Immediate 3E profits

Black Magic is a newly patented “No rinse”process for discontinuous bleaching. It exhibitsthe following advantages:

Efficiency

Maximal absorbencyHigh degree of whitenessNo cellulose degradationBetter uniformityBetter dyeabilityBetter “matching”

Economy

Less water (-50%)Less time (-50%)Less energy (-40%)Shorter cycle time (-1h)Higher machine productivityLess labour costs

Ecology

No rinsing neededNo neutralization neededLess waste waterLess alkaline amountBio-killing of residual peroxidewith enzymes

Bactosol ARL liquid conc.

Bactosol ARL liquid c is a powerful enzyme for the bio-removal of hydrogen peroxide. Itsubstitutes all sulfur and nitrogen-based reducingagents normally used as peroxide killers.

pH flexible (6 to 8)Temperature flexible (20 to 60 °C)Application flexible(continuous-discontinuous)Ecological

There is no more need for perfectly adjusted pHand temperature: the peroxide elimination is totalin each case!

Sirrix NE liquidSirrix NE liquid is a strong neutralizing agent. Itssynergetic association of organic acids allows aperfect adjusting of the desired pH on the wholerange.
