  • This study aims to analyze the changes in the mechanical properties of woven fabrics(cotton, linen, wool, silk, and polyester) by bonding fusible interlinings with varying deniers(10D, 20D, and 30D) for a 3D virtual try-on system(one that a user to try garments through screens using Avatar) developed over the last decade. We experimented with four mechanical properties and thicknesses of twenty-three specimens of interlining bonded fabrics including face fabrics and interlinings by using the KES-FB-AUTO system. The results showed that the tensile property increased(LT and RT increased and WT decreased) as the denier of the interlining increased; however, the change was slight. In contrast, the bending and shear properties increased significantly as the denier of the interlining increased on both the warp and the weft. This showed evidence that the interlining gives the fabrics size stability. The compression property was slight changed as the tensile property varies depending on the fibers and the denier of interlining. As expected, the thickness increased by bonding the interlining as the denier of interlining increased. From these results, we conclude that 3D users need to reflect these changes of woven fabrics by bonding interlinings when they try screen fittings to accurately express the fabric reality of manufactured garment.

  • During high speed sewing, the needle thread is exposed to dynamic loading, short strike loading, inertia forces, friction, rubbing, force of check spring, bending, pressure, friction, impact, shock and thermal influence. The dynamic thread loading/tension alters throughout the stitch formation cycle and along its passage through the machine. The greatest tensile force occurs at the moment of stitch stretching, when the take up lever pulls for required thread length through the tension regulator. These stresses act on the thread repeatedly and the thread passes 50-80 times through the fabric, the needle eye and the bobbin case mechanism, before getting incorporated into the seam, which result in upto 40% loss in tensile strength of the sewing thread. This damage in the sewing thread adversely affects its processing and functional performance. In this paper, the contribution of dynamic loading, passage through needle and fabric, and bobbin thread interaction in the loss in tensile properties has been studied. It is observed that the loss in tensile properties occurs mainly due to the bobbin thread interaction. Dynamic loading due to the action of take up lever also causes substantial loss in tenacity and breaking elongation of cotton threads.

  • This study was accomplished to investigate drape coefficient and wrinkle recovery of brushed fabrics according to treatment processes and brushing conditions. For this study, grey fabrics of blended ratio of polyester 65% : cotton 35% were bleached and dyed. These fabrics were then brushed 1, 3, 5 and 7 times. Drape coefficient and wrinkle recovery of brushed fabrics were measured by drape tester and shirley crease recovery tester respectively. The experimental results were analysed statistically to relate mechanical properties, handle, drapability, and wrinkle recovery 1) Drape coefficients of dyed fabric showed lower values and wrinkle recovery showed higher ones than those of bleached and dyed fabrics. Especially dyed fabric brushed 3 times showed good appearance and form stability. 2) Considering the blocked properties that contribute to the drape coefficient and wrinkle recovery of brushed fabrics, bending and shearing properties had a high degree of correlation with brushed fabrics, and 2HB/W showed a high positive correlation with drape coefficient and a high negative correlation with wrinkle recovery.

  • This study was carried out to investigate the antifungal activity and house dust mite repellent effect of cotton and silk fabrics dyed with Juniperus chinensis heartwood extracts by hot-water and methanol. The chemical composition of Juniperus chinensis heartwood extracts by hot-water and methanol was analyzed by GC-MS. In the case of antifungal activity, dyed fabrics with hot water extract had no effect against chaetomium globosum fungus. But showing no growth in fabrics dyed with methanol extract, dyed fabrics with methanol extract showed very excellent antifungal activity. Silk fabric dyed with methanol extract showed excellent house dust mite repellent effect of 94.3%~96.0% against dermatophagodes farinae. The composition of Juniperus chinensis heartwood extracts from hot-water and methanol was different. There were no terpene and its analogue peaks in hot-water extract. However there were terpene and its analogue peaks in methanol extract. From these GC-MS results, terpene was identified in methanol extract of Juniperus chinensis heartwood. Efficient ingredient of antifungal activity and house dust mite repellent effect was assumed terpene.

  • Buddhist articles from various periods in the Vairochana Buddha statues, which are currently housed in the Haeinsa Temple's Supreme Buddha Hall and Beopbojeon Hall. This research concentrates on the artifacts found inside the storage boxes, which was placed inside the Buddha statues in 1490. A total of 24 pieces of fabric articles found inside the Virochana Buddha in Beopbojeon and 213 pieces from the Supreme Buddha Hall were examined. The types of textiles are as follows: bast fiber, silk, cotton, and union cloth. Bast fiber consisted of ramie and hemp. For silk, tabby woven with plain weave, spun silk, and thin tabby were found. And twill damask made with twill, Sa and Ra with the leno weave, and satin damask made with the satin weave were also found. Also the two Jeogoris and three Jogakbos were found, the one Jeogori was made with Hwan. The Buddhist articles in the Vairochana Buddha of Haeinsa have been preserved well and its colors have remained virtually the same from the time of its original placement. Therefore these articles are very important in understanding the textile characteristics, weaving techniques, dying techniques as well as traditional colors.

  • Recently, eco-friendly processing has been focused in the textile industry in order to reduce environmental pollutions. Applications of enzyme technology to the textile industry are an example of more environmentally compatible processes. However, there is not enough quantity of referring to denim fabric subjected to enzymatic treatment. In this study, depending on pH, temperature, cellulase concentration, and treatment time, the weight loss of denim fabrics was examined. Characteristics of enzyme-treated fabrics were measured by tearing strength, stiffness, and K/S values. The effect of a non-ionic surfactant (Triton X-100) on characteristics of the enzyme-treated fabrics was evaluated. The cellulase treatment condition on the cotton fabric were optimized to pH 6.0, 50C, 1%(o.w.f.), and 60minutes. Characteristics of denim fabrics by cellulase treatment in the presence of Triton X-100 did not improve because Triton-X inhibited the activity of enzyme.
