Which of these synthetic fabric types consist of Dacron and Terylene?

Options

A. Acrylic
B. Nylon
C. Polyester
D. Rayon

Explanation

To answer the question regarding which synthetic fabric types consist of Dacron and Terylene, we can follow these steps:

### Step 1: Identify Dacron and Terylene
Dacron and Terylene are both synthetic fibers that are made from the same type of polymer. They are essentially different names for the same material, which is a type of polyester.

### Step 2: Understand the Composition
Both Dacron and Terylene are produced from the polymerization of two main components: ethylene glycol and terephthalic acid.

### Step 3: Describe the Polymerization Process
The polymerization process involves a condensation reaction where ethylene glycol (HO-CH2-CH2-OH) reacts with terephthalic acid (C6H4(COOH)2). During this reaction, water molecules are released, leading to the formation of long chains of polyester.

### Step 4: Identify the Type of Polymer
The resulting polymer from this reaction is a polyester, characterized by the ester linkages formed between the ethylene glycol and terephthalic acid.

### Step 5: Conclusion
Thus, the synthetic fabric types that consist of Dacron and Terylene are both classified as polyester fabrics.

### Final Answer
Dacron and Terylene are both types of polyester fabrics.
