Question

what is PET fiber explain​

Answer 1

Answer:

: a synthetic fiber consisting wholly or chiefly of a polyester especially: a quick-drying resilient fiber made in filament and staple form from ethylene glycol and terephthalic acid or its dimethyl ester and often blended with other fibers (as of  wool or cotton)

types and properties of fibres and yarns used in weaving

Polyester fibre, specifically polyethylene terephthalate (PET), is the most important synthetic fibre worldwide in terms of production volume1 due to its low cost, the ease with which it can be processed, and excellent performance.

Answer 2

Polymers are macromolecules that are made up of a series of identical repeating units. Monomers are the units that repeat themselves.

Explanation:

• A polyethylene terephthalate is a terephthalic acid and ethylene glycol condensation polymer.
• Water is a by-product of the reaction that produces this molecule, hence it is an example of step-growth polymerization or condensation.
• There are two types of polymerization based on this mechanism.
• Step-growth and chain-growth polymerization are the two types.
• The monomer units are joined to each other by their numerous bonds in chain growth polymerization, also known as addition polymerization. Polymerization of ethylene, for example, results in the creation of polyethylene polymer, also known as polythene.
