棉纤维伸长是初生壁不断延伸的结果,不同棉种、品种的棉纤维伸长规律有一定差异。伸长期、伸长速度、快速伸长期等是影响最终纤维长度的主要因素。1　初生壁及其延伸棉纤维初生壁厚度约0.1～0.2μm,存在于整个纤维细胞的周边,其外为表皮层(厚度小于0.1μ)。初生壁在整个纤维细? Cotton fiber elongation is the primary wall of the continuous extension of the results, different cotton varieties, varieties of cotton fiber elongation has some differences. Elongation, elongation, rapid elongation and so on are the main factors affecting the final fiber length. Primary wall and its primary cotton wall extension of the thickness of about 0.1 ~ 0.2μm, exists in the perimeter of the entire fiber cells, the outer layer of the epidermis (thickness less than 0.1μ). Primary wall in the entire fiber fine?
