What are the baby diapers structures?

The current nappy structure is generally a four-layer structure. (Functional layer + materials used)

1、Surface layer Non-woven fabric

2、Conductive layer Specialised non-woven fabric

3、Absorbent layer Toilet paper + fluff pulp + SAP

4、Bottom layer PE film or PE film + non-woven fabrics

In addition, it is supplemented with adhesive fixing structure and three-dimensional anti-leakage structure.

The surface layer is in direct contact with the baby's skin, accepts the liquid and passes it on. The surface layer has high requirements for the material, which is soft to the touch and does not irritate the baby's skin.

The conductive layer is the most important item in a thin or ultra-thin nappy. The conductive layer transfers the liquid received by the surface layer to the absorbent layer, which is required to provide a large enough space to store and transfer a sufficient amount of liquid as quickly as possible.

The absorbent layer, is the most important functional layer in a nappy.

The function of the bottom layer is to prevent leakage, and the composite bottom layer that is commonly used nowadays is what gives the nappy a more cloth-like feel and a better hand feel.

What are the materials used in baby diapers?

First, the general raw materials of the general baby diapers

Non-woven fabric, infusion layer, tissue paper, SAP, bottom film, rubber bands, adhesive stickers (front + left and right), waistband elastic, etc..

Second, the evolution of some of the materials used

1. Nonwoven fabrics: the functional classification of nonwoven fabrics used in baby diapers is becoming increasingly refined. Surface hydrophilic non-woven fabrics, water-resistant non-woven fabrics, penetration layer non-woven fabrics.

2. Adhesive: plastic adhesive tape (ordinary - mute) - non-woven adhesive tape - Velcro

3. SAP: the proportion of SAP in the core body is a growing trend, initially below 10%, and now the general situation is about 30%-40%, individual up to 70%.

4. Base film: PE film or PE film + non-woven fabrics

5. PE film: ordinary film - breathable film - breathable composite film

Dealers and consumers care about the selling point of baby diapers

First, the brand benefits

Second, quality assurance (ultra-thin cotton soft)

1. Ultra-thin absorption core

2. Cubic anti-leakage partition

3. Cute cartoon re-posting area

4. Thoughtful breathable bottom layer

5. Wonderful "wet show" function

6. Elasticated fit

Baby diapers development trends

1, Thin --- baby diapers will continue the development of the trend of thin shape, which is the mother's requirements is also the manufacturer to compress the cost of the results. Loose and thick baby diapers bring a lot of inconvenience to mothers and babies. In terms of producers, loose thick baby diapers undoubtedly occupy a larger space, consume more costs in terms of supplies and transport, manufacturers will gradually increase the content of SAP, reduce the proportion of fluff pulp to cope with consumers to improve the demand for baby diapers absorbent, objectively also make the diapers towards the development of thin direction.

2, Skin care - baby diapers provide mothers and babies convenient at the same time, but also hidden disadvantages, nappy rash is one of the unavoidable problems, there are individual differences in factors, but as high as 35% of the rate of suffering (Nonwovens World, February-March 2000) to the forefront of this issue. The use of baby diapers is not just a figure of convenience, it is total pampering. Skin care is the mother's desire, but also market-oriented.

3, Environmental protection - the surface of the nappy is not easy to decompose can be said to be a kind of "white pollution", environmentalists also attacked this point to resist. With the advancement of society, the importance of environmental protection is becoming increasingly prominent and attention, the production of environmentally friendly baby diapers rather than a product of pressure, rather than a necessity.

4, Synthetic core - the core is the most important functional layer of baby diapers, the production process is complex, and polymer and fluff pulp mixing conditions directly affect the performance of the product. The future of the core towards the development of synthetic type, it is composed of idealised dust-free paper, containing a uniform mix of SAP and fluff pulp, in the liquid control performance to enhance better characteristics and performance. Core processing from the entire production process out of the division of labour, the production of baby diapers only need to choose the functional layer of synthesis can be, not only to simplify the production process, to ensure the integrity and softness of the diaper, but also effective cost control.

5, Training pants / pull-ups - training pants first appeared in Europe and the United States in the 1990s. Waist and leg circumference of the large area of the material is non-woven fabric and rubber band, not only excellent elasticity, more comfortable fit, and does not bring a lot of production costs. In Japan, the price of training trousers is not far from that of adhesive baby diapers. In China, mothers give children very early to put shit and urine, and posture against nature, often causing children to cry and scream, leading to psychological hazards, let children wear training trousers is to cultivate children's toilet habits of an effective way to take advantage of the children's willingness to grow into a big kid and love to imitate the psychology of the child to wear self-service baby diapers - training trousers, not only to ensure the safety, but also to maintain the child's training habits, not only the safety, but also to maintain the child's training trousers. It's a safe way to keep your child's self-esteem, and it's good for your child's physical and mental health.

6, Elastic fit ---- rigid and tight baby diapers are not conducive to Baby's movement. More elastic materials have been developed and designed to make the nappy elastic and snug, so that the baby is more comfortable in doing crawling, walking and other sports. These elastic materials and designs include elasticated waistbands, elasticated big ear patches, and so on.

 7, Soft ---- thin design can play to make the nappy soft effect, but in order to further improve the comfort of the baby's skin, the choice of ultra-soft surface fabric is a must, but also need to screen the softness of other materials, including absorbent paper, backing film, as well as hot melt adhesive.
