Definition of alpaca for English Language Learners. : 1  a South American animal that is related to the llama and has long woolly hair. : 2  wool of the alpaca or a cloth made of it.
The question of wool is a very complicated one. First of all, alpaca fleece is divided into two sections. The head, neck, and legs produce coarser, less valuable fleece. Everything else is classified as the blanket, and this is what people actually want. A high quality, fully grown alpaca can produce up several pounds (probably 3 or 4) of blanket per year.
