摘要：

针对腈纶织物在穿着过程中易产生静电的问题,采用传统的浸渍方法用氧化石墨烯溶液浸渍腈纶织物,然后进行热压,再经紫外光照射还原腈纶织物表面吸附的氧化石墨烯,以赋予腈纶织物抗静电性能。借助扫描电子显微镜表征腈纶织物吸附氧化石墨烯后的表面微观形貌;比较经不同温度条件浸渍处理的腈纶织物的颜色性能,研究温度对腈纶织物在氧化石墨烯溶液中浸渍吸附量的影响,并测试了紫外光还原前后织物的电阻率,研究其抗静电性能。结果表明:腈纶织物在90℃左右浸渍有较高的吸附量;经紫外光还原后织物电阻率为13 kΩ·cm,方阻为1.9 kΩ/□,符合抗静电性能标准;经水洗后,电阻率下降至29 kΩ·cm,水洗性能较好,皂洗牢度为4级,摩擦牢度为3级。

Abstract:

Aiming at the tendency of acrylic fabrics to generate static electricity during wearing, a conventional process was utilized to impregnate acrylic fabrics into graphene oxide (GO) solution. The acrylic fabrics were hot pressed followed by UV light irradiation to reduce graphene oxide on the surface for imparting acrylic fabrics to antistatic properties. The surface microscopic morphology of acrylic fibers was characterized by scanning electron microscopy. The influence of temperature on the color performances of acrylic fabrics was investigated. The antistatic properties of the fabrics were discussed based on the surface electrical resistivity of the acrylic fabrics. The results show that acrylic fabrics impregnated around 90 ℃ possesses a higher adsorption capacity. The final surface electrical resistivity of the acrylic fabrics after UV light reduction is 13 kΩ·cm and the square resistance is 1.9 kΩ/□, which meets antistatic performance standards. After washing, the electrical resistivity decreases to 29 kΩ·cm demonstrating excellent washing performance. The washing fastness is grade 4 and the rubbing fastness is grade 3.

Key words: acrylic fabric, graphene oxide, UV light, adsorption capacity, antistatic property
