And felting occurs when wool rubs against itself.

当羊毛与自身摩擦时，就产生毡化现象。

Any hair over four inches in length is put through a needle felting machine first.

任何长度超过四英寸头发都过针刺毡机。

Then you're asked to separate short and long hair, free it of any debris, put it in an envelope and mail it to the nearest donation felting site.

然后你被要求将短发和长发分开，去除任何碎屑，将其放信封中并邮寄到最近捐赠毛毡站点。

The water still moves through it, so it still comes clean, but you don't have the problem of, you know, it abrading, which - or in that case is felting.

水仍然流过它，所以它仍然是干，你知道，它不出现磨损问题，或者在这种情况下是毡状。

The program allows you to set up your own hair mat-making factory in your own location and all the supplies and materials like the felting machine to each partner.

该计划允许您在自己位置建立自己发垫制造工厂，并将所有用品和材料（如毛毡机）提供给每个合作伙伴。

But the hair and fur is received at one of about 30 donor felting sites around the world where it has left alone and stored for at least a month.

是，头发和毛皮是在全世界大约30个供体毡桩站点之一接收，在那里它已经单独放置并存放了至少一个月。
