This paper studied the ban on 'Po[포]', including hemp and ramie, on the basis of Joseon Wangcho Silok (the True Record of Joseon Dynasty). Po is the important point which can help to understand the people's life related with clothing. This paper showed that in the early years of the Joseon Dynasty, the state had forced kinds of bans on some fabrics many times. Among the bans of the fabrics-making the main part was the bans on Po, along with rice, used as money in those days. The state had on Po enacted on the policy to intend to promote paper money circulation more widely. However, people didn't want to use paper money. The reason why cloth could be practical and functional as a kind of currency was that people could make clothes with it at any time while they used it as money. People avoided using paper money that could not be used in that way, and so did public officials. At that time, Po that was generally used as money was the hemp of five warp threads. The measurement of the hemp in 7chi[촌; a Korean inch] by 35chok[척] and 32cm by 16m by modern metric. It also showed that it has been thought that the blended fabrics are the fabrics that were made of raw silk-threads and cotton threads as warp and weft respectively. However, the fact that there is a record of 'Jeo Ma Gyo Jik Po[저마교직포의]'(blended fabrics and clothes made of ramie and hemp) and there appear the new proofs of the fieldwork investigation shows that the concept of blended fabrics might be various or changeable as time passed.

Durable softening water repellents such as PODCWs were prepared by blending cationized compound of poly(octadecyl methacrylate-co-2-diethylaminoethyl methacrylate), of which synthetic methods were reported in the previous paper, activated polythylene, waxes, and emulsifiers. Water repellency of prepared PODCWs was measured by performing water repellent finish to various fabrics, PODCWs showed a good water repellency for P/C blended fabrics and their repelling tendency was in the order of P/C blended fabrics>cotton fabrics>nylon taffeta. The initial water repellencies of PODCW-1 and PODCW-2 were 100 and $100^{-}$ points, respectively, for P/C blended fabrics. And also, PODCW-1 and PODCW-2 were confirmed as durable water repellents with the results of making little difference of water repellency as ${\pm}5$ point after and before washing.

In the preparation of acrylic water repellent(EDLWC). quaternized 2-diethylarrunoethylmethacrylate-stearylmethacrylate copolymer (DSACC) and quaternized 1-Iaurovlbis(aminoethyl)-2-dodecylimidazoline(LDDIC) were selected as a basic resin and the improving agent such as softening effect and hydrostatic pressure of the water repellent. EDLWC was prepared by blending waxes and emulsifier for waxes with various ratio to DSACC and LDDIC. As the results of the measurement of water repellency, washable, tear strength and crease recovery to polyester-cotton(P/C) blended fabrics treated with EDLWC only or addition of textile finishing resin, the physical properties were increased. Sodium acetate was the most effective catalyst in the water repellency among the various kinds of catalyst. and the reasonable concentration of the catalyst was 1. 4 wt%. EDLWC was confirmed as durable water repellent with the results of making little difference of water repellency as ${\pm}5$ point after and before washing. The reaction mechanism between P/C blended fabrics and EDLWC in the presence of catalyst was proposed. And also, the longitudinal view of the P/C blended fabrics treated with water repellent was observed with scanning electron microscope.

To prepare a durable softening water repellent, quaternized octadecyl methacrylate-2-diethyl-aminoethyl methacrylate as a mother resin and quaternized 1, 3-dioctadecyl-2, 7-dioxy-6, 8-di(2-hydroxyethyl)-1, 3, 6, 8-tetraazacyclodecane which increase the softening effect and the hydrostatic pressure blended with waxes and their emulsifier in various proportions to give water repellent PADWC. As the results of the measurement of water repellency, washable, tear strength and crease recovery to polyestercotton(P/C) blended fabrics treated with PADWC only or addition of textile finishing resin, the physical properties were increased. There was no significant lowering effect in water repellency when PADWC was treated the antistatic agent by the one-bath method, and the effect of water repellency by the adding the catalyst was studied. PADWC was confirmed as durable water repellent with the results of making little difference of water repellency as ${\pm}5$ point after and before washing.

This study was performed to find ways to improve the wearing comfort of high school boys' summer uniforms. The subjects were 640 boy students of high schools in Cheongju and Ansung city. The data was collected self-administered questionnaires to measure the actual wearing condition and the wearing satisfaction. Factor analysis, t-test, and F-test were used for data analysis. The results were as fellows: 1) Most students were wearing shirts made of polyester/rayon blended fabrics and pants made of wool/polyester blended fabrics. 2) Most students were wearing round neckline T-shirts or running shirts as underwears of the shirts, and trunks as pants. 3) About a half of respondents had altered their summer uniforms, and main alteration of their uniforms was focused on making their pants narrow. 4) The wearing satisfaction of uniforms were classifies into three factors: aesthetic, moving function, thermal comfort wearing sensation. 5) They evaluated the wearing sensation of school uniforms of shirts and pants with low satisfaction. 6) There were partially significant differences in three factors of the wearing satisfaction according to the uniform's fabrics, the wearing of underwear and the alteration of uniform.

In the wool textile industry, the necessity for technology development has been steadily raised to create improved fineness and yarn count of existing wool yarns with thick fineness for ensuring higher quality grades of wool yarn. Recently, through controlling fineness of wool yarn for making finer wool in relation with environmentally-friendly and high-sensitivity trend, a differentiated continuous drawing process where the quality of wool can be artificially manipulated has been suggested in the latest textile industry. This study investigated the basic conditions during the continuous drawing process which enable to manufacture wool yarn with fine count by controlling reducing agent treatment, physical drawing and drying after reducing agent treatment, and oxidizing agent post-treatment conditions. Furthermore, this study reviewed the drawing effects by applying the basic conditions for reduction and oxidation reaction in the drawing processes of wool/cashmere, wool/silk, wool/polyester blended yarns as well as such wool yarns. Also, in order to review the practicability, this study examined the physical properties and dyeability of drawn wool yarn applied textile materials in comparison with normal wool yarn applied textile materials.
