Introduction to Polymer and Macromolecule(VIVA question for textile)
Introduction to Polymer and Macromolecule (VIVA question and Details) Mer – The repeating unit in a polymer chain Monomer – A single mer unit (n=1) Polymer – Many mer-units along a chain (n=103 or more) Degree of Polymerization – The average number of mer-units in a chain. POLYMER : Polymer is a type of macromolecule consist by covalent bond of a large number of repeating number. Polymer means many monomer. Monomer: A monomer is a molecule that is able to bond in long chains. Degree Of Polymerization: It is a average number of repeating number in a macromolecule. The importance of polymer science to study for Textile Engineering . 1.Textile fibers are polymeric substance. 2.Size materials are polymer(used in weaving). 3.Printing thickeners are polymer. 4.Binders and fixed used in coloration with pigments are also polymer. 5.Polymers are also used as wet processing. Macromolecule: A macromolecule is a very large molecule with a diame
