From http://www.the-ropewalk.co.uk/ks2th2.pdf, pages 9 and 10:
Raw fibres are hatchelled into long straight clean fibres, which are spun into yarn, which is twisted into strands, which are twisted into rope.
Different types of rope are made with different numbers of strands (page 14).
Rope makers are generally called rope makers - there is a detailed explanation of the processes involved at the Barton Ropery Museum.
