Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION Laundry, which is laundered today in the home and in the industry, is uniform or, especially in the home, mostly of various types, especially natural fibers, mainly cotton or wool, regenerated cellulosic fibers such as bismuth. It consists of courses, synthetic fibers such as polyesters, polyamides and polyacrylonitriles, and mixtures of such fibers. So-called "white laundry" made of undyed fabric
Unlike (white wash), the so-called “colored laundry (col
An "ored wash)" usually consists of a fabric that is dyed lightly or pastel to dark with various shades and depths of color. It goes without saying that fabrics with the most various color fastnesses can be present in the laundry operation of colored laundry at home. If the dyeing is not fast enough to wash,
During the washing process, dyes or dye decomposition products leave and leach into the wash liquor. When these desorbed (leached) ingredients are reabsorption on another fabric that has been washed at the same time,
Due to redeposited dyes or dye degradation products, which may leach out and be unevenly distributed, "stainining", shade changes and / or spots formation occurs.
Desorption and / or decomposition of dyes from inadequately fast dyeings may depend, for example, on higher temperatures, repeated washings, liquor to wash liquor ratio, composition of the detergent used and its concentration in the liquor. Dyes from dyeings that are accelerated and in that case also the type of washing machine and the washing program used, are not sufficiently "suitable for domestic washing", for example due to mechanical stresses applied to the laundry during washing. Alternatively, it affects the elimination of dye decomposition products. Other reasons for the reduced fastness include also the quality of the water used (eg due to chlorine content), the composition of certain additives and the quality and structure of the dough material or fiber for easy handling. it can. Examples of this include laundry consisting of cellulosic fibers, especially cotton; these are usually direct dyes, reactive dyes, sulfur dyes, vat dyes or naphthol dyes, mainly direct dyes or reactive dyes. To be dyed with. Both direct dyeing and reactive dyeing of cellulose tend to "exude" to the wash liquor during repeated washing--and the wash liquor is consequently not fixed, for example. Including dyes, hydrolyzed dyes and / or decomposed and separated dyes-leading to the problems mentioned above.

Color transfer reactions are often divided into two constituent steps: -Detachment of dye particles from textile fibers-Redeposition of laundry elsewhere-in order to avoid this reaction, literature For various proposals.

On the other hand, the dye can be decomposed by oxidation while it is present in solution in the wash liquor. Using conventional heavy duty detergents, this is a perborate and persalt activator such as tetraacetylethylenediamine, T
Since it contains a bleaching system consisting of an AED, it usually does not present a problem. The resulting peracetic acid destroys the dissolved dye completely before it can be deposited on the fiber. However, the disadvantage here is that reactive perborate activators can also cause color damage by bleaching the color of the fabric.

In addition to bleach activators, enzymes with peroxidase properties are also suitable for these applications (Canada 2067748). Another possibility of avoiding color transfer is the incorporation of polymeric color transfer inhibitors into detergent formulations. In this case, the desorbed dye particles are complexed and stabilized by the polymer in the wash liquor, thus avoiding redeposition on the fibers.

Homopolymers of vinylimidazole and vinylpyrrolidone are used as preferred inhibitors. Canadian Patent No. 0094635 discloses a detergent formulation consisting of polyvinylpyrrolidone (PVP) with reduced color transfer during laundry operations.

Detergent additives for avoiding color transfer during washing--it consists of polymers based on N-vinylpyrrolidone, N-vinylimidazole or N-vinyloxazolidone--are published in German Patent Application No. It is known from JP 3803630. DE-A 3711 299 discloses polyvinylpyrrolidone grafted with vinyl ester as a graying inhibitor for fabrics made of synthetic fibers.

[0007]

The disadvantage of these polymeric color transfer inhibitors is that they often have low solubility, especially in the case of modified polyvinylpyrrolidone.
This makes it difficult to mix in liquid detergent formulations-
-And inappropriate biodegradability.

[0008]

[Means for Solving the Problems] Now these problems are
The use of the compounds defined below in washing or as a detergent additive leads to a better solution, i.e. they can be incorporated in powder as well as liquid detergents without problems and are also biodegradable. It has been found that a color transfer inhibitor is provided.

The present invention provides the formula I

[0010]

[Chemical 4] A polymer containing a repeating structural unit represented by and optionally another repeating structural unit obtained by hydrolysis / alcoholization from a monomer copolymerizable with vinyl acetate is eliminated to regenerate the dye and dye decomposition product. It relates to its use as a detergent additive to avoid sticking.

Formulas II and III

[0012]

[Chemical 5] It is preferred to use "partially" and / or "completely" hydrolyzed polyvinyl alcohols of

Polyvinyl alcohol is a polymer of vinyl alcohol which cannot exist in the free form and is prepared by the polymerization of stable vinyl acetate, followed by alcoholysis of the resulting polyvinyl acetate. The polymerization is carried out according to the principle of free radical chain polymerization in an organic solvent, usually methanol. The required free radicals are provided by decomposition in the reaction mixture by an initiator bearing a peroxy or azo group.

Polyvinyl acetate dissolved in methanol is converted into polyvinyl alcohol by transesterification with methanol (alcoholization). Preference is given to using bases, especially sodium hydroxide, as catalyst.

The content of residual acetyl groups can be adjusted by changing the catalyst concentration, reaction temperature and reaction time. Thereby a distinction is made between "fully" and "partially" hydrolyzed polyvinyl alcohol. Formula II
The partially hydrolyzed polyvinyl alcohol represented by can be theoretically understood as a copolymer of vinyl alcohol and vinyl acetate, wherein the content of vinyl alcohol is such that the full length molecule becomes water soluble. Up to The acetyl content is 88 mol% and the degree of hydrolysis of the underlying polyvinyl acetate and about 140
Generally about 11 corresponding to the number of mg KOH / g of ester
% By weight. The acetyl content can likewise be significantly higher: thus degrees of hydrolysis up to about 45-50 mol% are practically used.

The residual acetyl groups may be distributed on the polyvinyl alcohol chain in an irregular, regular or accumulating / blocking manner. The type of distribution is determined by the choice of catalyst and, if a solvent is used, its nature. The residual acetyl groups are thus distributed predominantly in blocks in the case of alkaline alcoholysis and predominantly randomly in the case of acidic alcoholysis.

In the case of partially hydrolyzed polyvinyl alcohols of the formula II, the compounds preferably used are those which have a residual acetyl content of less than 50% by weight, particularly preferably less than 30% by weight. .

The molecular weight M _w based on weight is 5000 to 3
0,000, preferably 20,000 to 200,000
0, particularly preferably 60,000 to 160,000. The values after reacetylation of polyvinyl alcohol in pyridine are shown here, yielding different numbers for each measuring method. The degree of polymerization P _w is 200-
It is 5,000, preferably 400 to 3,000.

Viscosity (4 wt% aqueous solution at 20 ° C. (D
IN53015)) is in the range of 2 to 50 mPa · s, preferably 10 to 30 mPa · s. The degree of hydrolysis (saponification degree) is preferably in the range of 70 to 95 mol%.

Fully hydrolyzed polyvinyl alcohol of the formula III is understood to mean polyvinyl alcohol having a degree of hydrolysis of about 97 to 100 mol%. In the case of fully hydrolyzed polyvinyl alcohol, the compounds preferably used are those having a residual acetyl content of less than 5% by weight, particularly preferably less than 2% by weight. The molecular weight M _w based on weight is 5,000 to
300,000, preferably 30,000 to 200,0
00, particularly preferably 60,000 to 120,000.

The degree of polymerization P _W is 100 to 5000, preferably 600 to 3000. Viscosity (4% by weight at 20 ° C
Aqueous solution of concentration, DIN53015) is usually 0.1-1
00 mPa · s, preferably 6 to 30 mPa · s, and particularly preferably 10 to 50 mPa · s.

The degree of hydrolysis (saponification degree) is preferably 98.
It is at least mol%. The polyvinyl alcohol used according to the invention is water-soluble and has a good biodegradability.

The solubility characteristics of polyvinyl alcohol are determined by the temperature (eg 90 ° C.) for a certain period of time under equivalent equipment conditions.
It can be determined by the amount of product that dissolves at (° C, 60 ° C, 40 ° C and 20 ° C) (dissolution curve). Relative rates of dissolution are determined by conventional laboratory methods. The dissolution operation time depends on the viscosity (K value) and the degree of hydrolysis.
However, very generally, at a temperature of 30 to 90 ° C., at least 10% by weight, preferably at least 50% by weight,
Particular preference can be given to using polyvinyl alcohols having a solubility of at least 90% by weight, the dissolution time being at most 45 minutes.

In the case of low-viscosity, partially hydrolysed polyvinyl alcohols having viscosities in the range from 2 to 10 mPa.s, about 96% of the polymer was found to dissolve after 30 minutes. However, the components which are not yet dissolved are completely dissolved at about 90 ° C. When dissolving fully hydrated polyvinyl alcohol, it was found that only a relatively small amount of polyvinyl alcohol was soluble. Only when this temperature is exceeded does significant dissolution occur, at which point at 90 ° C. a quantitative, clear, specks-free solution is obtained at 90 ° C.

The dissolution rate of polyvinyl alcohol is very greatly influenced by the presence of other products in the detergent and its nature and amount. In particular when the perborate / borate or ionic compound is present in relatively high concentrations, the polyvinyl alcohols with a degree of hydrolysis <80 mol%, which are preferred here, have been found to be particularly suitable for the intended use. . Furthermore, the polyvinyl alcohol type of copolymers (eg internally plasticized products, eg Mowiol® GE 4-86) have been found to be less problematic / suitable in this respect.

The polyvinyl alcohol used according to the invention can be used in various ways. When used in detergent powders, polyvinyl alcohol is usually used in the form of granules, the particle size being 200 to 1500 μm, the smallest particle size being 200 μm. When used in liquid detergents, polyvinyl alcohol is used in dissolved form. In this case, the polyvinyl alcohol can be added to the liquid detergent as a solution, preferably an aqueous solution, or it can be mixed as a powder while dissolving.
