Disposable diapers were introduced in 1940 and it took a few years for them to become popular.

The disposable diaper is basically composed of the top layer, middle layer and absorbent core.
The factory begins with the introduction of super-absorbent polymer particles, which will form part of the core of the disposable diaper. The pulp is uncoiled in this same chamber.
A spray of water is squirted onto the bead to prevent electrostatic, which would interfere with fabrication.
Internally, the pulp is mixed with the super-absorbent polymer. The result is this soft, absorbent material that will be the core of the diaper.
Rotating drums turn the soft material into a fabric. The guides fold the fabric and the next piece of equipment seals with hot adhesive.
The absorbent core must still be compressed by a set of rollers, so that it is thin enough in the diaper to keep the baby comfortable. The cutting cylinder cuts the core to the correct size for the diaper.
In another sector of the factory, the plastic film goes around the guides and mixes with another type of fabric. The machine glues the layers together to form the outer diaper.
Other equipment installs the elastics in the diaper. They are placed so that there is no leakage on the baby's legs and waist.
Each disposable diaper has these flaps, which are stamped by this rotating cylinder.
This other cylinder joins the outer layers, giving it its shape.
The absorbent core adheres to the rest of the diaper in the machine.
A computerized system monitors the manufacture of each part.
It takes less than half a second for each diaper to be made.
Here we see in more detail each part of the disposable diaper.
The diapers go through guides that fold the flaps and sides. They are then cut individually.
Once again, they are compressed. The paddles fold them in half.
A conveyor system transports them to a carousel.
On the carousel, they are separated and positioned for packaging.
Robotic arms separate the correct amount of diapers. And push for packages.
The same equipment seals diaper bags.
Each diaper has an incredible ability to absorb liquid.
The secret is precisely the super-absorption particles, which act like small gel sponges, which expand according to their absorption.
If you cut the wet diaper, you will find that the liquid has turned into solid particles.
