Definitions

• the present invention relates to a stain and soil protection composition for carpets.
• the invention relates to a stain and soil protection composition for carpets of polyamide, wool and mixtures thereof.
• stain and dirt protection chemicals are often applied.
• the application is usually carried out in two steps and consists of the application of a stainproofing agent followed by treatment with a fluorocarbon compound.
• Stainproofing agents can be applied to carpets by continuous and batch processes, usually using between 3 and 7% by weight of the stainproofing agent, based on the weight of the pile (the weight of the yarn used). It is also known to use much higher concentrations, for example up to 10% by weight.
• a separate treatment bath is used after dyeing in which the stainproofing agent is applied to the carpet at a pH of between 2.5 and 7.
• the stainproofing agent is applied to the carpet by suitable means, such as a waterfall applicator, dip tray, fluidyer.
• the final finishing step is usually followed by treatment with a fluorocarbon compound, for example at 1.0 to 1.6% by weight, based on the pile insert weight of the carpet.
• a fluorocarbon compound for example at 1.0 to 1.6% by weight, based on the pile insert weight of the carpet.
• the application of the fluorocarbon compound is normally carried out before the dryer of the continuous dyeing plant or before Coating oven.
• the simplest method is the spray application, which is carried out with the aid of a suitable spraying device.
• the fluorocarbon compound is applied as an aqueous solution to the dry or slightly damp carpet.
• the most commonly used application method is the foam application. With this minimum moisture system, highly concentrated solutions of the fluorocarbon compound can be applied as foam to the carpets.
• special foam auxiliaries which decompose at the drying temperatures used; the fluorocarbon compounds remain on the fiber and combine with it.
• This object is achieved according to the invention by providing a combination of two different stainproofing agents together with a fluorocarbon compound for introducing stain and soil protection properties into carpets.
• hydroxyaromatics are substances which have at least one, preferably one or two, aromatic nuclei which have at least one, preferably one hydroxyl group, which is bonded directly to the nucleus or one of the nuclei.
• other substituents may be bonded to the at least one nucleus, for example, halogens or sulfonic acid groups.
• aromatic nucleus preference is given to ring systems having 6 to 12 carbon atoms, for example phenyl or naphthyl radicals having an OH group in the 1, 2 or 3 position.
• substituted and unsubstituted phenol, 1-naphthol and 2-naphthol are suitable.
• the phenol substituted with at least one sulfonic acid group and 1- or 2-naphthol are particularly preferred.
• hydroxyaromatics having more than one hydroxyl group on the nucleus for example dihydroxyaromatics, such as resorcinol and pyrocatechol, or trihydroxyaromatics, such as pyrogallol (1, 2, 3-trihydroxybenzene).
• dihydroxyaromatics such as resorcinol and pyrocatechol
• trihydroxyaromatics such as pyrogallol (1, 2, 3-trihydroxybenzene
• multiple aromatic nuclei may be covalently linked together, for example via functional moieties, such as a sulfone moiety.
• condensation products of the hydroxyaromatics with formaldehyde which can be used according to this invention are in principle readily available and known to the person skilled in the art.
• phenol under acidic catalysis and phenol excess, phenol can be obtained with formaldehyde to novolacs with linear chains in which the phenol units are linked via methylene bridges.
• formaldehyde phenol and formaldehyde are condensed to form resoles.
• the aromatic starting materials can already carry sulfonic acid groups or these can be introduced after the condensation in a customary manner, for example by reaction with sulfur trioxide, chlorosulfonic acid or sulfamic acid. If the reactants already contain sulfonic acid groups, a condensation reaction at the OH group of the sulfonic acid grouping can take place by means of suitable process control, with which the end product of the condensation reaction no longer has any free sulfonic acid groups and thus can be used as the condensation product according to component (a) of the present invention.
• condensation products without sulfonic acid and carboxyl groups are available, for example, under the name ZELAN 8236 from DuPont, Wilmington, USA.
• ZELAN 8236 is a base-catalyzed condensation product of 4,4'-bis (hydroxyphenyl) sulfone and formaldehyde.
• Condensation products with sulfonic acid groups are commercially available, for example from Zschimmer & Schwarz Mohsdorf GmbH & Co. KG, Mohsdorf, Germany under the name Zetesal NT and from CHT R. Beitlich GmbH, Tübingen, Germany under the name Rewin KBL or Rewin KF or also Tubicoat KF available.
• An essential element of the present invention is that at least one condensation product free of sulfonic acid and carboxyl groups and at least one condensation product which is at least partially sulfonated are used together. This combination allows application at neutral pH and results in significantly improved stainproofing, as demonstrated by the examples below.
• compositions according to the invention also contain at least one fluorocarbon compound (c) and optionally at least one foaming aid (d). If a commercially available product is used for component (c), then the foam aid may already be present in it, so that it does not have to be additionally added to the compositions according to the invention. Due to the foam-forming properties inherent in the constituents used, it may also be possible for the compositions to form foam only by stirring and, for this reason, the addition of further foaming agents (d) can be dispensed with. However, despite the foam-forming properties of (c), it may be helpful to add further foam aids (d) to the stain and soil protection composition of this invention.
• the fluorocarbon compound of component (c) is used together with the condensation products of components (a) and (b) to impart oil, water and soil repellency properties to the substrates.
• the fluorocarbon compound anionic, cationic or nonionic as well as amphoteric fluorine compounds, which are also commercially available, can be used in principle. for example can fluorine-containing polyacrylates ( US 3,574,791 .

• Starting product is, for example, tetrafluoroethylene (TFE), which is further processed in a telomerization process.
• TFE tetrafluoroethylene
• Fluorocarbon compounds can in principle be subdivided into three molecular regions.
• the perfluoroalkyl groups are responsible for soil repellency as well as for hydrophobing and oleophobization.
• a spacer provides the necessary molecular mobility for the fluorocarbon compound to become soluble or emulsifiable.
• An anchor or adhesive group ensures the permanence of the fluorocarbon compounds. As anchor groups, those based on urethane are preferred.
• foaming agents such as alkylamine oxides, for example Laviron 118 SK, Cognis Deutschland GmbH & Co. KG, Dusseldorf, Germany, can be used as additional foam auxiliaries of component (d).
• alpha-olefinsulfonates such as Reworyl AOS 38 or Sulframin AOS 38 (Goldschmidt GmbH, Germany), modified lauryl sulfates such as Tubicoat ELS (CHT R. Breitlich GmbH, Germany), Baygard Foamer (Lanxess Europe GmbH & Co KG, Germany) ,
