Cumulative effects of washing on properties of cotton fabrics and their blends

摘要

Apart from removing soils and preventing redeposition, chemical and mechanical activities during washing also change the structure of the textile treated. The intensity of these changes is dependent on the initial level of quality of the textiles treated, as well as upon the processing conditions (temperature, washing agent, mechanical parameters, number of washing cycles, etc). The aim of this paper was study cumulative effects of washing on properties of cotton fabrics and their blends through RAL-GZ 992 quality criteria evaluated through ash content, whiteness, tint deviation, mechanical and chemical damage. Electrokinetic potential, pilling resistance and morphology of cotton and their blends were selected as evaluation criteria for surface characterization of cotton and their blends after multiple washing cycles.
