Material composition of viscose
Viscose is a popular textile material made from natural and synthetic components. To understand what viscose is really made of, it's important to look at its main components and the chemical process by which it is produced.
Cellulose as a base
The main component of viscose is cellulose, which is derived from plant materials, particularly wood. Cellulose is a natural polysaccharide that forms the structure of plants. It is one of the most abundant organic compounds and is valued in the textile industry for its excellent properties. Using cellulose as a base offers several advantages:
| Advantage of cellulose in viscose |
|---|
| Biodegradable |
| High breathability |
| Good dye uptake |
| Comfortable to wear |
Chemical treatments during the manufacturing process
The production of viscose involves several chemical treatments to break down the cellulose and transform it into a malleable fiber. The process begins with soaking wood in an alkaline solution, which separates the cellulose from other components. This is followed by treatment with carbonizing chemicals to extract the viscose fiber. The process can be broken down into the following steps:
| Step | Description |
|---|---|
| 1. Pulp production | The wood is shredded and treated with caustic soda. |
| 2. Dissolve | Cellulose is transformed into a thick, viscous solution. |
| 3. Spiders | This solution is forced through spinnerets to form fibers. |
| 4. Networking | The fibers are treated with chemicals to increase their stability. |
Chemical treatments are crucial to achieving the desired properties of viscose, such as its softness and adaptability.
