Regenerated fiber lyocell. Lyocell is a form of rayon.
It consists of cellulose fiber, made from dissolving pulp and then reconstituting it by dry jet-wet spinning.
The fibre is used to make textiles for clothing and other purposes
Lyocell [Lyo from Greek lyein=dissolve & Cell= from cellulose]
The lyocell process was developed in 1972 by a team at the now-defunct American Enka fibers

5. Lyocell Fiber Properties
1. Soft, Strong, absorbent.
2. Fibrillated during wet process to
produce Special texture.
3. It has highly wet and dry strength,it
is stronger then cotton and wool.
4. wrinkle resistance.
5. very versatile,dyeable to vibrant
colours,with a variety of effects
and textures.
6. can be hand washable
7. Simulates silk,suede,or leather
touch.
8. Good drapability.
9. Biodegradable.
10. Fine yarn counts can be spun.
6. Environmental Impact of Lyocell
1. Fibrer Source
Natural,lyocell is a
material made from
wood pulp.
2. Lyocell is
biodegradable
3. Destruction Low-
lyocell is
manufactured by an
environmentally-
friendly.
7. Uses of lyocell Fiber
• Professional Business Wear
• Leotards
• Hosiery
• Casual Wear
• Upholstery
• Window Treatment fabrics
• Filters
• printer's blankets
• specialty papers
• Medical dressings
• Botanic tecel bed
8. Main differences between Lyocell
and cotton
1. Comfort
2. Hygiene
3. Freshness
4. Durability
5. The price
6. Aesthetics
9. Lyocell Merits & Demerits
Merits
• Durability
• Anti-bacterial
• Fabric texture
• Moisture Absorbent
• Appropriate for
sensitive skin
• Flexible
Demerits
1. Price
From a consumer’s perspective,
lyocell fabric is more expensive. This
is because of the technology used in
processing.
2. Fairly low surface energy
The fairly low surface energy of Lyocell
fiber makes it difficult for dyes to
bind to it during production.
10. Summary Of Lyocell Fiber
1. Lyocell is 100% cellulose and such it is biodegradable.
2. The fibre has also the potential for re-used and
remanufacture
3. Thes low fibrillation fibers are also considered to be
more resistant to biodegradation.
4.Composting, incineration and landfill can all be used as
end of life options.
