Assembly mechanism and antistatic properties of wool fabrics with superfine graphene oxide

Abstract

Wool fabrics are preferred over synthetic and cellulosic fibers by consumers because of their good elasticity, warmth, and high moisture sorption. How to use new materials and new methods to break the bottleneck of high pollution and high energy consumption in wool dyeing and finishing, and develop new functional wool materials has become an urgent need of wool development. In this paper, wool is colored and functionalized with antistatic properties using one-step ecofriendly process by superfine graphene oxide (GO). The results of the assembly mechanism show that the adsorption thermodynamic behavior of GO on wool is more consistent with Langmuir model and the process is exothermic similar to the adsorption of conventional acid dyes on wool fibers. The kinetic behavior results indicated that adsorption behavior of GO on wool was identified, and the phenomenon was more in line with the quasi-secondary dynamics model. The antistatic test results showed that the antistatic performance of the wool fabric that was colored by GO was obviously improved and the half-life of the GO colored wool fabric could be as low as 0.17. The strategy of colored fabrics with GO and imparting additional functionality can provide a basis for the ecological processing and formation of wool fabrics with designed functions.
