Recently, with an increase of interest in hygiene of textile products, research related to finishing technology to impart various functionalities, such as antibacterial and deodorizing properties, has also required. Therefore, in this study, the improvement of comfort was examined by analyzing the change of moisture characteristics and antibacterial and deodorizing properties of underwear fabric by chitosan microcapsule(CH-M) finishing. The results revealed that moisture absorption time of the fabric shortened, diffusion rate increased, while absorption rate slightly increased because of microcapsule finishing. In addition, the one-way transfer capacity of the microcapsule finished fabric was 17.69, which improved moisture transfer to one side, while OMMC showed the values of 0.32 and 0.37 for untreated and finished fabrics, respectively, which slightly increased after finishing. In the case of untreated fabric, antibacterial activity was 89.0% against Staphylococcus aureus and 70.3% against Klebsiella pneumoniae; however, both strains showed 99.9% antibacterial activity by CH-M finishing. An excellent bacterial reduction rate was also observed. In the case of the CH-M finished fabric, there was a deodorization effect exceeding 99% up to 120 minutes, and it showed an excellent deodorization effect of more than 99% even after 10 repeated washings.

In this study, for natural leather use, the phytoncide oil of antibacterial materials was encapsulated in several micro-diameter shell which slowly releases from the leather treated with antibacterial microcapsules. The microcapsule was synthesized by in-situ polymerization of urea and formaldehyde. The effects of surfactants on the average particle size and distributions, morphologies and antibiosis were investigated to design microcapsule.

The various size and morphology microcapsules were prepared to produce smell sweet by heating condensation reaction of melamine and formaldehyde using 5-types of surfactants such as the laurylbenzenesulfonic acid sodium salt (SDS), polyvinylpyrrolidon (PVP), polyvinyl alcohol (PVA), Span-80 and 2-acrylamido-2-methyl-1-1 propanesulfonic acid (AMP). As result it was found that the size and morphology of microcapsule is intimately associated with a kind of surfactants. In order to prepare microcapsule with antibacterial, the silver nanoparticle was prepared by gamma-irradiation. microcapsule with silver nanoparticle was prepared.

Microcapsules containing 2, 4, 4'-trichloro-2-hydroxydiphenyl ether and perfumes were prepared by the coacervation using poly (vinyl alcohol) and crosslinking agents. Effects of dispersing agents, core materials, agitating speed and crosslinking agents on microcapsule size were investigated. The mean and deviation of microcapsule diameters decreased with increasing agitation speed. The diameters of m;crocapsules decreased with increasing dispering agent concentration at 6, 000 rpm of agitation speed, but it was not changed at 10, 000 rpm. The dispering effect of PVA is better than that of gum arabic. The slight increase in the diameter of microcapsule was observed when the amount of core material was increased. As the amount of crosslinking agent was increased, the diameter of microcapsule was decreased.

Microcapsules containing 2,4,4'-trichloro-2-hydroxydiphenyl ether (DP) and perfumes were prepared by the coacervation using poly (vinyl alcohol) and crosslinking agents. Internal phase content, percent releasing of core materials, antimicrobial activities of microcapsules and fabrics treated with them were investigated. The internal content of microcapsules containing perfumes and DP are increased with increasing perfumes. The internal content of cacharia in the microcapsue was higher than that of lemon and its maimum value was 93%. The microcapsules containing perfumes and DP did not release cacharia and lemon at roonl temperature. But the amount of perfumes released from microcapsules were increased with temperature and time of microcapsules containing DP and perfumes showed 100% reduction percentage of bacteria. The size of obstruction of fabrics treated with microcapsule containing DP and perfumes were increased with DP content in microcapsules.
