Definitions

  • the present invention relates to water repellents and oil repellents based on perfluoroalkyl group-containing polymers.
  • fluorine compounds are rarely used alone in equipment formulations.
  • urea resins, melamine resins or other resins mostly based on methylol compounds.
  • fluorine compounds are combined with extenders, e.g. with paraffin fractions or paraffin waxes and / or fatty acid esters and melamine resins (cf. Chwala / Anger: "Handbuch der Textilosstoff", Verlag Chemie-Weinheim-New York 1977, pages 745 to 747, 721).
  • Suitable components A) are commercially available perfluoroalkyl polymers from the series of perfluofalkyl group-containing vinyl, styryl, vinylidene, acrylic, methacrylic and ⁇ -chloroacrylic polymers with 4 to 20 carbon atoms in the perfluoroalkyl radical.
  • Preferred compounds are acrylate (co) polymers with a fluorine content of 20 to 45, in particular 35 to 45% by weight.
  • Such compounds were preferably used in the form of their aqueous emulsions or dispersions.
  • the cationically modified polyurethanes are very particularly preferably used in the form of their aqueous solutions or dispersions and contain a content of incorporated ternary or quaternary ammonium groups which ensures their solubility or dispersibility in water, and, if appropriate, of built-in ethylene oxide units present within a polyether chain, the content of ternaries or quaternary ammonium compounds at 2 to 300 milliequivalents per 100 g of solid and the content of the ethylene oxide units mentioned is from 0 to 25% by weight, based on the solid.
  • the agents according to the invention serve in particular as textile finishing agents for the phobing of textiles. They are in the form of aqueous dispersions with a solids content of 10 to 50%, preferably 15 to 40%. With a solids content of 15% this is Mixing ratio of perfluoro compound A) to cationically modified polyurethanes B) in the finishing liquor, for example at 0.5: 1 to 10: 1, in particular at 1: 1 to 5: 1, based on the solids content.
  • aqueous dispersions according to the invention can contain further components such as other textile auxiliaries, e.g. Synthetic resins.
  • These further constituents are preferably nonionic or cationic in nature.
  • the aqueous dispersions are diluted with water before use on the textile materials.
  • the application amounts are chosen so that a coating amount of 0.5 to 15 g, preferably 0.5 to 5 g and in particular 0.5 to 1.5 g of solids of the substance according to the invention per kg of textile material is obtained.
  • natural and synthetic materials such as fibers, filaments, yarns, nonwovens, fabrics, knitted fabrics and knitted fabrics made in particular of cellulose and its derivatives but also of polyester, polyamide and polyacrylonitrile materials, wool or silk can be successfully finished.
  • hydrophobized or oleophobicized textile structures such as nonwovens or, in particular, fabrics are used, for example, for the production of umbrella coverings, tents, water-repellent clothing or covers, balloon envelopes, awnings, textile floor coverings, packaging materials or footwear,
  • the finishing is carried out by known methods, preferably by the pull-out or padding method, for example between room temperature and 40 ° C., but also by splashing or spraying with a subsequent temperature treatment at 80 to 180, preferably 120 to 150 ° C.
  • a cotton gabardine fabric with a m2 weight of approx. 240 g was equipped with the following formulations:
  • the cotton fabric was soaked in a chassis with the liquors and squeezed between 2 rubber rollers (foulard).
  • the liquor absorption was 70% based on the textile weight.
  • the samples were dried at 100 ° C and condensed at 150 ° C for 5 minutes.
  • the grade for oil repellency corresponds to the highest numbered test liquid that does not wet the fiber material within 30 seconds: Grade 1 lowest value Grade 8 highest value.
  • Component I added according to the invention already gives this increase with use, based on solid substance, of 1.5 g / l, while component III, which is not in accordance with the invention, is effective only when 10 g / l is used.
  • the cotton swatches finished in Example 1 were washed 5 times at 40 ° C. on a Miele washing machine type W 763 washed with an easy care program with the addition of a household detergent and dried at 80 ° C in a Miele household dryer.
  • Component I added in accordance with the invention improves the wash resistance of fluorine finishes in such a way that even after 5 machine washes, the phobia values are retained, while the finishes without extender or with component III drop significantly.
  • a dyed polyester / cotton poplin fabric (67% PES / 33% cotton) with a weight of approx. 160 g m2 was equipped with the following formulations on the foulard:
  • Component I added according to the invention improves the wash resistance in such a way that even after 5 machine washes, the phobic values are almost completely retained,
  • a wool fabric with a weight of 280 g / m2 is padded as follows:
  • the fleet uptake was 80%. After treatment at 100 ° C, the tissues are treated for 3 minutes at 140 ° C:
