Abstract

Seam puckering and the seam strength of conductive threads used to produce smart clothing were analyzed according to stitching methods and fabrics. Samples were prepared in a lock stitch and zigzag stitch on plain woven and jersey knit fabric, using one type of polyester sewing thread and three types of commercial conductive threads that consisted of two types of stainless-steel conductive threads (TST and MST) and one type of silver conductive thread (SSV). Seam pucker percentages, shapes, and seam strength were measured. On plain woven fabric as well as jersey knit fabric, three-ply TST and MST showed a higher SP percentage compared to a polyester sewing thread. Meanwhile, single-ply SSV showed the lowest SP percentage. In addition, the SP percentage of the zigzag stitch decreased along the weft and course directions of the fabric, and decreased significantly as the number of fabric layers increased. Moreover, there was a marked tendency for a higher SP percentage in jersey knit fabric compared to plain woven fabric, and the two-dimensional cross-section waveforms of stitches obtained using three-dimensional data that showed increased irregular waveforms and peaks in the zigzag stitch. There were no correlations between seam strength and tensile strength.
