Garmon's Nimbus chemical auxiliaries and dyes can be sprayed onto apparel and textiles within closed systems

Garmon Chemicals has developed a new way of finishing denim that "revolutionises" the traditional process of stone washing by spraying enzymes onto garments within closed systems such as washing machines.

Until now, spraying enzymes onto garments and textiles in the form of a fine mist has been considered a questionable practice due to the possible risk of airborne enzymes.

But by working with Tonello Garment finishing Technologies and enzyme producer Novozymes, negligible amounts of airborne enzymes have been detected using a specific procedure performed by spraying the Garmon ATB 710 enzymes in a Tonello Core washing machine.

The new Nimbus-z for enzymatic treatments is part of the wider Nimbus platform of chemical auxiliaries and dyes that can be nebulised or sprayed onto apparel and textiles within closed systems.

The process can be used for products such as resins, softeners, dyes and optical brighteners, and auxiliaries such as denim pre-treatments and dispersing agents.

Because of their delivery method, the Nimbus platform offers benefits including water savings of up to 80%, "significant" energy savings, and requires fewer chemicals because of the more efficient contact and reaction between active principles and substrates, Garmon says.

Denim treatments have historically gone through two main evolutions, explains Alberto De Conti, chief marketing officer at Garmon Chemicals: the 'Solid age' from the end of the 60s that used pumice stone, and the 'Liquid age' of the 90s when enzymes began to replace previous processes.

"With the step-changing innovation Nimbus-z the industry enters the 'Nebulisation age,' of safe enzymatic treatments through self-contained, nebulising systems."
