Description

INTERLACING OF CELLULOSE FIBER MATERIALS DESCRIPTION OF THE INVENTION The present invention relates to a process for interlacing cellulosic fiber materials. The cellulosic fiber materials are interlaced to impart permanent finishing effects, for example, in the area of resistance to crease formation, easy care, dimensional stability, and shrinkage resistance. It is known to treat cellulosic fiber materials, such as textiles, with products that confer permanent finishing effects, for example shrinkage and crease resistance. The products used for this purpose include, for example, products obtained through the addition of formaldehyde to amide groups. These N-methylol compounds normally continue to comprise free formaldehyde remnants and can remove formaldehyde to a certain degree when subjected to a heat treatment, which can lead to an annoying odor and intolerance. This disadvantage of the N-methylol compounds can be reduced or avoided by using products with a low formaldehyde content or formaldehyde-free as interleavers for cellulose. The contemplated products have etherified N-methylol groups or do not contain any -N-CH2-O- group. An example of the last class of compounds is N, N'-dialkyl-4,5-dihydroxyimidazolidinones (N, N - dialkylhydroxyethylene ureas), which can be obtained by reacting N. N'-dialkylureas with glyoxal. Similarly, the etherification products of the aforementioned compounds with polyhydric alcohols are known as crosslinkers for cellulosic materials. The disadvantage of the formaldehyde-free cellulose crosslinkers of the prior art is that the desired level of effect is not achieved in all cases. In addition, known products generally require temperatures of about 160 ° C or higher for an adequate crosslinking reaction with cellulose, which is undesirable. The formaldehyde-free interlayers, in addition, require relatively high or very high usage levels and additions and frequently lead to undesirable yellowing of the treated fiber materials. It is an object of the present invention to provide a method for interlacing cellulosic fiber materials, for example, in order to obtain a highly effective formaldehyde free finish of the fiber materials, which do not have the disadvantages described. The process makes it possible to carry out the reaction of the crosslinker with the cellulose (cure) at comparatively low temperatures, i.e., temperatures less than 1 50 ° C, and must lead to a higher level of resistance to crease or effect. It is easy to care for as far as possible using familiar freelanders of formaldehyde. This object is achieved through a procedure for interlacing cellulosic fiber materials, especially cellulosic fiber materials, which are from 20 to 100% by weight of natural or regenerated cellulose, which comprises applying to the cellulosic fiber materials, wherein the cellulosic fibers comprise natural or regenerated cellulose, at least one product of the general formula (1): > -E »J O). wherein A is an aliphatic, aromatic or heteroaromatic radical, R is a radical reactive to the fiber, and n is 1, 2, 3 or 4, provided that the radical [R] n includes at least two reactive groups to the fiber. A is preferably an aromatic radical, which may be unsubstituted or substituted by C 1 -C 4 alkyl, for example, methyl or ethyl, C 1 -C alkoxy, for example methoxy or ethoxy, halogen, eg, fluorine, bromine or especially chlorine, carboxyl or preferably one or more water solubilization groups. Water solubilization groups include especially sulfo groups (-SO3H). An aromatic radical A is preferably a benzene radical, which can be substituted by one or two sulfo groups. The aromatic radical A preferably also can be free of water solubilization groups, if at least one of the radicals R contains a water solubilization group, for example, a sulfate group.

A aliphatic can be, for example, an alkyl radical of C? -C 18, preferably a C 2 -C 2 alkyl radical, which can be interrupted by one or more heterogeneous atoms, for example, oxygen, and which can be replaced by one or more water solubilization groups. Examples of suitable water solubilization groups are the sulfo groups and the hydroxyl groups. A heteroaromatic is, for example, a morpholino, pyrimidine or triazine radical, which can be substituted, for example, by halogen. The radicals reactive to the fibers are radicals capable of reacting with the hydroxyl groups of cellulose, the amino, carboxyl, hydroxyl or thiol groups in the case of wool and silk or with the amino or possibly carboxyl groups of synthetic polyamides with the formation of bonds covalent chemicals. The fiber-reactive groups are generally linked directly or through a bridge member to the colorless radical A. Examples of suitable reactive groups to fibers include those which contain at least one separable substituent on an aliphatic, aromatic or heterocyclic radical, or in which the radicals mentioned contain a radical suitable for reaction with the fiber material, for example, a triazine radical. Examples of the fiber-reactive groups include radicals reactive to fibers containing 4, 5 or 6 carbo- or heterocyclic rings substituted by a separable atom or group. Examples of heterocyclic radicals include radicals which contain minus a separable substituent attached to a heterocyclic ring; and those containing at least one reactive substituent attached to a 5- or 6-membered heterocyclic ring, such as a monoazine, diazine, triazine, pyridine, pyrimidine, pyridazine, pyrazine, thiazine, oxazine or an asymmetric or symmetrical triazine ring. The radicals reactive to heterocyclic fibers mentioned further contain, via a direct bond or via a bridge member, more radicals reactive to fibers, such as the radicals described, for example. The fiber reactive groups further include those having at least one activated unsaturated group, especially an unsaturated aliphatic group, for example, a vinyl, halovinyl, styryl, acryloyl or methacryloyl group, or at least one polymerizable ring system. Examples of such groups are unsaturated groups substituted by halogen, such as the halomaleic acid and halopropionic acid radicals, a- or β-bromo- or -chloro-acryloyl groups, halogenated nylcetyl vi groups, halocrotonyl or halomethacryloyl groups. Also suitable are groups which, for example, through the hydrogen halide bond, are easily converted to halogen-containing unsaturated groups, for example, dichloro- or dibromo-propionyl. In the present it is understood that halogen means not only fluorine, chlorine, bromine and iodine atoms, but also pseudohalogen atoms, for example, cyano. The process of the present invention provides good results in the use of compounds containing an a-bromoacryloyl group. Among the compounds that contain a double polymerizable link, preference is given to those containing at least one acryloyl, methacryloyl, a-bromoacyloyl, a-chloroacryloyl, vinyl or vinylsulfonyl radical; very preferably those containing at least one acryloyl, a-bromoacryloyl or vinylsulfonyl radical. Examples of more separable atoms or groups are ammonium, including hydrazinium, sulfate, thiosulfate, phosphate, acetoxy, propionoxy or carboxypyridinium. In formula (1), one of the four reactive radicals is not necessarily linked to radical A; rather, it is also possible that two or three active radicals can be linked together directly or via bridge members. The bridging member between the colorless radical A and the fiber-reactive radical, or between two or three fiber-reactive radicals, can be not only a direct bond, but also one of a very wide variety of radicals. The bridge member is, for example, an aliphatic, aromatic or heterocyclic radical; The bridge member can also be assembled from several of these radicals. The bridging member may contain at least one functional group, for example, carbonyl or amino, in which case the amino group may further be substituted by unsubstituted or substituted C 1 -C 4 alkyl with halogen, hydroxyl, cyano, alkoxy, Ci-C, C?-C4 alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfate An example of a suitable aliphatic radical is an alkylene radical having from 1 to 7 carbon atoms or a branched isomer of the same. The carbon chain of the alkylene radical can be interrupted by a heterogeneous atom, for example an oxygen atom. An example of a suitable aromatic radical is a phenyl radical, which can be substituted by a C 1 -C 4 alkyl, for example, methyl or ethyl, C 1 -C 4 alkoxy, for example, methoxy or ethoxy, halogen, example, fluorine, bromine or especially chlorine, carboxyl or sulfo, and an example of a suitable heterocyclic radical is a piperazine radical. Examples of said bridge members are the following radicals: -CO-N (R1) - (CH2) 2-3-; -C N (R,) - (CH2) 2-O- (CH2) 2-; -NÍR ^ -CO-ÍCH ^; -N (R,) -; -NÍ ^ MCHzk-O-íCHzk-; -O-ÍCH ^ -; -CHz-N (R?) -; (CH 2) 2 -CO-N 1 (CH 2).

The process of the present invention is useful for obtaining permanent finishing effects, especially to improve the resistance to crease formation, easy care properties, dimensional stability and shrinkage resistance of fiber materials comprising not less than 20% by weight of natural or regenerated cellulose fibers. When the proportion of the cellulose fiber in less than 20% by weight, the effect of the finish is too small to achieve the advantages of the process. The fiber materials may include cellulose fibers in a mixture with other fibers, especially composed of polyester or polyamide, or may consist exclusively of cellulose fibers. Suitable cellulose fibers include not only natural fibers such as cotton, but also fibers composed of regenerated cellulose, for example, short viscose rayon fibers. Also suitable are modal fibers, for example, polynosic fibers, and cupro fibers. The "lyocell" fiber is not used in the process of the present invention. The fiber materials suitable for the treatment, especially after the treatment, via the process of the present invention are especially textile fabrics or stitches. Without However, yarns whose resistance to stress can be increased through the application of the process of the present invention are also contemplated. An important and preferred field of use for the process of the present invention is the sponge tissue material. The high-quality sponge fabric shows a reduced fiber release, especially after application in laundry dryers. In the case of viscose fibers, the process of the present invention can prevent or at least reduce any change to the surface of the fiber, for example, due to the dyeing process. The method of the present invention has a number of advantages. The fiber materials to which the aforementioned products have been applied need only be dried at 80 to 130 ° C to obtain good easy-care effects. Temperatures of up to 150 ° C or more, as is necessary in the case of known formaldehyde-free crosslinkers, do not need to be used. In the process of the present invention, an alkaline interlacing liquor can also be applied through the wet-batch technique whereby, after application and a puncture procedure, for example, during the calendering of pad, the fiber material, for example in the form of a textile fabric, is stored at room temperature in a state where it is protected against drying and, after a certain drying period of, for example, 20 hours, is rinsed with water and dried. At least partial entanglement occurs during the residence in the wet state. The process of the present invention can also be used to reduce the formation of dry specks, especially important in the case of fabrics covering furniture. After application of the interlayer in the wet entanglement process, the finished and dried fiber materials often exhibit better whiteness than in the case of using known methods involving heat setting. In addition, the damage resistance of the finished fiber materials is often appreciably better than in known methods. The process of the present invention, moreover, is advantageously combined with other processes, for example, with a reactive dye in an alkaline medium or other processes which are carried out in an alkaline medium. The combination of the process of the present invention with the dyeing and fixing of reactive dyes is of great advantage. The process of the present invention, moreover, frequently offers the advantage of less damage to the photoresist of direct and reactive metals than in the case of existing processes. In the process of the present invention, to the fiber materials, which are preferably textile fabrics or stitches, a product of the formula (1) has been applied. However, it is also possible to apply mixtures of a plurality of products that fall within the formula (1). In addition, other desired products can be applied to these fiber materials at the same time as a n or o more products of the formula (1), for example, water repellents, oil repellents, or flame retardants. The application of said product mixtures can be effected through an individual treatment liquor, for example, through pad calendering, in which case the wet harvesting is generally not less than 50%, preferably from 60 to 80% , when these product mixtures are homogeneous mixtures. It is particularly advantageous for economic and ecological reasons to carry out the process of the present invention in such a way that a product of the formula (1) or a product mixture is applied to the fiber materials in the form of an aqueous solution or dispersion alkaline of this product or these products and the fiber materials are subsequently dried. They are preferably dried within the temperature range of 80 to 130 ° C, for example, by means of hot air; if necessary, however, other temperatures can also be used, for example, up to 140 ° C. In addition to the aforementioned addition of other products to the treatment liquor, a preferred embodiment of the process of the present invention also includes a reactive dye in a single operation. In this case, the treatment liquor comprises a reactive dye as well as one or more products of the formula (1) and optionally other products. This preferred embodiment of the process of the present invention is contemplated especially for alkaline treatment liquors, whose pH is preferably within the range of 7 to 13 at 20 ° C.

With respect to the stability of the solutions or dispersions, it is usually advantageous that the solutions or dispersions, preferably aqueous solutions or dispersions, which will be used in the process of the present invention have a pH in storage that is not below 7.0 and does not above 10.0, in some cases not above 9.0. The desired pH, for example within the range of 7 to 10, can be fixed or stabilized with Na 2 CO 3, K 2 CO 3, KHCO 3 or NaHCO 3, for example. The amount of alkali, for example of NaOH or KOH, required for the treatment of fiber materials (crosslinking reaction with cellulose) and / or for reactive staining should not be added just before use. Metal salts which are present in the alkaline aqueous medium and which are within the scope of formula (1) and are useful for the process of the present invention, can be monovalent and polyvalent metal cation salts. Particularly preferred monovalent metals or metal cations are sodium and potassium. The sodium or potassium salts of the water-soluble compounds of the formula (1) are particularly preferred. A preferred embodiment of the process of the present invention in this manner comprises using water-soluble products of the formula (1); these water soluble products in particular are sodium or potassium salts, which are used in aqueous finishing liquors. If only these sodium or potassium salts are used, they are preferably alkaline aqueous solutions. In presence of other additives, which are insoluble in water but dispersible in water, the process of the present invention is preferably carried out using aqueous dispersions. The dispersants required to disperse said additional finishing agents in water are known to one skilled in the art. The aqueous dispersions, which comprise other products as well as also at least one compound of the formula (1) likewise preferably have an alkaline pH within the range of a pH of 7 to 13. The treatment of the fiber materials through of the process of the present invention can be carried out by commonly known methods. It is particularly advantageous to apply solutions or dispersants comprising at least one product of the formula (1) through pad calendering. This treatment is preferably carried out with an aqueous liquor comprising from 1 to 12% by weight, based on the total liquor, of one or more products of the formula (1). Typically, the fiber material comprises from about 1 to 6% by weight of the formula (1), based on the total weight of the finished fiber material, after the subsequent puncture. The subsequent drying can be carried out in a known apparatus, for example, through hot air, and preferably it is carried out within the temperature range of 80 to 130 ° C. During the drying process, a temperature gradient may be present. The drying is accompanied by a reaction (entanglement) of the product of the formula (1) with cellulose. This reaction is achieved by the presence of an alkaline pH. As well as drying with hot air, it is also possible to treat saturated steam at temperatures between 98 and 105 ° C, for example, or to combine the hot air treatment with the saturated steam treatment. The entanglement with the OH groups of cellulose in this way is achieved by the presence of alkaline compounds. Even if the alkali compounds of the formula (1), for example metal salts of water-soluble compounds of the formula (1), are already used for the process of the present invention, it is advisable to add more alkaline compounds to the liquors of treatment. Especially sodium hydroxide and potassium hydroxide are highly useful for this purpose. Instead of the additional inclusion of these alkaline compounds in the treatment liquors, the process of the present invention can also be carried out in two stages. This is achieved, for example, through a first step of applying a first aqueous treatment liquor to the fiber materials, which comprises a product of the formula (1) and has a pH at which this liquor has a high stability , for example a pH of 7 to 10. This first aqueous treatment liquor may comprise other products, such as reactive dyes. The first treatment liquor can be applied through pad cayandraje. After calendering, the fiber material is dried. The second stage involves applying a second aqueous treatment liquor that it comprises the amount of the alkaline compound necessary for the interlacing with cellulose. This alkaline compound is preferably sodium hydroxide or potassium hydroxide. The application of the second liquor is followed by drying, for example, from 80 to 130 ° C, during which the entanglement occurs. The second treatment liquor can be, for example, a solution of sodium hydroxide or aqueous potassium hydroxide of relatively high concentration, for example, between 30 and 60% by weight. At the temperatures employed, for example 80 to 1 30 ° C, the presence of alkaline compounds causes it to be present in entanglement (cure) with cellulose. For this reason, the treatment of the fiber materials with the treatment liquid is preferably carried out at a pH within the range of 7 to 1 3 (measured at 20 ° C). The fiber materials treated by the process of the present invention are remarkable for good permanent finishing effects, especially easy care, dimensional stability and shrinkage resistance. The compounds used in the process of the present invention can be applied to the fiber material and fixed on the fiber in various forms, especially in the form of aqueous solvents, preferably through the exhaust method. After fixing, the treated fiber materials are washed thoroughly with cold and hot water, optionally in presence of an agent, which has a dispersing effect and promotes the diffusion of unfixed portions. The compounds of formula (1) which contain a solubilization group in water, for example a sulfo or sulfate group, are either present in the form of their free acid or preferably as their salts such as, for example, the salts of alkali metal, alkaline earth metal or ammonium metal, or as salts of an organic amine. Examples are the sodium, potassium, lithium or ammonium salts or the triethanolamine salt. The compounds of the formula (1) are either known or can be prepared similarly to known compounds. For example, the compounds of the formula (1) are, for example, reactive dye precursors, as described in WO 96/00399 or can be prepared similarly thereto. For the process of the present invention, the amounts in which the compounds of the formula (1) are used in the treatment baths, especially in dyebaths together with dyes, preferably reactive dyes, can vary within wide limits. In general, without advantageous amounts of 0.01 to 20% by weight, especially of 0. 1 to 15% by weight, by weight of the fiber. The treatment by the process of the present invention is preferably carried out through the exhaust method. The treatment generally occurs in an aqueous medium at a liquor ratio of, for example, 2: 1 to 60: 1, especially from 5: 1 to 20: 1. The temperature for the treatment varies from, for example, 20 to 100 ° C, especially 40 to 90 ° C, preferably 55 to 80 ° C. In a particular preferred embodiment of the process of the present invention, the entanglement of the cellulosic fiber is carried out prior to dyeing or together with its dyeing, especially after manufacture of the fiber. In a particularly preferred embodiment of the process of the present invention, the entanglement of the cellulosic fiber materials is carried out together with their staining.
