Description

"Textile treatment composition containing at least one anionic aromatic polyester and at least one nonionic aromatic polyester"

The present invention relates to the technical field of textile treatment, in particular textile cleaning or textile washing.

Detergents contain in addition to the indispensable for the washing process ingredients such as surfactants and builders usually other ingredients that can be summarized under the term washing aids and include such different active ingredients such as foam regulators, grayness inhibitors, soil release agents, bleach, bleach activators and dye transfer inhibitors. Such excipients also include substances whose presence enhances the detergency of surfactants, without them usually having to exhibit a pronounced surfactant behavior itself. Such substances are often referred to as Waschkraftverstärker.

Soil-release agents as a textile treatment agent preclude dirt from attaching directly to the surface of textiles and penetrating the textile material (e.g., textile fiber) where it is difficult to remove. The finishing of the textile surface with so-called soil-release agents causes dirt to build up on the textile surface coated with soil-release agent, thus penetrating or penetrating only in direct contact with this coating but not with the textile fiber itself. By a new washing process, the coating dissolves including dirt

Document WO 98/58044 discloses detergents containing polyesters of terephthalic acid with alkylene oxides in combination with a specific anionic surfactant.

Polymers of ethylene terephthalate and polyethylene oxide terephthalate having a molecular weight of 5000 to 200,000 and their use in liquid detergents are described in German Patent DE 28 57 293.

European patent EP 066 944 relates to textile treatment compositions containing a copolyester of ethylene glycol, polyethylene glycol, aromatic dicarboxylic acid and sulfonated aromatic dicarboxylic acid in certain molar ratios.

WO 2013/139726 relates to single-dose portions comprising liquid detergent compositions provided with a water-soluble coating, said liquid detergents containing a copolymer of ethylene terephthalate and polyethylene oxide terephthalate.

Even without prior equipment of the textile surface with a soil-release agent, it has been found that some soil-release agents can additionally increase the primary detergency of a detergent on selected soils. It got along It has been proven that a soil-release agent does not exert its influence on primary washing power equally across the entire spectrum of soiling.

In particular, the primary detergency is understood to be the removal of stains by a single wash of soiled test materials by a single wash of soiled test materials under standard conditions. The secondary washing power refers u. a. on the extent of graying and incrustation on the textile fiber after repeated washing under standard conditions, for example after 25 or after 50 washes with the detergent selected in each case.

Increasing the primary detergent power gain of the soil-release agents may allow the reduction of the amount of surfactant in detergents. It was therefore the task of increasing the primary washing power of soil-release active ingredients to improve the washing performance of the textile treatment agent. Another object was to lower the surfactant content of textile treatment agents, in particular detergents, without impairing the cleaning performance.

It has now been found that by combining two special soil release polymers (vide infra), the primary detergency of the one soil release polymer specific soils can be increased by the addition of the other soil release polymer, although this other soil release polymer alone, no or only a marginal gain on the primary washing power at the specific soils of one Soil-release polymer achieved. This is particularly observed in greasy soils, especially sebum, machine oil, make-up and shoe polish. Even in the case of unspecified soilings for the soil-release polymers, a synergism of the intensification of the primary washing power was observed by the inventive combination of said special soil-release polymers.

In addition, it has been found that the provision of the present invention effective combination of said polyester soil release polymers in a surfactant-containing textile treatment agent (vide infra) is difficult to accomplish. A combination of said polyesters with surfactants in a clear liquid detergent either leads directly to the addition of the anionic polyester soil release polymer to deposit an insoluble solid or at the latest during storage to cloud the liquid detergent and to solid deposits. It has been found that compositions for use in textile treatment with said polyester combination and surfactants are preferably to be provided as a storage-stable portion which

A substance is liquid according to the definition of the invention if it is present in liquid state at 25 ° C. and 1013 mbar.

A chemical compound is an organic compound when the molecule of the chemical compound contains at least one covalent bond between carbon and hydrogen.

To form a polymer terminus, said valencies of the formula (I) or (IV) and the formula (II) (if present) bind to the structural element of the formula (III) or (V) or to another, monovalent structural element to form an ester linkage ,

The anionic, aromatic polyesters according to the invention are copolyesters which can be formed at least from monomers which, after a polymerization reaction, give corresponding structural units of the formulas (I), (II) and (III) at least in the polymer backbone.

This coarse material can optionally be further ground, for example, in the roll mill or in the screen mill, which can be followed by a sieving and a rounding as described above.

Table 3: Portions

For this purpose, a film M8613 Fa. Monosol (88 μιη) was clamped on a mold with Doppelkavität. The stretched film was heated by contact heating for a period of 2400 ms at 105 ° C and then pulled into the cavity by a vacuum. Subsequently, an appropriate amount of the solid composition of Table 1 was pre-weighed into the first cavity and then the amount of liquid composition L1 of Table 2 was added by syringe into the second cavity. Thereafter, a top film (M8630, 90 μιη) is placed to seal the cavities and heat-sealed (150 ° C, 1000 ms) with the first film. After breaking the vacuum, the portion of the cavity was removed. A wall of the portion's powder chamber was subsequently perforated with a needle. As a result, excess air escaped from the powder chamber of the portion and the film of the wall relaxed.

2.0 washing test

To determine the soil-release performance of the servings, various polyester cloths were first three times with a portion of E1, V1 or V2 in a household washing machine (Miele W 1514) washed with 3.5 kg accompanying laundry at 40 ° C and then provided with grease-containing stains with a diameter of about 2 cm.

Subsequently, a household washing machine (Miele W 1 14) was loaded with 3.5 kg accompanying laundry as well as the soiled polyester cloth rags. In addition, a corresponding portion to be tested was added and washed six times at 40 ° C.

After hanging drying and mangling of the cloth rags, the degree of cleaning of the portions was determined visually. It turned out that the portion E1 according to the invention had a higher degree of purification compared to the non-inventive portions V1 and V2.
