How did machines speed up textile manufacturing

I'm not quite sure what you expect to learn here... Basicall when the machines were started to be used in textile manufactoring, less people were needed to produce a certain amount of goods.

Also manufacturers, as the name suggests, were based on the work of humans (with their hands). The introduction of machines was connected with the growing number of factories, where they are used to produce thigns.

Hope that's what you meant... If not, let me know :)
