A high-permeability of the method of making backing

The present invention relates to a method for manufacturing a high air permeability of the liner, softwood pulp into the pulper, pulping and pumped into the long-fiber pulp before beating tank after 5.0 ~ 7.0wt% water was added to a concentration of; softwood pulps in long-fiber pulp before beating tank after the water was added to adjust the concentration 4.5 ~ 5.0wt% and by refining the long fiber into the slurry tank knock; the treatment of softwood pulp introduced into the slurry tank; slurry was then pumped into the upper tank, then dried fan pump, and diluted with water to a concentration of 0.2 ~ 0.3wt%, into the paper machine headbox, dispersant, then forming the Internet, dried in vacuo roller press, dryer and dried to a creped paper. Compared with the prior art, such high air permeability of the backing paper is mainly used for the production of paper machine using a dry absorbent core of fluff pulp process and carry the water absorbent resin, it is necessary than normal women's sanitary napkins, baby diapers production the higher air permeability liner with.
