Physical Properties of Polymers
Physical Properties of Polymers Polymer: A chemical compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units is called ‘Polymer’. Polymers range from familiar synthetic plastic such as polystyrene to natural bio-polymers such as DNA and proteins that are fundamental to biological structure and function. Physical Properties: Physical properties of polymers […]
Auxilaries Of Disperse Dye
Part 1 : Disperse Dye for Polyester | Why called disperse dye | Application and mechanism Part 2 : Method of polyester dyeing | Polyester Dyeing process Auxilaries Of Disperse Dye . Carrier : The extreme crystalline nature of polyester fibre creates problem in obtaining dark shade by conventional dyeing method even at high temperature. The carrier […]
Disperse Dye for Polyester | Why called disperse dye | Application and mechanism of disperse dyes | Features of of disperse dyes
Part 1 : Disperse Dye for Polyester | Why called disperse dye | Application and mechanism Part 3 : Auxilaries Of Disperse Dye Why called disperse dye Disperse dye are the smallest dye of all dyes. They are insoluble in water. When they are applied to the dye bath, they form dispersion. They are free from ionized group. So they have low […]

Melt Spinning , Dry spinning and Wet Spinning Method
Man-made fibers are manufactured by spinning the polymer. There are three major types of spinning process. They are-
█ Melt Spinning (It is used for polymers that can be melted easily.)
█ Dry Spinning (It involves dissolving the polymer into a solution that can be evaporated.)
█ Wet Spinning (It is used when the solvent can’t be evaporated and must be removed by chemical means.)
