Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. For a fiber to be called acrylic in the U.S, the polymer must contain at least 85% acrylonitrile monomer.Typical comonomers are vinyl acetate or methyl acrylate.trong and warm, acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn.
Industrial polyester fibers, yarns and ropes are used in tyre reinforcements, fabrics for conveyor belts, safety belts, coated fabrics and plastic reinforcements with high-energy absorption. Polyester fiber is used as cushioning and insulating material in pillows, comforters and upholstery padding.Polyester fabrics are highly stain-resistantâ in fact, the only class of dyes which can be used to alter the color of polyester fabric are what are known is disperse dyes.Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties.olyester fabrics are highly stain-resistantâ in fact, the only class of dyes which can be used to alter the color of polyester fabric are what are known is disperse dyes.
