Each fibre has particular properties which help us to decide which particular fibre should be used to suite a particular requirement. Certain fibre properties increase its value and desirability in its intended end-use but are not necessary properties essential to make a fibre. Thus it is very essential to know the individual aspects and specific properties of each kind of fibre.
Acrylic fibres are polymers formed by addition polymerization of at least 85% by weight of a chemical called acrylonitrile or vinyl chanide. To polymerise vinyl cyanide the double bond between the first two carbon atoms is broken and the molecules attach themselves to each other in a linear chain.
