Wetlaid fiber preparation
Technology for fiber conveying, screening, blending, refining, storing, and dispensing
After the fibers are suspended in water, the mixture is pumped to the headbox of the inclined wire section to form the wetlaid nonwoven sheet. Various types of fibers (natural and synthetic) can be combined in almost infinite combinations for specific applications.
The illustration shows a stock preparation system combining synthetic and cellulose fibers.
