Used for sustainable fashion

Types of eco-friendly materials

There are many different types of eco-friendly materials used in sustainable fashion.

■ Natural fiber

  • Organic cotton

Organic cotton, which can be said to be a representative of sustainable natural fibers, does not use any chemical fertilizers or pesticides until harvest.

Organic cotton cultivated by the correct farming method has undergone strict GOTS certification and OCS certification. When purchasing Sustainable Fashion items, please check for the certification mark.

  • Color cotton (natural coloring)

When you think of cotton, you might think of it as pure white, but in reality, many cottons are bleached and colored. For this reason, the original brown and green colored cotton, which is not bleached or colored, is often incorporated into sustainable fashion items as a sustainable material.

  • wool

Wool is so-called wool, and there are about 40 types such as the finest merino wool, blackface, dorset, southdown, and Cheviot. The most commonly used is merino, which is known for its softness, durability and functionality that you can feel on your bare skin.

Wool fiber is well known as an eco-friendly material because when it is discarded, it slowly releases valuable nutrients to the earth and naturally decomposes in the soil over several years.

  • linen

It is a thread or cloth made of fibers called "flux" that can be obtained from the bast of flaxaceae plants. It is cultivated mainly in Russia and France, and because it dislikes continuous cropping, it is planted only once every six years on the same farmland.
In Japan's quality label, only linen and ramie can be labeled as "hemp".

■ Plant-derived chemical fibers

  • Lyocell (Tencel)

Lyocell (Tencel) is made from eucalyptus wood pulp.

  • Modal

Modal is made from beech wood. Although the raw material is wood, it is twice as soft as cotton.

  • Cupra

Cupra is made from the 2 to 6 mm downy hair that is not originally used as a fiber, which is attached to the circumference of the cotton seeds after the cotton is collected.

■ Recycled PET fiber

  • PET

PET, which is a type of polyester, is an abbreviation for "polyethylene terephthalate" and is a fiber made by recycling PET bottles.

KoH T, a sustainable fashion brand, mainly uses cupra, rayon, modal, cotton, wool, silk, linen, paper yarn (Oji Fiber OJO +) and other eco-friendly fabrics to make items. ..

Environmental destruction in the fashion industry

Eco-friendly materials for the environment

The use of eco-friendly materials for sustainable fashion items is environmentally friendly. What is the environmental destruction that is regarded as a problem in the fashion industry?

■ Emission of carbon dioxide during the production of synthetic fibers When manufacturing chemical fibers, a large amount of carbon dioxide is emitted.

■ Working environment of people who produce materials Items sold at low prices, such as fast fashion, are required to be cheap in terms of materials, material production, and wages. As a result, the working environment deteriorates, such as hiring people who produce materials at low wages and using chemical fertilizers and pesticides to save time and effort in cultivating materials.


■ Emission of greenhouse gases by transportation between production plants By transporting materials produced at low cost in developing countries to factories that can manufacture at low cost, greenhouse gas emissions will increase. Also, when the finished product is shipped from the country of manufacture to the world, a lot of greenhouse gases are emitted.
