木棉纖維的軸向結構分析

Longitudinal Structure of Kapok Fibers

摘要


在分析產品中木棉纖維剛度、強度的弱節基礎上,採用環境掃描電子顯微鏡、場發射掃描電子顯微鏡等詳細觀察了原生態木棉纖維和不同處理後的木棉纖維表面,肯定了木棉纖維的圓管狀細胞壁是由寬約5~10μm帶狀單元沿縱向螺旋狀繞成的。這種帶狀單元間的螺旋形接縫成為木棉纖維強度和剛度的弱節,受較大機械力快速作用或經強鹼腐蝕後會顯現原本5~10μm間距的螺旋形接縫,而受小應力反復作用後木棉纖維上則呈現出數倍於原始接縫間距的20~40μm的橫向折痕。

並列摘要


This paper focused on investigating the longitudinal structure of kapok fiber through the observation of residual deformation and fracture morphology of kapok fibers. By analyzing the surface morphology of kapok fibers before and after different treatments, we found that a kapok fiber is essentially constituted with 5-10μm wide strips that spiral along the fiber axis to form a tubular structure. The spiral seams appear to be the weak locations of the fiber and often the fracture or bending points when suffering a large force or repeated small forces.
