Research was carried out to test the use of DMA-AC (1, 1-dimenthyl-3-hydroxy azetidine-chloride) and/or DEA-AC (1,1-diethyl-3-hydroxy azetidine-chloride) to modify cotton, and then to use the modified cotton as an adsorbent of acid dyes. The various factors affecting the rate of adsorption of the dye were studied: the quantity and type of substrate, the concentration and structure of the dyes, the temperature and pH of the bath. The research was carried out using scoured and bleached cotton fabric. It was concluded that many factors can influence the degree of adsorption, eg the solubility and ionization of the dye in solution, the planarity of the structure of the dye, the hydrogen bond and the Van der Waals forces between the dye and the modified cellulose.
