HXFA299型棉精梳机梳理质量挖潜的实验研究

Study on carding effect of HXFA299 combing machine by changing carding degree

通过在HXFA299型棉精梳机上进行合理组合,得到4种不同的针面总齿数总和,对不同梳理度下精梳条梳理质量进行了研究。结果表明:锡林的梳理度对精梳条的质量指标有明显的影响,尤其是对棉结数、籽结数和短绒率的影响最为强烈;梳理度并非越大越好,必须结合所加工的品种和使用的纤维情况,通过实验得出最佳梳理度。

The quality of combed sliver under four kinds of different carding degree is studied on the HXFA299 combing machine. The fact shows that effect on comber quality improvment through modifying carding degree is remarkable, particularly of the Nep（cnt/g）, SCN（cnt/g） and SFC（w）%. It is not correct that the bigger the carding degree the better. User must search for the most suitable carding degree by testing.
