A question in GATE 2012 Textile Engineering and Fibre Science Paper with Solution has been updated:
In the context of thermal bonding of nonwoven web, the statement which is not true is
- The polymer flows by surface tension and capillary action to fibre cross over points
- A thermoplastic component has to be present in the web
- Chemical reaction takes place
- Heat is applied until the thermoplastic component melts
