This study is to understand the actual condition of design and material of peanut-shaped diaper with looking at the types and characteristics of baby cloth diapers and domestic peanut-shaped diapers registered in the Patent Office. Furthermore, it is to suggest the basic data for designing more functional and comfortable cloth diapers. Here are the research result on the actual condition of design and material of baby cloth diapers. Firstly, 11 cloth diapers registered in the Patent Office can be divided into panty-shaped and straight line-shaped diapers. There are 7 kinds of panty-shaped cloth diapers which satisfy both the convenience of a disposable diaper and sanitation of a cloth diaper, and 4 kinds of straight line-shaped cloth diapers that minimize the weaknesses of existing cloth diapers. Secondly, domestic peanut-shaped cloth diapers can be divided into peanut-shaped, inserted, winged, velcro-attached diapers. Among 23 kinds of peanut-shaped cloth diapers from 16 companies, there are 12 kinds of peanut-shaped diapers which consist of layers of cloth to make peanut shape. There are 6 kinds of inserted diapers that insert extra diapers or handkerchiefs in between two sheets of cloth diapers and 3 kinds of winged diapers designed to shorten drying time with sawing only one side of several layered sheets. Also, there are 2 kinds of velcro-attached diapers that are removable according to the amount of excreta. Commonly used materials are cotton woven of diamond jacquard and knit of diamond Hole Stitch or Plain Stitch. And for handing the edge of diaper, the method of wrapping up the edge with cotton woven or knit bias is used.

In a PEM fuel cell electrode, backing layer has tremendous impact on electrode performance. The backing layer provides structural support for the porous electrode, distributes the reactants to the other layers and acts as a current collector. It has major influence on the water management in a PEM fuel cell. Selection of suitable backing layer material for the fabrication of electrode is thus very important to achieve high performance. In this paper we have compared the performance of PEM fuel cell electrodes fabricated using carbon paper EC-TPI-060T, carbon cloth EC-CCI-060T, (ElectroChem Inc.USA) and Carbon cloth from Textron, USA (CPW 003 grade). Mass transport problem was observed under non-pressurized condition, at high current densities, in the caie of EC-CC1-060T carbon cloth electrode (at $50^{\circ}C$), due to its higher thickness. The performance of carbon paper electrode was higher than EC-CCI-060T carbon cloth electrode. The performance of Textron carbon cloth was comparable to EC-TPI -060T carbon paper.

The purpose of this study is to analyze Kapa, the traditional bark cloth of Hawaii, including materials, method of manufacture, and colors and patterns, and to show the characteristics of Kapa to identify traditional culture of Hawaii as well as the unique culture of cloth of Hawaii in tropical area. The method of study is qualitative research using documentary records about Kapa. The cultivated Wauke proved to be the best material for bark cloth in Hawaii. The manufacture of Kapa was made by beating divided into two stages. The dyes for coloring were very different due to the existence of various plants. Indigenous Hawaiians showed the unique textures like grooving and watermarks, and the various designs in their Kapa. The characteristics of Hawaiian Kapa appear the symbol of some colors, the preference of geometrical patterns, the various uses of Kapa, and perfumed Kapa. Through these characteristics of Hawaiian Kapa, the traditional culture of indigenous Hawaiian can be understood very well. This study will help people understand indigenous bark cloth of tropical areas including Hawaii.

The cultural properties of cloth are of animal orgin (silk), or of vegetable orgin(cotton, hemp, ramie). As clothes are of an orginic material, they were subjected to damage by chemical, phisigical or biological factors, viz, moulds insects, lights, humidity and temperature changes, etc. And these factors promote that clothes generally result from various types of deterioration. In 1992, We were performed the conservation treatments for total 9 pieces of cloth, such as 3 pieces of General PAK SHIN-RYONG(Important Folklore Material No.110) 3 pieces of Madam Jung(Important Folklore Material No.115) and 1 piece of King Se-jo(Important Folklore Material No.219). The procedure of the conservation treatment for clothes describe the following below. 1) The washing and dry-cleaning to remove the contaminated substances from cloth was used 0.2% stearyl potassium soap solution and the mixture solution compound of n-Hexane, C6H14. and n-Decane, C10H22. And after the washing and dry-cleaning, the dry of clothes was carried out in a warm condition. These steps were repeated in 2 times over for each cloth. 2) The repair of clothes was attached the similar textiles to stronger fabric linings by needlework.3) The reprodution was made for cloth of King Se-jo to equalize the type, color, quality and skill of materials. 4) After these above procedures, all clothes fumigated to prevent the biodeterioration by using the mixed gas of methyl bromide and ethylene oxide as insecticide and fungicide. 5) Finally for the purpose to keep in a safety long-term condition, the treated clothes sealed with Biaxially Oriented Polyvinylacohol Film(BO-PVA film) and Helium, purity 99.999%, filled up in sealed BO-PVA film bag.

Plantae of the natural material has been broadly used on cloth dyeing by it's specific properties such as eco-friendly and innoxious. However dyeing with natural material on synthetic fiber is nearly impossible due to poor affinity between natural material and synthetic fiber. The method which is binding with micro-capsulized natural material to cloth, used in this study, has low change on quality by external influence. Also this method has high ability in spray effect by broken capsule which comes to pressure and friction when the treated cloth was dressed. And this method is applicable widely from natural fiber to synthetic fiber. The purpose of this study is to develop the multi-functional synthetic material with micro-capsulized Ginseng on PET. Moreover, it was driven by comparison of colormetric properties and fastness between regular dip-dyeing method and binding with micro-capsulized material method. Dyeability showed a little bit low exhaustion but the PET treated by micro-capsule was more or less better than the dip dyed PET. Through the SEM(Scanning Electron Microscope) of PET treated by micro-capsule, it has good residence of capsules even after 5 or 10 times washing. Wash and light fastness were revealed some different grades by each condition but showed high level, in most and the micro-capsulized PET was more improver than regular dip dyed PET.

Carbon cloth was impregnated into PTFE emulsion. PTFE is a fluoropolymer used as a coating material in various fields due to its hydrophobicity and excellent mechanical properties. In this study, PTFE emulsion was prepared different particle size of 5~500 nm and $3{\sim}5{\mu}m$. FE-SEM and FT-IR spectroscopy were used microscopic observation and investigation of chemical structure change after PTFE coating. Mass variations, gas permeability and water contact angles were analyzed to determine a GDL performance of PTFE coated carbon cloth. PTFE coated carbon cloth show different mass increase according as PTFE concentration and the number of coating times. Water contact angle of PTFE coated carbon cloth was not effected by size of PTFE particle and the number of coating time; meanwhile, gas permeability was rapidly changed at carbon cloth coated by emulsion with size of $3{\sim}5{\mu}m$ PTFE particle.

This paper presents a cloth simulation technique that implements plastic deformation. Plasticity is the property that material does not restore completely to the original state once deformed, in contrast to elasticity. We model cloth using a particle model, and posit two kinds of connections between particles, i.e. the sequential connections between immediate neighbors, and the interlaced connections between every other neighbors. The sequential connections represent the compression and tension of cloth, and the interlaced connections the bending in cloth. The sequential connections are modeled by elastic springs, and the interlaced connections by elastic or plastic spring depending on the amount of the current deformation of the connections. Our model is obtained by adding plastic springs to the existing elastic particle model of cloth. Using the new model, we have been able to simulate bending wrinkles, permanently deformed wrinkles, and small wrinkles widely distributed over cloth. When constructing elastic and plastic spring models for sequential and interlaced connections, we took pain to prevent the stiffness matrix of the whole cloth system from being indefinite, in order to help achieve physical stability of the cloth motion equation and to improve the effectiveness of the numerical method.

The purpose of this study was to examine how deconstruction, which currently had a great deal of influence on fashion, was actually accepted in view of fashion form or material. In order to track the tendency of deconstructional fashion, an attempt to find out what deconstructional methods were used in fashion design for each formative element was made by looking into earlier studies. Then an analysis was made over the recent fashion magazines. As a result of analyzing four fashion magazines, the most distinctive feature was found to be the use of seethrough cloth. In addition, unsymmetrical form also was immensely used. The next most frequently appeared form was layering, followed by slash or making a hole, lingerie look, padded cloth, indeterminate form, wrinkled cloth and patchworked cloth in the order named. The dominant layering style, the most widely used deconstructional fashion, was that inner cloth could be seen through outer seethrough cloth. The most frequently employed deconstructional cloth was seethrough cloth. Rather than complete seethrough cloth, the shape of lace, net or pattern was employed largely, in which the body could be partially hidden. The most largely used deconstructional method was a slash or making a hole. Most slashes appeared on the front part of the body, to which seethrough stuff was attached in many cases. Based on the above mentional finding. 10 kinds of deconstructional design were proposed for each method.

The rate of disposable diaper usage has been increased continuously from convenience of disposable diapers and increment of women's entry in workforce. However, a new perspective toward disposable diapers has been come to the fore in various sides like babies' health, environment, and cost. Furthermore, cloth diaper has started to attract more attention. Since parents and grandparents pay more attention to children as birth rate dropped, they tend to purchase expensive goods if the quality or design of the goods is worthy enough. Therefore, this study has the purpose in presenting the basic data for developing functional and pleasant cloth diaper with analyzing the consuming patterns (convergence in nature, health and technology) and cloth diaper characteristics. The research on the actual condition about children cloth diapers and environmental-friendly materials is as follows. Firstly, as a result of analyzing pros and cons about disposable diapers and cloth diapers, the cloth diapers are estimated to have better health, environment, and cost factors than disposable diapers, only excluding convenience. Secondly, as a result of examining patent registered diapers, the disposable diapers have been improved from shape-centered development to well-being material development, and the cloth diapers have mainly developed functional shape-centered. Thirdly, as a result of analyzing children's goods made with environmental-friendly materials, the children's clothes already use organics and natural resources like beans, bamboo trees, ginkgo, and chitosan. Recently, the diaper industry starts to pay attention to environmental-friendly because the skin ailment from environmental pollution has been an issue. To conclude, children's cloth diaper should be appropriate to their body shape and optimized to have convenient form and functional materials. If environmental-friendly materials are used, quality, functionality, various demands from customers and vitalization of goods industry will be all satisfied.
