The new preparation, which preferably contains optical brighteners as a treatment agent, is used in particular for lightening synthetic fiber materials, especially finished goods such as curtains or underwear.

Description

The present invention relates to a stable preparation of a treatment agent for textile substrates. In particular, it relates to a new, stable, concentrated or diluted liquid formulation of an optical brightener for brightening fiber materials, in particular finished products such as Underwear and especially curtains made of synthetic fiber materials, preferably polyester fibers.

In order to optically brighten unassembled textile material, the procedure is usually such that applying sparingly water-soluble optical brighteners to the textile material by means of a pull-out process or, in particular, by a padding process, and the material is then heat-set at temperatures above 100 ° C.

In the case of ready-made textile materials, this method proves to be practically impractical at high temperatures.

The attempts to use textile materials e.g. Lightening polyester curtains at lower temperatures has also so far not led to useful results.

The problem specified for lightening made-up textile materials also applies to the dyeing or finishing of these materials with e.g. Antimicrobials, softening agents, UV adsorbers, pigments, plasticizers or dirt-repellent agents.

It is therefore the object of the invention to find a new application system which also allows finished textile goods to be finished, dyed and in particular brightened optically at room temperature.

The solution to this problem is to use specific preparations, as described below, for the treatment, in particular when optically brightening natural or synthetic fiber materials, preferably textiles made of polyester fibers or blended fabrics with a predominant polyester content and, above all, curtains made of polyester fibers. These preparations have a correspondingly pronounced effectiveness. You can directly use a treatment bath, e.g. a rinse liquor, added and then even at room temperature in a short time on the substrate as an alkali washable or possibly permanent, equipment.

The white pigment used in this example is produced as follows.

und

3 parts of titanium white and 47 parts of polyester (polyethylene glycol terephthalate) are dissolved in 650 parts of y-butyrolactone in a pressure vessel with stirring and under an inert gas atmosphere for 20 minutes at 190-195 ° C and then allowed to cool slowly to room temperature, with the polyester being entrained of the titanium dioxide pigment in the form of a fine, flocculated precipitate (primary particle size 1-2 microns). The precipitated product is filtered off and in an aqueous liquor containing 0.07% of two optical brighteners of the formulas, based on the white pigment coated with polyester

and

contains finely dispersed, treated at a liquor ratio of 1:20 for 30 minutes at 130 ° C. The white pigment treated in this way is then filtered off, rinsed and dried. The resulting titanium white coated with polyester fluoresces blue-violet under UV light.

Instead of titanium dioxide, it is also possible to use other very finely divided white pigments such as barium sulfate, magnesium oxide, zinc oxide, zinc sulfide, aluminum hydroxide, calcium carbonate or urea-formaldehyde condensates, for example with a BET surface area of 3 to 75 m ² / g, preferably 5 to 25 _m ² _/ g coated with polyester in the same way and then treated with the same brightener mixture. Such fluorescent lipophilic white toners can also be incorporated into the preparation (25) and applied successfully to curtains.

Example 19:

eingerührt und während 30 Minuten bis zur vollständigen Auflösung bei 70°C gehalten, so resultiert nach Abkühlen eine weitere Präparation (26) die auf gleiche Weise wie in Beispiel 18 beschrieben auf eine gewaschene Polyestergardine appliziert wird. Man erhält eine Gardine mit noch gesteigerten Weisseffekten. Die auf die Gardine aufgebrachte, am UV-Licht stark blau fluoreszierende Beschichtung lässt sich in einem alkalischen Waschgang wieder vollständig entfernen.The preparation (23) described in Example 18 is additionally 0.35% of an optical brightener of the formula (101) and 0.002% of a violet shading dye of the formula

stirred in and kept at 70 ° C. for 30 minutes until completely dissolved, this results in a further preparation (26) which is applied to a washed polyester curtain in the same manner as described in Example 18. You get a curtain with enhanced white effects. The coating applied to the curtain and strongly blue fluorescent due to UV light can be completely removed in an alkaline wash.
