Materials Technology
Development of new materials is a core technology that has walked together with human history and technology movement. Studies on modern technology of new materials is focusing on the extraction of synergistic properties through a fusion of individual materials, which requires a profound understanding on the chemistry as a fundamental of the material and the chemical engineering as a toolkit for the realization. Our research group is fully constructing systematic resources for materials design, synthesis, characterization and manipulation, particularly based on the specialized organic and polymeric materials, from which we are directing the development of versatile materials for biomedical, electronic and industrial applications. Furthermore, under the academic banner of °?sustainable growth°Ø for the next generation, we are currently emphasizing studies on environmentally benign and low-energy consuming materials and processing.

A good textile can be obtained by a good textile mechanical property. Textile mechanics is the study of the structure and mechanical properties of textiles. These two aspects are not independent. The mechanical properties must be explained by the structure, which they also help to elucidate. Because of this connexion, it is appropriate to study textile structures. For the yarn structure singles yarn, plied yarn, cords, core-spun yarns, bulked and stretch yarns are considered. For the fabric structure woven cloth(the plain, twill, sateen, and their derivatives), nonwoven webs, knitted fabrics(weft derivatives), nonwoven webs, knitted fabrics(weft and warp), braided structures, tufted fabrics, flocked materials, and stitch bonede cloth can be described by using various models.
There is a wide range of structures to be considered in the application of mechanics to the field of textiles, including: fiber structures, yarn structures, fabrics, and end items or garments. Fabers and yarns are often considered to be 1-dimensional in form; fabric, 2-dimensional in form; and garments, 3-dimensional.

The equations of the helical yarn geometry, the necessary fiber characteristics, the basic distribution of stresses and strains, the equation for the path followed by the migrating fibers, the conditions in which a fiber will slip, the actual distribution of tensions, the conditions for radial equilibrium, and integration over the whole section are considered for the yarn mechanics. Fabrics made from interlaced yarns have two structural properties: the arrangement of fibers within the yarn, and the arrangement of interlaced yarns within the fabric. The most used forms of interlacing are weaving, where two sets of threads cross and interweave with one another, and knitting, where the threads in one set interlock by looping. There are also other forms of interlaced yarn structures such as lace, crochet, and various types of net. Another fabric is a yarn sheet which is laid down without interlacing, so that it has no coherence until the yarn is bonded together.
