摘　　要：使用日本CM—70色度计与国产DSBD—1型数字白度仪,通过对纤维素织物白度的测量对比,筛选出适合于测量棉、涤棉、棉针织、亚麻、苎麻织物的白度B公式,B公式亦可简化用三刺激值Z值代替,使棉、涤棉、麻织物的白度测量既有效又方便。本文还探讨了纺织品白度与黄度的关系,提出用倒数关系表示之,即W·Y_1=1;B·Y_1=1;Z·Y_1=1。The formula B for whiteness evaluation of woven or knitted cotton, T/C blends, ramie and flax clothes is screened by comparative tests to determine the whiteness of cellulose fabrics using Japan - made CM - 70 spectrometer and home-made digital whiteness meter, respectively. Formula B can be simplified in terms of the amounts of three standard stimuli X,Y,Z to make the whiteness testing effective and simple. Furthermore, the relationship between whiteness and yellowness of textiles has been dealt with and proposed to be expressed in terms of reciprocal equation, that means W ?Y1 = l, B ?Y1 = l, Z ?Y1 = l.
