Standard PP Spunbond Nonwoven
Spunbond (Vliseline) – High-Quality Non-Woven Polypropylene Fabric
Spunbond is a thermally bonded non-woven material made from polypropylene melt, formed through a draw plate extrusion process. During production, fine continuous fibers are extruded, stretched in an air stream, and laid on a conveyor to form a textile web. These fibers are then thermally bonded, ensuring strength and durability. This process allows for fabric densities ranging from 11 g/m² to 140 g/m².
Key Properties
✅ Geometric Specifications: Roll width up to 1.6m, customizable length.
✅ Density Options: 11 g/m² to 140 g/m² to suit various applications.
✅ Color Variety: Available in white, beige, brown, black, pink, cyan, red, blue, yellow, light green, and more.
Applications
Thanks to its unique production process and diverse physical and mechanical properties, Spunbond is widely used across multiple industries:
✔ Textile & Upholstery: Used in furniture, orthopedic mattresses, covers, and bags.
✔ Agriculture: Functions as agrotextile and covering fabric.
✔ Hygiene & Medical: Ideal for hygienic products and disposable medical clothing.
✔ Construction: Serves as a base for waterproofing membranes and insulation materials.
These fabrics exhibit uniformity and dimensional stability. Polypropylene fabrics necessitate the incorporation of additives for ultraviolet (UV) and heat stability. They are available in various specifications and a range of colors.
Uniformity: PP spunbond nonwoven fabrics are known for their consistent texture and even distribution of fibers across the fabric. This uniformity is crucial for applications requiring reliable performance, such as in medical and hygiene products.
Dimensional Stability: These fabrics maintain their shape and size under various conditions, making them reliable for use in products that must retain their form during use and after processing.
Strength: The spunbond process produces fabrics that are strong and durable, suitable for demanding applications.
Additives:
Ultraviolet (UV) Stability: PP fabrics, by nature, degrade under prolonged exposure to UV light. To counter this, UV stabilizers are added during manufacturing. These additives enhance the fabric’s resistance to sunlight, preventing degradation and extending the product’s life in outdoor applications, such as agricultural covers or outdoor furniture.
Heat Stability: Polypropylene has a relatively low melting point (around 160°C), and prolonged exposure to heat can cause it to degrade. Heat stabilizers are therefore added to improve the fabric’s resistance to thermal aging, making it suitable for applications where the fabric may be exposed to higher temperatures.
Specifications:
Weight (GSM): PP spunbond fabrics are available in a wide range of grammages, typically from as low as 10 grams per square meter (GSM) up to over 200 GSM. Lower GSM fabrics are lightweight and often used in disposable items, while higher GSM fabrics offer more durability and strength for industrial applications.
Thickness: The thickness of the fabric can vary depending on the specific requirements of the application. Thicker fabrics provide more strength and insulation.
Width: The fabric can be produced in various widths, depending on the machinery and the specific application, ranging from narrow rolls for small-scale uses to wide rolls for large-scale industrial applications.
Colors:
Customizability: PP spunbond nonwoven fabrics can be produced in a wide range of colors. This versatility allows for customization according to the aesthetic or functional needs of different applications, whether for branding, visibility, or specific functional requirements (e.g., color-coded products in medical settings).
Applications:
Medical and Hygiene Products: Due to their uniformity and ability to be produced in lightweight forms, PP spunbond fabrics are commonly used in products like surgical gowns, masks, diapers, and sanitary napkins.
Agriculture: UV-stabilized versions are used in applications such as crop covers, ground covers, and nursery bags.
Construction: The dimensional stability and strength of these fabrics make them useful in construction, for example, in roofing membranes, geotextiles, and insulation.
Packaging: Spunbond fabrics are also used in packaging, especially where breathable yet durable materials are required.
Advantages:
Cost-Effective: PP spunbond fabrics are generally affordable, making them a cost-effective solution for a wide range of applications.
Recyclability: Polypropylene is recyclable, which makes these fabrics more environmentally friendly compared to other non-recyclable materials.
