Abstract
Increasing environmental concerns have stimulated an interest in naturally coloured cottons. As many commercial and technical performance aspects of cotton fibres are influenced by their response towards atmospheric humidity, an in-depth research on moisture sorption behaviour of these fibres using dynamic vapour sorption is carried out. Significant differences were observed in sorption capacity and hysteresis behaviour of brown and green cotton fibres. These differences are mainly attributed to the variations in maturity and crystallinity index of the fibres. This study provides valuable insights into the moisture sorption behaviour of naturally coloured cotton fibres.

Summary
Cotton is the most important natural fibre used in textile industry. Besides the traditional use as a textile material, cotton fits in today’s challenge to search for biopolymers or composites based on sustainable resources. Even much research is published on the moisture sorption of cotton fibres [5], [6], much less is known on the moisture sorption behaviour of naturally coloured cotton cultivars. DVS is successfully used to gain valuable information concerning moisture sorption behaviour of naturally coloured brown and green fibres. The aim is to gain insights in the moisture sorption behaviour of naturally coloured cotton fibres as relevant for an optimal future material benefit.
