Description

TEXTILE SURFACE MATERIAL FOR CLEANING PURPOSES Description of the Invention Technical Field This invention relates to a textile surface material for cleaning purposes, which has a nonwoven fabric and structures that are enhanced over the nonwoven fabric. Such a surface material is used as a reusable cleaning cloth for wet and dry surface cleaning. STATE OF THE ART Patent document WO 90-14039 discloses a textile surface material consisting of a type of non-woven fibers through which a multiplicity of yarn loops or fiber ends protrude by means of perching. they form continuous surface regions. Patent document WO 94 23634 discloses a cleaning cover consisting of a textile frame incorporating two different cleaning materials. In this case it is a cleaning cover composed of different components with different cleaning characteristics on both sides. The object of the invention is to improve a surface material for cleaning purposes in such a way that the possibilities of using the surface material are improved in a simple manner. DETAILED DESCRIPTION Due to the fact that the structures are arranged on both sides of the surface material, since the structures are in the form of total or partial surfaces, the textile surface material can be used on both sides in the same way, so that that during the use it is not necessary to determine which side you are working with. We speak of a total surface, for example, in the case of velvet on both sides, while the partial surfaces only refer to certain areas of the surface. If the structuring of the basic nonwoven fabric is carried out by mixing simultaneously with a structural hanger, where distances are maintained between the drawings on the opposite side, it is possible to manufacture products with a relatively low surface weight in a simple manner. The lateral distances between the reciprocal structures have for this to be sufficient to avoid a coincidence of the structuring of both sides. The structures that are introduced on both sides can for this be of the same type or even identical. At the same time, given a sufficient separation distance, it is possible to adapt the structures of one of the non-woven fabrics in the unstructured intermediate spaces of the opposite non-woven fabric or, it is glued in such a way that the structures of the two non-woven fabrics overlap. In both cases, a reinforcement of the function during use can be achieved by means of, for example, a brush. Thus, for example, by means of a more accentuated pressure of the unstructured intermediate spaces on the floor, the moisture absorption capacity can be increased, or by the more accentuated pressure of the superposed structures of both non-woven fabrics the cleaning capacity can be increased . However, the glued products have a higher surface weight. In a refinement, the textile surface material has at least two non-woven fabrics bonded to one another, each non-woven fabric being provided unilaterally with structures. For this purpose it is possible to reinforce at least one of the non-woven fabrics with a support material. To reinforce the products, to improve their resistance to breakage, as well as to improve the stability of their shape during use and when washing them, support materials can be used. These support materials may be disposed between the non-woven fabrics or as a layer on a non-woven fabric and / or be disposed within the lamination by bonding two structured non-woven fabrics. As support materials come into consideration nonwoven meshes or other materials, such as webs, fabrics, knitwear, fabrics, the latter preferably with a high content of synthetic fibers (at least 50%), or else they consist entirely of synthetic fibers, preferably polyester (PES). For reinforcement and improvement of the breaking strength, a non-woven mesh or other reinforcement materials such as webs, fabrics, knitwear, synthetic fiber fabrics, preferably polyester, are woven between the layers or as a cover layer. ) with a surface weight of 20 to 60 g / m2. This also improves the stability of the form during use and when washing. Preferably, the base non-woven fabrics are non-woven thermophilabide carded fabrics which can also be reinforced with a perching support material or bonded with a non-woven fabric by thermal binding. Alternatively it is also possible to introduce a support material during the bonding of two non-woven fabrics. The bonding can also be carried out by thermal bonding, for example by the use of non-woven fusible fabrics, or _1 -, -. »,» «By applying a glue. The choice of glue will determine the respective subsequent treatments. As the support material, a non-woven or nappa mesh, or a fabric, knitted fabric or fabric with a synthetic fiber content of at least 50% is considered, since PES and the support material are preferably used as the synthetic fiber. It has a surface weight of 20 to 60 g / m2. In case the non-woven fabric is composed of two layers of different fiber types and fiber characteristics, then it is possible to use both sides for different purposes, for example, one side for cleaning and the other side for drying. In order to be able to work specifically with the structured regions, it is also possible to use a different fiber color. If the basic nonwoven fabric is homogeneous, that is, made of a mixture of fibers that is preferably of fine volume, then with a similar or identical structure perch on both sides, products are obtained which can be used in the same manner as both sides. This is also true if the basic nonwoven fabric consists of two layers of different colors, as long as they are not different as regards the recipes of both fiber blends and the definitions of the individual components, with the exception of the color . The different color in this case only highlights the effect of the structure. In the case where the basic nonwoven fabric, structured on both sides, is composed of two layers with different fiber recipes and / or different definitions of the individual components, then preferably both sides are used for different purposes, example one side for cleaning and the other side for drying. This effect can be reinforced by a different structuring of both sides. In this case the two colors additionally fulfill the function of consigning the modality of use of both sides. In the case of products that are used on both sides in the same way, preferably homogeneously composed, the drying and cleaning capacity can be optimized by the type of structure and by the proportion of structured surface in relation to the surface not structured. It is possible in this way to obtain products that on each side offer the same good cleaning and drying effect. This also applies to products that are composed by the bonding of two individual, structured non-woven fabrics. In order to obtain a structure, that is, transfer the fibers from a horizontal position to a - £ .-: vertical position, a certain fiber mattress is necessary. For this purpose it is already possible to obtain useful structures with a fiber weight of 100 g / m2, preferably the surface material has a surface weight of 150-300 g / m2. With a nonwoven fabric consisting of a thin layer and a coarse layer, wherein the coarse layer constitutes by weight 30 to 50% of the total weight, and consists of 50 to 100% synthetic fibers, preferably polyester (PES) with a volume of 4.2 to 17 dTex, an advantageous range for the cleaning effect is indicated. The use of a coarse fiber influences the cleaning capacity, since the ability to scrub is increased. By the addition of a meltable fiber, preferably of modified polypropylene (PP), which represents 15 to 100% of the total proportion of synthetic fiber, by means of the activation of the meltable fibers by means of temperature an additional agglutination is carried out between the other fibers with respect to the perching. Apart from the bonding with fusible fibers, the greater firmness of the felt material is obtained firstly by the felt needle perching. It works with 80 to 200 stitches / cm2, preferably with 120 to 150 stitches / cm2.

Depending on the intended mode of use, continuous or interrupted longitudinal lists can be produced by the structural needles., as well as interrupted and / or alternating transverse lists, or any other interrupted or continuous patterns, for example letters, whereby it is possible to obtain special cleaning effects. If the coarse nonwoven fabric is perched through the non-woven fabric during structuring, a particular effect results with locally limited scrub areas. By structuring with a stitch depth between 5 and 25 mm, preferably between 5 and 15 mm, by fork or crown needles, pronounced structures are obtained without having to accept a substantial loss of the firmness of the textile material. By melt-bonding the meltable fibers after the production of the structured non-woven fabric, after binding, ligation points are obtained between the other fibers. This achieves a greater reinforcement of the non-woven fabric, in addition to the perching. In the coarse fiber layer it is advantageous that at least 80% of the synthetic fibers have a volume of 4.2 to 6.8 dTex, and that at most 20% of coarser fibers are intermingled. The proportion of at least 40% of absorbent fibers, preferably CV and / or cotton, in at least one layer of the non-woven fabric is of special importance for the beginning of the water absorption process, being that the remaining fibers of fine volumetry they form a non-woven fabric of fine porosity and, through a pronounced capillary effect, they allow a high absorption rate with good water retention. As absorbent fibers, CV will preferably be used in a fine volume range of 1.3 dtex to 2.2 dtex and / or cotton. It is also possible to obtain a surface structure by stamens or threads in the form of loops or open loops, which are inserted into a base material over the entire surface or in partial surfaces. Such products are commercially available for cleaning purposes, preferably unilateral use is contemplated. As the base material, fabrics or knitwear are used, preferably made of synthetic fibers. This base material is inactive in terms of water resource management capacity. However, if a non-woven fabric is used as a base material, preferably homogeneous and reinforced with a support and already heat-set, then for the management of water resources an active material with a high water absorption capacity is available. , very good water retention capacity and that easily releases water when compressed or squeezed. If the structure only extends over partial surfaces and the unstructured surface is in contact with the object to be cleaned, then the drying capacity is significantly increased with respect to the products currently in use, which have to be cleaned and dried with the structure of stamens or threads respectively, being that nevertheless an excellent cleaning power is obtained. The improved drying capacity can be checked by the smallest remaining water film and because the time to complete drying is shorter. In this way it is possible to walk sooner on a cleaned floor. On the other hand, less water is spent due to the greater facility for squeezing the cleaning medium based on non-woven fabric. If two materials of this type are bonded on the basis of non-woven fabrics on the back side, either in such a way that the structures are mutually adapted or overlapped, a product is obtained which can be used in the same way on both sides. Naturally, if necessary, it is also possible to bond unstructured materials, for example with other non-woven fabrics or with structured non-woven fabrics, on the opposite side of a non-woven material which is unilaterally structured with stamens or threads. Products with a yarn or yarn structure on one or two sides of a non-woven fabric have additional advantages over those based on fabrics or knitwear. By means of a specific squeezing or squeezing force it is possible to obtain a specific absorption of water. By means of this it also becomes possible to adapt the emission of water to the object that is being cleaned. In the case of dry dirt stuck initially it will drain less, that is to say, the wettest cleaning medium will be used to dissolve the dirt and, afterwards, after draining strongly, a good drying will be carried out with the same medium. With the means based on fabrics and knitwear can not obtain adequate squeezing effects due to inactivity in the management of the water resources of the base and the lower possibility of elimination of water from the stamens and threads, which proportionally they are present in a higher percentage than in the material based on nonwoven fabric and, therefore, it is not possible to achieve such good drying effects.

In addition it is sufficient to use lower structures and, therefore, less yarn or yarn is used, since the active nonwoven fabric absorbs dirt and water thanks to the high fine porosity, and this much better than stamens or yarns, which in the case of an inactive base, they are isolated for this purpose. In addition, non-woven fabrics return dirt and water more easily than stamens or yarns, there is talk of a higher squeezing effect. Finally, the products based on non-woven fabrics with low structural height have a lower tendency to adhere to the floor than the products with inactive base and higher structures, due to the greater squeezing capacity and the greater resistance to breakage. during use they require less physical effort, which is important mainly for users in the cleaning branch. The stamens or threads can be inserted in the base of non-woven fabric in the form of loops on the entire surface or in longitudinal lists that do not need to be straight, for example zig-zag, by means of the "Tufting" or "tufting" procedure. Mallpol. " These loops can be opened by means of a velvety device. Preferably, the individual components are in the volumetric range between 1.7 dTex and 10 dTex. The proportion of absorption fibers should not be less than 40%. The height of the loops can be between 3 and 12 mm, preferably 5 to 7 mm. Stamens or yarns are preferably within the coarse range of Nml (2xNm2) to Nml2 (2xNm24), preferably within the range of Nm5 (2xNmlO) to Nm8 (2xNml6). Advantageously, the stamens or yarns consist of CV fibers and synthetic fibers, preferably polyester (PES), where up to 50% of the synthetic fibers can be meltable fibers. In the case of yarns or stamens made up of at least 40% absorbent fibers, synthetic fibers, preferably BES, are used, while meltable fibers, preferably PP, whose proportion is 15% to 100% are still being provided. of synthetic fibers. The yarn or thread loops are inserted by means of "Tufting" or "Malipol" procedures. In the case of insertion of tufts of preference a distance between needles is selected between 1. 4 and 2 mm. In the case of partial surface structuring, only the necessary needles are used. The number of stitches per running centimeter is between 25 and 42. The tufted material is preferably coated with an acrylate to reinforce the loops in the back of the material. In the case of sticking two non-woven fabrics, the covering of the back part can be dispensed with. The meltable fibers of the yarn are activated by drying and condensing the coating on the back. By this the yarn or yarn acquires an additional firmness. The somewhat increased stiffening promotes the scrubbing property. If the coating is not applied on the back side, it is necessary to activate the meltable fibers in an additional operation stage. BRIEF DESCRIPTION OF THE DRAWING Exemplary embodiments of the invention are shown in the drawing. A cut through a textile surface material with structures in the form of partial surfaces alternating with each other is shown in Fig. 1, in Fig. 2 a textile surface material of two non-woven fabrics bonded together, in Fig. 3 a textile surface material with structures in the form of a pattern of letters, in Fig. 4 a cut through a surface material of two non-woven glued goods, both of which are reinforced by a material of interposed support, in Fig. 5 an unstructured nonwoven fabric as a starting material, in Fig. 6a a unilateral full-surface velvet manufactured from the nonwoven fabric depicted in Fig. 5, in Fig. 6b a nonwoven fabric with a bilateral velvet in list form, made from the full-surface velvet of Fig. 6a, in Fig. 7a a non-woven fabric with velvet in the form of lists , and in Fig. 7b a nonwoven fabric with bilaterial velvet in the form of lists, with the lists spaced apart. Embodiment of the Invention Fig. 1 depicts a non-woven fabric 1 on whose both sides 2, 3 embossed structures 4, 5 are provided. Structures 4, 5 are configured as partial surfaces and do not overlap each other. However, it is also possible to preset a safety distance that is 10 mm larger than the measurement of the structures on the opposite side. The structures are made by structural perching from both sides, being that the depth of the puncture can vary between 5 and 15 millimeters. The non-woven fabric 1 can be constituted by a non-woven heat-set non-woven material. FIG. 2 shows a surface material of two non-woven fabrics 6, 7, between which a support material 9 is arranged. Each of the non-woven fabrics 6, 7 is provided with structures 8, which independently of each other are also disposed so as to be opposite each other. As an example of another possibility of structuring, a structuring in the form of letters 10 is illustrated in FIG. 3, which are enhanced from the surface 3. A laminated surface material of two non-woven fabrics 11, 12 is shown in FIG. , both non-woven fabrics 11, 12 being reinforced by a support material 13 that is hooked and / or fixed on top. Each nonwoven fabric 11, 12 is provided with structures, specifically yarn loops 14 or yarn open loops 15. If a textile surface material consisting of a homogeneous nonwoven fabric and a nonwoven fabric consisting of two or more layers with different fiber blends is provided with a structure on both sides, then by the structural perching of the surface material only it will be possible to create the alternating structuring shown in Fig. 1. If instead two separate non-woven fabrics are laminated with one another separately, then the structuring can be opposite, as shown in Fig. 2. This would also be possible with a product according to Fig. 4. Through this it is possible to highlight the various optical and functional effects. In Figs. 5-7 show the fabrication of a surface material structured on both sides, from an unstructured nonwoven fabric 16. From the non-woven fabric 16, a unilateral velvet 17 of full surface is produced in FIG. 6a by means of a fully-equipped needle board. The material thus processed is turned after the first step through the processing machine, so that the full-surface velvet 17 rests on top. The return of the velvet to the opposite side is then carried out in the form of lists by means of a table of needles which, in the direction of production, is equipped with needles formed by bands. By this, the lists 18 shown in FIG. 6 are created. In Fig. 7a, from the non-woven non-woven fabric 16, a velvet is produced in the form of lists by a needle board which in the production direction is equipped with needles forming bands. Unlike what is shown in Fig. 6a, in this case there is no full-surface velvet, but soon a velvet in the form of lists, being that between the lists 19 a diatanciamiento is maintained, within which it is possible to intersperse another list. Again the material thus obtained is turned after the first step through the processing machine. The insertion of the velvet on the opposite side to the center between the two velvet lists 19 produced in the first pass is carried out with the same table with input of the material in displaced phase, or with a table equipped with bands of needles in displaced phase. In both cases it is necessary to guide the material with precision to avoid lateral deviations. Preferably, a minimum lateral distance of 3 mm will be necessary between the opposite velvet lists 19, 20, in order to avoid overperfolding. In the case of the surface material according to Fig. 6b, the structures of both sides adjoin each other without intervening spaces. By Thus, the sum of the structured surfaces of both sides corresponds to the starting surface of the unilateral full-face velvet. In accordance with the drawing it is possible to specifically divide the structured surfaces between both sides. It is also possible to take back other structures from the velvet side to the opposite side, specifically as velvet with a machine for perching Di-Lour structures, or in the form of loops with the perching machine of Di-Loop structures. The surface material according to Fig. 7b may have different width lists, but nevertheless, starting from Fig. 7a, it is also possible to insert a structure on the opposite side between the velvet lists 19 as shown in Figs. 1 to 3, specifically as velvet or in the form of loops. In the case of this surface material the whole of the bilaterally structured surface is always smaller than the surface of a material one, since between the drawings of the opposite sides it is necessary to maintain a lateral distance of security to avoid over-perching. According to this method, the proportion of the structure with respect to the overall surface and on the side can be varied widely by the selection of the drawings and the size of the distance between the drawing sections extending on opposite sides.
