Why are cotton and woolen clothes are rough while silk and nylon clothes are smooth to touch?
Dear student,
Woollen and cotton contain air spaces in it which makes it rough when you touch and also they have uneven surface which makes them rough to touch. On other hand silk and nylon have plain long fine structure which makes it appear smooth in touch.
