Definitions

  • the agents can contain graying inhibitors which keep the dirt detached from the fibers suspended in the liquor and thus prevent graying.
  • Cellulose ethers such as carboxymethyl cellulose, methyl cellulose, hydroxyalkyl celluloses and mixed ethers such as methyl hydroxyethyl cellulose are suitable. Methyl hydroxypropyl cellulose and methyl carboxymethyl cellulose. Mixtures of various cellulose ethers are also suitable, in particular mixtures of carboxymethyl cellulose and methyl cellulose or methyl hydroxyethyl cellulose. Their proportion is preferably 0.3 to 3% by weight.
  • the outlet nozzles arranged on the hollow shaft are advantageously extended to such an extent that they protrude into the powder stream. Due to the increased centrifugal forces, this enables compressed air-free conveying and atomization of the nonionic surfactant, which is then distributed and absorbed by the powder stream.
  • the number of feeds is expediently from 1 to 10, with an arrangement in the cylinder wall preferably being arranged laterally in the region of the ascending powder stream. If several feeders are arranged one behind the other, the last should be installed so far in front of the outlet opening that the emerging nonionic surfactant is still homogeneously distributed.
  • a total of 4 feeds (diameter approx. 10 mm) were arranged at a mutual distance of 10 cm in the first third of the mixing section laterally in the area of the rising powder flow, via which the nonionic component (b) was fed into the mixer.
  • the size of the outflow opening at the outlet end of the mixer could be regulated by means of a flap. In the following Examples 1 to 4, this flap was set so that a slight back pressure and thus a uniform filling state formed in the mixer during continuous operation.
  • the rotational speed was approximately 1,500 rpm and the average residence time was 20 to 60 seconds, on average 30 to 40 seconds.
  • the mixer was charged with spray-dried powder, which was transported via a pneumatic conveyor system after leaving the tower discharge has been and had a temperature of about 30 ° C or after an intermediate storage of 20 to 25 ° C.
  • the powders proved to be easy to pour, non-dusting and dissolved quickly when littered in household washing machines, without lumps and without residue.
  • a vibration test that simulated mechanical stress during the transport of the packs, the powder components did not separate.
