Argentina forms part of the scanty group of countries producing and exporting quality wools in the world, actively participating in international markets. The breeding of sheep is extensive and is carried out in several regions, obtaining in each of them wools with well-defined features.

The main producing regions are La Patagonia (Provinces of Santa Cruz, Chubut, Rio Negro, Neuquén and Tierra del Fuego), the province of Buenos Aires and La Mesopotamia (Provinces of Corrientes and Entre Ríos).

Sheep breeds raised in Argentina vary from Merino with wools of 18 mic. And less, or Corriedale, with wools of 27 mic up to wools of the Lincoln type of 40 mic. And more. There are also crossbreeds and those named Criollas. According to the fineness, wools are typified in Fine wool (25 microns and even finer), Cruza Finas (between 25 and 30 microns), Cruza Medianas (between 30 and 35 microns) and Cruza Gruesa (35 microns and more).

Argentina, as a country producing high quality wool, uses such capacity to satisfy export demands with different elaboration degrees, being, in average, similar to the amount exported as greasy wool, scoured and tops of combed wool.
The Province of Chubut forms part of La Patagonia, region located at the southern part of the Argentine Republic, where the raising of sheep is a very traditional activity and is the best economic exploitation alternative for those farms.

The city of Trelew was originated by a group of people arriving from Wales (U.K.) in 1860, and found in the lower valley of the Río Chubut a proper place to maintain their traditions and uses.

To date, Trelew is the main wool industrialization center in Argentina and Puerto Madryn, only 60 km far from Trelew, is the port of departure for most tagonia (Provinces of Santa Cruz, Chubut, Rio Negro, Neuquén and Tierra del Fuego), the province of Buenos Aires and La Mesopotamia (Provinces of Corrientes and Entre Ríos).
