Abstract

A survey of dye batch variation in samples of mass produced textile fibres was carried out on material from textile manufacturers, socks from a national retail chain, and samples from 100 police uniforms obtained from the Tayside Police Force. Using TLC analysis, variation was found in the dye composition of each of the sources of material. Where the dye intensity and fibre diameter were optimal, this variation was detectable in single fibres of 3-4mm length.
