Development of standard soiled wool fabric for the performance evaluation in laundry of woolen products

以精纺毛纺及其机洗织物（去鳞型和BAP型）为研究对象，研究了抗缩整理对毛纺制品去污性能的影响。用色素、粘土和含油土壤混合剂研究了这些羊毛织物对人工污染的敏感性。在不同的洗涤条件下，用湿法或干法洗涤脏衣服。用K/S计算的去污力、索氏萃取法测定含油土壤、x射线荧光法测定氧化铁3个参数评价其污染程度和去除率。与未经处理的对照相比，去鳞羊毛和经bap处理的羊毛在洗涤后吸附和保留了更多的土壤。在水洗涤系统中，含油土壤的去除率与K/S的去除率一样低，而氧化离子对羊毛织物的去除率则相当高。防缩羊毛的干洗去除率较低。建议将羊毛织物预先浸泡在浓缩洗涤剂溶液中，作为提高衣物去污力的一种方法。

Worsted wool and its machine washable fabrics, descaled type and BAP type, were used to investigate the influences of shrink-resist finishing on soiling and soil removal properties of woolen products. The susceptibility of these wool fabrics to artificial soiling was investigated using a mixture of pigment, clay and oily soils. The soiled swathes were laundered under various washing conditions and washed by wet cleaning or dry cleaning. The degree of soiling and the soil removal were evaluated with three parameters, detergency calculated from K/S, measurement of oily soils by soxhlet extraction, and the determination of iron oxide by X-ray fluorescence analysis. Descaled wool and BAP-treated wool picked up more soils and retained more soils after laundry as compared with the untreated control. In aqueous washing system, the oily soil removal was as low as the detergency obtained from K/S, whereas ion oxide was considerably removed from wool fabrics. Detergency of shrink-proofed wools in dry cleaning was rather low. The preimmersing wool fabrics in concentrated detergent solution are suggested as a method of improving the detergency in laundry.
