下面结合附图对发明作进一步详细的说明。
图 1示意性地显示了根据本发明的一种实施方式的新型复合弹性纱线。 如图 1所示， 该新型复合弹性纱线 1主要由两组纤维须条和一束芯丝 11捻合而成。 芯丝 11为一束复合弹性长丝。复合弹性长丝为弹性纤维长丝、低弹性或非弹性纤维长丝 的任意结合体。 复合弹性长丝优选为氨纶、 聚酰胺、 聚酯、 聚烯烃及其混合物、 变形聚合物 或共聚物。
纤维须条分为第一纤维须条 12和第二纤维须条 13。第一纤维须条 12与第二纤维须条 13 加捻成类股线状纱线体。
第一纤维须条 12与第二纤维须条 13围绕芯丝 11为中心构成新型复合弹性纱线。
芯丝 11的重量为纱线整体重量的 50%。 优选为芯丝 11的定量范围为 2CT400旦尼尔。 纱线定量范围由 Ne6至 Ne60之间， 优选范围在 Ne8至 Ne30之间。
本发明组成纤维须条的粗纱定量， 粗纱定量范围由 0. 2g/m至 1. 5g/m之间， 优选范围在 0. 4g/m至 1. Og/m之间。
纤维须条由纤维组成， 纤维为天然纤维、 合成纤维和人工染色纤维中的至少一种。 具体 来说， 就是纤维为天然纤维、 合成纤维、 人工染色纤维或它们的任意组合。
图 2示意性地显示了本发明一种制备上述新型复合弹性纱线的装置。
本发明制备新型复合弹性纱线的装置， 是在现有环锭纺装置的进行改造的， 主要改造包 括：
设置两个粗纱机构 2， 布置在后罗拉 3的上方， 用以装置两组纤维须条。
设置一个双眼导纱嘴 4， 布置在粗纱机构 2和后罗拉 3之间， 供两组纤维须条通过。 设置一个长丝退绕装置 5， 布置在后罗拉 3的上方， 用以装置芯丝 11。
设置一个导丝器 6， 布置在前罗拉 7的上方， 供芯丝 11通过。
其中， 双眼导纱嘴 4为可调式双眼导纱嘴， 两孔眼的调校范围为; Tl2mm。 长丝退绕装置 5为带张力控制的积极式长丝退绕装置。 导丝器 6为可调式导丝器， 导丝器 6的调校范围为 0〜15mm。
上述装置的工作原理如下：
首先， 将两组纤维须条粗纱卷装安装到粗纱机构 2上。将芯丝 11卷装安装到长丝退绕装 置 5上， 然后启动机器。 两组纤维须条经双眼导纱嘴 4喂入后罗拉 3， 经过后罗拉 3和中罗 拉 8、 前罗拉 7的适当牵伸， 从前罗拉 7的钳口输出。 透过调校导丝器 6， 使芯丝 11独立地 被调整到所属两组纤维须条中间位置： 当第一纤维须条 12、 第二纤维须条 13从前罗拉 7钳 口输出时， 先进行初捻， 再围绕芯丝加捻形成类似股线的新型复合弹性纱线。
通过调校双眼导纱嘴 4两孔眼之间的位置， 除确保两组纤维须条能平行地喂入装置的同 一牵伸区中进行牵伸外， 亦同时控制两组纤维须条之中心距离保持在 3mm至 12mm之间。 本发明的纱线主要通过在纺纱三角区单股纤维须条先进行初捻， 形成单股纱线体， 然后 再与芯丝 11进行第二次加捻。 由于纤维须条在主加捻点前已变成圆柱型纱线体， 有利于纤维 端缠入纱线体内，而且处于中间位置的芯丝 11呈螺丝状地与其两组纤维须条单股纱线体互相 包缠，再加上芯丝 11对两组纤维须条产生一定的握持效应，使纤维不易脱落，纤维利用率高， 因此成纱不仅毛羽少、 强力亦高。
本发明的新型复合弹性纱线， 适合各类纺织织物或成为各类纺织织物的组成部份， 因此 根据本发明的一些实施方式， 新型复合弹性纱线可优选被纺织成粗斜纹布织物 (Denim)。而其 在纺织织物中所占组成部份的多少， 对能成功实践本发明并不重要， 一般范围至少占 15%， 而优选范围在至少占 20%。
