Final answer:
Synthetic fibers are made of long strings called polymers, with types such as nylon, acrylic, and Kevlar used in various applications. The manufacturing processes can be complex and involve high-temperature reactions like pyrolysis. Environmental concerns arise with non-biodegradable fibers contributing to microplastic pollution.
Step-by-step explanation:
Synthetic fibers are made of long strings called polymers, which are composed of repeating units of compounds connected by chemical bonds. Some well-known synthetic fibers include nylon, acrylic, and Kevlar, each with unique properties and uses.
For instance, nylon is known for its strength and is used in products like parachutes and clothing. The production of synthetic fibers like graphite fibers or those made from carbon nanotubes involves multistep processes, often requiring high temperatures to transform precursor materials through reactions like pyrolysis.
Acrylic fibers, such as those trademarked under the name Orlon, are also popular for their warmth and are often used in clothing and furnishings. Microfiber, another type of synthetic fiber, shows versatility in its uses, ranging from apparel to cleaning products, due to its specific characteristics like softness and toughness.
However, sustainability is a concern with some synthetic fibers such as polyester and nylon, as they are not biodegradable and can contribute to microplastic pollution.
