Optimization of the Conventional Bleaching of Wool with Hydrogen Peroxide

The individual and combined influence on the bleaching of wool of the concentration of hydrogen peroxide, temperature and time treatment have been studied, using a rotatable central design of experiments in which values of the above variables covered the values used in industry. Mathematical treatment of the values the optical, chemical and mechanical parameters has enabled equations to be derived, from which the value of any parameters has enabled equations to be derived, from which the value of any parameter can be computed when the values of the variables are within the range of the plan of experiments, resulting in a good agreement being obtained between experimental and calculated values. Use of these equations facilitates optimization of the process of wool bleaching conditions leading to the whitest wool have been suggested for an allowable chemical degradation
