In the world of surface finishing and material processing, non-woven abrasive fleece stands out as a versatile and efficient tool. Often referred to as abrasive fleece or non-woven abrasives, this material is engineered for tasks requiring precision, flexibility, and minimal damage to the workpiece. Whether you’re in metalworking, woodworking, or automotive manufacturing, understanding non-woven abrasive fleece can help optimize your processes for better results. In this article, we’ll explore what it is, how it’s made, its types, applications, benefits, and highlight top products from Atlantech Process Technology.

What Is Non-Woven Abrasive Fleece?

Non-woven abrasive fleece is a three-dimensional web of synthetic fibers, typically nylon or similar materials, embedded with abrasive grains and bonded together using resin. Unlike traditional woven fabrics or bonded abrasives, it doesn’t have a woven structure—instead, it’s created through a non-woven process that results in a flexible, open matrix. This design allows for even distribution of abrasive particles like silicon carbide (SiC) or aluminum oxide (Al2O3), making it ideal for applications where low pressure and controlled material removal are key.

The term “fleece” evokes a soft, fabric-like texture, which accurately describes its cushioned and pliable nature. This material is clog-resistant due to its open structure, which self-cleans during use by exposing fresh abrasive grains as the surface wears. It’s commonly available in forms like rolls, pads, discs, and brushes, catering to both manual and automated operations. For example, Atlantech offers Non-Woven Abrasive Brushes designed for various industrial applications.

How Is Non-Woven Abrasive Fleece Manufactured?

The manufacturing process of non-woven abrasive fleece involves bonding synthetic fibers (such as Nylon 6.6) with abrasive media and resins under controlled conditions. Fibers are first carded or air-laid to form a web, then impregnated with abrasives and binders. Heat or chemical processes cure the resin, creating a durable yet flexible product.

Variations include impregnation types: non-impregnated for maximum flexibility, PU-impregnated for added durability, or liquid-impregnated for enhanced wear resistance. This process ensures uniform grit distribution, leading to consistent scratch patterns and reproducible finishes. Atlantech Process Technology offers over 3,500 variants, customizing hardness, grit size, and dimensions to suit specific needs.

Types of Non-Woven Abrasive Fleece Products

Non-woven abrasive fleece comes in various forms, each tailored for specific tasks. Atlantech Process Technology provides a range of high-quality options, including:

Flap Brush Non-Impregnated provides high flexibility for light deburring and cleaning, while Flap Brush PU-Impregnated and Flap Brush Liquid-Impregnated offer greater hardness for heavy-duty applications like oxide removal.
  • Convolute Brushes: Spiral-wound fleece around a core, such as Convolute Brush PU-Impregnated or Convolute Brush Liquid-Impregnated, designed for vibration-free operation and uniform finishing on contoured surfaces.
  • Disc Brushes: Disc Brush PU-Impregnated is ideal for technical and decorative surfaces, offering flexibility and consistent line patterns.
  • Combi Brushes and Super Soft Brushes: Combi Brush combines non-woven fleece with abrasive cloth for increased material removal, while Super Soft Brush is perfect for delicate deburring tasks.
  • Rolls, Hand Pads, and Discs: Rolls, Hand Pads, and Discs are versatile for manual or machine use, ideal for large surfaces or spot work.
  • Bias Mops and Other Products: Bias Mops for specialized buffing and Further Products like belts for unique applications.
  • Accessories: Flanges made of aluminum, steel, or PVC to secure brushes in industrial setups.

Applications of Non-Woven Abrasive Fleece in Manufacturing Industries

Non-woven abrasive fleece is widely used across industries for its gentle yet effective action. Key applications include:

  • Metalworking and Fabrication: Deburring, rust removal, weld blending, and surface preparation on steel, stainless steel, aluminum, and non-ferrous metals using products like Flap Brush PU-Impregnated or Convolute Brush Liquid-Impregnated.
  • Automotive and Aerospace: Finishing components, removing burrs from aircraft parts, and achieving satin or matte effects with Combi Brush or Disc Brush PU-Impregnated.
  • Woodworking and Furniture: Sanding, polishing, and roughening wood surfaces for even finishes with Rolls, Hand Pads, and Discs.
  • Electronics and Plastics: Processing circuit boards, removing varnish, and matting plastic parts using Super Soft Brush.
  • Construction and Marine: Descaling flame cuts, cleaning strips, and preparing surfaces for coatings with Flap Brush Liquid-Impregnated.

It’s suitable for wet or dry use, making it adaptable for machines or manual sanding.

Benefits of Using Non-Woven Abrasive Fleece

The advantages of non-woven abrasive fleece make it a preferred choice over traditional abrasives:

  • Flexibility and Conformability: Adapts to contoured or uneven surfaces without gouging.
  • Clog-Resistance and Longevity: Open structure prevents loading, extending tool life.
  • Uniform Finishes: Produces consistent scratch patterns and roughness depths for decorative or functional surfaces with products like Convolute Brush PU-Impregnated.
  • Low Heat Generation: Minimizes workpiece discoloration and distortion.
  • Versatility: Works on metals, wood, plastics, ceramics, and glass; usable in dry, wet, or oiled conditions with Rolls, Hand Pads, and Discs.
  • Eco-Friendly Options: Some manufacturers focus on sustainable production, enhancing environmental benefits.

While less aggressive than bonded abrasives for heavy stock removal, its strengths lie in finishing and preparation tasks.
