Belgian textile innovator Devan Chemicals launched “Purissimo NTL”, a biobased and readily biodegradable allergen control technology. It is based on the well-known probiotic encapsulation technology and can be applied to textiles during the finishing stage of the textile manufacturing process. The technology is based on encapsulated probiotics, which are natural microorganisms similar in kind to those you can find in yoghurt, cheese and other probiotic food.

The company introduced probiotics in textiles already in 2010. “Purissimo NTL” is based on Devan’s already well-established probiotics, incorporated into a new microcapsule shell. The shell is based on a natural crosslinked biobased polymer, which results in microcapsules that are up to 97 % biobased and readily biodegradable (OECD 301B).

Firstly, dormant probiotic bacteria (spores) are encapsulated. The microcapsule product is then integrated into textiles. Friction opens the capsules and releases the spores. The spores absorb humidity, self-activate and start to multiply. The probiotic bacteria start to consume the allergens that cause allergic reactions and asthma. Due to lower allergen concentration, individuals with respiratory allergies such as house dust mite matter, pet allergens and pollen allergens will have milder to no symptoms and hence a better well-being feeling.

“Purissimo NTL” can be used on a wide range of textiles such as mattresses, pillows, bedcovers, blankets but also upholstered furniture, carpets, curtains and public transportation and pet items, such as bedding. It is Oeko-tex compliant, has a long-lasting effect and a wash durability up to 30 washes is achievable.
