Science Museum: Material Analysis- TENCEL
TENCEL® is the brand name for a type of lyocell. The fiber is biodegradable and is made from natural cellulose derived from wood pulp. It is manufactured in an eco-friendly closed loop system using a solvent spinning process. This process is designed to minimize the environmental impact and make economical use of energy and water. Lyocell uses an amine oxide as a non-toxic solvent which is continually recycled during the production process. Production plant emissions into the air from smokestacks and from wastewater are significantly lower in comparison to many other man-made fiber operations. This fiber grew significantly in popularity in the late 1990s.
USES
-Clothing
-Towels
-Upholstery fabric
-Blankets
-Bedding
ADVANTAGES
-Biodegradable and can be landfilled, digested in sewage, incinerated or recycled.
-Suitable for individuals with sensitive skin and irritation free
-High tenacity and extremely durable
-Smooth, supple surface and soft to the touch
-Lightweight
-Holds its shape well
-Creates flattering drapes
-Mostly machine washable
-Quick drying
-Inexpensive to manufacture
-Extremely absorbent (absorbs 50% more moisture than cotton)
-The fibrils it is composed from are hydrophilic and have excellent cooling properties so good for temperature control
-Inhibits bacteria growth and therefore considered a naturally hygienic fiber
-Prevents growth of mold
-Can be manipulated to produce a range of different finishes, e.g. suede-like, rugged denim or silky smooth
-Static free
-Wrinkle-resistant
-Can be blended with other fibers, e.g. wool to alter its qualities
DISADVANTAGES
-Difficult to dye without treatment with a number of different harsh, toxic chemicals which are neither environmentally friendly nor suitable for sensitive skins
-Can shrink about 3% with initial washing
-Expensive to purchase (despite being inexpensive to manufacture)
-An inherent tendency to fibrillate or “pill”
-Direct heat e.g. from a hot iron may scorch the fabric
