  • Patent number: 5393859
    Abstract: Organopolysiloxanes in which two polysiloxane chains are bonded via a divalent radical can be obtained by reaction of cyanuric halides with organopolysiloxanes which contain primary amino groups in substituents. The divalent radical contains 1,3,5-triazine rings, to which a halogen atom is still bonded. The organopolysiloxanes thus obtained are suitable for soft handle treatment of fiber materials. In particular, textile sheet-like structures which comprise cellulose fibers can thereby be given a soft handle and improved permanence of the treatment effects with respect to washing processes.

  • Patent number: 5310783
    Abstract: Stable, low-viscosity dispersions of polysiloxanes containing amino or amido groups can be obtained, even at comparatively high concentrations and/or pH values, by adding a product of the formulaR1--CH(X)--Y--O--R2(R1 is H, CH.sub.3 ; X=OH, NH.sub.2 ; R2=C.sub. -C.sub.4 -alkyl, unsubstituted or substituted by OH or OR3; R3=C.sub.1 -C.sub.4 -alkyl, unsubstituted or substituted by OH) to the dispersions.The dispersions are suitable for the treatment of fiber materials, especially textiles, to which a soft handle is thereby imparted.

  • Patent number: 5214121
    Abstract: Diols containing perfluoroalkyl radicals are produced by reacting compounds of the formulaR.sub.f --(E).sub.m --X'--H(R.sub.f =perfluoroalkyl radical, E is an alkylene group optionally interrupted by certain groups and/or substituted at the end, m=0 or 1, X'--H=--CONRH, --SO.sub.2 NRH or --SH) in a first step with diols containing at least 2 halogen atoms. Preferably the obtained products are reacted in a second reaction step with polyvalent isocyanates to prepolymers with free --NCO-- or free --OH--groups and these prepolymers are reacted in a third step with compounds containing isocyanate groups and/or hydroxyl groups. The first reaction step is carried out in an aprotic solvent which is insoluble in water, in the presence of an aqueous solution of an alkali metal carbonate. Intermediate products have not to be isolated.The obtained polyurethanes can be used in form of aqueous dispersions for the oil- and water repellent finishing of textiles.

  • Patent number: 5196260
    Abstract: The present invention relates to a process for the treatment of fibrous materials with modified organopolysiloxanes, wherein, in an aqueous medium, an organopolysiloxane copolymer prepared in a first stage from customary cyclic siloxanes (A) and unsaturated silanes (B) in the presence of a crosslinking agent and emulsifier (1) is copolymerized in a second stage with at least one vinyl monomer in the presence of emulsifiers (2), and the resulting dispersion of the modified organopolysiloxane copolymer is applied to the material in the customary manner and the material is dried and subjected to condensation.The process has the advantage that the materials, in particular textiles, treated by the process, above all coated by the process, have very good waterproof properties and at the same time good to very good water repellency. However, the materials are simultaneously distinguished by a pleasant soft handle, without the degree of whiteness thereof being noticeably impaired.

  • Patent number: 5112930
    Abstract: Modified polyurethanes containing perfluoroaliphatic groups which are obtained by reacting oligo(poly)urethanes containing free hydroxyl or isocyanate groups and perfluoroaliphatic groups with di/polyfunctional polysiloxanes at elevated temperatures with conversion of all the reactive groups of the urethane are used for the oil- and water-repellent finishing of fiber materials, conferring on these materials thus treated not only laundering- and drycleaning-stable effects but also in particular a very soft, full hand of very good surface smoothness, these excellent hand effects being further optimized by the addition of a polyethylene dispersion and/or of further customary textile assistants, in particular water-repellent fluorocarbon compounds.

  • Patent number: 5047065
    Abstract: An aqueous finishing agent for providing fibrous materials with a soft water and oil repellent treatment is provided. The finishing agent comprisesA) 25 to 65% by weight of a perfluoroaliphatic group-bearing water/oil-repellent agent (at least 5% by weight fluorine) in dispersion,B) 10 to 35% by weight of a dispersion of an emulsifiable polyethylene (density at 20.degree. C. at least 0.92 g/cm.sup.3, acid number at least 5) andC) 25 to 40% by weight of a fluorine-free dispersion of a soft-hand extender based on a modified hydrogen alkyl polysiloxane. A process for providing fibrous materials with a soft water and oil repellent treatment is also provided. The finishing agent provides fibrous material with excellent properties which are resistant to washing and dry cleaning and a particularly smooth, soft hand.

  • Patent number: 4895927
    Abstract: The present invention contains a process for manufacturing a water-soluble, self-crosslinking, polymeric condensation product by reacting 1 mole di-C.sub.1-4 -alkylamino-C.sub.24 alkyl(meth)acrylates with 0.3 to 1.5 mol di-C.sub.1-3 -alkyl-phosphonates in the presence of water under heating up to a remarkable increase of the viscosity.If aqueous solutions of these condensation products are used for the treatment of fibrous materials, a very high antistatic effect is imparted to them with only small changes of shade and a very good dry- and wet rubbing fastness as well as water-fastness. The effects show a good permanency.
