Anyone can explain to me about this things? What is it for(i mean what nature of stuff)? What is the advantages using this material for some stuff?
Answers:    Polyester is a synthetic Thermosetting Polymer.

In its hardned state, it can be used as a resin for model making, but it can be also be woven into fibre and used as soft insulation material for bedding / sleeping plenty etc.

It is very angelic at an insulator which is why it can put into jackets and duvets to keep hold of us warm.
It is used within the clothing industry, as opposed to for example cotton which grows, polyester is a man-made bran out of a chemical plastic mix.It isn't as good for your skin as raw fibres.
