The core technology of diaper pants is "core body". From the technical level, diaper core has gone through three revolutions. Diapers are disposable products. It is made of non woven fabric, toilet paper, fluff pulp, high molecular absorbent resin, PE film, rubber band and other materials. There are two kinds of special use for children and adults. The newly developed environment-friendly degradable diapers are made of raw materials extracted from corn fiber, soybean fiber or buckwheat fiber.

Diapers are mainly used by infants and adults. Among them, the Chinese market is mainly baby diapers. Nearly 20 million babies are born in China every year, and more than 40 million babies from 0 to 2 years old use diapers. According to the data of the National Bureau of statistics, in 2008, the population over 60 reached 159.9 million, accounting for 12% of the total population; There are 109.6 million elderly people over 65 years old, accounting for 8.3% of the total population.

Comparison of traditional diapers and diapers:

Many people are influenced by the traditional diaper theory, and think that diapers are better than diapers: ventilation, moisture absorption, not easy to produce diaper rash. To this kind of traditional theory, we should analyze it scientifically and reexamine its correctness.

Of all baby diapers, cotton diapers have the longest history. In modern society, many families still think that cotton diapers are the best choice for nursing newborns. In addition to pure cotton diapers, similar products on the market, such as bamboo fiber diapers, medical fiber diapers, etc.

Because of the frequent replacement of traditional diapers, the amount of cleaning is large, and if you don't pay attention to it, the baby's skin will be easy to soak in urine and toilet stains. The cleaning and drying conditions are not good, and bacteria are easy to breed.

Disposable diapers are popular with young parents. Disposable diapers are easy to carry, no need to clean, easy to replace, but the baby with allergic skin must be replaced frequently, otherwise it is easy to cause the baby red butt and so on.

Bamboo fiber diapers are popular diapers, which are more soft and have good air permeability, natural antibacterial function, not easy to produce odor, easy to clean and so on. They are welcomed by mothers, but they are relatively more expensive than cotton diapers. Compared with diapers, cloth diapers are better for baby's butt, but it's not convenient to carry.

The greatest progress of mankind is reflected in science and technology. Paper intelligent diapers, sanitary mats and so on are all important manifestations of human science and technology. These products not only greatly facilitate people to deal with some things, but also provide more advanced health protection.

Compared with diapers, traditional diapers are better in air permeability, and they are much better, because they only have cloth and no waterproof material. However, it is very unfair to judge the advantages and disadvantages of the two with such comparison results. Because when using traditional diapers, people usually use a waterproof layer on the outer layer of diapers: absolutely airtight plastic paper. So, it's fair to compare the "full version" of traditional diapers with diapers that have no air permeability at all(great) nonwoven diapers are lined with materials that only allow air in and out but not water molecules in and out, so although the air permeability can't be compared with pure cloth, it's much better than "full version" traditional diapers. However, people often ignore the fairness of this contrast, leading to the phenomenon of leaning to the side of traditional diapers.

With the continuous improvement of the production process, diapers have been improved from the original single function of leak proof and urine absorption to both leak proof, breathable, urine absorption and antibacterial, and added a variety of functions, such as stretch elastic waistline, three-dimensional leak proof edge. On the basis of traditional diapers, the new tea diapers have the functions of anti-inflammatory, bacteriostatic and deodorizing.

The core technology of diapers is "core body". From the technical level, diaper core has experienced three revolutions: the first was the birth of disposable diapers half a century ago; the second was the birth of disposable diapers; The second is the application of high polymer absorbent materials in diapers in the 1980s, which fully guaranteed the liquid absorption performance of products. The second generation core is widely used by mainstream brands in the market. However, this kind of traditional core still has some technical limitations in absorption speed, anti reverse osmosis degree, thickness and core strength and toughness, so that the baby's red buttocks, reverse osmosis side leakage and other problems have not been solved.

Diaper manufacturers at home and abroad are stepping up research and development of a lighter, more secure liquid absorption performance, more dry surface diapers, and there are also some semi mature products on the market. It was not until the second half of 2012 that the E-core diaper series was launched, announcing that the third core technology innovation entered the mature application stage. This kind of core has higher absorption efficiency and stronger toughness, which comprehensively solves the major problems of the traditional second generation core. It is commented that the advent of "E-core" technology symbolizes the development of the diaper industry has entered a new era. This is the first time since the invention of diapers in the West that Chinese enterprises have won a leading position in the technology competition of the whole industry.

Can current diapers act as a protective layer?

When experienced mummy chooses diapers again, she is most worried about whether the non protective cloth layer close to the baby's butt can effectively block the stimulation of urine to the baby's butt. It is worth noting that high quality diapers generally add natural skin care ingredients to this layer of non-woven fabric to form a soft protective layer containing moisturizing ingredients.

What is the nonwoven fabric of diapers?

It is not cloth or paper. It is a kind of synthetic chemical fiber rather than plant fiber, but it belongs to textile.

Can the water absorption of diapers give babies high quality sleep?

Research data show that the use of high-quality disposable diapers with strong water absorption capacity and small re infiltration can provide a fully dry environment for the baby's buttock skin, so that the baby will not always feel wet and uncomfortable, thus reducing the times of awakening caused by wet urine, and the sleep time is longer than that of the baby using traditional diapers, which helps the baby sleep more sweetly.
