A 1932 technical article on the causes of faults in crêpe fabrics made wholly or partly of rayon. It covers weft faults (weft bars, tram lines, lashing-in, box marking), warp faults (slack ends, streaky acetate warps), scouring faults (oil spots, residual silk gum, creasing) and finishing faults (over-tensioning, rain-spotting, slipping, blistering, shrinkage). It concludes that most faults can be avoided with proper care in manufacture. Two photographs illustrate weft bars and a crease effect after dyeing.
