Acrylic fibres are less flammable than cotton but more flammable than polyester and wool. The high content of carbon (67.9%) makes acrylic fibres highly preferable for the use as precursor for the production of carbon fibres with the yield of 50–55% ( Morgan, 2005 ). Acrylic fibres can be dyed with cationic dyes, anionic dyes or disperse dyes.
