LINEN - Pretreating, dyeing and finishing fla

Linen, also known as flax, is one of the oldest agricultural crops of mankind. Already 5000 years ago Egyptians bedded the dead on linen cloth. The Romans too cherished linen and called it “linum usitatissimum“ - the very useful linen.

Industrialisation, the development of synthetic fibres, agricultural policy, structural changes in agriculture, the explosion of labour cost and much more made the demand for this natural plant drop steadily. In 1956 flax cultivation was ceased completely in the Federal Republic of Germany.

However, in the 1980s, flax cultivation was supported again, due to a wheat surplus in the EC.
