Melt spinning is used for polymers that can be melted i.e. the polymers must have a melting temperature (thermoplastic polymers). Dry spinning is used for polymers that do no have melting temperature and need to be dissolved in solvent (thermoset polymers).
In case of melt spinning, the polymer solidifies by cooling after being extruded from the spinneret. Whereas, in case of dry spinning, the polymer solidifies through evaporation of solvents and this is achieved by a stream of air or inert gas.

Can you melt people?
You as a human cannot melt from heat. The worse thing is that you might get burnt. EXP: An ice cube will melt in heat...I don't think you're an ice cube!! :)
How the dry air increases evaporation?
Dry air increases evaporation because it has a lower relative humidity, which creates a larger difference in vapor pressure between the water surface and the air. This difference in vapor pressure drives the movement of water molecules from the surface into the air, increasing the rate of evaporation.
What Energy transformation that occurs in a clothes dryer?
Mechanical energy from the spinning drum and heating element is transformed into thermal energy to dry the clothes.
Do CD's melt?
Yes, CDs can melt when exposed to high temperatures, typically above 120 degrees Fahrenheit. The heat causes the polycarbonate material of the CD to warp and distort, rendering it unplayable. It is important to store CDs in a cool, dry place to prevent melting.
Why can a spin dryer dry clothes?
They can't, they do however greatly reduce the amount of water left in the clothes after a washers spin cycle. This allows the clothes to dry on the line faster and leaves them softer than "non spinning" as the water left in the clothes is greatly reduced.
What are the most popular spinning processes for synthetic fibers?
The three most popular spinning processes are known as dry, wet, and melt.
What is the difference between Dry chemistry analyzer and Chemistry analyzer?

What is the difference between a liquid gallon and a dry gallon?

What is the difference between dry corn and soaked corn?
Dry corn is dry and soaked corn is wet.

How is lycra made?
Lycra can be made in a few different ways, including reaction spinning, solution dry spinning, solution wet spinning and melt extrusion. With all of these methods, the first step is to cause monomers to react and produce a prepolymer, which is then reacted more to produce fibers.
