Abstract

3D fabrics are in various forms and shapes and are used in different applications of technical textiles. The functional purpose of their use is primarily to create a barrier or maintain a distance between two mediums. Fabrics from knitting or weaving machines are mostly not in their end product shape. They have to be joined with different forms of joining methods, mostly sewing to obtain its final form. Usually the conventional method of sewing compresses the 3D fabrics at points of needle insertion and the fabrics do not perform along stitch line as they perform in rest of their plane. Spacer stitching is a new joining method developed, which particularly addresses the problems related to compressions along stitch lines. Spacer stitching samples are tested with skin model and the thermal resistance along stitch line are compared with conventional lockstitch sewing method. With the help of infrared technology, thermal emissions have been studied for spacer stitching and conventional lockstitch, compared and presented in this paper.
