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!! :)
What are the differences between wet and dry vacuums?
Wet vacuums hold more weight than dry vacuums. Another difference is speed. Dry vacuums are quicker because they have a wider hose so they pick more things up at the same time.
What is difference between dry heat and moist heat?
Dry heat is the absolute substance temperature without accounting for the modulating effects of water vapor in the substance. Moist heat is the relative substance temperature when accounting for the modulating effects of water vapor.
What is the difference between dry ice and a fog machine?
Fog machines: Not found everywhere No age requirement No harm to skin unless allergic. Dry Ice: Found in grocery store 18 years or older Causes skin burns if left on skin
What is the only difference between a bolt of lightning and the spark that is seen between a person's hair and a hard rubber comb used in the hair on a dry day?
The difference between lightning and static is lightning is formed by giant clouds rubbed against each other and static is something such as flanel p.j.s rubbing together. Lightning is big, and static is small.
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 a wet sieve and a dry sieve analysis?

What is the difference between Dry chemistry analyzer and Chemistry analyzer?
The difference between dry chemistry analyzer and the chemistry analyzer is the reagents used.
What is the difference between a liquid gallon and a dry gallon?
A dry gallon is frozen.
Is there really a difference between ion hair dryers and regular ones, and what is the difference?
Yes, while regular dryers just melt the moisture in the hair, ion hair dryers negatively break down the ions in the water and dry your hair faster.
What is difference between dry air and atmospheric air?
the difference between dry air and atmospheric air is that atmospheric air contains water vapor but dry air contains no water vapor
What is the difference between dry corn and soaked corn?
Dry corn is dry and soaked corn is wet.
What is the difference between a dry and wet objective lens?
one is dry one is wet

macular degeneration difference between wet and dry
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.

Is ice dry?
yes, until it starts to melt. or its dry ice
When does dry ice melt?
Dry ice only melts when it is under pressure of 5.1 atmospheres.
