Gig-mill

[1][2] Examples of the results of gigging are woolen fabrics such as chinchilla, beaver cloth, and melton.

[3] The process involved gradual teasing of the surface to raise the nap.

As with flannelette, the fabric surface is treated with sharp teasels during gigging to elevate the surface fibers, providing hairiness and lustrous nap.

Later, teasels were replaced by metallic wires similar to those used in carding machines.

Examples of napped fabrics include brushed tricot,[6]: 146  and flannelette.
