Linen Fiber

It is strong, durable, and resists rotting in damp climates. It is one of the few textiles that has a greater breaking strength wet than dry. It has a long "staple" (individual strand length) relative to cotton and other natural fibers.

Production History of Linen

Up until the 1950's or so the finest linen yarn was made in Scotland, Ireland, and Belgium. The climates of these locations were ideal for natural processing methods called "retting". As years went by many of the finest factories in those areas closed, and most linen is currently made in China.
The decrease in use of linen may be attributed to the increasing quality of synthetic fibers, and a decreasing appreciation of buyers for very high quality yarn and fabric. Very little top-quality linen is produced now, and most is used in low volume applications like hand weaving and as an art material.

Uses of Linen

Linen is also used for cloth, canvases, sails, tents, and paper. Due to its one-time common use to make fine fabric, "linens" became the generic term for sheets and pillowcases, although these are now often made of cotton or synthetic fibers
Due to its strength, in the Middle Ages linen was used for shields and gambesons, but also for underwear and other clothing's.
