Haciendas are big houses where the owners would stay (but not live) while they kept an eye on their workers working the land and or making products. The Spaniards taught the Mayans how to spin the rope together to make thicker ropes and store it on spools that were bigger and stronger. The Spaniards also exported it all over the world and as their production grew they built machines to automate the process further. Teamwork, people.
