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
