Partially plant-based polyester workwear arrives in Japan

28/03/2014
Japan-based workwear manufacturer Midori Anzen is launching a workwear collection made from Toray’s ecodear PET, a partially plant-based polyester fibre, which they say is the first in the world to adhere to new BIO-PET Criteria set out by the Japanese government.

Midori says it will start marketing the Plantex series from autumn-winter 2014 season and expects sales of 300 million yen ($3 million) from these products in the first fiscal year and 3 billion yen ($30 million) in three years.

Ecodear PET is a polyester fibre which is produced by polymerising petroleum-based terephthalic acid (TPA) and plant-based mono-ethylene glycol (MEG) made from bio sources such as sugar cane.

The plant-based polymer’s content is approximately 30% of the polyester. Toray positions ecodear PET as its next-generation core product which will contribute to solving global environmental issues - including the depletion of finite resources used to make plastics and some man-made fibres.

The BIO-PET Criteria are official green purchasing criteria for plant-based non-biodegradable synthetic fibre products.

Toray is currently working on developing fully plant-based polyester, with the target of it being in production by 2020. See the latest edition of WSA for a look at the 'bio' textiles market.
