Abstract

The invention discloses a production process for fluff pulp for a pad core layer in a sanitary pad. The production process specifically comprises the steps that needlebush is selected as a raw material for preparing the fluff pulp, the needlebush is cooked, bleached and sterilized, and then a bleached needlebush pulp board is obtained; the needlebush pulp board is torn into small pieces, and the small pieces are soaked and subjected to defibering at the normal temperature; sodium hydroxide alkali liquor is added into the sizing agent according to a certain proportion; then, the sizing agent is subjected to microwave processing, medium baking temperature is selected for microwave, the processing time is 3.5 min; after being subjected to alkalization processing, the sizing agent is washed till pH is neutral, after defibering is completed, paper manufacturing with pulp and squeezing are carried out, a half-dry blanket is changed after squeezing is completed, and the dry degree of finished paper reaches 43%-45%; and the wet paper is dried on a glazing machine, and after being dried, the pulp board is arranged in a sealing bag so that water can be balanced. According to the fluff pulp obtained through microwave method alkali processing, the pulp board evenness, the dry bulkiness after gigging, the fluff pulp tightness, the burst index, the imbibitions index and the imbibitions time are obviously improved, and the stability of the pad layer is improved.

Description
