Using FDM 3D printing, yarn shape and composition were modeled and 3D printed with PLA and TPU filaments currently used for apparel. Based on this, mechanical characteristics were measured to determine 3D printing yarn according to type of filaments in the 3D printed output and deformation and recovery characteristics due to differences in structure type. As a result of examining tensile and shear characteristics of PLA and TPU 3D printing compiles, TPU overall was measured with significantly lower stress than PLA. This is due to high elasticity of TPU's character, revealing that it has better flexibility than PLA. In addition, during deformation due to external forces, the more freedom between the head and foot parts of the loop, and the lower the force associated with each other, the more flexible it is. TPU revealed that it was easier to tension and recovery from tensile deformation than PLA, indicating potential for clothing materials using 3D printing. If high-molecular materials, such as PLA flexibility, it is likely to provide some flexibility through development of styles, including degree of freedom in modeling. Based on this, we provide basic data for developing 3D printing textures that can be satisfied with textile for apparel.

This research aim concerns questioning how we can generate environments suggestive of nature fused with built environments through textiles. Through literature reviews and experiments with available the 3D imaging techniques of Holography, Lenticular and other new technologies, We have researched towards finding the most effective method for 3D imaging techniques for textile applications. This objective is to produce intriguing textile patterns and images in which the objects and colours change as viewpoints change. Experimental work was carried out in collaboration with professional textile researchers, scientists, artists and designers conducting research in this field.

One way of appling 3D printing to garments is through the combination of 3D polymer filaments in textile fabrics. it is essential to understand the interface between the polymer and the 3D composite fabric in order to enhance the adhesion strength between the polymers and the peeling strength between the fabric and the polymer. In this study, the adhesion of composite printed specimens using a combination of fabric and polymers for 3D printing was investigated, and also the change in adhesion was investigated after the composite fabric printed with polymers was subjected to constant pressure. Through this process, the aims to help develop and utilize 3D printing textures by providing basic data to enhance durability of 3D printing composite fabrics. The measure of the peeling strength of the composite fabric prepared by printing on a fabric using PLA, TPU, Nylon polymer was obtained as follows; TPU polymer for 3D printing showed significantly higher peel strength than polymers of composite fabric using PLA and Nylon polymer. In the case of TPU polymer, the adhesive was crosslinked because of the reaction between polyurethane and water on the surface of the fabric, thus increasing the adhesion. It could be observed that the adhesion between the polymer and the fiber is determined more by the mechanical effect rather than by its chemical composition. To achieve efficient bonding of the fibers, it is possible to modify the fiber surface mechanically and chemically, and consider the deposition process in terms of temperature, pressure and build density.
