摘　　要：To enhance the hydrophilicity and antistatic properties of the polyethylene terephthalate(PET)fabric,the lawsone dye was employed in dyeing the PET fabric.It was dissolved in ethanol/deionized water mixture and deionized water separately,forming different lawsone dye solutions(LDSs).The study investigated how the compounds in the LDS improve the surface properties and color durability of the PET fabric,resulting in increased dye uptake.An infrared dyeing machine was utilized to expedite the reactions between the lawsone dye and the PET fabric.Additionally,the chemical composition of the dyed PET fabric was verified using techniques such as Fourier transform infrared(FTIR)spectroscopy,X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD)and ultraviolet-visible(UV-Vis)spectrophotometry.The K/S value was measured to assess color durability.After dyeing,the PET fabric exhibited high hydrophilicity which improved the hygroscopicity of the PET fabric and thus the conductivity of the PET fabric surface increased,thereby providing an antistatic effect.为了提高聚对苯二甲酸乙二醇酯(polyethylene terephthalate,PET)织物的亲水性和抗静电性能,使用指甲花醌染料对PET织物进行染色。指甲花醌染料分别溶于乙醇/去离子水溶液和去离子水,制得不同指甲花醌染料溶液。探讨了指甲花醌染料如何改善PET织物的表面性能和颜色耐久性。使用红外染色机加速指甲花醌与PET织物之间的反应。采用傅里叶变换红外光谱、X射线光电子能谱、X射线衍射和紫外-可见分光光度法等技术验证了染色PET织物的化学组成。通过测定K/S值评估颜色耐久性。染色后,PET织物表现出高亲水性。这提高了PET织物的吸湿性,增加了PET织物表面的导电性,使PET织物表现出抗静电效果。
