• the invention relates to a process for the permanent finishing of fibre materials to render them antistatic and dirt-repellent and, optionally, antimicrobial; to the finishing preparation; as well as to the fibre material, as industrial product, finished by application of the said process.
• the method is known of rendering fibre materials solely antistatic or solely dirt-repellent. Textile materials possessing a good antistatic finish, however, frequently display a greater tendency to become stained, or the dyeings produced thereon have an inferior fastness to rubbing; and the dyeings on materials of which the finish is effectively dirt-repellent exhibit very often a tendency to vary in shade. It is also possible to impart to fibre materials simultaneously an antistatic and dirtrepellent finish; the treatment of the materials at temperatures of over 100C required to obtain these effects, however, leads in many cases to an appreciable impairment of the fastness to rubbing, and/or to a loss of the acquired finishing effects. The combination of specifically favourably acting components does not,
• fibre material treated in such a manner frequently has, moreover, disadvantages in that, for example, the handle of the material is unfavourably affected, and the dyeing thereof suffers a dulling effect or displays a variation in shade.
• a single-bath process has now been found which makes possible, in a surprising manner, the permanent finishing of fibre materials, preferably dyed textile fibres, e.g. dyed textile floor-coverings, so that the treated material is rendered simultaneously pennanently antistatic and dirt-repellent and, optionally, antimicrobial, the material possessing a completely soft handle, the said effects being obtained without appreciable impairment of the fastness to rubbing of the dyeing.
