Method for adding chemicals to a nonwoven material |
摘要 |
A method of adding a chemical additive to a fiber web of nonwoven material including cellulose pulp fibers and synthetic fibers and/or filaments. A hydrojet liquid including the chemical additive is used in at least one hydrojet treatment step, which includes at least one vacuum collecting box. The hydrojet liquid is applied to the fiber web for penetrating the fiber web at a pressure of at least 5 bar but not more than 100 bar, in such a manner so that the chemical additive is penetrated into the fiber to fiber intersections of the nonwoven material.
