Alpaca fleece is the natural fiber harvested from an alpaca. There are two different types of alpaca fleece. The most common fleece type comes from a Huacaya. Huacaya fiber grows and looks similar to sheep wool in that the animal looks "fluffy". The second type of alpaca is Suri and makes up less than 10% of the South American alpaca population. Suri fiber is more similar to natural silk and hangs off the body in locks that have a dreadlock appearance.[1] While both fibers can be used in the worsted milling process using light weight yarn or thread, Huacaya fiber can also be used in a woolen process and spun into various weight yarns. It is a soft, durable, luxurious[2] and silky natural fiber.
While huacaya fiber is similar to sheep's wool, it is warmer, not prickly, and has no lanolin, which makes it hypoallergenic.[2][3] Alpaca fiber is naturally water-repellent and fire resistant.[4] Huacaya, an alpaca that grows soft spongy fiber, has natural crimp, thus making a naturally elastic yarn well-suited for knitting. Suri has no crimp and thus is a better fit for woven goods. The designer Armani has used Suri alpaca to fashion men's and women's suits.[5] In the United States, groups of smaller alpaca breeders have banded together to create "fiber co-ops," to make the manufacture of alpaca fiber products less expensive.
The preparing, carding, spinning, weaving and finishing process of alpaca is very similar to the process used for wool.
