in fibre, a non-linear configuration, such as a saw tooth, zigzag or random curl relative to the fibre axis. In woven fabrics, non-linear yarn configurations caused by three-dimensional displacements such as the zigzagging of warp yarn over fill yarn. Most synthetic fibres, both staple and filament, used in carpets is crimped. Fiber crimp increases bulk and cover and facilitates interlocking of staple fibres in spun yarns.
