Definitions

  • the present invention relates to a composition for reducing crease formation on textiles, which comprises a mixture of at least one aminoalkylsiloxane and at least one higher alkyl-modified amido aminosiloxane modified by hydroxycarboxylic acids and/or mono- and/or disaccharides having in each case at least two hydroxyl groups, and to the use of this composition for the treatment of textiles.
  • Greases and wrinkles in textiles are caused by folding and creasing the textiles as a result of the action of external forces, especially by wearing and by washing the textiles, wherein the outward facing part of the textile is strained and simultaneously the inward facing part of the textile is exposed to a pressure. At the molecular level this can especially lead to the formation of hydrogen bonds that following a decrease in the action of the force can at least partially stop the state of deformation. This problem arises principally with cotton and the hydrogen bonds that are present here between cellulose molecules.
  • compositions for reducing crease formation in textiles, which involve a starch-containing liquid and comprise aminosilicones.

  • plastic peg not more than 5 mm material may be gripped.
  • the crease is produced by the load of a flat weighted block having a defined weight of 19.63 N (2 kg) for a period of 5 minutes.
  • the creased material sample is carefully placed into the clamp. After fixing it in position, the material is also clamped into the upper clamping jaw. The vertical position serves as the reference point. When the creased material touches this point by turning the angle wheel, the angle is read on the angle wheel.
  • the measurement is made 5 minutes after removing the weight from the wheel or after the crease formation.
  • CRA crease recovery angle difference
  • the active substance was dissolved in a concentration of 1% active substance in a 3% ethanol solution.
  • the treatment was carried out as described in example 1.
  • each of the active substances was dissolved in a concentration of 0.5% active substance (1% total concentration of active substances) in a 3% ethanol solution.
  • the treatment was carried out as described in example 1.
  • the CRA of the commercial agent and the CRA of water/ethanol (3%) served as the reference; CRA difference: 4°
  • the active substances were dissolved in a concentration of 0.4% and 0.6% active substance (1% total concentration of active substances) in a 3% ethanol solution.
  • the treatment was carried out as described in example 1.
  • the CRA of the commercial agent and the CRA of water/ethanol (3%) served as the reference; CRA difference: 6°
  • Each underlined product refers to the corresponding concentration.
  • the active substances were dissolved in a concentration of 0.3% and 0.7% active substance (1% total concentration of active substances) in a 3% ethanol solution.
  • the treatment was carried out as described in example 1.
  • the CRA of the commercial agent and the CRA of water/ethanol (3%) served as the reference; CRA difference: 5°
  • Each underlined product refers to the corresponding concentration.
  • Bleached cotton cloth 1.1.10 (cotton) was used as the textile to be finished and was cut up into four 20 ⁇ 120 cm test samples per treatment. Creases were produced by washing the fabric samples in a domestic washing machine (with H 2 O only) and hanging them up in a climatized room for 24 hours. The horizontal test samples were sprayed as homogeneously as possible with 10 sprays of a commercial spray adaptor. The applied quantity corresponded to 0.16 g/cm 2 .
  • the temperature of the iron was set to step III.
  • the iron was weighed down with 2940 g of metal pellets. As the sliding surface of the iron was 23.5 cm long and had a maximum width of 12 cm, and the appliance, at the beginning and end of the measurement still laid on the fabric, there remained an approximately 20 cm long and 12 cm wide area on the fabric for the evaluation of the measurement data, for which a total of 400 measurement points (measurement values 300-700) from 1000 were used to calculate the mean value.
  • the tests were subdivided into two measurement series. For each formulation, 5 fabric strips were each ironed 4 times with the added weight of 2940 g. Each of the first ironing passages was not included in the subsequent evaluation. Before each measurement the iron was heated until the indicator light switched itself off. During the measurement run the plug was pulled out in order to avoid the resistance of the electrical cord. Prior to each new formulation, the iron was cleaned with a citric acid solution (3%), with ethanol and with distilled water. A strip of fabric of each formulation was used for a preliminary ironing pass in order to warm up the ironing overlay and to eliminate possible residues on the iron.
  • test samples were taken wet from the washing machine, hung up on a washstand and dried in a climatized room for 24 hours.
  • the creased test samples were visually evaluated and marked (1-5) against reference standards according to AATCC 124.
  • the reference standard marked 1 contains the most creases. 5 is completely free of creases.
  • the evaluation was carried out by 8 panellists. An average value was calculated from 8 different test values. Three test samples were treated with each product, such that in total 8 ⁇ 3 evaluation measurements were made per product.
  • the single treatment procedure consists of the following partial steps: Washing, drying, anti-crease test (AATCC 124), spraying and smoothing, drying and anti-crease test (AATCC 124).
  • the bleached cotton cloth 1.1.10 was used as the test sample.
  • the fabric samples were washed as follows in a domestic washing machine.
  • the wet washing was hung up on a washstand and dried in a climatized room for 24 hours.
  • the creased test samples were also evaluated prior to the spray treatment according to MTCC 124. 7 different panelists took part in the evaluation, such that the evaluation consisted of 7 ⁇ 3 notes per product.
  • the horizontal test samples were sprayed as homogeneously as possible with 5 sprays of a commercial spray adaptor of the old Perla spray bottle from a distance of 25 cm.
  • the applied quantity corresponded to 0.08 g/cm 2 .
  • the treated test sample was straightened out and smoothed by hand in each horizontal and vertical direction twice (see diagram).
  • test samples were hung up on a washstand to dry in a climatized room for 30 minutes.
  • test samples were visually evaluated and marked (1-5) against reference standards according to AATCC 124.
  • the reference standard marked 1 contains the most creases. 5 is completely free of creases. Marks of ⁇ 1 and marks to the first decimal place may also be given.
  • the evaluation was carried out by 7 panelists. An average value was calculated from 7 different test values. Three test samples were treated with each product, such that in total 7 ⁇ 3 evaluation measurements were made per product.
  • a commercial esterquat-containing rinse softener was used as the reference.
  • the formulations were used in a 17 l rinse softening liquor and then the anti-crease behavior of the fabrics was tested by means of the crease angle recovery tester.
