Spunlace nonwovens are high-end flexible materials formed by utilizing high-pressure, fine water jets to entangle fibers. As a high-performance substrate, they require no chemical binders and possess a unique combination of attributes—including softness, skin-friendliness, breathability, comfort, exceptional strength, and low linting—making them widely applicable across numerous core sectors such as hygiene and personal care, healthcare, industrial wiping, and synthetic leather production.

In the realm of personal care, spunlace nonwoven fabric serves as a primary raw material for disposable hygiene products such as wet wipes, facial cleansing cloths, and flushable toilet wipes. Utilizing premium raw materials like fluff pulp and viscose, it demonstrates superior liquid and oil absorption capabilities while exhibiting minimal linting and shedding; furthermore, it offers excellent versatility for both wet and dry applications. Whether in the form of baby wipes designed to gently care for delicate skin, or eco-friendly flushable toilet wipes that are biodegradable and easily dispersible, these products effectively meet the public's daily hygiene and care requirements, offering both convenience and safety.

In medical and healthcare settings, spunlace fabric is truly indispensable. Characterized by an absence of chemical residues, excellent biocompatibility, and high levels of cleanliness, it is utilized in products such as medical gauze, surgical towels, and disposable protective supplies. It effectively blocks contaminants, absorbs wound exudates, and minimizes irritation to both the skin and the wound site, thereby balancing both safety and practicality. 

Bolstered by these multiple core advantages, spunlace nonwoven fabric continues to drive the evolution of hygiene products toward higher standards of safety and premium quality.

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.

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.
