Conventional denim abrasion fading mostly adopts pumice stone washing technology, yet this processing method comes with numerous drawbacks. The launch of neutral cellulase has specifically solved these problems . By conducting bio-finishing on denim fabrics with neutral cellulase, we can replicate the visual texture of pumice stone washing and create layered bleached appearances.

Neutral cellulase hydrolyzes cotton cellulose in denim. The longer the treatment time, the more surface fibers are stripped off, which reduces fabric tensile strength and makes finished garments prone to tearing.Enzymatic treatment duration exerts a decisive influence on fabric weight loss. Properly controlled processing time removes size and surface fuzz from grey denim, alleviating its stiff hand feel and delivering enhanced softness and skin-friendliness. In contrast, over-processing leads to excessive cellulose degradation and drastically weakens fabric durability.Denim is dyedwith indigo that only adheres to the fiber surface. Prolonging the enzyme washing time will strip more loose surface dye and degrade the quality of denim fabrics.

Therefore, when using neutral cellulase for denim abrasion fading, the enzymatic treatment time must be reasonably controlled, so as to achieve the ideal stone-wash effect on denim while guaranteeing fabric quality.

Choose BBT ENYZME neutral cellulase NEF® 2200+ and Neutral celluase NEF® 2200+ is used in abrasion processes in textile denim garment washing.A 40-minute treatment at 55°C get big grain. NEF® 2200+ features good enzymatic stability. Consistent quality across different batches can be achieved without repeated adjustment of processing time.NEF® 2200+ eliminates the need for pumice stones, resolving drawbacks of conventional stone washing while maintaining premium denim quality. It serves as an eco-friendly and cost-effective preferred solution for denim washing factories.
