Eco-friendly durable press finishing of textile interlinings

In co-operation with the Slovene textile company ZVEZDA which produces textile interlinings, we studied the influence of different durable press finishers on the release of formaldehyde. This was measured by the standard method Law 112 (Control of Household Products Containing Harmful Substances, Law 112). The effect of durable press finishing was evaluated by measuring the dimensional stability of treated fabrics and by wrinkle recovery angle measurements (WRA). In our research we studied the addition of formaldehyde acceptors in the form of urea, N-ethylurea and H-1-benzotriazole to the treating baths, to reduce the amount of free formaldehyde on the knitted textile substrate.
