摘　　要：脂肪酸甲酯乙氧基化物(FMEE)具有较好的动物油脂乳化、蛋白质污垢净洗性能,在FMEE结构中引入PO基团,不仅能降低FMEE的泡沫,也能使FMEE具有一定的润滑性。在洗毛工艺中,PO基团封端FMEE可以在羊毛鳞片表面形成一层润滑膜,减少羊毛相互缠绕毡并。以PO基团封端FMEE为主体成分,通过复配调理剂6501、溶剂乙二醇叔丁醚、渗透剂伯烷基磺酸钠获得净洗、防毡并性能均衡的洗毛剂,通过试验确定了PO基团封端FMEE、调理剂6501、乙二醇叔丁醚、伯烷基磺酸钠的质量比为3∶2∶1∶1制得洗毛剂,该洗毛剂不仅能够去除羊毛表面的油脂、蛋白质污垢和沉积的金属皂,也能有效保护羊毛原有的弹性、强度、色泽等性能,使洗后的羊毛洁白、松散、不毡并。The fatty acid methyl ester ethoxide(FMEE)has excellent emulsifying property for animal fat and clearing power of protein fouling.The introduction of PO group into the structure of FMEE can not only reduce the foaminess of FMEE,but also increase lubrication force of FMEE.In the wool washing process,FMEE with PO ends can form a lubricating film on the surface of wool scales,which can reduce the wool intertwine with each other.Using FMEE in PO block as the main component,the conditioner 6501,solvent ethylene glycol tert-butyl ether and osmotic agent sodium primary alkyl sulfonate were mixed to obtain a cleaning,felt-proof and balanced performance wool washing agent.The proportion of FMEE in PO block,conditioning agent 6501,ethylene glycol tert-butyl ether and sodium primary alkyl sulfonate was determined to be 3∶2∶1 to produce wool washing agent.It can not only remove the grease,protein fouling and metal soap deposited on the surface of wool,but also effectively protect the original elasticity,strength,color and other properties of wool,so that the washed wool is white and loose without felting.
