Cold Pad Batch Preparation Technology
topic
Cold pad batch preparation impregnates fabric with concentrated caustic soda, hydrogen peroxide, and surfactant at room temperature through a padder and batches it on rolls wrapped in plastic film for 8 to 24 hours, allowing chemical reactions to occur without steam energy consumption, with CPB reducing energy use by 60 to 80 percent compared to continuous steamer scouring-bleaching while achieving comparable preparation quality for medium to heavy cotton fabrics.
Role
Reduces the energy and water consumption of cotton fabric preparation through the elimination of continuous steamer heating by using extended room-temperature chemical reaction time instead of steam acceleration, with CPB being particularly suitable for medium to heavy woven cotton fabrics where the capital investment in batch rolling equipment is justified by the significant reduction in preparation energy cost compared to continuous range operation.
