Define the Properties of Fibre?

The structural make up of fibre influences its properties which in turn affects the physiologic and metabolic roles. This is well-depicted in the Figure given herewith.

The polymeric backbones and /or side chain units determines the fibre's 2-dimensional structure, which influences the 3-dimensional structure i.e. how the polymer interacts with itself and other polymers e.g. because of their two-dimensional linearity, cellulose molecules interact with themselves via hydrogen bonding to form crystalline regions.
