Description

The present invention relates to a textile structure which comprises a textile base material, wherein the textile base material is mechanically, thermally and / or chemically solidified. The textile structure is a cleaning textile.

It is known in the prior art to coat and / or solidify textile structures whose base material consists, for example, of a nonwoven fabric, on one or both sides. In this way, among other cleaning textiles can be formed, which have better cleaning properties compared to uncoated textile materials. In addition, other properties of the textile structures, such as their durability, softness and / or absorbency can be influenced.

From the publication DE 10 2005 038 170 B4 is a cleaning fabric based on a textile fabric for cleaning preferably heavily soiled surfaces in the wet, damp and / or dry area known, the sheet wholly or partly consists of melamine fibers and / or melamine fibers. From the melamine fibers and / or melamine fibers, woven, knitted or crocheted fabrics, nonwovens, braids or tufted goods can be produced, and melamine fibers can advantageously also be formed into a fabric in a mixture with synthetic fibers or natural fibers.

Through the use of melamine fibers or threads in a textile material, cleaning textiles can be made available which, compared with conventional cleaning textiles, have an improved degree of cleaning of the surfaces, in particular for the removal of particularly intensive or pronounced soiling, and good handling.

The in the publication DE 10 2005 038 170 B4 For example, cleaning fabric described can be made from basefilm fibers formed from melamine resin. Although such fibers are commercially readily available but also relatively expensive and thus lead to an increased price of the final product. Accordingly, such cleaning textiles are not as inexpensive as other, simpler designed cleaning materials produced.

Also known in the art are sponges of melamine foam for cleaning heavily soiled articles or surfaces. Although these sponges achieve a very good cleaning effect, but have the disadvantage that they have a high abrasive effect on the surface to be cleaned. For example, if such sponges are used, scratches may appear on the cleaned surface.

It is therefore the object of the present invention to provide a textile structure with which a very good cleaning effect can be achieved and which nevertheless allows a gentle cleaning of objects or surfaces. In addition, the textile structure should be as inexpensive to produce.

This object is achieved on the one hand by a textile structure of the abovementioned type, wherein at least one side of the textile base material has a coating / impregnation, prepared from a melamine-containing dispersion or a melamine-containing polymer solution.

Since the textile structure according to the invention has a textile base material which can be provided inexpensively in a wide variety of designs and colors, the textile base material can be coated both on one side and on both sides with the melamine-containing dispersion or the melamine-containing polymer solution, a textile structure which can be produced cost-effectively be provided with variable optics. The melamine-containing coating of the textile base material furthermore leads to a significantly improved cleaning action of objects or surfaces compared to conventional cleaning materials. In this case, the melamine concentration of the applied dispersion or polymer solution can optionally be adapted to the intended application of the textile structure. The melamine-containing coating material proposed according to the invention can furthermore be easily and effectively applied to the textile base material in various ways, so that the textile structure according to the invention can be produced both for special individual applications and mass-produced.

According to an advantageous embodiment of the present invention, the dispersion of binder, fixer and melamine powder is formed. Thus, at least one side of the textile material can be treated with a dispersion containing melamine powder. The melamine powder used is pure, finely divided powder. It is possible, depending on the field of application of the textile structure according to the invention, to select the ratio of binder, fixer and melamine powder accordingly. The melamine powder has melamine particles which can be distributed homogeneously in the dispersion. In this way, a melamine-containing coating with homogeneous properties for impregnation of the textile base material can be formed.

In a preferred embodiment of the present invention, the dispersion is foamed or a paste. Accordingly, the treatment of at least one side of the textile material with melamine powder-containing foam or by means of a paste or in the form of a solution can be carried out using the customary application methods. The melamine-containing foam or the melamine-containing paste can be produced in a simple manner using melamine powder and can be applied particularly well to the textile base material.

In a favorable example of the invention, the coating has a portion penetrated into the textile base material and a cover layer on the textile base material. This ensures that the impregnation is firmly connected to the textile base material, wherein the cover layer, regardless of the material type of the base material, can be adjusted in their properties.

It is particularly advantageous if at least one side of the textile base material is solidified with a binder, for example based on acrylate. Hereby, in addition, a good chemical solidification of the textile base material can be achieved.

For example, the textile base material may be a nonwoven fabric, a woven fabric, a knitted fabric, a knitted fabric, a braid or a tufted product. Such materials are easy to prepare, readily available commercially and can be used according to the invention in a wide variety of embodiments. This creates a high variability with regard to the concrete design and application of the textile structure according to the invention.

According to a preferred embodiment of the present invention, the textile base material is made of viscose, polyvinyl alcohol or polytetrafluoroethylene or a mixture of at least one of these materials with at least one other material. Viscose is used as a textile base material for the textile structure, this can be provided with a particularly good softness and absorbency.

A textile base material based on polyvinyl alcohol (PVA), which is provided on one side with the coating according to the invention, has proved to be particularly advantageous. It significantly increases the cleaning effect without the known properties, such as water absorption, dirt absorption, etc. to deteriorate.

If polytetrafluoroethylene (PTFE) is used as the textile base material, this essentially shows no adhesion of dirt particles.

If viscose, polyvinyl alcohol or polytetrafluoroethylene is mixed with another material, additional effects can be achieved.

For example, in addition to the textile base material, the mixture may comprise fibers of at least one organic polymer material, preferably of polyolefin, polyamide or polyester. By adding polyester, polyolefins or polyamides to the textile base material, an increase in strength of the textile base material can be achieved. Furthermore, with the use of organic polymers, an additional thermal fixation of the textile base material can take place as a result of a melting of the fibers by the action of temperature, wherein the molten polymer material acts as an adhesive between the fibers of the textile base material.

According to a further suitable embodiment variant of the invention, the mixture comprises melamine fibers in addition to the fibers of the textile base material. As a result, a textile structure with improved polishing effect can already be provided by the base material.

Due to the advantageous properties of the textile structure according to the invention, their use as a cleaning textile is recommended. Thus, for example, wiping or cleaning cloths can be made of the material of the textile structure according to the invention, but in principle the use of the textile structure according to the invention is variable.

According to one embodiment of the invention, a printing pattern of abrasive is applied to the coated with the dispersion or the polymer solution side of the textile structure. The abrasive can be applied in a simple printing process in a variety of variants on the textile structure. Thus, an additional cleaning effect as well as a decorative effect for the textile structure can be achieved.

The textile structure can be produced by a process in which a textile base material is mechanically thermally and / or chemically solidified and wherein a melamine-containing dispersion prepared or a melamine-containing polymer solution is provided, and at least one side of the textile base material with the dispersion or the polymer solution is coated.

With the method, a textile structure can be produced in a simple and highly productive manner, which has a melamine-containing coating on one or both sides. The melamine-containing coating can penetrate into the textile base material, as a result of which it is firmly bound into the textile base material. The textile produced in this way Due to the advantageous cleaning effect of the melamine-containing coating, the structure can be used, for example, as a cleaning textile.

According to an advantageous embodiment, the dispersion is prepared from binder, fixer and melamine powder. The dispersion prepared from binder, fixer and melamine powder can be foamed in a simple manner using a blender, resulting in a foam containing melamine powder, which is advantageously applied as a coating to the textile base material.

According to a particularly favorable embodiment variant, the dispersion is foamed or formed as a paste. In this case, the dispersion or the paste can be prepared with proportions of melamine powder and easily applied to the base material with a desired thickness.

Preferably, at least one side of the textile base material is coated or impregnated with an acrylate binder. Due to the acrylate binder, the textile base material can be easily and permanently chemically solidified. Instead of an acrylate binder, another suitable binder, such as a polyurethane material, vinyl chloride or vinylidene chloride, etc., may be used.

In addition, it has proved to be advantageous if the side of the textile structure coated with the melamine-containing dispersion or the melamine-containing polymer solution is additionally coated with a binder. In this way, the abrasion resistance of the melamine-coated side of the textile structure can be increased and a better integration of the applied melamine-containing, in particular melamine powder-containing dispersion or the melamine-containing polymer solution into the textile structure can be realized.

In a particularly preferred example, the textile base material is coated at the same time and on both sides of a plant. Thus, the binder and / or the melamine-containing or melamine powder-containing coating can be applied in one operation to the textile base material, whereby a particularly high efficiency in the production of the textile structure is achieved.

In a favorable embodiment, the dispersion or the polymer solution is applied to the textile base material in a rotary stencil process. In this method, a doctor blade is provided in a tubular stencil device, with which, for example, melamine powder-containing foam is pressed out on both sides of the rotating during application tube template, whereby a uniform and continuous coating of the textile base material can be done.

A particularly good durability of the melamine-containing foam on the textile base material is achieved when the textile base material coated with the dispersion or the polymer solution is dried at about 130 ° C. to about 150 ° C. At this temperature, which is preferably realized by introducing the coated textile base material into a furnace, not only a drying of the foam but also a long-lasting fixation of the impregnation on the textile base material can be achieved.

In a likewise favorable development, the melamine-containing dispersion or the melamine-containing polymer solution is applied to the textile material in a padding process, a doctor blade method, a spray application, a trowel, with a slot die or a slot die and optionally dried at elevated temperature.

Advantageous embodiments of the invention, their properties, function and advantages are explained in more detail below with reference to the figures of the drawing, wherein

1 schematically shows an embodiment of a textile structure according to the invention 11 in a sectioned side view. The textile structure 11 has a textile base material 1 which is a nonwoven fabric in the embodiment shown. When using a nonwoven fabric as a textile base material 1 for the textile structure 11 Both a nonwoven fabric and a filament nonwoven fabric can be used. In other, not shown embodiments of the present invention may also be another textile base material 1 , such as a woven, knitted or knitted fabric, a braid or a tufted fabric may be used. The textile base material 1 serves as the base material of the textile structure 11 , The textile base material 1 For example, it may be 100% viscose having a fiber count in a range of about 0.8 dtex to about 7.0 dtex, preferably from about 1.7 dtex to about 3.3 dtex, and a fiber length of about 15 mm to about 100 mm , preferably from about 30 mm to about 60 mm, be formed. Such a material is characterized by particular softness and absorbency.

In addition, however, it is also possible that the base material is made of viscose, polyvinyl alcohol (PVA) or polytetrafluoroethylene (PTFE) with admixture with other materials such as an organic polymer material such as polyolefin (eg polypropylene), polyamide or polyester. Thus, in the blend, polyester or polypropylene may be incorporated at about 5% to about 50%, preferably about 12% to about 20%. Materials such as polyester or polypropylene lead to an increase in strength of the textile base material 1 , Furthermore, it is possible by melting a mixed organic polymer material, an additional thermal fixation of the textile base material 1 to achieve, wherein the molten material acts as an adhesive between the textile base material, such as the viscose.

For example, becomes a textile base material 1 formed with viscose fibers with the addition of other fibers, such as polyester, polypropylene or polyvinyl alcohol fibers, it has proved to be advantageous if the polyester or polypropylene fibers have a fiber fineness in a range from about 1.0 dtex to about 5.5 dtex , preferably from about 2.2 dtex to about 4.4 dtex, and having fiber lengths in a range from about 15 mm to about 100 mm, preferably from about 40 mm to about 76 mm.

In another embodiment of the invention, the textile base material 1 also be formed from a mixture with melamine fibers. By incorporating melamine in the form of fibers, for example in a nonwoven fabric of viscose, can increase the polishing effect of the textile structure 11 be achieved. Furthermore, this results in the possibility of the textile structure 11 For example, to use for polishing hot materials, since melamine is particularly well suited as fire protection material. Furthermore, for example, grilled gloves, refractory lining fabrics, fire blankets or filter media based on the textile structure of the invention 11 getting produced.

On a first page 21 of the textile base material 1 the textile structure 11 out 1 is a binder layer 2 intended. The binder layer used here 2 is made of acrylate and serves for one-sided chemical solidification of the textile structure 11 , When using a binder course 2 However, one is not on the in the embodiment of 1 used Acrylatbindermaterial limited. For example, other binders such as polyurethane, vinyl chloride or vinylidene chloride can also be used.

On the other, second page 22 has the textile structure 11 of the embodiment 1 an impregnation of a foamed melamine-containing dispersion 3 or a melamine-containing foam. The melamine-containing foam is essentially a plastic dispersion which is mixed with fillers. In the example shown, the melamine-containing dispersion 3 formed from a mixture of binder, fixer and melamine powder. The percentage composition of the material mixture can vary greatly. As binder, for example, an acrylate binder can be used. However, other binder materials may be used in other embodiments of the invention. Instead of the dispersion 3 It is also possible to use a melamine-containing polymer solution.

The melamine powder-containing dispersion 3 is foamed by a blender and can with the help of various application methods on the textile base material 1 be applied. The melamine powder-containing dispersion 3 can also be formed as a paste and on the textile base material 1 be applied. For example, as in 5 shown, the melamine powder-containing foam using a rotary stencil device 8th one or more sides on the textile base material 1 wherein the rotary stencil device comprises at least one rotatable, sieve-like tube arrangement 6 in which a squeegee 7 is arranged, with which on both sides of the pipe assembly 6 the foamed, melamine powder-containing dispersion 3 from the pipe arrangement 6 can be pushed out.

As an application method for the foam dispersion 3 but can also be another method, such as the padding method, are used. Further suitable coating methods for application of the melamine-containing coating to the textile structure according to the invention are also doctor blade methods, spray application methods, patting or application methods with slot die or slot die.

The foam application of the melamine powder-containing dispersion 3 can be varied within a wide range. A dry application rate of about 25 g / m ^{2 has} proved to be advantageous.

After applying the melamine-containing foam to the textile base material 1 the foam-coated arrangement is dried. Drying may be done in an oven at about 130 ° C to about 150 ° C. At this temperature, the melamine-containing foam is particularly good on the textile base material 1 fixed.

2 schematically shows another possible embodiment of a textile structure according to the invention 12 in a sectioned side view. The textile structure 12 is essentially similar to the textile structure 11 out 1 formed, wherein like reference numerals designate like features of the structures and according to the comments on these features with regard to 1 is referenced.

At the textile structure 12 indicates the melamine powder-containing dispersion coating 3 the textile structure 12 one in the textile base material 1 Invaded share 31 and one on the textile base material 1 remaining cover layer 32 on. Such an arrangement results, for example, after the drying process or after a lax exposure time of the melamine powder-containing foam on the textile base material 1 ,

3 schematically shows yet another possible embodiment of a textile structure according to the invention 13 in a sectioned side view. Again, the same reference numerals as in the 1 and 2 same features of the structures. Accordingly, reference is also made here to the above statements on these features.

At the textile structure 13 is on the foamed, melamine powder-containing dispersion 3 a binder layer 4 , such as an acrylate binder layer, applied. The additional coating of the melamine powder-containing impregnation by the binder material can increase the abrasion resistance of the textile structure 13 and a better integration of the applied melamine-containing foam layer or dispersion 3 in the textile structure 13 will be realized.

4 schematically shows yet another possible embodiment of a textile structure according to the invention 14 in a sectioned side view. Again, the same reference numerals as in the 1 to 3 same features of the structure. For this purpose, reference is also made to the above comments on these features.

The textile structure 14 indicates an additional print pattern on the melamine powder-containing coating 5 from scouring up. The print pattern 5 can be found in a variety of structural variations on the surface of the melamine-containing dispersion coating 3 the textile structure 14 be provided. By the scouring agent from which the print pattern 5 is formed, the textile structure 14 be given an even better cleaning performance.

It should again be emphasized that the in the 1 to 5 shown embodiments of the inventive textile structure 11 . 12 . 13 . 14 are merely exemplified, with numerous modifications of the textile structure of the invention as well as the corresponding method for their preparation are possible. As already indicated, the coating with the melamine powder-containing foam dispersion or paste or the application of a melamine-containing polymer solution for impregnating the textile structure according to the invention can be carried out both on one side and on both sides.

The textile structure according to the invention is particularly suitable as a cleaning textile. For example, this can be used to make household and industrial cleaning wipes. However, as already explained above, in particular due to the high heat resistance of the melamine constituents of the textile structure, additional fields of application for the textile structure according to the invention can also be found, in which their heat resistance is of interest.

Typically, for example, cleaning wipes having a size of about 40 × 40 cm could be formed at a basis weight of about 110 g / m ² to about 230 g / m ² . Here you are, however, completely free in terms of design options.

With the textile structure according to the invention and the associated method cleaning wipes can be produced, which have a significantly improved cleaning performance compared to standard cleaning wipes. In comparison to melamine foam, these have a less pronounced abrasive effect. In addition, stand out the textile structures produced according to the invention by their simple and inexpensive manufacturability.
