The weft surface is the face or wearing surface of the cloth.
The thread spun by the jenny could not, however, be used except as weft, being destitute of the firmness or hardness required in the longitudinal threads or warp. Arkwright supplied this deficiency by the invention of the spinning-frame, which spins a vast number of threads of any degree of fineness and hardness.
Raising-cloths are of various kinds and may be merely mediums with a heavy weft, or "condensor" weft made from waste yarns.
The bottom of the cell is formed by those threads and picks which weave "plain," while the ascending sides of the figure are formed by the gradually increasing length of float of the warp and weft yarns.
Fancy cotton goods are of great variety, and many of them have trade names that are used temporarily or occasion produced on the surface of the cloth by needles placed in a sliding frame; lustre, a light dress material with a lustrous face sometimes made with a cotton warp and woollen weft; zephyr, a light, coloured dress material usually in small patterns; bobbinnet, a machine-made fabric, originally an imitation of lace made with bobbins on a pillow.
