What Are Airlaid Nonwovens?
Airlaid nonwovens are high‑performance, absorbent materials engineered to deliver bulk, softness, strength, and uniformity in applications where liquid management and comfort matter most. Manufactured using air rather than water to form the fiber web, airlaid materials offer a unique balance between paper‑like absorbency and textile‑like performance. Airlaid nonwovens technology is valued for its design flexibility and consistent performance, making it a reliable solution across hygiene, wipes, medical, food packaging, and industrial markets.
How Airlaid Nonwovens Are Manufactured
The random orientation of fibers in airlaid nonwovens results in uniform strength and performance in every direction, making them well suited for absorbent product applications. Airlaid nonwovens are often described as bridging the gap between paper and fabric, combining the absorbency of paper with the softness, thickness, and integrity of a nonwoven fabric.
The airlaid nonwovens process allows for precise control over material properties. While formulations can vary by application, the core manufacturing steps include fiber preparation, air web formation, bonding methods, and finishing and converting.
Step 1: Fiber Preparation
Airlaid nonwovens are produced primarily from cellulose fibers, most commonly wood pulp, that are individualized and formed into a web using air. Cellulose pulp sheets are mechanically defibered into individual fibers. Depending on performance requirements, the fiber blend may include:
- Synthetic or bicomponent fibers
- Superabsorbent polymers (SAP)
- Functional additives
Step 2: Air Web Formation
After preparation, the fibers are suspended in an air stream and deposited onto a moving forming wire. Unlike traditional paper or wetlaid nonwovens, the airlaid process does not rely on water to disperse fibers. Since no water is used, the web maintains loft, porosity, and isotropic strength, which are difficult to achieve with other nonwoven technologies. This results in a bulkier, more open structure with excellent absorbency and softness.
Step 3: Bonding Methods
To provide strength and durability, the airlaid web is bonded using one or more of the following techniques:
- Adhesive / latex bonding for flexibility and absorbency
- Thermal bonding for strength and cleanliness
- Hydrogen bonding for natural fiber integrity, softness, and absorbency
- Hybrid or multi‑bond systems for optimized performance
The bonding approach directly influences absorbency, softness, tensile strength, and end‑use durability.
Step 4: Finishing and Converting
Following bonding, airlaid materials are finished and converted to meet exact customer and application requirements. This includes precision slitting, embossing, laminating, and custom roll preparation to ensure consistent performance and efficient downstream processing.
Embossing can enhance bulk, softness, and fluid management, while lamination enables the integration of additional functional layers such as films or other nonwovens. Materials are supplied in roll formats engineered to customer specifications for seamless integration into a variety of end-use applications.
This final step ensures each airlaid product delivers the right balance of performance, consistency, and processability, engineered to meet both functional demands and production efficiencies.
Key Performance Characteristics of Airlaid Nonwovens
Airlaid nonwovens are selected when performance requirements exceed what traditional papers or lightweight nonwovens can deliver. Key performance characteristics include:
- High Liquid Absorbency and Retention
The open structure efficiently absorbs, distributes, and retains fluids.
- Softness and Cushioning
Airlaid nonwovens provide a comfortable, cloth‑like feel with added bulk.
- Uniformity and Consistency
Even fiber distribution ensures predictable performance across the entire web.
- Wet and Dry Strength
Proper bonding maintains integrity in demanding conditions.
- Design Flexibility
Fiber blends, basis weights, and bonding systems can be tailored to specific applications.
