 Besides of Wood Cellulose, Cotton Linters are the biggest and most important source of chemical pulp. Compared with Wood Cellulose, Linters offer significant advantages, such as higher purity, higher viscosity, higher brightness, and a lower content of hemi-celluloses. These characteristics make purified Linters the ideal cellulose raw material, when high quality products, such as tissue, gazes, high quality paper for bank notes, Nitrocellulose and cellulose ethers, are to be manufactured.The raw Cotton Linters, which is a by-product of the cotton-fibre industry, is turned into purified Linters (chemical cotton) by mechanical cleaning, kier-boiling with Soda Lye, and bleaching steps. Mechanical impurities, waxes and fats are thereby removed, and the fibre itself is brightened, always under special care that the reactivity of the fibre is not to be reduced. Since many decades Meissner has worked on this field, successfully developing their own process technology for the manufacture of high quality dissolving pulp (chemical cotton). Our process guarantees a high quality of the product, which make it an ideal raw material for the production of Nitrocellulose, Cellulose Acetate, Viscose, cellulose ethers such as CMC, MC, HEC, and HPC. By optimization of the process design, the consumption of fresh water and chemicals like Soda Lye, bleaching agents and additives, as well as the effluent volume, are reduced to a minimum by countercurrent flow of the process water, with the product quality being further improved at the same time. Therefore the Meissner process design presently represents the state of the art in the field of Linters processing. |
