Definitions

• the object of the invention is to provide a method for easy care of textile materials consisting of cellulose fibers or containing cellulose fibers in a mixture with other fibers using formaldehyde-free finishing agents, in which one achieves finishing effects while maintaining high degrees of whiteness finished textile goods can be compared with the effects of formaldehyde-containing finishing agents in relation to the shrink and crease resistance behavior.
• Textile materials are understood to mean, for example, fabrics, knitted fabrics, knitted fabrics, yarns and fibers in all processing stages.
• the textile materials either consist of cellulose fibers or contain cellulose fibers in a mixture with other fibers, e.g. in a mixture with polyester fibers, polyamide fibers such as nylon, wool and polyacrylonitrile fibers.
• the textile materials are impregnated with an aqueous liquor which contains an finishing agent and a catalyst for crosslinking the finishing agent.
• a procedure is also possible in which the textile materials are first impregnated with an aqueous liquor which only contains the finishing agent and the catalyst is then applied to the fabric in a separate process step.
• the mode of operation is preferred in which the finishing agent and catalyst are applied to the textile material in solution in a liquor.
• Compounds of this type can be obtained, for example, by the process known from EP-PS 00 36 076. Accordingly, they are obtained by condensing compounds such as N, N'-dimethylurea, N-methylurea, N, N'-diethylurea, N-ethylurea, Nn-propylurea, N-isopropylurea, N, N-di-n-propylurea, N, N'-di-isopropylurea with glyoxal in the acidic pH range.
• the molar ratio of the substituted ureas to glyoxal is 1 to 1.1 to 1.
• the compound of formula I is preferably used as the finishing agent in which the substituents R1 and R2 are a methyl group and the substituents R3 and R4 are each hydrogen, ie N, N '-Dimethyl-4,5-dihydroxyethylene urea.
• the concentration of the compounds of the formula I in the finishing liquor is 20 to 100, preferably 30 to 60 g / l.
• the equipment fleet contains as another essential component (b) zinc fluoroborate or mixtures of zinc fluoroborate with other catalysts customary in high refinement, such as magnesium chloride, magnesium hydrogen phosphate, magnesium fluoroborate, aluminum chloride, aluminum sulfate, zinc nitrate or zinc chloride.
• the finishing liquor contains, based on the finishing agents of formula I dissolved therein, 4 to 14 and preferably 8 to 14% by weight of zinc fluoroborate or the mixtures of zinc fluoroborate in question with the other catalysts customarily used in high refinement.
• the amount of zinc fluoroborate in all mixtures should be chosen so that at least 50% by weight of zinc fluoroborate, based on the finishing agent (a), is used.
• the catalyst mixtures those of zinc and magnesium fluoroborate are of particular interest.
• the other catalysts for high refinement which can optionally be used together with zinc fluoroborate are used in amounts of 0 to 8% by weight, based on the finishing agent (a).
• the equipment fleet contains at least one compound of the formulas as a further component (c)
• the compounds of formulas II and III can be used either alone or in a mixture. They are contained in the equipment fleet in amounts of 0.01 to 1.0, preferably 0.05 to 0.5% by weight, based on the fleet.
• the finishing liquor may optionally also contain other customary auxiliaries, for example water repellents, plasticizers, leveling agents, wetting agents and finishing agents and handle variators.
• Hydrophobing agents are, for example, aluminum or zirconium-containing paraffin wax emulsions and silicone-containing preparations. Oxygenation products of higher fatty acids, fatty alcohols or fatty acid amides, higher molecular weight polyglycol ethers, higher fatty acids, fatty alcohol sulfonates and N-stearylurea compounds may be mentioned as plasticizers.
• Leveling agents can be used water-soluble salts of acidic esters of polybasic acids with ethylene oxide or propylene oxide adducts, longer-chain oxyalkylatable basic bases.
• Wetting agents are, for example, alkylnaphthalenesulfonic acids, the alkali metal salts of sulfonated succinic acid dioctyl ester and the addition products of alkylene oxides with fatty alcohols, alkylphenols or fatty amines.
• Cellulose ethers or esters and alginates are suitable as finishing agents.
• Dispersions of synthetic polymers and polycondensates are also suitable for this purpose; the auxiliaries which may be considered are generally used in amounts of 0.3 to 4, preferably 1 to 2.5,% by weight, based on the dry textile material.
• Suitable handle variators for the process according to the invention are very well silicone softeners, preferably amino-functional polydimethylsiloxanes with a content of 0.2 to 5.0 percent by weight of amine, based on the remaining polydimethylsiloxane. This not only gives the finished goods a very soft feel, but also their wrinkling behavior is positively influenced.
• the textile materials are impregnated with finishing liquors of the type described above.
• the only essential for the success of the method according to the invention is the fact that the constituents specified under (a), (b) and (c) are applied to the textile material.
• the easiest way to meet this requirement is to dissolve the three components mentioned in an aqueous liquor and apply them to the textile material.
• each component can also be dissolved in an aqueous liquor and applied to the textile material.
• the easiest way to treat the textile material with the aqueous liquor is by means of a padder and pressing off the excess liquor.
• the fleet recordings are in the range of 50 to 120%.
• it is also possible to treat the textile materials with components (a) to (c) by spraying, splashing or foam application.
• the impregnated textile materials are dried and then fixed, in which the textile material is briefly heated to temperatures in the range from 140 to 180.degree.
• the finishing agents are cross-linked with the cellulose fibers and with each other.
• the fixing takes about 20 seconds to 7 minutes, preferably 40 to 280 seconds. The higher the temperature when fixing, the shorter the dwell time at the temperature used in each case.
• the following examples and comparative examples illustrate the degree of easy care equipment based on the following characteristics. Dry crease angle (sum of warp and weft according to DIN 53 890), Wet crease angle (Tootal method BP 727 890) Monsanto picture, md, after a single 20-minute wash at 60 ° C, Wash shrink for warp and weft after washing once every 20 minutes at 60 ° C, tear strength (weft) measured according to ASTM D 1682-84-175 and Whiteness measured in percent using an Elrepho photometer.
