This study was aimed at investigating the satisfaction in relation to clothing design and size-fit for nurse uniform in Korea. The subjects were 986 female nurses working in 12 hospitals selected by convenience sampling. The data were collected by questionnaires. Using SPSS package, frequency, percentage, t-test, ANOVA and SNK test were conducted. The results were divided into 2 categories as fellows; 1) Results of the satisfaction with the size-fit and size system of the nurse uniforms : Nurses satisfied at the individual size-fit system than ready-made size system. There was a considerable difference of the satisfaction with the size-fit depending on age and clinical career. And more than half of nurses were needed the concrete and precise size system. 2) Results of the actual design condition and clothing satisfaction : Nurses wore two-piece pants suits more than classical designed one-piece style. The princess-line, convertible collar and yoke design were preferred for nurse uniform with the high satisfaction. 41.6 percent of respondents used the cap obligatory and the white color and a patterned textile were generally used. The used fabrics were only polyester and cotton/polyester mixed spinning.

Wool fabrics were dyed with the aqueous solution of C. I. Red Acid 114 mixed with methanol dissolving three kinds of barely water soluble ketones, acetophenone, 2-pentanone, and 3-pentanone. The steric hinderance and the orientation of the bigger hydrophobic part of the solvated dye molecules to the fiber slowed down the dying rate, however, loosening the wool molecule, say a little swelling, disaggeregating the dye molecules, and attaining the higher dye concentration on the fiber surface by the added solvents increased the amount of dye on the fabric. The higher concentration or/and the higher dyeing temperature helped loosen fiber molecules and made it easier for the solvated dye molecules to penetrate into the inside of the fiber. Acetophenone, the most influential solvent used, showed that the ability to loosen fiber molecules was the most important of all the three positive solvent actions mentioned above. The considered mechanism provided before reflected the fact that the dye uptake on the fabric dyed with the solvents included, except for 0.034M and 0.051M of acetophenone, was even lower than that without any solvents at $50^\circ{C}$, but all the solvents added to the dye bath increased the dye uptake on the fiber at $70^\circ{C}$.

In this study, the efficacy of water lily(Nymphaea tetragona) leaves as a new natural dye resource was investigated. For this purpose, the colorants from water lily leaves were extracted in methanol, evaporated, and powdered. Dyeing onto cotton fiber was carried out to study the effects of dyeing conditions, mordant type and mordanting method on dye uptake, color change, and colorfastness. FTIR analysis supported that hydrolyzable tannins and chrolophyll were contained in the extracted colorants. The colorants showed good affinity to cotton fiber showing Y Munsell color. Pre-mordanting method gave better results in terms of dye uptake than post-mordanting method. By mordanting, dyed fabrics exhibited various colors such as green, khaki, brownish yellow, dark brown, dark gray and so on. Colorfastness to washing and rubbing was relatively good showing 4-5 rating. The light fastness was improved 1-2 rating by Fe mordanting. The dyed cotton fabric showed antimicrobial activity.

Cotton fiber, NaOH-mercerized cotton fiber, cotton fabric, and NaOH-mercerized cotton fabric have been treated by liquid ammonia at -33.4$^{\circ}C$. The fine structures, bending properties, tensile strengthes, shrinkages for laundering, and wrinkle recoveries were studied. The treatment of cottons with liquid ammonia brought about the transition of crystal lattice ; transforming cellulose I crystal of original cotton to cellulose I and III crystal, and cellulose II crystal of mercerized cotton to cellulose II and III crystals. The degree of crystallinities were decreased in the order of liquid ammonia>NaOH/liquid ammonia>NaOH-treated cotton. However moisture regain and water absorbency for liquid ammonia-treated cotton were lower than that of NaOH-treated cotton because of a difference in swelling actions of the agents. It seems caused by intermicrofibrillar pores produced in swelling processes. The bending rigidity and bending hysteresis were decreased remarkly by liquid ammonia treatment. Therefore softness and dimensional stability were improved. The liquid amminia and NaOH/liquid ammonia-treated cottons moreover show excellent properties in tensile strength, anti-shrinkage for laundering, and wrinkle recovery.

To study the printing behaviors of Polyester and cotton(P/C) fabrics printed with disperse and reactive dyes, the effects of alkalis on the fixation of reactive dyes and the alkali-stability of disperse dyes in various methods of fixation were examined. The anthraquinone disperse dyes which have diamino derivatives as substituents without hydroxy group, such as C.I. Disperse Violet 1(D.V.1), C.I. Disperse Violet 28(D.V.28) and C.I.Disperse Blue 60(D.B.60) showed good results of fixation without regard to the concentration of NaHCO$_3$. In case of high temperature steaming(HTS) and unsaturated steaming(US)/HTS, D.V. 1 was alkali-stable and effective for P/C printing. A good result was obtained with D.V.1 and C.I.Reactive Orange 13(R.O.13) paste of 4% $K_{2}CO_{3}$. It was found that the unfixed D.V.28 bearing chloro group can hinder the fixation of monochlorotriaxinyl reactive dyes, and D.B.60 made little stain on 100% cotton. In thermosol(Tm), the dye uptake of D.V.1 was not decreased so much, but those of D.V.28 and D.B.60 were greatly decreased.

The purification, dissolution and powdering of stained waste silk obtained from weaving and dyeing process were studied for the surface modification of textile fabric and plastic materials. The whiteness of stained waste silk could be improved through degumming and bleaching with sodium hydrosulfite. The water-soluble fibroin solution can be obtained by dissoving the degummed waste silk in a boiling solution of 50% calcium chloride for 60 minutes. The salts and heavy metals contained in fibroin solution were removed by electric dialysis, wool fiber filtration and gel filtration chromatography. The fibroin powder was prepared by using a fine grinder after the alkali treatment for weakening the silk fiber. The fine fibroin powder of particle size around 30 ㎛ was obtained with a ultra fine-mill, while it was finer below 10 ㎛ with a ball-mill. The dissolved or powdered silk was applied to the surface of fabric with addition of the binder (a urethane resin). The moisture content of polyester and nylon fabrics treated with the silk solution was improved due to hygroscopic property of silk. The fine fibroin powder mixed with the binder ws coated on the surface of synthetic film by use of the air pressed sprayer. It was revealed that the hygroscopicity as well as the softness of fibroin powder coated film was much improved. Therefore, it is thought that the fine silk fibroin powder is applicable as an coating agent for the surface modification of plastic and synthetic leather.

This Paper is intended to analyze color preferences for apparel, and color preferences according to personality types. The subjects are one hundred twenty five female university students majoring in clothing, textile & design. Color stimulus are divided according to season, value and chroma, and personality types are classified into four : introverted, achieving, age-gressive and conservative. Duncan test, factor analysis and descriptive statistics have been applied to data processing. The findings are as follows. In terms of hue preferences, winter colors are most preferred and autumn colors follow. In re-gard to value preferences, low value colors have been found to be preferred and in respect to chroma preferences, low chroma colors have been found to be preferred. Seasonal colors, value and chroma show significant differences at the level of P<.001. In terms of color preferences for apparel fabrics according to personality types, winter colors are most preferred regardless of person-ality types, and autum colors follow. The introverted and the conservative dislike summer colors least and the achieving and the aggress-ive, spring colors. In respect to value preferences, low value colors are preferred irrespective of personality types. The introverted and the achieving dislike high value colors least and the aggressive and the conservative, mid value colors. With regard to chroma preferences, all person-ality types have been found to prefer low chroma colors. They dislike mid chroma color, and high chroma colors are least preferred.
