I'm sure you've learned a lot about wood fibers from our introduction, but today we're going to take a more technical look at so-called lignin fibers (Methyl Cellulose, or MC), which are chemically treated organic fibers of natural wood. It is by screening, splitting, high temperature treatment, bleaching, chemical treatment, neutralization, screening into fibers of different length and thickness to meet the needs of different application materials. Lignin fibers are treated at temperatures above 260 ° c, so they are chemically stable under normal conditions and do not corrode with common solvents, acids or alkali.
