The % by weight content of leaf-like, stem, boll, seed, and weed materials sifted (3360 mum greater than particle size greater than or equal to 595 mum) from visible wastes of the Shirley Analyzer was determined for a lint sample taken after ginning but before cleaning and for a second lint sample taken after one stage of saw-type cleaning. The % by weight content for bract and leaf increased with decreasing trash particle size. The content of cotton seed coat fragments decreased with reduction in trash particle size. Approximately 1/4 of the botanical wastes consisted of weed materials, including grass particles. Lint cleaning was ineffective in reducing the % by weight content of leaf-like trash. Some selective removal of stem trash occurred as a function of lint cleaning.
测定了从雪莉分析仪可见废料中筛出的（粒度大于3360微米且大于或等于595微米）叶状、茎、棉铃、种子和杂草物料的重量百分比含量，这些含量是针对轧花后但清洁前采集的皮棉样品以及经过一个阶段锯齿式清洁后的第二个皮棉样品测定的。苞叶和叶片的重量百分比含量随杂质粒度减小而增加。棉籽壳碎片的含量随杂质粒度减小而降低。大约四分之一的植物性废料由杂草物料组成，包括草颗粒。皮棉清洁对于降低叶状杂质的重量百分比含量无效。作为皮棉清洁的一个作用，会有一些选择性地去除茎部杂质的情况发生。
