【摘要】 采用介质阻挡放电低温等离子体对亚麻织物进行处理,引发接枝改性,采用混合丙烯酸和苯乙烯为接枝单体来减少均聚产物,以提高接枝率,改善亚麻织物的染色性能。确定了最佳工艺条件:等离子体处理时间为4 min,处理频率为3 kHz,处理电压为13 kV,接枝温度为60℃。采用红外光谱和X射线衍射对接枝共聚物进行表征,同时对反应机制进行了探讨。结果表明,亚麻大分子上接枝了丙烯酸和苯乙烯的混合单体,接枝亚麻对阳离子染料的上染率有所提高。更多还原

【Abstract】 The grafting of mixed monomer of acrylic acid and styrene onto linen fabric was carried out by dielectric barrier discharge low temperature plasma treatment,aiming at reducing homopolymer,increasing graft yield and improving the dyeability of the treated linen fabric.The optimum conditions were defined: plasma treatment time(4 min,) discharge voltage(13 kV,) frequency 3 kHz,grafting at (60 ℃.) Infrared spectrum and X-ray diffraction were used to characterize the grafted substrate,and the reaction mechanism was also researched.The results showed that the acrylic acid and styrene mixed monomer is grafted onto the linen macromolecule,and the dye-uptake of the grafted linen fabric for cationic dyestuff is improved.更多还原
