Description

一种新型环保低浴比面料染整工艺
技术领域
本发明涉及布料染整工艺,尤其是涉及一种新型环保低浴比面料染整工艺。
背景技术
染整工艺需要将布料经过前道处理后再放入染缸选用不同的浴比进行染色,染色处理工序完成之后进行相应的后整理,最后检验入库备用,完成最终的染整过程。其中浴比是纺织染整用语,指浸染方式织物与染液的比值。浴比是染色工艺的三要素之一,浴比的大小影响用水的多少以及燃料、助剂的用量,随着浴比的增加,吨纱用量的水、蒸汽、电、燃料、助剂等消耗增加。目前传统的染整工艺应用较多,但是存在工艺采用染色浴比大、需要用的染化料助剂多、染色工艺流程繁琐、工艺加工耗时长生产效率低、消耗大量能源、污染大的问题,而且在染色过程中的染料渗透性差,色量不稳定,从而导致加工后的布料产生色花、色差等瑕疵,在后整工艺复杂,容易出现锦纶纤维弹性以及强度损伤等问题,生产出来的布料不够蓬松,布料手感一般,影响成品的舒适度和透气性。

经过实施例1染整处理后的布料橙色稳定,效果更好,不会影响布料的手感和蓬松度,而且该染整工艺具有高效,节能,环保,节约成本的优点。
本发明改进的染整工艺的重点在于定型时,添加入低剂量亲水硅油环保手感助剂,这种助剂更偏向于亲水性能,从而进一步提高布料的吸湿性能,普通的助剂通常是采用柔软助剂,其目的是为了使布料定型后更柔软。而本发明工艺由于所纺织的布料已兼具轻、薄特性,其柔软程度能满足消费者需求,因此通过亲水硅油环保手感助剂增强产品的亲水性,从而进一步提高产品吸湿率,提升干爽保暖的优势。同时我们选择新型低浴比1:3-4的方法进行染整,这种低液比传统染整工艺比更加节约用水、减少污水排放,具有节能、环保的良好环境效益。
进一步说明,步骤1和步骤2的目的就是给予坯布适宜的条件,使坯布预先充分收缩,使坯布收缩而获得稳定或趋向于稳定。染色工艺采用1:3-4的小浴比,这样利于胚布收缩均匀。煮布工序控制温度升温至 98℃氨纶布的收缩率经试验可以达到接近其收缩峰值,有利于维持布料的缩张弹性。通过本发明提供新型环保低浴比面料染整工艺制备的布料具有舒适蓬松的手感,同时简化染整工序,提高生产效率,有效节约生产成本。
本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可不经过创造性劳动想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。
