Which type of fiber is categorized as a polyester fiber?

Ethibond is categorized as a polyester fiber due to its chemical composition and the way it is manufactured. Polyester fibers are synthetic fibers made from polymeric substances, and Ethibond is specifically a type of polyester that is commonly used in surgical sutures. Its structure allows it to maintain strength, flexibility, and resistance to degradation, which are essential properties in medical applications.

In contrast, Aramid is known for its strength and heat resistance, primarily used in applications like Kevlar. Nylon, while also a synthetic fiber, is known for its elasticity and is primarily classified as a polyamide. Cotton is a natural fiber with different properties and does not fall into the polyester category.
