  1. Lyocell Fibre
  2. Also named Tencel Composition Wood cellulose (eucalyptus trees, oak, and birch trees)and synthetic substances [17] Microscopic appearance smooth and circular cross section Diameter 11-13 m crons Aesthetic lustre and good drapability Stretchability low Shrinkage low Resiliency moderate and hence they wrinkle Absorbency good ; moisture regain is 11.5% Crystallinity High- 0.62; hence high strength Tensile strength high ; strongest cellulosic fibre when dry and (first man made fibre to be ) stronger than cotton in wet state. damage Can be damaged by mildew and silver fish Ecofriendly Biodegradable Fabric breathability high Fibrillation high
  3.  Fibrillation – longitudinal splitting of fibre to give micri fine surface hairs of diameter less than 1.4 micron Fibrillation is due to high crystallinity it weakens the mother fibre and if it is not done in a controlled manned it gives the appearance of piling  Lyocell can take high ironing temps. It will scorch and not melt
  4. History 1855 George patented artificial silk & Swan succeeded in creating cellulose textiles Count Hilaire de Chardonnet, successfully exhibit artificial silk 1889 1891 Chardonnet built a plant to produce his new fabric in Besancon Experimentation with NMMO by D.L. Jonhnson and American Enka 1966 1979 American Enka created regenerated cellulose fibre which wasn’t commercially viable Courtaulds created lyocell and started manufacturing 1982 1988 Mass production of Lyocell 25 tons/week Lyocell fibre holds the value of 513.8M USD globally 2020
  5. Production process of Lyocell
  6. Lets start from the start…….  Lyocell is a manmade fibre derived from cellulose, better known in the United States under the brand name Tencel.  lyocell is produced from hardwood pulp that is broken down mechanically, then dissolved so the cellulose strands may be extracted.  It is primarily found in the garment industry, particularly in women's clothing.
  7. Extraction process • Preparing the wood pulp 1. Harvested by the loggers 2. Logs are feed into chippers 3. Mill workers load the chips into a vat of chemical digesters. 4. It is dried in a huge sheet, and mill workers roll it onto spools. 5. Dissolving the cellulose

  9. Advantages  Recovery technology of the NMMO. The lyocell process allows reduced consumption of chemicals by several times in comparison to the viscose fiber.  Consumer far less energy than synthetic fibres, and consequently are lower carbon emitters Biodegdradable  Properties of lyocell fibers such as high water retention ability, comfort, and enhanced breathability propel its demand Challenges  High cost of production and the lack of availability of advanced technology for manufacturing lyocell fibers are estimated to hamper the lyocell fibers market during the forecast period.  Additionally, lack of awareness about lyocell fiber is projected to adversely affect the market in the near future.  The fairly low surface energy of Lyocell fiber makes it difficult for dyes to bind to it during production.
  10. Producing countries Producing regions  Asia Pacific  North America  Europe  Middle East and Africa  Latin America  Asia Pacific exhibits a clear dominance  Mexico represents a significant market for Lyocell in textiles Producer companies  Lenzing AG , Acegreen Eco-Material Technology Co., Ltd. Aditya Birla Group, Baoding Swan Fiber Co. Ltd., Chonbang Co., Ltd., Weiqiao Textile Company Limited, Zhejiang Yaojiang Industrial Group Limited, China Populus Textile Ltd., Great Duksan Corp., Qingdao Textiles Group Fiber Technology Co., Ltd. , Smartfiber AG, Acelon Chemicals & Fiber Corp.  Lenzing, spread across the globe, is the largest producer and manufacturer of lyocell fibre Cost of Lyocell  It was originally produced as cheaper alternatives to silk, but due to expensive production techniques it is costlier than cotton. Lyocell is generally more durable, with less time for washing and ironing, making the cost difference quite difficult to quantify.

  13. Supply dynamics - 2019  Cultivation of natural fibers decreased 3% to 32 million tons  Man-made cellulosic fibers continued their dynamic growth, expanding more than 6% to 7 million tons.  Synthetics achieved 5% growth thanks to robust expansion of polyester (PET) filaments and staple fibers.  Spunlaid nonwovens, newly included in global supply, slowed to the lowest growth rate in the century at nearly 4% to reach almost 7 million tons.  Source - Chemical Fibers International 2/3 2020, September 2020 The Fiber Year 2020 – Deceleration along the textile chain
  14. Uses of Lyocell  Apparels - denims, knitwear, sportswear, coats In 2016, the apparels segment accounted for more than half of the global lyocell fiber market.  Home textiles - bed sheets, drapes, curtains, and carpets  Surgical products - absorbent pad, wound-contact layer, elastic and non-elastic bandages, compression bandages, gauze dressing and wipes  Baby diapers  Automotive sector - filters, seat covers, battery separators  Cigarette filters  It also finds application in dehumidification sheets and a precursor for carbon fiber.

  16. Comparative study of lyocell with cotton  Comfort – Lyocell is softer than cotton. The softness of lyocell is due to its smooth surface.  Hygiene-Moisture regain of lyocell is 13% and cotton has moisture regain value is 8.5%.  Lustre -Lyocell imparts excellent lustre to fabrics, garments remain true, even after repeated washing. Cotton is non lustrous material. Mercerisation is an industrial process involving sodium hydroxide for cotton yarns or fabrics to increase the lustre and dyeability.  The price -Compared to cotton, Lyocell is more expensive. Example H&M shirts  Wrinkle resistance – cotton has low wrinkle resistant where as the round shape of the Tencel fiber makes it less prone to wrinkling. ₹2500 ₹1500
  17. Current scenario  The Lenzing Group is planning to establish world's largest lyocell plant in Thailand.  Sateri’s investment in lyocell is very much aligned with the aim for technical and product upgrading for China’s textile industry.  Lenzing group opened first supply chain solution hub in Mumbai. For Lenzing India serves as a key market for export and domestic use.  Lenzing associated with designers like Anita Dongre, Rajesh Pratap Singh, and brands like Global Desi, Ddecor, Levis.
  18.  In terms of consumption, Asia Pacific dominated the global lyocell market in 2018. Favorable growth of the textile industry in emerging economies such as China and India has created a highly conductive environment for growth of lyocell fabrics market in the region. According to India Brand Equity Foundation, the Indian textile industry is projected to reach US$ 230 Billion by the end of 2020  Top consumers of lyocell fabrics in the global market include Inditex Clothing Company, Hennes & Mauritz AB, G-Star Raw, Lindex Fashion Company, Eileen Fisher, Williams-Sonoma Inc., Patagonia, Inc., Continental Clothing, Fjällräven and C&A.
  19. Future  “Lyocell Fabric Market" is valued at 513.8 million USD in 2020 is expected to reach 750.6 million USD by the end of 2026  Textiles is an industry that contributes close to 10% to global carbon emissions. Using more lyocell means less water is expended, compared with cotton. By any measure, lyocell is a part of the solution for a greener and more sustainable fashion sector which is needed immediately.  With global share holding of only 6.4% and 68.3 by synthetic fibers, a lot of push is required to its demand so as to replace the synthetic fibres for a better future.
