What is the difference in alpaca and llama wool?

These different types of wool are produced from two different animals. The micrometer measurement for llama fibres is 30-40, while alpaca fibres measure 10-15 micrometers.

Alpaca fleece is desirable for needlework and clothing while some llama fleece is suitable for carpets and lead ropes. Finer llama fleece is also desirable for needlework.
