The long-awaited SILK is born


The developer of SHIDORI, Sankaseiren (山嘉精練) is a silk processing company established in 1970. It has specialized in degumming, dyeing and other additional processing for the silk from all over the world. The family has been famous for a long history of engagement in the Japanese silk industry, since the first generation ancestor Iseki Sorin started to make textile and crest in 1555 at Kyoto. The adventure spirit and the traditional technique have been preserved for more than 450 years in the family. The “Single dying bath” adopted by the company would enable the reproduction of a specific color anytime upon request. The pigments used in coloration would not induce any damages to the fabrics while maintaining a high colorfastness. And the degumming method is also precisely designed to fit with the above processes. Sankaseiren constantly strives for improvement by research and development of new technology. It is the silk expert aspires to enhance and preserve the traditional techniques in the industry.

About the environment

Sankaseiren was founded in 1970 in Kameoka Kyoto, a place also called Tamba where is known for the rich natural resources. The land is blessed with various kinds of Japanese famous agricultural products such as chestnut, Matsutake Mushroom and black beans. And this implies a high quality of water and fertility of soil in the area. The factory is situated in such a spectacular natural environment with many surrounding fields and farmlands. Our facilities have operated for more than 40 years in the district, while we have never received any complaint from the nearby farmers and residence. It is a proof of our strict control of the processed water and heavy oil. Although we practically own the land of our facilities, we consider ourselves merely the temporary users of the place in the current time space. In our ideology, we borrowed the land from the nature, and therefore we will have to return the land in its original conditions. With our sincere gratitude for the blessings of the nature, we will safeguard the quality of the water, the air and the land in the region and maintain harmony with local people.
