Description
技术领域
本发明涉及弹性面料染整技术领域,具体涉及一种涤棉混纺纬向双包弹力面料的制备方法。
背景技术
面料的高弹性指标提升与拒水拒油整理的融合,是指染色织物在使用或加工过程中,经受外部因素(挤压、摩擦、弯曲、水洗等)作用下的弹性持久性和良好回复性,是织物的一项重要物理指标。为提高弹性拉伸弹力,在原有T400纬弹的基础上,采用纤维双包的方式,用T65%/C35%的纬纱将高机械弹力T400与氨纶缠绕合捻包覆,这样做的优点,保证了良好的弹性回复率,降低了弹性增长率,从而避免了面料在长期穿着使用中造成的鼓包起泡、变形的问题,产品反复穿着之后伸缩自如,在膝盖、肘部的部位快速恢复,挺括有型,抗皱耐穿。上述面料在染整加工中进行必要的三防整理时,三防整理的高温焙烘会影响面料的弹力,使制备的面料成品弹力下降,影响弹力面料的性能。
发明内容
针对现有技术制备涤棉混纺纬向双包弹力面料弹性性能差的技术问题,本发明提供一种涤棉混纺纬向双包弹力面料的制备方法,权衡氨纶弹力与三防后焙烘温度的关系,既保证了弹性,同时具备防水、防油、防皱的三防防护功能,所制备的面料适用于工装租赁、训练服装或工装穿着。
本发明提供一种涤棉混纺纬向双包弹力面料的制备方法,包括如下步骤:
(1)退煮漂联合处理:
退浆机前段工作液:烧碱28-30克/升,退浆精炼剂6-8克/升,分散螯合剂2克/升,渗透剂2-3克/升;处理工艺为:履带箱温度101-102℃,堆置时间45min;
退浆机后段加料氧漂用料:双氧水7-8g/L,工作液pH值10-11,精炼剂2g/L,稳定剂10-12g/L,水玻璃6g/L,分散螯合剂2g/L;履带箱温度95-100℃,堆置时间40min;
(2)定型工艺:温度:195℃,车速:50米/分,超喂:10%,风量:50Hz,幅宽:平进平出;
(3)丝光工艺:车速70m/min,水洗槽温度95℃,碱浓度220-230g/L,淡碱回收浓度55-60g/L;
(4)染色工艺:染色采用分散/还原染料一浴法、分散/还原染料两浴法、分散/活性染料一浴法、分散/活性染料两浴法中的一种;染色后面料酸洗,酸洗后布面pH值6.0-7.0,酸洗温度50℃,增加中和酸渗透到纤维内部的速度,使酸液不仅仅浮于纤维表面,关键是酸液渗透纤维内部达到弱酸性,酸洗后水洗,充分洗去面料上反应生产的盐分,降低对后续三防整理的影响,水洗后控制布面含碱率小于0.05%;
(5)后整理工艺:浸轧三防整理液,烘干,烘焙;焙烘温度与时间的选择对于整理效果和生产效率尤为重要,然后保证有机氟高聚物充分交联或反应,保证布面温度160℃以上,焙烘时间要视设备和生产效率而定,烘焙工艺为:160℃,2min;或者170℃-180℃,1min;三防整理液:碳六三防整理剂60-80g/L,三防增进剂10-15g/L,柔软剂40-60g/L;三防整理液的化料顺序为:化料缸加水200L→柔软剂→三防增进剂→三防整理剂→加剩余水,调整到500L。
进一步的,退浆机前段工作液的化料顺序为:先放水200L→烧碱→渗透剂→分散螯合剂→退浆精炼剂→加水到500L,控制烧碱浓度在28-30g/L。
进一步的,退煮漂联合处理工艺中,水洗槽前3格85-90℃热水洗,第4格水洗槽75-80℃热水洗,第5格水洗槽温度控制在90-95℃,第6、7格水洗槽90-95℃,第8、9格水洗槽85-90℃热水洗,第10格水洗槽70-75度,第11格水洗槽30-40℃水洗;第12格水洗槽90-95℃,第13格水洗槽90-95℃热水洗,第14格水洗槽85-90℃,第15格水洗槽75-80℃,第16格水洗槽60-65℃热水洗。
进一步的,分散/还原染料一浴法工艺为:半成品→浸轧染料工作液→80-100℃热风烘干→195℃焙烘90秒→浸轧烧碱\保险粉工作液→102℃汽蒸60秒→水洗→皂洗95℃→水洗→烘干。
进一步的,分散/还原染料两浴工艺为:半成品→浸轧分散染料工作液→80-100℃烘干→195℃焙烘90秒→浸轧烧碱\保险粉工作液→102℃汽蒸60秒→水洗→皂洗95℃→水洗→烘干→浸轧还原染料工作液→80-100℃烘干→浸轧烧碱\保险粉工作液→102℃汽蒸60秒→水洗→皂洗95℃→水洗→烘干。
进一步的,分散/活性染料一浴法工艺为:半成品→浸轧染料工作液→80-100℃热风烘干→195℃焙烘90秒→浸轧活性染料固色液→102℃汽蒸60秒→水洗→皂洗95℃→水洗→烘干。
进一步的,分散/活性染料两浴法工艺为:半成品→浸轧分散染料工作液→80-100℃烘干→195℃焙烘90秒→浸轧烧碱\保险粉工作液→102℃汽蒸60秒→水洗→皂洗95℃→水洗→烘干→浸轧活性染料工作液→80-100℃烘干→浸轧活性染料固色液→102℃汽蒸60秒→水洗→皂洗95℃→水洗→烘干。
进一步的,染色后烘干,控制染料后面料含潮率小于1%,面料瞬时毛效小于10s。
进一步的,浸轧三防整理液后的烘干温度为80-90℃,烘干时优选非接触式热风烘干,现有的接触烘干时,烘筒的急烘易使整理剂发生泳移,并容易沾附轧辊,影响整理效果及正常运转,烘干采用低温80-90℃烘干,温度不宜过高,控制落布烘干,低温烘干有利于拒油的整理效果和耐久性;烘干温度过低,干燥不完全,影响拒污效果及其耐久性,且生产效率低,若温度过高,会使有机氟过早局部交联成膜,使织物内残留水分蒸发时,冲破纤维表面形成的薄膜,影响三防效果及其耐久性。
作为一个优选的技术方案,本发明所述的涤棉混纺纬向双包弹力面料的制备方法,具体包括如下步骤:
(1)退煮漂联合处理:
退浆机前段工作液:烧碱28-30克/升,退浆精炼剂6-8克/升,分散螯合剂2克/升,渗透剂2-3克/升;处理工艺为:履带箱温度101-102℃,堆置时间45min;工作液的化料顺序为:先放水200L→烧碱→渗透剂→分散螯合剂→退浆精炼剂→加水到500L,控制烧碱浓度在28-30g/L;水洗槽前3格85-90℃热水洗,第4格水洗槽75-80℃热水洗,第5格水洗槽温度控制在90-95℃,第6、7格水洗槽90-95℃,第8、9格水洗槽85-90℃热水洗,第10格水洗槽70-75度,第11格水洗槽30-40℃水洗;
