Switzerland: Sanitized unveils wash-resistant Sanitized Odoractiv 10
Sanitized has come out with a new process for odour management
in functional polyester textiles with wash-resistant Sanitized Odoractiv 10,
which has a dual-action effect - on the one hand it prevents bacteria from
docking on the textile, on the other, it adsorbs odours whilst the garment is
being worn. The technology was awarded the Swiss Technology Award.
Manufacturers of functional polyester textiles
face the same challenge: freshly washed garments develop an unpleasant odour
even after a short wearing period. The cause of this undesirable effect is not
the human perspiration itself, but the bacteria that break down the
perspiration. This process of decomposition generates the characteristic sweet,
pungent smell. Once the bacteria, or the odour molecules, have penetrated into
the surface of the polyester textile, they remain there permanently. Machine wash cycles and special detergents will never completely
eliminate them. The bacterial colonisation produces a biofilm on the polyester,
which not only causes unpleasant odours, but also has a negative impact on the
properties of the material.
This is exactly where the new, dual-action
technology from Sanitized comes into play: the surface of the textile is
"coated" with Sanitized Odoractiv 10 in the padding process. This
creates a protective film on the surface of the textile. The bacteria use this
anti-adhesive protective film as the basis for latching onto the garment. The bacteria
can therefore be completely washed out in a normal wash cycle, consequently
preventing any biofilm from forming. An anti-adhesion test method was developed
in cooperation with EMPA to prove this Wash Effect.
The second advantage is that Sanitized Odoractiv 10
has a high adsorbing effect. Odours are "trapped" and removed during
a normal wash cycle. The new product is the result of a technology that has
been further developed and was awarded the Swiss Technology Award. The odour
adsorption is identified using GC-MS. As
the product manager at Sanitized, Urs Zihlmann, puts it: "Sanitized
Odoractiv 10 marks the end of permastink in polyester textiles." Sanitized Odoractiv 10 can be
combined with other sanitised products, in particular with products based on
zinc pyrithione. The treatment does not influence the feel of the final treated
textile.
The odour-reducing function is clearly still going
strong even after 50 wash cycles. This is even the case if garments are washed
at 30 degree Celsius, either by hand or in the machine, meaning consumers save
on water and energy, not to mention that the piece of clothing will look great
for longer. As with all
its other products, Sanitized does not use any nano technology. The Hohenstein
Institute has awarded the company the rating Skin Friendly, the bluesign
registration is underway. The product also bears the label Eco Passport by
Oeko-Tex.
"The unique, dual Odour Control Function of
Sanitized Odoractiv 10 enjoys a unique position in the market and it
furthermore fulfills two market requirements: the prevention of permastink and
the minimisation of odour intensity during wear. Almost all manufacturers of
functional polyester textiles are confronted with this problem," commented
Zihlmann. "The new technology creates tangible added value for consumers.
This is a competitive differentiating advantage for global marketing."
