| 摘 要： | 研究了干 -喷湿纺聚丙烯腈 (PAN)初生纤维的喷丝头拉伸比和三级拉伸 (空气拉伸、DMF浴拉伸、热水和沸水拉伸、干热拉伸 )工艺中各拉伸比对纤维性能的影响。结果表明 :提高喷丝头拉伸比可明显地降低初生纤维的线密度 ,提高强度 ;三级拉伸工艺中各拉伸比的提高均有利于PAN纤维线密度的减小及其强度、声速取向度和抗张模量的提高 ;合理调配三级拉伸中各拉伸比可制得强度超过 7.0cN/dtex的PAN纤维

| Abstract: | The effects of the jet stretch ratio and draw ratios of three-stage drawing including air drawing, DMF bath drawing, hot water and boiling water drawing and dry-hot drawing on the properties of PAN fiber were studied in dry-jet wet spinning. The results showed that the increase of jet stretch ratio could greatly decrease the linear density of as-spun fiber and improve the strength; the increase of draw ratios in three-stage drawing process decrease the linear density of PAN fiber and improve the strength, sonic orientation and tensile modulus. The PAN fiber with strength higher than 7.0 cN/dtex could be produced by rationally adjusting the draw ratios of three-stage drawing process. |
