摘要
In this paper, UHMWPE filament yarns were modified to improve their surface energy using atmospheric pressure plasma pretreatment. Then, a novel method based on in-situ polymerization was used for the continuous fabrication of conductive UHMWPE/PANI composite yarn with a conductivity of 0.87 +/- 0.1 S/cm. Cylindrical plain weft-knitted fabrics with different densities were fabricated using conductive UHMWPE/PANI composite yarns, and their strain-resistance performances were studied in detail. The results showed that the resistance of the fabrics increased with increasing strain at a relatively low strain range, and it also exhibited good linearity, sensitivity, and repeatability, which were enhanced by increasing density. When the strain was relatively high, the resistance of the fabrics increased with increasing strain and then decreased when the fabrics were further stretched. The repeatability of the fabrics in the large-strain condition was worse than that in the small-strain condition. The repeatability of the fabrics was very different when comparing the first stretching and the second stretching, and the difference then declined and showed good repeatability after repeated stretching three times.
