Study on the Properties of Coffee Carbon Filament Yarns

Abstract:

Coffee carbon fiber is a kind of functional polyester fiber. Waste coffee grounds is milled into nanometer powder and then added to the polyester spinning fluid. Coffee carbon filament yarns have the functions of antibacterial deodorant, sending anion, and thermal insulation. In this paper, the morphology and properties of coffee carbon filament yarns were tested, such as scanning electron microscopy, tensile, moisture regain and cohesion. Polyethylene terephthalate filament yarns were selected for comparison with coffee carbon yarns. The results show that coffee carbon powder is distributed both on the surface and inside of filament yarns; the moisture regain of coffee carbon filament yarns is higher than that of PET yarns; the strength and elongation of coffee carbon filament yarns and of PET filament yarns is close; the boiling water shrinkage of coffee carbon filament yarns is lower than that of PET filament yarns; the addition of carbon powder can not reduce the cohesion of coffee carbon filament yarns.
