DE3111149A1 - ACTIVE SUBSTANCE AND METHOD FOR REDUCING THE GRAYING OF TEXTILES AT THE LAUNDRY OR CHEMICAL CLEANING - Google Patents

Description

Active ingredient and process to reduce the graying of textiles during washing "or dry cleaning

The invention relates to a drug group for reduction the graying of textiles during wet washing b ;; w. Without eye cleaning as an addition to conventional detergents or chemical cleaning agents.

Graying occurs as a quality-reducing side effect both in the laundry and in the dry cleaning of Textiles when the dirt content of the washing liquor or the dry cleaning bath increases and / or the concentration of the detergent or cleaning booster used for a sufficient Dirt carry vorrriui-ioii too low isu; even with more abundant The use of these gowns will turn gray.

According to the invention it has been found that the graying of the textiles Both the laundry and the chemical cleaning can be significantly reduced if the conventional detergents or Eeinxgungshöhkern (a selection is presented in the working examples) 3-30% by weight of the triammonium salt Citric acid or carbally acid (1.2.3-propane tricarboxylic acid) with one of the salt formulas below tertiary amines is added:

In the formulas mean:

A is a hydroxyl group (citric acid.) Or hydrogen (tricarballyl acid),

E ₁ methyl,

Ep is a fatty alkyl having 8-18 carbon atoms, Ei is a polyoxethylene radical of the formula - (CIi ₀ -GH ₀ -O-) H, where η is a number from 1 to 9, and

Ei is an alkyl polyethoxylate radical of the formula

-CH ₂ -O -) ^, where

Έί-, a fatty alkyl with 10-18 carbon atoms and η is a number from 1 to 9 which is (essentially) equivalent to the number η for IcJL.

The active ingredients according to the invention arise in a smooth reaction: when reacting the tri-basic acid with an Ileboss of each temporary tertiary amine in water.

Dry cleaning is a particularly effective reduction the graying achieved when the Triammoniumsalζ off Cocosalkyldimethylamine or from a hydroxyalkylamine of

example 1

White test cloth from Krefeld Laundry Research (WFK) was dissolved in samples of the same dry cleaning soiled use Bales for 15 min at 30 ⁰ C treated, after addition of

a) 5 g / l of a commercial anionic i-.einigungsverstärkers, consisting essentially of about 20 wt.% I aliumdodecylbemiolsulfonat, 30 wt.% lonylphenylethoxyiaten,

The degree of whiteness was then decreased for the test rev / ebe in> o from the initial value determined by electrophotometric measurement.

It surrendered for treatment after

a) 12.7 % graying of the test fabric,

b) 4.7 % graying of the test fabric and

c) 7 * 1 % graying of the test fabric.

Example 2

The procedure was as in Example 1. However, it was used dirty Dry cleaning bath one case

a) 5 ε / l of a commercially available, cation-active no-degradation enhancer, essentially consisting of et; ^ a 20% by weight of dicocosalkydimethylammonium chloride, 30% by weight of nonylphenyl ethoxylates,

Example 3

a) WTK-test fabrics were a batch died soiled work clothes added, there was a mol with a nonionic detergent which tr.it essentially of nonyl phenyl ethoxylate 12 ethylene, washed at 60 ⁰ C.

b) In a comparable wash of work clothes soiled in the same way and the wash liquor also contained WFK test fabrics Detergent according to a) additionally 15 wt. #> the amount of detergent on a graying reducer according to the invention, namely the triammonium citrate of the following tertiary amine:

where E is a fatty alkyl with 10 or 12 carbon atoms means.

It surrendered after washing

a) 4.3 ° / o of the test fabric graying and aach

b) 2.7% graying of the test fabric.

where R is a fatty alkyl having 14 or 16 carbon atoms.

It surrendered to the laundry

a) 2.1% graying of the Wi ¹ K test fabric and gradually

b) 1.7% graying of the WFK test fabric.

As the examples clearly show, the active ingredients according to the invention require an addition to conventional cleaning boosters with dry cleaning or as an additive to conventional detergents for wet washing, a considerable reduction in graying of textiles in comparison with the conventional values for graying. When using the graying reducer According to the invention, the previous degree of graying is reduced to 40-60%, provided that the Kischungsverhälnisse given in the examples chooses; in the case of other cleaning enhancers or detergents or other types of soiling, 3-30% by weight Addition of one of the active ingredients according to the invention to the conventional one Gowns must be sufficient or appropriate for a satisfactory reduction in graying.

Instead of being used as a salt, the components tricarboxylic acid and tertiary Atnin the graying reducer g; em according to the invention too added separately to the cleaning booster or the dry cleaning bath or the detergent or the washing liquor will.
