Textile fibres differ in burning behaviour?

Textile fibres differ in burning behaviour?

Textile fibres differ in burning behaviour because the long molecules from which they are formed differ. Natural fibres may be comprised of a single molecule in a long chain (e.g. cotton) or from many different molecules (e.g. wool). If they are made from simple synthetic molecules they are called polymers.

The physical chemistry of the long chain or polymer will determine differences such as melting behaviour and the reaction to flame will differ according to its physical and chemical characteristics. (See chemical characteristics).

The differences between fibres are often the basis for choice of fibre in a textile according to the properties of the final textile and its use. Different fibres may be combined in a single textile for many reasons including technical performance in use and decorative effects.

It is a problem in flame retarding textiles that mixed fibres with differing characteristics and burning behaviour may conflict to have a significant effect on burning behaviour of the textile. It is possible for decorative textiles to contain as many as 5 or 6 different fibres.
