Sažetak
Reactive Dyes, which are chemically linked to textile substrate, ask for new technological procedures and processes in order to achieve higher yield in the dye fibre interrelation, which means lower water pollution, especially important from the point of view of environment protection. These problems can be solved in a much simpler way by the adequate knowledge of physico-chemical properties of textile fibres and through the determination of the number of functional group present in the fibre, which are responsible for the reaction with the dyestuff. In the chase of cotton, the only responsible-nucleophilic groups are hydroxylic groups, so through their quantitative determination the first phase of technological process rationalisation can be achieved. The paper deals only with monofunctonal reactive dye, of vynilaulphone reactive centre, C.I. Reactive Blue 19, with the aim to determine quantitatively the number of accessible nucleophilic hydroxylic groups. Cotton fibre has been mercerised with NaOH of various concentration. Upon after dyeing, spectrophotometric determination has been used to determine the quantity of the dyestuff fixed, and the number of accessible hydroxyl groups rises for the dyestuff ratio up 2% with slack mercerisation and mercerisation in in-plant conditions. So, prior mercerisation of cotton, having in mind lower degree of water pollution, can be recommended for the dyestuff ratio lower than 2%.
