摘要：

为了降低机采棉清理工序对纤维品质的损伤程度,通过比较不同清理加工工序间纤维品质的差异,分析了籽棉清理和皮棉清理工序对纤维品质的损伤程度,探讨了最大限度降低纤维品质损伤的适宜机采棉清理道数。研究表明:机采棉每道清理工序均会对纤维品质造成损伤;籽棉清理对纤维断裂比强度的影响较大,较清理加工前平均降低了1.0 cN/tex,且以第2、3道工序的损伤最大;皮棉清理工序使纤维长度和整齐度下降了0.8 mm和1.7%,短纤维率增加了2.0%;第1道皮棉清理工序(含轧花工序)对纤维的损伤最大;籽棉清理工序可根据机采籽棉叶杂的清除难易程度,选择使用1~2道;皮棉清理可选择1道气流式皮棉清理机,或尝试不使用皮棉清理机。

Abstract:

To reduce the fiber quality damage caused by machine-harvesting and cleaning processes, the relationship between fiber quality and levels of cleaning were comparatively analyzed with regards to Xinjiang cotton. The optimum number of cleaning processes for machine-harvested cotton was determined based on minimal fiber damage. The results indicated that each cotton cleaner causes fiber damage, and seed cotton cleanings vary greatly in its effect on fiber strength with the strength reduction of 1.0 cN/tex. The declines during the second and third seed cotton cleanings, are greater than those during the first and fourth cleanings. Lint cleanings significantly reduce the fiber length and length uniformity index by 0.8 mm and 1.7%, and significantly increase short fiber index by 2.0%, and the greatest damage takes place during the first lint cleaning (included ginning). Therefore, differentiated selections of seed cotton cleanings should be adopted based on the level of leaf contamination by using 1 or 2 seed cotton cleaners. Lint cleaning should only use one air-type lint cleaner or this could sometimes be omitted.

Key words: machine-harvested cotton, fiber quality, cotton cleaning, fiber damage, cotton in Xinjiang
