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。
