Spunbond polypropylene fabric

Oue spunbond nonwoven fabric is a type of nonwoven textile made from thermoplastic polypropylene (PP) fibers that are bonded together by a thermal process. The process involves extruding the PP fibers, which are then spun and laid down in a random pattern to create a web. The web is then bonded together to form a strong and durable fabric.

The characteristics of PP spun bond non woven fabric

Polypropylene spunbond non-woven fabric has the characteristics of lightweight, breathability, durability, waterproofing, anti-static, and environmental protection.Polypropylene spunbond non woven fabric is a lightweight material with the characteristics of light weight and strong load-bearing capacity. This makes it an ideal alternative material, suitable for many fields such as healthcare, household products, etc. Meanwhile, due to its lightweight, it is also more convenient to carry and install.

 pp spunbond non woven fabric uses

PP spunbond nonwoven fabric has a wide range of uses across agriculture、 construction、packaging、 geotextiles、automotive、home furnishings. Spunbonded nonwoven fabric is a product with development potential, which fully utilizes the advantages of fibers as healthcare materials. It is a product of the emerging industry discipline formed by the integration and intersection of multiple disciplines and technologies. This includes surgical gowns, protective clothing, disinfectant bags, masks, diapers, household cloths, wiping cloths, wet face towels, magic towels, soft tissue rolls, beauty products, sanitary pads, and disposable sanitary cloths.

Comprehending the spin bonding process

The technique of spunbonding, used to make nonwoven fabrics, entails extruding thermoplastic polymers, most often polypropylene (PP), into continuous filaments. After that, the filaments are arranged into a web shape and fused together to make a robust, long-lasting fabric. Many desirable features, such as high strength, breathability, water resistance, and chemical resistance, are present in the resulting PP spunbond nonwoven fabric. This is a detailed explanation of the spunbonding procedure:

1. Extrusion of polymers: Extrusion of the polymer via a spinneret, usually in the form of pellets, is the first step in the process. The molten polymer is driven under pressure through the spinneret’s many tiny holes.

2. Filament spinning: The polymer is stretched and cooled as it comes out of the spinneret to create filaments that are continuous. Usually, these filaments have a diameter of 15–35 microns.

3. Web formation: To build a web, the filaments are then gathered in an arbitrary pattern on a moving conveyor belt or drum. The weight of the web is typically 15–150 g/m².

4. Bonding: To bind the filaments together, the web is subsequently exposed to heat, pressure, or chemicals. Numerous techniques, such as heat bonding, chemical bonding, or mechanical needling, can be used to accomplish this.

5. Finishing: After bonding, the fabric is usually calendered or given a finish to enhance its performance characteristics, like water resistance, UV resistance.
