Colour is the visual perceptual property in the cotton grade classification of Universal Cotton Standards. We undertook an experimental study on the variation in cotton colour using the Non-contact method. Rd (degree of reflectance) and +b (yellowness) are globally recognized colour parameters of cotton, which are measured by HVI (High Volume Instrument). The Non-contact method is used for the evaluation of colour variation within cotton samples. The results obtained from the Non-contact method were compared with those of other conventional methods used globally for the color measurement of cotton fibers. Additionally image analysis is interpreted with the variation in cotton colour. Results confirmed a strong co-relation between the Non-contact method and image analysis for the colour variation of cotton.

Kolor jest właściwością służącą do klasyfikacji jakości bawełny przy zastosowaniu uniwersalnych standardów. W pracy badano zmianę koloru bawełny stosując metodę bezkontaktową, która służy do oceny zmienności barwy wewnątrz próbek bawełny. Otrzymane wyniki porównano z innymi znanymi metodami stosowanymi na całym świecie do pomiaru koloru włókien bawełnianych. Wyniki potwierdziły silną korelację pomiędzy metodą bezkontaktową a analizą obrazu zmian barwy bawełny.
