摘要
棉花的粘着性是衡量棉花质量好坏的一个重要指标 ,许多国家的农学家和仿织学家对此都作选大量的研究工作 ,研究的主要范围是棉纤维中水溶性的成份及棉纤维外附着的外来物 .就棉纤维表面生理结构而言 ,目前研究很少 .一般认为 ,棉纤维呈圆柱状 ,纤维表面是光滑的 ,笔者以新疆长绒棉为研究对象 ,用日立 S- 57日扫描电镜 ,研究了棉纤维的表面结构 ,结果表明 ,棉纤维并非呈圆柱状 ,自然状态下呈螺旋形 ,象氨基酸那样 ,根据概率估计 ,没有扭曲的约占 1 5% ,棉纤维表面并不光滑 ,有毛刺 ,这种结构特性是影响棉花粘着性的又一重要因素 .
Stickability is a important index of measuring the quality of cotton.Many agriculturist and textile specialist have made a great deal of research in the water soluable compositions and extraneous attaching substarces of cotton fibre.But little research work is made in the surface structure of cotton fibre.Generally,it is considered that cotton fibre is a column and its surface is smooth.The surface structure of Xinjiang long fine hair cotton is researched by using electronic microscope scanning (S 570 Japan)..The result shows that the cotton fibre is not a column,but is spiral.The fibre of only 15% does not twist.The surface of the fibre is not smooth,and there are burrs on it.These characteristics would be another important factor effecting the stickability of cotton.
