| 中文摘要 | 高強度、高模數聚乙烯醇纖維乃使用混合溶劑系統並使用交鏈劑以獲得,此乃將 硼酸交鏈劑加入 PVA NMP 及水混合溶液中形成紡絲液。 此外實驗所使用之凝固液及中和液 分別為氫氧化鈉甲醇溶液及硫酸甲醇溶液。本文乃使用乾噴濕式紡絲法紡絲。經熱延伸及熱 處理之聚乙烯醇纖維強度及模數可達 12g/d 及 160g/d。 初紡絲經熱延伸及熱處理後, 由 x- 射線繞射圖知,其為高順向,高結晶之纖維。 |
| 英文摘要 | The high tenacity and high modulus PVA fiber was manufactured by using a mixed solvent with a crosslinking agent. The boric acid was used as a crosslinking agent to add into a PVA NMP-water mixed solution to form a spinning dope. Besides, the methanol with sodium hydroxide and the methanol with sulfuric acid were used as the coagulation and the neutralization agent, respectively. The dry-jet spinning technique was used in the experiment. The tenacity and the modulus could reach up to 12 g/d and 160 g/d respectively after the as-spun fiber being heat-drawn and heat-treated. The fiber was found to be highly oriented and crystallized using X-ray diffraction technique. |
