Introduction


Adult diapers have become an essential product for individuals dealing with incontinence, mobility issues, or age-related health challenges. As the global population ages and chronic conditions like diabetes and dementia become more prevalent, the demand for adult diapers continues to rise. A critical factor in the quality and performance of adult diapers lies in their raw materials. This article explores the various types of raw materials used in adult diaper production, their functions, market trends, and how these materials contribute to the overall effectiveness and user satisfaction of adult diapers.





1. Raw Materials for Adult Diapers


1.1 Top Layer Materials


The top layer materials are of paramount importance, as they are the primary interface with the user's skin. Typically, this layer is composed of breathable non-woven fabric, ensuring optimal comfort and skin health. This material is selected for its softness and capacity to facilitate air circulation, which contributes to the prevention of skin irritation and the development of rashes. The top layer's comfort and gentle texture are paramount to user satisfaction, particularly for individuals who may require adult diaper use for extended periods.


1.1.1 Hot Air Through Non-woven

The material's breathability facilitates hot air diffusion through the non-woven structure. This material is particularly well-suited for high-end adult diapers due to its fluffy texture. However, it is important to note that this material is more expensive than spunbond nonwovens.

1.1.3 PLA Non-woven

This new type of biodegradable nonwoven fabric is considered to be the trend surface layer of the future due to its environmental friendliness.




1.2 Absorbent Core Materials



The absorbent core is the pivotal component of adult diapers, responsible for capturing and retaining liquid. This layer is composed primarily of cellulose fibers, which impart superior absorbency and diffusion properties. In addition to cellulose fibers, super absorbent polymers (SAP) are incorporated into the core. These polymers, which are synthetic in nature, possess the remarkable capacity to absorb and retain liquid amounts that often reach up to 30 times their own weight. This amalgamation of cellulose and SAP guarantees that the diaper remains dry and comfortable for extended periods.

1.2.1 Tissue Paper

The application of polymer coating on two distinct layers, designated as the upper and lower layers, respectively, is a critical aspect of the diaper's design.


1.2.2 SAP (Super Absorbent Polymer)

The primary absorbent material in this category includes brands such as San- dia and Sumitomo, among others.


1.2.3 Airlaid paper

Some manufacturers may opt to utilize airlaid paper in lieu of toilet paper for the purpose of wrapping SAP.

1.3 Bottom Layer Materials


The bottom layer functions as a barrier to prevent leakage while still allowing some degree of breathability. Common materials used in this application include polypropylene and polyethylene films, which are waterproof yet designed to allow minimal air exchange. Achieving the optimal balance between preventing leakage and maintaining breathability is crucial to avoid skin irritation and ensure user comfort.


1.3.1 PE film

It is the most popular product as a backsheet of diapers, and some of them are breathable. The effectiveness of this material depends on its position within the product.

1.3.2 Spunbond Nonwoven

Some manufacturers may use it as a backsheet for adult diapers.




1.4 Elastic Materials


Elastic materials are used in the waistband and leg cuffs to ensure a snug, secure fit. These materials, often elastic non-woven fabrics or spandex yarn, help prevent leaks by creating a tight seal around the legs and waist. The elasticity also allows for flexibility, ensuring that the diaper remains comfortable even during movement.

1.5 Hot Melt Adhesive


Hot melt adhesive is a plasticity adhesive that, within a certain temperature range, undergoes changes in its physical state with temperature, while maintaining constant chemical properties. It is non-toxic and tasteless, and is an environmentally friendly chemical product. It is the primary material used in the assembly of adult diaper structures.



1.6 Closure System


Adhesive Closure System: Which are the best products for reliable and economical needs. They stick firmly to PE backsheet, and you can make products in different colors, shapes, and sizes. The main products are 2 or 3-ply PP tapes.

1.7 Other Materials


Z tape: A tape for easy recycling and disposal of adult diapers.

Packaging bag: Mainly PP bags, support pattern customization.

ADL: It effectively facilitates the rapid conduction of the liquid inward from the surface layer of the covering material and allows the liquid to spread and distribute vertically, thus allowing the liquid to quickly leave the user's skin and enter the SAP absorbent core.

2. Performance and Functionality of Adult Diaper Raw Materials


2.1 Absorbency and Liquid Retention


The primary function of adult diaper raw materials is to absorb and retain liquids effectively. The absorbent core, with its cellulose and SAP components, works to draw liquid away from the skin and lock it in place. This not only keeps the user dry but also reduces the risk of skin irritation and infections.



2.2 Breathability


Breathability is another critical factor, as it helps regulate moisture and temperature against the skin. Materials like breathable non-woven fabrics in the top and bottom layers allow air to circulate, preventing the buildup of moisture and heat, which can lead to discomfort and skin problems.


2.3 Softness and Comfort


The tactile experience of wearing an adult diaper is vital for user satisfaction. Soft, non-irritating materials in the top layer ensure that the diaper is comfortable for extended use, especially for individuals with sensitive skin.


2.4 Odor Control


Many modern adult diapers incorporate odor-neutralizing agents in their raw materials. These agents work to neutralize ammonia odors, which can be a significant concern for users and caregivers. Materials like activated carbon or specially treated SAPs are often used for this purpose.
