A review of chemical and physical factors influencing Yankee dryer coatings Gary S. Furman and Winston Su, Nalco Chemical Company, Naperville, Illinois, USA Keywords: Adhesives, Creping, Tissue papers, Yankee dryers, Review. SUMMARY: Various chemical additives are utilized to pro- vide thin adhesive coatings on Yankee dryers during the pro- duction of creped tissue papers. These coatings aid in imparting the desired degree of crepe to the tissue sheet. The creping process is a delicate balance between adhesive and release forces, which has a dominating

Let the paper product guide the choice of mechanical pulp Ingrid Fineman, Swedish Forest Products Research Laboratory, Stockholm Keywords: Mechanical pulps, Properties, Adaption, Print- inn papers, Paper boards, Tissue papers. SUMMARY: Developments in the field of mechanical pulping mean that it is now not only possible but also important in any given situation to tailor the pulp to meet the end-use requirements of the product concerned. For absorbent products chemimechanical pulps are of special interest due to their good absorption properties, low

paper and an adhesive. The pre-aged samples of copper acetate in gum arabic, thick and thin application ( Figures 4 and 5 ) were used to test methods of mechanical stabilization. The Japanese tissue papers were applied to the recto of the printed colour areas and the verso of the thin coloured area (glass rod). In treatments of strongly degraded verdigris it can be necessary to stabilize a tear from the recto side. Due to the water sensitivity of the pigments it was decided to use pre-coated Japanese tissue papers based on research and experience in the treatments

arrived at Wrocław by truck it turned out that during one day they managed to transport not 1,000, but 2,000 volumes of wet books, periodicals and maps. They also organized the transport of 2 tons of frozen books from E. Smol- ka Voivodeship Public Library in Opole and freeze-stored them in Miesiączków. Soon after they started to dry them by interleaving the pages in books with tissue papers. In the Nicolaus Copernicus University Library in Toruń a group of employees dealt with collections from Wrocław while another group in the Scientific Information Department

the case of Nepalese handmade paper coated with CMC and MC the folds were found to be satisfactory even after ageing for 72 hours. In the case of Japanese tissue the folds were observed to be less after ageing. Chiffon coated with many adhesives had the highest folding endurance. In this case the folds were measured up to 3000. and even after accelerated ageing the folds were not reduced below 2000. Only chiffon coated with CMC+dextrine provided a folding endurance below 2000 after accelerated ageing. The Indian tissue papers were found to have good folding

the production of value-added products which include printing and writing papers, newsprint, coated paper and board, and tissue papers. According to the 2006 statistics of the Korea Paper Manufacture’s Association, the utilization rate of recycled fibers for the production of tissue in Korea was about 60%. Although the utilization rate of the recycled fibers as raw materials depends upon the paper grades and manufacturers, it can be as high as 90% for toilet tissue grade. Most of the recycled fibers used in tissue production consist of computer printout (CPO) and

. In a previous study, the possibility of improving the key properties of tissue papers was studied by modifying the kraft pulping process conditions. It was shown that an increase in pulp yield had a positive effect on the strength of low-grammage handsheets, especially at a low degree of refining (Rahman et al. 2017 ). The process conditions were adjusted by addition of polysulfide or NaBH 4 with alkali and sulphide resulting in a yield increase from 48.1 % to 50.2 % and from 48.1 % to 52.6 % respectively. This yield increase was related to an increase in
