Types of Polyester Non Woven Fabrics

Polyester non woven fabrics come in various types, each with unique manufacturing techniques and properties. The most common types include meltblown and needle-punched fabrics.

Meltblown nonwoven fabrics are produced by extruding polymers, which are then formed into fibers that are cooled and bonded into a cloth. This type of fabric is known for its fine filtration properties, making it ideal for applications that require high efficiency in filtering particles.

On the other hand, needle-punched fabrics are created using needles to interlock and reinforce a fibrous web. This method produces a fabric that is robust and durable, suitable for applications that demand high tensile strength and resilience.

In summary, the primary types of polyester non woven fabrics include meltblown and needle-punched fabrics, each serving distinct purposes in various industries.

Production Techniques

The production of polyester non-woven fabrics involves various techniques, each tailored to achieve specific properties and applications. One common method is heat-sealing, where a bonding material within the fabric is melted and then consolidated to form a stable fabric.

Mechanical bonding is another technique, which uses physical forces to entangle fibers and create a fabric without the use of adhesives. This method makes it often used to produce fabrics that are durable and can withstand significant wear and tear.

Spunlace nonwoven fabrics are produced using high-pressure water jets to entangle fibers together, creating a fabric that is soft and absorbent. This technique is particularly useful for hygiene and medical products where comfort and moisture management are crucial.

Stitchbond fabrics involve a stitching process that combines fiber webs and nonwoven materials to enhance reinforcement and durability. Furthermore, polyester non-woven fabrics can undergo additional processing to incorporate specific properties such as UV resistance or antistatic features, making them even more versatile for various applications.

Key Characteristics

Polyester non woven fabrics are renowned for their high tensile strength and good abrasion resistance, which make them exceptionally durable under stress. These fabrics can withstand significant wear and tear, making them suitable for demanding applications.

The weight and thickness of polyester non woven fabrics can vary widely, with weights ranging from 6.4 to 81.1 oz/yd² and thicknesses from 0.03 inches to 0.09 inches. This variability allows for customization based on the specific needs of different applications, whether light and flexible or thick and robust.

Chemical bonding is a technique that relies on adhesives to bind fibers together, enhancing the fabric’s durability. Ultrasonic bonding, on the other hand, uses high-frequency sound waves to create precise and localized connections between fibers, resulting in a strong and stable fabric structure. Through-air bonding employs hot air to thermally fuse fibers, producing a soft and open fabric structure.

Polyester non woven textiles can also be engineered to exhibit specific performance characteristics such as breathability and moisture-wicking, making them ideal for applications that are required for comfort and moisture management. For example, these textiles are widely used in activewear and outdoor gear.

Applications in Various Industries

Polyester non woven fabrics are extensively used across various industries due to their versatile properties and adaptability. They find applications in the medical field, construction, and the textile industry, among others.
