The remarkably soft wool of an alpaca. It is very warm.
Alpaca wool is acquired by shearing tamed alpacas - each alpaca can be sheared every 15 days for 100 wool, for an average of 6.67 per day.
It can also be purchased from traders.
Alpaca wool has the second worst protective stats of any textile in the game tied only other wools, and besting cloth only by virtue of proving a significantly more heat armor, though still little in compared to textiles like Devilstrand. Like other wools however, where alpaca wool excels is in cold insulation, offering the 7th best cold insulation of any textile in the game. In comparison, its heat insulation is lacking at tied 10th of all textiles, comparable to many leathers.
Thus, it is almost entirely irrelevant as protective clothing. Additionally, its average heat insulation make it unattractive in hot biomes, except where bulk textiles of any sort are the primary requirement as many leathers are available with equivalent insulation but significantly better protection. Only its cold insulation provides utility in cold biomes, and in many of them other less insulative but more protective textiles will suffice. However, its ease of production and good insulation can make alpaca wool parkas or skin-layer apparel an easy way to provide winter clothing to a colony, and possibly sufficient to avoid sacrificing any other aspects of their outfit. Compared to other wools, which largely fill the same niche alpaca wool is middle tier or above - the alpaca has the second fastest Per Day production rate while only eating as much as a sheep. Alpaca wool also has the middle cold insulation, better than bison or sheep wool but inferior to muffalo or megasloth wool. It also has the best heat insulation of any wool but this unlikely to be relevant as if heat insulation is required, wools generally should be replaced with more protective and equally insulative leathers.
For use in furniture, it only has a somewhat improved beauty factor over other common textiles, but its rapid redundancy as clothing, the ease of acquisition, and modest but not insignificant value makes it a solid choice for improving furniture beauty and providing bulk textiles for construction. As alpacas are the second fastest producers while also tied for the lowest hunger rate of all wooly animals, they are ideal for this bulk production. Care should be taken however as, like other wools in RimWorld, it is exceptionally flammable.
