Polyester and polyester fiber are two very common synthetic fibers. They are similar in many ways, but there are also some differences. We can't simply judge which fabric is better, because it depends on personal needs and preferences. The following are some comparisons between these two fibers:

1. Performance characteristics:

Polyester has high strength and elasticity, wear resistance, wrinkle resistance, corrosion resistance, easy washing and quick drying, and is widely used.

Polyester fiber also has high strength and elasticity, good wrinkle resistance and shape retention, but poor hygroscopicity. Polyester fiber fabrics are widely used in making clothes, bedding and so on.

2. Comfort:

Polyester fiber is soft and has poor hygroscopicity, so it may feel uncomfortable in a humid environment.

Polyester is hard and has poor air permeability, but it is wear-resistant and wrinkle-resistant and easy to handle.

3. Durability:

Both polyester and polyester fiber have good durability, but the specific durability will be different due to factors such as usage and maintenance habits.
