What is Lyocell?

Home» Lyocell vs. Cotton Sheets — Differences and Benefits Choosing bed sheets is a choice far more complex than simply which feels nicer. One must consider how sheets wash, what their cooling potential is, how they look, their price, their durability, and even more specific factors.

Fabrics derived from cellulose date back to the middle of the nineteenth century, though no one commercially produced one until So what is the difference between Rayon and Lyocell? The production process also takes a lot of energy, and the substances used to treat the fibers are derived from petrochemicals.

Lyocell has numerous advantages over rayon and modal in its properties as well as its manufacturing process. One of the major “claims to fame” of lyocell is its ability to absorb excess liquid (perspiration) – at a rate of fifty percent more than cotton – and quickly release it into the atmosphere.

It is primarily found in the garment industry, particularly in women's clothing. Fabrics derived from cellulose date back to the middle of the nineteenth century, though no one commercially produced one until A Swiss chemist, George Audemars, was granted an English patent in for an artificial silk he derived from mulberry bark. Audemars attempted to reproduce the method the silkworm uses for making silk by dissolving the fibrous inner bark of mulberry trees to separate out the cellulose.

To form threads, he dipped needles into the cellulose solution and drew them out. Another chemist, Englishman Joseph W. Swan, modified Audemars' technique by forcing the cellulose solution through fine holes. His main interest was in producing filaments for electric lamps, but Swan realized that it was possible to manufacture a cellulose textile using his extrusion method.

He exhibited cellulose fabric in London in , but he failed to kindle any interest, and the project died out. Commercial production of a cellulosic fiber was first carried out by the French chemist Count Hilaire de Chardonnet.

He exhibited his so-called artificial silk in Paris in , and contrary to Swan's experience, people were thrilled by his new fabric. Chardonnet built a plant in Besancon, France in , and had great success bringing his new fabric, now named rayon, to the forefront of the fashion industry.

In the United States, rayon production began in under the auspices of the American Viscose Company. This company was an affiliate of Samuel Courtaulds and Co. Chemists and manufacturers were intensely interested in manmade fibers in the twentieth century.

Acetate, another cellulosic fiber, was first commercially produced in the United States in Chemists at the Du Pont company developed nylon in the s, and it came into wide commercial use beginning in Acrylic and polyester were two other significant man-made fibers.

These debuted in the s. Nylon, acrylic and polyester differ from cellulosic fibers because they are derived from chemicals, and thus are totally manmade. Lyocell, rayon and acetate are based on the cellulose in wood pulp, and so these are often designated "natural" fibers, though the fibers would not occur except for a manmade process. The manufacturing and processing of artificial fibers underwent much refinement throughout the twentieth century. The first rayon produced by Count Chardonnet, for example, proved to be highly flammable, and the rayon on the market today is quite different.

In the late s and early s, researchers, principally at the leading rayon A diagram depicting the manufacturing processes used to make lyocell fiber.

In this method, the cellulose is softened and then spun into fiber. Conventional rayon, by contrast, is called a "regenerated cellulose fiber," and it involves many more steps.

The cellulose is first chemically converted into xanthate, then dissolved in caustic soda, then regenerated into cellulose as it is spun.

The solvent spinning technique is both simpler and more environmentally sound, since it uses a non-toxic solvent chemical that is recycled in the manufacturing process. The solvent-spun cellulosic fiber lyocell was first produced commercially in the United States in by Courtaulds.

The company used the brand name Tencel. The fabric was given the generic name lyocell in the United States in By this time, there was one other major lyocell producer in the world, the Austrian company Lenzing AG, which had acquired patents and research on lyocell from American Enka when it bought that company's rayon operation in There are some potential disadvantages to Lyocell.

Cotton is often still thought of as the gold standard of bedsheets, and with good reason. However, cotton is not without its issues. Lyocell is a more specialized fabric. Often, the right choice in terms of cotton and Lyocell really just comes down to personal preference in terms of feel, look, durability, ease of care, and price. You should always take into consideration your budget, carbon footprint, body temperature and climate, washing preferences and, most important of all, how you personally like your bedsheets to feel.

For a more extensive overview of all types of sheets, please refer to our Best Sheets page. Benefits Of Cotton Cotton is an extremely popular bed sheet material.

Cotton is well known to last a long time — in fact, some think it actually gets better with age. Cotton fresh from the packet tends to have a very crisp feel; while after a few washes it becomes softer and less rigid. White cotton sheets are likely to look newer for longer too, thanks to this possibility of bleaching. Cotton can be washed at high temperatures and dried with little to no risk of shrinking or thinning. It comes in a wider range of price brackets, so you can potentially get better quality for your money.

Drawbacks Of Cotton In spite of its popularity, cotton is not without its flaws. A brand new set of cotton bedsheets can feel quite rough, stiff and starchy.

However, over time cotton tends to soften up. There is a huge variety in quality of cotton bedsheets. A high end, Egyptian cotton set of sheets may have little in common with a bargainous cotton-poly blend. Cotton sheets, particularly fresh out of the drier, are notoriously prone to creasing. The best way to mitigate this is through ironing or by allowing the sheets to hang to dry naturally. Benefits Of Lyocell Lyocell is a more specialized, innovative fabric.

Lyocell fibers are hydrophilic, which means water-loving. In terms of bedsheets, this means they move water particles away from the body. Lyocell sheets likely need less frequent washing than cotton. These hydrophilic fibers also mean far less sweat will collect between the body and the bedsheets, making Lyocell an ideal choice for hot sleepers or those in more humid countries. Lyocell sheets last a long time before needing to be replaced.

They wash well without become flimsy, thin or misshapen over time.

Lyocell is a natural, man made fibre. Made with wood pulp from sustainable tree farms, lyocell textiles are created through the use of nanotechno Lyocell Fabric What is Lyocell FabricLyocell fabric is an amazing eco friendly fabric that represents a milestone in the development of environmentally sustainable textiles. Lyocell is a manmade fiber derived from cellulose, better known in the United States under the brand name Tencel.
