Acrylic, also known as orlon or acrylonitrile, is a very popular synthetic fiber. It was invented in 1941 in the laboratories of the DuPont company. This American company is a chemical tycoon that has many unusual innovations. In 1938, DuPont introduced polyamide, or nylon, to mass production.
Acrylonitrile, i.e. acrylic nitrile, vinyl cyanide, CH2 = CHCN, is a colorless, toxic liquid, with boiling point at 78°C. Mixes with water and organic solvents. Acrylonitrile is obtained by synthesis from hydrocyanic acid and acetylene or from hydrogen cyanide and ethylene oxide. It’s become one of the most important raw materials in the plastics and synthetic fibers industry. It is used in the technology of production of synthetic fibers, synthetic rubbers, nitrile acid. When the fibers contain at least 85% by mass of acrylonitrile they are called polyacrylonitrile, when the acrylonitrile content is lower, it is referred to as copolyacrylonitrile or modacrylic fibers. Depending on the composition, they have different properties, in general acrylic fibers are less resistant to stretching, bending and twisting than polyamide and polyester fibers, they are not resistant to abrasion, while they show excellent resistance to light, they do not get affected by many organic solvents (eg. chloroform), insects and microorganisms do not attack them; acrylic fibers are easily colored, have a soft grip, are wool-like, poorly absorb moisture; they are used mainly in the form of staple fibers, for the production of knitted and clothing fabrics, curtains, artificial fur, blankets.
The advantages of acrylic:
does not get creased easily
not liked by moths, fungi or bacteria
resistant to sunlight
Disadvantages of acrylic:
extremely irresistant to abrasion
The awning fabric from Sako Expo has such properties. We invite you to familiarize yourself with the product.
Acrylic, except that it is not healthy for us, it also does not serve the environment. Its production uses a huge amount of energy and water, and chemicals used in the whole process can significantly pollute the environment. The comfort of wearing things from acrylic is not high due to the fact that it does not absorb moisture (causing faster sweating) and is not airy. In the case of acrylic, hygroscopicity is only 1-2%, while for natural wool – approx. 15%. In addition, it insulates the body to a much lesser degree against low temperatures and wind. Although it may look very thick visually, it is actually not as warm.
