Color: white Fiber length: depending on use Fiber fineness: 1.5 dtex Strength: 30–35 cN/tex Elasticity: 50–75% It has excellent properties for sports and functional clothing, underwear, bed linen, fillings, nonwoven textiles, and packaging materials. It is highly breathable, quick-drying, with good resistance to stains, UV radiation, and pilling. After use, it can be composted—it does not burden the environment and does not generate microplastics. Ingeo represents one of the most significant advances in sustainable textile materials, combining the properties of natural resources with the performance of synthetic fibers. It is important to clarify that Ingeo is not technically viscose, but a polylactic acid (PLA) fiber made from corn through a fermentation process. This polysynthetic material is produced by NatureWorks LLC and represents the first and only commercially produced fiber made from 100% annually renewable resources such as corn, not petroleum. History and Development of Ingeo Fiber The history of Ingeo dates back to 1989, when it began as a research project by Cargill focused on finding innovative uses of plant sugars as raw material for more sustainable plastics. In 2001, a joint venture was formed between Cargill and Dow Chemical Company under the name Cargill Dow LLC, and in 2005 Cargill acquired Dow’s share. The production facility in Blair, Nebraska began operation in 2002 and is the first and largest PLA facility in the world. Commercial Development Tencel was originally registered as a trademark in 1982, but the real breakthrough came in 1992 when Ingeo Lyocell was introduced to the market and first used in the denim industry. In 2009, NatureWorks LLC established an annual production capacity of 140,000 tons of Ingeo biopolymer. The company is now jointly owned by Thai chemical producer PTT Global Chemical and Cargill. Manufacturing Process Raw Material and Conversion Ingeo fiber production begins with corn processing on a 600-acre site near Omaha in Blair, where corn is separated into four components: sugar, protein, oil, and fiber. NatureWorks uses the sugar, which is fermented into lactic acid and then directly transferred to the facility for production of lactide and polymer. The process involves fermentation of simple plant sugars similar to yogurt production. From 33 pounds of sugar obtained from one bushel of corn, more than 19 pounds of PLA can be produced, including sugar used for biomass growth and biocatalyst organisms for fermentation. The process begins with a liquid lactic acid product, which self-condenses into oligomers of desired length. These are then fed into a lactide reactor, where lactic acid units cyclize and evaporate. Conversion to Fiber The fermentation products are transformed into a high-performance polymer called polylactide, which can then be spun or otherwise processed into Ingeo fiber. NatureWorks’ technology was the first to industrially commercialize sugar-to-bioplastic conversion. The resulting polymer can be injection molded, extruded into films, thermoformed into packaging, or spun into textile fibers. Properties of Ingeo Fiber Mechanical Characteristics Density: 1.25 g/cm³, lower than natural fibers and PET Strength: 2.0–6.0 g/d, higher than natural fibers Elastic recovery: 93% at 5% strain (better than other fibers) Melting point: 130–175°C Glass transition temperature: 55–60°C Comfort Properties PLA fiber shows good moisture management and comfort properties, important for sportswear, underwear, and bedding. It has a lower contact angle than PET, improving water wicking. It wicks moisture without absorbing large amounts of water, making it suitable for performance clothing. Flammability Properties Ingeo fibers without flame retardant treatment are a viable alternative to untreated polyester, cotton, nylon, acrylic, and wool. LOI testing shows slow-burning behavior (24–26%). They produce significantly less smoke than PET or cotton and release less heat during combustion. Applications in the Textile Industry Apparel Industry Ingeo fibers are widely used in fashion due to their combination of natural fiber benefits and synthetic performance. They are especially suitable for sportswear because of moisture-wicking and antibacterial properties. They also provide better physiological comfort compared to PET/cotton blends. Home Textiles Used for bed linen, pillows, blankets, mattress covers, and similar products. They provide insulation, moisture management, and low odor retention. Their natural, non-irritating properties make them suitable for sensitive skin. Technical Applications PLA is used in geotextiles where biodegradability is required. It is also used in automotive filters, ropes, and abrasive materials due to its strength and durability. It has potential in medical textiles such as bandages and protective clothing due to antibacterial properties. Environmental Aspects Sustainability PLA production uses 65% less energy and produces 63% fewer greenhouse gas emissions compared to conventional plastics. Compared to PET, Ingeo produces 59% fewer emissions and uses 47% less non-renewable energy. Biodegradability PLA can enter biological waste streams and can be recycled like most polyesters. Studies show full biodegradation under composting conditions, breaking down significantly within weeks and leaving no harmful residue. Renewable Resources Ingeo is produced from carbon stored in plants through photosynthesis in the form of dextrose. These sugars are converted into biopolymers through fermentation. The use of renewable crops like corn further improves environmental performance.
