Devan Chemicals Launches Allergen Control Tech at Heimtextil

At the Heimtextil home textiles show, being held through Jan. 13 in Frankfurt, Germany, Belgium-based textile company Devan Chemicals launched its Purissimo NTL bio-based allergen control technology.

Using probiotic encapsulation technology, the biodegradable additive can be applied to textiles during the finishing stage of manufacturing. Purissimo NTL’s shell is based on a natural cross-linked, bio-based polymer, which results in microcapsules that are up to 97 percent bio-based and readily biodegradable.

Purissimo NTL works by encapsulating dormant probiotic bacteria (spores). The microcapsule product is then integrated into textiles, where friction opens the capsules and releases the spores. Those spores absorb humidity, self-activate and start to multiply. The probiotic bacteria then consume allergens that cause allergic reactions and asthma. 

Purissimo NTL can be applied to a wide range of textiles such as mattresses, pillows, bedcovers and blankets, as well as upholstered furniture, carpets, curtains, public transportation and pet items, such as bedding. The finish is Oeko-tex compliant and has a wash durability of up to 30 washes.

Antimicrobial and anti-allergen additives have become a hot commodity in home textiles in recent years, escalated by pandemic-induced fears of disease. And with wellness and sustainability also important factors to consumers, there’s been a greater push to make these finishes environmentally friendly.

Recently, Noble Biomaterials launched its Ionic+ botanical antimicrobial finish in the home goods market with collaborations with Rest Duvet, Silvon Home and Standard Fiber.
