Properties/Characteristics of Linen Fiber
Linen Fiber:
Linen is a cellulosic fibers derived from the stem of the flax plant
or a fabric made from these fibers. Linen fibers are much stronger and
more lustrous that cotton; they yield cool, absorbent fabrics that
wrinkle easily. Fabrics with linen-like texture and coolness but with
good wrinkle resistance can be produced from manufactured fibers and
blends.
Properties/Characteristics of Linen Fiber:
Linen is comfortable, good strength, twice as strong as cotton, hand-washable or dry-cleanable, crisp hand tailors, well absorbent dyes and prints, well light weight to heavy weight, no static or pilling problems, fair abrasion resistant etc. Basically there are two types of properties of linen fibers. One is physical properties and another is chemical properties.

Linen is comfortable, good strength, twice as strong as cotton, hand-washable or dry-cleanable, crisp hand tailors, well absorbent dyes and prints, well light weight to heavy weight, no static or pilling problems, fair abrasion resistant etc. Basically there are two types of properties of linen fibers. One is physical properties and another is chemical properties.
Physical Properties of Linen:
Physical properties of linen fibers are given below:
- Tensile Strength: Linen is a strong fiber. It has a tenacity of 5.5 to 6.5 gm/den. The strength is greater than cotton fiber.
- Elongation at break: Linen does not stress easily. It has an elongation at break of 2.7 to 3.5 %.
- Color: The color of linen fiber is yellowish to grey.
- Length: 18 to 30 inch in length.
- Lusture: It is brighter than cotton fiber and it is slightly silky.
- Elastic Recovery: Linen fiber has not enough elastic recovery properties like cotton fiber.
- Specific Gravity: Specific gravity of linen fiber is 1.50.
- Moisture Regain (MR %): Standard moisture regain is 10 to 12%.
- Resiliency: Very poor.
- Effect of Heat: Linen has an excellent resistance to degradation by heat. It is less affected than cotton fiber by the heat.
- Effect of Sun Light: Linen fiber is not affected by the sun light as others fiber. It has enough ability to protect sun light.
Chemical Properties of Linen:
Linen is a natural cellulosic fiber and it has some chemical properties. Chemical properties of the linen fiber are given below:
- Effect of Acids: Linen fiber is damaged by highly densified acids but low dense acids does not affect if it is wash instantly after application of acids.
- Effects of Alkalis: Linen has an excellent resistance to alkalis. It does not affected by the strong alkalis.
- Effects of Bleaching Agents: Cool chlorine and hypo-chlorine bleaching agent does not affect the linen fiber properties.
- Effect of Organic Solvent: Linen fiber has high resistance to normal cleaning solvents.
- Effect of Micro Organism: Linen fiber is attacked by fungi and bacteria. Mildews will feed on linen fabric, rotting and weakling the materials. Mildews and bacteria will flourish on linen under hot and humid condition. They can be protected by impregnation with certain types of chemicals. Copper Nepthenate is one of the chemical.
- Effects of Insects: Linen fiber does not attacked by moth-grubs or beetles.
- Dyes: It is not suitable to dye. But it can be dye by direct and vat dyes.
Major End Uses Linen Fabric:
