Which of the following is NOT associated with polyester fibers?

Polyester fibers are extensively recognized for their unique characteristics, and understanding these attributes helps clarify why flammability is not typically associated with polyester.

Polyester is inherently resistant to wrinkling and shrinking, contributing to its durability in various applications. It also possesses a degree of elasticity, enabling garments made from polyester to retain their shape without stretching or sagging over time. In addition, polyester is known for its water-resistant properties, making it a popular choice in fabrics that need to repel moisture or dry quickly.

Flammability is a concern for several materials, but polyester has a higher ignition temperature compared to natural fibers like cotton or wool. While it can melt under extreme heat, polyester is not categorized as highly flammable. Thus, the attributes of elasticity, durability, and water resistance are all associated with polyester, while flammability does not represent a typical characteristic of this fiber.
