Fibres are linear chain polymers in which the individual chains are held together by hydrogen bonding or dipole-dipole attraction. The polymeric chain is highly ordered with respect to each other.
In case of nylon (polyamides), the intermolecular forces are due to H− bonding, while in polyesters (terylene or dacron) and polyacronitrile (orlon, acrylin), dipole -dipole interactions between the polar carbonyl (C = O) groups and between carbonyl and cyano (-C ≡ N) groups, respectively.

Which of the following pair of polymers is fiber?a)Polythene, PMMAb)P...
Polyester and PAN (polyacrylonitrile) are both examples of fiber polymers.
Polyester:
- Polyester is a type of synthetic polymer that is commonly used in the production of textiles and fibers.
- It is made by condensing a dicarboxylic acid with a diol, resulting in a polyester chain.
- Polyester fibers are known for their strength, durability, and resistance to stretching and shrinking.
- They are commonly used in clothing, upholstery, and other fabrics.
PAN (Polyacrylonitrile):
- PAN is a type of synthetic polymer that is widely used in the production of fibers.
- It is made by polymerizing acrylonitrile monomers to form a PAN polymer chain.
- PAN fibers are known for their high strength, resilience, and flame resistance.
- They are commonly used in applications such as carbon fiber production, protective clothing, and filtration systems.
Comparison with other options:
- Polythene (polyethylene) is a type of polymer that is commonly used in the production of plastic bags and containers. It is not typically used in fiber production.
- PMMA (polymethyl methacrylate) is a transparent thermoplastic that is often used as a substitute for glass. It is not commonly used in fiber production.
- Urea-formaldehyde is a type of thermosetting polymer that is used in the production of adhesives and molded products. It is not used in fiber production.
In conclusion, the pair of polymers that includes polyester and PAN is the correct answer as both of these polymers are commonly used in the production of fibers.
