Textile product quality plays an important role for the consumer in the light of Standard ISO 9000. Different parameters determine the quality of any textile product. Fabrics characterized by a high level of aesthetic appeal should be suitable in appearance and dyeing uniformity. Such properties as fiber maturity and its distribution, number of neps and trash content and size are responsible for this aspect of quality. In 1996, the Institute of Textile Architecture purchased an AFIS system with a module enabling cotton fineness and maturity to be measured. The aim of this research was to answer questions on how methods of maturity assessment according to the GOST standards used so far in Poland and other Eastern European countries correlate with AFIS parameters.
