Composition and Properties of Acrylic Yarn
Acrylic yarn is a synthetic fiber primarily composed of polyacrylonitrile, a polymer derived from acrylonitrile monomers. This chemical structure places acrylic yarn firmly within the category of plastics, as it is essentially a man-made plastic fiber. The polymer chains are long and contain nitrile groups (-CN), which contribute to the fiber’s durability and resistance to environmental factors.
The manufacturing process involves polymerization of acrylonitrile, followed by extrusion through spinnerets to form fibers. These fibers are then spun into yarns suitable for textile applications. Because acrylic yarn is plastic-based, it exhibits several distinct properties:
- Lightweight and warm, often used as a wool substitute
- Resistant to moths, oils, and chemicals
- Colorfast and retains vibrant hues after washing
- Quick drying and moisture-wicking
- Can pill over time due to fiber abrasion
Its plastic nature also means acrylic yarn has some limitations, such as susceptibility to heat damage, lower breathability compared to natural fibers, and environmental concerns related to microplastic shedding during washing.
