The wearing comfort of garment is governed by two kinds of characteristics such as moisture and thermal transport properties and mechanical properties of fabrics. The porosity influenced by yarn and fabric structural parameters is known as main factor for wearing comfort of garment related to the moisture and thermal transport properties. This study investigated effect of porosity of composite yarns to the moisture and thermal comfort properties of composite fabrics made of hollow composite DTY and ATY yarns. The theoretical porosity and pore size were inversely proportional to cover factor of fabric, but cover factor was not correlated with experimental pore size. The wicking property of hydrophobic PET filament fabric showed inferior result irrespective of porosity, pore size and cover factor. The drying rate was superior at composite fabrics with high pore size and low cover factor, and pore size was dominant factor for drying property. On the other hand, thermal conductivity of composite fabric was mainly influenced by cover factor and not influenced by porosity. Air permeability was influenced by both porosity and cover factor and was highly increased with increasing porosity and decreasing fabric cover factor.

Recently, smart wearable products, including electromyography (EMG) measurement devices and clothing, have been developed to monitor users' exercise levels, muscle activation, and muscle balance more effectively during fitness activities. However, technical and socioeconomic barriers, such as flexibility and durability, still pose challenges in terms of comfort, ease of wear, and wearability of smart clothing, which includes devices and circuits. To address these issues, this study developed a wearable EMG device integrated with clothing to collect valid EMG signals from desired muscles while maintaining comfort, functionality, and ease of wear. After deriving a combined structure that could stably position the wearable device within the clothing, a prototype was manufactured and evaluated for fit, compression, comfort, and exercise comfort test by ten participants (height = 176.2 cm, weight = 76.4 kg, chest circumference = 101.2 cm). The study found that the prototype had smaller circumferences around the chest, waist, and abdomen compared to commercial products, resulting in lower ratings for wearing comfort and ease of wear. However, the prototype received high ratings for fitting, pressure, and the exercise comfort test. Valid signals were obtained when the EMG device was combined to the prototype for the rectus femoris muscle, indicating stable positioning of the device during exercise.

To improve the deep coloring effect of PET fabrics, the alkali treated and black dyed PET fabrics were treated with 2 kinds of low refractive compounds such as acrylic resin and silicone resin. The color depth effect of treated PET fabrics was evaluated as lightness(L) change by UV-visible spectrophotometer. As the weight loss of PET fiber treated with alkali increased, the color depth of PET fabrics increased. Lightness(L) of PET fabrics treated with deep coloring agent was lower than that of untreated PET fabrics. The optimum concentration of treated PET with deep coloring agent was 4% o.w.s. The deep coloring effect of PET fabrics treated with silicone resin was higher than one treated with acrylic resin. PET fabrics treated with silicone resin only might be more appropriate process than PET fabrics treated with acrylic and silicone resin for giving deep coloring effect for polyester fabrics.

Generation MZ, a generic term for millennials and members of Generation Z, is an innovation-leading consumer group in the current market. This study aimed to examine the impact of the ethical consumption tendencies of millennials and Generation Z on the purchase intention of social enterprise fashion products. Data were collected from Generation MZ (15-40 years old) by quota sampling based on the demographic variables of gender, age, and region, respectively. Eight hundred responses were analyzed by descriptive statistics, factor analysis, t-test, and regressions using SPSS software. Three value factors (egoistic, altruistic, and biospheric) and three ethical consumption tendency factors (resource saving tendency, eco-friendly tendency, and consciousness of corporate responsibility) were determined by factor analyses. The results confirmed that women, who showed a higher ethical consumption tendency in all three factors, were more altruistic and biospheric than men. Furthermore, women portrayed a more favorable attitude and purchase intention towards fashion products of social enterprises. The results demonstrated that members of Generation Z were more altruistic and biospheric than millennials. Additionally, the attitude, purchase intention, and willingness to pay premium prices were higher in Generation Z members. It was confirmed that higher biospheric values correlated with greater values for the three ethical consumption tendency factors. The altruistic value affected both the resource saving tendency and eco-friendly trend, while the egoistic value had an effect on the resource saving tendency. Both attitude and purchase intention were positively influenced by all three of the ethical consumption tendency factors, and affected the willingness to pay premium prices. This was subsequently influenced by the resource saving tendency and consciousness of corporate responsibility. The results of this study contribute to understanding Generation MZ as a consumer group, and the establishment of marketing strategies for fashion companies.

The purpose of this study was to compare the similarity between actual and virtual pants using a virtual 3D CLO program. A subject corresponding to the average size of a women in her twenties was selected and an avatar with the same specifications was produced. Silhouettes of the pants were classified into trousers, slacks, and wide pants and images of actual and virtual pants were evaluated from the front, side, and back. The results were as follows: Overall, the resemblance of the trousers was evaluated higher than that of other pants. The average similarity of trousers was 4.20 at the front, 3.98 at the side, and 4.17 at the back, which was much like the actual clothing. In contrast, that of the slacks was 3.62, 3.73, and 3.79 and of the wide pants was 3.81, 3.53, and 3.97. The similarity between the actual and virtual clothing was relatively well reproduced when the shape of the pants was like the silhouette of the human body. However, if the pants were tight or loose, virtual fits failed to display the wrinkles caused by the tightness or the excessive slack. The virtual fit showed fewer wrinkles and did not depict the location and the shape of hemlines as accurately as the actual fit, although virtual fits adequately displayed the baseline and dart on the pants.

In order to improve the problems with obese women's ready-to-wear by age range, this study surveyed the actual clothing purchase and wearing of women in their 20s and 30s with normal and obese body types, and compared and analyzed their satisfaction with ready-to-wear by age and body type. First, for normal body types, both women in their 20s and 30s use department stores the most. Meanwhile, obese women in their 20s make most of their purchases at internet shopping malls, while those in their 30s mostly go to department stores. For criteria for purchasing clothing, normal women both in their 20s and 30s value design most whereas, obese women put size and fit before design regardless of their age. Normal women in their 20s and 30s both were most unsatisfied with standardized design because they could not find designs they wanted. Obese women in their 20s and 30s also showed disapproval of unvaried sizes, indicating a distinct difference in body types and age. As well, the study found that both normal and obese women wear casual style the most, followed by semi-formal style. Also, regarding the images they were seeking when wearing clothing, the normal women wanted to look fashionable, while obese women wanted to look slim, regardless of age. Both body-type groups generally like preferred semi loose-fits the most, followed by tight-fit. They however, dislike relaxed loose-fitting.

It has recently become difficult for college students majoring in cosmetology to gain employment after graduation. Under this circumstance, this study attempted to investigate students' academic achievements and employment preparation behavior based on their demographic characteristics. To accomplish this, a questionnaire survey was conducted involving 234 college men and women in Gwangju and Jeollanam-do from April 12 to 30, 2022. Out of an initial 260 questionnaires distributed, 250 were collected. Of these, 234 copies, excluding 16 poorly answered ones, were used for final analysis. The collected data were analyzed using frequency analysis, exploratory factor analysis, Cronbach's alpha, a t-test, and an F-test, employing SPSS 21.0, which revealed the following: First, concerning academic achievements based on demographic characteristics, a statistically significant difference was found in "motives to select the cosmetology department," "most important aspects for career decision," and "academic major-related license." Second, concerning employment preparation behavior, a statistically significant difference was observed in "academic year," "motives to select the cosmetology department," and "academic major-related license." The above findings confirmed a statistically significant difference in academic achievements and employment preparation behavior, ensuring a better understanding of academic achievements and employment preparation behavior. It is anticipated that those majoring in cosmetology would be more active in job preparation and ultimately obtain the profession they desire with a positive and healthy mindset.
