Fabrication and characterization of antistatic fiber with segmented pie structure

Abstract

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.

Fabrication of antistatic fibers with core/sheath and segmented-pie configurations

“…These results indicate the effectiveness of blending PBT with carbon black particles to increase the conductivity of PBT. The increased conductivity can be attributed to the π–π* electron transitions in the C=C bonds of carbon black [10].…”

“…In addition, the electrical resistivities of the DTYs are higher than those of the original fibers, which is most likely due to the deformation of the DTYs during processing, thereby lowering the degree of rigid contact between adjacent fibers. Previous reports have demonstrated that the presence of broken filaments and surface concaves are significant problems in DTYs because these affect the inter-filament contacts and electrical conductivity of such yarns [10]. As a result, the filler and the configuration and deformation of the fibers affect the electrical resistivity of the resulting product.…”

“…The materials used in this study, and their properties, are summarized in Table 1. The functional groups and the chemical properties of the materials have been characterized in the previous reports [7,10]. In the present study, the raw pellets were fabricated according to a previously reported method [11].…”

“…Such composite fibers, e.g. concentric core/sheath (Figure 1(a)), eccentric core/sheath (Figure 1(b)), 50/50 side-by-side (Figure 1(c)), unequal side-by-side, (Figure 1(d)), island-in-the-sea (Figure 1(e)), and segmented-pie fibers (Figure 1(f)), are widely manufactured in the textile industry [9–16]. Zhao and Liu [15] demonstrated that core/sheath fibers could reduce the energy consumption in the following application process, while side-by-side fibers can maintain their three-dimensional heterostructure after hot-stretching processing.…”

“…3 Furthermore, the lack of polar hydrophilicity of polyester fabric can also lead to the electrostatic accumulation of polyester fibers. [4][5][6] The rubbing motion leads to fibers repelling each other and generating static charges on the fabric surface, 7 which will affect comfort and limit their applications in apparel and home furnishings. 8,9 Static charge accumulated on the surface without appropriate dissipation, in certain circumstances, 10 can cause unwanted side effects such as attraction of dust, electric shocks, and even pose a fire hazard or lead to explosions.…”
