In the textile suede finishing process, the nap texture of the fabric depends entirely on the grinding state of the brush filaments on the roller. However, for a long time, ordinary abrasive filaments have frequently caused headaches for workshops during high-speed, continuous operation:

• Weak bonding between low-grade silicon carbide and the nylon substrate: Under high-speed operation, grit and powder shedding occur extremely easily. This not only scratches fabrics and precision workpieces, but the generated dust also pollutes the workshop environment and clogs equipment, directly increasing the defect rate.

• The industry paradox between brittleness and toughness: Strong grinding force easily leads to broken filaments; once toughness is enhanced, the cutting performance decreases. Balancing "grinding force" and "rebound resilience" has long been a challenge.

• Short service life and frequent downtime: Conventional carbon suede rollers begin to experience filament sagging and deformation after processing around 800 tons, resulting in color inconsistency across fabrics.

To address these pain points, Daxing has introduced GrindFil—specialized silicon carbide abrasive filaments tailored for carbon suede finishing rollers.

Core Competitive Advantages
Scientific Formulation: Compound-engineered using 240# silicon c arbide and high-grade Nylon 612, featuring a 0.7 mm standard filament diameter, an abrasive concentration of approximately 12%, and long-term temperature resistance. Following a 200-hour continuous fatigue test, the filaments remain upright without sagging or deformation. Experimental data demonstrates that blindly pursuing an excessively high abrasive ratio easily leads to filament breakage, whereas the 12% scientific ratio strikes the optimal balance between cutting force and service life.

Significant Reduction in Overall Costs: Purpose-built for carbon suede finishing rollers, delivering a stable processing lifespan of up to 1,200 tons. This substantially reduces downtime caused by frequent roller replacements and repeated machine adjustments or trial runs, helping printing and dyeing mills and equipment suppliers secure stable quality and compress costs right from the source.

Customized Solutions for Diverse Fabrics:

Backed by adjustable formulations to meet varied textile processing demands:

• Heavyweight Fabrics (e.g., denim, canvas over 320g/m2): Utilizing 0.7 mm high-rigidity filaments offering strong cutting force and thorough pile opening. Processes that previously required imported suede rollers to pass twice can now meet standards in a single pass with GrindFil, directly doubling production capacity.

• Sensitive and Delicate Fabrics (e.g., Tencel, Modal): Customized with finer, softer filaments coupled with optimized tufting density, delivering a delicate peach-skin finish while fundamentally eliminating the risks of snagging and tearing.

The performance of a carbon suede finishing roller hinges on the stability of its matching filaments. GrindFil filaments are precision-engineered for carbon suede rollers, offering an extended service life and minimizing frequent roller-change downtime and trial adjustments. They empower dyeing mills and roller manufacturers to stabilize quality and lower total production costs from the source.
