What is acetate cellulose?

Cellulose acetate is a substance produced by a person that is derived from naturally occurring organic compounds - cellulose. Cellulose is the main structural component of plants and is usually considered to be the most common organic compound on Earth. Cellulose acetate is made of wooden pulp by process of cleaning. It is a renewable and biodegradable substance that provides a cheap source of high -quality fiber that can be used in many production processes. These include magnetic computer tape, absorbent surgical bandages and some types of adhesives. Cellulose acetate is also used in photography. Cellulose acetate fiber is sometimes confused with cellulose triacetate, a similar compound that contains a higher proportion of cellulose. Propionate of cellulose acetate is another similar substance that is used for manufacturing a number of plastic objects such as spectacle frames, blister packages and plastic handles such as those that are on cutlery or tools.

Commercial production of this compound is usually done by processing cellulose in the form of wooden pulp through various chemicals. The main one is acetic acid. Accetic anhydride is also usually used in treatment with sulfuric acid. This process is called acetylation, and at the molecular level, cellulose molecules are replaced by acetyl groups, a molecular carbon -based group. After acetylation, the substance can be dissolved and then spinned into its fibrous form to form a product of the textile terminal product.

The

process of acetylation was discovered long ago as 1865 by a chemist named Paul Schützenberger, who worked in France. However, it was not patented as an industrial process until 1894, Charles Crossa Edward Bevan in the UK. Since the 1920s, acetate cellulose has been in commercial production.

When used for clothing, this fiber is soft and durable, well covered and allows the skin to"breathe". Other advantages of this kind of fiber include its resistance to washing in washing, its hypoallergenic properties and its resistance to mold and some forms. In modern production lines, these fibers are often mixed with other substances such as cotton, silk, nylon or wool. The demand for cellulose acetate fiber has decreased in recent years due to the discovery of various polyester fibers.
