Definitions

  • the invention relates to a method for improving the color fastness of textile materials made from plastics.
  • Synthetic materials can only be dyed inadequately using conventional dyeing processes. Difficulties arise with polyesters (PES), polyamides (PA), polyurethanes (PU) and other plastics, in particular when the textile material consists of a mixture of different plastics, for example PA and PES. Additional problems arise when it comes to microfibers. We are therefore looking for options which result in good coloring of the individual plastics or their mixtures and which also have high fastness to use, such as fastness to washing and light.
  • PET polyesters
  • PA polyamides
  • PU polyurethanes
  • the object of the invention is to provide a process which, with reduced amounts of alkali, in particular in the case of materials consisting of PES and / or PA, leads to high color fastnesses - in particular light fastness - and only slightly reduces the tensile strengths.
  • the object is achieved by a generic method in which the material is subjected to at least one additional heat treatment after it has been colored.
  • the process is preferably carried out in that the heat treatment is carried out in a dry atmosphere for a period of 0.1 s to 60 min at temperatures between 50 ° C. and 300 ° C.
  • the method can be carried out in such a way that the heat treatment is carried out in the presence of moisture for 0.1 s to 60 min, temperatures between 50 ° C. and 300 ° C.
  • the heat treatment is carried out for a period of 0.1 s to 2 min at temperatures between 100 and 250 ° C.
  • the additional heat treatment is preferably carried out during treatment steps such as e.g. embossing, equipping or assembling the material.
  • the additional heat treatment is preferably applied to a material that contains microfibers or that consists entirely of microfibers.
  • the additional heat treatment is applied to a material that consists of a nonwoven, in particular of a material that consists of PA and / or a mixture of PA and PES fibers and / or microfibers.
  • the color fastness in particular the light fastness of the dyeings, as the following examples show, is significantly increased.
  • only a comparatively small reduction in the tensile strength occurs when dyeing samples containing polyester fiber.
  • Microfibers or filaments in the sense of this application are understood to mean those with a titer of ⁇ 1 dtex.
  • a microfilament nonwoven fabric consisting of 35% by weight of PA and 65% by weight of PES, is dyed in a one-step exhaust process with the vat dye shown in Table 1 (dye use 3% based on the fiber weight).
  • the vat dye is mixed with 1 g / l of the dispersant DekokDSN and 0.5 g / l of the complexing agent Trilon®TA dispersed. The liquor ratio is 1:20.
  • the mixture is first heated to 80 ° C., then pigmented at this temperature for 20 minutes.
  • the vaulting is carried out with 20 ml / l 32% by weight NaOH and 8 g / l hydrosulfite.
  • a microfilament nonwoven fabric consisting of 35% by weight of PA and 65% by weight of PES is dyed in a one-step exhaust process with a mixture of the disperse and vat dyes given in Table 2. Both the disperse dye and the vat dye are dispersed together with 1 g / l of the dispersant Dekol®SN and 0.5 g / l of the complexing agent Trilon®TA, and a pH of 4.5 to 5 is set with acetic acid. The liquor ratio is 1:20. The dyeing takes place at 130 ° C for 45 min.
  • the mixture is then cooled to 80 ° C., cooled with 12 ml / l of 32% by weight NaOH and 6 g / l of hydrosulfite with the addition of 20 g / l of Glauber's salt. After vatting, dyeing is continued for 30 min at 80 ° C and cooled to 50 ° C and rinsed.
  • the oxidation is carried out at a liquor ratio of 1:20 with 5 ml / l hydrogen peroxide (30% by weight). Carried out for 15 min at 60 ° C and soaped at 40 ° C with 2 g / l soda and 1 g / l Kieralon®B. After drying, heat treatment is carried out at 150 ° C for 1 min.
  • a printing paste that contains 800 g / l of a stock paste - consisting of 600 g / l starch ether thickener, 50 g / l Glyezin®A, 100 g / l potash and 100 g / l Rongalit C - 20 g / l of the vat dye lndanthren® Yellow T-5GF and 180 g / l of water is knife-coated onto a microfilament nonwoven fabric consisting of 35% by weight of PA and 65% by weight of PES, dried at 98 ° C, fixed for 10 minutes at 102 ° C with saturated steam , The dyeing is then rinsed and oxidized with 5 ml / l of 30% strength by weight hydrogen peroxide for 15 min at 60 ° C. and soaped at 70 ° C. with 2 g / l of soda and 1 g / l of Kieralon®B. After drying, a calender is embossed at 240 ° C
  • the oxidation is carried out at a liquor ratio of 1:20 with 10 ml / l hydrogen peroxide 50% by weight.
  • a microfilament nonwoven consisting of 35% by weight of PA and 65% by weight of PES, is mixed with 6.6% (based on the fiber weight) of vat dye Cl.
  • Vat Black 27 colored at a fleet ratio of 1:57.
  • the mixture is first heated to 95 ° C., then pigmented for 20 minutes at this temperature.
  • the vatting is carried out with 25 ml / l of 32% by weight NaOH and 9 g / l of hydrosulfite.
  • Example 3 of the document EP 0772709 B1 the microfilament nonwoven fabric consisting of 35% by weight PA and 65% by weight PES specified in Example 5 is dyed with Cl Vat Black 27.
  • a sample of nonwoven (1.5 g) was run for 45 minutes at 95 ° C. in an aqueous solution of Cl Vat Black 27 (2 ml of a 5% aqueous solution), sodium hydroxide (10 ml of a 4M aqueous solution), Rongal HT (3rd g) and water (60 ml) treated.
  • the treated sample was rinsed, oxidized by treatment with 75 ml of an aqueous solution of potassium dichromate (1.5 g) and acetic acid (15 g) for 30 minutes at 65 ° C., rinsed and with 75 ml of an aqueous solution, the soap flakes (3 , 75 g) contains, washed in boiling water for 10 minutes.
  • the light fastness and tear strengths listed in Table 5 are achieved by the process described without heat aftertreatment. The results of the determined light fastness are shown in the following tables:
