Description
技术领域
本发明涉及一种利用板蓝根天然染料染色处理再生纤维素纤维的方法及其在口罩中的应用，属于纤维染色领域。
背景技术
20世纪中后期，口罩的大规模使用次数明显频繁。载入史册的历次大流感中口罩在预防和阻断病菌传播方面数度扮演重要角色。制作口罩材料的不断更新，口罩过滤细菌的功能也得到了增强，口罩的类型逐渐增多，不但有多层棉布口罩，还增加了活性炭医用口罩、防尘口罩、普通纸口罩、工业口罩以及用“棉织布”制作的外科手术口罩。随着时代的发展，口罩产品不仅能够阻挡灰尘、飞沫，还能阻隔病菌、PM2.5等。2003年时中国发生了非典型肺炎疾病的传染，口罩的使用和普及达到新高潮，一场“非典”几乎令口罩一度脱销，各大药店门前拍着长长的队伍，人们争相抢购口罩。2009年，在继2004年的“禽流感”之后，“甲型H1N1流感”让口罩大军再一次出现在全世界各大新闻媒体的镜头前。
2013年1月9日以来，全国中东部地区陷入严重的雾霾和污染天中，防PM2.5口罩、空气净化剂、“宅家”、“银耳雪梨化尘润肺汤”等成为人们与污染抗争的直接“武器”。但是监测数据显示，形似防毒面具的“N95口罩”在淘宝网成交指数已激增10倍，说明口罩是人们与空气污染抗争最直接、最有效的方式，其在人们生活中发挥着不可替代的作用。
目前，市场上流通的普通口罩一般用脱脂棉纱布或无纺布制作而成，阻挡空气中悬浮的绝大多数粒径较大的灰尘颗粒，并不能有效地阻挡PM2.5、抗菌抗毒、提高免疫力、改善呼吸道疾病的功效，很大程度上影响了人们的身心健康。
板蓝根（常用别名：靛青根、蓝靛根、大青根）是一种中药材，为十字花科植物菘蓝的干燥根，通常在秋季进行采挖，炮制后可入药。其性寒，味先微甜后苦涩，具有清热解毒、预防感冒、利咽之功效，主要用于治疗温毒发斑、舌绛紫暗、烂喉丹痧等疾病。
随着人们生活水平的提高，人们对身体健康更加的注重，希望服装面料具有生态环保和保健等功能，因此使用天然染料进行纤维染色，符合市场的需求。
和化学染料不同，板蓝根染色不能一次成型，而是在染料浸泡一段时间后拿出来晾干，然后重新放进染缸里，直到用清水漂洗不退色为止，由于板蓝根染色染色方式落后，染色牢度不好，目前没有得到广泛推广。
现有技术中采用板蓝根染料进行纤维染色，存在以下不足：
（1）上染率低、固色率低；
（2）甲醛含量高；
（3）成品尺寸变化率高；
（4）染色牢度低，容易褪色，色差大；
（6）染料用量大，生产成本高，染色废水排放多，对环境造成污染。
现有技术生产的防雾霾口罩，存在以下不足：
（1）抗菌效果较差；
（2）化学染料染色面料存在过敏隐患；
（3）除尘效果差；对污染物的隔离效果差。
