Final answer:
Nylon is a synthetic fiber widely used in carpet manufacturing due to its durability and versatility. Polyester, acrylic, and olefin are also used for their respective qualities such as stain resistance, wool-like texture, and moisture resistance. The correct answer is option: 1) Nylon.
Step-by-step explanation:
A synthetic fiber that is commonly used in manufacturing carpet is nylon. Nylon has a variety of uses in textiles, and it's especially prevalent in carpets due to its durability and resistance to stains. The versatility of nylon makes it suitable for many applications, including clothing, ropes, and upholstery. Another advantage of nylon in carpet manufacturing is its ability to be dyed into many different colors, as well as its resilience and ability to recover from indentation caused by furniture and foot traffic.
Polyester, which is often referred to by its polymer name, polyethylene terephthalate (PET), is another synthetic fiber that is widely used in textiles, like apparel and home furnishings, and also sees use in carpets. It is prized for its stain resistance and is a common choice for carpet fibers due to its affordability and soft feel.
Acrylic and olefin (polypropylene) are additional synthetic fibers used in carpet making. Acrylic closely resembles wool and offers a soft, warm feel, making it suitable for area rugs and carpeting. Olefin is highly resistant to moisture, mold, and mildew, and it's often chosen for indoor-outdoor carpets and basements.
