Question

differentiate between synthetic and semi synthetic fibres

Answer 1

Answer:

Semi-Synthetic Fibers

Semi-Synthetic FibersSemi-synthetic fibres are made from natural raw materials with a naturally occurring long-chain polymer structure and are only modified and partially degraded by chemical processes. Most semi-synthetic fibres are cellulose regenerated fibres, the earliest of which is rayon, also known as viscose.

Answer 2

Answer:

Synthetic polymers

• Synthetic polymers are human-made polymers derived from petroleum oil.
• From the utility point of view they can be classified into three main categories: thermoplastics, elastomers and synthetic fibers.
• They are found commonly in a variety of consumer products such as honey, glue, etc.

Semi synthetic

• Semisynthetic is a type of chemical synthesis that uses chemical compounds isolated from natural sources as the starting materials to produce other novel compounds with distinct chemical and medicinal properties.
• The novel compounds generally have a high molecular weight or a complex molecular structure, more so than those produced by total synthesis from simple starting materials.
• Semisynthesis is a means of preparing many medicines more cheaply than by total synthesis since fewer chemical steps are necessary.
