What is RETEXPET?
RETEXPET is a 100% recycled fabric made from discarded clothing and PET bottles.
It is a polyester fabric created by partially recycling collected clothes that are no longer wearable and mixing them with recycled PET bottle materials.
U-DAY proposes environmentally friendly products by recycling them as umbrellas, as an initiative to reduce clothing waste and promote decarbonization.
Used polyester clothing and discarded PET bottles are collected.
*Clothing refers to domestic discarded polyester clothing collected at cooperating factories in Japan.
At a factory in China, pellets from discarded clothing are mixed with recycled PET bottle material pellets.
This results in "RETEXPET," an original fabric made from 100% recycled materials.
10% recycled fiber material + recycled PET material = 100% recycled polyester.
