Answer:
A fibre is made of polymer chains.
A polymer chain is made up of monomers.
There are bonds between the monomers. There are also bonds between the polymers chains.
When polymer melts, the bonds between chains break first while the bonds between monomers remain intact. This happens to thermoplastic synthetic fibers.
In natural fibres, the bonds between the monomers break first- thus destroying or burning the polymer chains. This happens to thermosetting polymers like cotton- polymer (cellobiose ) ,
