The ultra-thin absorbent core is the key structure of disposable diapers, enabling ultra-light wearing experience and efficient fluid absorption. Primarily composed of air-laid paper (absorbent bulk paper) and Super Absorbent Polymer (SAP), it has become the prevailing technical solution in the industry. Air-laid paper features fluffy structure and excellent toughness with outstanding liquid spreading performance. It evenly distributes bodily fluid, fully encapsulates and immobilizes SAP particles to prevent powder migration and dust leakage. It also maintains the structural integrity of the core and effectively eliminates clumping and layer separation after fluid absorption. Its inherent fibrous pores facilitate moisture dissipation and further improve air permeability. Serving as the SAP core absorbent and retention medium, SAP delivers ultra-high absorption capacity and superior fluid locking performance. It quickly entraps large volumes of urine and effectively inhibits rewetting. Adopted with layered lamination and precision powder deposition technologies, the composite structure achieves significant thickness reduction without compromising absorption efficiency. Furthermore, functional nonwoven fabrics are applied as auxiliary layers on both sides of the core. The top nonwoven fabric accelerates fluid distribution and air exchange, while the bottom breathable PE film provides reliable leak-proof protection. The synergistic combination of diverse materials produces high-performance ultra-thin cores that excel in lightness, softness, absorption and air permeability.

In recent times, the escalating geopolitical conflicts and volatile situation in the Middle East have triggered ripple effects across the global diaper and diaper raw materials industries. These impacts have permeated critical areas—including raw material costs, logistics and transportation, and foreign trade orders—posing severe challenges for foreign trade suppliers of diaper raw materials as well as downstream enterprises.   On the cost front, crude oil prices have remained volatile at elevated levels. Consequently, prices for core diaper raw materials—specifically Polypropylene (PP) and Polyethylene (PE)—have continued their upward trajectory. Specialized diaper components—such as spunbond non-woven fabrics, PE films, and elastic waistband materials—have seen actual price increases ranging from 8% to 18%. Concurrently, instability in raw material supplies has caused periodic delivery delays at certain upstream factories, further intensifying the strain on the diaper raw material supply chain. Regarding logistics, transit conditions along the Persian Gulf and Red Sea routes have been erratic; the Strait of Hormuz has repeatedly closed and briefly reopened. Vessels have been compelled to reroute around the Cape of Good Hope or divert to alternative ports in the Middle East, resulting in a 40% increase in voyage distance. Shipping schedules have faced delays of one to three months, and some cargo shipments have even been forced to turn back mid-voyage or have been "rolled over" (left behind) at ports. Furthermore, war risk insurance premiums have skyrocketed, and both sea freight rates and surcharges have climbed sharply, significantly driving up foreign trade costs. From a market perspective, export orders to the Middle East have become polarized. Demand for basic-tier diapers—considered essential necessities—has stabilized, leading to relatively steady demand for corresponding basic-grade raw materials. However, demand for high-end diaper categories has been slashed by half, resulting in a parallel decline in orders for premium raw materials. Simultaneously, payment collection risks have surged; instances of Middle Eastern clients losing contact, coupled with the depreciation of local currencies, have caused the risk of bad debts regarding final payments to skyrocket.   In the long term, the de-risking of petrochemical supply chains for diaper raw materials and the diversification of foreign trade export markets are emerging as key trends. Regions far removed from conflict zones—such as Latin America and Africa—are becoming the new focal points for strategic foreign trade expansion in the diaper raw materials sector. As a supplier of diaper raw materials, we are actively optimizing our supply chain and enhancing our resilience to effectively navigate these uncertainties.

The topsheet and diversion layer are key to sanitary products’ comfort and performance. The top layer directly contacts skin, quickly conducting fluids inward without absorbing them, requiring high permeability to keep skin dry. The ADL diversion nonwoven layer lies between the top layer and absorbent core, accelerating liquid diffusion, guiding fluid into the core, and reducing rewet for better dryness. Most hygiene products use soft hot-air nonwovens for these layers, made from ES bicomponent fibers (PP/PE, PET/PE) via carding and thermal bonding. ES fibers have core-sheath or symmetric structures; thermal bonding melts low-melting components to form point bonds, creating a stable 3D structure with high resilience, softness, and excellent liquid transport. This material absorbs over 10 times its weight in liquid. Thermal-bonded nonwovens are now widely used in high-end sanitary napkins and diapers.

Diaper polymer, or Super Absorbent Polymer (SAP), is the core component of modern disposable diapers. Its exceptional water absorption and retention capabilities have revolutionized the user experience of care products. Typically appearing as white particles, it is a water-swellable polymer with a three-dimensional network structure, synthesized from raw materials such as starch and acrylates through polymerization. Its key advantage lies in its remarkable water absorption capacity—able to absorb hundreds of times its own weight in water. Upon contact with urine, it swells rapidly to form a stable hydrogel, which firmly locks in moisture through osmotic pressure, hydrogen bonding, and other mechanisms, resisting rewetting even under external pressure. This feature keeps diapers dry for extended periods, minimizes skin contact with urine, and effectively reduces the risk of diaper rash. As a key component of the diaper’s absorption layer, it works in synergy with fluff pulp: fluff pulp aids in urine diffusion, while the polymer is responsible for efficient water locking. Their combination ensures rapid absorption while enhancing user comfort. High-quality diaper polymers undergo rigorous safety testing, being non-toxic, harmless, and skin-friendly, making them suitable for infants, young children, and adults alike. Today, they have become an indispensable core material for disposable hygiene products, driving the development of care products toward being thinner, more efficient, and more comfortable.

With rising living standards, consumers are paying more attention to product value and experience rather than just price. Diapers, as an everyday necessity, rely on the quality of their core materials: super absorbent polymer (SAP), non-woven fabric, and breathable film. Many mothers may have seen these names on the packaging but are unaware of their specific functions. Below, we briefly explain the functions of these three materials. Super absorbent Polymer (SAP) SAP has high water absorption and retention capabilities, absorbing dozens of times its own weight in water. It can form a gel within seconds, and the gel volume can expand dozens of times, locking in liquid and preventing leakage, keeping the inside of the diaper dry. Non-woven Fabric Mainly used in the topsheet of diapers, it directly contacts the baby's skin. The most commonly used types are airthrough non-woven fabric and spunbond non-woven fabric, with airthrough non-woven fabric offering better performance. It is breathable, waterproof, soft, lightweight, non-toxic, and non-irritating, reducing skin irritation and helping to quickly transfer liquid to the inner absorbent material. Breathable PE Film Usually located on the backsheet of the diaper, it has water-repellent and breathable functions. Polyolefin breathable film is made by adding inert fillers to a PE or PP carrier, followed by film formation and stretching. During the film formation process, high-ratio stretching creates pores, giving it breathability and moisture-wicking properties. Its microporous structure prevents liquid leakage while allowing moisture to escape, helping to maintain skin comfort and reduce stuffiness. These three materials work together to ensure the performance of the diaper in terms of absorption, contact comfort, and breathability and leak prevention, meeting consumers' demands for product quality and user experience.
