Description
技术领域
本发明属于混纺纱线领域，具体涉及一种热湿舒适性的超仿棉聚酯纤维混纺纱线。
背景技术
随着科技的不断进步以及人们生活水平的不断提高，人们对穿着的舒适性要求越来越高。特别是在特殊工作环境和特殊领域里，如高温、高湿作业的工作人员、高竞技运动的运动员、部队官兵、公安干警、武警官兵对内衣、夏装和工装等的热湿舒适性有更强烈的要求。因为在高温、高湿的环境状态下，人体与衣服之间的摩擦力会明显增大，沉重感明显增加，此时就要求织物具有更好的热湿舒适性。
众所周知，涤纶是合成纤维的第一大品种，2012年中国的涤纶产量为3057万吨，占到化纤产量的80.6%，因其优良的物理和化学特性而被广泛应用于服装面料以及其他非服装领域。涤纶产品自问世以来，曾以其悬垂性好、强度高、优良的抗皱性及洗可穿性能而被广泛应用于服用纺织品，但由于它的疏水特性导致吸湿性差、易产生静电，而在对吸湿性要求较高的领域中的应用受到了限制。为满足市场需要，各种具有优良性能的改性涤纶品种不断被推出，其中具有穿着舒适性的改性涤纶的研究近年来有很大进展。改性的方法主要通过化学改性和物理改性方法。
粘胶纤维具有自然降解、环保可再生、特殊外观风格、舒适性与价格低等优点，但其湿强度低、织物形态不稳定特别是功能单一特点在很大程度上限制了粘胶纤维的大量应用。如利用同是再生纤维素纤维的莱赛尔（Lyocell）纤维取代部分粘胶纤维，将在新开发织物外观风格和手感、服用舒适性与功能性方面有所突破。
发明内容
本发明的目的在于针对现有织物无法达到高湿高热条件下的舒适性，提供一种热湿舒适性的超仿棉聚酯纤维混纺纱线。该混纺纱线其强力、舒适性、透气性、色牢度均超过国家标准要求，是一种化解我国目前聚酯纤维产能过剩，替代棉纤维织物的新型混纺纱线。
为实现上述目的，本发明采用如下技术方案：
一种热湿舒适性的超仿棉聚酯纤维混纺纱线，按质量分数计，其原料组成为：超仿棉聚酯纤维30-50%、莱赛尔纤维25-35%、粘胶纤维25-35%，以上各原料质量百分数之和为100%。
所述的热湿舒适性的超仿棉聚酯纤维为亲水易染型超仿棉聚酯纤维或微孔超仿棉聚酯纤维。
所述的热湿舒适性的超仿棉聚酯纤维混纺纱线，按质量分数计，其原料组成为：亲水易染型超仿棉聚酯纤维40%、莱赛尔纤维30%、粘胶纤维30%。
所述的热湿舒适性的超仿棉聚酯纤维混纺纱线，按质量分数计，其原料组成为：微孔超仿棉聚酯纤维50%、莱赛尔纤维25%、粘胶纤维25%。
微孔超仿棉聚酯纤维的制备方法为：室温下，将微孔型聚酯纤维按浴比1:20放入纤维开孔液中，升温至100～135℃，保温20～60 min，然后用95℃水漂洗2次，25℃水漂洗2次，制得微孔超仿棉聚酯纤维；所述的纤维开孔液中氢氧化钠的含量为5-15g/L，碱减量促进剂 TF-118L的含量为0.1-0.5g/L；微孔型聚酯纤维的减量率控制在5-15%。
不同减量率对纤维强度有影响，从而以不同减量率的纤维制成的纯纺织物吸湿快干性能、抗起毛起球性能也不同。
所述的热湿舒适性的超仿棉聚酯纤维混纺纱线的制备方法，包括以下步骤：
（1）开清棉：操作过程中控制棉箱的储棉高度为3/5；
（2）梳棉：生条干定量20g/5m，刺辊转速800 r/min，道夫转速18 r/min，锡林转速300 r/min，锡林~盖板隔距0.29mm、0.25mm、0.25mm、0.25mm、0.29mm，锡林~刺辊隔距0.13mm，锡林~道夫隔距0.10mm，刺辊~分梳板间的隔距1.2mm；
（3）细纱：粗纱定量4.2克/10米，罗拉隔距16.5 mm×40 mm，罗拉加压135N×100N×135N，后区牵伸1.16倍，锭速15600 r/min，钢领型号PG14254，钢丝圈型号bracker4/0。
亲水易染型超仿棉聚酯纤维混纺纱线的制备工艺为：原料检验→JWF1012往复式抓棉机→JWF1024多仓混棉机→JWF1126开棉机→JWF1204A梳棉机→HSD961一并→HSD961二并→DV2-AL末并→FA467E粗纱机→DTM1129细纱机→POLAR E自动络筒机；
微孔超仿棉聚酯纤维混纺纱线的制备工艺为：原料检验→微孔超仿棉开孔处理（碱减量开孔）→JWF1012往复式抓棉机→JWF1024多仓混棉机→JWF1126开棉机→JWF1204A梳棉机→HSD961一并→HSD961二并→DV2-AL末并→FA467E粗纱机→DTM1129细纱机→POLAR E自动络筒机。
本发明的有益效果在于：
1）本发明以超仿棉聚酯纤维为主要原料，以莱赛尔纤维取代部分粘胶纤维，科学精确配比，制得强力、舒适性、透气性、色牢度均超过国家标准要求的混纺纱线，有效地化解了我国目前聚酯纤维产能过剩的问题；
2）本发明的制备工艺简单，易于推广实施，所仿制的纱线各项技术指标均特别适合于用于纺织高热湿舒服的面料。
