Leno Weaving - Easy and Fast

Technical textiles and home furnishings include fabrics that must be manufactured in open-fabric constructions, but while remaining slip-resistant. These are referred to as leno

fabrics. Known manufacturing processes only permit low speeds. Dornier's system "EasyLcno" (patent applied) is a new development in leno technology bringing up to 100% higher performance potential on Dornier weaving machines. The system is available for both Dornier air-jet and rapier weaving machines.

Leno Technology

Weaving a normal fabric warp ends lay parallel and cross over or under the filling thread, whereas the warp ends are themselves crossed as well during leno weaving. That means, leno fabrics comprise a warp end and filling thread system just the same as normal fabrics. However, the warp end system is split into straight and looping warp ends. Straight warp ends are always under the filling threads and represent the lower shed during weaving. On the other hand, looping warp ends are always above the filling threads and represent the upper shed during weaving. Leno fabric cohesion is attained by positioning looping warp ends once on the left and once on the right of straight warp ends of a leno group. This leno interlace supports leno fabrics with non-slip, latticed cloth designs with open fabric construction in warp and filling direction.
