This study investigated garment formability of the 73 breathable fabrics for sports-wear garment and their fabric mechanical properties were measured using KES-FB and FAST systems. Predicted garment formability from the mechanical properties measured using KES-FB and FAST systems was compared and discussed with fabric structural parameters. In addition, virtual 3D simulation silhouette by I-designer CAD system wear appearance by simulation using 3D CAD system. And compared with FAST finger chart by mechanical properties of FAST system. The correlation coefficients of extensibility and shear modulus between KES-FB and FAST systems were high, however, bending rigidity and compressibility showed relatively low correlation coefficients. The correlation coefficient of garment formability of breathable fabrics between KES-FB and FAST systems was 0.82. It revealed that garment formability can be predicted from fabric mechanical properties by KES-FB and FAST systems. The garment formability of nylon breathable fabric was higher than that of PET one, and the garment formability of laminated breathable fabric showed the highest value compared to coated, dot and hot melt laminated breathable fabrics. It revealed that garment formability of breathable fabrics for sports-wear can be predicted from fabric mechanical properties and garment formability was dependent on the materials, finishing method and fabric structural parameters.

This study examined the effect of the blend ratio of wool and polyester fibers, yarn and fabric structural parameters to the appearance property and the formability of worsted fabrics. The mechanical properties of twenty types of manufactured worsted and PET/wool blend fabrics were measured using KES-FB and FAST systems. Garment formability increases with the thickness and cover factor as well as increases with wool content. The correlation between KES-FB and FAST system showed a relatively high correlation with an extensibility of 0.98, bending and shear rigidity 0.71; both were higher than polyester synthetic fiber. The correlation coefficient of garment formability between KES-FB and FAST systems was 0.93 and the correlation coefficient between formability and fabric extensibility was 0.8. These results were higher than those of bending and shear rigidity. This revealed that garment formability was influenced by wool content, cover factor and fabric thickness; however, wool content and fabric thickness were the most important factors for the seam pucker. The garment formability of the worsted fabrics can be predicted by fabric mechanical properties measured from KES-FB and FAST systems.

Recently, the use of hazardous chemicals has been continuously increasing. Therefore, the international trade volume is growing and chemical accidents have increased. Nowadays, the safety awareness of the public has increased. As a result, the management and supervision of hazardous chemicals have been strengthened. However, the port policy of Korea has focused on increasing the volume of cargo through facility development. Thus, the port management of hazardous chemicals has been relatively neglected. For national economic growth and society, the port management of hazardous chemicals should be considered to efficiently ensure safety and economic growth. Therefore, this study assumed scenarios where hazardous materials were moved in a dangerous container, not only on appropriate wharfs but also in ports that were close to a big city. The BTX substances were selected among the toxic chemicals with large import and export volumes, and the risk distance and damage effects were predicted using various risk assessment programs. It is expected that this could be used to improve a port safety management system and could be utilized to determine the safety distance in case of an accident.
