Abstract
Abstract This invention provides new condensation products which are obtained by reacting a monocyclic or dicyclic heterocyclic compound having 5 to 7 ring members, at least two members being nitrogen and at least two halogen atoms being linked directly with the carbon atoms of the heteroring, with a thiourea compound or an alkali or ammonium hydrogensulfide and a mono- or dialkanolamine. These condensation products are useful as agents for textile finishing, especially for improving crease resistance and abrasion resistance.
