Sliver

A continuous, ropelike strand of loosely assembled fibers without twist that is approximately uniform in cross-sectional area. This is the state of fibers after they have been carded. In this form they may be drawn from the card by the drawing frames and eventually twisted into a yarn. If a fiber is combed as well as carded, this process takes place after carding and before drawing.

Shuttleless Loom

A weaving device that carries the filling yarn through the shed by the use of air or water jets and grippers.

Selvage

The longitudinal edges of a fabric that are formed during weaving, with the weft not only turning at the edges but also passing continuously across the width of the fabric from edge to edge.

Size

A gelatinous film-forming substance, in solution or dispersion, applied normally to warps but sometimes to wefts, generally before weaving, to protect the yarns from abrasion in the healds and reeds and against each other; to strengthen them; and by the addition of oils and fats, to lubricate them.

Shuttle

A yarn-package carrier that is passed through the shed to insert weft during weaving. It carries sufficient weft for several picks.

Shed

The opening formed when warp threads are separated in the operation of weaving.

Section Warping

A two-stage machine method of preparing a warp on beam, consisting in: winding a warp in sections on a reel (drum, mill, swift) and then beaming-off the complete warp from the reel onto a warp beam.
