| 摘要: | 本實驗以超高分子量聚乙烯纖維不織布經pH11 NaOH、pH3 H2SO4、pH3 HCl溶液浸泡三個月後，得知其斷裂強力分別下降約18%、20%、15%，伸度由原本之2.7%增加為3.31%、3.40%、3.33%，浸泡在pH11 NaOH溶液者纖維表面則因曾經膨潤又經烘乾脫去水分而出現軸向裂痕，浸泡於pH3 H2SO4、pH3 HCl酸性溶液者，其表面則有破裂及刻痕現象產生。
In the experiment, the non-woven fabrics made in UHMWPE was soaked in pH11 NaOH、pH3 H2SO4、pH3 HCl solution three months. We get the samples' strength at break decrease 18%、20%、15%, and the elongation at break increase become 3.31%、3.40%、3.33% from original elongation at break 2.7%. And the samples soaked in pH11 NaOH solution, its' surface of fiber get vertical fissures course of swellinged and dried by heat, the surface of other fibers that soaked in pH3 H2SO4 and pH3 HCl solution, there are broken surface and nicks. |
