  • Understanding awareness and wearing behavior of functional textiles for silver generation is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, the level of awareness for both comfort-oriented and health/safetyoriented functional fabrics in high health-conscious group was much higher than that in low health-conscious group. In number of wearing times, health body and high-conscious group wear comfort-oriented fabrics more frequently, while weak body group wear health/safety-oriented fabrics more often. The health-consciousness significantly influenced the possession of active sportswear with various functions. Second, the awareness of functional fabrics in exercise activities groups was much higher than that in exercise-conscious groups. High exercise activities group know more about the wet sensation-related fabrics and clothing materials for outdoor activities. Low exercise-conscious group put on health/comfort-oriented fabrics for casuals more frequent than functional fabrics for sportswear. High exercise activities group preferred to wear sportswear suitable for outdoor activities. The aged people have a lot of health/comfort-oriented functional casual wear appropriate for indoor activities regardless of exercise-consciousness. However, the more they enjoy exercise activities the more they are interested in functional sportswear. Even though they were unconcerned with exercise, older people are interested in functional casual clothes. As a conclusion, the high interest in health and exuberant activities in silver generation arose the necessity of new multi-functional clothing products.

  • Studying awareness, importance, satisfaction, and wearing behavior of functional textiles for active silver generation related with gender and age is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, silver generation considered all the clothing comfort sensations important when wearing clothes, such as tactile sensation, clothing pressure sensation, thermal/wet sensation, and motion sensation in human physiological aspect. Also, stretchy fabrics were ranked first in awareness, the number of wearing times, and satisfaction of comfort functional fabrics. More than 30% of silver generation have fifteen items out of 36 functional clothes. Second, in analysis of awareness by gender on functional clothing products, women were more aware of health/safety-oriented fabrics than men were. Otherwise, men had more knowledge about the water-related properties of functional fabrics than women have, such as water/moisture absorptive and water-repellent/vapor permeable fabrics. While women have more indoor casual wear, men had more active sportswear. Also, women expressed a strong preference to the stretchy function of fabrics.

  • The functional non-woven fabrics have been applied in various industry fields, such as clothing, hygiene, environment, medical and so forth. The functional non-woven fabrics were manufactured by meltblown and finishing processes. These functional non-woven fabrics were based on 5wt% masterbatch using 2,000ppm nano-silver resin composite. Silver is one of the most universal antimicrobial substances. Nano-technology enables us to expand the surface area of silver particles markedly. Silver nano particles were successfully produced less than 50nm in size. The functional non-woven fabrics including nano-silver particles showed excellent antibacterial activities against Staphylococcus aureus (ATCC 6538) and Klebsieila pneumoniae (ATCC 4352). From the results, functional non-woven fabrics including silver nano particels probably will be available as a good and safe antibiotic alternative, such as mask medium filter, water purifier filter, hygiene wet tissues, marine products pad and so forth.

  • Silver ions or silver nanoparticles have multi-functional properties. The cotton fabrics for providing multi-functional properties were treated with a nanosilver powder, UV-absorbers, and dimethyloldi-hydroxyethyleneurea (DMDHEU) alone and mixed solution. The physical properties, UV protection, antibacterial, and deodorizing properties of treated cotton fabrics were evaluated. The results were as a follows. The UV protection of cotton fabrics were increased by the application of a nanosilver and Uv-absorbers mixture. The UV protection of treated fabrics were improved by nanosilver/DMDHEU/UV-absorbers mixed solution. The wrinkle recovery properties of fabrics treated with DMDHEU and nanosilver improved. The stiffness of fabrics are decreased by a nanosilver/DMDHEU/UV-absorbers mixed solution. The antibacterial properties of the fabrics treated with nanosilver/DMDHEU/UV-absorbers mixed solution is 99.99%. The functional properties of cotton fabrics are shown to be better with aanosilver/DMDHEU/UV-absorbers mixed than treated with nanosilver alone.

  • Lifestyle of Health and Sustainability (LOHAS) influences the development of hygienic and health-oriented functional textile products; consequently, there has been an increase in the prospects for environmentally friendly natural dyeing products with functional and sensitive characteristics. Therefore, the present study expresses a functional manifestation on fabrics by treatment with chitosan and tannin using natural Coptidis Rhizoma. Cotton and wool fabrics dyed with Coptidis Rhizoma after treatment with chitosan and tannin. Consequently, the antibiosis of fabric dyed with Coptidis Rhizoma was excellent with 99.9% bacterial reduction for Staphylococcus aureus and Klebsiella pneumoniae in both fabrics. The deodorization rate was more than 90.0% in both fabrics after 120 minutes. The UV-A protection rate was 88.2% and the UV-B protection rate was 87.7% for cotton. The UV-A protection rate was 88.2% and the UV-B protection rate was 84.3% for wool fabric. Therefore, both of the dyed fabrics showed excellent UV protection by treatment with only chitosan and tannin, without mordants. Therefore, chitosan and tannin treatments were able to manifest functionalities in the fabrics dyed with Coptidis Rhizoma.

  • The polyester fabrics were treated with the chitosan with various solubility in optimized treatment condition. The treatment method was discussed to be a high functional finishing for the polyester fabric to obtain the high moisture absorption and anti-microorganism property by evaluating the effect of the chitosan purification method on the yield and anti-microorganism property of the chitosan. On the other hand, soluble polyurethane was added to the chitosan treatment solution and/or plasma pretreatment was done. The addition of soluble polyurethane give a high add-on ratio as well as a linen like effect of treated polyester fabric. The results were as follows: 1. In the treatment of polyester fabric by the chitosan solution, a soluble PU resin and low temperature plasma treatment were done to obtain high binding force between the fabrics and the chitosan. The add-on rate and the moisture absorption ratio of the fabrics treated with the chitosan-PU after treated with the plasma slightly increased more than those of the fabrics treated with the chitosan only. 2. Anti-static property of the fabrics treated with the chitosan decreased rapidly with increasing of the chitosan concentration. The washing fastness of the fabrics treated with the chitosan-PU after treated with the plasma was better than those of the fabrics treated with chitosan only. The wrinkle resistance of the treated fabrics decreased constantly with the concentration of the chitosan. The bending rigidity of the treated fabrics increased greatly. On the treatment of polyester fabric under optimum condition, the microorganism reduction rate kept above 90% after 10times launderings. 3. As the polyester fabrics which has flat yam was used as a weft yams were treated with the chitosan-PU as give a functional finishing effects such as durability, moisture absorption, anti-static and anti- microorganism property. Treated polyester fabric showed a good functional finishing effect and a linen like property.

  • The natural dyeing of hanji cotton fabrics with guava leaf extract was investigated. The temperature and time of dyeing were $40^{\circ}C$ and $90^{\circ}C$ for eighty minutes, respectively. In addition, the dyebath has been set at pH 5. Sn pre-mordanted fabrics showed the highest K/S value. Regardless of dyeing temperature, K/S values were high when Al, Cu, Fe-mordanted fabrics were dyed in post-mordanting and Sn-mordanted fabrics in pre-mordanting. The dyeing equilibrium was shown at the fourth time of repeated dyeing. In the processing of hanji cotton fabrics, K/S value was high when hanji cotton fabric was treated with soybean milk at $90^{\circ}C$. Similar K/S value of dyeing was shown when fabrics were processed with chitosan, regardless of dyeing temperature. High K/S value of dyeing was seen when fabrics processed with gallnut tannin at 40. Fabrics dyed with acidic water extract showed yellowish color. Fabrics dyed with alkaline water extract showed reddish color, and fabrics dyed with ethanol extract showed greenish yellow color. In case of Sn-mordanted fabrics, the washing fastness level was between 3 to 4, and other dyed fabrics showed low fastness. The dry cleaning fastness also showed very excellent result with level 4-5. The rubbing fastness of the fabrics was better in dry rubbing than in wet rubbing. For the light fastness, all dyed fabrics showed low fastness. For antibacterial activity, the dyed fabrics with guava leaf extract showed 99.9% of high antibacterial activity. Hanji cotton fabric maintained certain deodorization in the state of raw fabric. All dyed fabrics showed higher UV protection rate than control fabric.
