With increasing global interest in environmentally friendly materials and the consequent rise in demand, there is a growing need for alternatives to synthetic fibers, which can cause skin diseases and other side effects. The fashion industry is emphasizing material sustainability owing to concerns about increasing carbon emissions. Moreover, consumers express a strong desire for ecofriendly and sustainable materials. Therefore, clothing brand companies are developing eco-friendly products to enhance their corporate image. Hemp fibers are recognized for their functionality and are utilized as crucial materials in the development of eco-friendly products by global fashion companies. In this study, we produced socks that effectively improve foot health using hemp stem bark extract fibers and demonstrated the positive efficacy of natural fibers through functional and wearability evaluations. Hemp stem bark extract fibers showed 99.9% antimicrobial effectiveness against bacteria responsible for sweat-induced bacterial proliferation and odor, when blended with lyocell fibers and woven into fabric to manufacture socks. Wearability evaluations of these terry cloth socks confirmed a reduction in foot odor and fatigue among the participants with a consumer satisfaction of 4.63/5. These findings confirm the effectiveness and positive impact of the natural antimicrobial properties of hemp fibers and terry cloth structure in improving foot health.

The hydrophobic nature of the wool surface give rise to difficult penetration of dye molecules. Among all the methods of modification, graft polymerization is an attractive method to impart a variety of functional groups to a polymer. Grafting has been made by irradiating the light on the polymer in the presence of a solvent containing monomer. The energy source commonly used are high-energy electrons, X-rays, UV and visible light. UV irradiation is a relatively low-energy radiation in comparison with others since it has the least possibility to change bulk properties. In the present paper, a photo-reactive dye was synthesized from quinizarin by the reaction with methacryloyl chloride. The synthesized dye was continuously grafted onto wool fabric at room temperature by UV irradiation. Several key parameters including UV energy, dye concentration and pH have been examined to understand their influence on the photoreactive coloration.

A mixed bi-functional reactive dye has been applied to the cotton and the cotton/hemp blend and their dyeing and fastness properties were compared. The cotton/hemp blend exhibited higher exhaustion values and better build-up property than cotton, presumably due to the lower crystallinity. Hence, the reproducibility of dyeing of hemp is expected to be excellent. Fastness properties of reactive dyes on cotton and cotton/hemp blend are found to be almost identical. The results obtained suggest that hemp in cellulosic fabric could be used as an important alternative to universal cotton in cellulose fabrics.

In order to introduce new functions onto textile fabrics, nylon and cotton were treated with green tea extracts. And then the anti-oxidant activity of fabrics treated with the extracts was evaluated by Blois method using DPPH ($\alpha$, $\alpha$-diphenyl- $\beta$-picrylhydrazyl). The anti-oxidant activity was exhibited on the textile fabrics treated as well as by the extracts itself. The cotton fabric treated with 10% o.w.f. of extract appeared to have almost 90% of anti-oxidant activity and 95% was obtained for nylon.

Power net fabric is one of the highly extensible two-way fabrics. Power net structure shows special characteristics in the wearing of final functional clothes. This research evaluated effects of treatment temperature on proportional extensibility and shrinkage ratio of spandex at a given wale length. As treatment temperature increased, extensibility increased proportionally to the standard length of the sample and the shrinkage ratio in the direction of course and wale increased. The pulling-out length increased proportionally to the standard length of the sample. However it was affected by the effect of treatment time and temperature due to the thermal properties of spandex filament yarn.

In this study, the comfort properties of cotton and Hanjee fabrics dyed with Inonotus obliquus and treated with illite were evaluated and compared. Results were as follows; 1) W/T values and WC/W values of cotton and Hanjee fabrics were decreased when they were dyed with Inonotus obliquus and treated with illite. 2) Although air permeability of cotton fabrics was higher than that of Hanjee fabrics, air permeability of cotton and Hanjee fabrics dyed with Inonotus obliquus and treated with illite was decreased. 3) Thermal conductivity of cotton and Hanjee fabrics dyed with Inonotus obliquus was increased whereas thermal retain property was decreased. 4) Water absorption of Hanjee fabrics was higher than that of cotton fabrics. Water absorption of cotton and Hanjee fabrics dyed with Inonotus obliquus and treated with illite was increased. 5) Deodorization rate of Hanjee fabrics was greater than that of cotton fabrics.

Polypropylene nonwoven fabrics were exposed to He/$O_2$ atmospheric pressure glow discharge plasma. Surface chemical analysis and contact angle measurement revealed the surface oxidation by formation of new functional groups after plasma treatment. Weight loss (%) measurement and scanning electron microscopy analysis showed a significant plasma etching effect. It was investigated in low-stress mechanical properties of the fabrics using Kawabata Evaluation System (KES-FB). The surface morphology change by plasma treatment increased surface friction due to an enhancement of fiber-to-fiber friction, resulting in change of other low-stress mechanical properties of fabric.

Optimum dyeing conditions of green tea extracts were investigated toward nylon, cotton, rayon, and tencel fabrics. Affinity of green tea extracts was exhibited much higher onto nylon fabric than the other cellulosics. As for nylon, the adsorption was increased with the increase of dyeing temperature and optimum dyeing pH was around 4~6. Buildup property of green tea extract was good showing a linear relationship between concentration of the extracts and color strength of dyed fabrics within experimental range. Color fastnesses were good to excellent in general except to light.

The antibiotic reactive dye was synthesized by coupling of reactive chromagen with diazotised silver sulfadiazine for an antibiotic property. The highly reactive MCT(monochlorotriazine) and DCT (dichlorotriazine) type functional groups which have heterocyclic ring and moderately reactive VS-type dye that has good dyeability were used for reactivity. The synthesized antibiotic reactive dye is expected to impart the antibiotic function with high durability on cotton fabric only by one-step dyeing process without further finishing treatment. The synthesis of antibiotic dye was easily proceeded thorough diazotisation of silver sulfadiazine and coupling with suitable chromogen. The dyeability of synthesized dye for cotton fabrics was excellent and the dyed fabrics showed good level of lightfastness, resistance to washing and rubbing. The antibiotic tests revealed that the dyed cotton fabrics with the synthesized dye had very good antibiotic properties.
