According to the Chronicles of the Three Kingdoms (Koguryo, Paekje, and Silla) and other old documents, Korea had an advanced technology of weaving ramie cloth and exported it to other countries already in the middle ages.

Ramie cloth, well known as a special product of Korea, is as stiff as starched one and makes people feel cool.

It is used with and without bleach.

The durable and fadeproof cloth is not easily wet with sweat, so it has been taken for summer dresses from old times.

The production of ramie cloth is based on modern technologies in the country.
