Development of Virtual Prototype of High Performance Needle and Guide Driving Unit for Domestic Raschel Machines
Song, Suk ; Kim, Young-Gyu ;
Textile Science and Engineering, volume 42, issue 2, 2005, Pages 65~70
We have designed a new driving mechanism of the raschel machine for industrial fabrics using the eccentric earn. Domestic raschel machines for industrial fabrics have low productivity and high level of noise and vibration because it uses the pot earn in the main driving mechanism. The goal of this research is to reduce the noise and vibration, and to enhance the productivity of the domestic raschel machine. Three dimensional modeling of the parts was carried out by using MDT (mechanical desktop), and kinematic analysis has been implemented to design the new needle driving and the guide driving mechanisms using the Visual Nastran program. To estimate the safety of the principal parts of the mechanisms, finite element analysis (FEA) has been conducted by using Visual Nastran program. As the result of FEA, the newly designed needle driving and guide driving units is estimated safe under actual driving. Consequently, we have developed a virtual prototype of the needle driving and guide driving units of the raschel machine for industrial fabrics which increase the productivity remarkably and reduce the noise and vibration. Moreover, the results show that the needle dwells for
at the uppermost position, and the guide performs shogging operation for
. This motion has the effect of enhancing the stability of loop formation during knitting operation by speeding up the shogging motion of the guide bar of the domestic raschel machine for industrial fabrics.

Yang, Joong-Sik ; Kim, Min ;
Textile Science and Engineering, volume 42, issue 2, 2005, Pages 71~77
For high quality cotton spun yam, the drafting conditions in the ring spinning machine have to be determined considering the cohesive force of the roving which is related to its twist factor, count and constituent fiber properties. In this study we determine the break draft efficiency by measuring the rotational speed of middle top apron and back top roller in the break draft zone of a ring spinning machine, and investigate the relationship between break draft efficiency and the quality of cotton spun yam. The results show that the break draft efficiency decreases and the count of cotton spun yam becomes coarser with increase in break draft ratio when break draft ratio is less than the optimum value. When the break draft ratio is the optimum value, the break draft efficiency reaches a minimum and the quality of cotton spun yam is improved. When the break draft ratio is larger than the optimum value, the break draft efficiency increases sharply with increase in break draft ratio due to stick-slip phenomenon, the variation of break draft efficiency becomes larger and the quailty of cotton spun yam is negatively affected. It is also shown that the higher the cohesive force of roving, the higher the break draft ratio where break draft efficiency reaches a minimum.

Textile Science and Engineering, volume 42, issue 2, 2005, Pages 78~84
laser drawing has been investigated by using a newly designed and constructed laser drawing machine, which has feed roller and take-up roller as in conventional roll drawing process. The
laser drawing of poly(ethylene terephthalate) (PET) fiber was performed with change of drawing conditions to improve mechanical properties of the PET fiber. The PET fiber were drawn continuously by
laser radiation perpendicular to the fiber axis. The physical properties of the
laser drawn PET fiber are studied by wide-angle X-ray diffraction (WAXD), birefringence, differential scanning calorimetry (DSC) and tensile testing. The improvement of mechanical properties of the PET fiber by
laser drawing is attributed to the development of more ordered crystallites and the formation of more perfect crystalline structures in the PET fiber.
Effect of Internal Structure on Deformation Behavior and Domain Mechanical Properties of 3,3'-Dimethyldiphenyl 4,4' -diisocyanate(TODI)-Based Polyurethanes

Textile Science and Engineering, volume 42, issue 2, 2005, Pages 85~92
New types of polyurethane (PU) have been synthesized using 3,3'-dimethyldiphenyl 4,4'-diisocyanate (TODI) in order to test the effect of the chemical structure of hard segment on the domain/segment deformation behavior and mechanical stability of polyurethane. The effect of hard segment (H/S) content on the domain/segment deformation behavior was measured with SAXS and FTIR-dichroism methods. For TODI-based PU of low H/S content, the long axes of individual hard domains of lamellar type were aligned along the uniaxial stretching direction. When the hard segment content increases, the hard domains form lamellar stacks and those stacks are either rotated or tilted towards the initial stretching depending on their H/S content. For polyurethanes of highest HIS content, the selective domain break-up phenomenon was found to be a major restructuring process. Segmental orientation behavior observed with FTIR-dichroism is consistent with domain deformation behavior observed with SAXS. Compared with MDI-based polyurethane, TODI-based polyurethane exhibits better mechanical stability and this is explained in terms of the good packing behavior of hard segments in the TODI-based polyurethanes.
A Study on the Weaving Techniques of Gold In-Woven Textile
Ro, Jin-Sun ;
Textile Science and Engineering, volume 42, issue 2, 2005, Pages 93~99
Gold in-woven textile is the general name for textile with metallic threads, especially the gold thread. Gold in-woven textiles were popular in the Goryeo and Choseon dynasty. This is proved by ancient literature and archaeological findings. But the technology was lost in Korea. But, now a kind of gold in-woven textile is successfully produced on a Chinese draw loom with a major pattern sheet. The following work is to weave a gold in-woven textile; pattern analysis and design, material preparation, loom setting and weaving, and the last is inspection.

Textile Science and Engineering, volume 42, issue 2, 2005, Pages 100~107
We developed a fatiguing system that is capable of simulating the actual compressional fatigue of nonwovens in a daily use. The fatigue test was performed at nine different cycles. The compression properties including compression energy, compression linearity and thickness at given pressures with different compressional fatigue cycles have been evaluated with KES-FB3 after fatiguing the samples upto the given cycles. We examined the several formulas for the compression and recovery curves. We found the best equations describing the compression and recovery behaviors. Compression and recovery parameters,
, have been evaluated. The result of compression test for 3D(perpendicular laid) and 2D(spunlace) nonwovens shows different compressional behavior due to the different geometrical properties.

In this research, we have developed a fusing condition optimization process to maximize bonding strength between a fusible interlining and a fabric using Taguchi method (also called 'robust design', 'quality engineering', etc.). The four target fusing parameters including types of fusible interlining, fusing temperature, fusing pressure, and fusing time are selected to optimize the quality of fused composites. The Taguchi processes 1) calculate the SN (signal-to-noise) ratios of repeated experimental observations, 2) find the corresponding influential fusing conditions for a given fabric, 3) determine the optimum values of the fusing conditions, 4) calculate the prediction interval of maximum bonding strength of the fused composite with optimum fusing conditions, 5) certify the applying Taguchi processes, and finally, 6) compare the expected losses between before and after improving bonding strength of the fused composite. The new process has been applied to three different fabrics using the specified experimental design with an optimum orthogonal array table. Conclusively, we can easily determine the optimum fusible interlining and fusing process conditions with simple experiments.

Jung, Kyongyong ; Na, Youngjoo ;
Textile Science and Engineering, volume 42, issue 2, 2005, Pages 118~128
In order to develop fashion products of sensibility and high quality, we propose the fashion design recommendation system (FDRAS), a design expert system. We programed the co-operative filter personal techniques, using collaborative filtering to search the textile and fashion design database, and this was an effective tool providing a fashion design fitted to customer's need. A user-interface tool is developed to recommend fashion designs according to the user's need, and enhance the efficiency in user interface. We selected 41 fashion design drawings from a picture dictionary to prepare the questionnaire: 15 collar types, 8 sleeve types, 10 skirt types and 3 lengths, and 5 color tones, and performed a survey for establishing the database. 889 subjects participated in this survey. Developing this recommendation system, database of the designs and the related sensibility, and transformation algorithm was established. The visualization of the results of recommended designs to a consumer is presented in 2D and 2.5D graphics. The performance of FDRAS is tested according to three algorithms in terms of mean absolute error (MAE).

Textile Science and Engineering, volume 42, issue 2, 2005, Pages 129~135
In this work, the heavy metal ion adsorption behavior of activated carbon fibers (ACFs) containing chelating functional groups were studied. The ACFs were modified by fluorination and glycidyl methacrylate (GMA) graft polymerization in order to introduce chelating functional groups, such as iminodiacetate (IDA) groups, on the carbon surfaces. Fourier transform-infrared spectrometry (FT-IR) and X-ray photoelectron spectroscopy (XPS) were used for the analysis of surface properties of the ACFs. Specific surface area was calculated from Brunauer-Emmett-Teller (BET) equation for
adsorption at 77 K. In the result of XPS, the relative intensity of oxygen peaks increased with increasing treatment times of fluorination, indicating that surface oxidation occurred due to the increased treatment time of fluorination, in spite of decrease in specific surface area by pore blocking. However, the adsorption of the heavy metal ion significantly increased with increasing treatment time of fluorination. It was understood that the IDA groups of the fluorinated ACF surfaces were introduced by GMA graft polymerization and the IDA groups led to an increase in the adsorption of heavy metal ions.

A plasma treatment using saturated
gas was employed to improve the surface characteristics of PVA films. PVA films were treated for different treatment times, at various discharge powers and reaction pressures. The water contact angle of the
plasma-treated PVA films increased, and surfaces of different chemical composition resulted from
