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.
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!! :)
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.
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.
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
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.
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
The difference between dry chemistry analyzer and the chemistry analyzer is the reagents used.
A dry gallon is frozen.
the difference between dry air and atmospheric air is that atmospheric air contains water vapor but dry air contains no water vapor
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.
Dry corn is dry and soaked corn is wet.
one is dry one is wet
macular degeneration difference between wet and dry
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.

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