摘　　要：以过硫酸钠为引发剂,研究了甲基丙烯酰胺在棉织物上的接枝共聚反应及其抗菌效果。分别测定轧烘焙工艺(DPC)和浸渍工艺对棉织物含氯量的影响,得到轧烘焙工艺最佳条件:引发剂和单体质量浓度分别为30 g/L和90 g/L,轧余率为76%,反应时间为3 min,焙烘温度和时间分别为150℃和1.5 min,最佳工艺含氯量为0.52%。浸渍工艺引发剂和单体质量浓度分别为30 g/L和50 g/L,反应时间为180 min,含氯量可达1.11%。利用红外光谱、SEM等对接枝织物的结构与性能进行表征,结果表明,自由基引发下棉织物可有效地接枝共聚甲基丙烯酰胺。抗菌结果表明,含氯量为0.52%的改性棉织物抗菌效果明显。The graft copolymerization and antibacterial property of methaerylamide （MAM） on cotton fabrics were studied with sodium persulfate as the initiator. The influence of pad-dry-cure process （DPC） and impregnation process on the chlorine content of the cotton fabrics was tested, respectively. In terms of pad-dry-cure process the optimum conditions of graft copolymerization were as follows： initiator concentration 30 g/L, monomer concentration 90 g/L, take up 76% , reaction time 3 min, and curing temperature 150 ℃ and curing time 1.5 min. With respect to impregnation process the active chlorine from the optimum process was 0.52%. The active chlorine reached 1.11% when the concentrations of initiator and monomer were 30 g/L and 50 g/L, respectively, after 180 min of reaction in impregnation process. The morphology and property of the grafted fabrics were characterized using FT-IR, SEM, etc. The results confirmed that methacrylamide was grafted onto cotton in radical-initiated polymerization. Tests showed that the modified cotton fabric with active chlorine of 0.52% exhibited good antibacterial property.
