Multiple plain weave

Reversible double-woven cloth is produced by multiple plain weaving. It is woven in two layers, which may be completely independent, may be joined at one or both selvages, may be held together along the edges of a pattern, or may be united by a separate binding weft. Though often tabby weave is employed on both surfaces, any of the basic weaves may be used, depending on the intended use of the fabric.

Double-woven cloths have been used for clothing, but, though warm, they tend to be heavy and to drape poorly. They are most often used as bedcovers or wall hangings. German 18th-century Beiderwand is an example of antique double-woven cloth consisting of two layers of tabby weave joined only along the edges of the pattern. A dark-coloured pattern in one layer is set against the light-coloured ground of the other layer; the pattern is seen in negative or the reverse side of the cloth.

Nonreversible cloth with two or more sets of warp and sometimes of weft can also be produced. These cloths have an intricately patterned face, and all warps and wefts that do not appear on the face are carried along and bound into the web on the reverse side. This class includes important historic textiles, such as early Persian and Byzantine figured fabrics, as well as more recent Jacquard-woven imitation tapestries and a wide range of imitation brocaded fabrics.

Pile weave

Pile weaves have a ground fabric plus an extra set of yarns woven or tied into the ground and projecting from it as cut ends or loops. A great range of textures is included in this binding system, from terry pile toweling and corduroy to silk velvets and Oriental rugs.

In warp-pile fabrics the pile is formed by an extra set of warp yarns. To create such a fabric, first one set (sheet) of ground warps is raised, and the weft makes its first interlacing with the ground warp. Next, pile warps are raised, and a rod is inserted through the entire width of the web. The remaining ground warps are raised to form the third shed; then the ground weft is shot across again. This sequence is repeated several times; then the rods are slipped out, leaving a warp pile. To form cut-pile velvet, a knife on the end of the rod cuts the pile warps it passes, creating two fine rows of cut pile. Although the system has many technical variations, the same basic process can be applied to most warp-pile weaving.

If the pile is not cut when the rod is removed, a loop pile fabric results. In weaving terry pile fabrics, the ground warp is under tension, and the pile warp stays slack. When wefts are beaten in, the slack yarns are pushed into loops on both sides of the cloth.

To make velvets by double-cloth construction, two layers of cloth are woven simultaneously face-to-face, with long pile warp yarns connecting the two layers. After the cloth is woven, a knife slices the two layers apart.

Corduroy and velveteen are weft-pile constructions. Weft yarns having long floats are inserted between ground-weave picks. The floats are slit longitudinally after the fabric is completed, thus forming a ribbed surface of cut pile. In manufacture of velveteen the floats are formed over the whole surface of the fabric and cut evenly to imitate velvet.

Hand-knotted Oriental and Scandinavian rugs are constructed on a tabby-weave ground, with each row of knots followed by tightly beaten-in wefts. The pile of fine Oriental rugs may contain 160 knots per inch, thus completely obscuring the knots in the rug’s foundation.

Inlaid weave

In all of the fabrics of this class, designs are created by inserting pattern warp or weft yarns between ground warps or wefts.

Brocaded fabric has a pattern of coloured or metallic threads, or both, set in low relief against the ground weave. The ground weave can be any basic weave, since the brocaded pattern is merely inserted between ground wefts and is bound by ground warps. Until the advent of the Jacquard mechanism in the early 19th century, brocaded fabrics were woven by drawloom weavers who inserted the pattern wefts by hand. These weft yarns were wound on small brocading shuttles that travelled across the width of each pattern repeat, a separate shuttle being used for each colour in the repeat. Generally, these extra wefts were found only in the area in which the pattern was located and usually formed long floats on the reverse side of the fabric.

A mechanical process closely corresponding to hand brocading is called swivel, a system of figuring fabrics by using mechanically controlled pattern shuttles. The figures, inserted between ground-weft picks, interlace with the warp. The lappet system produces figured fabrics resembling those made by swivel figuring, but the pattern yarns are extra warps (rather than wefts) brought into play from separate warp beams. Lappet weaving is generally confined to coarse pattern yarns and can be distinguished from swivel by its interlacing with weft rather than with warp yarns.
