3. What are synthetic fibres? How are they
obtained? What are the differences between
synthetic and natural fibers
Answers
Answer:
Synthetic Fibers
Fibres are fine filaments that either occurs naturally or can be synthesized. Synthetic fibres are man-made fibres produced from chemical substances and are used for making clothes and other useful things. These are made by the process of polymerization. Synthetic fibres can either be completely synthetic or semisynthetic. Fibres that are purely synthetic like nylons, polyesters, acrylics are made from chemicals whereas semisynthetic fibres such as rayons are produced with the utilization of natural polymers as raw material.
Properties of natural fibers are also dependent on the moisture content in the fiber. The presence of water plays a crucial role in the mechanical behavior of natural fibers. Hydrated, biopolymers generally have enhanced ductility and toughness.
