군용 방한복 상의 내피 원단은 원단과 패드타입 솜을 누빔(퀼팅)하는 형태로 제조되어 보온성을 부여하고 있다. 이렇게 제조된 방한복 내피 원단을 퀼팅원단이라고 하는데, 퀼팅원단은 윗실, 밑실이 각각 교차하여 원단과 솜을 같이 봉제하는 형태로 견고하게 제조되는 것이 일반적이다. 따라서 제조된 퀼팅원단에서 원단과 솜을 분리하는 것은 거의 불가능하며, 이를 분리할 경우 원단 및 솜에 상당한 손실을 가져올 수 있다. 본 연구에서는 퀼팅원단을 제조한 뒤 원단을 손상시키지 않고 후속가공을 통해 보온력을 증대시키고 두께 변화율을 안정화 시키는 방법에 대해서 연구하였다. 일반적인 솜 생산 시설 중 일부 설비를 이용하여 퀼팅원단을 통과시키는 비교적 간단한 방법을 통해 연구를 수행하였고 다음과 같은 결과를 얻을 수 있었다. 보온성의 경우 후속가공하기 전 퀼팅원단에 비해 clo값 기준으로 약 10 %가 상승한 효과가 나타났으며, 세탁 두께 변화율은 후속가공하기 전 퀼팅원단에 비해 약 10 % p. 안정화된 효과를 보여주었다. 이는 퀼팅원단 제작 후에도 후속가공을 통해 보온성을 향상시키고 세탁에 따른 두께 변화율을 안정화 시킬 수 있음을 나타낸다.

In this study, we constructed a database of dyeing concentrations of all reactive dyes used for dyeing linen according to the thickness of the linen fabric and attempted to improve the reproducibility of the dyeing process for the commercialization of linen fabric materials. Linen fabric is a natural cellulose material that is comfortable and suitable for eco-friendly trends. It is a typical summer material with excellent breathability and thermal conductivity, quick moisture absorption and dissipation, and a cool touch. Dyeability and fastness were evaluated depending on the thickness of the linen fabric using a monochlorotriazine (MCT) reactive dye and bifunctional yellow, red, and blue dyes. All three colors of the MCT reactive dye and bifunctional dyes exhibited a darker shade as the fiber thickness of the marker increased. Fastness to washing was excellent at grades 4-5 or higher, regardless of the color of the dye and the number of linen fabrics. Although some color-fastness differences were noted, with the color change occurring most frequently with blue color, the fastness variations with dye type were mostly similar. The results of this study are expected to facilitate the selection of reactive dyes according to the thickness of the linen fabric based on the basic data from the laboratory, which will aid in the mass production of linen fabric and benefit the fashion industry.

Effects of plating conditions (dispersant concentration, plating time, and ultrasonication) on electroless Cu plating on SiC fabric woven by crossing of SiC continuous fibers vertically were studied. The ultrasonic dispersion treatment not only did not improve the dispersion of the SiC fibers, but also did not change the plating thickness. The ultrasonication in the pretreatment step of electroless plating did not improve the dispersion of the fibers, while the ultrasonication in the plating step enhanced the dispersion of the fibers and decreased the thickness of the Cu films. It was possible to control the thickness of the Cu coating layer as well as the dispersion of the fibers in the fabric by changing the plating conditions such as dispersant concentration, plating time, and ultrasonication, but it was very difficult to coat copper on the intersection of vertical fibers in the fabric.

Fabric touch was evaluated psychophysically in order to determine the relationship between mechanical properties and subjective sensation. For subjective touch sensation, eight aspects such as hardness, smoothness, coarseness, coolness, pliability, crispness, heaviness and thickness were evaluated using free modulus magnitude estimation (FEME) technique. KES-FB was used to measure the mechanical properties of fabrics. Woolen fabric with the highest values of WC and weight was evaluated as the coarsest, heaviest and thickest. While silk crepe do chine with the lowest LT, G, 2HG, thickness and weight was rated as smoother and more pliable than any other fabrics. And flax with the highest values of LT and SMD was evaluated as hard, cool and crisp. Fabric touch and satisfaction were predicted well from the mechanical properties, especially from SMD, by regression analysis. Satisfaction for touch increased as smoothness increased.

To examine the effect of heat treatment temperature in finishing process on PET/PBT Fabric, PET/PBT Fabrics were treated at different relaxing temp., pre-set temp., and final-set temp.. The dimensions such as thickness and density were measured, and the handles were evaluated by Kawabata system. In relaxing which was wet heat treatment, thickness and bulkiness were increased, and NUMERI, FUKURAMI, SOFUTOSA, and THV also were increased but KOSHI was decreased with elevating temperature. With elevating pre-set temp., thickness and bulkiness were decreased, but KOSHI was increased. NUMERI, FUKURAMI, SOFUTOSA, and THV were the best at 180$^{\circ}C$ pre-set treatment. In final-set which was dry heat treatment like pre-set, thickness, bulkiness, NUMERI, HUKURAMI, SOFUTOSA, and THV were decreased, but KOSHI value was increased with elevating temperature. Therefore the best heat treatment condition was 130$^{\circ}C$ relaxing, 180$^{\circ}C$ pre-set, and 160$^{\circ}C$ final-set. And the handle of PET/PBT Fabric was affected much more by relaxing temp. than pre-set temp. and final-set temp.

In this work, the carbon fabric reinforced phenolic composite is applied for heavy-duty journal bearings. The through thickness compressive strength (TTCS), which is one of the most important characteristics for the bearing material, is measured and analyzed with respect to the stacking sequence and composite thickness. Also, the coefficient of thermal expansion (CTE) and thermal conductivity of the composite in the thickness direction were measured with respect to stacking sequence.

The purpose of this study was to compare the efficiency of four different cleaning method of silk and to fabrics, which were excavated from the sixteenth century tombs. The four cleaning methods were hand washing in water and hand washing in solvent, washing in ultrasonic cleaner, and using of ultrasonic gun after washing in ultrasonic cleaner. The following is the result of the experiment: ㆍBoth silk and jute fabrics shrank the most after hand-wash in water. This cleaning method decreased their thickness the most but changed their strength the least. However, the color of the fabric changed the most after had-wash in water. This washing method might discolor the dyed fabric, so one must check the condition of the fabric thoroughly before washing it. ㆍThe weight and the thickness of the fabric changed little after ultrasonic cleaning. This cleaning method, therefore. is less efficient than hand-water-wash. The use of ultrasonic gun after ultrasonic wash for partial cleansing enhanced the efficiency a little. Nevertheless, this method left stain around the area where the gun was used, and the injected water could damage the fabric. ㆍThe excavated fabric became softer in the cleaning process as the dirt was washed away. In both cases of silk and jute fabrics cleaning, solvent made the fabric softer than water. Washed in solvent, the fabric did not swell. But water penetrated to the fiber during the cleaning process and made the fabric swell. When the water evaporates, the swollen fiber structure collapses and the fabric become stiff. Ultrasonic wash did not cause much change in the flexibility of the fabric, for this method does not remove the dirt as effectively as the other method.

This study aimed to visually compare the implementation of digital virtual fabrics for stretch fabrics mainly used in clothing that closely touch the body, using CLO. A digital fabric was used in CLO after measuring the weight, thickness, bending, and tensile force of five adhering clothing fabrics using a CLO fabric kit. The visual similarity of draftability was compared by measuring the area of the bending angle and the shape of the wrinkles of the real and digital fabric. A comparison of the bending angles showed that Fabric A was -0.75° and Fabric D was -2.5°, showing slightly lower drape properties than the real fabric. Meanwhile, Fabric B was 2.75°, Fabric C was 2.13°, and Fabric E was 1.375°, showing slightly higher drape properties in the vertical direction than the real fabric. Comparing the widths of the drape shapes, Fabric A was 0.77%, Fabric B was 1.27%, Fabric C was 0.06%, and Fabric E was 1.48%, which showed a slight difference. Fabric D showed a difference of 3.17% and was implemented where the digital fabric spread a little wider. As a result, the stretch fabric was visually expressed similarly to the real fabric as a whole in CLO. For 3D virtual clothing technology to be used widely in the close clothing industry in the future, more research on real clothing is needed.

This study was carried out on the Sewbility of Urethane Foam usually used as coldproof lining. The Sewability was estimated with the Puckering Grade and Seam Efficiency according to the thicknes of urethane foam, fineness and material of sewing thread, and the sort of covering fabric. The result shows the following ; 1. The thick foam proportinally shows the low Puckering Grade. 2. Effect on the sewability is small in fineness of sewing thread but large in material. Especially silk thread shows the greatest sewability in foam sewing. When the material of covering fabric is same as that of sewing thread (for example ; p/c fabric and p/c thread) the sewability is excellent in special. 3. Taffeta in covering foam is not suitable to foam sewing, satin and twill show superior sewability without reagrd to the thickness of foam. 4. In case of sewing foam covered with tricot, optimum thickness of foam and fineness of sewing thread through pretest must determine. 5. The thicker foam is the better seam efficiency tends, and Seam Efficiency largely effects to the strength of the sewing thread itself. 6. The seam Efficiency can heighten with the strength of sewing thread in proportion to that of covering fabric.

This study investigated water vapor permeability of the 73 breathable fabrics for sports-wear according to the materials, finishing methods and fabric structural parameters. The water vapor permeability by KS K 0594 method of PET breathable fabric was superior than that of nylon one, in addition, water vapor permeability of coated or laminated breathable fabrics were higher than those of hot melt or dot laminated fabrics. The water vapor permeability of breathable fabric was dependent on the thickness, weight and density, which was consistent with measuring method. However, water vapor permeability according to materials and finishing method showed different results according to measuring method. The correlation coefficient of WVP of PET breathable fabrics between ISO and KS K measuring methods was -0.83 and the correlation coefficient of WVP of coated breathable fabrics was -0.72 and -0.71 for KS K and ASTM and -0.72 for KS K and ISO in hot melt laminated breathable fabrics. According to regression analysis, WVP of PET breathable fabric by both KSK and ISO measuring methods was highly dependent upon on the density and weight. In addition, WVP of hot melt laminated breathable fabric was highly dependent upon thickness, weight and density. Therefore, relevant measuring method for WVP of breathable fabrics has to be adopted to measure precise breathability.
