Recently, clothing products equipped with information devices to provide various types of information to the person wearing them have been commercialized. In the case of clothes using IT devices, a general method is to manufacture a circuit to transmit input signals and a connector to connect communication devices to additional devices, that are manufactured separately from the clothes and attached. These designs includes the circuit between the outer garments and lining. Therefore, they are applied to jackets with certain volume limitations. In addition, it is also troublesome that a separate process is needed. On the other hand, this problem can be solved by connections with an IT device via the embroidery of conducting yarn. Accordingly, in this study, sewing and embroidery to provide a signal transfer route for sound source data and a connection between information and communication devices and input/output devices conveniently were examined. An electrically conductiing thread made by coating with silver on 200 denier and 48 filament nylon thread was used as a sewing thread. The Vrms(voltage-root-mean-square) displaying the average value of the sound source through 2 types of stitching, 70 cm in length, on 100% nylon as the sewing thread was measured to determine the amount of sound and data loss. Based on the data, the stitch, 70 cm in length, sewed overlapping 5 times, and the end point was connected to a snap and applied to the cloth to attach to a mp3. The use of conductive yarn as embroidery yarn, can allow the transfer of sound sources without limitations to the clothing design. Accordingly an expansion of applications of smart wear is expected.

The effects of the tentering-extension rates and repeated washing on the mechanical properties and hand values of cotton/ spandex twill were examined. A 3% spandex containing cotton twill was treated by tenter extension at different rates of 0%, 5%, 10% and 15%. The processed fabric with a 0% extension rate was also dyed using a reactive dye. The KES-FB system was utilized to measure the mechanical properties of the twill, and the basic and total hand values were determined using a KN-201-MDY and KN-301-WINTER, respectively. The fabrics treated with greater tentering extension and dried in a clothes tumble dryer showed lower bending and shear properties, and became softer and smoother. The greatest change in the mechanical properties and hand values occurred after the first wash, but the differences in the washed and unwashed state decreased with increasing number of wash cycles. These results show that cotton/spandex twill should be extended 5% during tentering to yield less deterioration of the T.H.V., and be dried in a clothes tumble dryer to maintain a soft and smooth hand without affecting the shrinkage and elasticity.

The effect of solvents on the surface morphology and mechanical properties of poly(vinyl acetate) nanofibrous nonwoven via electrospinning was investigated. The fiber diameters decreased with increasing boiling point of the solvents. Among the solvents used in this study, DMF was the best solvent that produced PVAc fibers with the thinnest diameter of ca
. Such a result can be explained by considering the high boiling point of a solvent, allowing sufficient time for a smaller segment of a charged jet during its flight to the collector.

Textile Science and Engineering, volume 47, issue 4, 2010, Pages 253~260
Hansan ramie fibers were irradiated with an electron beam to improve the interfacial bonding in the manufacture of composites. The effect of electron beam irradiation was examined by SEM, chemical component analysis and the mechanical properties. The impurities on the surface of ramie and lignin were removed by electron beam irradiation, which increased the tensile strength of the ramie fibers. However, the excessive electron beam energy caused the degradation of ramie fibers, due probably to the reduced
-cellulose. The reduction of
-cellulose indicates the degradation of the cellulose chain, which usually leads to a decrease in fiber strength.

Textile Science and Engineering, volume 47, issue 4, 2010, Pages 261~265
The properties of polypropylene (PP)/multi-walled carbon nanotubes (MWNTs) composite were examined. MWNTs were wrapped with polypropylene-graft-maleic anhydride (PP-g-MA) followed by functionalization with hydrogen peroxide (
) for good dispersion in a PP matrix. The
-treated MWNTs were characterized by Raman spectroscopy (RAMAN) and Elemental analysis (EA). These results suggest that hydroxyl groups were introduced to the nanotube surface. The homogeneously dispersed PP/MWNT nanocomposites were prepared by melt mixing using a twin-screw extruder. The SEM images of the neat MWNTs and functionalized MWNTs showed that the functionalized MWNTs had been dispersed well in the matrix whereas the neat MWNTs (N-MWNTs) aggregated. Thermal analysis and the stress-strain data showed that the well dispersed MWNTs in the PP matrix greatly enhanced the mechanical and thermal properties of polypropylene.

Bacterial cellulose is formed by microbial Gluconacetobacter xylinus, which produces a cellulose pellicle in its culture medium. The bacterium Gluconacetobacter sp. V6 was cultured in three types of media using an agitation method: a standard Hestrin-Schramm medium and a medium modified with either glycerol or molasses as the carbon sources. The structural properties of the cultured bacterial cellulose, such as crystallinity, viscosity and mechanical properties, were examined. Cell growth was excellent in the agitated culture with the molasses medium, and the cellulose yield was excellent in the agitated culture with the glycerol medium. The agitated culture with the molasses medium resulted in increased cell growth and cellulose yield, as well as improved mechanical properties of cellulose compared to the static culture with the molasses medium.

The physical and functional properties of various woven fabrics with Hanji/cotton and Hanji/silk were examined. The tensile linearity, tensile resilience, bending rigidity, bending hysteresis and shearing stiffness increased with increasing Hanji yarn content. On the other hand, the compression linearity and coefficient of friction decreased with increasing Hanji yarn content. Grade 4-5 or 5 on the abrasion resistance and pilling test were obtained in six samples. The drape test showed that the flexibility of the samples was affected by the Hanji yarn content. Moreover, the shape of the samples showed anisotropy with increasing Hanji yarn content.

The bulk polymerization and thermal properties of biodegradable poly(1,4-dioxan-2-one)[poly(p-dioxanone), PPDO] were investigated. The in vitro hydrolytic degradation behavior of PPDO monofilament sutures were also examined over a 16 week period at
. The degree of PPDO polymerization decreased with increasing content of the initiator, lauryl alcohol[
]. The thermal stability of PPDO was inversely proportional to the content of the catalyst, Sn(II) ethylhexanoate[
]. Considering the efficiency of polymerization and the thermal stability of PPDO, the proper contents of Lauryl alcohol as an initiator and ethylhexanoate as a catalyst were 1600~1900 ppm and 20~30 ppm, respectively. Based on the determination of the half crystallization time, the crystallization speeds of dyed PPDO chip and monofilament suture were higher than those of undyed PPDO chip and monofilament suture. The maximum rates of crystallization of the dyed and undyed samples were observed at around
, respectively. At the beginning of the in vitro time, the tensile strength of the PPDO monofilament suture decreased slowly but decreased considerably after a certain period, indicating that the degradation proceeded in two steps, the first occurring in the amorphous regions and the second in the crystalline regions. The average molecular weight of the PPDO monofilament suture decreased continuously from the beginning of the in vitro time, due to the random nature of the degradation process. The breaking strength retention (BSR) and molecular weight of the PPDO monofilament suture showed a quadratic function relationship.

Automotive textiles are the most valuable world market for technical textiles, and environmental requirements are putting pressure on the automotive industry to reduce the fuel consumption and
emissions from vehicles. The purpose of this study is to develop a lightweight and eco-friendly cushioning material to substitute for PU foam in automotive seat. To recycle and reduce the weight of the vehicle, PET hollow fiber was used to manufacture the 3D spacer fabric structures. The characteristics required for the automotive seat cushion were evaluated and the significant changes with the structural components were analyzed. The results show that the hardness and compressional properties are positively affected with the thickness of spacer fabrics though air and water vapor permeability decreased slightly.

The rheological behavior of mesophase and isotropic pitch blends were examined using capillary and coneplate viscometers to determine the spinnability. The mesophase synthesized from naphthalene and coal tar pitch modified with benzoquinone were used. The individual component of the mesophase pitch or the isotropic phase pitch showed excellent spinnability but the spinnability of the blends decreased as the composition approached 50 wt.%. The variations of the spinnability were explained based on the mechanisms of capillary break-up and cohesive brittle fracture. The fracture of the spin line was caused mainly by capillary break-up originating from the high interfacial tension between the two separated phases; the behavior was more severe in the lower shear rate region, i.e. the elasticity dominant area. The spinnability of the two phase blends could be improved by maintaining the melts under the viscosity dominant condition by adjusting the shear rate and temperature.
