The Development History and Composition of Adult Diaper

Ⅰ. The development history of adult diaper


No matter how beautiful the beauties are, no matter how great they are, they all have infancy, and they have had uncontrolled bladders. As their intimate partners in infancy, diapers have not been able to accompany their glory to receive even the slightest compliment.


Aerospace experts said that diapers were originally designed for astronauts to urinate in space. Later, adult diapers were converted to civilian use. In fact, diapers have come a long way before they become wet.


It was the Japanese who started to try diaper substitutes. The reason was simple. During the Second World War, Japan lacked natural materials.


The one who took a substantial step was the Swede Borisholm. In 1942, he invented a two-piece adult diaper. The outer layer is plastic pants and the inner layer is an absorbent pad made of paper.


This one-time one is easy to break, and the debris will cover the child's buttocks, so it has not been widely used for a long time.


On April 12, 1961, Gagarin, the first space hero of mankind, had an episode before going into space. When he was about to step into the launch capsule, Gagarin suddenly felt urinary urgency. He had no choice but to do so. He had to get down, leaning on the wheel of a car, and draining the urine down the tube of the spacesuit.


On May 5, 1961, Shepard, the first American astronaut to travel in space, also encountered a problem of urinary urgency. The commander ordered him to urinate in a space suit. It was a risk, because the heat of the urine might make the equipment that must be kept fresh in the space suit failed. Fortunately, the urine cooled quickly, and the tragedy did not happen.


It was not until the 1980s that the space suit was improved, polymer absorbents were added, and an adult diaper capable of absorbing 1400 ml of water was invented. Peeing no longer became a major problem for astronauts.


In the TV show at the time, the diapers of the astronauts were cut into pieces and thrown into the fish tank to show their strong water absorption.


At this time, adult diapers have been updated to the fourth generation, with strong water absorption capacity.


With the continuous improvement of production technology, adult diapers have been improved from the single function of leak-proof and urine absorption from the beginning to not only leak-proof, breathable, but also absorb urine and antibacterial, and add stretchable elastic waist circumference, three-dimensional leak-proof partition, etc.


Ⅱ. The structure of adult diaper

Left and right stickers: The inner film of the left and right stickers is coated with a layer of silicone oil. When the left and right stickers are peeled off, the glue will not transfer to the inner film. It is used in conjunction with the front waist stickers to play a fixed role.


Diversion layer: a new type of thermal bonding composite fiber, which has the function of diversion, helps the urine to diffuse and keeps the surface dry.


Hydrophilic cloth: 100% polypropylene material for adult diapers, a kind of ultra-fine fiber cloth drawn by hot air flow. Because of its special molecular structure, it has a large surface area and can absorb liquid, move and diffuse by capillary phenomenon.


Consisting of continuous filaments, it has good breaking strength and elongation. It acts as the surface material of the product and also has a dry effect.
