用皮辊式轧棉机加工轧得的皮棉。外观形态呈薄片状。短绒及杂质含量较锯齿棉多，黄根较多，疵点少，主体长度较锯齿棉长。
测试锯齿棉时建议延长调湿平衡时间，测试皮辊棉时可适当增加测试次数，以确保测试结果准确。
Test results can be ensured accurate when prolonging adjust-humidity time for saw ginned cotton, increasing test number properly for roller ginned cotton.
通过正交试验分析了回潮率、相对湿度和测试次数三个因素分别对锯齿棉和皮辊棉断裂比强度的影响程度。
Effect degree of regain, relative humidity and test number on breaking tenacity of saw ginned cotton and roller ginned cotton were analyzed respectively through orthogonal test.
