Definitions

  • the invention relates to vat dyes dyed polyolefin fibers, their use for forming a textile and a process for producing such colored polyolefin dyed or dyed fabrics based on polyolefin fibers or textiles based on colored polyolefin fibers.
  • polypropylene fiber materials are becoming increasingly popular in various textile sectors (H.-J. Kosowski in Chemical Fibers Intern. 54 (2004), 272).
  • the biggest disadvantage of PP fiber and thus the biggest obstacle to a widespread introduction in the home textiles and clothing sector, is its very poor dyeability. This is due in part to the low affinity of most dyes for the completely nonpolar PP fiber surface, to the other diffuse dyes, primarily are disperse dyes, which are involved in the fiber according to the known Nernst release mechanism, due to the At very low temperatures, the high mobility of the macromolecule chains of the polypropylene prevails very easily again out of the fiber. This has bad wet fastness result.
  • the object of the invention is therefore to produce advantageous vat dyes dyed polyolefin fibers, which are characterized by excellent wash, rub and especially light-fastness values.
  • the dyeings are said to be comparable to vat dyeings on cellulose fibers in terms of hue and brilliance with the corresponding values of cellulosic fibers provided with vat dyeings.
  • a particularly suitable method for producing such dyed with vat dyes polyolefin fibers are proposed, the disadvantages of the previously established methods should be excluded, such as the lack of flexibility of spin dyeing, the negative effect on the fabric handle of a pigment dyeing and their poor rubbing fastness and also the poor washing and lightfastnesses of other colors on optionally modified polypropylene.
  • polyolefin fibers dyed with vat dyes which are characterized by a light fastness according to DIN EN ISO 105-B02 (at 50 0 C and 144 h exposure) of at least 5, a wash fastness to DIN EN ISO 105-C08C of at least 4 and a rubbing fastness according to DIN EN ISO 105-X12 dry of at least 3.
  • the light fastness of the polyolefin fibers according to the invention is at least about 6, whose wash fastness is at least 4 to 5 and / or whose rubbing fastness is at least about 4.
  • vat dyes which are particularly advantageous in the context of the invention.
  • a dyeing using indanthrene dyes are dyes that consist of two or more bridged anthraquinone molecules. These dyes prove to be extremely light, washing and weathering in the practice of the present invention.
  • a particularly suitable anthraquinone dye is indanthrene blue.
  • Indanthren brilliant green FFB Indanthren brilliant orange GK
  • Indanthren brilliant orange Indanthren brilliant pink R 5
  • Indanthren brilliant violet R Indanthren- dark blue BOA
  • Indanthren blue BC Indanthren blue RS ,
  • the inventively desired effects are achieved in particular when the polyolefin fibers have been subjected to a plasma treatment before their coloration with a vat dye.
  • the color yield during dyeing or printing compared with the non-plasma-treated polyolefin fiber increased by at least 55%, in the case of particularly suitable dyes by at least 120%.
  • the type of plasma treatment is not critical. It can take place in the atmospheric plasma (corona) or in the preferred case in the low-pressure plasma. In both cases, preferably oxygen or air plasmas are used.
  • the plasma treatment of the polyolefin materials is carried out until the polyolefin has an oxygen incorporation by ESCA (electron spectroscopy for chemical analysis) at least 10%, in particular at least 20%, in the surface layer, the layer thickness being 6 nm can be.
  • ESCA electron spectroscopy for chemical analysis
  • the invention thus relates to colored with vat dyes polyolefin fibers.
  • the idea according to the invention which is reflected above in the advantageous parameters, is not critically dependent on the type of polyolefin used in each case.
  • the vat dyeing can also be carried out in various ways, but in particular proceeding according to the padder-HT process, which is described, for example, in H.K. Rouette, "Encyclopaedia of Textile Finishing", Laumann-Verlag, Dülmen, 1995.
  • This means that a correspondingly concentrated dye liquor is applied to the material, for example by means of a padder, and the dyestuff is then subjected to the effect of, for example, high-temperature or saturated steam respective fiber is added.
  • the polyolefin is present in the form of a homo- or copolymer of ethylene, propylene and / or butylene, in particular in the form of a homopolymer of ethylene, propylene and / or butylene.
  • the vat dyed polyolefin fibers of the invention can be used with particular advantage to form a textile.
  • the nature of the textile is not relevant to achieving the desirable effects.
  • the polyolefin fibers according to the invention may be present in particular in a textile in the form of a woven, knitted fabric, fleece or fabric. It has proved to be expedient if such textiles contain not only the inventively colored polyolefin fibers incorporated. Rather, in individual cases, it is of particular value to additionally include other fibers, i. into the fabrics, knitted fabrics, nonwovens or fabrics. These may be in particular cellulose, polyester and / or polyamide fibers.
  • the cellulose fibers are of particular value, especially if they are in the form of cotton or viscose fibers. Nevertheless, the method is also suitable for fibers based on cellulose esters, in particular cellulose acetates of very different degrees of acetylation.
  • the object of the present invention was also to propose a suitable preparation process for the polyolefin fibers according to the invention which are dyed with vat dyes.
  • the invention also relates to an advantageous process for the production of colored polyolefin fibers or colored textiles based on the colored polyolefin fibers, as described extensively above, after which the polyolefin Polyolefin fiber-based fibers or textiles are subjected to a plasma treatment prior to dyeing with vat dyes.
  • the dyeing of the polyolefin fibers with vat dyes is preferably carried out by the pigment pad method.
  • the plasma treatment takes place in the form already treated above, ie an oxygen or air plasma treatment is carried out.
  • the plasma treatment is preferably carried out until the desired state has been established or the particular values of the light fastness, wash fastness and rub fastness which characterize the dyed polyolefin fibers according to the invention have been established.
  • the advantages of the process according to the invention can be seen in the fact that the polypropylene fiber materials subjected to prior activation of a vat dyeing have outstanding fastness properties after the dye fixation, with simultaneously deep and brilliant color shades. Such values were not achievable by the previously known method.
  • a further advantage of the invention lies in the possibility of dyeing fiber blends of polypropylene, in particular cellulose fiber materials, in one step within the scope of the invention.
  • the color yield in the dyeing can be increased by at least 55%, in particular by at least 120%, compared to the non-plasma-treated polyolefin fiber.
  • a polypropylene fabric having a basis weight of 130 g / m 2 each in the dimension of 30 cm (warp) x 15 cm (weft) is used.
  • the tissue is prefixed at 130 ° C. for 30 seconds in a suitable tenter. Subsequently, the fixed tissue is subjected to a plasma treatment using the following parameters:
