  • This study surveyed the preparation of 8oz coated fabric and the physical property of the coated fabric according to the treated condition for the sail yacht. And the coated fabrics were compared with the performance of overseas products for verification. Physical properties of the coated fabric treated with non-yellowing functional polyurethane resin were examined according to the treatment condition such as compression and ageing treatments. Finally, yellowing fastness to light for 60 hours was assessed. Considering the compression condition after coating, good physical property was obtained at $6kgf/cm^2$. Also, the performance of yellowing fastness was similar to performance of overseas goods.

  • Surface properties of the plasma treated fabric were changed while maintaining its bulk properties. Surface of plasma treated fabric take charge of enhanced adhesion by surface etching, surface activity. The water repellency coating Poly(Ethylene Terephthalate) fabric was treated with atmospheric pressure plasma using various parameters such as Argon gas, treatment time, processing power. Morphological changes by atmospheric pressure plasma treatment were observed using field emmission scanning electron microscopy(FE-SEM) and the zeta-potential measurement, contact angle measurement equipment. At the atmospheric pressure plasma treatment time of 150 sec, the power of 800W, the best wettability and peel strength were obtained. And we confirmed the possibility of industrial application by using atmospheric plasma system.

  • A solution containing 3-Mercaptopropyltr-imethoxysilane(MPTMS) was employed to modify surface of cotton fabrics with a silver colloid. Silver nanoparticles were applied on cotton fabrics via treatment with 3-MPTMS. The rate of silver nanoparticles on the fabric surface were measured with Energy Dispersive Spectroscopy(EDS). EDS results confirm the silver atom on the cotton surface.

  • In this study, TPU resin for coating was prepared by varying the mixing ratio of antistatic TPU and recycled TPU to manufacture permanent antistatic materials. The coated yarn was prepared by coating on the nylon yarn, and then the thermal, rheological, mechanical properties and antistatic properties were analyzed. In addition, antistatic properties and durability were confirmed after manufacturing UD fabrics using coated yarns. The mixing ratio of antistatic TPU and recycled TPU was most appropriate at 4:6, and the antistatic property had a surface resistance of 2.20 × 109 Ω and a static charge of 398 V. In the coating process, the coating speed was most appropriate at 0.21 m/s, and the surface resistance of the UD fabric manufactured with the coated yarn manufactured under this condition was 6.80 × 109 Ω and the static charge was 484 V. The UD fabric had a surface resistance of 7.21 × 109 Ω and a static charge of 517 V after washing 10 times, and it was confirmed that the permanent antistatic property was excellent.

  • In this paper, we report and discuss the semi-permanently hydrophilic (SPH) treatment of polyester fabric using plasma polymerization and oxidation based on atmospheric pressure dielectric barrier discharge (APDBD) technology. SiOxCy(-H) was coated on polyester fabric using Hexamethylcyclotrisiloxane (HMCTSO) as a precursor, and then plasma oxidation was performed to change the upper layer of the thin film to SiO2-like. The degradation of hydrophilicity of the SPH polyester fabrics was evaluated by water contact angle (WCA) and wicking time after repeated washing. The surface morphology of the coated yarns was observed with scanning electron microscopy, and the presence of the coating layer was confirmed by measuring the Si peak using energy dispersive x-ray spectroscopy. The WCA of the SPH polyester fabric increased to 50 degrees after 30 washes, but it was still hydrophilic compared to the untreated fabric. The decrease in hydrophilicity of the SPH fabric was due to peeling of the SiOxCy(-H) thin film coated on polyester yarns.

  • The merits of activated carbon for removal of organic compounds have been well known in the various industrial fields. Fixing methods with activated carbon in the non-woven fabric have the advantages of fast adsorption and ease of handling when compared with bonding and coating methods. In this study, we have examined deodorization of non-woven fabrics fixed with activated carbon. We have been tested the deodorization of various kinds activated carbon and non-woven fabric structures. The effective mixing ratio of activated carbon was 5% on the weight of fabrics, which are closely related to the fabric structure. The activated carbon with higher mesh size show the better deodorization effect.

  • In this study, the molten metal protective performance of various molten metal protective clothing materials such as herringbone twill laminated aluminium foils, oxydized-polyacrylonitrile laminated with aluminium deposited polyethylene terephthalate films, twill fabric laminated with aluminium deposited polyethylene terephthalate films and nonwoven laminated with aluminum deposited polyethylene terephthalate films, were evaluated according to modified EN ISO 9185. The results showed that the molten metal protective performance of tested samples improved with the increase in fabric structure density, weight and thickness. In addition the effect of the thickness of aluminum foil on the molten metal protective performance is not significant. It was found the fabric is more important in the molten metal splash protective clothing.

  • As a reinforced fabric, asbestos has been utilized as a fire-resistant material as it has a superior flexural stiffness and heat resistance up to $1500^{\circ}C$. However, due to its harmfulness, its use has been prohibited recently and the even the installed asbestos materials are being repaired or supplemented if there is a concern about flying. Asbestos is mainly used for construction panels as a reinforced fabric and coating materials to ensure the fire-resistance of steel frames. Asbestos was used as fire-resistant materials for steel frames until 1991 and then prohibited as Act on Industrial Safety and Health limits the concentration of asbestos in the air. Classified as a designated waste according to Act on Waste Control, asbestos must be buried if there is no possibility of flying (panel-type materials) or cement-solidified and then buried if there is a possibility of flying (spray coating material) In general, it is required that a new waste landfill include a certain landfill facility for designated waste, but in reality there is an absolute storage of landfill facilities for designated waste as they only install facilities of the size required by the regulations. This could result in the 2nd environmental pollution as they cannot process asbestos wastes which will be generated in large volume in the future. This study explores a method that melts asbestos wastes at $700^{\circ}C$ rather than cement-solidifying the waste asbestos from construction sites, especially asbestos-containing spray coating. The study results showed that there was no change in the composition and shape even though asbestos wastes was melted at $1300^{\circ}C$, but there was a change for the specimen which was process in advance for low temperature melting and then melt at $900^{\circ}C$.

  • Experiment I and II had done to develop the solar heat proof hat for field work in the summer. In the experiment I physical characteristics of several fabrics was tested to determine which one Is proper to make the solar heat proof hat. On the base of above results in the experiment II three improved solar heat proof hat was deviced and tested solar heat proof effect and compared the existing summer working hat by wearing trials in the environmental chamber. The results obtained were as follows. 1. In the view of the physical characteristics of six fabrics (Blue T/C, White poplin, Vapor transfer silver coating nylon taffeta, No vapor trans(or silver coating nylon taffeta, Aluminum coating T/C, Microporous fabric), the light color T/C and no vapor transfer silver coating nylon ta(feta is proper to make improved solar heat proof working hat. 2. Three improved hats that are made of white T/C, grey T/C and no vapor transfer silver coating nylon taffeta have more solar heat proof effect than the existing summer working hat. 3. Among the three improved hats, the improved hat that is made of no vapor transfer silver coating nylon taffeta is most effective to proof the solar heat.
