Ask any textile finisher to name the hardest challenge in functional finishes, and wash durability will be at the top of every list. For moth protection specifically, the commercial benchmark is 20 to 30 wash cycles a standard that most natural actives, applied conventionally, do not meet beyond five cycles.
At Innoleague Technologies India Pvt Ltd, wash durability is not an afterthought. It is engineered into the technology from the ground up, through three interlocking mechanisms.
The first is encapsulation itself. By isolating the active within an aminoplast thermoset shell, we prevent the aqueous wash liquor from directly accessing and dissolving the active ingredient. The capsule’s polymer shell resists the surfactants and mechanical action of domestic and commercial wash cycles. What would normally leach out in the first wash is retained within the capsule held for release only under the specific conditions of end use.
The second is the application system. Our capsule suspension is padded onto a wool substrate with a textile binder that mechanically and chemically anchors the capsules to the fibre surface. The binder concentration, padding pressure, and curing temperature profile are calibrated to maximise fibre adhesion without compromising handle, drape, or fibre properties.
The third is controlled-release architecture. Unlike a surface coating that depletes linearly, our encapsulated actives release through a combination of slow permeation through the shell wall and mechanical rupture under use friction. The protection is therefore not only retained through washing it is also triggered more effectively under actual use conditions.
Our durability testing, conducted in collaboration with the Wool Research Association of India, systematically measures residual moth mortality at successive wash intervals, building the durability profile required for industry acceptance and certification alignment.
