Question
Chapter 8, Problem 8.74PAE
Interpretation Introduction
Interpretation:
Synthetic fibers are completely man made fibers which are made by naturally occurring materials by means of chemical process.
Concept Introduction:
There are so many types of synthetic fibers available in daily use. The major types of synthetic fibers are as follows.
1. Polyesters
2. PVC
3. Acrylic
4. Teflon
5. Kevlar
6. Rayon
This can be classified based on their formation mechanism as either addition or condensation based on their mechanism. If the

examples.
During our lectures on polymeric materials, I used polyethylene as an example because of its very straightforward structure.
