Technical Field
The invention relates to the technical field of filter paper, in particular to fiber filter paper for disposable medical and sanitary products and a manufacturing method thereof.
Background
Most filter paper consists of cotton fibers and is manufactured by different methods according to different purposes; because the material is made of fiber products, the surface of the fiber product is provided with countless small holes for liquid particles to pass through, but solid particles with larger volume cannot pass through. This property allows the separation of liquid and solid materials that are mixed together.
Filter paper can be generally classified into qualitative and quantitative. In analytical chemistry applications, the residue collected on the filter paper after the inorganic compound was filtered to separate the precipitate can be used to calculate the run-off rate during the experiment. The qualitative filter paper is filtered to generate more cotton fibers, so that the qualitative filter paper is only suitable for qualitative analysis; quantitative filter paper, especially ashless grade filter paper, is more effective against chemical reactions through a particular treatment procedure, and therefore produces less impurities and is useful for quantitative analysis. In addition to filters for general laboratory use, there are many uses for filters for both life and engineering. Coffee filter paper is one of the widely used filter papers, and the filter paper on the outer layer of the tea bag provides high softness, high wet strength and the like.
