Description

Use of a composition for the care of fabrics.

Technical field

This invention relates to the use of compositions for the care of fabrics containing polymeric materials for improve the definition of the surface color of a fabric after multiple washes and / or to impart resistance to the formation of balls and fluff on the cloth during washing.

Background and prior art

The washing process generally offers many benefits for the fabric, the most common being the elimination of dirt and stains on the fabric during the wash cycle and the fabric softening during the rinse cycle. However, there are numerous inconveniences related to the repeated use of conventional laundry treatment compositions and / or the washing process itself, one of these being a fairly hard treatment of the fabric during the process of washed.

Fabrics can be damaged by numerous forms as a result of washing and / or repeated use. The formation of fabric balls and loss of surface appearance of the fabric, for example, lint, shrinkage (or expansion), loss of color of the fabric or fade of the color of the fabric (called generally pigment transfer) are some of the Common problems related to repeated washing. These problems can occur simply by hand washing repeated, as well as for a more vigorous machine wash process. Additionally, problems related to fabric damage over time after normal use, such as loss of form and an increased probability of the appearance of wrinkles, they are also significant.

The present invention is directed to alleviate one or more of the problems mentioned above.

The main advantage of the present invention is refers to improving the definition of the surface color of a fabric after multiple washes and / or imparting resistance to formation of balls and fluff on the fabric during washing. The invention may have additional advantages in the treatment of a cloth. For example, other aspects of the appearance can be improved overall fabric, such as a reduction in the trend of the fabric to fold and / or wrinkle.

Washing detergent compositions that contain fabric treatment agents with polyamide-polyamine are described in the document WO98 / 29530. It is claimed that the compositions impart an aspect Global improved to fabrics washed with compositions detergents in terms of surface appearance properties, such as a reduction in pellets / lint and anti-bleaching. In WO97 / 42287 washing compositions are taught which contain treatment agents with polyamide-polyamine of similar types.

Washing compositions containing agents of fabric treatment with polyamide-polyamine may show increased pigment uptake (i.e. increased pigment transfer) and properties of removal of poor stains compared to other compositions of conventional washing.

US5571286 (Connell et al. ) Describes certain polymers and prepolymers derived from polyoxyalkyleneamines and their use in a process to prevent wool shrinkage. Treated wool may also have a softer handling than untreated wool. This document does not mention the treatment of cellulosic fabrics or the problems of loss of the surface appearance of the fabric that they may experience after washing. Additionally, it deals completely with the treatment of wool on an industrial scale, and does not mention the application of fabric compositions in the context of washing processes.

The present invention is based on the surprising finding that certain polymeric materials, including described in document US5571286, can impart an aspect superficial improved to cellulosic fabrics. Polymeric materials may have the additional advantage of side effects reduced adverse, in terms of a pigment transfer increased from poor stain removal, for example, in comparison with certain compositions containing agents of Fabric treatment with polyamide-polyamine.

ΔL ΔE Kenores 1440 at 0.2% -3.47 6.20 Kenores 1440 at 0.1% -1.05 2.32 Polymer A.M 0.93 2.21 Polymer MRSM 0.28 1.47 ΔL = change in clarity ΔE = change in color

Therefore, there is less change in color in the fabric treated with a polymer according to the invention, and therefore less pigment transfer

Example 2 Garment care properties

The measures with Spectroflash (trademark) of a standard test fabric with white and red regions showed that fabrics treated with Polymer AM (brand trade) and with MRSM Polymer (trade mark) according to Example 1 Show reduced damage.

Black area:

ΔL ΔE Without try 9.94 10.07 Polymer A.M 1.81 1.95 Polymer MRSM 3.00 3.09

Red area:

ΔL ΔE Without try 3.30 12.62 Polymer A.M 1.20 5.39 Polymer MRSM 1.19 4.84

In both cases, the treated areas show less changes in the tone that the untreated sample indicated by the lower values of ΔL and ΔE.

Example 3 Stain removal

1 ml of red wine was applied on treated cotton according to the procedure established in Example 1 (5 rinse applications with 0.2% per wash). The spot was measured with a Spectroflash spectrophotometer (trade mark) before washing and after washing at 40 ° C. using Persil Performance Biological powder (trade mark). The change in the color depth of the spots with respect to the sample before washing
it was:

ΔL ΔE Without try -17.93 22.10 Polymer A.M -20.26 23.98 Polymer MRSM -23.36 26.37 Kenores 1440 -19.38 22.37

After washing the color measurements were:

ΔL ΔE Without try -3.97 5.94 Polymer A.M -3.65 5.10 Polymer MRSM -5.70 7.98 Kenores 1440 -8.42 10.45

The Polymer AM (trademark) shows some virtually identical spot release properties in the untreated fabric, while the MRSM Polymer (trade mark) It is between Polymer AM (trade mark) and Kenores 1440 (Commercial brand).

The bottom area of the fabric was also measured to provide an indication of any trend of treatments cause a redeposition of dirt. How much the smaller the spectrophotometer reading, the smaller the change in the color and minor redeposition of dirt.

ΔL Without try -0.20 Polymer A.M -0.02 Polymer MRSM -0.19 Kenores 1440 -0.27 rinse conditioner standard* -0.05 * Comfort (trademark) (Unilever plc, Kingdom United)

Although the differences are small, there are still indications that these polymers do not increase the properties of redeposition of dirt on the fabric in the same magnitude with which PAE type polymers do. In the case of Polymer AM (trademark) there is less redeposition than with the rinse conditioner.

Example 5

With a pad AM Polymer was applied on 2% resinated cotton poplin meters (40 x 40 cm) for give an increase of uptake of 0.5% with respect to the weight of the cloth. Then the meters were machine dried. This led to conducted four times to give a total level of 2% with respect to the weight of the cloth A similar procedure was carried out for the Polymer MRSM and for Kenores 1440. The meters got wet, they squeezed (to simulate the folds of the washing process) and then they were placed in a domestic dryer machine (Miele) with a ballast of moistened cotton sheets (1 kg dry). Then the load dried until the position was reached Anti-wrinkle dryer. The meters were then compared with AATCC softness standards to determine the level of folds. The meters were then ironed and the process of repeated bending
