Abstract
The present paper studies the way the reactive derivative monochlorotriazinyl-?-cyclodextrin can be grafted on bast fibres simultaneously with their wet spinning. Process modelling involved simultaneous mechanical and chemical processing, at different parameters of wet spinning-grafting (concentration of monochlorotriazinyl-?-cyclodextrin and speed of the material in the impregnation stage). The mathematical methods of dispersion analysis and regression were applied to obtain optimum values of the process parameters. To attain physico-mechanical characteristics adequate for a 100% hemp yarn and an optimum grafting degree for subsequent inclusion operations, a soaking time of 23.7 sec and a solution concentration of 55 g/L monochlorotriazinyl-?-cyclodextrin are required for simultaneous wet spinning-grafting.
