Description

Agent intended for the inhibitor sizing of dirt for textile surfaces.

The invention relates to an agent intended for prepared dirt inhibitor for textile surfaces, in Particular for textile floor coverings.

Known agents intended for sizing dirt inhibitor, eg of carpeted floor, are used to retard the renewed fouling of carpeted floors, in particular after a treatment thereof with an agent for carpet cleaning. Such agents intended to delay the fouling are usually based on a resin fluorocarbon, and are sprayed in liquid form on the surface to be squeezed, and after this they are applied by rubbing and they are distributed with a brushing device or a similar one. In this case, the fact that the agent, sprayed eg with usual spray bottles in the domestic sector, It cannot be distributed evenly. Nor the incorporation with a brushing device achieves a uniform distribution. The liquid which contains the agent is not contacted by the bristles with each of the fibers of the textile floor covering. In addition to this, by spraying the agent the surrounding environment becomes dirty, such such as skirting boards, furniture, hard floor, etc.

From the patent application document European EP-A-0392248 is known a cleaning agent, which has a support material based on swollen polymer particles, with a high capacity of absorption, and organic fiber particles.

Starting from the state of the art cited to In principle, the invention is based on the mission of presenting a agent intended for dirt inhibitor sizing for textile surfaces that, with simplified handling, allow avoid fouling of the environment.

The problem posed by this mission is solved for the purpose of claim 1. The substance solution active may contain a fluorocarbon resin or a derivative of polysiloxane, or additionally alternatively a combination based on a formulation of fluorocarbon resin and a derivative of polysiloxane. As a consequence of the composition according to invention, the solution of dirt-inhibiting active substance, such as a fluorocarbon resin, it is applied through a intermediate support, such as cellulose or others known support materials. The agent according to the invention is spread very simply on the textile lining of floors, to be squeezed, and after that it is incorporated, e.g. by means of a brushing device in the floor covering. In In this case, fouling of the environment is avoided. An advantage Additional composition according to the invention is the behavior Improved fouling against the usual agents dirt inhibitors It follows that, after a cleaning of the textile floor covering, the degree is decreased of fouling essentially correspondingly, so that, after cleaning, a degree of fouling is achieved, corresponding to that of a soil treated with a cleaning agent habitual. In order to further increase the cleaning effect, it may be provided that the agent also contains an agent for the cleaning of textile materials, which preferably contains a surfactant or a mixture of surfactants. In this case can be an anionic, nonionic surfactant, cationic or even amphoteric, the surfactants being anionic, however, more effective for the cleaning effect than nonionic or amphoteric surfactants. In this context, the composition according to the invention, with such a support material as cellulose It manifests itself as advantageous in the sense that active substances, deposited next to it, remain effective. It is known that anti-dirt products (in English anti-soil) intended to inhibit dirt, which contain cationic particles, are not compatible with anionic surfactants for cleaning. These they are neutralized in solutions and become ineffective. Both active substances need their electrical charge, to enter contact, on the one hand, with the fibers of the carpet (anti-soil; dirt inhibitor agent) and, by other part, with the dirt (surfactant, agent cleaning). The support material, in particular cellulose, has a diverse affinity for the respective components, which by consequently they are absorbed by the support material in diverse concentration, and are deposited next to the fibers in the Exterior. Therefore, cationic and anionic particles are not neutralize, after which both components remain effective through the support material that acts as a catalyst. In a preferred embodiment of the object of the invention, the support material is mixed with water, being made in addition to a mixture of organic fiber particles, deposited next to the surface of the polymer particles saturated with water, it is provided with a solution of active substance. As support material, for example, particles are used polymeric, very absorbent, swollen after this - the called superabsorbent materials - and this in common with organic fiber particles, which are deposited next to the surface of polymer particles. Polymer particles very absorbent and swollen, they provide the necessary volume and necessary area by means of a high proportion of fixed water in polymeric particles. The support material, or the absorbent material, is entirely available to the surface of the carpet This tends to the formation of an agglomerate, of such way that Aenarena is not on the carpet. Fiber particles organic are deposited next to the surface of the particles swollen polymers. Therefore, they are very well distributed and only a small amount of fiber particles is needed organic. An additional essential advantage has to be seen in the fact that very variable formulations are possible, in particular of the dirt inhibitor substance. For example, in this regard, formulations of fluorocarbon resins may be used and / or polysiloxane derivatives as inhibitors of dirt in connection with an intermediate support of the type mentioned. In a further embodiment it is provided that the particles Polymers consist of a polyacrylate. It is especially preferred a crosslinked poly (acrylic acid), which is partially presented Like a sodium salt Such highly absorbent polymers can collect a multiple of your own weight of aqueous liquids. In this case, a gel is formed, the structure of which can be, however, diverse. Such highly active polymers in absorption do not give off the aqueous liquid, that is as a rule the normal water that they have absorbed, not even under pressure, or just do it in a relatively small part. In the context of the invention, it is preferred that the gel has the structure of a granular mass (structure of caviar). In this way polymer particles are formed very small, spherical structure, with a diameter of approximately 10-1,000 µm in the swollen state. By way of correspondingly, a very large surface is established. Fibers organic can have a diameter of 5-30 µm and a length of 50-400 µm. In this case it is preferably cellulose fibers. For the rest, they can be provided usual auxiliary and odoriferous substances, such as preservative agents, an antistatic agent, etc.

With regard to the recipe of the material of support is referred to the European patent document EP-B1 0.392.248.

The agent according to the invention is explained more in detail below with the help of the attached drawings, which they represent only some examples of embodiment of the agent. There show:

Fig. 1 a diagram for the representation of renewed fouling of carpeted flooring;

Fig. 2 a bar chart for the representation of cleaning and fouling behavior on a carpeted floor made of polyamide velvet;

Fig. 3 a corresponding bar chart to that of Fig. 2 with an agent according to the invention in a form Additional realization.

The diagram shown in Fig. 1 shows the renewed fouling behavior of carpeted floor without treat (line U), of a carpeted floor treated with a habitual carpet cleaning agent (line H), of a floor carpeting treated with a usual active substance solution that it contains a dirt-inhibiting substance (line W) and a carpeted floor treated with an agent (WT line) consisting of a dirt-inhibiting substance and in a material of support.

A mixture, presented by way of example of WT agent, may in this case consist of:

65 parts of one active substance solution (dirt inhibitor such as, for example, a fluorocarbon resin)

35 parts of a support material (e.g. cellulose)

From the diagram represented in Fig. 1 it can be recognized that, in particular, compared to usual W dirt-inhibiting agents, applied in a liquid form, the WT dirt inhibitor agent, provided with a support material, according to the invention, inhibits better throughout a period of time of several weeks the renewed fouling of the carpeted floor treated. Thus, the degree of fouling delta E of the WT solution corresponds, over a first period of fouling time A ', approximately to the degree of the solution Known W multiplied by a factor 0.5 to 0.8. after one first cleaning R ', with the WT agent approximately degree of fouling delta E, which corresponds to that of a soil carpeting treated with a regular cleaning agent H.

As the bar chart in Fig. 2, the fouling behavior of a carpeted floor, treated with a WT agent, it has been essentially improved with respect to that of a soil, treated with a usual agent W inhibitor of dirt. In particular, after several fouling phases (A 'to A' '' ') and several cleaning phases (R' to R '' '') are They show some manifest differences.

By essentially fouling decreased, also the degree of fouling delta E decreases correspondingly essentially after cleaning (R ' up to R '' ''), so that after a cleaning is reached a degree of fouling delta E, which corresponds to that of a soil treated with a usual cleaning agent H.

In order to further increase the effect of cleaning, the WT agent may be provided with other agents surfactants Thus, a mixture presented by way of example WT ' It can consist of:
