In this study, multi-component antistatic fibers with segmented pie structures were prepared by conjugate spinning of carbon black (CB)/polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) polymers. The antistatic property of the CB/PBT/PET fibers can be attributed to two factors: thorough mixing of the CB powder in the polymer matrix, and the close contacts formed between the segmented pie fibers. The fibers were woven and knitted into fabrics whose washing durability and antistatic properties were also tested. The surface resistivity of the woven and knitted fabrics did not change significantly (1.1 × 106 Ω/cm2 to 1.2 × 106 Ω/cm2) even after washing the fabrics 100 times. Thus, these fabrics can be used in a variety of applications that require antistatic materials.
