Product Description
Our cotton-polyester impregnated cloth is engineered specifically as a high-performance abrasive back cloth, available in X weight to meet precise industrial grinding needs.
Crafted from a balanced blend of cotton and polyester, this fabric combines the best of both materials: cotton contributes exceptional toughness and flexibility, ensuring the cloth conforms well to varying surfaces during grinding, while polyester adds superior abrasion resistance and dimensional stability, even under repeated friction and stress.
The advanced impregnation process further enhances its performance: it strengthens the fabric’s structural integrity, improves resistance to oils, solvents, and moisture, and creates a stable base that bonds reliably with abrasive grains (such as sand, alumina, or silicon carbide). This makes it an ideal backing material for a range of abrasive tools, including sandpapers, sanding belts, and grinding discs.
With its X weight specification, this cloth strikes the perfect balance between thickness and rigidity—providing ample support for aggressive grinding tasks without sacrificing maneuverability. It performs consistently across diverse applications, from metalworking and woodworking to plastic finishing, ensuring long tool life and smooth, uniform results.
Whether you’re manufacturing industrial-grade abrasives or sourcing reliable backing materials, our cotton-polyester impregnated abrasive back cloth delivers durability, compatibility, and performance you can depend on.
The post-processing of abrasive back cloth fabric includes the following steps:
1. Singeing: Removing surface hairiness and fluff from the fabric by passing it over a flame or hot surface to improve smoothness and appearance.
2. Desizing: Removing the sizing agent (applied during weaving to strengthen yarns) through chemical or enzymatic treatment to restore fabric absorbency.
3. Rinsing: Thoroughly washing the fabric to remove residual chemicals, sizing residues, and impurities from previous processes.
4. Dyeing: Applying colorants to the fabric using various methods (e.g., reactive, disperse, or acid dyeing) to achieve the desired hue and fastness.
5. Impregnation: Soaking the fabric in a liquid solution (e.g., resin, latex, or functional chemicals) to enhance properties like strength, elasticity, or water resistance.
6. Coating: Applying a thin layer of material (e.g., PVC, polyurethane, or acrylic) onto one or both surfaces of the fabric to add specific functions such as waterproofing, abrasion resistance, or barrier properties.
