It is another name for the fabric bucarán or bocaran (tarlatana), which in the Middle Ages was a fabric of thick and coarse thread, although later it named a linen or cotton fabric finer and more expensive, but already at the end of the fourteenth century it was a common fabric and of popular use. Today it is made from gummed hemp thread and used as interlining and armor for hats and caps. The name comes from Bokara, where this and other fabrics were made, which gave rise to many variants and confusions between them when mentioning them.
