Rod-like hydroxyapatites (HAs) were successfully fabricated with
, and polyvinylpyrrolidone (PVP) as a stabilizer. FT-IR was used to identify rod-like HA and to observe the functional groups on the surface of HA. We conducted the turbiscan test to confirm the effects of the HA ratio on the dispersion stability in the chloroform/acetone mixture. A 3D scaffold for bone tissue regeneration was produced by electrospinning poly(L-lactide) (PLLA) with 2, 5, and 10 wt% of rod-like HAs. SEM, TEM, and XRD showed that rod-like HAs were well-embedded into the electrospun PLLA nanofibers and the mechanical properties of PLLA and PLLA/HA nanofibers were measured by UTM. Pure PLLA nanofibers had higher tensile strength than PLLA/HA nanofibers. Furthermore, 2 and 5 wt% of HAs-incorporated PLLA nanofibers showed increased Young`s modulus compared to pure PLLA nanofibers because of the hardness of HA and the strong interaction between PLLA and HA by hydrogen bonds.

For the optimum performance of compression sportswear, tensile properties of base tricot and power film should be understood in the viewpoint regarding the use condition. However, it is difficult to predict the tensile properties of film-welded tricot, solely from the tensile information of the single layer of tricot or power film itself, especially when the direction of the power film does not follow the wale or course direction of the tricot, which often occurs in the actual design of performance sportswear. In this study, changes in the tensile properties of tricot, power film and film-welded tricot were investigated as the angle of tensile axis and the direction of welding varies from
. Stress, initial modulus, and tensile energy were obtained up to 33~50% of the extension level, which is often observed in actual use. Results indicate that the area of power film matched to the tensile axis and width of power exertion is the key factor of tensile properties explaining stress, initial modulus and energy required during extension. Moreover, the results obtained in this study can be utilized in the arrangement of pattern piece for tricot and the positioning of power film to achieve the right support and extension level during body movement.

In order to investigate the contraction variation of an N/P (nylon/polyester) microfiber woven fabric wiper, optimal mixing ratio of surfactants and solvents were investigated. Four kinds of solvents including four anionic surfactants and seven nonionic surfactants were assessed for the best contraction characteristics of the fabrics. Emulsifying capacity, foaming capacity, and contraction power were measured and the optimal solution mixing ratio was selected. When the optimal mixing ratio of 36:54:60:850 was used in regards to aryl ethoxylate sulfate, EO/PO copolymer, methoxy propanol and benzyl alcohol, the contraction power of the fabric was obtained in terms of emulsifying capacity, foaming property and recyclability.

In this work, the annealing characteristics of chemically recycled cation dyeable poly(ethylene terephthalate) (CD PET) fibers were investigated and compared with those of regular CD PET. Recycled CD PET was polymerized using chemically recycled monomers of dimethyl terephthalate (DMT), which is chemically recycled from final products such as bottles and fibers. Mechanical properties and structural changes were studied for different annealing temperatures and times. The tensile properties and structural changes of recycled CD PET show similar behavior to those of regular CD PET. The crystal structure of chemically recycled CD PET developed well with increasing annealing temperature and time. At annealing temperature of
, thermal shrinkage decreases to below 2% even after 10 min of annealing.

Phase change materials based on UHMWPE blended with n-octadecane were studied in this paper. In addition, this paper reviews recent studies on the preparation of shape stabilized phase change materials (SSPCM), such as SSPCM from UHMWPE and n-octadecane, their basic properties and possible applications to latent heat storage. The preparation methods used were the melting methods. Shape stabilized PCM (SSPCM) prepared for FT-IR spectroscopy, SEM, DSC, XRD, and ARES results of the analysis for shape stability to improve heat capacity were identified. The optimum compounding conditions included a content of 40% n-octadecane. The SSPCM 40% demonstrated less deterioration of physical property and effective thermal property compared with other conditions. As a result, these SSPCMs could be said to be acceptable heat storage & release materials for various products.

The effects of annealing on the fine structure and moisture regain of nylon 4 copolymer films were investigated in terms of the content of nylon 4. Nylon 6-ran-nylon 4 (50/50), (30/70), and (0/100) films were prepared using melt pressing and solution casting methods, respectively. The (N6-ran-N4) copolymer films were annealed in a silicon oil bath at 50, 75, 100, 125 and
, and the properties of resultant film were examined by WAXD, DSC, DMTA and moisture regain. The crystal structure in (N6-ran-N4)(50/50) and (30/70) films with increasing annealing temperature was very similar to the gamma phase of nylon 6. The thermal property of (N6-ran-N4)(50/50) and (30/70) films annealed under high temperature exhibit an increase in melting temperature and enthlapy. The result of the tan
behavior of (N6-ran-N4)(0/100) film was confirmed to the appearance of two
transition peaks. The moisture regain of (N6-ran-N4) copolymer films, except in the case of (N6-ranN4)(30/70) films, decreased when the annealing temperature was increased.

Meta-aramid nanofibers were prepared by the electrospinning process. In this study, electrospun meta-aramid nanofiber webs were prepared with various velocity ratios of a collector drum, the fiber diameter and thickness of electrospun nanofiber webs, and then compared with values of tensile properties and breathable water-resistance. The meta-aramid nanofiber webs were analyzed by field-emission scanning electron microscopy, a tensile tester, water vapor permeability, an X-ray diffractometer and thermogravimetric analysis. The diameter of meta-aramid nanofibers ranging from 165 to 252 nm was obtained by electospinning. The tenacity, young`s modulus and crystallinity of meta-aramid webs were decreased by increasing the diameter of meta-aramid nanofibers, however, water vapor permeability increased. It was confirmed that the breathable water-resistance of meta-aramid nanofiber webs were similar to that of chemical treated PTFE film.

DOI : 10.12772/TSE.2012.49.4.250
In this study, the instabilities of electrospinning were observed and evaluated by measuring the drop area, the current, and the electrical force using PVAc and PVA. Those values were measured simultaneously during electrospinning and the instabilities were analyzed as a function of time. The electrospinning was carried out by changing the voltages and the feed rates. The results suggest that different electrospinning conditions such as voltage, polymer, and flow rate caused different behaviors of instabilities, current and electric force, however, all the used methods were effective for studying the instabilities in electrospinning.

We have manufactured polylactide (PLA) nanocomposites reinforced with layered silicates by the melt compounding method and have investigated their structure, thermal stability under oxygen or nitrogen atmosphere, and temperature-dependent mechanical modulus by adopting XRD, SEM, TGA, and DMA. Octadecylammonium-modified montmorillonite (organo-MMT) is used as an organically modified layered silicate and, for comparison, sodium montmorillonite (Na-MMT) is adopted as a purely inorganic layered silicate. X-ray diffraction patterns and SEM images confirm that the organo-MMT is intercalated and dispersed homogenously in the PLA matrix, whereas Na-MMT remains unchanged by forming agglomerated domains in the matrix. Unlike the PLA/Na-MMT nanocomposites, the thermal stability of PLA/organo-MMT nanocomposites is found to be substantially improved with the increment of organo-MMT content, especially under oxygen gas atmosphere. In addition, the mechanical modulus of PLA/organo-MMT nanocomposites in the glassy state are highly improved.

An air intake duct is an automotive part for transferring outside air to the internal combustion engine where the air and fuel are mixed and consumed. While this part has been primarily made of engineering plastics, many manufacturers are attempting to apply textile nonwovens due to their superior sound absorbing performance and lightweight characteristics. In this paper, we studied the manufacturing process of needle punched nonwoven fabric and analyzed various properties in order to investigate the applicability of textile nonwoven as a material for automobile air intake ducts. The nonwoven web was prepared by opening, mixing and carding PET staple fibers and binder fibers. The web was physically bonded by the needle punching process. In addition, we applied heated air through the nonwoven web to improve the mechanical properties of the needle punched nonwoven fabrics by the thermal bonding of interlocking constituent fibers. The results of the tensile test of the nonwoven demonstrated that the hot air treatment to the needle punched nonwoven decreased the elongation of nonwoven, which significantly affects the processability of the air duct production process. Also, the porous structure of the nonwoven improved the sound absorbtion property compared to normal PP plastic. Therefore, the air intake duct made of PET needle punched nonwoven could contribute to decreasing the noise level inside automobiles.
