Abrasion resistance is a crucial property when it comes to non - woven fabrics, especially those produced by spunbond non - woven machines. As a supplier of Spunbond Non - Woven Machines, I have witnessed firsthand the importance of understanding these properties for both manufacturers and end - users. In this blog, we will delve into the abrasion resistance properties of non - woven fabric made by spunbond non - woven machines.
Understanding Spunbond Non - Woven Fabric Production
Before discussing the abrasion resistance, it's essential to understand how spunbond non - woven fabric is produced. The process starts with polymer chips being melted and extruded through spinnerets to form continuous filaments. These filaments are then drawn and laid randomly on a conveyor belt to form a web. The web is then bonded together through various methods such as thermal bonding, chemical bonding, or mechanical bonding. This unique production process gives spunbond non - woven fabric its distinct characteristics.
The production process is well - explained in the Producing Non - Woven Fabric webpage, which provides in - depth knowledge about the steps involved in creating high - quality non - woven fabrics.
Factors Affecting Abrasion Resistance
Polymer Type
The type of polymer used in the production of spunbond non - woven fabric significantly impacts its abrasion resistance. Polypropylene is one of the most commonly used polymers in spunbond non - woven production. It has good abrasion resistance due to its high crystallinity and relatively low friction coefficient. Polyester is another polymer that can be used. Polyester - based spunbond non - woven fabrics often exhibit excellent abrasion resistance, especially when compared to other polymers. The chemical structure of the polymer determines its ability to withstand the forces exerted during abrasion.
Fiber Fineness
Fiber fineness plays a vital role in abrasion resistance. Finer fibers generally have a larger surface area per unit mass, which can lead to better bonding between fibers. This results in a more cohesive and stronger fabric structure, enhancing its abrasion resistance. However, if the fibers are too fine, they may be more prone to breakage under high - stress abrasion conditions. On the other hand, coarser fibers can provide more mechanical strength against abrasion in some cases, but they may also result in a less smooth and potentially less aesthetically pleasing fabric.
Bonding Method
The bonding method used to hold the fibers together in the non - woven web is critical for abrasion resistance. Thermal bonding is a popular method where the fibers are heated to a point where they partially melt and fuse together. This creates strong bonds between the fibers, improving the fabric's ability to resist abrasion. Chemical bonding involves the use of adhesives to bond the fibers. The type and amount of adhesive used can affect the abrasion resistance of the fabric. Mechanical bonding, such as needle punching, can also enhance abrasion resistance by interlocking the fibers. The Needle Punched Felt Machine page provides more information on how needle punching can be used to improve the properties of non - woven fabrics.
Fabric Density
Fabric density, which is related to the amount of fibers per unit area, has a direct impact on abrasion resistance. A higher - density fabric generally has more fibers in a given area, which means more points of contact and stronger resistance to abrasion. However, increasing the density too much can also make the fabric stiffer and less flexible, which may not be suitable for all applications.
Testing Abrasion Resistance
There are several standard methods for testing the abrasion resistance of non - woven fabrics. One common method is the Martindale abrasion test. In this test, a fabric sample is rubbed against an abrasive material under a specific load for a set number of cycles. The amount of damage to the fabric, such as weight loss, loss of strength, or visible wear, is then measured. Another method is the Taber abrasion test, which uses a rotating platform with abrasive wheels to abrade the fabric.
Applications and Abrasion Resistance Requirements
Geotextiles
Geotextiles made from spunbond non - woven fabric are used in civil engineering applications such as soil stabilization, erosion control, and drainage. These fabrics need to have high abrasion resistance because they are often in contact with rough soil particles and are subject to mechanical stress during installation and use. The ability to withstand abrasion ensures the long - term performance of the geotextiles in these demanding environments.
Hygiene Products
In the production of hygiene products like baby diapers and adult incontinence products, the non - woven fabric used needs to have a certain level of abrasion resistance. Although the abrasion forces in these applications are relatively low compared to geotextiles, the fabric still needs to maintain its integrity during normal use and handling. A fabric with poor abrasion resistance may tear or pill, which can affect the functionality and comfort of the product.
Automotive Interiors
Spunbond non - woven fabrics are used in automotive interiors for applications such as seat covers, headliners, and door panels. These fabrics need to withstand abrasion from daily use, including friction from passengers getting in and out of the vehicle and contact with clothing. High - quality spunbond non - woven fabrics with good abrasion resistance can ensure a longer lifespan and better appearance of the automotive interior components.
