How is polyester fibre made?
Answers
Answer:
The process of creating polyster fibre begins with reacting ethynele glycol with dimethyl terephthalate at extreme heat. This reaction results in monomer. This monomer is then reacted with dymethyl terephthalate again to create a polymer. The molten polyster polymer is extruded from the reaction chamber in long strips and these strips are allowed to cool and dry and then they are broken apart into small pieces. The resulting chips are melted again to create a honey-like substance, which is extruded through a spinneret to create fibres. The resulting polyster filaments may be cut or reacted with various elements to obtain the correct end result.
Answer:
Synthetic polyester is made using a chemical reaction involving coal, petroleum, air and water. This material is made up of purified terephthalic acid (PTS) or its dimethyl ester dimethyl terephthalate (DMT) and monotheluene glycol (MEG).
