９３相比，主要变化如下：
―――增加了卷曲弹性仪技术要求（见５．１．１）；
―――增加了散件实验室样品的抽取和试验数量的确定（见６．１）；
―――增加了实验室样品的调湿时间（见６．２．１）；
―――修改了调湿和试验用标准大气的相对湿度（见６．２．２）；
―――增加了预加张力的求取方法（见６．２．４）；
―――增加了置信区间的半宽值（±３％）（见６．３）；
―――增加了快速调湿方法（见附录Ａ）。
