Definitions
- graying inhibitors in the washing and aftertreatment of textile material containing synthetic fibers.
- the present invention has for its object to provide graying inhibitors for detergents and graying inhibitors for the aftertreatment of textile material containing synthetic fibers.
- graft copolymers which can be obtained by grafting a) polyalkylene oxides having a molecular weight (number average) from 2000 to 100,000 based on ethylene oxide, propylene oxide and / or butylene oxide with b) vinyl acetate in the weight ratio a): b ) from 1: 0.2 to 1:10 and their Acetate groups are optionally saponified up to 15%, as graying inhibitors in the washing and aftertreatment of textile goods containing synthetic fibers.
- the products to be used according to the invention are known (cf. DE-PS 10 77 430). They are obtainable by grafting polyalkylene oxides with vinyl acetate, the graft copolymerization being initiated by free radicals. For this purpose, one can either use conventional polymerization initiators, which break down into radicals under the polymerization conditions, or initiate the polymerization by high-energy radiation.
- Suitable polyalkylene oxides are polymers based on ethylene oxide, propylene oxide and / or butylene oxide, which have a number-average molecular weight of 2,000 to 100,000, preferably 4,000 to 50,000.
- the alkylene oxide units can be randomly distributed in the polymer or in the form of blocks, e.g. Block copolymers of ethylene oxide and propylene oxide, block copolymers of ethylene oxide and butylene oxide and block copolymers of ethylene oxide, propylene oxide and butylene oxide.
- the polyalkylene oxides in question are either dissolved in vinyl acetate and polymerized continuously or batchwise after addition of a polymerization initiator.
- a semi-continuous mode of operation is also possible, in which a part, e.g. 10% of the mixture of polyalkylene oxide, vinyl acetate and initiator to be polymerized is introduced, heated to the polymerization temperature and, after the polymerization has started, the rest of the mixture to be polymerized is added as the polymerization progresses.
- the graft copolymers can also be obtained by introducing polyalkylene oxide, heating to the polymerization temperature and adding vinyl acetate and starter either all at once, batchwise or, preferably, continuously.
- Particularly suitable polymerization initiators are organic peroxides, such as diacetyl peroxide, dibenzoyl peroxide, succinyl peroxide, di-tert-butyl peroxide, tert-butyl perbenzoate, tert-butyl perpivalate, tert-butyl permaleinate, cumene hydroperoxide, diisopropyl peroxidicarbonate, bis (o-toluoyl) peroxide, didecanoyl peroxide, dioctanoyl peroxide, dilauroyl peroxide, t-butyl perisobutyrate, t-butyl peracetate, di-t-amyl peroxide, t-butyl hydroperoxide and mixtures of initiators.
- organic peroxides such as diacetyl peroxide, dibenzoyl peroxide, succinyl peroxide, di-tert-butyl peroxide
- the polymerization can take place in the temperature range from 50 to 200.degree.
- the graft copolymerization is preferably carried out at 70 to 140 ° C. It can also take place under pressure.
- the graft copolymerization can be carried out in the manner of a Solution polymerization can be carried out in a solvent.
- Suitable solvents are, for example, alcohols, such as methanol, ethanol, n-propanol, isopropanol, n-butanol, sec-butanol, tert-butanol, n-hexanol and cyclohexanol, and glycols, such as propylene glycol, ethylene glycol and butylene glycol, and the methyl or Ethyl ether of the dihydric alcohols and dioxane.
- the graft copolymerization is preferably carried out in the presence of water as the solvent. When water is used as the solvent, there is initially a solution which, depending on the amount of vinyl acetate added, becomes a dispersion. If necessary, emulsifiers can also be used in this production method.
- graft copolymer or polyalkylene oxide and vinyl acetate Per 100 parts by weight of the graft copolymer or polyalkylene oxide and vinyl acetate, 5 to 100, preferably 10 to 50 parts by weight of a solvent or a solvent mixture, e.g. a mixture of isopropanol and water or a mixture of ethylene glycol and ethanol.
- a solvent or a solvent mixture e.g. a mixture of isopropanol and water or a mixture of ethylene glycol and ethanol.
- the weight ratio of polyalkylene oxide to vinyl acetate in the graft copolymer is 1: 0.2 to 1:10, preferably 1: 0.5 to 1: 6.
- Polyethylene oxide with a molecular weight (number average) of 2,000 to 100,000, in particular 4,000 to 50,000, is preferably used as the graft base.
- Up to 15% of the acetate groups of the graft copolymer can optionally be saponified.
- the saponification of the graft copolymers, which then leads to graft copolymers containing vinyl alcohol units, is carried out by adding a base, such as NaOH or KOH, or by adding acids, and optionally heating the mixture.
- the graft copolymers to be used according to the invention as graying inhibitors have a K value according to H. Fikentscher of 10 to 200, preferably 20 to 100 (determined in 1% strength by weight solution in ethyl acetate at 25 ° C.).
- the graft copolymers described above are used in detergents with a reduced phosphate content (this should be understood to mean a phosphate content of less than 25% by weight sodium triphosphate) or in phosphate-free detergents.
- the graft copolymers to be used according to the invention are added to commercially available detergent mixtures in an amount of 0.1 to 3, preferably 0.3 to 2% by weight, based on the detergent mixture.
- the graft copolymers can be added to the detergent formulation in the form of a paste, a highly viscous mass or as a solution in a solvent.
- the products can also adsor on the surface of agents such as Na2SO4 or builders (zeolites) as well as solid additives in the detergent formulation beers. It is also possible to add the products in finely divided form to the detergent formulation.
- the commercial detergents contain, in addition to phosphates (as builders), surfactants, e.g. C8- to C12-alkylphenol ethoxylates, C12- to C20-alkanol ethoxylates, block copolymers of ethylene oxide and propylene oxide, which are optionally end groups, anionic surfactants, such as C8- to C12-alkylbenzenesulfonates, C12- to C16-alkanesulfonates, C12- to C1 , C12- to C16alkylsulfosuccinates, sulfated ethoxylated C12 / C16 alkanols, and optionally also 0.5 to 3% by weight of an incrustation inhibitor, such as polymaleic acid, maleic acid / acrylic acid copolymers, polyacrylic acid or salts thereof, and also phosphate substitutes, such as zeolites in one Amount of 5 to 30% by weight, 3 to 25% by weight of
- the graft copolymers are also suitable as an additive in the aftertreatment of textile material containing synthetic fibers.
- they are added to the last rinsing bath of a washing machine cycle, the addition either being carried out together with a fabric softener usually used at this point or, if a fabric softener is not desired, used alone instead of the fabric softener.
- the amounts used are 0.01 to 0.3 g / l wash liquor.
- the use of the graft copolymers in the last rinsing bath of a washing machine cycle has the advantage that the laundry is soiled much less during the next washing cycle than without the addition of the graying inhibitor.
- the parts given in the examples are parts by weight, the percentages relate to the weight of the substances.
- the molecular weights (number average) of the polyether diols used were calculated from the OH number.
- the graft copolymers were prepared according to DE-PS 10 77 430 by grafting the parts of vinyl acetate shown in Table 1 to 100 parts of a polyethylene oxide with the molecular weight (number average) also given in the table.
- the K values of the graft copolymers are also given in Table 1.
- This graft copolymer was prepared by completely saponifying the graft copolymer 4 with NaOH.
- Polyester test fabric and polyester / cotton blend fabric were subjected to a series of 3 washes together with a standard dirt fabric. The dirty fabric is renewed after each wash, the test fabric becoming more soiled after each wash. The whiteness of the test fabric after the third wash is used to assess the degree of soiling, the values are secured by repeated repetition and averaging. It was measured in% remission using an Elrepho (Zeiss) filter 8.
- Test conditions: Tester: Launder-O-meter Water hardness: 3.5 ⁇ mol Ca / l, Ca: Mg 3: 2 Amount of liquor: 250 ml Fleet ratio: 1:10 Test temperature: 35 to 60 ° C Test duration: 30 minutes (with heating up time) Detergent concentration: 8 g / l
- the graying inhibitor was added in an amount of 0.5%, based on the test detergent.
- the test vessels each contained 15 g test fabric (5 g polyester, 5 g polyester-cotton blend and 5 g cotton fabric) and 10 g dirt fabric. Cotton dirt from the Krefeld laundry research institute was used as the dirt fabric, namely WFK 10D.
- the detergent used had the following composition:
- Table 2 shows the increase in the reflectance of polyester and polyester / cotton blended fabrics after the addition of 0.5% of the products according to the invention, based on the weight of the detergent used, compared to the washing test without addition and to the addition of a graying inhibitor according to EP-PS 87 671.
- the table shows that, on the one hand, the effect decreases when the polyethylene glycol selected as the starting material for the graft copolymers drops below a molecular weight of approx. 2000, on the other hand, the effect is maximum when the polyethylene glycol / vinyl acetate ratio is approximately 1: 2 to 1: 2.5.
- the copolymers of vinyl acetate described in EP-PS 087 671 are clearly exceeded by the products according to the invention.
- The also shows Table that water-dispersed polyvinyl acetate alone and polyethylene glycol alone has practically no graying-inhibiting effect, as does a graft copolymer whose acetate groups have been completely saponified.
