Velvet fabric n. A warp-pile woven fabric with short, dense cut pile that produces a rich fabric appearance and soft texture. Two methods are used for weaving velvets. In the double-cloth method, two fabrics are woven face to face with the pile ends interlocking. A reciprocating knife cuts through these pile ends to produce two separate pieces of velvet. In the second method, pile ends are lifted over cutting wires that are inserted with the filling and that are withdrawn to cut the pile. Kadolph SJJ, Langford AL (2001) Textiles.

It has to be stated that an increase of spacing basically weakens a woven structure because interlacings become less slippage resistant if floatings of threads increase. For this reason, additional threads were inserted locally to the fabric to fill the gaps between woven threads. The special weave design for three-dimensional shell fabrics appears in the next section. 

A typical layer-to-layer interlock weave with Z fibers is shown in Figure 9.44. Z fibers are added to the layer-to-layer interlock weave. The dark circles denote the warp ends and the curved lines show the filling path. Z fibers run through the fabric thickness. In the example figure, Z fibers are perpendicular to the warp, but Z fibers can also be inserted at various angles, such as 30°, 45°, and 60°.
