Preparation and characterization of carbon black/polybutylene terephthalate/polyethylene terephthalate antistatic fiber with sheath–core structure

Abstract

In this study, antistatic sheath–core composite fibers with the core composed of polyethylene terephthalate (PET) polymer and a sheath composed of carbon black/polybutylene terephthalate (CB/PBT) polymer were fabricated using a conjugate spinning process. CB powders of various particle sizes were compounded with PBT polymers to prepare the antistatic CB/PBT pellets, and their electrical resistivities strongly depended on the intrinsic properties and dispersion of CB powders. The CB/PBT/PET fibers consisted of well-mixed CB powders within the polymer matrix showed an outstanding antistatic function, and they were employed to manufacture an antistatic glove with commercial acrylic yarns for practical applications. The antistatic glove with a reliable washing fastness is capable of being used on capacitive touch panels of smart phones, tablets, and other wearable electronic devices. This approach offers new possibilities for a variety of textile applications requiring antistatic properties.
