Is alpaca wool/ fur kosher?
The wording of your question is not clear to me. All wool is kosher, however there are some kinds of wool that may not be mixed into a garment together with linen, which is called “shatnez”. Shatnez only applies to the wool of sheep, etc. but not to the wool of camels and other species, therefore shatnez would not apply to the wool of an Alpaca, which is a type of camel.
