Which of the following is an example for fibre?
Show Hint
The Correct Option is D
Solution and Explanation
Step 1: Understanding Fibre Polymers
Fibres are polymers that exhibit high tensile strength and elasticity, making them suitable for textile and industrial applications.
Step 2: Analyzing the Given Options
1. Polyvinyl chloride (PVC) - \(\left[ \text{CH}_2 - \text{CH} - \text{Cl} \right]_n\)
This is a thermoplastic polymer, not a fibre. 2. Polyethylene (PE) - \(\left[ \text{CH}_2 - \text{CH}_2 \right]_n\)
This is a simple plastic material, not a fibre. 3. Polyvinylidene chloride (PVDC) - \(\left[ \text{CH}_2 - \text{C} - \text{CH} - \text{CH}_2 \right]_n\) (Cl attached to C)
This is used for packaging materials but not a fibre. 4. Polyethylene terephthalate (PET) - \(\left[ \text{OC} - \text{CO} - \text{O} - \text{CH}_2 \text{CH}_2 \text{O} - \text{CO} - \text{O} \right]_n\)
This is a fibre polymer known as polyester, commonly used in fabrics.
Step 3: Conclusion
Since PET is widely used as a fibre material, the correct answer is: \[ \boxed{\left[ \text{OC} - \text{CO} - \text{O} - \text{CH}_2 \text{CH}_2 \text{O} - \text{CO} - \text{O} \right]_n} \]
Top Questions on Polymers
- A polymer melt being extruded through a spinneret hole of circular cross-section exhibits a die-swell ratio of 2.2. The extrusion velocity and volumetric flow rate during this extrusion process are 20 m/min and \(2.6 \times 10^{-8}\) m\(^3\)/s, respectively. The maximum diameter (mm) of the extruded melt after exit from the spinneret hole (rounded off to 2 decimal places) is:
