Description

一种赛络菲尔复合纺纱的具有保温功能的纱线在线制备方法
技术领域
本发明涉及一种赛络菲尔复合纺纱的具有保温功能的纱线在线制备方法,属于纺织加工技术领域。
背景技术
赛络菲尔纺纺纱方法是在赛络纺基础上开发的一种新型纺纱方法。如中国公开出版物《西安工程科技学院学报》公开时间为2007年4月,文章名称为“棉/涤纶粘胶涤纶长丝Sirofil复合纱成纱工艺性能研究”,该技术的原理为粘胶涤纶长丝直接通过导丝装置从前罗拉喂入,并在前罗拉前钳口处与经过牵伸的棉棉粗纱须条保持一定的间距输出,经加捻三角区分别轻度初次加捻后在汇聚点处汇合,然后再次加强捻并合,继而被卷绕到纱管上形成赛络菲尔纱。因此,赛络菲尔复合纺纱方法具有长丝对短纤维良好的包缠特点,该纺纱方法能大幅度提高纱线强力和成纱质量。不足之处在于若想赋予纱线特殊的性能,则须在纱线后整理工序中添加改性工序。
常规提高织物保暖性的途径主要有:用传导系数较小的纤维材料制成保暖织物,纤维的导热性越小,其织物的保暖性越好;在纤维织物上施加具有远红外辐射特性的纳米材料,提高织物的保暖性;应用相转变材料,提高织物的保暖性。目前存在不少通过对织物涂层来制备隔热保温材料的方法,如中国公开出版物《现代纺织技术》公开时间为2017年12月,文章名称为“镁基涂层织物隔热效果影响研究”,该技术的原理为将氢氧化镁与水性聚氨酯树脂混合制成涂层胶,并对棉织物进行涂层整理来制备隔热保温织物。不足之处在于以上方法需要添加特殊装置来对织物涂层,延长了生产周期,使得生产环节复杂化,增加了生产成本。
发明内容
针对上述存在的问题,本发明的目的在于提供一种赛络菲尔复合纺纱的具有保温功能的纱线在线制备方法,为了实现上述目的,其技术解决方案为:
一种赛络菲尔复合纺纱的具有保温功能的纱线在线制备方法,该制备方法针对赛络菲尔复合纺纱,采用在环锭细纱机上涤纶长丝运行的途径中设置改性装置,改性装置由流量控制装置和润湿装置组成,在环锭细纱机上前罗拉至细纱管之间设置烘干装置,涤纶长丝经改性装置施加改性液后运行至前罗拉处,与经后罗拉、中罗拉牵伸后运行至前罗拉处的棉粗纱汇合,施加了改性液的涤纶长丝与棉粗纱在前罗拉的前钳口处加捻形成具有保温功能的细纱,该纱经烘干装置烘干卷绕到细纱管上。改性液由硅酸钙、PVA和蒸馏水调配而成,按质量百分比分别为:硅酸钙为3%~6%,PVA为7%~10%,蒸馏水为85%~88%。
由于采用以上技术方案,本发明利用赛络菲尔复合纺纱方法具有长丝对短纤维良好的包缠特点,在赛络菲尔复合纺纱过程中通过改性装置对涤纶长丝施加改性液后与棉粗纱加捻来得到具有保温功能的纱线。硅酸钙因其传导系数较低则可用来制作性能优异的保温材料,改性液由硅酸钙、PVA、蒸馏水组成,经改性处理后的纱线保温性能会随之增加。涤纶长丝经改性装置施加改性液后表面布满改性液,当涤纶长丝与棉粗纱在前钳口处因加捻作用而相互缠绕,涤纶长丝以空间螺旋状包缠在棉粗纱外侧,则从加捻三角区形成的细纱长度方向侧呈现一段涤纶长丝一段棉纤维的状态,涤纶长丝上的改性液向与其接触的棉纤维转移,由于涤纶长丝所带的改性液量有限,改性液不能完全将从加捻三角区形成的细纱长度方向侧呈现的棉纤维覆盖,所以细纱长度方向呈现一段改性一段不改性的状态。本发明制备的纱线中涤纶长丝经与棉纤维加捻缠绕后其表面仍保留一定改性液,棉纤维被涤纶长丝转移一定改性液后其表面也附着一定改性液,则经改性后的涤棉混纺纱与未经改性的嵌入式复合纺的涤棉混纺纱相比,其保温性能明显提高。
本发明设置的烘干装置进一步加快了蒸馏水的挥发速度,实现了纱线快速烘干的目的。细纱经烘干装置烘干后,纱线表面的蒸馏水挥发只留下粘合剂PVA和硅酸钙,则细纱以干燥的状态卷绕在细纱管上。本发明在嵌入式复合纺纱过程中对纱线进行改性,与常规在纺纱后对纱线改性的工艺相比,无需增加改性设备,实现了降低生产成本和减少生产周期的目的,且本发明制备的纱线与不经改性的赛络菲尔复合纺的涤棉混纺纱相比,纱线的保温性能得到明显提高。
