The purpose of this study is to research fabrics, colors, and arrangement of color in Jogak-bo which were developed during the late Chosun dynasty. It is expected that from the analysis of the number, distribution and arrangement of colors of Jogak-bo in the late Chosun we can suggest various color arrangements thoset can be applied to modern fashion are summarized as follows. First, as for the number of colors of Jogak-bo according to material, silk fabrics Jogak-bo used a variety of colors whereas hemp fabrics Jogak-bo mostly used one color showing contrast between silk fabrics Jogak-bo and hemp fabrics ones. Second, as for the distribution of colors of silk Jogak-bo and hemp fabrics ones, warm colors were used most frequently. On the other hand, fewer achromatic colors were used to silk fabrics Jogak-bo, and they were more applied to hemp fabrics Jogak-bo. As for the use of cold colors, fewer cold colors were applied to hemp fabrics Jogak-bo compared to silk fabrics Jogak-bo. Third, as for the arrangement of colors, various colors were used in silk fabrics Jogak-bo, but a single color or not more than 1 color was applied to hemp fabrics Jogak-bo. It well demonstrates brilliance and glamour of silk Jogak-bo and stability and unity of hemp fabrics Jogak-bo. As for the arrangement of colors of Jogak-bo, most of Jogak-bo showed contrasting colors and shades, and similar colors and shades were hardly found in silk fabrics Jogak-bo whereas they were frequently found in hemp fabrics Jogak-bo.

The purpose of this study was to help the consumer about the care of nonwoven fabrics by investigation of the properties such as launderability. shrinkage, color fastness and strenth. Materials used were two types, soft and stiff, of commercial nonwoven fabrics. Deter-gents used were neutral detergents, synthetic detergents and dry cleaning solutions(perch-toro-ethylene) The results of this study were summerized as follows; 1. Laundering of nonwoven fabrics in low temperature is more ideal as morphological changes by laundering in high temperature were more prominent than that in low temperature. 2. Ironing of nonwoven fabrics wants more attention on environmental temperature as the rate of shrinkage in high temperature was higher than that in low temperature. Neutral detergents are more desirable as the rate of shrinkage of nonwoven fabrics by laundering with synthetic detergents was more prominent than that with neutral deter-gents. The rate of shringkage of nonwoven fabrics was not affected by dry cleanining. 3. Special care is wanted in order to prevent color transfer from non woven fabrics to polyester or wool during dry cleaning or laundering as the color fastness test show that color changes of nonwoven fabrics were not affected, but that color stain was increased on polyester or wool. 4. The strength was affected by composition of fibers and types of nonwoven fabrics, soft or stiff.

3-(Hydroxyphenyl phosphinyl) propanoic acid (HPPA) has been one of the most commonly used durable flame retardant agents for polyethylene terephthalate (PET) for many years. We intended to explore the application of HPPA to cellulose fabrics as formaldehyde-free phosphorus based flame retardants (FRs) through green chemistry process. The flame retardancy of the flame-retardant treated cellulose fabrics were characterized by using inductively coupled plasma spectroscopy (ICP) and limiting oxygen index (LOI). Structural changes of the treated cellulose fabrics were carried out by thermogravimetric analysis (TGA) and Fourier transform infrared (FT-IR) spectroscopy. To enhance the flame retardancy of HPPA treated cellulose fibers, glycerol polyglycidyl ether (GPE), a crosslinking agent was employed. Both HPPA and GPE treated cotton fabric imparted an LOI value over 26.

This paper is on the luster property of fertile fabric materials which is one of the important factors related to the development of clothing materials leading to the value-added products. Using several image analysis techniques, the optical properties, especially luster related ones, of the commercially available fabrics were measured and analyzed. The fabric samples included 6 kinds of preliminary experimental fabrics along with 22 kinds of fabric which were commercially available. The images acquired at various observing angles are taken by 44 Points and these Pictures are analyzed into luster through the image analysis program. The preliminary experiment demonstrated the effects of weave types and the number of yarn twist on the luster of the fabrics through the use of the image analysis program.

As the clothing materials have been more functional and advanced, the cotton fabrics for dress shirts or blouses have been more qualified and the sewability for high degree of completion has been required. This study aims to identify the seam strength depending on the change of stitch density of fine cotton fabrics by fabric and thread and so the general seam performance of fine cotton fabrics by analyzing the seam efficiency and breaking mode of seams. For an experiment, 3 kinds of fine cotton fabrics and 2 kinds of threads were selected and the sample was made by changing the stitch density by four steps. Then, the seam strength was measured. Next, the seam efficiency and breaking mode of seams were analyzed on the basis of the results of seam strength measurement. The results are as follows: All fabrics showed the similar tendency in seam strength. The seam strength is related to the tensile strength and thread strength, it increased only to a certain stitch density. When the stitch density exceeded a certain level, fabrics were destroyed or threads were cut. Then, the seam strength didn't increase. Furthermore, the more the seam strength increased, the more the seam efficiency increased. For increasing the maximum stitch density, it was required to use the fabrics and threads which had similar properties, in other words, the high thread strength for the high tensile strength and the low thread strength for the high tensile strength.

This research explored the effects of abrasion, laundering, and abrasion/laundering interaction upon wear of 15 durable nonwoven fabrics. Wear was measured in terms of changes in tensile strength and stiffness. The test materials consisted of nine different dry-laid commercial interfacing fabrics of various fiber contents and six spunbonded poyester and polypropylene fabrics. Three fixed levels of abrasion and four fixed levels of laundering made up the 3$\times$4 factorial analysis used for the experiment and the analysis of variance. Findings revealed that abrasion had a greater effect than laundering on strength and stiffness of the tested fabrics. Laundering seemed related to the particular fibers used and to the fixation quality of fiber bonds. Spunbonded webs performed better than dry-laid webs in retaining tensile strength Stiffness change occurred more readily than strength change. Lighter, flexible, stretchable fabrics seemed less easily abraded than heavier, stiff, less stretchable fabrics. The interfacing fabrics of 70/20/$10\%$ nylon/polyester/rayon blends with high crosswise stretchability effectively resisted wear caused by abrasion and laundering. Further research is recommended to study the effects of longer abrasion periods and additional laundering cycles o,1 wear qualities of nonwoven fabrics. Additional factors such as amount and fixation methods of bonding agents, the effect of shear distortion, seam construction, and drycleaning solvents could also be studied.

A pre-treatment process has been developed for natural dyeing of wool by which the dyed materials have been imparted antimicrobial efficacy against both gram-positive and gram-negative bacteria durable up to 20 washes. In this process, wool fabrics were treated with citric acid under oxidizing condition prior to dyeing. The treated fabrics were then dyed with four different types of natural dye powders obtained from leaves of silver oak, wattle, tanner's senna and flame of forest. All the natural dyes produced yellowish brown colour on wool fabrics. The washing and light fastness properties of the fabrics subjected to pre-treatment were one grade higher compared to those of the dyed fabrics without pre-treatment. The pre-treated wool fabrics showed antimicrobial efficacy against both gram-positive bacteria (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli). The fabrics dyed without pre-treatment showed antimicrobial efficacy against gram-positive bacteria (Staphylococcus aureus) only. The durability of antimicrobial efficacy was higher in pre-treated and dyed wool fabrics compared to the dyed fabrics without pre-treatment.

Textile materials are frequently in contact with surfactant solutions during their manufacturing or finishing processes as well as cleaning processes in use. Liquid wetting, wicking and absorbency of textile materials, and the liquid properties, surface characteristics and pore geometry of textile materials, and the liquie-solid interactions, In this paper, 10 different nonionic surfactants, including Span 20, Twen 20, 40, 60, 80, 21, 61, 81, 65, 85, were used. The surfactants were characterized by their hydrophile-lipophile-balance (HLB) values, structures, and surface tensions. The 0.1g/dL and 1.0g/dL surfactant solutions, which were both above critical micelle concentration (CMC), were used to see the concentration effects on the wetting and absorbency of cotton fabrics. The wetting behavior and liquid retention properties of hydrophobic cotton fabrics with different nonionic surfactant solutions are reported. The contact angles are greatly decreased and the water retention values are greatly increased by adding most of the surfactants studied into the system. The extents of this effects are influenced by the characteristics of surfactants and its solutions. Hydrophilic surfactants which have low number of carbon atoms or unsaturated hydrophobe structures are more effective in improving the wetting and absorbancy of hydrophobic cotton fabrics. The water retention of hydrophobic cotton fabrics has positive relations with $cos{\theta}$, adhesion tension and work of adhesion. The 1.0g/dL surfactant solutions show similar, but slightly improved wetting and absorbency characteristics of hydrophobic cotton fabrics compared to the 0.1g/dL surfactant solutions.

The purpose of this study is to examine and to evaluate the properties of pile materials to produce velvet fabrics which have excellent handle. In order to perform this purpose, the mechanical properties, hand value (H.V.), total hand value (T.H.V.), total appearance value (T.A.V.) of acetate, cuprammonium rayon, cotton materials for velvet as the typical commercial Pile fabric were measured and analyzed by KES-F system. The important results obtained by this study are as follows. 1 For acetate pile, elogational deformation was easy and bending rigidity of weft was high and elastic recovery was excellent compared with the other materials. 2. Cuprammonium rayon velvet was shown that pile bending rigidity and hysterisis were low. Cotton velvet was shown that compressional energy was high and compressinal elasticity was exellent. 3. In the case that specimens were applied by men's winter suit program, H.V was shown that Koshi of acetate velvet was similar to that of cotton. Numeri of cuprammonium rayon velvet was higher than the others and Fukurami values for all of the three fabrics were similar. 4. But in case that specimens were applied by women's winter suit program Koshi of cuprammonium rayon velvet was lower. But Numeri of that was higher than the others and Fukurami for all of the three fabrics were similar and Sofutosa of cotton velvet was lower than the others. T.H.V. of the acetate velvet was the highest in men's winter suit program while cuprammonium rayon velvet was the highest in women's winter suit program T.A.V. of acetate velvet was highest.
