摘　　要：二甲基亚砜(DMSO)的溶剂残余含量是衡量PAN原丝产品性能的关键指标,是PAN原丝表面及内部形成缺陷的主要成因,其残余含量的高低直接影响PAN原丝成品的产量和质量。实验表明:采用浸洗加喷涌的水洗方式,通过提高水洗温度和循环喷涌量可以有效降低原丝中残余DMSO的含量,从而提高PAN原丝的产品质量。The residual solvent content of the dimethyl sulfoxide （DMSO） is a key to measure the performance of the PAN precursor products, is the main cause of formation of PAN precursor surface and internal defects, the residual content of PAN precursor manufacturing process will directly affect the yield and quality of PAN precursor products. Experiments show that washing by immersion and gushing is reducing the residual DMSO content in PAN precursor effectively. By improving the washing temperature, cycling gushing amount can improve the quality of PAN precursor products.
