The purposes of the research were to find out the clothing construction factors of the mechanical industry working clothes by analyzing the working clothes supplied to 5 subject companies; and to suggest the optimized sewing conditions and the seam strength and elongation experimental data according to the clothing material and seam types implied to the working clothes collected. The fabric types and trimmings used for the mechanical manufacturing working clothes were Polyester/Cotton(65/35%), Polyester/Rayon(65/35%), Cotton(100%); and linings, interlining, various fastenings etc. 2 stitch types, i.e. lock and two-thread chain stitches were applied to the construction of the flat, lap felled, French, superimposed, lapped and bound seams for the seam strength and elongation experiment. The results derived from the experiment were as follows. (1) The seam strength results according to the seam types were high in the order of lap felled>lapped>flat, superimposed and French seams. (2) Considering the features of the seam construction, as the number of fabric layers at the seam line increased the seam strength also increased. (3) Apart from the highest seam strength from the experiment using the net lining with the main fabric, the seam construction consisting of two fabric layers with the interlining showed relatively high seam strength results. (4) The seam elongations according to the stitch types were high in the order of two-thread chain>lock stitches.

The purpose of this study was to research the effect of sewing threads on sewability. The materials used in this study were cotton threads, p/c spun thread, polyester spun thread and core-spun thread, which were the same in count, but different in fibers. In order to approach the purpose of this study, the change of sew-ability was measured according to the number of laundering. The results from this measure were as follows; 1. The order of seam strength according to the sewing threads was polyester spun threads, p/c spun thread, core-spun thread, and cotton thread in proportion to the loop strength of the sewing threads. The preserving rate of strength after laundering was the highest in core spun thread. 2. The order of seam elongation according to the sewing threads was polyester spun thread, p/c spun thread, core-spun thread and cotton thread in proportion to the elongation of the sewing threads. The preserving rate of elongation after laundering was the highest in core spun thread. 3. The order of seam puckering according to the sewing threads' was core-spun thread, p/c spun thread, polyester spun thread and cotton thread. The order of changing rate after laundering was the same as the former order. 4. The order of the needle temperature according to the sewing threads was polyester spun thread, core-spun thread, p/c spun thread and cotton thread.

Recently, the $"Optim"^{(R)}$ which is the wool fibre with high lustre developed by CSIRO in Australia is imported and commercialized as a high sensible fabrics for garment. But the price of this $"Optim"^{(R)}$ fibre is very high so material demand and supply is not smooth. This study is aiming to develop the drawing technology of the worsted yarn with washable function, lustre and low production cost. For this purpose, drawing yarns are made using developed drawing machine and high sensible fabrics are woven using this yarns, and various physical properties of the fabric specimen are measured and analysed with garment characteristics such as sewability and formability. The final objective of this study is seemed to be achieved by making the high sensible fabrics using drawing worsted yarns with high lustre such as $"Optim"^{(R)}$ fibre.
