         固体腈纶纱主要由聚并烯腈组成,它是用85以上的并烯腈和不超过15的二、三单体共聚而成,经湿法或干法纺丝制成短纤或长丝。并烯腈含量占85以上,称为一单体,纯净的聚并烯腈 结构紧密,性脆硬,染色性很差。二单体通常用含有酯基的化合物,如丙烯酸甲酯、甲基丙烯酸甲酯、醋酸乙烯酯等,二单体加入后,大分子排列的规整性变差,分子间作用力减弱,从而使纤维在微观结构上趋于疏松,纤维的柔软性提高,弹性和手感改变,并有利于染料分子的引入,改变纤维染色性。二单体含量约占5%-9%,其含量的多少除了影响纤维的染色性外,对其他性能也有显著影响。其他条件不变时,随着二单体含量的增加,由于丙烯酸甲酯的玻璃化温度降低,纤维的耐热变色稳定性下降,即受热后纤维易发黄,并使纤维的热蠕变量增加,热收缩变形性提高,初始模量降低,纤维受热后容易产生变形,但由于大分子链段的柔曲性提高,成品纤维表现出较好的弹性回复能力。加入第三单体,是为了向纤维中引入一定数量的亲热烈基团,以改变染色性能。第三单体含量很低,一般为1%左右。
