Definitions

  • the invention is in the field of textile (pre-)treatment for dyeing applications and the respective compositions thereof as well as the use.
  • textiles are pre-treated to improve properties in these processes and further of the final textiles, as e.g. by scouring, bleaching, desizing, or mercerization.
  • the second important stage of the dyeing process that should be improved is the mercerization step during which the yarn is wetted in a highly concentrated caustic soda solution to modify the cotton structure. As a result, a deeper and more intense dyeing is obtained. Further advantageous, the afterwards applied dyes remain superficial, which is often required e.g. in sulfur dyes dyeing. To said superficial dyeing is often referred under the term "ring dyeing".
  • Mercerization is a textile process step that requires the use of highly concentrated Caustic soda solutions (usually > 20oBé, which is around 170 to 200 g/L). Hence, afterwards all this caustic soda must be washed requiring high amounts of water, and thereby generating a high amount of waste salts at the end of the whole dyeing process. Although parts of the washed caustic soda can be recovered and reused but since this caustic soda already has been in contact with yarn it comprises high amounts of chemical oxygen demands (COD) generated by the cotton impurities. Further, losses cannot be prevented and thus, recovering all the washed caustic soda is not feasible.
  • COD chemical oxygen demands
  • Textile material being only ring-dyed, so only on the surface of the fibers is dyed, offers several advantages as e.g. less dye consumption during dyeing, easier subsequent wash-off processes for color contrast and application of said less pollutant methodologies as lasers.
  • a few parameters can be controlled to obtain a ring dyeing to some extent, as e.g., low temperature, minimum contact time between the material to be dyed and the dyeing bath, using a "wet-on-wet" system preventing the dye solution from being absorbed directly into the fiber or decrease the squeezing pressure of dyeing boxes.
  • Polyelectrolytes are known in the prior art and have many applications, mostly related to modifying flow and stability properties of aqueous solutions and gels. For instance, they can be used to destabilize a colloidal suspension and to initiate flocculation (precipitation). Polyelectrolytes can be found used as thickeners, emulsifiers, conditioners, clarifying agents, and even drag reducers and can be used in water treatment and for oil recovery. Many soaps, shampoos, and cosmetics incorporate polyelectrolytes. Furthermore, they are added to many foods and to concrete mixtures (superplasticizer).
  • the problem to be solved by this application was to provide an improved process for the (pre-)treatment of textile material to be further processed, as for example being mercerized or dyed with e.g sulfur or vat dyes, especially indigo.
  • the inventors discovered that the (pre-)treatment of textile material with an aqueous composition according to the invention leads to advantageous properties of textile material in subsequent processing steps. For example, during mercerization less caustic soda is consumed, wash-out processes are simplified due to less alkalinity and thus less waste(water) is produced.
  • textile material pre-treated with the composition according to the invention show less shrinking under such harsh conditions as applied during mercerization for example.
  • Another particular advantage of the (pre-)treatment method according to the invention is that dyeing processes being subsequent to a (pre-)treatment according to the invention lead to more superficial dyeing, i.e. a ring-dyeing. Hence, less dye is consumed and further, more sustainable technologies can be used in after-treatments as for example laser technologies in wash-down processes.

  • textile includes but is not limited to everyday clothes, work clothes, safety cloths, household textiles such as carpets, bedding, curtains and the like; denim textile like trousers, e.g. jeans; jackets; skirts; dresses; t-shirts; or the like.
  • a mercerization bath containing 170 g/L of caustic soda, and another separated dyeing bath containing 150g/L of a Diresul Black RDT-K, a commercial Sulphur Black dye produced by Archroma, are also prepared, no additional caustic soda is added.
  • the process is done as follows:
  • Said ring-dyed yarn shows a dark black dyeing, at similar level when is compared with the result obtained using a conventional mercerization process, but much more superficial.
  • the amount of caustic soda consumed in the mercerization process was reduced by 65-75% (including recovery and depending on the washing efficiency).
  • Fig. 3 comprises a comparison with a non-mercerized textile material in which beside the less coloration due to the missing mercerization a comparable remaining length was measured as was measured for the sample pre-treated according to the invention and mercerized.
  • a cotton yarn will be dyed with a leucoindigo solution without a mercerization step.
  • two different samples were prepared, one according to the invention one according to processes known in the art.
  • the difference between the standard dyeing process and the process according to the invention is that in the standard process the crude cotton yarn will be contacted with the dye after being pre-scoured with water comprising only auxiliary agents in a wet-on-wet process.
  • the crude cotton yarn to be dyed in a process according to the invention has been soaked and pre-wetted with the polyelectrolyte solution prepared in Example 1. Both processes can therefore be considered wet-on-wet processes as well.
