To determine which category Dacron belongs to, we should first understand what each of the options represents:

1. **Polyamide**: These are synthetic polymers that contain repeating amide linkages. Common examples include Nylon.

2. **Polypropylene**: This is a thermoplastic polymer used in a variety of applications. It is made from the polymerization of propylene monomers.

3. **Polyester**: These are polymers that contain the ester functional group in their main chain. Dacron is a type of polyester.

4. **Polyethen**: Also known as polyethylene, this is a common plastic often used in containers and packaging.

Since Dacron is recognized primarily as a polyester fiber, the correct answer is:

### Final Answer
**C. Polyester**
