This is a video from www.youtube.com which shows the chemical process of making Nylon. It shows a scientist winding it around for metres and metres - incredible how much you can make. The disadvantages of Nylon is that it is not very Eco friendly as it pollutes water and is hard to dispose of after the cleaning process. Also chemicals are used so it can react with other elements in the air to pollute the environment. I have learnt a bit about Man made fibres- especially Nylon and wouldn't use it it for Eco friendly reasons but the alternative would be polypropylene making it safer and better for the environment.
