Alpacas have wool like sheep. This wool is sheared off each year, causing no harm to the animal.
Alpaca fiber comes from their fur. They have a very soft coat.
it's complicated well its fur or wool that comes from alpaca its not really complicated ones you think about it
Alpaca fur is more valuable than llama. Though, some llama hair is of higher quality than alpaca.
You can't make a coat out of a pile of fur. You'd just have hair.
Wool from sheep is often used in spinning, alpaca is also favored.
If you mean what sound does an alpaca make when they call, they hum.
There are many places, but one I recommend is www.peruhandicraft.com Some fur shops have alpaca products, as well as in many flea markets. If you plan on going to Peru any time soon, Alpaca fur is one of their main exports. Also, ordering from Peru works, too.
They kill them for their fur.
You can make many types of clothing. Pretty much anything that you can make with another material such as cotton. An alpaca's wool is very warm
Just like sheep, the wool of an alpaca can be used to make really soft yarn.
You can shave the animals and make sure that after you shave them they are kept warm. They will be very cold without all their thick fur! But there is no need to kill them. As for an actual place to sell the fur I have no answer.
It is only good in the sense of our (humanity) survival. Otherwise, it is bad just to kill an animal for their fur because we already have clothing made from cotton and other materials, therefore humans do not need fur coats or apparel. We only need to kill animals for food, not for fur. It is bad to kill for fur, but good for humanity to kill for food.
