Definitions
- the invention relates to a method for increasing the whiteness of polyester-containing textile material by combined application of optical brighteners with so-called boosters on the material.
- Compounds that absorb short-wave UV light and transmit the absorbed energy to the brightener are referred to as boosters.
- boosters Compounds that absorb short-wave UV light and transmit the absorbed energy to the brightener are referred to as boosters.
- Boosters are fluorescent compounds that absorb in the range from 300 to 350 nm and fluoresce at 350 to 390 nm. The fluorescence of the booster thus lies in the absorption range of the brightener, which leads to increased activity of the brightener and, with many brighteners, to a noticeable increase in the degree of whiteness of the treated polyester-containing textile material.
- the compounds which are suitable as a booster for an additional whiteness increase in connection with a known optical brightener for polyester fibers and polyester-containing textile material include some stilbene compounds, for example unsubstituted stilbene or stilbene substituted by cyan or C1-C9alkoxycarbonyl groups, and some nitrogen and Oxygen-containing heterocyclic compounds, for example 2- (diphenylyl) -5- (4-tert-butylphenyl) -1,3,4-oxidiazole, 2- (diphenylyl) benzoxazole and 2- (p-tolyl) -5-tert-butyl-benzoxazole.
- the preferred booster used is 4,4 ⁇ -bis (cyan) -stilbene or 4,4 ⁇ -bis (ethoxycarbonyl) -stilbene, which can be recrystallized beforehand from a solvent, for example dimethylformamide.
- a number of compounds known for brightening polyester-containing textile material can be used as optical brighteners for the process according to the invention, for example 2,4-dimethoxy-6- (1-pyrenyl) -1,3,5-triazine, N-methyl-4, 5-diethoxynaphthalimide, 2- (4-chlorostyryl-2-cyanophenyl) naphthotriazole and 1,4-bis (benzoxazol-2-yl) naphthalene.
- optical brightener and booster for the method according to the invention, it was found that there are specific combinations in which the booster has a particularly activating effect on the brightener. While a booster together with a certain brightener can cause an additional whiteness increase of up to 15 whiteness units, the same booster has little or no influence on another brightener as expected to brighten it.
- the present invention also relates to means for optically brightening polyester-containing textile material which contain an optical brightener and a compound which is fluorescent in its absorption region as a booster.
- compositions according to the invention can be prepared by dispersing the individual compounds in a liquid medium, for example water, and then by combining the dispersions. But you can also disperse a mixture of the individual compounds in bulk, which is done in a conventional manner in ball mills, bead mills or the like.
- the agents according to the invention can be applied to the textile material containing polyester by known methods, for example by the exhaust process at 90 to 140 ° C or by the padding thermal process at 160 to 220 ° C.
- the application is advantageously carried out in an aqueous medium in which the compounds are in finely divided form as suspensions, so-called microdispersions, or, if appropriate, solutions.
- dispersants, stabilizers, wetting agents and other auxiliaries can be added during application.
- a polyester fabric (Terylene type 540) is padded at room temperature with an aqueous liquor containing 0.5 g / l of the optical brightener of the formula 1 g / l of the compound of the formula and 1 g / l Invadin JFC 200%.
- the squeezing effect is 70%.
- the mixture is then dried at a temperature of 70 ° C. for 30 minutes and then heat-set at 200 ° C. for 30 seconds.
- the polyester fabric treated in this way has a lightening effect which is 8 whiteness units above the whiteness if no compound of the formula 2 is used.
- optical brightener of the formula is used according to the same procedure as in Example 1 and the compound of formula 3 previously recrystallized from dimethylformamide gives an increase in whiteness compared to the use of the compound of formula 4 alone of 9 whiteness units.
- optical brightener of the formula is used according to the same procedure as in Example 1 and the compound of formula 3 previously recrystallized from dimethylformamide gives a whiteness increase compared to the use of formula 5 alone of 11 whiteness units.
- optical brightener of the formula is used according to the same procedure as in Example 1 and the compound of formula 3 previously recrystallized from dimethylformamide gives a whiteness increase compared to the use of the brightener of formula 6 alone of over 20 whiteness units.
