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.)
