Embodiment 1
[0015] After dispersing and mixing 55wt% superabsorbent short fibers and 45wt% wood pulp fluff short fibers, press 35g / m 2 From the separator to the former. Adopting wind-force airflow forming technology, the airflow containing fiber clusters enters the sieve drum type forming head in a laminar flow, and is stirred and dispersed by the sieve drum and the nail roller in opposite directions, so that the fiber clusters are dispersed into single pieces under the stirring action of the nail rollers The fibers are constantly rotating, and the fibers pass through the holes of the sieve drum, and are adsorbed on the forming net under the action of vacuum suction under the forming net to form a uniform fiber web. The short fibers are air-laid, and then sprayed with latex or hot-melt glue to bond the fibers. In the experiment, the distilled water absorption ratio of the dust-free paper is 82g / g, and the water retention capacity is 62g / g; the absorption ratio of physiological saline is ...
Embodiment 2
[0017] After dispersing and mixing 55wt% superabsorbent short fibers and 45wt% wood pulp fluff short fibers, press 500g / m 2 From the separator to the former. Adopting wind-force airflow forming technology, the airflow containing fiber clusters enters the sieve drum type forming head in a laminar flow, and is stirred and dispersed by the sieve drum and the nail roller in opposite directions, so that the fiber clusters are dispersed into single pieces under the stirring action of the nail rollers The fibers are constantly rotating, and the fibers pass through the holes of the sieve drum, and are adsorbed on the forming net under the action of vacuum suction under the forming net to form a uniform fiber web. The short fibers are air-laid, and then sprayed with latex or hot-melt glue to bond the fibers. In the experiment, the distilled water absorption rate of the dust-free paper was 88g / g; the water retention capacity was 67g / g; the absorption rate of physiological saline was 34...
Embodiment 3
[0019] After metering and opening 55wt% superabsorbent short fibers, 10wt% wood pulp fluff short fibers and 35wt% thermoplastic short fibers, the three enter a pulverizer for pulverization and uniform mixing. After the above raw material components are dispersed and mixed evenly, they are sent to the molding machine by the separator. Using wind-force airflow forming technology, the airflow containing fiber clusters enters the horizontal forming head through the air port, and is stirred by two sets of stirring dispersers rotating in the same direction, so that most of the fiber clusters are dispersed into single fibers, and the dispersed single fibers are in the Under the action of vacuum suction under the forming net, the gram weight of 300 grams per square meter is absorbed onto the forming net through a round-hole flat vibrating screen to form a uniform fiber web. The formed fiber web is transported to a hot oven for hot air penetration to melt the low melting point thermopl...
