项目摘要

This research investigated whether there is an effect or not as considering that polymer builder of Carrageenan is ingredient of detergent. Against an oxidation iron particle and pesticide, washing We are powerful and used to aim at a development of detergent and washing method to reduce the load for an environment.1. Removal of oxidation iron particle on fabrics by washing :We made it dirty with an oxidation iron particle of clothes, cotton, polyester, and washed clothes with PVA and S-PVA, CMC. The result, removing dirty with cotton sexually, with approximately 50%, Carrageenanng and CMC was an effect. However, the effect of removal from polyester was not recognized.2. Removal of standard soils on fabrics by washing :We washed artificial contamination cloth with mix system surfactant and polymer. As being the dirtiest well it was SAS in surfactans, and in the system with polymer, an effect was high for a mix of S-PVA and SAS.3. Removal of pesticide on fabrics by washing :For cotton, nylon, polyester fabrics on which pesticide was absorbed, we investigated to remove pesticide from fabrics under various washing condition. The depsorption of pesticide, in the case of cotton, was effective, washing whit only water. In the case of nylon, it was with SDS in alkaline at 40℃, it's most effective. In case of polyester, it was very difficult to remove pesticide, so we used organic solvents in polyester washing at 20℃, methyl acetate showed exceedingly. In washing at 40℃, the getergency of fabrics by using all of those solvents was over 80%.

本研究以卡拉胶的聚合物助剂为洗涤剂的主要成分，考察其对洗涤效果的影响。针对氧化铁颗粒和杀虫剂，洗涤我们是强大的，用于开发洗涤剂和洗涤方法，以减少环境的负荷1。织物上氧化铁粒的水洗去除：我们用氧化铁粒对衣服、棉、涤纶进行脏处理，用聚乙烯醇、S-聚乙烯醇、羧甲基纤维素钠对洗过的衣服进行清洗。其结果是，用棉花除脏，约占50%，卡拉胶和CMC是有效果的。然而，从聚酯中去除的影响没有被认识到。通过洗涤去除织物上的标准污垢：我们用混合体系表面活性剂和聚合物洗涤人工污染的布料。作为最脏的井，在表面活性剂中是SAS，在聚合物体系中，S-PVA和SA的混合效果很好。洗涤去除织物上的农药：对于吸附了农药的棉、尼龙、涤纶织物，我们考察了不同洗涤条件下织物上农药的去除情况。以棉花为例，仅用水洗涤，对农药的解吸是有效的。在尼龙的情况下，在40℃的碱性条件下与十二烷基硫酸钠混合，效果最好。对于聚酯来说，很难去除农药，所以我们用有机溶剂对聚酯进行了20℃的洗涤，醋酸甲酯表现得非常好。在40℃的水洗条件下，所有溶剂对织物的洗涤效果均在80%以上。
