In this research, the silk web was hot-pressed for various times, the effect of press time on the structure and mechanical properties of silk non-woven fabric was also investigated. The yellowing appeared in the silk non-woven fabric and became more apparent as press time was increased. The crystallinity of silk was decreased by the hot press treatment and it did not change significantly with an increase of hot press time. The porosity of silk non-woven fabric was constantly decreased until 120 s and it did not change much after that. The thickness of silk non-woven fabric was significantly decreased by a press time of 10 s and slightly decreased with a further increase of hot press time. The hot press treatment increased the maximum stress and elongation of silk non-woven fabrics. The press time had a significant impact on the mechanical properties of silk non-woven fabric, with 90 s being the optimum condition for the best work of rupture of silk non-woven fabric.

This study is about the fabric attached to the relics excavated from the Shimchun-ri tomb of the 4th century and the Moonsan-ri tombs of the 5th century. We studied 5 pieces of fabric from the Shimchun-ri tomb: one piece was silk and the other four pieces were hemp. We were able to observe 8 pieces from the four tombs in Moonsan-ri, All of them except one ramie were silk. The two kinds of bast fiber found in the tombs of Shimchun-ri and Moonsan-ri were hemp and ramie, and they were found to be plain woven with S-twist thread which thickness is uneven. The density was more fine compared to the hemps found in the Kaya or Shinra tombs of the similar era. All of the silk textiles found in the Shimchun-ri and Moonsan-ri tombs used non-twisted thread, and were plain woven. Also, we found degummed and raw silk from the tombs. The average density of the silk textiles from these tombs are similar to other areas of the same time, and studies show that they used non-twisted thread in plain woven silk found in other tombs. Therefore, we can conclude that they usually used non-twisted thread when producing silk textiles.

The purpose of this study is to help to prevent daily noises by measuring the noise absorption coefficient of the non-woven fabrics and wallpapers which are commonly used in lining and noise absorption coefficient of lining curtain. Seven types of fiber materials for the interior decoration, one non-woven fabric for the wallpaper linings, and two types of textiles for curtain linings are used as the experimental materials in this study. The noise absorption coefficient of the noise absorbents were measured by using impedance tube. And the thermal transmittance were measured by using thermal transmittance tester. The results of this study are as follows; Observing the noise absorption efficiency of each experimental materials, the combination of fiber materials and linings, the noise absorption efficiency of cotton, polyester and silk were similar and for the experimental materials of flax, rayon, acrylic and nylon were resulted the similar noise absorption efficiency. The result of combination of fiber material and black fabric was highest among the combined linings. For the combination of fiber material and non-woven fabric, double layers of non-woven fabric resulted slightly higher noise absorption coefficient result than single layer of non-woven fabric. The thermal transmittance and the sound absorbents of experimental materials were affected by the thickness, density and layer of air of the experimental materials.

This study is to examine the characteristics of fabrics in Koryo dynasty by reviewing the fabrics for enshrining oblations inside a buddhist statue in MoonSoo temple, which are currently possessed in SooDuk temple. The research results follows : The fabrics are 33 pieces in total : 28 Pieces of normal fabrics, 5 pieces of fabrics that is used for covering the five grains, and others like variegated silk threads. Out of 33 pieces of fabrics are there 31 pieces of silk and 2 pieces of ramie. The tabby fabrics, which have the most pieces among the fabrics, are 11 pieces in total. There are 1 piece of designed tabby fabri. whose patterns are expressed by dyeing. as well as non-designed tabby fabric. The twill fabrics are 8 pieces in total. Its patterns are mainly the type that small patterns are consecutively reiterated. And they have various patterns including plant patterns, such as lotus pattern, flower pattern. etc., animal patterns such as dragon pattern. etc., geometric patterns. such as turtoise-shell pattern. swastika, etc. The leno and gauze fabrics are 1 piece of 4-end complex designed-gauze and 1 piece of gill gauze. The compound woven fabrics are 2 pieces of brocaded gauze and 3 pieces of brocaded twill. Brocaded gauze is a kind of brocaded fabrics and is made by adding a gold thread between wefts of already weaved gauze. The figured fabrics are 1 piece of tabby fabric, 6 pieces of twill fabrics, 4 pieces of leno and gauze fabrics, and 5 pieces of compound woven fabrics. All of them are 16 pieces out of all 33 pieces and amount to almost 50%. Single-patterned fabrics, that is one pattern is expressed individually, are much more than any others. Plant patterns are the ones that are used the most.

This study was carried out to investigate the characteristics of the soluble sericins after degumming and after hydrolysis of insoluble sericin with various enzymes. Physical and chemical characteristics of the soluble sericins were also studied and pack test was conducted. Electro donating ability of the various sericins became higher as high＞low＞KP＞PP＞PA. In FT-IR analysis, the band of insoluble sericin at 3,285cm$\^$-1/ was shifted to the lower wavelengths in soluble sericins. The intensity of the amide II band was reduced and shifted to lower wavelengths as a result of hydrolysis. In DSC analysis, all sericins showed endothermic peaks around 200$^{\circ}C$ and insoluble sericin showed another peak at 250$^{\circ}C$. The endothermic peak of the insoluble sericin was found at higher temperature compared with those of the soluble sericins which showed at 300$^{\circ}C$. Whiteness of the various sericins became higher as low＞high＞PP＞PA＞PK＞IN and yellowness were PK＞PA＞PP＞low＞high. In pack test, the skin packed with the non-woven fabric treated with the various sericins was more smooth and less oily.
