Nonwoven fabrics are manufactured sheets made from fibers or filaments bonded together. These versatile materials are used for a wide range of applications from medical supplies to consumer products. Spunbond nonwoven fabrics are a common nonwoven fabric type that utilize continuous spun filaments.
Spunbond nonwoven fabrics are typically supplied in large roll form, making them convenient and cost-effective for many uses. Here are the key things to know about spunbond nonwoven fabric rolls:
How Spunbond Nonwoven Rolls Are Made
Spunbond nonwoven rolls are manufactured using a process called spunbonding. In this process, polymer resin pellets are melted and extruded through tiny holes called spinnerets to create continuous filaments.
The hot filaments are then drawn by air knives and quench drums to cool and attenuate them to the desired fineness. The filaments are then randomly deposited onto a conveyor belt in a random web. The filaments are bonded together using mechanical, thermal or chemical bonding methods.
The continuous spunbonded web is wound onto large rolls. These nonwoven fabric rolls can range from 1 to 4 meters in width and up to several kilometers in length.
Width, Length And Thickness Of Rolls
Spunbond nonwoven fabric rolls are typically available in widths from 1 meter up to 4+ meters wide, depending on the production line. Roll lengths vary but can reach several kilometers long, providing high bulk quantities of fabric.
Roll thickness ranges from very thin materials around 0.03 mm to thicker spunbond nonwoven rolls over 1 mm in thickness. Fabric weight also varies from 15 gsm to 200 gsm and over for heavy-duty uses.
Material Composition & Properties
The majority of spunbond nonwoven rolls are made from polypropylene fibers. However, polyethylene and polyester spunbonded rolls are also available. Depending on material composition and bonding method, spunbond nonwoven rolls can exhibit properties including:
• Softness • Opacity
• Strength • Breathability
• Absorbency • Chemical resistance
• Stretch • Thermal insulation
Common Uses Of Spunbond Rolls
Due to their strength, barrier properties and cost effectiveness, spunbond nonwoven fabric rolls are used in a wide range of industries and applications. Here are just a few examples:
• Medical: Surgical drapes, gowns, face masks.
• Personal care: Baby wipes, diapers, feminine hygiene products.
• Filtration: Vacuum bags, furnace filters, face masks.
• Automotive: Interior liners and insulation.
• Home goods: Upholstery, mattress covers.
• Industrial: Matting, packing, tapes, wipes.
Spunbond Nonwoven Fabric Rolls Provide A Cost-effective & Versatile Material Solution
Nonwoven fabric rolls spunbond provides a cost-effective and versatile material solution due to their wide web widths, long lengths, range of thicknesses and varied properties. Understanding the manufacturing process and key variables that differ between rolls can help you choose the right spunbond nonwoven fabric for your specific application needs.
