FABRIC DEVELOPMENT FOR IMPULSE DRYING

Impulse drying applies heated oil technology using temperatures higher than 150 degrees C to the shoe press technology. With increasing know ledge and understanding of the process, impulse drying is about to eme rge into the paper industry and revolutionize the papermaking process. Over the past several years, significant strides in press fabric deve lopment for impulse drying have been made. The results of the study wi ll show that, with the appropriate press fabric, pressing at elevated temperatures with extended nip residence time is beneficial for lightw eight base-stock. Not only does sheet dryness increase, but improvemen ts in other paper properties occur.
