At the 10th Textile Bioengineering and Informations Symposium held in Wuhan, China on May 16-19, 2017 (TBIS 2017), "Best Poster Award" (5 awardees of 83 posters) was awarded to Mr. SEITA Ryutaro, 1st grade Master course student, Department of Textile Sciences and Technology, Graduate School of Science and Technology (Supervisor, Assoc. Prof. WAKATSUKI K.), "Outstanding Student Papers Award" (5 awardees of 125 accepted papers) to Ms. YANG Liu, 2nd grade Master course student, Department of Textile and Kansei Engineering, Graduate School of Science and Technology (Supervisor, Prof. TAKATERA M.), and "Best Paper Award" (5 awardees of 57 accepted papers) to Dr. ZHU Chunhong, Assistant Professor, Department of Advanced Textile and Kansei Engineering, Faculty of Textile Science and Technology.
The title of the awarded poster "Evaluation of thermal protection of Japanese firefighter helmet and its improvement to thermal insulation" (Mr.Seita)
Research Outline : A Firefighter helmet plays an important role to protect the firefighter’s head from falling object, falls from a height and heat and flame from fire and heated smoke within a structure. A Japanese firefighter helmet is very light and comfort during their operation relative to Europe and North-America, but has problem heat resistance of shock absorption material such as polystyrene foam because it is polymeric. Therefore, protection of polystyrene foam from heat has very important role in terms of both skin burns on head and shock protection by object and fall. His research objective is to build up the test instrument on firefighter helmet against heat, investigate the thermal resistance on current Japanese firefighter helmet. Then, improvement to protect the polystyrene foam by cellulose fiber wipes has been proposed and investigated it performance by number of layers of the wipes.
It has been found that both installation of cellulose fiber wipes between helmet shell and polystyrene foam has insulated heat to polystyrene foam and absorption of water by the cellulose fiber wipes which released from aluminum hydrate as fire retardant for firefighter helmet shell made time delay to increase the temperature and maintain the performance of heat insulation. It is expected that this installation of paper wipes has great effect to maintain shock absorption even if the helmet is exposed to heat and flame for firefighter working environment.
The title of the awarded paper "Mechanical similarity for three-dimensional fabric drape considering bending rigidity and shear stiffness" (Ms.Yang)
Research Outline : Garment simulation has been applied into practice nowadays. However, simulated garments are still different from real garments due to fabric types and how to adapt mechanical properties of fabrics to required parameters in garment simulators is not specified.
We assume that if there is a mechanical similarity for fabric drape can be established, the simulation ability of a garment simulator can be evaluated by comparing simulation results of different fabrics for keeping similar drapes. In this study, to explore the similarity rule for fabric drape, drape tests were conducted using fabrics with different sizes. The relationship between drape coefficients and basic fabric mechanical properties was investigated, and the relationship among drape coefficients, mechanical properties of fabrics, and geometric parameters of drape tests was analyzed.
The title of the awarded paper "A design method of hollow structure woven fabric" (Assistant Prof. Zhu)
Research Outline : 3D hollow structural textiles are used for a wide range of applications, such as ordinary textile products, aircraft body or building materials as basic composite fabrics. The purpose of this research is to develop impact-resistant textile composites. Firstly a design method was proposed to weave 3D hollow structural fabric by dobby loom or Jacquard loom. In this study, we designed the hollow structure with [(N+1)-N] layer and expressed the number of wefts and warps of the minimum repeat using N as the number of layers and n as the number of interlacing. Moreover, by changing N or n, we were able to freely change the number of layers of the hollow structure and the size of the hollow. Finally, we simulated the shape of the hollow structure using Digital Fabric System and weave it with Jacquard loom.
