Embodiment 1
[0137] Embodiment 1: synthesis
[0138] 1.1: Preparation of amino-substituted siloxanes according to DE 102011110100 A1
[0139] The preparation of the amino-substituted siloxanes is carried out according to DE 102011110100. The amount of each raw material used is directly derived from the stoichiometry of the polymer composition. The weight % values are all based on the sum of all starting masses.
[0140] In a four-necked flask equipped with a stirrer, internal thermometer and distillation bridge, with 29 Dihydroxy-functional polydimethylsiloxane of known chain length by Si NMR, hexamethyldisilazane and 0.07 wt% of 85 wt% strength phosphoric acid were heated at 85°C with stirring and stirred at this temperature for 30 minute. Aminopropylmethyldiethoxysilane and an additional 0.07% by weight of 85% strength by weight phosphoric acid were added and the mixture was stirred at 85° C. at 14 to 20 mbar for one hour and also at 120° C. for a further 2 hours. Filtration thr...
Embodiment 2
[0150] Example 2: Compositions and formulations
[0151] A typical composition of the present invention contains 20% by weight of crosslinked aminosilicone, 15% by weight of diethylene glycol monobutyl ether (BDG), 0.3% by weight of organic acid and 64.7% by weight of water.
[0152] Compositions were prepared by stirring briefly at room temperature. Stirring was continued until the mixture was a homogeneous single phase mixture, ie no second phase was visible. Typically, the formulation is homogeneous within 10 minutes of stirring. Depending on the viscosity of the crosslinked aminosiloxane, it is sufficient to use a KPG stirrer, or a magnetic stirrer. The compositions of the present invention are clear, transparent or milky.
[0153] It remained homogeneous after turning off the stirrer, did not phase separate even when stored at 22°C for two weeks, and did not turn yellow.
[0154] In such formulations, non-inventive aminosilicones not hydrophilized by crosslinking exhi...

[0162] Embodiment 3: application test
[0163] Pretreatment of test fabrics:
[0164] Pre-treat standard fabrics first. Wash once with 32g of test detergent, and then wash again without using test detergent.
[0165] The washing operation was carried out in a commercial Miele Novotronic W 918 washing machine with color wash, without prewash at 40°C, using wfk standard laundry detergent IECA-Base and 3 kg of cotton ballast fabric. Finally, the treated fabric was dried at room temperature for 12 hours. The test fabrics were cut into sheets measuring 30 x 40 cm.
[0166] A1:
[0167] For the tests, a basis weight of 170 g / M from wfk Testgewebe GmbH (Christenfeld 10 41379 Brüggen) was used 2 Wfk code 30A polyester fabric with 1 / 1 weave, and three pieces of dyed taffeta with different basis weights (woven polyester product with 1 / 1 weave), at 25°C Soak in a dyebath of 0.08% (by active substance) at a dyebath to product ratio of 12 to 1 for 20 minutes with gentle mixing, then ...
