Investigation of new bleaching systems for cotton fabric

A new unconventional bleaching system with non-classical stabilisers of the polymer type is presented, The role of polymer stabilisers is to reduce th e speed of peroxide decomposition and utilisation of the active bleaching a gent in the bleaching solution. The whiteness grade of fabrics (100% cotton ) was measured according to the Berger criterion by a spectrophotometer usi ng appropriate computer software. The degree of whiteness was high, above 8 1% in all cases. The mechanical characteristics were obtained by a dynamome ter, and the breaking strength was slightly smaller than the breaking stren gth obtained for the raw sample. To study chemical changes of the cotton fi bres submitted to intensive bleaching, infrared spectroscopy (Fourier Trans form Spectroscopy - FTIR) was used. The structural and morphological featur es of the cotton fibres after different bleaching regimes were studied by s canning electron microscopy (SEM).
