![Introduction
• Lyocell is a form of rayon.
• It consists of cellulose fibre, 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](https://image.slidesharecdn.com/southeast-200930105221/85/Regenerated-fibre-lyocell-3-320.jpg)

- 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 ofLyocell 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 lyocellFiber • 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 betweenLyocell 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 LyocellFiber 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.
