Diapers are an essential part of infant care, providing convenience and hygiene. A crucial component that makes diapers effective in managing liquid is the super absorbent polymer (SAP). This blog post delves into the role of SAP in diapers, its chemistry, and its impact on performance and sustainability.

## What is Super Absorbent Polymer (SAP)?

Super absorbent polymers are a class of functional polymers known for their ability to absorb and retain large amounts of water and aqueous solutions. They are used in various applications such as medicine, agriculture, and industry, but their most notable use is in disposable baby diapers (DBD).

## Chemistry of SAP

The primary chemical used in SAP is sodium polyacrylate, with the formula (C3H3NaO2)n. This polymer's unique structure, characterized by repeating units, allows extensive cross-linking, which forms the basis for SAP's exceptional absorbency.

## How Does SAP Work in Diapers?

The process of hydration unfolds the magic of SAPs. Hydrophilic groups, such as carboxylate ions within the sodium polyacrylate chains, attract and bind with water molecules through hydrogen bonding. As water infiltrates the polymer network, rapid swelling occurs, transforming the liquid into a gel-like structure. The cross-linked nature ensures the gel retains its form, showcasing SAPs' remarkable water absorption capacity.

## Key Quality Indicators of SAP in Diapers

1. **Absorption Capacity**: High-quality SAPs can efficiently retain a substantial volume of liquid relative to their weight.
2. **Retention Under Load**: Essential for consistent performance in diapers, where pressure is applied.
3. **Particle Size**: Influences dispersion in products, with smaller particles contributing to better distribution and performance.
4. **Rate of Absorption**: Quality SAPs absorb water rapidly, ensuring swift and efficient absorption.
5. **Gel Strength**: Paramount for maintaining the integrity of the absorbent structure, preventing leakage, and ensuring secure moisture retention.
6. **Chemical Purity**: High-quality SAPs are free from impurities, safeguarding their performance and minimizing skin irritation risks.

## Applications in Diapers

1. **Baby Diapers**: SAPs rapidly absorb and lock away urine, providing extended dryness and reducing diaper change frequency, enhancing infant comfort and caregiver convenience.
2. **Adult Diapers**: They contribute to effective moisture absorption, ensuring comfort and dryness for users.
3. **Sanitary Napkins**: SAPs revolutionize menstrual hygiene by efficiently absorbing menstrual fluid, preventing leaks, and providing a sense of security and comfort.

## Environmental Impact and Recycling

The environmental impact of SAPs, especially from disposable diapers, is a concern. An estimated 6.3 billion metric tons of post-consumer polymer waste has been produced, with the majority in landfills or the environment. Recycling methods that utilize these waste polymers could attenuate their environmental impact.

Researchers are exploring ways to recycle SAPs, such as decrosslinking via hydrolysis, chain-shortening via sonication, and functionalizing via Fischer esterification. These recycled materials can be turned into general-purpose adhesives, offering a more sustainable solution.

SAP paper and absorbent paper are two materials that are widely used for their absorbent properties. SAP paper is mainly composed of a combination of materials including tissue paper, super absorbent polymer (SAP) and fluff pulp. Whereas absorbent paper is composed of airlaid paper, SAP and fluff pulp. This article will explore the differences between these two types of paper.



Composition:

SAP paper: SAP paper consists of three parts, including thin tissue paper, SAP and loose cellulose pulp. The thin tissue layer plays a supporting role in the whole structure, and SAP (super absorbent polymer) is the key to achieve high water absorbency. Loose cellulose pulp is used to provide softness and other physical properties.

Absorbent paper: Absorbent paper is made up of three parts, including airlaid paper, SAP and fluff pulp. The airlaid paper layer has a high porosity and air permeability, which helps to improve water absorption, while SAP is responsible for absorbing large amounts of liquid. Fluff pulp is used to enhance structure and provide comfort.



Water absorption performance:

SAP paper has excellent water absorption performance by using super absorbent polymer (SAP). SAP absorbs large amounts of liquid quickly and locks it into the paper structure, keeping it dry. In contrast, absorbent paper has lower water absorption performance, but its loose structure provides a larger water absorption surface area, which is suitable for occasions that need to absorb water for a longer time.



Thickness:

SAP paper is known for its thin and lightweight characteristics. Due to its relatively thinness, SAP paper is often used in thin products such as ultra-thin diapers and thin sanitary napkins. Absorbent paper is relatively thick and is more suitable for products that require larger absorption capacity and extra protection, such as night diapers and extra-large sanitary napkins.



Application areas:

SAP paper is widely used in the production of diapers and sanitary napkins. Its water absorption properties make it an ideal choice for high absorbency and thin appearance requirements. Absorbent paper is also used in some special occasions, usually for products that need to absorb water for a longer time.



Conclusion:

Although SAP paper and absorbent paper are similar in composition, there are significant differences in thickness and use. SAP paper is thinner and suitable for products that require high absorbency and thin appearance, such as ultra-thin diapers and thin sanitary napkins. Absorbent paper, on the other hand, is thicker and is suitable for products that require greater absorption capacity and added protection, such as nighttime diapers and oversized sanitary napkins. For manufacturers, choosing the right material is determined by the specific needs and market positioning of the product.

In modern parenting, diapers are widely used in daily care for babies. In the core technology of diapers, an important ingredient is widely used, which is SAP (Super Absorbent Polymer). This article will introduce in depth the role, properties and application of SAP in diapers. Let us uncover the mystery of SAP in diapers!

What is SAP?
Super absorbent polymer (SAP) is a polymer compound with excellent water absorption performance. It is formed by introducing a cross-linking structure into the polymer chain. The characteristic of SAP is that it can absorb hundreds or even thousands of times its own weight in water and maintain the stability of its structure for a certain period of time.

The role of SAP
SAP plays a key role in diapers. It has the following important functions:
a. Absorbing urine: The main function of SAP is to absorb and fix urine. When urine contacts SAP, it quickly absorbs water and converts it into a gel-like substance, preventing urine from flowing back and effectively preventing leakage.
b. Reducing odor: SAP also helps reduce odor in diapers. It can capture harmful substances such as ammonia in urine, reduce the release of odor, and thus maintain a fresh environment around the baby.
c. Keep dry: SAP in diapers can quickly absorb moisture and lock it in the gel, effectively preventing the baby's skin from contacting urine for a long time, keeping the baby's skin dry, and reducing discomfort and rashes caused by moisture.

Properties of SAP

a. High water absorption: SAP is a material with extremely high water absorption. Due to its cross-linked structure, SAP can quickly absorb a large amount of water and maintain a gel state to prevent water from overflowing.
b. High stability: SAP can maintain the stability of its structure after absorbing water, and will not swell or decompose due to the large amount of water absorbed, thus ensuring the reliability and service life of diapers.
c. Safety: SAP is usually made of non-toxic and non-irritating materials and undergoes strict safety tests. Ensure that it is non-irritating to the baby's skin and meets relevant safety standards.

SAP application in diapers

SAP is widely used in the core part of diapers, usually in the absorbent layer of diapers. It exists in the inner layer of diapers in the form of particles or fluff. When the baby's urine contacts the surface of the diaper, SAP absorbs water and converts it into gel, quickly locking and fixing the urine. This design effectively maintains the baby's comfort and reduces the risk of leakage.

As an important component of diapers, SAP plays a role in comfort, dryness and reliability in the baby's life. Its high water absorption and stability ensure the absorption capacity and performance of diapers. At the same time, the safety of SAP also allows parents to use diapers with confidence and provide a better care experience for their babies. By understanding the role and properties of SAP, we can better understand and appreciate the progress of diaper technology and provide better protection for the growth of babies.

The dual-core body is made of a combination of core structure and wood pulp structure. It is not made of fluff pulp and polymer materials like wood pulp core and composite core. The dual-core body is made of non-woven fabrics, Dust-free paper and water-absorbent polymers are overlapped layer by layer in equal proportions, which effectively improves the water absorption speed of diapers and solves the problem that the wood pulp structure is prone to lumps and fractures.

Under the prefabrication technology, the water-absorbent polymers in the ultra-thin core are evenly distributed, making urine absorption and diffusion faster and more uniform; the reasonable matching ratio of polymers and non-woven fabrics makes the core thinner, more breathable, and more breathable in one fell swoop. It breaks through the defects of the previous two generations of thick cores, poor air permeability, easy faults, and lumps, as well as the relatively weak "absorption" performance of the glue core.

The refined layering technology of the ultra-thin composite core can effectively enhance the absorption capacity of the core. Each layer of polymer plays a role in absorption, conduction speed, absorption speed, diffusivity, and water-locking properties. The ultra-thin composite core has as many as 8 layers, 3 of which are evenly distributed water-absorbing polymers, with the content reaching more than 70%. After the core body absorbs urine, the ultra-high content of water-absorbent polymers can firmly lock in moisture and prevent reverse osmosis, allowing you to stay dry for a long time.

Although the number of layers of the ultra-thin composite core has increased, the core still maintains the characteristics of being light, soft, and breathable. Experimental data shows that the reverse osmosis value of traditional wood pulp cores is generally above 3g, while the reverse osmosis value of the fourth generation multi-layer core is less than 1g. At the same time, the core uses zoning technology, and the surface uses S-shaped breathable grooves, which reduces the contact between the skin and the diaper surface, leaving 2 breathable channels, which further improves the breathability of the core on the basis of being "light and thin" , light and not stuffy.
