  1. SYNTHETIC FIBRES :ACRYLON RAKSHIT-YASHASVI-KAVYA-SHIVAM

  2. Acrylic fibers are synthetic fibers made from a polymer with an average molecular weight of ~100,000, about 1900 monomer units. 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. DuPont created the first acrylic fibers in 1941 and trademarked them under the nameOrlon. Acrylic is also called acrilan fabric. As it resembles silk, it is also called artificial silk. It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. Strong 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. • Modacrylic is a modified acrylic fiber that contains at least 35% and at most 85% acrylonitrile monomer. The comonomers vinyl chloride, vinylidene chloride or vinyl bromide used in modacrylic give the fiber flame retardant properties. End-uses of modacrylic include faux fur, wigs, hair extensions and protective clothing. Yashasvi

  4. They have long lasting luster. • They are light weighted and have more bulk. • They do not shrink on washing. • They dry quickly. • They are easy to clean. • They do not wrinkle . • They need very little or no ironing Kavya

  5. They are comfortable to wear due to high moisture management. • They have good elasticity. • They last longer as compared to natural fibers. Kavya

  6. These are used for making blankets ,which are very light and have the same warmth as woollen blankets. Articles made from acrylic are cheap and are available in variety of colours. Acrylic takes color well,Is washable and is generally hyboallergenic.

  7. On the other hand, it can be useful in certain items like garments for babies which require constant washing ,because it is machine-washable &extremely color fast. Its fibres are very resilient compared to both other synthetics and natural fibres.

  8. Acrylic is a fiber manufactured with a combination of toxic substances. • Acrylic is not as strong as other synthetics, has poor resistance to matting, and is stained by oil and grease. • Acrylic’s manufacturing process if not properly monitored can result in an explosion. Acrylic fibers are highly inflammable and non biodegradable in the environment.

  9. They also pill. • Some times people may also get skin allergies on wearing clothes made of acrylic fibre. • Since acrylics are man made fibers, they do not breath like cotton or other natural fibers so people will feel hotter in them when they sweat.
