The influence of the 'well-being' trend on the every day life of our society can be found by recent books, articles, and magazines. The purpose of this study is to analyze the well-being trend and its effect on the current knitwear fashion. The results of this study can be summarized as follows; (1) The 'well-being' trend is very different from the past life style and it will be a preceding life style in 21st century. (2) The preference for organic food and the promotion of 'colorful menu' came from the 'well-being' trend. And, the yoga, zen, meditation, aroma-therapy, spa, and massage are also under the influence of 'well-being' trend. (3) The Neo-Hippie look and Neo-Vintage look are connected with the 'well-being' trend. (4) The influences of 'well-being' trend on the current knitwear fashion are shown in the hand knitting (bulky knit & crochet), twin sets including cardigans, hand crafted details, natural colors, and natural materials.

In this study, the mechanical properties related to the fabric appearance of well being functional bamboo knitted fabric before and after loess dyeing were evaluated. The mechanical properties of fabrics were measured by KES-F system, that is, shape retention, draping, wrinkle recovery, compression property, and surface properties, and total hand value of three types of knitted fabric, 100% bamboo, 100% cotton, and bamboo / cotton blend (60 / 40) were evaluated before and after loess dyeing. As a result, it was found that appearance density, shape retention, and drape coefficient of cotton knitted fabric were greater than those of bamboo knitted fabric. After loess dyeing, shape retention and drape coefficient, wrinkle recovery of bamboo knitted fabric improved and WC/C and MMD/SMD decreased. According to THV, the hand of bamboo/cotton blend knit is the best among three samples by compensation the weak properties of the two fiber. Therefore, loess dyeing seemed to be a good method for improving shape retention and hand value of 100% bamboo and bamboo blended fabric.

In the manufacturing of large scale composite structures, the cost-effective processing and the enhancement of structural performance are critical. One of the most effective ways for this purpose is to use stitched multiaxial warp knitted (MWK) perform in the resin transfer molding process. This study reports the effect of stitching on the mechanical properties of MWK composites, and the feasibility processing of the thick U-beam structure utilizing the stitched preforms. Permeability of the preform, viscosity and cure property of the epoxy resin have been measured. The results of resin flow analysis has been used in determining the gate/vent locations of the RTM mold. Cross-sectional observation of the channel beam prototype demonstrated that the resin impregnation was almost complete, except for some surrounding area of stitched yarns.

In recent years, compression molding of long fiber-reinforced thermoplastics has been increased in commercial aspects. In the process of compression molding of composites, the flow analysis must be developed in order to accurately predict the finished part properties as a function of the molding process parameters. In this model FRTP is assumed to be nonisothermal fluid, which has different viscosities in extensional and in shear. For verification of the model, the formation of a knit line in the L-shaped parts is compared with that of experiments results. In this paper we will discuss the effects of extensional & shear viscosity ratio and slip parameter $\alpha$ on the other modle fill-ing parameters.

The purpose of this study was to investigate the effect of demographics and general buying characteristics of knitwear consumers on their buying decision-making process. In this study, a self-administered questionnaire was distributed to young career women and female undergraduate students. of 580 questionnaires, 496 were used in the following analysis. The data was analyzed with SPSS package. T-test, one-way ANOVA and x² analysis were used to investigate the impact of characteristics of the consumers on their demographics. The high school graduate-career women group, relative to other groups, showed significant differences in practical aspects in buying knitwear. Second, the knitwear buying places of consumers were significantly different depending on the demographics and general buying characteristics of knitwear. The higher annual knitwear buying expenses and the lower knitwear buying frequency, the more a consumer shopped in department stores. Third, the knitwear satisfaction level of consumers was significantly different depending on their demographics and general buying characteristics of knitwear. career women relative to female undergraduate students showed significant differences in satisfaction with design, quality and yarns.

Graphite oxide (GO) was produced using the modified Hummer's method. Poly(p-phenylene sulfide) (PPS)/reduced graphite oxide (RGO) composites were prepared by in situ polymerization method. The electrical conductivity of the PPS/RGO composites was no more than 82 S/m. It was found that as GO content increased in the PPS/RGO composites, the crystallization temperature and electrical conductivity of the composites increased and the percolation threshold value was at 5-8 wt% of GO content.

The purpose of the study was to investigate the changes of drapability and mechanical properties with folded yarn conditions. The samples were knitted 100% cotton yarn with hand-knitting machine. Mechanical properties were measured by Instron and Kawabata tester. Drapability was measured by Drapemeter. The differences in each sample were observed in the experimental results. This study showed that folded conditions were important conditions for fabric handle and properties.

Stress analysis was conducted with finite element method to study the stress distributions in both single-pin and multi-pin loaded composite laminates. The various parameters involved in the design of the joint method were considered. The stress distributions in the vicinity of the holes were predicted considering the effects of various parameters such as the lay-ups, number of pins, number of rows, row spacing, and hole patterns. The results show that the performance of joint is greatly affected by these parameters.

To study numerically the mechanical behaviors of advanced composite materials considering the microscopic phenomena as well as the macroscopic properties and behaviors, a multi-scale modeling and analysis by the mathematical homogenization method with the help of the finite element method(FEM) are reviewed. The hierarchical modeling strategy and the formulation are briefly described first to give some idea of the multi-scale framework. The latter half of this article focuses on the verification of the multi-scale analysis by the homogenization method in its applications to real advanced materials. The first example is the verification of the predicted macroscopic(homogenized) properties based on the microstructure of porous ceramics. In spite of the complexity of the random microstructure, the error between the predicted and the measured values was only 1%. Next, two applications to the process simulation of fiber reinforced polymer matrix composites are presented. The permeability characteristics are evaluated for sheared weave fabrics for resin transfer molding(RTM) simulation, and the thermoforming of FRTP sheet is analyzed considering the large deformation of the knit structure during the deep-draw forming was verified by comparison with the experimental results.

The fragrant fabrics are prepared by the attaching microcapsules using acrylic binder. To improve the handle of fragrant fabrics, pretreatment by softener is suggested. The durability of fragrant fabrics and the change of their handle are investigated. It is carried out One-way ANOVA and Duncan test to determine bending properties, shear properties, surface properties of untreated, SO-MC and BI-MC by Kawabata system. BI-MC shows significant differences in B and 2HB. SO-MC shows significant differences in G and 2HG. It turned out the pretreatment by softener mitigated the effect of binder and makes fabrics softer than untreated fabrics.
