The ancient 'sacred cloths' of Indonesia have diverse characteristics. The purpose of this study is to analyze the characteristics of ancient Indonesian textiles, focusing on 'sacred cloths.' The research is divided into two parts. The first part analyzes the creation period, religious importance, region where the cloths are found, and color of the 'sacred cloths.' The second part focuses on the textile-making techniques and the ritual patterns of the 'sacred cloths.' This research is the second paper. This research analyzes 225 Indonesian sacred cloth examples chosen for their religious function in ceremony, and reviews 10 books and 8 research papers. Field research was done in the Museum of Bali, the Indonesian Museum of Textiles, and nine weaving production houses in eastern Bali. Indonesian sacred cloths express their cultural philosophy and function through production techniques, colors, techniques, and visual patterns. The 'sacred cloth'-making techniques are classified as Batik, Prada, and Ikat. The regions that contribute to the textile production determine what patterns show up on the cloths. Sumatran patterns are philosophical, lavish, and prestigious. Bornean patterns are barbaric and prestigious. Balinese patterns are complex, decorative, warm, festive, calm, and aristocratic. Javanese patterns are symbolic and repetitive. Celebes patterns are artistic and simple. Nusa Tenggara patterns are symbolic and narrative. The forms shown on the textiles, whether geometric, human and animal, natural objects, or abstract patterns, determine how to classify the varied patterns. As a result, ancient Indonesian sacred cloths characteristics portray Indonesian identity as Bhinneka Tunggal Ika(Unity in Diversity).

This research developed a smart girdle for adult women in their 20's that has an inserted carbon weaving heater to help with relief from coldness and abdominal disease through the thermal insulation effect. A pocket of powernet fabric was attached to the inside of the girdle for the easy insertion and separation of the heating device, while the heating device was fixed to a mesh material by cotton yarn and was wrapped with elastic lining material to prevent the mechanical devices from being exposed. A set of 3 hooks was attached to the center of the back of the heating device in consideration of convenience and mobility. Whereas the switch was inserted into around the right waistband, and the battery into the inner pocket around the waist, to integrate the heating device with the girdle. The satisfaction and usability of the fabricated smart girdle was verified by having research participants wear it to evaluate the appearance change caused by the device, the inconvenience of wearing/unwearing, mobility, and the satisfactory functionality of the device. As a result, the grand mean was evaluated to be high, with appearance (4.19), mobility (4.17), and functionality (4.51) being higher than 4.00; which indicates that the heat generation function of the smart girdle is effective. It may be said that such collection and analysis of data that reflect users' opinions have value and significance in that they can be grafted onto future research on new technology as well as they contribute to taking a step forward in the rapidly increasing research of smart clothing, with the new-type clothing equipped with new function.

Hwangnamdaechong Tomb (The 98th tomb in Hwangnam-dong), one of the royal tombs located around the area of royal tomb of King Michu in Hwangnam-dong, Gyeongju, is currently designated as Historic Site No. 40. It is assumed that Hwangnamdaechong Tomb is a royal tomb of the early 5th century. This study aims to examine the fabric relics excavated from Hwangdamdawchong Tomb and currently housed in Gyeongju National Research Institute of Cultural Heritage. The types of fabrics excavated from Hwangdamdawchong Tomb include plain silk, warp-faced compound woven silk, and hemp cloth. Most of these fabrics are adhered to metal products that became rusty. Plain silk found in Hwangnamdaechong Tomb can be divided into four types by its weaving method. Geum excavated from Hwangnamdaechong Tomb is typical Gyeong Geum that uses colored warp for its base and pattern. It is plain Gyeong Geum that the binding weft and warp is plain woven. Although there are a lot of Gyeong Geum fabrics whose colors are hard to define due to yellowing after long years, there are still many fabrics whose color such as purple, red, blue, and green can be identified. As literatures have shown that p cloth as well as silk were frequently woven during Silla dynasty, tremendous amount of hemp cloth was excavated. Most of the hemp cloth has S-twist in the warp and 8-12 seung degree of delicacy.

Some of historical textiles were analyzed to identify the imprinted textures on the metal remains of Haengyeup(a horse strap pendant) and Doja (a knife), which were excavated in the ruins of Hwangsung-dong, Kyungju city in the fifth century and textiles imprinted on the human bones that were excavated in the Pungnae 4th Area, Namyangju county in the sixteenth century. The results analyzed arc as follows ; It was confirmed that the imprinted textures of Haengyeup and Doja are white ramie since the structural characteristics of cellulosic bast fibers, partially projected long oval cross sections with large lumens and the imprinted textures of human bones are silk fabrics since the triangular cross sections of fibroin is showed. All of the textiles were designed in plain weaves. In the case of weaving yarns, the warp threads were thicker than the weft threads, that is, the imprinted textures of Haengyeup were measured by 1.35 mm for warp and 1.21 mm for weft, and the Doja by 1.16mm for warp and 1.11 mm for weft. In connection with the direction of the yarn twist, the Z-twist were observed in the imprinted textures of human bones, whereas it presented the S-twist in the case of Haengyeup and Doja. The warp yarns were mostly harder twisted than the weft yarns on the amounts of twist, that is, it was observed that the case of Haengyeup were amounted to 0.33 twists per centimeter for warp yarns and 0.25 twists per centimeter for weft yarns. Also it was showed 0.32 twists per centimeter for warp yarns and 0.26 twists per centimeter in the case of the textures of human bones. On the fabric counts, it was showed that the finer the yarns the higher the densities since it were $4.3{\times}5.1$ threads per sqaure centimeters and $7.6{\times}7.1$ threads per sqaure centimeters each in the case of Haengyeup and Doja, whereas it was $18.2{\times}33.7$ threads per sqaure centimeters in the case of the textures of human bones.

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.
