Safety
A flexible, controlled abrasive surface limits sharp impact in denim washing.
Saving
Achieves lower cost of labour, water usage, storage and transportation costs.
Efficiency
Uniform, consistent particle sizes support predictable batch-to-batch washing results.
A controlled material platform
Traditional stonewash character. Engineered consistency.
No sharp fragments
Uniform engineered shape avoids broken sharp corners, preventing snags and scratches on denim fabric.
Predictable wear behavior
Consistent abrasion rate means media performance stays predictable across its full service life, with no sudden drop in effect.
Less sludge residue
Lower break-down rate reduces mineral sludge buildup inside the drum, cutting down frequent drum cleaning and labor.
Low-water process compatible
Works well with low-water washing recipes, helping reduce overall wastewater discharge and treatment load.
