Unlike synthetic manufactured fibers, **cellulosic manufactured fibers**, also known as **regenerated cellulose fibers**, are made from plants. They are not, however, like natural cellulosic fibers such as cotton or flax. As the name suggests, cellulosic //manufactured// fibers are synthetic fibers that are plant based. In the manufacturing process the plants are broken down into chemical solutions which are then forced through (or extruded through) tiny holes to make filaments that will be made into threads and yarns later. Wood is primarily used to make these fibers, but in the last few years the manufactured fiber industry has been developing other cellulosic manufactured fibers made from things like corn, soy proteins, milk proteins and bamboo.

Cellulosic manufactured fibers are used mostly in the apparel industry, but some of them are used in industrial settings as well. Unfortunately, their properties are not very good, and so they are mixed with other fibers usually to help fix the bad properties. Cellulosic manufactured fibers have a low strength usually, especially when they are wet. They have a low abrasion resistance, which is resistance to rubbing and contact with the fabric. Most of them are sensitive to sunlight. If the fabric is put into the sunlight and left in the sunlight for long, then they will suffer from a loss in strength. Most of the cellulosic manufactured fibers have a low resistance to insects, especially silverfish, as well as mold and mildew.

There have been many attempts to create cellulosic manufactured fibers throughout the years. The idea was to imitate how the silkworm creates its silk. The year was 1832, and the first cellulosic manufactured fiber was created. It was the first **rayon** fiber to ever be created. They called it nitrocellulose, and it was often known as artificial silk. Of course after this, there were a number of other experiments and developent, resulting in a lot of commercial fibers that were produced during the twentieth century. A lot of those commercial fibers are the ones used today

There are a number of cellulosic manufactured fibers. Some examples include:
 * __rayon__- regenerated cellulose fiber
 * __bamboo based fibers__
 * __acetate and triacetat__- derivative cellulose fibers
 * __SoySilk__- made from soy proteins.
 * __Tencel__- brand name of a material made from lyocell; regenerated cellulose fiber

On this wiki page, we'll be focusing only on three types :
 * Rayon
 * Acrylic
 * Tencel.
