摘要
以废旧涤棉混纺面料为原料,采用离子液体1-烯丙基-3-甲基咪唑氯盐([Amim]Cl)对含棉成分进行溶解回收,将得到的纤维素粉末与聚乙烯醇(PVA)、氯化钠(NaCl)配成纺丝液,用静电纺丝法制备出纳米纤维素纤维。通过发射扫描电镜进行观察并分析,研究接收板距离、推进压力、NaCl用量对纺丝效果的影响。结果表明:随着接收距离、NaCl用量的增加,纤维直径明显减小;随着推进压力的增大,纤维直径明显增大。
The cotton component in waste polyester/cotton blended fabrics are dissolved and recycled with ionic liquid 1-allyl-3-methyl imidazole chloride salt （ [ Amim] Cl） to dissolve recycling, the obtained cellulose powder is made into a dopo with polyvinyl alcohol （PVA） and sodium chloride （NaCl） , and then nano cellulose fiber membrane is prepared by using electrostatic spinning. Through the observation and analysis of the emission scanning electron microscope, the influence of the receiving distance, boost pressure and the amount of NaCl on the spinning effect is studied. The results show that with the increase of receiving distance and the amount of NaCl, fiber diameter significantly decreases; with the increase of boost pressure, fiber diameter increases obviously.
