Belgian textile innovator Devan Chemicals will launch Purissimo NTL, a biobased and readily biodegradable allergen control technology, at the upcoming Heimtextil trade show in Frankfurt, which will be held from January 10–13, 2023. The technology is based on probiotic encapsulation technology and aims to improve the lives of people who suffer from allergies.

Purissimo NTL can be applied to textiles during the finishing stage of the textile manufacturing process. Devan introduced probiotics in textiles for the first time, way back in 2010, according to a press release by the company.

The technology, incorporated into a new microcapsule shell, is based on encapsulated probiotics, which are natural microorganisms similar in kind to those that can be found in yoghurt, cheese, and other probiotic food. The shell is based on a natural crosslinked biobased polymer, which results in microcapsules that are up to 97 per cent 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.

The natural allergen control technology cleans up pet dander, pollen, and house dust mite allergens in textiles throughout the home. Due to lower allergen concentration, individuals with respiratory allergies due to house dust mite matter, pet allergens, and pollen allergens will have milder to no symptoms and notice an improvement in their wellbeing, added the release.

Purissimo NTL can be used on a wide range of textiles such as mattresses, pillows, bedcovers, and blankets as well as upholstered furniture, carpets, curtains, and pet items, such as bedding. It is Oeko-Tex compliant and has a long-lasting effect with an achievable wash durability of up to 30 washes.
