Description

一种纺织印染用绿色环保食用级酸性体及其制备方法 技术领域
本发明涉及一种纺织印染用绿色环保食用级酸性体及其制备方法；属于纺织印染技术领域。
背景技术
目前，在纺织印染过程中使用的染色酸的品种有：硫酸、合成酸(染色酸)、工业级冰醋酸；这些产品属危险品，无论在运输及企业管理方面带来极大的不便及不安全性。而且，在纺织印染工业中使用上述染色酸存在对人体不安全因素；如，工人操作中，上述染色酸溅到工人皮肤上造成烧伤、烫伤留下永久的伤疤，溅到工人眼睛里的事件时有发生造成终身残疾。更让人担忧的是，目前采用上述染色酸制备的医用纺织产品(医用药棉、医用纱布、医用棉球、医用棉棒等)通常含有重金属，例如砷、铅、巩，达不到食用级安全级别。
发明内容
本发明的目的在于提供一种高效、环保、无毒、安全的纺织印染用绿色环保食用级酸性体；以替代现有染色酸，且能实现与现有染色酸相当、甚至更好的效果。
本发明还提供了该纺织印染用绿色环保食用级酸性体的制备方法。
为了达到上述目的，本发明采用的技术方案是：一种纺织印染用绿色环保食用级酸性体，其原料及重量份为：去离子水26-36份、过一硫酸氢钾4.6-6.8份、白醋10-16份和柠檬酸56-68份。
所述过一硫酸氢钾，又称单过硫酸氢钾，分子式是KHSO5。
所述白醋，是烹调的酸味辅料，色泽透亮、酸味醇正；含质量浓度3-5％的醋酸和水。
所述柠檬酸，一般为白色结晶粉末。
上述纺织印染用绿色环保食用级酸性体，优选组成为：去离子水26份、过一硫酸氢钾4.6份、白醋16份和柠檬酸60份。
白醋和柠檬酸均为食品级原料，使得本发明的产品环保、无毒、可食用。白醋与柠檬酸配合，一方面能使得柠檬酸能完全溶解、防止溶解后的柠檬酸结晶(柠檬酸结晶会导致纱线损伤)，另一方面能意外起到更好的皂洗效果。
上述纺织印染用绿色环保食用级酸性体的制备方法，包括以下步骤：
在反应釜中，将过一硫酸氢钾溶解于去离子水中之后升温至100-120℃，保温28min后降温至46℃；然后加入白醋搅拌6min，再加入柠檬酸、封闭反应釜、保温48min。
上述制备方法，为了使过一硫酸氢钾快速溶解于去离子水中，优选的将去离子水加热至46℃之后加入过一硫酸氢钾，并且在加入过一硫酸氢钾之后保温搅拌26min。
上述制备方法，“过一硫酸氢钾溶解于去离子水中之后升温至100-120℃”的目的在于：使制备的酸性体具备优异的杀菌、消毒、防虫、防霉变效果。
上述制备方法，各温度参数是经过大量实验之后获得的；只有在此温度参数下所制备的酸性体的各项性能才能满足“与现有染色酸相当、甚至更好的效果”的要求。
上述纺织印染用绿色环保食用级酸性体，作为染色酸，用于纺织品的印染过程中；使用温度范围：30-80℃；用量：0.5-1kg酸性体/100kg纺织品。
有益效果
本发明的酸性体：
1、无毒、安全、环保、可食用，而且与柠檬酸相比，具备价格优势；
2、皂洗效果好：能更好的络合浮色，使纺织品的颜色更艳丽、光亮；使用时无需额外添加皂洗剂；
3、络合水质中的钙、镁、砷、铅、巩等金属离子，使产品安全、无毒；使得印染后的纺织品的表面不会有一层白色；
4、具有较强的去污能力，能防止余色污染杂质；
5、处理后的纺织品的色牢度好，不褪色；能有效防止处理后的纺织品在使用过程中对其他产品造成二次污染。
