Most time a lot of people do not pay attention or try to read the labels on the materials they're purchasing at a tailor's shop or even in the supermarket. There are various types of material-fibres available for different uses these day but many of them have their advantages and disadvantages and here are the strength test and the burning tests of the international mostly used fibres.
1. Cotton - it is strong when dry, it is about 20% stronger when wet. It burns in and out of flame and fume smells like burning paper. It leaves very little grey or white powdery ash.
2. Linen - it is stronger than cotton, it increases in strength by about 20% when wet. It is similar to cotton.
3. Wool - it loses strength when wet. It does not burn but smoulders; it gives smell of burning hair or feathers; it leaves a bead of porous carbon that is crushable.
4. Silk - it loses about 20% of its strength when wet. It is very similar to wool in themes of burning effects.
5. Viscose rayon - it loses strength when wet. It is very similar to cotton in burning effects.
6. Acetate - it loses less strength than viscose when wet. It burns like cotton. It gives a faint smell of acetic acid or vinegar and its fumes smell like boiling celery.
7. Nylon - it loses no strength when wet. It shrinks from flame; it melts into a hard white or grey bead. It fumes smell like boiling celery.
8. Polyester - it loses no strength when wet. It shrinks from flame; it melts giving a slightly sweet or an aromatic smell and a round, hard black bead is formed.
