Non-military researchers and civil manufacturers face several difficulties in the study of protective materials for chemical-biological defense. The performance of these materials cannot be estimated in non-governmental circles as the private use of chemical warfare agents (CWAs), such as GD (soman) and HD (mustard), by civilians is not permitted. The barrier properties of protective materials can be evaluated only in military laboratories, by the TOP 8-2-501 test method, using real CWAs. In this study, the permeation of CWA simulants such as dimethyl methyl phosphonate (DMMP), triethyl phosphate (TEP), and chloroethyl phenyl sulfide (CEPS) was investigated by the chemical permeation test method. Moreover, permeation of the CWA simulants through different samples of protective materials could be estimated by the proposed cumulative permeation measurements, using an absorbent tube.

DOI : 10.12772/TSE.2014.51.285
Oil adsorption capacities of reduced graphene oxide (RGO) and graphite oxide (GO) were investigated and compared with commercial graphite products. Adsorption capacities were determined by measuring the adsorbed amounts using a tea bag containing the adsorbent materials. RGO and GO showed higher adsorption capacities than other graphite adsorbents. This is attributed to the increase in the interlayer spacing and consequent development of mesopore structures, resulting in a decrease in the bulk density and increase in adsorption. Expanded graphite (EG) prepared in the laboratory showed a worm-like structure and good adsorption; however, commercial milled EG showed low adsorption capacities because the pores were crushed.

Alginates and chitosan are natural biopolymers with desirable biological properties. Sodium alginate/poly(ethylene oxide) (PEO) and chitosan/PEO blend films that are non-toxic, biodegradable, and biocompatible were prepared using the solvent casting method. The characteristics of the blend films with different blending ratios were investigated using a universal testing machine, differential scanning calorimeter, Fourier transform infrared spectrometer, contact angle apparatus (goniometer), and swelling test. The effect of the addition of a plasticizer on the swelling properties was evaluated for the chitosan/PEO blend films. With decreasing PEO content, the tensile strength of the blend film increased, but its strain decreased. The compatibility between sodium alginate or chitosan and PEO was confirmed, and the swelling properties could be controlled by the addition of a hydrophilic plasticizer. Therefore, the blending of natural polymers (with certain biological properties) with a synthetic polymer (PEO) could be a promising method to prepare biomedical materials with controllable properties.

Recently, nanomaterials obtained from biomass have gained attention due to their function and sustainability. Among bio-nanomaterials, cellulose nanowhisker (CNW) is one of the most potential materials for reinforcement of bioplastics due to its superior mechanical properties, biodegradability, and high aspect ratio. In the study, cellulose acetate composite was produced using CNW obtained under different conditions. There was a significant increase in the initial modulus of the composite with increasing CNW content, but there was no impact on the thermal stability.

An eco-friendly process for the fabrication of melt-fixed PET non-woven mats was developed to improve upon conventional production methods for floor or car mats by treating PET non-woven fabrics with polymer solutions of organic solvents. Thermoplastic powders with low melting points were dosed and distributed into PET non-woven fabrics with the application of high voltage, and then melt-fixed at an elevated temperature. Both unmodified polyethylene (PE) and poly(methacrylic acid) (PMA)-grafted PE (PE-g-PMA) with a grafted yield of 15.7% were used as base thermoplastic powders. Varying the amount of PE (modified or unmodified) powder, as well as the applied voltage, affected the mechanical properties of the melt-fixed mats. These effects were investigated by mechanical testing. Results showed that the tensile breaking stress of the melt-fixed mats increased, while the strain at break decreased, with increases in the amounts of PE or PE-g-PMA powder and the applied voltage. However, the mechanical properties of the mats were further enhanced when PE-g-PMA powder was used compared to unmodified PE powder. The application of high voltages during the powder treatment caused the hydrophilic polar groups in PE-g-PMA to distribute the grafted powder more evenly throughout the PET fabric. The resulting greater evenness in the distribution of PE-g-PMA made the grafted powder more effective in enhancing the mechanical properties of the melt-fixed mats more than the unmodified PE powder.
Study on High-speed Camera Observation of Electrospinning Behaviors

Electrospinning is a technology for producing nanofibers using high voltages. In this study, we investigated jet velocities and the corresponding electrospinning mechanisms using high-speed camera observation. Moving jets were observed at various exposure times for obtaining reliable velocity data. Significant differences were observed in the velocities according to the position between the tip and collector, as a function of applied voltages. However, the jet was found to consistently progress at 3-5 m/s near the collector. This suggests that the drawing effect of the electrospun fiber, induced by bending instability, occurs in a limited region.

The aim of this study was to measure the functional properties of a nanofiber web laminate, microporous film laminate, and nonporous coating fabric and then compare their performances as a breathable waterproof fabric. We focused on the performance of the nanofiber web laminate as a breathable waterproof fabric. A PU nanofiber web was prepared by electrospinning. The measured functional properties included the water vapor permeability, air permeability, waterproofness, adhesive strength, and water vapor resistance, as well as the property of a warm/cool feeling. The measurement results showed that the nanofiber web laminate fabric provided excellent moisture permeability as well as sufficient waterproofness and water vapor resistance in comparison to the microporous film laminate and nonporous coating fabric. We concluded that the performance of the nanofiber web laminate is sufficient for use as cloth in outdoor wear if an optimum electrospinning and lamination process is used in its production.

This study was aimed at identifying the color sensibility factors of cotton fabrics dyed with immature persimmon powder. The relationships of these factors with objective color characteristics, including tone, CIE color attributes, and mordanting, were determined and their prediction models, using the related objective parameters, were established. Fourteen dyed specimens, in a range of shades, were prepared as stimulus by dyeing cotton fabric with persimmon powder; some specimens were also subjected to iron-mordanting. Thirty-nine female college students evaluated these specimens based on 17 color image terms, using IRI color image scales. As a result, four color sensibility factors viz. clearness, vivid & dynamic, dignity, and natural & warmth were selected. Clearness, vivid & dynamic, and natural & warmth were more strongly perceived in non-mordanted fabric specimens. Pale increased the feeling of clearness while soft contributed to a stronger perception of natural & warmth. CIE
was positively related with clearness while
was a positive explainer for natural & warmth. All significant prediction models for the color sensibility factors were suggested for use in persimmon dyeing for textile and fashion products.

In this study, mechanical properties, such as tensile strength, tear strength, bursting strength, puncture strength, and transmissivity of nonwoven geotextiles were determined to evaluate their applicability as filter material in civil-engineering fields. For this purpose, spunbonded and needle punched nonwoven geotextiles were investigated according to their weight grade. The chemical resistance as a measure of the liquid resistance was analyzed on the basis of the strength retention with variable duration time under immersion condition. Finally, the long-term performance of these nonwoven geotextiles was reviewed by using Arrhenius' equation and the result were compared to consider their applicability as filter material.
