There is already a method of treating the groups on phosphorus can

Fibers, yarns, fabrics, knitted fabrics or textiles - for their part, may be further substituted,
goods made of natural or synthetic fibers The new activators are depending on their

substances with peroxyde-containing aqueous solution composition solid or liquid and light or solutions or suspensions in the presence of a 5 sparingly soluble in water.

Activating agent known, which can thereby be As in the process of the main patent

is characterized by the fact that the new activators are used as activators in relatively small amounts of a reaction product of an ester of phosphorus. Usually acid comes with an acylating agent used. The treatment temperatures active with 0.1 to 1 mole of the activator per mole are between 60 10 oxygen in the bleaching bottle.
and 8O ⁰ C. Den inorganic peroxide compounds

There has now been a process for washing and / and activators containing bleaching liquors or bleaching fibers, yarns, fabrics, the usual stabilizers, buffer substances, wetting agents, knitted fabrics or textile goods made of 'natural or detergent substances, fiber protection agents and / or synthetic fibers with inorganic per - 15 optical brighteners can be added. The bleaching oxides containing aqueous solutions or suspensions is best carried out in weakly alkaline, neutral sions in the presence of reaction products from or weakly acidic medium.
Esters of an oxygen acid of phosphorus and finally it has been found that mixtures of the

Acylating agents found as activating agents, new activators with inorganic peroxidic which is characterized in that active compounds are good at ordinary temperatures a reaction product of an ester can be stored, even in the presence of the usual a phosphonic acid or a phosphinic acid with other detergent ingredients. One can an acylating agent used, the Ver therefore the peroxidic compounds and the optionally drive in the presence of stabilizers in the form of solid detergents versatoren, Buffer substances, wetting agents, active detergents, which only apply in water before bleaching Substances, fiber protection agents and / or optical components need to be dissolved or suspended when healing is performed. they are solid activators.

The addition of these activators, which after. ·,,

Knowledge of the inventors also new compounds Example 1

allows good bleaching effects to be achieved 30 A boiled with red wine and then dried again at temperatures of about 30 to 60 C, net cellulose tissue showed in Elrepho whiteness for a while about the same bleaching effect without knife against white standard 656 with filter 6 activator addition only occurs at 70 to 100 ° C. a whiteness of 31%.

As activators, for example, the very heavily soiled tissue is used

bonds of the following formulas into consideration: 35 three times for 15 minutes at 60 ° C in a Launder

O O Ometer treated with a liquor that per liter

contained the following substances:

- * C ₂ H ₅ -OPOC - /> _lv 25O g alkyl sulfate,

0.625 g Na pyrophosphate,

⁴ 0.625 g sodium tripolyphosphate,
0.350 g dry water glass,
0.700 g sodium perborate,

1,000 g of ethyl benzoyl benzene phosphonate

45 and a pH between 7 and 8. After washing, the fabric had a degree of whiteness of 64.3%.

A comparatively with the same bath under the same conditions, only without the addition of

50 Benzoyl-benzenephosphonic acid ethyl ester, washed cellulose tissue had a whiteness of only 44.5%.

Example 2

55 In the same manner as in Example 1, a cotton fabric with the strong Rotweinanschmutzung three times for 15 minutes at 6O ⁰ C was washed with a liquor containing per liter the following substances:

1,250 g alkyl sulfate,

0.625 g Na pyrophosphate,

0.625 g sodium tripolyphosphate,

0.350 g dry water glass,

0.700 g sodium perborate,

1,000 g O-Benzoyl-benzenephosphonic acid

⁵ phenyl ester

and had a pH of 8.3 to 6.5. Furthermore, the described red wine was used for comparison

H.-O-P-O-C

Soiling with the bath listed here, but without phenyl O-benzoyl-benzene-phosphonate washed under otherwise identical conditions. The following degrees of whiteness were measured:

Soiled fabric 26%

Tissue washed with activator 48% Tissue washed without activator 34%

Example 3

^v IC

In the same way as in Example 1, a cellulose fabric with the strong red wine soiling was ^{washed three times for 15 minutes at 60 °} C. with a liquor which contained the following components per liter:

1,250 g of alkyl sulfate, ' ⁵

0.625 g Na pyrophosphate,

0.625 g sodium tripolyphosphate,

0.350 g dry water glass,

0.700 g sodium perborate,

1,000 g of O-benzoyl-diphenylphosphinic acid.

A comparison was also made with the same bath, but without the addition of O-benzoyl-diphenylphosphinic acid washed.

Degree of whiteness before washing 28.0%

Degree of whiteness after washing without

Activator 38.6%

Whiteness after washing

Lightening: 12.6 degrees of whiteness

Example 4

Instead of 1.00 g of O-benzoyl-diphenylphosphinic acid 1.00 g of O-benzoyl-din-butyl-phosphinic acid was added to the washing bath added.

Degree of whiteness before washing 28.0%

Degree of whiteness after washing without

Activator 38.6%

Whiteness after washing

Activator 57.8%

Lightening: 19.2 degrees of whiteness

Claims (1)

Claim: Process for washing and / or bleaching fibers, yarns, woven, knitted or knitted fabrics Textile goods made from natural or synthetic fibers containing inorganic peroxides aqueous solutions or suspensions in the presence of reaction products Esters of an oxygen acid of phosphorus and acylating agents as activating agents, characterized in that as Activating agent a reaction product of an ester of a phosphonic acid or a phosphinic acid used with an acylating agent, the process optionally in the presence of stabilizers, buffer substances, wetting agents, detergent substances, fiber protection agents and / or optical brighteners.
