The objective of this study was to investigate electrical conductivity of fabrics from polyester (PET) and Nylon (N) containing polyurethane (PU), with silver paste patterns screen-stenciled in three directions. The PET/PU and N/PU fabrics knitted or woven were uniaxially strain-recovered up to 22.5% in three times when each change in electrical resistance was simultaneously measured. This study established four variables that complexly affected electrical conductivity of these specimens; fabric structures, components, cover factors, and the percolation of silver particles. The woven or knitted fabric structures did not distinctively cause the changes in electrical resistance, however, the woven fabrics with the diagonal patterns showed their relatively high electrical resistance. The PET/PU fabrics with increasing the PET proportion generally presented the opposite propensity to its electrical conductivity. The changes in electric resistance of the PET/PU 85/15 2/1 twill and double plain fabrics instantaneously responded to the rate of elongation. The PET/PU group exhibited a reverse correlation between its cover factor and electrical resistivity. The highest electrical conductivity of the PET/PU 95/5 interlock fabric, with very few fluctuations, was attributed to the deep percolation of the silver particles that bridged the gaps between one loop and another. On the other hand, the occurrence of the silver cracks along with the elongated direction led to the immeasurably high change in electrical resistance as the strain increased.

The purpose of this study is to analyze the dyeability of polyester(PET) fabric by thermal bonding with low melting component of bicomponent fiber and to describe the change of physical properties of thermal bonded PET fabrics. The PET fabrics were prepared with regular PET fiber as warp and bicomponent fiber as weft. The bicomponent fiber of sheath-core type was composed with a regular PET core and low melting PET sheath. The thermal bonding of PET fabric was carried out in pin tenter($195^{\circ}C$) for 60 seconds. In this study, we investigated the dye ability and fastness of the dyed PET fabric. Dye ability of E-type dyestuff is higher than S-type dyestuff. In the case of E- type dyestuff, the saturated dyeing time was 10minutes at $130^{\circ}C$. The washing fastness and light fastness were excellent as 4-5grade.

The purpose of this study is to research and develop the concepts and functions of the Metabus dog fashion show. Currently, as the pet-related industry grows rapidly, the pet fashion industry is also naturally growing. However, unlike the fast-growing fashion industry, it was not enough to meet the needs of dog owners. Therefore, this study attempted to develop a metaverse dog fashion show by supplementing the problems that arise when purchasing existing pet clothes through metaverse. As a research method, first, a survey was conducted on the rise in the actual pet-related industry and the social trends of metaverse and virtual fashion shows. Second, the existing dog clothing purchase characteristics were examined through user demand analysis, and user needs were derived. Third, the appropriate form of content was established, and a new content consumption environment called metaverse was analyzed and derived. Finally, functions were derived and developed to give users satisfaction. In the future, it is necessary to study a clear payment system in connection with the actual dog clothing business based on this.

The purpose of this study is to prepare the hardness of polyester(PET) fabric by thermal bonding with low melting component of bicomponent fiber and to describe the change of physical properties of thermal bonded PET fabrics. The PET fabrics were prepared with regular PET fiber as warp and bicomponent fiber as weft. The bicomponent fiber of sheath-core type were composed with a regular PET core and low melting PET sheath. The thermal bonding of PET fabric was carried out in pin tenter from 120 to $195^{\circ}C$ temperature range for 60 seconds. In this study, we investigated the physical properties and melting behavior of PET fiber and the effect of the temperature of the pin tenter on the thermal bonding, mechanical properties. Melting peak of warp showed the thermal behavior of general PET fiber. However, melting peak of weft fiber(bicomponent fiber) showed the double melting peak. The thermal bonding of the PET fabric formed at about temperature of lower melting peak. The optimum thermal bonding conditions for PET fabrics was applied at $190{\sim}195^{\circ}C$ for 60seconds by pin tenter. On the other hand, the tensile strength of the PET fabric decreased with an increasing temperature of thermal bonding.

This paper investigated wear comfort property of heat storage knitted fabrics for high emotional garment. For this purpose, ZrC imbedded PET knitted fabric was prepared and various physical properties such as thermal, wicking and drying characteristics were measured. In addition, far-infrared emission characteristics of ZrC imbedded PET was analysed and tactile hand property and dye affinity of ZrC imbedded knitted fabric were also studied in comparison with regular and other commercial heat storage PET knitted fabrics. It was observed that Zr imbedded amount in the yarn was 19.29% by ingredient analysis and far-infrared emission energy was $3.65{\times}10^2W/m^2$, emissivity was 0.906 at the range of wavelength $6{\sim}20{\mu}m$. It was found that maximum heat flow (Qmax) of ZrC imbedded PET knitted fabric was lower than that of regular PET one and warmth keepability rate was higher than that of regular PET one, which means ZrC imbedded PET have heat storage property. Drying property of ZrC imbedded knitted fabric was better than that of regular PET one due to heat by far-infrared emitted from ZrC in the core of filament. It revealed that wicking property of the ZrC imbedded fabric was not influenced by far-infrared emission, but affected by fibre physical properties. Tactile hand property of ZrC imbedded knitted fabric was not influenced by imbedding ZrC in the filament but affected preferably by structure of knitted fabric. Dye affinity of ZrC imbedded PET knitted fabric was less influenced by dyeing temperature and time than regular PET knitted one.

Superior hydrophilic properties will allow varieties of polyester(PET) fiber materials, fabrics and industrial materials a broader scope of use. The purpose of this study was to investigate the effect of water-absorbent softener treatment on the end-use properties and the hand of polyester knitted fabrics. Two different fabrics were knitted for the summer ladies' outwear; PET jersey and PET mesh. Variables were softner treatment and stitch type(jersey and mesh). Mechanical properties of the fabric samples were measured by KES-FB system. From these, primary hand values(HV) were evaluated by the conversion equation (KW-403-KTU) and the total hand value(T.H.V.) was calculated according to the KN-304 Summer. Both water-absorbent softner treatment and stitch types affected mechanical properties and hand values of PET fabrics. Mesh were thicker than single jersey stitch. As they became thicker, tensile, shear, and compressional energy increased. It appeared that coefficient of friction of mesh stitch was larger than that of single jersey stitch. The coefficient of friction and the mean deviation of surface roughness were decreased by softener treatment. After softner treatment KOSHI and SHARI of the both PET jersey and PET mesh decreased. However, FUKURAMI values of PET jersey increased and that of PET mesh decreased. The T.H.V. of the treated PET jersey was lower than that of the untreated one, while the T.H.V. of the treated PET mesh was higher than that of the untreated one. Overall T.H.V. of the single jersey was better than that of the mesh before and after softner treatment.

This research was made to manufacture the fabric for interior uses by spinning a low melting mono 4 denier PET staple fiber with a soluble 1.4 denier fine PET fiber. The blended yarn has a thickness ranging from 10's to 14's, and the soluble PET fine fiber was dissolved to make a pore in the polymer. Thereby a snap property was decreased and a resilience property was improved to be suitable for a functional synthetic leather. In order to attain the optimum condition, a mechanical property according to fineness, and mixing ratio of low melting polymer, warp density, weft density and blending ratio, and a heat contraction ratio according to blending ratio were experimented. The warp density, 220 T/inch of fine denier PET and the weft density, 64 T/inch of thick denier PET were generated to 4/4 both twill weave fabric having constant tensile property and thickness.

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.
