Definitions
- This brightener formulation can be used in particular for lightening paper.
- 10 g of the brightener of the formula (10) are mixed with 20 g of the acid ester of the formula (8) with the addition of 10 g of an adduct of 9 mol of ethylene oxide with nonylphenol, 16 g of tetramethylurea and 18 g of polyethylene glycol 300 in 26 g of deionized water at 70 solved up to 80 ° C.
- An aqueous brightener formulation which is stable against metal ions and metal catalysts is thus obtained.
- the amount of brightener is adjusted to the proportion of cotton.
- a polyamide 6.6 woven jersey is introduced in a 1:20 liquor ratio.
- the mixture is heated to 97 ° C. in the course of 30 minutes, kept at this temperature for 30 minutes and then cooled to 40 ° C. within 15 minutes.
- the treated fabric is rinsed in running cold water for 30 seconds and then dried with an iron at 180 ° C.
- the fabric treated in this way has a strong lightening effect. Similar effects are also achieved if metal salt catalysts are present in the fleet.
- the fabric treated in this way has a strong lightening effect. If, instead of the brightener formulation according to Example 1, an equivalent amount of a brightener formulation according to Examples 2 to 9 and 12 to 26 is used in the above regulation, similarly brightened polyamide 6.6 fabric is obtained.
- bleached cellulose (10% suspension) are mixed in a metal beaker with 99 ml water and 1 ml aluminum sulfate solution 10%. After 2 minutes 7.5 ml of a 10% filler slurry (kaolin), after 10 minutes 0.036 g of a formulation obtained according to Examples 10, 11, 27 or 27a are added. At intervals of a further 2 minutes, 2 ml of 5% resin glue solution and 1.5 ml of 10% aluminum sulfate solution are added. It is then made up to 500 ml with water, the suspension is placed in a mixing beaker, made up to 1000 ml with water and mixed for 2 seconds. The mass is processed into sheets of paper, including pressing and drying, in a known manner.
- the paper obtained in this way has a strong brightening effect of good lightfastness in all four cases.
- bleached cellulose (10% suspension) 50 g bleached cellulose (10% suspension) are mixed in a metal beaker with 99 ml water and 1 ml aluminum sulfate solution 10%. After 2 minutes 7.5 ml of a 10% filler slurry (kaolin), after 10 minutes 0.1 g of the formulation obtained according to Example 1 are added. At intervals of every further 2 minutes, 2 ml of 5% resin glue solution and 1.5 ml of 10% aluminum sulfate solution are added. It is then made up to 500 ml with water, the suspension is placed in a mixing beaker, made up to 1000 ml with water and mixed for 2 seconds. The processing of the mass into sheets of paper, including pressing and drying, is carried out in a known manner.
- the paper thus obtained has a strong lightening effect with good light fastness.
