This research investigated the difference in fabric preference over formal wear attire of 1999 Spring/Summer season between Korean and American female consumers. 25 Korean and 25 U.S.A. fabrics were used as fabric samples, and the respondents for the survey included 50 Koreans and 50 Americans in the 20s and 40s age groups. All six population groups showed similar dislike rankings toward the total fabrics (n=50). When the Korean fabrics and the U.S.A. fabrics were considered separately, the 20s and 40s age groups, especially between Korean 20s and Korean 40s, showed significant similarities in the dislike rankings. When the dislike preferences between Korean fabrics and U.S.A. fabrics were examined for different population groups, all the groups showed somewhat similar dislike rankings and in all cases U.S.A. fabrics were disliked more than the Korean fabrics. The most apparent difference in the physical characteristics of disliked fabrics was observed in jabric color. The Americans, especially the 40s age group, disliked fabrics with dark compound colors, whereas the Koreans in all age groups dislike fabrics close to bright pure colors.

This study investigated into the effects of the colors of warp and weft on the overall colors of fabrics, along with the visual changes of colors by the measuring angle of both warp and weft, by means of cross-dyeing of cotton/PET union fabrics. First, the reflectance of polyester is higher than that of cotton over the whole wavelength. Second, the dyeing of polyester uses the disperse dyes and that of cotton uses fiber-reactive dyes, the differences in the features of dyes and the reflectance of fabrics cause the same colors to be perceived different by the angle of observation. Third, the dyeing of cotton and PET fabrics individually with the same color revealed that the dyeing of cotton and PET fabrics in one bath resulted in a small difference in colors between the two fabrics than the separate dyeing in two bathes. In the case of one bath, the dyeing of PET fabrics followed by that of cotton fabrics resulted in a small difference in color than the dyeing in the reversed order. Fourth, when cotton/PET union fabrics were dyed in ten colors, the difference in colors between the two fabrics was small; and due to the difference in the density of warp and weft of union fabrics, some difference was detected in comparison with the results of separate dyeing of cotton and PET fabrics in one bath. The latter did not produce the changes in color which was recognizable with the naked eyes. Fifth, when cotton/PET union fabrics were dyed in ten colors, any color change was not observed by the measuring angle, and the inclination in the direction of warp or weft resulted in the tendency of color-deepening. In the measurement of the latter, the inclination in the direction of weft resulted in the higher color-deepening than that in the direction of warp, due to the influence of weft.

Parsimon juice dyeing is the one of the most popular natural dyeing methods which have been done traditionally among the farmers. The clothes dyed with parsimon juice has several merits, that is, it become much more durable, cool, easy to wash and wear after dyeing and these merits are the reason why people likes to wear the parsimon juice dyeing clothes as work wear. Especially in Cheju province, parsimon juice clothes became a folk costume and many people still enjoy wearing it in the hot summer days. But one of the demerits of parsimon dyeing is that the possible period of dyeing is very short. So, if parsimon juice dyeing could be done with the preserved parsimon juice, it would be possible to enlength the period. With this idea, we compared the color and colorfastness of fabrics which were dyed with 4 kinds of parsimon juice. The experimental parsimon juice 96-8 was preserved during 13 months, 96-9 was 12 months, 97-8 was 1 month and 97-9 was not preserved one. The experimental fabrics were cotton, silk. nylon and polyester fabrics. The results were as follows ; 1. The colors of fabrics dyed with experimental parsimon juice 96-9, 97-8, 97-9 were yellow-red and dyeing states were good. But the colors of fabrics dyed with 96-8 were dark and the state were bad, because the color of experimental parsimon juice 96-8 was changed during preservation. 2. The best state of dyeing could see in the fabrics dyed with experimental parsimon juice 97-8, although that was preserved 1 month. 3. There were differences of color between experimental fabrics dyed with same juice and the colors were thicker in cotton and silk than in nylon and polyester fabrics. 4. During wetting and drying process, the color changes in fabrics dyed with no preserved one were more than in fabrics dyed with preserved ones. 5. The color fastness to the light of the dyed fabrics was over 4, to the acidic perspiration was 3~4 or 4~5, to the alkaline perspiration was 2, 3 or 3~4 and to the washing was 1~2. There was no significant difference in colorfastness between the 96-9 dyed fabrics and 97-9 dyed fabrics.

This study examined the cause of the phenomenon of shrinkage in machine-embroidered fabrics, specifically those made of thin and pliable fabrics. Four woven fabrics and two knitted fabrics were selected as samples for analysis. The fabrics selected were silk organza, flax linen, polyester chiffon, cotton batiste, polyester raschel mesh, and cotton jersey. The thickness and drapability of the fabrics were observed and the shrinkage of the various types of embroidered fabrics produced using satin & step stitch techniques were measured. Moreover, the correlation between the shrinkage of the machine-embroidered fabrics and the drapability of the original fabrics was analyzed. Also, the colorfastness of six embroidery yarns was determined. The results of the study are as follows: first, the shrinkage of machine-embroidered fabrics increased at a greater rate than in embroidered knitted fabrics as compared to rates in embroidered woven fabrics. Moreover, in terms of stitch techniques, there was a greater shrinkage rate when satin stitch was applied compared to step stitch. Second, the shrinkage rate of machine-embroidered fabrics decreased when a stabilizer was fused onto the fabric. The shrinkage rate also decreased for fabrics when fused with paper stabilizer compared to those without it, and the rate decreased at a greater amount with paper stabilizer as compared to alginate film. Third, since there was a strong correlation between the shrinkage rate of the embroidered fabric and the drapability ratio of the original fabric, it was generally the case that the more pliable the fabric was, the greater the shrinkage rate was when the fabric was embroidered. Fourth, while the embroidery yarns mainly used in machine-embroidery presented an overall excellent level of colorfastness, there was slight color migration of level 4 to level 5 when using viscose rayon.

In this paper, the fabrics for Korean folk clothes(KFC) undergoes repeated laundering under given condition. After this cyclic laundering was applied, the mechanical properties of the specimen were measured using KES-F system in order to evaluated the end-use performance of fabrics for KFC. And also, the crease recovery of fabrics for KFC were measured by shirley crease recovery tester. 78 different kinds of commercial silk fabrics and polyester fabrics for KFC were used for this study. The experimental results were analysed statistically to relate the mechanical properties and the crease recovery of fabrics for KFC. Furthermore, these changes in dimensional stability, mechanical properties and handle of fabrics for KFC were discussed in comparison with those values for silk fabrics and polyester fabrics. The results obtained are as follows. 1. Regardless of materials, remarkable increase are observed in shrinkage of the fabrics for KFC about repeated laundering, but dull increase are observed in shrinkage after 10 cycles of the repeated laundering. On the other hand, slack extend are observed in dimensions after 20 cycles of the repeated laundering. The shrinkage of fabrics for KFC after 10 cycles of the lundering showed that the silk fabrics are $1.74{\pm}0.33\%$ (warp direction) and $1.35{\pm}0.23\%$ (weft direction) and the polyester fabrics are $1.45{\pm}0.22\%$ (warp direction) and $1.25{\pm}0.23\%$ (weft direction). 2. Except for tensile property, these changes in mechanical properties of fabrics for KFC by laundering have $\pm$ 16 range of bending, shearing, compression, surface, thickness & weight as compared with before laundering. Particularly, the LT and RT about $1\~3$ cycles of the repeated laundering showed remarkable decrease. And SMD, WC, T & W of fabrics for KFC by the laundering were more increased than one for original fabrics. But B, 2HB, G, 2HG, 2HGS were decreased more than one for original fabrics. 3. 'Stiffness', 'Anti-drape', 'Crispness' and 'Scroop' hand values decrease and'Fullness & softness', 'Flexibility & softness' hand values increase with repeated laundering. 4. Remarkable decrease are observed in crease recoveries about $1\~5$ cycles of the repeated lundering, but slack decrease are observed in crease recoveries after 5 cycles of repeated laundering. The crease recovery of fabrics for KFC have negative(-) correlation with LT, RT, G, RC and MMD, This fact implies that the smaller these values, the larger the crease recovery. The crease recovery of fabrics for KFC has a high degree of correlation with the mechanical properties such as shearing, compression, surface property. And also, the crease recovery are expected by measuring the mechanical properties such as G, 2HG, 2HGS, RC, WC, LC, MIU, MMD and SMD, according to the obtained regression equation.

This study was carried out to improve the thermal insulation properties of wool and wool- like fabrics by treating the fabrics with polyethylene glycol, to evaluate the fabric hand of PEG treated wool and wool-like fabrics and to grade up the fabric hand of the treated fabrics by treating with softening agents. Wool and wool-like fabrics were treated with high molecular PEG-8,000 by PDC. The thermal release/storage properties were measured on a DSC. Hand of specimens were evaluated by KES-FB system. The results were as follows; 1. PEG-treated fabrics showed thermal storage and thermal release properties by DSC and the heat contents were generally proportional to the add-ons. 2. PEG-treated fabrics showed higher Koshi and lower Numeri and Sofutosa values due to lower tensile energy and recovery and higher bending rigidity and shear stiffness as the add- ons increased. 3. PEG-treated fabrics showed much lower bending rigidity after softening agents treatment.

Polyester microfiber fabrics were decomposed at 100, 110, 120 and 140 t of temperature and 0.5, 1.0 and 1.5% of sodium propyleneglycolate/propyleneglycol solution(SPG-PG). Characteristic decomposition feature and physical and chemical properties of the decom- posed PET microfiber fabrics were discussed. The activation energy was 18.77 kcal/mol and the dyeability of the decomposed PET microfiber fabrics was found to be improved as it was supported by the examined K/S values. Up to the 20% of the weight loss of the PET microfiber fabrics, K/S values incresed with increasing the weight loss. The melting temperature of PET microfiber fabrics decomposed by SPG-PG showed no fundamental change. Tensile strength of the decomposed PET microfiber fabrics decreased linearly in accordance with the increased the weight loss of the PET microfiber fabrics. The moisture regain and the tactilities increased in accordance with the increased the weight loss of the PET microfiber fabrics.

This study surveys the physical properties of Solo-spun fabrics related to the characteristics of Solo-spun yarns, which were described in previous reports. For this purposes, 6 kinds of fabrics were woven on the pilot loom. 3 kinds of Solo-spun yarns with the 3 level of twist mutiplier of Nm 1/30 and 3 kinds of conventional ring-spun yarns with the same levels of twist multipliers of the same yarn counts. The fabrics were of 2/2 twill and clear-cut finished. The physical properties were surveyed by means of KES-FB system. Solo-spun fabrics seemed to be stiffer than ring spun fabrics as showing the lower extensibility with higher tensile energy, the higher bending rigidity, and the higher shear rigidity. Solo-spun fabrics showed the lower value in surface friction coefficient and surface roughness. For fabric abrasion tests, Solo-spun fabrics showed the higher pill resistance.

This paper is to study the characteristics of fabrics dyed with astringent unripe persimmon juice. The cotton silk rayon and nylon fabrics were dyed with astringet unripe persimmon juice. The structures of natural fabrics dyed fabrics and dyed fabrics followed by washing were examined by scanning electron mi-croscopy. Surface reflexibility of VIS trans-mittance of UV VIS and NIR were analyzed. The study conclues as follows: 1. Colour of cotton fabrics dyed with persim-mon juice became darkended as a function of exposing time to sunlight. That colour was chaged after washing. 2. Blocking effect of ultraciolet light and visible ray was increased in all dyed fabrics. Especially dyed cotton fabric blocked UV light perfectly and the blocking effect was still remained after 9 washings. 3. Persimmon juice dyeing produced coating effect to fabrics besides dyeing effect accord-ing to the scanning electron micrographs. In a word the cotton fabric dyed with per-simmon juice has blocking effect of UV light stiffness. Therefore I think persimmon juice dyeing is a very useful textile finishing and ex-pect a wide application of the technique in fu-ture.

The experiment was conducted on five different kinds of fabrics dyed with loess. The sewability of fabrics dyed with loess by measuring the maximum needle piercing forces(MPF) through fabrics has been studied, MPF measurement using tensile tester was done 60 times for each fabrics at fixed low speed of 300mm/min. The nature of the loess on the dyed fabrics was physically jammed betweenthe fibers or adhered to the surface of fibers in the form of the fine particles so that the MPF through fabrics increases extremely in proportion to the increase of loess uptake and the plying number of fabrics dyed with loess. This results indicate that the MPF through fabrics is affected by mean value of the coefficient of friction on the surface of fabric(MIU) and cloth cover factor(Kc) in this experiment. Fabric was finished with softner to decrease the MPF during sewing operation, The MPF through softner finished fabric was decreased remarkably.
