Besides Wood Cellulose, purified Cotton Linters are the biggest and most important source of chemical Alpha Cellulose. Compared to 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 it comes to manufacturing high-quality products, such as tissue, gazes, high-quality paper for bank notes, Nitrocellulose and Cellulose Ethers.
The raw Cotton Linters, which are a by-product of the cotton-fibre industry, are made into purified Linters (Chemical Cotton) by mechanical cleaning, kier-boiling with Soda Lye, and bleaching steps. In this way, mechanical impurities, waxes and fats are removed and the fibre itself is brightened, while care must be taken to maintain the chemical reactivity of the fibre throughout the process.
MEISSNER has been working in the field of Raw Linters Processing for many decades now and has successfully developed its own process for the manufacture of high-quality Chemical Cotton - an ideal raw material for the production of Nitrocellulose, Cellulose Acetate, Viscose, and Cellulose Ethers such as CMC, MC, HEC, HEMC, HPMC, and HPC.
An optimised process design (counter-current flow of the process water) makes it possible to minimise the consumption of fresh water and chemicals like Soda Lye, bleaching agents and additives, as well as the effluent volume, while at the same time boosting the product quality.
The process offered by MEISSNER thus represents cutting-edge technology in the field of Linters Processing.
