Abstract

The objective of the project was to develop low energy pathways for desizing, scouring and bleaching of cotton and polyester/cotton by means of reducing processing times, temperatures, and water and by combining processing stages, and to investigate improvement of impregnation, activation of chemical reactions and foam ? application by dint of presteaming of the fabric. The following results were obtained: In a steam purge unit, fabric runs countercurrent to the flow of steam; subsequent immersion in solution leads to instantaneous and uniform impregnation. Combination of desizing, scouring and bleaching were combined in one energy and water consumption reducing process. In all, an acceptable preparation of fabrics with energy consumption as low as 3.4 GJ/tonne was obtained. Attempts to develop a continuous process were only partially successful because it has not been possible to identify an optimized procedure. Preliminary work was carried out with organic stabilizers: On cotton fabric, the results indicated a beneficial effect for single-stage preparation. On polyester/cotton their use was more effective than sodium silicate and fabric preparation was similar to, or even better than, conventional preparation.
