I have a small alpaca herd, and this is what I do before getting the fiber processed.
First, I skirt the fiber, or sort it by fineness, crimp style & staple length, while removing large contaminants, such as bits of hay, straw, or poop. Once I have that done, it goes into plastic bags until I can get it to the mill to be made into yarn. I leave the tops open, and I put in a dryer sheet to discourage moths.
There are 2 different breeds of alpaca, suri & huacaya. Huacaya fiber is fluffy & similar to wool. Suri fiber is very silky & comes in locks. Due to differences in the fiber structure, suri can be very difficult to spin into yarn on its own. Suri yarn is a lot like silk, very drapey but with little memory.
