Odour management without biocide
• Presence of smell is perceived as unhygienic
• Usually, anti-odour finish is achieved by using antimicrobial products to control the growth of bacterias
• NEW: Anti odour finish without any biocides!!
• NouWELL CDL keeps textiles odour free
• Enhances freshness and keeps you feeling and smelling fresh
• Reduces odour development
• Excellent performance especially on synthetics
Well-being and the feeling of freshness are closely linked. Smelly clothes after sport activities or a visit to a restaurant might be unpleasant but cannot always be changed or washed immediately. NouWell CDL helps to preserve the feeling of freshness for a longer period of time. From an ecological point of view, it is advantageous if a textile equipped with NouWell CDL can skip a wash cycle.
The environment is protected through less consumption of water, energy, surfactants and the reduced entry of microplastics in synthetic textiles.
Normally, odour reducing finishes are achieved with biocides. This is not the case when using NouWell CDL.
A natural freshness can be obtained without any antimicrobial properties. In addition to the ecological advantages of finishing with NouWell CDL and its functionality, the ecological and toxicological safety of the product is very important to us.
This is con-firmed by our listing in various standards such as Oeko-Tex® Standard 100, ZDHC and bluesign®.
NouWell CDL: Tested effectiveness
Odour is perceived on textiles when odour molecules are released from the textile and carried away by air streams. The adsorption capacity of odour molecules depends, among other things, on the fabric material.
Synthetic textiles in particular, such as functional underwear or upholstery fabrics, hardly adsorb odours, which is noticeable as unpleasant odours on the fabric. Here, NouWell CDL helps to complex unpleasant smelling substances and retain them until the next wash cycle, where they are removed. Washing permanence can be achieved by appropriate recipe design.
Detection methods for effectiveness on textiles
The odour inhibiting effect can be determined by practical panel tests. Textiles finished with NouWell CDL exhibit a significantly lowered smell than comparable samples without the finish. The test substances range from perspiration components such as isovaleric acid to cigarette smoke and other unpleasant and pleas-ant odours.
An objective measurement of odour adsorbing properties is provided by ISO 17299-3 using gas chromatography. Here, the textiles are usually impregnated with isovaleric acid and the odour reduction rate is then determined by instrumental analysis. The following graphic shows exemplary results of different fabrics.
