The materials mainly used for the production of seat belt webbings are polyester and nylon. Nylon was mainly used in the early years of seat belt production. However, due to Nylon's higher UV degradation resistance, polyester is preferable and most often used for new vehicles all over the world. Polyester is also considered superior to nylon because of its higher stiffness and lower extensibility.
Multiple research tests have been done to decide whether nylon or polyester is better suited for seat belt webbing. Repeatedly polyester was established as the superior fiber with its higher stiffness and lower extensibility. Currently, polyester commands the greater part of the seat belt making market (almost 100%) while nylon commands a small percentage which is mainly for older vehicles.
Nylon stretches more than polyester and as a result it is liable to quicker wear and tear. Nylon seat belt webbing also absorbs water quicker and will grow mildew if not dried very well. Polyester seat belt webbing is stronger overall, has high abrasion resistance and high water resistance which makes it easier and safer to clean.
