Definitions
- the present invention relates to the use of optical brighteners to improve the wash fastness of lightened textiles.
- the authenticity profile of optically brightened textile articles made of polyamide and polyamide / polyurethane blends includes high demands on light and weather fastness as well as high demands on wash resistance.
- Lightened items such as swimwear or underwear should suffer as little loss of white as possible during the washing process even after multiple washes. These requirements are primarily met by those polyamide (PA) or polyamide / polyurethane (PU) materials in which the brightener is applied during polymer production or using masterbatch technology.
- the brighteners used here generally have a high fastness profile.
- textile application processes such as e.g. Pull-out process, block thermosol process, block / steam or block washing process or acid shock process with and without reducing agents used.
- These processes are known to the person skilled in the art and can be found in relevant literature references. (e.g. R.Williamson, "Fluorescent Brightening Agents” in Textile Science and Technology pp. 63-69, Elsevier Scientific Publishing Company, Amsterdam, Oxford, New York 1980).
- the brighteners used in the textile application have the disadvantage, depending on their different affinities for the fiber, that they can be partially washed out again by subsequent washing processes. Surprisingly, it has now been shown that the wash-fastness of optical brighteners on polyamide and polyamide / polyurethane articles can be significantly improved if mixtures of certain optical brighteners are used.
- the invention thus relates to the use of a mixture of optical brighteners, which comprises
- At least one anionic brightener selected from the group consisting of derivatives of pyrazoline, which carry sulfonic acid or sulfonate groups, and those anionic brighteners, which in the
- anionic brightener which is a derivative of stilbene, which carries a sulfonic acid or sulfonate group on each of the two phenyl groups of the stilbene, and is likewise substituted on both phenyl groups of the stilbene with a nitrogen-containing, aromatic heterocycle, for the preparation of brightened polyamide - And / or polyurethane fibers, which show an improved wash fastness of the optical brightening.
- component B which are preferably in the mixture at 25% by weight or less, based on the total brightener weight, are sufficient to achieve an improvement in the fastness to washing of the lightening effects of component A).
- Component A) of the brightener mixture is preferably a derivative of pyrazoline which carries substituents with sulfonic acid or sulfonate groups.
- substituents are preferably aromatic substituents which carry halogen or alkyl radicals.
- the alkyl radicals can include heteroatoms.
- the sulfonic acid or sulfonate groups are either on the aromatic substituents or on the alkyl radicals.
- substituents are understood in particular to mean phenyl, naphthyl, biphenyl and anthracenyl.
- Ar 1 and Ar 2 independently of one another are sulfonated and further substituted or unsubstituted aryl radicals, in particular sulfonated phenyl, biphenyl or naphthyl radicals, which are further substituents such as hydroxy, (Ci-C ⁇ J-alkyl, (C ⁇ -C 6 ) alkoxy, Halogen, hydroxyalkyl, amino, alkylamino, acylamino, carboxyl, alkoxycarbonyl, sulfonic acid ester, alkylsulfonyl, arylsulfonyl, sulfonyl and sulfonamide groups, and R 15 and R 15 , which may be the same or different, Hydrogen, (-CC 4 ) alkyl or phenyl mean.
- R 16 is halogen or (CrC 6 ) alkyl
- R 17 is a substituted or unsubstituted (CrC 6 ) alkoxycarbonyl, Sulfonamide or sulfonic acid group
- m is zero, 1, 2 or 3.
- Preferred pyrazoline brighteners are shown in the formulas (3) to (5):
- optical brighteners as component A of the mixture are as follows:
- Component B of the mixture of optical brighteners is a stilbene derivative which generally corresponds to formula (13):
- R stands for an aromatic, nitrogen-containing heterocycle.
- This heterocycle is preferably derived from triazole or triazine.
- Particularly preferred compounds for component B are:
- Example 4 As described in Example 1, 0.8% of the brightener of the formula 16 and 0.2% of the brightener of the formula 20 are used for the brightening. The whiteness achieved is 230. After 5 washes according to Example 2, 213 whiteness are still obtained, a significant improvement over the white effects using brightener 16 alone. Example 4
- Example 2 For brightening, as described in Example 1, 0.8% of the brightener of the formula 17 and 0.2% of the brightener of the formula 20 are used. The whiteness achieved is 223. After 5 washes according to Example 2, 214 whiteness are still obtained, a significant improvement over the whitening effects of brightener 17 alone.
- the degree of whiteness is 233. After 5 washes in accordance with Example 2, 220 degrees of whiteness are still obtained, a marked improvement over the whitening effects of the brightener of formula 18 alone.
- Example 2 For brightening, as described in Example 1, 0.9% of the brightener of formula 19 and 0.1% of the brightener of formula 20 are used. The whiteness achieved is 223. After 5 washes according to Example 2, 201 whiteness are still obtained, a significant improvement over the whitening effects of brightener 19 alone.
- Example 2 After five washes according to Example 2, 195 degrees of whiteness are still obtained, a significant improvement over the washing effects of Example 2 when brightener 16 is used alone.
- Example 2 For brightening, as described in Example 1, 0.5% of the brightener of the formula 16, 0.25% of the brightener of the formula 20 and 0.25% of the brightener of the formula 18 are used. The whiteness achieved is 226. After five washes according to Example 2, 216 whiteness are obtained.
