Substances and their properties

Cotton is a natural plant fiber and consists of about 91 percent cellulose, which is extracted from the fruit capsules of the cotton plant.

Viscose is one of the man-made fibers with a natural base material, cellulose. Thus, viscose, i.e. viscose fibers, is not a man-made fiber. The raw material is mainly obtained from wood. Viscose is also known as "rayon" or artificial silk and is often used as a cheaper alternative to silk made from staple fibers.

Linen fiber is a natural plant fiber made from the stems of the flax plant and is an absolute summer fabric. It is used for clothing as well as for bedding and quilts. The basic building block of the fiber is 70 percent cellulose, and it also contains vegetable glues and waxes.

Silk is a natural animal fiber and refers to those fibers that are obtained exclusively from the cocoons of the silk-spinning caterpillars, the silk moth. One can use only the silk threads of the mulberry moth, a particular species of butterfly.

Wool is a natural animal fiber and refers to the undercoat of sheep, as well as some camel, goat and rabbit species. Pure new wool is obtained during wool shearing from live animals, which was processed for the first time. This type of wool is of the highest quality. The thickness and properties of wool fibers depend on the particular breed of sheep. Wool is a fine, soft, shiny and slightly elastic fiber. It wrinkles little, is heat insulating and temperature balancing. It is also dirt and moisture repellent and has good absorbency.

Polyester is a man-made fiber and microfiber and consists of polyethylene terephthalate, or PET for short. The basic building materials are hard coal, lime, crude oil and natural gas. Polyester is also used in other applications such as plastic bottles, known as PET bottles. Polyester fibers are popular in many areas because they have the highest tear and abrasion resistance.
