To produce finished denim garments, denim washing processes are required.In the complete finishing process of denim garment washing, all procedures including desizing, abrasion and bleaching take water as the processing medium.This is why water provide the required temperature for the denim washing process and form the stable environment for enzymatic reactions.It can also dissolve and flush away various impurities on the fabric surface, making it an indispensable basic medium for denim washing processing.
The water dosage must be strictly controlled in denim washing processes, as water consumption determines the level of production costs.If the bath ratio is too low and the water intake is insufficient, part of the denim fabric will be exposed above the surface of the treatment liquor.This will intensify mechanical friction between fabrics and washing equipment, easily causing linear crease defects on the cloth surface. Meanwhile,insufficient contact between fabrics and chemical reagents drastically weakens washing effects such as abrasion treatment and anti-staining.In contrast,If the bath ratio is too high.It must increase the dosage of enzyme so that promise the quality of denim garments.It will directly raises raw material production costs and leads to substantial waste of water resources.
How to achieve water-saving denim washing and cut production costs?BBT ENZYME neutral cellulase NEF®GP3 are launched by BBT to solve the industry problem.It is a granular neutral cellulase combine in textiles.NEF® GP3 realize the desizing and abrasion in one step.Recommended process parameters: system pH 6.0–7.0, processing temperature 30–50 ℃, reaction time 30–50 min, and production bath ratio of 1:4 to 1:8.This product can replace pumice stones. With the integrated one-bath desizing and abrasion process, it eliminates the separate water rinsing step after desizing in conventional procedures. No additional water refilling is required for enzymatic abrasion treatment, drastically cutting overall water consumption. Meanwhile, BBT ENZYME NEF®GP3 has a low degree of indigo back staining andgood anti back staining performance, providing an efficient processing solution for denim washing that saves water and reduces production costs.
