Generally used to refer to loop pile carpets and bouclé in fabrics. With all Wilton weave carpets, the pile is woven into the construction as loops, and these are usually cut to create the pile. In Brussels weaves, however, the loops are left uncut. The resulting carpet is just as thick and comfortable under foot, with a tighter feel and matt finish, as light does not reflect from a loop as it would from a cut length.
Flemish migrant workers brought the technique to England and to France, hence the name.
