纳米ATO粉体的制备及功能性整理

Preparation and Functional Finishing of Nano-ATO Powder

为促进纳米技术和功能性纺织品的发展,采用微乳液法制备了纳米ATO粉体,并将其对织物进行功能性整理。通过单因素试验,探讨了掺锑质量分数、pH值及反应温度对纳米ATO粉体粒径和电阻的影响;同时以静电压、半衰期和表面比电阻为指标,通过正交试验,分析了抗静电剂质量分数、黏合剂质量分数、浸泡时间及烘干温度对纳米ATO粉体功能性整理效果的影响。结果表明:纳米ATO粉体的最优制备工艺条件为:SnC14·5H2O∶SbC13=11∶1,溶液pH值3,反应温度60℃,烘干温度80℃,煅烧温度650℃;纳米ATO功能性整理最优工艺条件为:抗静电剂质量分数6%,黏合剂质量分数3%,浸泡时间30 min,烘干温度80℃。最优功能性整理工艺整理后,纳米ATO粉体均匀地分布在织物表面;同时织物经过50次水洗后,其抗静电效果仍然远远优于未整理前。

To promote the development of nanotechnology and functional textiles, nano-ATO powder was prepared with the microemulsion method and was used to functionally finish fabrics. Single factor test was carried out to investigate the effects of antimony-doped mass fraction, pH value and reaction temperature on the particle size and electrical resistance of nano-ATO powder. Besides, orthogonal test was conducted to analyze the effects of antistatic agent mass fraction, binder mass fraction, soaking time and drying temperature on the functional finishing of nano-ATO powder with static voltage, half-life and surface specific resistance as indicators. The results show that the optimal preparation conditions of nano-ATO powder are SnC14·5 H2O∶SbC13=11∶1, solution pH=3, reaction temperature 60 ℃, drying temperature 80 ℃, and calcination temperature 650 ℃. The optimal process conditions for functional finishing of nano-ATO are antistatic mass fraction 6%, binder mass fraction 3%, soaking time 30 min, and drying temperature 80 ℃. Under the optimal functional finishing process conditions showed that the nano-ATO powders were uniformly distributed on the surface of the finished fabric, and the antistatic effect of the finished fabrics was much better than that of the unfinished even after washing 50 times.
