Description

1 2502143

  The invention relates to a group of active substances

  to reduce the fading of the hue of

  textiles during wet scrubbing or chemical cleaning

  to be added to cleaning detergents or reinforcers

  classics. The dulling of the hue occurs as a phenomenon accompanying the decrease in quality both during washing and during chemical cleaning of textile materials, when the dirt content of the washing bath

  or the chemical cleaning bath increases and / or the concentration

  detergent or cleaning intensifier used is

  too weak to obtain a power to displace

  sufficient sures; even with sufficient use of these

  agents, dulling of the hue is observed.

  In accordance with the invention, it has been found that the

  The dyeing of textile materials in both washing and chemical cleaning can be considerably reduced when added to conventional cleaning agents or detergents (a choice is proposed in the examples

  following) from 3 to 30% by weight of a triammonium salt of the

  citric acid or carballylic acid (1,2,3-propa-

  netricarboxylic) with one of the tertiary amines is deduced

  whiteness of the reference tissues in% of the initial value

  by an electrophotometric measurement.

  For the treatment according to a) 12.7% tarnishing of the test fabric according to b) was obtained: 4.7% tarnishing of the test fabric and according to

  c): 7.1% tarnishing of the test fabric.

  wherein R is a fatty alkyl group

  having 14 or 16 carbon atoms.

  For this wash, 2.1% fabric tarnishing / WFK and (b) 1.7% tarnishing of the test fabric were observed according to test a). As the examples clearly show, the

  active substances according to the invention used as additives

  to the usual cleaning reinforcers for the net-

  chemical cleaning or as additives to the usual detergents for

  wet cleaning results in a reduction in

  the tarnishing of the hue of textile materials

  compared to conventional tarnishing values. In

  using the agent reducing the dulling of the hue sec-

  According to the invention, the degree of tarnishing observed until

  this is reduced by 40 to 60%, inasmuch as the mixture compositions indicated in the examples are selected; for other cleaning enhancers or detergents or other soils, an addition of 3 to 30% by weight of

  active substances according to the invention to a conventional agent.

  that can be sufficient or incorporated to obtain a

  satisfactory reduction of the dullness of the hue.

  Instead of salt, it is also possible to add

  by the constituents tricarboxylic acid and amine

  tertiary agent reducing dullness

  cleaning agent or chemical cleaning bath, or

detergent or washing bath.
