Wet Laid Nonwoven Fabric

Product Description

Wet-laid nonwoven fabric stands out for its fine fiber distribution, smooth surface, and consistent weight. It provides a paper-like texture with superior uniformity compared to dry-laid or spunlace fabrics. These features make it suitable for technical and industrial applications requiring high stability and clean processing performance.

In garment manufacturing, it can also be used as embroidery stabilizer backing, offering clean tearability and smooth embroidery support without stretching or distortion.

Key Features

• Excellent Uniformity: Even fiber dispersion ensures consistent structure and a smooth surface.

• High Dimensional Stability: Maintains shape and strength during processing and use.

• Soft and Paper-like Texture: Ideal for coating, lamination, or printing applications.

• Chemical and Thermal Resistance: Suitable for both wet and dry environments.

• Customizable Weight and Composition: Adjustable fiber blend to meet specific application needs.

• Biodegradable Options Available: Cellulose or viscose-based wet-laid fabrics support sustainable development.

 

Product Advantages of Wet Laid Nonwoven Fabric

Wet-laid nonwoven fabric is manufactured using a process similar to traditional papermaking, where fibers are dispersed in water and then uniformly deposited onto a forming screen. This method allows for exceptional fiber distribution control, resulting in a fabric with high uniformity, smooth surface quality, and precise thickness control.

Compared with other nonwoven technologies, wet laid production enables the use of very fine fibers and specialty fibers, including cellulose, synthetic fibers, glass fibers, and functional blends. The result is a nonwoven fabric with excellent consistency, low linting, and high dimensional stability, even at low basis weights.

Because of its controlled structure and clean processing characteristics, wet-laid nonwoven fabric is especially valued in applications where surface quality, precision performance, and material purity are critical.

 

Production Process

1. Fiber Dispersion: Short fibers (cellulose, viscose, polyester, glass fiber, etc.) are dispersed evenly in water to form a slurry.

2. Web Formation: The slurry is deposited onto a moving screen to create a uniform fiber web.

3. Bonding: The web is strengthened through chemical, mechanical, or thermal bonding, ensuring stability and strength.

4. Drying & Finishing: The bonded fabric is dried, calendered, and rolled to achieve the desired thickness and surface finish.

This advanced process produces a thin, even, and durable nonwoven fabric suitable for various industrial and textile uses.

Wet Laid Nonwoven Fabric vs. Dry-Laid & Spunlace—Application-Oriented Perspective

Wet-laid nonwoven fabric is not designed to replace spunlace or dry-laid nonwovens in general-purpose applications. Its strength lies in precision and uniformity, rather than bulk softness or high tensile strength.

Wet-laid nonwoven fabric is typically selected when:

Extremely uniform fiber distribution is required

Very low basis weight fabrics must maintain stability

Low linting and clean surface are essential

Functional fibers need to be evenly dispersed

Spunlace fabrics are often preferred for their soft, textile-like hand feel, while dry-laid nonwovens may focus more on thickness and mechanical strength. Wet laid technology fills a unique position where material control and consistency matter more than fabric bulk.

 

Functional Treatments & Structural Customization Options

Wet-laid nonwoven fabric offers extensive customization possibilities at both the fiber and finishing levels:

• Fiber composition customization (cellulose, synthetic, blended fibers)
• Hydrophilic or hydrophobic treatment
• Resin bonding or chemical bonding options
• Low-lint and dust-free finishing
• Controlled pore size and permeability
• Antibacterial or functional additives
• Custom basis weight, thickness, and roll format

Weboss works closely with customers to fine-tune wet-laid structures to meet strict application and processing requirements, especially in technical and industrial uses.

 

Common Applications of Wet Laid Nonwoven Fabric

Due to its precision structure and surface uniformity, wet laid nonwoven fabric is widely used in:

• Industrial and laboratory wipes
• Medical and healthcare disposables
• Filtration media (air and liquid filtration)
• Battery separators and technical insulation
• Electronics and cleanroom applications
• Embroidery stabilizer backing and specialty backings
• Composite nonwoven layers requiring uniform structure

Its ability to deliver consistent performance at low basis weights makes wet-laid fabric ideal for high-specification environments.
