In the part 1, relations were found between fundmental mechanical properties and primary hand values, performance of Korean women's summer fabrics. In this paper, in order to investigate the hand values and mechanical properties such as tensile, shearing, bending, compression, surface and thickness & weight of the women's fall & winter fabrics were measured by KES-F system. Sorts of 90 commercial fabrics for women's fall & winter clothes were classfied into 39 silk and 51 polyester fabrics according to meterials. The experimental results were analysed statistically to relate the hand values and the mechanical properties and concerning to formation of weared clothes and transformation behavior were investigated. Furthermore, there mechanical properties as well as their hand values were discussed in comparison with those values for kimono fabrics. The main results are summarized as follows; 1. The shape of silk fabrics in formation for weared clothes show a box-shaped silhouette. Polyester fabrics has a easy to shape-less and make a silhouette which goes along with the body. 2. Silk fabrics for Korean women's fall & winter clothes have ${\pm}1\sigma$ range of bending, shearing, surface properties and thickness as compared with kimono fabrics. 3. A wrinkle recovery and drapability of silk fabrics for Korean women's fall & winter clothes are inferior to kimono fabrics. On the other hand, the fabrics for Korean women's fall & winter clothes have conical-shaped silhouette based on higher bending rigidity. 4. Except for flexibility with soft feeling, a primary factor of mechanical properties contributes to the hand values of fabrics for Korean women's fall & winter clothes having no concern with materials were same as the women's summer fabrics. 5. As for the hand values of fabrics for Korean folk clothes, stiffness, anti-drape stiffness are larger than those of kimono fabric and stiffness, anti-drape stiffness, crispness of fabrics for Korean women's fall & winter clothes have smaller values as compared with Korean women's summer fabrics.

Haptic systems have been widely used for both virtual reality and augmented reality application including game, entertainment, education and medical sectors. Clothing designers and retailers initiated using AR and VR technologies to help the consumers find style with the perfect fit. Most of the developed augmented reality shopping is implemented by overlapping the image of the clothes on the customer so that he/she can find the fit. However, those are only visual information and the customer cannot experience the real size and the stiffness of the clothes. In this paper, we present the haptic upper garment which provides the haptic feedback to the user using cables. By controlling the length of the cable, the size of the clothes is set and by stiffness control, the compliance of the fabric is implemented. The haptic garment is modeled for precise control and the distributed controller architecture is described. With the haptic upper garment, the user's experience of the virtual clothes is greatly enhanced.

The shearing properties, which belong to the mechanical properties of fabrics, are most closely related to the appearnace of weared clothes, formation and feeling of wearing. And they are the elements which show the sense of touch, the properties of drape, folds and recoveryk curve foring, and keeping up formation. Sorts of 156 commercial skil fabrics and polyester fabrics of Korean make for women's cloth were tested for shearing propreties. All samples were classified into for summer and for fall and winter wear. Then shearing properties were measured by kawabata's evluation method. In this study shear stiffness(G) and shear hysteresis (2HG, 2HG5) of shearing prperties were measurd, then G/W and 2HG/G which are concerning to formation of weared clothes and trnsformatio behavior wre properties. The results obtained are as follows: 1. Silk fabrics were higher than polyester fabrics in G and 2HG. Thickness and weight of the fabrics for summer were a third to a half of those of the fabrics for fall and winter, but shearing properties were almost the same in the two types of the fabrics. 2. Fabrics for fall and winter were lower than fabrics for summer in G/W and fabrics for summer were lower than fabrics for fall and winter in 2HG/G. 3. korean women's silk cloth was much lighter than Japanese kimono cloth in weight but thickness and shearing properties were almost the same in the two types of the clothes.

Unripe indigenous persimmons which contain rich tannins have been used as natural dye materials traditionally and have been using continuously for dyed clothes named Gal-ot in Jeju. Those persimmons were cheap and easy to use as dyes because of inedible and widely cultured in Korea. Persimmon juice dyes not only make fabrics brown-color but also give functional and hygienic properities such as stiffness, air ventilation of clothes, antibacterial activity, protectivity against ultraviolet light. However there are several serious problems which are ristriction of dyeing periods, longtime irradiation, uneven color and low color fastness etc. in persimmon juice dyeing. This study purpose to improve dye effect and method in order to enlarge useability of persimmon juice dyeing. Cotton fabrics were pad-dyed to 100% pick-up using padding machine after dipping in persimmon juice extracted from unripe persimmons indigenous from Jeju. It was possible and available to control pick-up rate. The color of dyed cotton fabrics by padding method was more even and repeatable than which by traditional hand method. Persimmon juice concentrations were 4 types of 10, 25, 50 and 100％. The more concentration increased, the more color deepened. UV Irradiation instead of sunlight was applied to color developing. Irradiation times were shortened till 1∼8 hrs. Same color values could be taken without water wetting which were required in sunlight irradiation. Tensile strengths of cotton fabrics pad-dyed with low concentration of persimmon juice decreased but recovered at high concentrations. Elongations(％) of cotton fabrics pad-dyed with persimmon juice were increased 1％ more than undyed cotton in sunlight irradiation. Drape stiffness increased upto double times as much as.

Silk organza can make the silhouette of clothes bulky and rich, owing to its stiffness. And silk organza in the gum has better dyeability so can be dyed more bright and deeper color than scoured silk because silk organza has sericin gum that has better dyeability than fibroin. So, silk organza came into the most broad use as the material for Hanbok, especially in summer. But the silk organza has poor color fastness. Sericin is removed from organza when silk organza go through scouring. The purpose of this research is to find out the optimum conditions that the scoured silk fabrics can get stiffness by persimmon juice treatment. For experiments, non scoured, partially scoured and fully scoured silk fabrics were prepared by alkali treatments. Then 3 kinds of silk fabrics were treated with the concentration of 1, 5, 10, 50 and 100% of persimmon Juice. The change of fiber surface of the various silk fabrics were observed By SEM. The hand values of those fabric samples also were measured hand values by Kawabata Evaluation System and stiffness by Cantilaver method. By scouring, the silk organza got more flexibility and less cohesiveness between their fibers. And it can be a little more bulky by removing gum. Namely, silk organza lost its unique stiff and crisp handle. By the persimmon juice treatment, tannin component could be coated on the fiber surface. so that the stiffness of the fabrics were improved.

There are two standards for evaluation of fabric aesthetics, the feeling of fabric and the fabric sense of sight. Its drapalility with lustre is one of factors to decide the fabric sense of sight. This study was carried out to investigate the drape property property of fabrics. The fabric characteristics and the physisical properties of fabrics were tested. And the effect of the laundering on the drape properties was examined. RESULTS : 1. The drape coefficients of sampled fabrics were increasd as the thickness of fabrics were increased, excluding the fabric consisting of 60% polyester$\times$40% wool. 2. The drape coefficient of sampled fabrics were decreased as the cover faders of fabrics were increased, excluding the summer clothes and the fabrics of 100% wool. 3. The drape coefficients of fabrics other than sumer clothes were increased as the weight of fabrics were in creased. 4. Positive correlation was observed between the stiffness and the drape coefficient. 5. Negative correlation was observed between the fabric shrinkage and the drape coefficient. 6. The drape coefficient was decreased to a certain limit by laundering.But as the laundering was repeated up to certain number, the drape coefficient and the node number, a significant correlation was observed between the drape coefficient and the node shape.
