  • Smart sensors and connected devices have changed the concept of garments along with IT technology convergent garments that transform the performance of basic functions. Various types of products have been researched and developed due to the increased interest in smart clothing; in addition, studies based on physical and mechanical properties have also been actively studied to improve accuracy and reliability. This study represents a basic study for the development of smart textiles based on motion recognition for the surfing practice of beginners interested in IT convergence type. A physical durability evaluation of conductive yarn according to sewing method was later carried out. This study is a conditional specimen sewn with cotton lower thread and 100mm pattern length based on the results of previous studies. The durability of the conductive yarn according to the sewing method was evaluated according to the sewing method. Durability was evaluated by two kinds of repeated strain and abrasion tests. The specimen with applied cotton in a lower thread zigzag pattern 2mm stitch size 100mm stitch length was shown to have the most suitable durability for smart textile.

  • This study aims at the improvement of sewing function through understandings of dynamic property about the sewing methods and the thread material selection in knitwear. The tensile strength and shear of KES-FB and the Instron were measured for the analysis of the mechanical properties. The knit cloth was structured In the plain stitch, $1\times1$ rib stitch and $2\times1$ rib stitch with the combination of wool and cotton. With regard to the sewing method, intralooping and interlacing were applied. For thread materials, polyester, cotton, wool and silk were used. Since silk has the lowest extension and similar values regardless of its construction in intralooping, it is available knit apparel with uniform elastic recoverv. It also has small shearing resistance. It can be used in apparel which needs big mobility, but it causes rutting problem. Therefore, it is suitable to use intralooping. When the same sewing yarn and textile are use, it can lower shearing resistance and extension in intralooping, Since wool needs a lot of extension energy and it can be cut, intralooping is more suitable than interlacing in sewing of wool. In interlacing using polyester, extension and shearing resistance are high. Therefore, it is suitable for knit sewing with high massing. Silk is not suitable for interlacing since it can be rut. Even though knit materials are different, the RT values of polyester and cotton are similar in same construction. Therefore, they can be substituted each other considering resilience after sewing.
