Definitions

  • the invention relates to a process for continuous wet processing of textile materials, such as in particular used for bleaching or dyeing a web of woven or non-woven textile material, as well as to a diffusion station for a coloring matter in a textile material allowing in particular the implementation of said process.
  • the invention will find its application in particular in the field of wet processing facilities such as for bleaching and dyeing a web continuously.
  • the material to be treated is placed in an apparatus which is successively filled with liquids which may for example be a dye solution, a fixing liquid, a rinsing liquid and sometimes even with steam.
  • liquids which may for example be a dye solution, a fixing liquid, a rinsing liquid and sometimes even with steam.
  • the second type of treatment said to be continuous, is less developed than the other because it requires a more elaborate and cumbersome treatment installation.
  • the advantage of this treatment is that it makes it possible to work much faster and to increase the production of treated material.
  • the continuous processing installations consist of a succession of work stations each assigned to a well-defined stage and a continuous web of textile material is run through this installation according to a well-defined treatment path in the installation.
  • the continuous web undergoes the various stages successively between the entry and the exit of the installation.
  • a first category of dyes is generally known under the name "tank type" which is in an insoluble pigment form.
  • the textile material is impregnated with the dye by padding followed by diffusion in the fiber by an air course of the sheet which improves the appearance and the quality of the dye. .
  • the coloring matter is fixed by chemical padding and by spraying.
  • it is important to avoid another passage to air because there is a risk of modification of the structure of the dye, which can cause the shade to change and influence the solidity of the dye.
  • this dye is oxidized, rinsed and dried.
  • a second type of dye is known by the name "hydrone".
  • the textile material is impregnated with the dye by padding, but the dye is in the reduced state with sodium hydroxide in a bath.
  • the passage to air to diffuse the coloring matter in the textile fiber is to be avoided in order to prevent the premature oxidation of the reduced dye, which would give a duller shade to the dye.
  • the dye is fixed by vaporization, which will advantageously be followed by a passage in air because an oxidation in air before rinsing will make it possible to obtain a higher yield of the dye.
  • this dye is oxidized, rinsed and dried.
  • continuous processing installations which successively have a textile material supply station in ply, followed by a padding impregnation station of the coloring matter, followed by a station for diffusing the coloring matter by passing it through the air, followed by a station for dissolving the dye by impregnating chemicals, followed by a spray-type fixing station, followed by a chemical acid treatment station, followed by a second station for the diffusion and development of the dye by passage through air, followed by a washing and rinsing station, followed by a drying station, followed by '' a station for storing the material thus treated continuously.
  • stations for spreading and developing the coloring matter in the known textile material generally constituted by a set of fixed detour rollers traversed by the sheet in zigzag treatment, we work in all or nothing and we do not control not entirely the diffusion time of the coloring matter depending on the textile material and the dyes applied.
  • the object of the present invention is to provide a process for the continuous wet processing of textile materials, such as in particular used for bleaching or dyeing a web of woven or nonwoven textile material, which makes it possible to control the phases of diffusion and development of the treatment material in the textile material as a function of the material to be treated and the treatment materials applied while avoiding the manual manipulations of change of course mentioned above between two different types of consecutive treatment.
