Which of the following is currently used as a tyre cord?

Options

A. Terylene
B. Nylon-6
C. Bakelite
D. Polyethylene

Answer

To determine which polymer is currently used as a tyre cord, we will analyze the options provided and identify the correct answer step by step.

### Step 1: Understand the Options
The options given are:
1. Terylene
2. Nylon-6
3. Paclite
4. Polythene

### Step 2: Analyze Each Polymer
- **Terylene**: Also known as Dacron, it is primarily used in the manufacture of clothing and fabrics. It is not used for tyre cords.

- **Nylon-6**: This polymer is known for its strength and durability, making it suitable for various applications, including tyre cords. It is produced from caprolactam and is specifically used in the manufacturing of tire cords due to its excellent tensile strength and resistance to abrasion.

- **Paclite**: This polymer is used for making switches, raincoats, and other plastic materials. It is not typically used for tyre cords.

- **Polythene**: Commonly used for making plastic bags, containers, and other hard plastic items, it is not suitable for tyre cords due to its lower strength compared to nylon.

### Step 3: Identify the Correct Answer
Based on the analysis, the polymer that is currently used as a tyre cord is **Nylon-6**.

### Conclusion
The correct answer to the question "Which of the following is currently used as a tyre cord?" is **Nylon-6**.
