The purpose of this work is to present three-dimensional models of plain fabrics having various warp and filling yarn diameters. In order to simulate a woven fabric, a 3-dimensional CAD software with NURBS modeling capability was used. Final rendering was performed on the fabric model. It was demonstrated that the changes in yarn diameter could be three-dimensionally modeled through the use of fabric geometry and the 3D CAD. A short RhinoScript program was composed to implement the data importing and model building on the 3D CAD.

The woven fabric composed of nylon 6 filaments was treated with aqueous solutions (20, 30, 40, 50, 60%) of formic acid at 3$0^{\circ}C$ for 10 minutes under unrestrained condition, and the shrinkage behavior and some kinds of properties were examined. The shrinkages of the constituent yarns and fabric were increased with formic acid concentration, but they were lower than that of the original filaments because of fabric-structural factors. And the shrinkage of the warp was lower than that of the weft because of the residual stress from weaving process. By the restraint forces such as fabric-structural factors and residual stress, the constituent filaments were damaged partially at 60% of formic acid concentration and the degree of damage on the warp was greater than on the weft. And though the fabric count were increased overall, the spacing between the warps was decreased prior to the weft and eliminated nearly at 60% of formic acid concentration. The thickness, tensile strength, elongation, and handle value of fabric were increased overall with formic acid concentration excepting that the tensile strength for both the warp and weft directions and the elongation for the warp direction were decreased instead by the damage of yarns. But the crease recovery was decreased except the case of the weft direction at 60% of formic acid concentration.

Demand for the fabric wipes is growing continuously. Wipes in industry are used for cleaning purpose. Cleaning involves rubbing action, so it is very important to know how much frictional force is encountered during the cleaning action. In this study the effects of normal load, sliding speed on frictional characteristics of nonwoven and woven wipes, both dry and wetted with different liquids, against glass and floor tile surfaces have been reported. With the increase in the normal load the coefficient of friction goes on decreasing for both nonwoven and woven wipes and this trend is observed in both dry and wet wipes. The coefficient of friction of both nonwoven and woven wipes against glass surface is in general higher than the floor tile surface. The wipes wetted with water shows an increase in coefficient of friction as compared to dry sample, but there is reduction in the coefficient of friction when the wipe samples are wetted with vegetable oil. In case of dry wipes, the coefficient of friction in case of nonwoven wipe is higher than the woven wipe. In case of woven wipes, the ranges of coefficient of friction either due to change in liquid type, normal load or sliding speed are in general smaller than that in case of nonwoven fabrics.

This research surveys the differences of fabric mechanical properties with the different looms and the fabric positions according to the warp and weft yarn tensions on the Vamatex and Omega-Panter looms respectively. For this purpose, the grey fabrics woven by PET filament using two test looms are dyed and finished. The processing shrinkages are measured on each processes such as dryer, scouring, pre-set, dyeing and final-set using the fabric density and width. The mechanical properties of the finished fabrics are measured and discussed with relation to the warp and weft yarn tensions of the two looms and the fabric positions. In addition, the fabric thickness according to the fabric positions such as right, left selvedges and center of the fabrics is also measured and discussed with the characteristics of the Vamatex and Omega-Panter looms.

This paper investigated the characteristics of the physical properties of woven fabrics according to the yarn structure and fibre property. It was found that wicking property of woven fabrics made of sheath/core hybrid yarn were better than those of siro spun and siro-fil hybrid yarns, which was caused by platform for transport of moisture vapor by filaments on the core part of sheath core hybrid yarns. In drying property, the fabric specimen woven by PP/Tencel sheath core hybrid yarns as a warp and Coolmax/Tencel spun yarn as a weft showed quick drying property, which was caused by the sheath core hybrid yarn structure as drainage of water moisture and coolmax fibre characteristics as quick dry material. Concerning to breathability and thermal conductivity as heat transport phenomena, it was observed that breathability of fabrics woven with hybrid yarns such as sheath core and siro-fil in the warp and hi-multi filaments in the weft showed the lowest water vapor resistance, which was explained as due to for air gap in the fibres of the spun yarns to restrict the wet heat transport from perspiration vapor. Thermal conductivities of the fabrics woven with PET/Tencel siro-fil yarns in the weft and hybrid yarns such as sheath core and siro-fil in the warp revealed the highest values, which was observed as due to higher thermal conductivity of PET than PP and more contact point between fibres in the siro-fil and sheath core hybrid yarns.

본 연구는 스마트 포토닉 의류 중 발광 의류에 적용될 수 있는 유연 광섬유 직물 디스플레이의 구현 방식을 고찰하였다. 유연 광섬유의 가공방법, 직물의 디스플레이 반사구조, 광원 색채에 따른 고유 휘도를 비교 분석하고, 이를 토대로 발광효과가 높은 광섬유 직물 디스플레이의 최적의 조건을 도출하고자 하였다. 광섬유가공방법은 '직물화전 에칭(Pre-etching) 방법'과 '직물화후 에칭(Post-etching) 방법'을 비교하였고, 직물의 디스플레이 반사구조는 '백색 직물(White Fabric)'과 '재귀반사 직물(Reflective Fabric)'을 사용한 두 경우를 비교하였다. 광원 색채는 RGB(Red, Green, Blue)의 휘도값을 비교함으로써, 유연 광섬유 가공방법과 배면소재에 따른 휘도값 차이를 광원 색채별로 비교 분석하였다. 분석 결과, 유연 광섬유의 가공방법과 직물의 디스플레이 반사구조의 두 직물화 방식의 변인 중 유연 광섬유의 가공방법이 직물의 디스플레이 반사구조보다 더 지배적인 영향을 미치는 것으로 나타났다. 유연 광섬유의 가공방법 중에서는 '직물화후 에칭' 방식이 '직물화전 에칭' 방식보다 광섬유 직물의 발광효과를 높이는데 좀 더 주요한 것으로 나타났고, 직물의 디스플레이 반사구조에서는 전반적으로 '재귀반사 직물' 배면이 '백색 직물' 배면에 비해 유연 광섬유 직물의 발광효과를 높이는데 더 효과적인 것으로 나타났다. 유연 광섬유 직물 디스플레이의 발광효과를 높이기 위한 최적의 구현 조건은 유연 광섬유의 '직물화후 에칭' 방식과 '재귀반사 직물'의 배면 배치가 조합되는 경우인 겻을 알 수 있었다.

This study is about the fabric attached to the relics excavated from the Shimchun-ri tomb of the 4th century and the Moonsan-ri tombs of the 5th century. We studied 5 pieces of fabric from the Shimchun-ri tomb: one piece was silk and the other four pieces were hemp. We were able to observe 8 pieces from the four tombs in Moonsan-ri, All of them except one ramie were silk. The two kinds of bast fiber found in the tombs of Shimchun-ri and Moonsan-ri were hemp and ramie, and they were found to be plain woven with S-twist thread which thickness is uneven. The density was more fine compared to the hemps found in the Kaya or Shinra tombs of the similar era. All of the silk textiles found in the Shimchun-ri and Moonsan-ri tombs used non-twisted thread, and were plain woven. Also, we found degummed and raw silk from the tombs. The average density of the silk textiles from these tombs are similar to other areas of the same time, and studies show that they used non-twisted thread in plain woven silk found in other tombs. Therefore, we can conclude that they usually used non-twisted thread when producing silk textiles.
