Absorption core body, hygienic product and preparation device and preparation method of absorption core body

The invention relates to an absorption core body, a hygienic product and a preparation device and method of the absorption core body, the absorption core body comprises a composite fiber net, the composite fiber net is formed by compositing first hydrophilic fibers, second hydrophilic fibers and third bonding fibers, the first hydrophilic fibers are processed and formed through a melt-blowing technology, and the second hydrophilic fibers are processed and formed through a melt-blowing technology; the second hydrophilic fiber and the third adhesive fiber are fed into the leading-in area for compounding through the airflow channel after being opened, carded and lapped, are reinforced and sterilized through the drum-type steam net spraying mechanism, and are combined with disinfection to prepare the sanitary absorption core body. The first hydrophilic fibers are superfine fibers, large in specific surface area and good in water absorption performance and serve as absorption materials of the ...
