The purpose of this study was to examine the effect of covering yarn's twist on mechanical properties of knitted fabrics of composite yarns with single covering process. Four yarns that were used in this study: two different composite yarns made from the four kinds of cotton and functional polyester-(Poly-A) with the ratio of 52:48, and the rest two yarns are the original cotton 100% yarn and the poly-A 100% yarn. The two kinds of composite yarns, CP1 and CP2, were processed on the single covering process. CP1 was applied on the single covering process with S-800 tpm, where Poly-A was used as covering yarn and cotton was used as core yarn. CP2 was applied on the same process as CP1 except that Poly-A had been applied on the two-for-one twisting process with S-400 tpm on the previous step. Sixteen mechanical properties of all the four knifed fabrics knitted under the same knitting conditions were measured by KES-FB system with the outer knit condition. And 3D CAD dressmaking simulations, which were driven by some of the mechanical properties, were presented. The results were as follows: CP2 had high RT values with twisting of covering yarn. CP2 also had high B, 2HB values because of higher linear density. SMD was affected rather by twisting of covering yarn than by fine hair of the cotton surface. Twisting of covering yarn made it decreasing T value and increasing W value. Dressmaking 3D CAD simulations showed that there are buckling effects on CP2 because of high bending rigidity and shear rigidity.

Silk fabrics are very popular and widely used because of their elegant appearance. However, silk fabrics generally have easy wrinkle, and do not stretch and deform permanently after machine washing. Then the stretched properties of silk fabrics are important for the application of industrial textile materials such as formal and sports wear. Thus, this research surveys the covering, weaving and degumming conditions for stretched silk fabrics. As a result, yarn breaking stress was reduced with increasing spindle speed, and the yarn twists were optimized under the covering condition of polyurethane/silk with PVA pretreatment. In addition, the shrinkage of the silk fabrics treated with star degumming process was reduced by continuous NaOH degumming process. The fabrics showed the fabric physical properties with optimum stretched properties and evenness surfaces.

Fabrics shrinkage are affected by weaving conditions and are very difficult to be estimated when the amount of fiber consumption and production are calculated. Therefore, we need to standardize fabric shrinkage according to various weaving conditions. To develop the new textile products, we collected and analysed data of fabric shrinkage with the weaving conditions including twisting and covering process and denier of yarns used.

This paper investigated garment formability and fabric mechanical properties of one-way and two-way stretch fabrics according to the thermal treatment methods. One-way and two-way stretch fabrics were woven using 75d and 150d PET/spandex covering yarns and then these were wet thermal treated with four kinds of finishing machines. The fabric mechanical properties of these stretch fabrics specimens were measured and compared with the regular PET fabrics. The stretch ratio of one-way stretch fabric was ranged 12 to 26 percentage, 15 to 45 percentage for 2-way stretch fabrics and 4 to 10 percentage for regular fabrics. Garment formability of stretch fabric was superior than that of regular fabrics, in addition, 2-way stretch fabric was better than one-way. The garment formability of the stretch fabrics treated with CPB and Lava wet thermal machines showed the highest values, and the stretch ratio of these 2-way stretch fabrics was also the highest, which was ranged 20 to 45 percentage. This phenomenon was assumed to be due to high extensibility and bending rigidity with low shear modulus of the 2-way stretch fabric treated with CPB and Lava wet thermal machines. It was shown that the garment formability of stretch fabrics treated without dry thermal treatment was higher than that of dry thermal treated fabrics. It revealed that high stretch fabric was available under the condition of low process tension in the wet and dry thermal treatments of the finishing process, which makes high garment formability.

저온기에 통기성 간이 피복재의 피복방법에 의한 보온환경이 잎상추의 생육촉진에 미치는 영향을 구명하기 위하여 농PO계 필름하우스내에서 '파스라이도' 피복재를 이용하여 직접피복, 터널피복 및 직접+터널피복 처리구 하에서 10월 13일부터 10월 31일가지 18일간 청상추와 적상추를 재배하여 그 효과를 검토하였다. 평균기온, 지온, 엽온과 상대습도는 피복의 효과가 현저하여, 직접+터널, 직접피복, 터널피복 및 대조구의 순으로 높았으며, 광합성유효광량자속은 역순위였다. $CO_2$의 농도는 주간보다 야간에 현저히 증가하였는데, 직접피복에서 가장 높았으며, 다음은 직접+터널피복, 터널피복, 대조구의 순으로 높았으나 그 차이는 매우 낮았다. 청상추와 적상추의 초장, 엽수 및 엽면적 등은 직접+터널, 직접피복, 터널피복의 순으로 촉진되었으나 통계적인 유의차는 없었다.

The purpose of this study was to investigate Renaissance wall-covering fabrics through Flemish paintings, that provides the details of the origin and development of background of modern wallcovering. The methods of the study are as follows. First, the background of textile development of Flanders in the 14^th to 16^th centuries were examined through a prior study. Second, the shape and use of wallcoverings in paintings painted during that time were analyzed and the process of changing to modern forms was studied. The residential environment with many stone buildings in relatively humid and cold weather created a need for decorative fabrics. Back then, the wool and flax fabric were not allowed to be worn on the body, so the materials were used for the development of interior fabrics. The characteristics of wall covering in Flemish paint can be summarized with movable, allegory, and decoration. Movable stems from the arrival of the emerging aristocrats of Flanders, who had enormous commercial trade and carried decorative fabrics; the mobility has become an allegory in reality as the royal and aristocratic use of wall-decorated fabrics is the symbol of authority. In addition, unlike Italy, where silk was procured from the East, fabrics manufactured using flax and wool were not suitable for clothing in terms of religion and practicality and were used to decorate walls.

본 연구는 복숭아 주간부 동해 예방을 위한 피복재의 보온성을 평가하기 위해 백색부직포, 황색일반지, 방수패드로 만들어진 피복재의 물리적 특성 및 보온성을 평가하고 실제 겨울철 복숭아 주간부 보온효과를 구명하여 피복재로서의 이용가능성을 검토하기 위해 수행하였다. 세 피복재 중 2겹방수패드 처리가 보온율과 열저항성이 가장 우수하였다. 2겹방수패드 처리의 주간단열효과는 $14.09^{\circ}C$ 만큼 온도상승을 차단하였고, 야간보온효과는 $7.23^{\circ}C$ 만큼 온도하강을 차단하여 보온효과가 가장 우수함을 확인하였다. 따라서 방수패드 재질을 보온피복재로 개발 보급할 경우 복숭아 주간부 동해 피해를 경감시키는데 도움을 줄 수 있을 것으로 생각되었다.
