There is provided a method of manufacturing a woven textile, in which a plurality of warp yarns is interlaced with a plurality of weft yarns. A selvedge is formed by interlacing a first subset of the warp yarns with a first subset of the weft yarns and interlacing a second subset of the warp yarns with a second subset of the weft yarns. The first subset of the warp yarns is not interlaced with the second subset of the weft yarns and the second subset of the warp yarns is not interlaced with the first subset of the weft yarns. The method may be used to manufacture a multilayer textile.

Provided are a cloth and a protective product, which allow for any color appearance and have excellent protection performance against electric arcs. The cloth has a woven fabric structure, wherein a front-surface spun yarn containing an infrared absorber- and/or electrically conductive agent-containing fiber and not containing carbon is located on a front surface, while a back-surface spun yarn containing a carbon-containing fiber is located on a back surface, and the cloth has an ATPV value of 8.0 cal/cm.sup.2 or more in Arc Resistance Test ASTM F1959-1999.
