Document Summary
Inroducion o basic fibre chemisry the chemical composition of a bre gives the bre its unique properties cotton and ax are made up of cellulose molecules, but have slightly different properties. Their properties that are similar are because they have the same chemical make up wool and silk are made up of protein molecules. Have similar qualities, but differ more than cotton and ax because protein is made up of a lot of different smaller molecules that create the whole. Synthetic bres differ from natural bres in chemical composition and from other synthetic. Bres polyester can be quite odour retaining, synthetic bres are more smelly usually than natural. Bonding different types of bonding will occur depending on the properties of the atoms/molecules being joined, bonding occurs between: Different sections of the polymers to make the polymers more stable. The molecules in the polymer with other molecules - water, dyes, etc.
