Answer 2

In dry climate, the cotton-threads will break quickly during spinning. Machine halts, you’ve to join the threads again to restart operation=not good for mass production.on the other hand, humid climate= thread will rarely break. So, cotton textiles were setup near costal areas. (e.g. Mumbai, Osaka, Lancashire).Today we’ve humidifiers that can artificially increase the air-moisture in factory/workshed= you can setup factory anywhere, run it efficiently, irrespective of climate outside.
