Embodiment 1
[0114] 1% of surfactant (decyl glucoside, trade name "Mydol 10") manufactured by Kao Corporation was sprayed on defibrated pulp fibers (average length 3 mm, diameter (major axis) 10 to 30 μm, NB416 manufactured by Weyerhaeuser) The solution was diluted with water so that 0.6 parts by weight of decyl glucoside was attached to 100 parts by weight of pulp fibers. Then, the temperature was 80 degreeC, and the relative humidity was 3% of air-supply constant-temperature dryers, and it was left to dry for 2 hours. After drying, the pulp fibers were adjusted to predetermined dimensions (75 mm in width, 200 mm in length, and 2 mm in thickness) to obtain an absorbent core. The weight per unit area is 16g / m 2 The absorbent paper (covering sheet) made of pulp fibers covers the skin-contacting and non-skin-contacting surfaces of the absorbent core to obtain a weight per unit area of 200 g / m 2 the absorber. In the obtained absorbent body, 0.5 parts by weight of the surfactant adhered t...
Embodiment 2～22
[0116] According to Example 1, on 100 parts by weight of the same defibrated pulp fibers as those used in Example 1, the surfactants of the types shown in Table 1 were attached in the amount shown in Table 1 and dried. The dried pulp fiber was mixed with 30 parts by weight of a superabsorbent polymer (Aqualic CA-4 manufactured by Nippon Shokubai Co., Ltd.), and adjusted to a predetermined size (weight per unit area: 168 g / m 2 , a width of 75 mm and a length of 200 mm) to prepare an absorbent core as a pulp fiber / superabsorbent polymer hybrid sheet. The weight per unit area is 16g / m 2 Absorbent paper (covering sheet) made of pulp fibers covered the skin-contacting surface and non-skin-contacting surface of the absorbent core obtained to obtain a basis weight of 200 g / m 2 pulp fiber / superabsorbent polymer hybrid absorbent.
[0117] Using this pulp fiber / superabsorbent polymer hybrid absorbent instead of the absorber in Example 1, a sanitary napkin was produced in accordance wi...
Embodiment 23
[0119] 90 parts by weight of defibrated pulp fibers used in Example 1 and 10 parts by weight of rayon fibers (10 to 20 mm in length and 10 to 24 μm in diameter (major axis)) were mixed, and the surface used in Example 1 was sprayed. As an active agent (decyl glucoside 1% water dilution liquid), 0.6 weight part of decyl glucoside was attached with respect to 100 weight part of mixed fibers of pulp fiber and rayon fiber, and drying was carried out as in Example 1.
[0120] A sanitary napkin containing a superabsorbent polymer was produced in accordance with Examples 2 to 22 except that the mixed fiber was used as the fiber to which the surfactant was adhered.
