For most people, a pair of trousers is made of fabric – but for those who work in the industry, there are many different types of fabric: twill, canvas, corduroy, etc. Then there are combinations of fibres. Most people are no doubt aware that there is a difference between wool and cotton and also perhaps have an opinion as to what kinds of fabric they prefer.
The combination of fibres, the way the fabric has been woven and how tough the fabric is are what gives the fabric its own particular look.
