Master Synthetic Fibres & Plastics in One Shot | Chemistry - Class 8th | Umang | Physics Wallah

[@pw-123]

Nylon is the first completely synthetic fibre because it was marketed simultaneously in New York and London that's why it is named as nylon. ny stands for new York and lon stands for London

[@adityaraj5921]

No sir Nylon-nyl was arbitrary and 'on' comes from the suffixes "cotton and rayon"

[@unal8120]

Ny means newyork Lon means london
