Comparison And Analysis of Diaper Materials

Diapers are essential products for every baby family. Their comfort, safety and environmental friendliness have a direct impact on the baby's health and the parent's experience. This article will explore the different materials used in diapers and help parents make wise choices through comparative analysis.

Structure of diapers

Before analyzing the material of diapers, first understand its basic structure. Diapers are usually composed of three main layers:

Top Sheet

The top sheet is in direct contact with the baby's skin. Its material needs to be soft, breathable and have good moisture absorption to keep the baby's skin dry.

Absorbent Core

The absorbent core is the core of the diaper, responsible for quickly absorbing and locking urine to prevent leakage. Its main materials include super absorbent resin (SAP) and fluff pulp.

Back Sheet

The back sheet is the outer waterproof layer of the diaper, which prevents urine from leaking to external clothing. It is usually made of polyethylene (PE) film or non-woven fabric.

Comparative analysis of top sheet materials

Top sheet materials are in direct contact with the baby's skin, so the choice of materials is crucial. Common top sheet materials are:

Non-woven fabrics

Non-woven fabrics are the most common top sheet materials and are widely used because of their softness and breathability. The main component of non-woven fabrics is polypropylene (PP), which is not easy to cause allergies and has good hygroscopicity.

Advantages:

- Soft and breathable, not easy to cause skin allergies.

- Good hygroscopicity, keep the skin dry.

Disadvantages:

- Although the breathability is good, it is still not as good as natural fibers.

- Chemical additives may be used in the manufacturing process, affecting environmental protection.

Pure cotton fiber

Pure cotton fiber top sheet material is softer and more breathable, suitable for babies with sensitive skin.

Advantages:

- Natural softness and excellent breathability.

- No chemical additives, natural and environmentally friendly.

Disadvantages:

- High cost and relatively expensive.

- Hygroscopicity is not as good as non-woven fabrics, and needs to be replaced more frequently.

Bamboo fiber

Bamboo fiber is an emerging environmentally friendly material with natural antibacterial and mildew-proof properties.

Advantages:

- Natural antibacterial, mildew-proof and deodorizing.

- Environmentally friendly and degradable, friendly to the environment.

Disadvantages:

- Higher price.

- Slightly inferior to pure cotton fiber in softness and comfort.

Comparative analysis of absorbent layer materials

The absorbent layer is the core of diapers and determines the water absorption and water-locking capacity of diapers. The main materials include:

Super absorbent polymer (SAP)

SAP is a material with extremely strong water absorption capacity, usually used in combination with fluff pulp. It can quickly absorb a large amount of urine and firmly lock in moisture.

Advantages:

- Strong water absorption capacity, can keep dry for a long time.

- Excellent water-locking performance, prevent urine back-seepage.

Disadvantages:

- The main component is chemical substances, which have a certain impact on the environment.

- Once too much water is absorbed, it may clump and affect comfort.

Fluff pulp

Fluff pulp is a natural absorbent material made from wood pulp, usually used in combination with SAP to enhance the absorption effect.

Advantages:

- Natural material, relatively environmentally friendly.

- It still maintains a certain softness after absorbing water.

Disadvantages:

- The water absorption capacity is not as good as SAP when used alone.

- The absorption speed is slow and needs to be used with SAP.

Composite materials (absorbent core)

Some high-end diaper brands use composite materials (absorbent core), combining multiple absorbent materials to achieve the best effect.

Advantages:

- Fast water absorption and strong water lock ability.

- More scientific material design, enhancing baby's comfort.

Disadvantages:

- Complex production process and high price.

- Complex material composition may affect environmental protection.

Comparative analysis of back sheet materials

The back sheet material is mainly responsible for waterproofing, and common materials include:

Polyethylene (PE) film

PE film is the most common back sheet material with excellent waterproof performance.

Advantages:

- Excellent waterproof performance, preventing urine leakage.

- Low cost and wide use.

Disadvantages:

- Poor air permeability, which may cause the baby's skin to be stuffy.

- Non-degradable, has a certain impact on the environment.

Non-woven fabrics

Non-woven fabrics are also used as back sheet materials, usually non-woven fabrics with good air permeability are used in combination with PE film.

Advantages:

- Good air permeability, reducing the feeling of stuffiness on the skin.

- High softness, increased comfort.

Disadvantages:

- Waterproof performance is not as good as pure PE film.

- High cost.

Degradable materials

With the improvement of environmental awareness, some brands have begun to use degradable materials like PLA non-woven as the base layer to reduce the environmental burden.

Advantages:

- Environmentally friendly and degradable, reducing pollution.

- Usually has good breathability and improves comfort.

Disadvantages:

- High cost and low market coverage.

- Waterproof performance needs to be further improved.

Brand case analysis of diapers of different materials

1. Mainstream brands. Like Pampers, Kao usually use non-woven top sheet, SAP and fluff pulp composite absorption layer and PE film back sheet to achieve a good balance of water absorption, leakage prevention and comfort.

2. Environmentally friendly brands.Like Bambo Nature, Naty are committed to using natural fibers and degradable materials to reduce the impact on the environment. This type of diapers is more expensive, but it performs well in comfort and environmental protection.

3. High-end brands. Merries and Libel use advanced composite materials and processes to provide excellent water absorption and comfort, suitable for families with high quality requirements.

Recommendations for choosing diapers suitable for babies

• Choose according to baby's skin type. For babies with sensitive skin, it is recommended to choose diapers with pure cotton fiber or bamboo fiber surface to reduce the risk of allergies.

• Choose according to the use scenario. For nighttime use, it is recommended to choose highly absorbent resin diapers with strong absorption capacity, while non-woven diapers with good breathability can be chosen during the day.

• Pay attention to environmental awareness. Parents with environmental awareness can choose diapers made of degradable materials to reduce the impact on the environment.

• Brand reputation and user reviews. When choosing a brand, you can refer to the reviews and reputation of other users and choose a brand with good reputation and guaranteed quality.

Conclusion

The choice of diaper material is directly related to the comfort and health of the baby, as well as environmental issues. Through in-depth understanding and comparative analysis of different materials, parents can choose the most suitable diapers according to their baby's specific needs and family situation. Regardless of the material chosen, it is of utmost importance to ensure that the diapers are safe, comfortable and environmentally friendly. If you need raw materials for diapers, contact us.
