The present invention relates to a method for producing non-scattering, abrasion-resistant, water-soluble dye particles. It is known to produce water-soluble dyes, especially reactive dyes, from their concentrated solutions in a spray chamber. The dye powders produced in this case are very fine and therefore have a correspondingly low bulk density and are highly susceptible to scattering. Fine particles are desirable because of the high dissolution rates and thereby the work speeds they enable, but they are non-splattered or shattered to avoid pain and harm to workers and contamination of the manufacturing room and product. There is a need for dyes and dye preparations that are difficult to dye. It is known to provide additional anti-scattering treatment by incorporating anti-scattering agents such as oils or various other additives or combinations thereof into the dye powder. Such additional anti-scattering treatments by incorporating anti-scattering agents are on the one hand very expensive and on the other hand create troublesome new problems in the use of dyes, depending on what substances are used as anti-scattering agents. obtain. Also, this method does not take into account the problem of low bulk density. It is therefore an object of the present invention to develop a method for producing non-scattering, abrasion-resistant dye particles. This problem is solved by spraying an aqueous dye solution into a fluidized bed of dye particles created by a gas stream capable of absorbing moisture. The dye solution can be sprayed into the fluidized bed from above, from below and/or from the side. This solution may contain a bulking agent (Stellmite). The term aqueous dye solution refers to an aqueous solution containing dissolved solids from 0% to saturation. Solids include dyes, fillers, additives (eg surfactants, binders, etc.) and compositions thereof. Salt is particularly preferred as a bulking agent. The dye particles can be classified and the undersized particles as well as the crushed oversized particles can be returned to the fluidized bed. Additionally, steam may be sprayed into the fluidized bed. Although not necessary, solvents such as Manutex (trademark)
Binders such as Manutex or Tylos may also be added. When dye solutions or prepared dye solutions are subjected to preconcentration in suitable equipment, the residence time of these solutions in the fluidized bed and the possible temperature loads associated therewith can be reduced while saving energy. can. The arrangement of the nozzle - which allows spraying from above, from below and/or from the side - has no essential influence on the granulation process. Arrangements that allow spraying from above onto a fluidized bed are most advantageous. The method can be carried out discontinuously or continuously. If carried out continuously, it is advantageous to guide the product feed stream of dye powder or granules or a mixture of granules and powder by a conical spray of dye solution. Agglomerates are broken up in a known manner by means of suitable devices, such as rotary valves. The dye dust entrained by the exhaust air is captured by a self-refining drying filter and returned to the fluidized bed either directly or through feed means. The invention will be explained in more detail by the following examples (tables). The experimental setup is exemplarily shown in the figure. The fluidized bed apparatus consists of a housing 1 for a fluidizing chamber. This fluidized bed apparatus has a metering supply means 5
In addition, it has at least one spray nozzle 2. Hot flowing air is passed from the gas inlet 4 to the perforated plate 6.
and exits the fluidized bed apparatus at 7 containing moisture. A discharge connection 8 for the desired product opens directly above the perforated plate 6 into the flow chamber. This connecting pipe 8 is equipped with a rotary valve 3.
