～Silk that cuts carbon dioxide emissions by 3 kg per suit～
Yugen Co.,Ltd, organizer of JTEX, a trade organization dedicated to international markets, is pleased to introduce NecoS (Nagahama Ecology Silk), a silk material developed by Yoshimasa Orimono Co.,Ltd, at "the International Sustainable Fashion Expo Autumn".
NecoS reduces carbon dioxide emissions by 3 kg per suit, compared to a silk suit produced using conventional methods.
With the globalization of the supply chain, there is a growing awareness that the textile industry is one of the most concerned with sustainability in terms of waste, water and energy consumption, pesticides, plastics, working conditions and human rights. Through the development of NecoS, we hope to contribute to reducing the use of resources in the fashion supply chain.
- Dates: 18 (Mon) - 20 (Wed) October 2021 (3 days) 10:00 - 17:00
-Venue: Tokyo Big Sight, West Exhibition Halls [A2-40].
- Featured Product: Sustainable silk fabrics from Yoshimasa Orimono Co.,Ltd.
NecoS [Nagahama Ecology Silk]: Chirimen crepe produced with a chemical-free degumming process.
The innovative NecoS technology reduces carbon dioxide emissions by lowering the amount of water and heavy oil consumption, while reducing the need for soda ash.
A patent application has been filed for this technology along with Shiga Prefecture.
By eliminating the use of soda ash, carbon dioxide emissions are reduced by 8.7 kilograms per 200 square meters of normal degguming volume per batch.
It also reduces the use of water and heavy oil. By replacing boiling water with room temperature water for the pre-treatment and finishing process, the carbon dioxide emission is reduced by another 93 kg.
Thus, the total reduction in carbon dioxide emissions is 101.7 kg.
In addition, the method also makes it possible to cut down on:
・Water: 2,000 liters
・Heavy oil: 17 liters
・Soda ash: 22 kg
These figures were calculated by the Northeast Industrial Research Center of Shiga Prefecture, based on the "Guidelines for Regional Global Warming Plans" and the "List of Calculation Methods and Emission Factors for Greenhouse Gases" of the Ministry of the Environment (https://ghg-santeikohyo.env.go.jp/files/calc/itiran_2020.pdf).
The journey to the development:
Silk fabric is made using a process called "degumming" to remove sericin, the natural protective molecule of silk yarn. Sericin is also used in cosmetics. In the conventional method, we applied hot, slightly alkaline water from Lake Biwa. In the past, we used to use the water as if it were unlimited. But when we finally realized what was at stake, we decided to take action.
It was very challenging to go back to the ancient method, because of the costs and the way to implement it in mass production. But we finally succeeded in commercializing NecoS last year. The production volume is still limited, but we have already started selling it in Europe, where sustainability is considered one of the priorities.
Since it is made without any bleaching agent, you can fully enjoy the natural shine, beauty and touch of silk.
～Message from Kazuo Yoshida, President ~
I am Kazuo Yoshida, president of Yoshimasa Orimono Co.,Ltd, a textile manufacturer that has been operating for 95 years in Nagahama. As a weaving manufacturer from a small town, we have worked hard to maintain our business despite the current difficult market situation. In recent years, we have begun to actively engage in sustainable development initiatives. To be honest, the more I learn about sustainability, the more I realize how difficult it is to put it into practice. However, we have met a number of people and stakeholders who share and support our company's initiative along this journey.
We would like as many people as possible to see what a small company like ours has accomplished so far. We also hope to hear the comments and opinions of visitors.
We’re looking forward to seeing you at the exhibition in Tokyo, from October 18.
