Definitions

  • the present invention relates to a stain and soil repellent composition for carpets.
  • the invention especially relates to a stain and soil repellent composition for carpets made from polyamide, wool and their mixtures.
  • a stain repellent can be applied to a carpet in a continuous or discontinuous process, in which between 3 and 7 weight-% of the stain repellent relative to the pile weight (the weight of the utilized fiber) is used. It is also known that considerably higher concentrations, for example up to 10 weight %, can be utilized.
  • a separate treatment bath is utilized after the dyeing step, in which the stain repellent is applied to the carpet at a pH between 2.5 and 7.
  • the stain repellent is applied to the carpet with suitable devices, such as a waterfall applicator, immersion tank and Fluider® apparatus.
  • a treatment with a fluorocarbon compound follows as the last finishing step, for example with a desired concentration of from 1.0 to 1.6 weight-% of fluorocarbon relative to the pile weight of the carpet.
  • the application of the fluorocarbon compound typically precedes the dryer of the continuous dye unit or is prior to the coating oven.
  • the simplest procedure is a spray application which is carried out with a suitable spray device.
  • the fluorocarbon compound is applied as an aqueous solution to a dry or lightly moistened carpet.
  • the most often-used application method is a foam application. With this system, a highly concentrated solution of the fluorocarbon compound can be applied to the carpet as a foam with minimal wetness.
  • special foaming aids are added to the fluorocarbon compounds, which then degrade at the selected drying temperatures, and the fluorocarbon compound remains on the fiber and bonds to it.
  • the two-step process is time consuming, relatively high cost, and resource intensive.
  • the application of the stain repellent together with the fluorocarbon in a single step is advocated.
  • the task of the present invention is to provide an improved stain and soil repellent composition compared to the current state of technology.
  • This task was achieved according to the invention by using a combination of two different stain repellents together with a fluorocarbon compound to impart desirable stain and soil repellent properties to carpets.
  • the present invention is a stain and soil repellent composition which encompasses the following components:
  • hydroxyaromatic compounds are compounds which have at least one, preferably one or two, aromatic nucleus, and at least one hydroxyl group directly bound to the nucleus or one of the nuclei.
  • Other substituents can be bound to the nucleus besides the hydroxyl group, for example halogens, or sulfonic acid groups.
  • Ring systems with 6 to 12 carbon atoms are preferred as the aromatic nucleus, for example phenyl or naphthyl radicals with an OH group in the 1, 2, or 3 position.
  • substituted and non-substituted phenol, 1-naphthol, and 2-naphthol are substituted and non-substituted phenol, 1-naphthol, and 2-naphthol.
  • Hydroxyaromatic compounds with more than one hydroxyl group at the nucleus are also suitable, for example di-hydroxyaromatic compounds such as resorcinol and catechol, or tri-hydroxyaromatic compounds such as pyrogallol (1,2,3-tri-hydroxybenzol).
  • di-hydroxyaromatic compounds such as resorcinol and catechol
  • tri-hydroxyaromatic compounds such as pyrogallol (1,2,3-tri-hydroxybenzol).
  • aromatic nuclei can also be covalently bonded over a functional group, for example a sulfone group.
  • condensation products of the hydroxyl aromatic compounds with formaldehyde according to the invention are inherently easy to make and are known to those skilled in the art.
  • novolak with linear chains can be obtained from an acid catalyzed reaction of excess phenol with formaldehyde, in which the phenol units are bonded with methylene bridges. Utilizing a basic catalyst and excess formaldehyde, phenol and formaldehyde are condensed to resoles.
  • the aromatic adducts either already have sulfonic acid groups or they can be attached after a typical condensation, for example, through a reaction with sulfur trioxide, chlorosulphonic acid, or amidosulphonic acid.
  • a condensation reaction of the OH-groups of the sulphonic acid group can occur, so that the end products of the condensation reaction do not have any free sulphonic acid groups and, therefore, can be utilized as a condensation product according to component (a) of the present invention.
  • condensation products without sulphonic acid and carboxyl groups can be obtained, for example, under the name ZELAN® 8236 from DuPont, Wilmington, DE, USA.
  • ZELAN® 8236 is a base catalyzed condensation product of 4,4'bis(hydroxyphenyl) sulfone and formaldehyde.
  • Condensation products with sulphonic acid groups are commercially obtainable, for example, from Zschimmer & Schwarz Mohsdorf GmbH & Co., Mohsdorf, Germany under the name Zetesal NT and from CHT R. Beitlich GmbH, Tubinen, Germany under the name Rewin KBL or Rewin KF as well as Tubicoat KF.
  • the essential element of the present invention is that at least one condensation product, which is free of sulphonic acid and carboxyl groups, and at least one condensation product, which is at least partially sulphonated are used together. This combination enables the application at neutral pH and yields unexpectedly improved stain repellency, as shown in the examples below.
  • compositions according to the invention contain, furthermore, at least one fluorocarbon compound (c), and, if required, at least one foaming aid (d). If a commercial product is being used for the component (c), then the foaming aid may already be contained in the commercial composition, so that it does not need to be added additionally to the composition. Based on the possible inherent foam building properties of the utilized components, it is possible, that by stirring alone, the compositions can create foam, and the addition of a foaming aid (d) is, therefore, not required. However, it can be helpful to add further foaming aids (d) to the stain and soil repellent composition of this invention despite inherent foam building properties of (c).
  • the fluorocarbon compound of the component (c) is utilized together with the condensation products of the components (a) and (b) to impart oil, water and soil repellent properties to the substrate.
  • Anionic, cationic or non-ionic as well as amphoteric fluorine compounds are in principle used as fluorocarbon compounds, which are also commercially available.
  • fluorine containing polyacrylates US Patent No. 3,574,791 and US Patent No. 4,147,851
  • fluorine containing urethanes US Patent No. 3,398,182 and US 2003/0204015 A1

  • Zonyl® 19087 Zonyl® 9535, Zonyl® 555 and Zonyl® 5180.
  • Zonyl® 9087 DuPont
  • the production of such fluorocarbon compounds is known to those skilled in the art and can be accomplished, for example, by attaching linear fluorinated chains called fluorotelomers to organic polymers.
  • fluorotelomers For example, tetrafluoroethylene (TFE) is reacted to form a fluorocarbon compound in a telomerization process.
  • TFE tetrafluoroethylene
  • Fluorocarbon compounds can be subdivided basically into three molecular regions.
  • Perfluoroalkyl groups are responsible for soil repellency as well as hydrophobation and oleophobation.
  • a spacer gives the required molecular flexibility, so that the fluorocarbon compound is soluble and/or emulsifiable.
  • An anchoring and/or adhesive group ensures the permanency of the fluorocarbon compounds.
  • Preferred anchoring groups are those based on urethane.
  • foam builders such as alkyl amine oxides, for example Laviron 118SK, Cognis Germany GmbH & Co. KG, Dusseldorf, Germany, can be utilized as additional foaming aids for component (d).
  • alpha - olefin sulfonate such as Reworyl AOS 38 or Sulframin AOS 38 (Goldschmidt GmbH, Germany); and modified lauryl sulfate, such as Tubicoat ELS (CHT R. Breitlich GmbH, Germany) and Baygard Foamer (Lanxess Europe (GmbH & Co KG, Germany) are suitable foam builders.
  • Foaming aids are being utilized for foam improvement methods by adding them directly to the finishing agent, which is to be foamed.
  • the stain and soil repellent compositions of the present invention are prepared in water (e) as solvent.
  • At least one plasticizer (f) can be present in the compositions according to the invention.
  • Polysiloxane compounds such as amino functional polydimethylsiloxane; fatty acid condensation products, such as condensation products of hydrated tallow with 2-[2-aminoethyl)-amino] ethanol; and acetate salt (CAS No. 68425-52-5) or acryl compounds such as bis [acryloxyethyl]-hydroxymethyl ammonium methyl sulfate (CAS No. 93334-15-7) are suitable in principle as plasticizers.
  • a plasticizer from the above mentioned compounds or a mixture of them can be included in the composition according to the invention.

KG, Geretsried, Germany; Raniesoft TS 20 (fatty acid condensation product) of Ranie Chemie, Wiehl, Germany; Softycon N (fatty acid condensation product) Textilcolor AG, Sevelen, Switzerland; and Zefasoft NI (fatty acid condensation product) of Zschimmer & Schwarz Mohsdorf GmbH & Co. KG, Mohsdorf, Germany.
  • At least one fluorotenside (g) can be included in the composition according to the invention. Better penetration to a carpet with the stain and soil repellent according to the invention is achieved with addition of the fluorotenside.
  • Suitable fluorotensides are obtained, for example, from DuPont Specialty Chemicals under the name Zonyl®.
