Polypropylene (PP) is one of the most widely used materials because of its rational mechanical characteristics. However, the application of PP is significantly limited and infrequent due to its easy combustion and dripping properties. To improve the thermal versatilities of PP, halogen-containing compounds, alone or in conjunction with antimony trioxide, have frequently been used in the flame retarding PPs. Halogen-containing flame retarding agents, however, are supposed to produce corrosiveness, smoke emissions, and toxicity which are combustion products. In this study, red phosphorous, metal oxides, and zinc borate were used as flame retarding agents for PP. The thermal properties of injection-molded PP specimens were characterized by thermogravimetric analysis, differential scanning calorimetry analysis, and UL94 flame retardation tests. Results showed that increased char formation on the surface can confirm flame retardation of the UL94 V0 grade of PP.
The Effects of Surface Morphology of Poly(ethylene terephthalate) Film on Detergency of Particulate Soil (II) -The Adsorption of Surfactant and Interfacial Electrical Phenomena-
Kang, In-Sook ;
Textile Science and Engineering, volume 48, issue 5, 2011, Pages 280~288
This study is the preliminary part in investigating the influence of surface characteristics of substrates on detergency of particulate soil. The surface of PET film was modified with NaOH and DMF for different time. Generally, the adsorption of surfactants of the film treated with NaOH and DMF was relatively higher and lower than those of non-treated film, respectively. And the adsorption of surfactant was increased with an increasing concentration of the surfactant regardless of its treated condition. But the effect of ionic strength on the adsorption of surfactant varied with the treated condition. The
-potential of film and the interaction energy between
particle and a PET film treated with NaOH was largely higher than the original film, but those treated with DMF was lower. The adsorption of surfactants to the film and the
-potential of film were related more with contact angle and surface energies than with the surface roughness and surface area. A coefficient of the correlation between adsorption of surfactant to substrate and the
-potential of film was over 0.9.

The failure modes and mechanisms of the interior parts of automobiles by cosmetics were studied under accelerated failing conditions of an actual working environment. The covering films for the interior parts were doped with three types of sunblocks and their ingredients. The failure of the doped films was accelerated by increasing the test temperature. The typical failure modes observed in the study were the swelling and cracking of the film's surface by the decomposition and the micro-structural changes of the films. This study can help the automobile company to design a plastic interior covering film for better reliability.
Electromagnetic Shielding Effectiveness of the Stainless Steel Hybrid Jacquard Fabrics
Lee, Jung-Soon ;
Textile Science and Engineering, volume 48, issue 5, 2011, Pages 297~304
This study investigated the electromagnetic shielding effectiveness, UV protection, and thermal storage of stainless steel hybrid jacquard fabrics. Eight stainless steel hybrid jacquard fabrics were woven with two kinds of warp yarns (nylon and rayon) and a weft yarn blended with various amounts (0, 7, 14, 21%) of stainless steel yarn. The results showed that the stainless steel hybrid jacquard fabrics provided effective electromagnetic shielding. While the electromagnetic shielding effectiveness of stainless steel hybrid jacquard fabrics was obviously frequency dependent, the overall electromagnetic shielding effectiveness increased as the proportion of stainless steel yarn increased. However, the 7% stainless steel hybrid jacquard fabric provided electromagnetic shielding effectiveness values over 10 dB in the frequency range of 350- 1.2 GHz. In short, the 7% stainless steel hybrid fabric is suitable for use in fashion fabrics while providing effective electromagnetic shielding. By adding stainless steel yarn, UV protection was increased but thermal storage suffered.

Among textile machinery, a winding machine is a kind of preparatory machine and refers to the machine that winds the bobbin with yarn in a uniform density, length and size for the processes required to shuttle less looms, knitting machines, embroidery and sewing machines, etc. From grey yarn to weaving, yarn is wound many times in various ways, and the most important factor in the process of winding is maintaining uniform yarn tension through technology. Therefore, in this study, we researched the high-precision techniques of measuring yarn length very precisely and the yarn winding tension capable of maintaining uniform yarn tension during the winding process by the winding machine. In addition, we configured and verified the high-precision yarn length measurement and the yarn winding tension control system through experimental devices. As a result, we verified the stable control result value of a 50% reduction in average tension for the case of the active disturbance rejection control (ADRC) yarn winding tension control system, and also verified the result that there is about an 80% reduction in yarn length errors after winding 10,000m by the high-precision measurements of yarn length.
Polyelectrolytic Behaviors of Carboxylated MWNT
Eun, Hee-Chun ; Cho, A-Ra ; Kwark, Young-Je ;
Textile Science and Engineering, volume 48, issue 5, 2011, Pages 310~314
Anionically charged MWNT with anionic carboxylic acid groups were mixed with cationic organic polymers, such as poly(allyamine hydrochloride) (PAH) and, poly(diallyldimethyl-ammonium chloride) (PDDA) to form polyelectrolyte complexes by coulombic interaction. The complexation behavior of the MWNT was affected by pH when mixed with PAH containing weak basic amine groups. By increasing the content of cationic polymer, the zeta potential of MWNT was increased from a negative values to a positive ones. With higher pH, the isoelectric point of anionic MWNT and cationic PAH increased and the saturated zeta potential value with high PAH content due to the less ionized MWNT and more ionized PAH. On the other hand, strong basic PDDA was less affected by changing pH and showed a similar isoelectric point and saturated zeta potential value with high PAH content. The complexation changed the dispersibility of MWNT in water, with the result that the MWNT was precipitated around the isoelectric point but then re-dispersed with higher cationic polymer content. HR-TEM images confirmed that excess PAH completely covered the MWNT.

The alkaline dissolution behavior and dyeing properties of acid dyes and reactive dyes on sea-island type ultrafine nylon fiber were investigated in this study. The alkaline dissolution behavior was very dependent on the concentration of NaOH and temperature, the most appropriate condition was to treat the fabric with 10 g/l NaOH for 30 min at
. The dye uptakes of the ultrafine nylon and regular nylon fiber decreased as the dyebath pH increased. Although the exhaustion percentages of the ultrafine nylon fiber were higher than those of the regular nylon at all pHs, the color strength of the dyed ultrafine fabrics were weaker due to the increased surface area per unit mass. The washing fastness of the ultrafine nylon fibers dyed with the reactive dyes was found to be excellent.

Dynamics of the bundle thickness in a friction yarn formation process was ascertained experimentally from the view point of the thickness of in-process bundle and output bundle. By changing the thickness of input fleece the thickness distribution of the in-process bundle on the friction drum and the irregularity of the output bundle in a steady state were measured. The experimental results were then compared with the simulation results derived on the basis of the dynamic model, while a step signal and a sinusoidal signal were applied. Experimental results turned out to be in a good agreement with the simulation result, which indicates that the theoretical model describes the dynamics of the frictional bundling process very good. The cross-sectional area of the in-process bundle increased linearly to the drum position in response to a step change in the input fleece thickness, which indicates that the friction bundling process can be though of as an integrating system with an interval. The periodic change in the input fleece thickness yielded also a good correspondence of the experimental results with those from the simulation. However, the thickness behavior of the output friction yarn for the periodic change in input fleece thickness demonstrated the dependency on the take-up speed of the output bundle.
