Abstract

本发明为化工类，是以旧棉花为主要原料生产新棉花的技术，翻新的棉花色泽洁白且无菌无毒，可用于纺织、医疗卫生、民用棉、被套等，本发明的工艺流程是由旧棉花经过分选，热水预浸、用碳酸钠碱洗。洗衣粉清洗、漂白、丝光、用硫酸中和，干燥后送开松机、由打包机打包即成新棉花。

Description

本发明涉及为用旧棉花生产新棉花技术的工艺。
以前用过的废旧棉花，由于无翻新技术，因此不是废弃，就是由废品收购站回收。这样废物不能得到利用，又污染了环境。
本发明目的是为了扩大棉花来源，缓解棉花紧缺局面，提高旧棉花的利用价值，用旧棉花生产新棉花技术的工艺。
根据生产实践，认为纺织工业对棉布的某些整理工艺，可应用于对旧棉花的翻新上，并作了多次试验，找到了适用的工艺流程和工艺条件，完成了本发明。实践证明，其工艺合理，设备简单，投资少，见效快，原料来源丰富，成本低，经济效益显著，可变废为宝。采用本发明翻新的棉花，柔软洁白，无菌无毒。可用于纺织，医疗卫生，民用棉，被套等。
本发明工艺路线和工艺条件由以下实施例及其附图给出。
其生产工艺为：1、热水予浸锅，2、碱洗锅，3、清洗锅，4、蒸煮锅，5、漂白池，6、丝光锅，7、干燥器，8、开松机，9、打包机，10、漂液制备槽，11、液氯瓶，12、漂液泵，13、漂液澄清槽。
将废旧棉花根据其污染情况分选，秤量后将其放入热水予浸锅（1），热水温度60℃左右，开动搅拌器，浸泡3小时后，沥干后捞入碱洗锅（2），碱液是0.5%的碳酸钠溶液，温度55～65℃，不断搅拌，清洗40分，再用清水冲洗二次后捞入清洗锅（3），清洗液应该为0.5%的洗衣粉液，液温40℃，开搅拌机，清洗40分，再用清水洗2～3次，放入蒸煮锅（4），蒸煮锅（4）内是0.02%的烧碱液，开搅拌机，煮沸15～20分钟，再用清水漂洗，捞入漂白池（5），池内是0.5%的漂白液，液温37℃左右，开搅拌机，漂白1小时，再用清水洗干净。捞入丝光锅（6），锅内是0.5%的烧碱液，液温15℃左右，开搅拌机，丝光1分，再用清水冲洗干净用0.2%亚硫酸氢钠去除残氯，再用清水洗净，用0.1%的增白剂增白。用清水洗干净，用PH试纸测其碱度，用硫酸中和到PH7左右，用净水冲洗两次。沥干后送入干燥器（7），干燥后，送到开松机（8）开松后由打包机（9）打包。即成无菌无毒的洁白柔软的新棉花。
漂白液的制备：在漂液制备槽（10）内，以液氯与石灰乳在一定反应条件下制得（有效氯含量2.2%），由漂液泵（12）送入漂液澄清槽（13），澄清后供漂白工序使用。
A供水，B供蒸汽，C供漂液，D冷凝水，E液氯，F洗衣粉，G烧碱。
