Polyester and nylon strings for the koto, a traditional Japanese string instrument, are popular in Japan because of their strength and affordability. However, many players prefer silk strings because of their elongation and tone. We have been attempting to develop highly durable silk strings by using original Japanese silkworm races. Here, we studied the physical properties and durability of silk strings made from the various cocoons. We found significant differences in the physical properties and durability of the strings from different races, including ‘Koishimaru’ and ‘Platinum Boy.’ (E-mail: shimizu@silk.or.jp)

本研究では,明治,大正,昭和期における68点の技術資料を精査して煮繭・繰糸温度の変遷および原料繭の特性のパラメータの解析を行い,各時代における改変要因の分析を行った.その結果,煮繭・繰糸温度は,明治前半期に大きなばらつき幅がみられ,1900年頃以降は高温に収束し,総じて上昇傾向で推移していた.ばらつき幅が生じた要因は,明治前半期の原料繭は繭層が薄弱で品質が低く,繭乾燥技術等も未発達であったため,官営富岡製糸場の起点温度より低温煮繭・低温繰糸の3象限に多く分布し,高温煮繭(若煮),浮繰り繰糸を行う1象限と4象限にも一定数が分布したことにあった.1900年頃以降は繭乾燥技術の進展等によって高品質繭の割合が増加した一方,低品質繭等も高い割合が維持されたため,能率に特化した生産目的が継続され,大正期には原料繭の品質向上によって品位重視に転換した.その結果,高温煮繭(1・4象限)への収束がみられたと推察した.

Tyrian purple (6,6′-dibromoindigo) is the oldest known dye, and has been used since pre-Roman times in the Mediterranean region. In its reduced form in a vat, it dyes fibers a brilliant violet. Although this dye is stable in the solid state, the leuco-form used in vat-dyeing is unstable in light, giving leuco-indigo by debromination; fibers then become dyed a bluish shade. We examined how to prevent the influence of light on this dye in the vat. We found that light of 300-500 nm wavelength promoted debromination, and that good vat-dyeing could be achieved by excluding light of such wavelengths.( E-mail: sawada@ge.meisei-u.ac.jp)

絹の強度はタンニン酸処理により増加する。これは絹の非晶領域に吸着したタンニン酸が分子間結合を促進するためである。しかし、鉄媒染を施した絹の強度は処理液による分子鎖切断のため低下する。

Animal welfare in the fashion industry has been discussed actively in recent years. In fact, because of doubts about the necessity and propriety of the killing of animals during production processes, a movement to avoid animal materials such as fur has emerged, especially in Western countries. Simultaneously, consciousness about animal ethics, including animal rights and animal liberation movements, has activated discussions worldwide to reconsider the human–animal relationship.This paper presents a review of the history of animal welfare and animal ethics development. Then issues involved in these discussions are considered. Specifically, the anthropocentric mode of thought which accompanies the view of animals with clear separation between humans and animals is pointed out, along with the fact that discussion of the human–animal relationship itself does not include practical activities.Additionally, to develop these discussions comprehensively in the future, this discussion specifically examines the Kuyō spirit of producers who witness the killing of animals. Finally, based on the discussion presented above, the future of animal welfare and animal ethics in the silk industry are explored.

The author conducted a restoration study of the 18th-century French court costume and is studying aesthetic sense and dyeing technique. Because costumes are being restored based on detailed research data such as composition data such as costume patterns and weaving techniques, weaving methods, etc. There is no previous study mentioning the reason such as silk costumes are lightweight. In this study, from the survey of textiles in the Rococo era of domestic and overseas museums, it was hypothesized that the texture properties of this court costume texture might be related to silkworm varieties, and for four years from 2012, after obtaining the Grants-in-Aid for Scientific Research, we restored court costumes from breeding of the original race of European silkworm variety. First of all, we bred Sevenne white of European silkworm cultivar, reeled the raw silk, weave a white cloth and made a dress. Next, again breeding it, restoring the fabric of Kasuri made of natural dyestuffs, making it into a court costume.These studies demonstrate that the characteristics of the court costume ‘light, three-dimensional form, and soft’ properties are attributable to the characteristics of the European silkworm cultivar Sevenne White, and due to differences in silkworm varieties. We clarified the importance of fiber properties and the aesthetic sense required in the Rococo era. The characteristic is clearly to have them as a result of the experiment, it became clear that the difference in the form of the dress is caused by the fiber characteristics of the silkworm variety.

Aqueous solution of calcium chloride (CaCl2) is a promising solvent for biomaterial like silk fibroin, thereby offering potential application in industrial purposes. We observed that the silk, produced by larvae of hornets (Vespa), dissolved in an aqueous solution of CaCl2 in the concentration range of 3-6 M. The solubility of hornet silk was the maximum when CaCl2 concentration was 4.5 M. The rate of dissolution of the hornet silk in the aqueous solution of CaCl2 was sensitive to temperature. The hornet silk was found to dissolve in 4.5 M CaCl2 solution even at 20°C. Such high solubility of the hornet silk in the aqueous solution of CaCl2 could be attributed to the low content of β-sheet structure. The silk dissolved in the aqueous solution of CaCl2 within 1 h when the temperature was between 40 and 80°C, and less protein degradation occurred under the aforementioned condition.

The results of this study were obtained from an investigation of the archives of silk production in relation to the tax on silk during the Nara period in the 8th century. The silk producing districts ranged from the Kanto region to Shikoku and Kyushu, and there were over 40 silk producing districts in the middle of the 8th century. Three main kinds of silk were produced, namely Ashiginu fabrics, silk fiber and floss silk, and there were 15 districts producing Ashiginu fabrics (42%). The districts producing the largest amount of silk annually were Echu (floss silk), Inaba (Ashiginu fabrics, silk fiber and floss silk) and Iwami (floss silk). The districts that were the largest annual producers of the three different types of silk were Mikawa (Ashiginu fabrics), Inaba (silk fiber) and Echu (floss silk). Mulberries were cultivated in Echu district in 759 A.D. and this was the only example of mulberry field cultivation in the Nara period. Two hamlets in the Echizen district in 740 A.D. were the only locations where sericulture was practiced in the Nara period. These were produced against the tax of silk by Ashiginu fabrics and floss silk. And the weights of these products were 2.4 and 1.8kg, respectively, and the used cocoon weights were 40 and 30 kg, respectively, from a trial calculation for harvesting cocoons. Moreover, the total harvesting cocoon were about 80 and 90 kg by addition to Ashiginu fabrics. (E mail: mutsuo_miki@yahoo.co.jp)
