Fibres in your Clothes, at Home, in Town...

The way the fibres are spun, or knitted together,  or dyed and finished,  depends on a series of properties in their chemical structure- the macromolecular design of the fibre. 

They can be arranged into filaments, string, or rope, used as a component of composite materials, or matted into sheets to make products such as paper or felt. Fibres are often used in the manufacture of other materials.

In the case of fibres in garments, they should be : attractive - visually, - to the touch,- in the way the material falls, protect from the heat/cold/water, easily cared for, be comfortable and long-lasting On the other hand they also need to be resistant to: organic solvents and dry-cleaning products, perspiration, cosmetic products, bleaching agents, acids, alkalis and other substances.

As regards the Home: Fibres need to be such that they are not too affected by heat/humidity, that they be stable at high temperatures, at being tumbled in the washer (hydrolysis and oxidation) and to being exposed to the elements.
Clothes for industrial use need to be specifically satisfactory with regard to traction, to using different agents, to be durable  and to protection.

This information might seem quite technical,  The idea I want to transmit is that when we buy clothes we need to take into account, not only the price and what the garment looks like, but also the durability, the characteristics and the resistance of the fabric (eg, viscose)
