Description

Cleaning cloth {CLEANING CLOTH}

The present invention relates to a cleaning cloth comprising a textile based material and a coating / impregnation thereon. The cleaning cloth exhibits a novel combination of excellent gliding properties and excellent cleaning properties. Wash cloths are also highly effective against both hydrophilic and hydrophobic contaminants.

Various types of cleaning cloths for household or professional cleaning of flooring or other surfaces are known. The cleaning cloth may have a simple structure by being formed of a main body, for example, a single-layer textile. It is an important requirement for cleaning cloths to efficiently absorb and wash contaminants from the surface and to completely re-emit as much as possible during the wringing operation. The ability to absorb and release water is an additional important requirement of the wash cloth. Not only is water required to remove stuck contaminants, but it is also used to combine debris, such as dust, that have been detached and / or contaminants before removing the fabric from the surface to be cleaned. The gliding properties for some of the fabrics are additionally important to the user. It should be noted that when used to clean a large area of cleaning cloth (eg, windows, blackboards, large tables, walls, automotive bodywork), it must tend to glide easily to achieve good ergonomics and low power consumption during wiping It is because it is revealed. In contrast, in the case of smaller or more highly contaminated areas, the user is generally more likely to be able to remove stuck contaminants and / or the cleaning cloth may also exhibit higher friction than the cleaning cloth to provide haptic feedback .

It is known to provide coating / impregnation of textile based materials for improved cleaning performance. Polyurethane (PU) coating / impregnation may be provided, for example, in textile materials. These PU coating / impregnating materials are generally applied by dipping the substrate into a solution of PU and dimethylformamide (DMF).

In a further known process, a textile-based material composed of PVA (polyvinyl alcohol) fibers is coated / impregnated with PVF microfoam. Good adhesion between the fibers and the coating / impregnating material is achieved because the surface of the fibers is initially dissolved in the aqueous medium during the coating / impregnation process to ensure durability and washfastness washing-fastness chemical-physical surface-type bonds.

It is an object of the present invention to provide a cleaning cloth of the type mentioned in the introduction which combines excellent gliding and water-absorbing properties and excellent cleaning properties, while exhibiting excellent fastness to washing. A very good cleaning effect should be achievable with an additional cleaning cloth. More particularly, the cleaning cloth must be effective to absorb both hydrophilic and hydrophobic contaminants at the surface to be cleaned.

The cleaning cloth should be able to re-emit the contaminants absorbed, especially contaminants, easily and efficiently during rinsing.

This prevents, for example, absorbed sand (e.g., made of quartz pieces) from scratching or damaging a chromed / polished surface during its cleaning. The cleaning cloth should additionally be useful for weak cleaning of the article or surface. Finally, the coating / impregnation should exhibit sufficient adhesion to the textile-based material during cleaning, more particularly to ensure the corresponding mechanical stability in mechanical laundering. The high stability in mechanical washing can be achieved in the context of the present invention in the context of the present invention by using 7 g of Eltra detergent / disinfectant, a sterilization temperature of 60 ° C, a treatment time of 20 minutes, a liquor ratio of 5: 1 and an AB target activity As used herein means that the weight loss of the wash cloth is less than 5 wt% in the Eltra wash, as defined in Bundesgesundheitsblatt - Gesundheitsschutz - Gesundheitsschutz 10, 2007, page 1345.

This object is achieved by a cleaning cloth comprising a textile-based material comprising continuous fibers comprising a hydrophobic material, in particular a continuous microfilament, according to the invention, wherein the textile-based material has a PVF foam, in particular a PVF microfoam And an area that does not have a PVF foam, and in particular does not have a PVF microfoam. The PVF foam can be present by coating and / or impregnation.

The cleaning cloth of the present invention is characterized by a hydrophobic-based material comprising a region having PVF foam, in particular a region having PVF microfoam, but also a region not having PVF foam, in particular having no PVF microfoam. Advantageously, the non-PVF foam region is uncoated / non-impregnated. PVF (polyvinylformal) foam can be formed by the reaction of formaldehyde and PVA, as those skilled in the art will appreciate. This reduces the water solubility of PVA. For the purposes of the present invention, the PVA foam preferably has a water solubility of less than 5 wt% at 100 < 0 > C.

The textile-based material preferably consists of at least some microfibers. It is particularly preferred that the textile-based material is composed of microfibers up to about 60 wt%, more preferably from about 80 wt% to about 100 wt%. However, in textile-based materials that are hydrophobic, and thus oleophilic, the fibers have high water absorption (e.g., dry weight percent of the fabric) due to the capillary action of the knitted microfiber yarn. Nevertheless, because of the lipophilicity of microfibrous materials, amphiphilic products can be obtained by combining with hydrophilic PVF foams.

Complete coating / impregnation of microfibrous-based materials with PU greatly reduces water absorption, for example, because the PU layer has the effect of significantly inhibiting capillary action. In contrast, partial coating / impregnation with PVF foam by the method of the present invention, if so, reduces water absorption to only a minor extent. At the same time, good rinseability of the contaminants absorbed from the fabric is obtained.

A further advantage of the cleaning cloth according to the present invention is that it is totally amphipathic, including hydrophobic materials in the form of fibers, including hydrophobic materials combined with a cleaning cloth hydrophilic material (PVF foam). This is a reason why the cleaning transition of the present invention has a high cleaning effect on both lipophilic and hydrophilic contaminants, which enables a very wide variety of applications.

The cleaning cloth of the present invention has a further excellent level of wash-fastness. This is surprising because until now it has always been assumed that coating / impregnation of PVA fibers into the PVA solution is required for high fastness properties. The chemical similarity of the two materials also leads to good chemical and mechanical bonding between the fibers and microfoam to some extent due to partial dissolution of the PVA surface of the fibers. However, in current practice tests, non-PVF based materials, such as PP / PES / PA, have also been shown to be able to form good bonds with PVA foam structures, especially wash-fastness bonds.

The use of PVF is further advantageous in that PVF is itself particularly absorbent due to the free OH groups. The hydrophilicity of the PVF material can be further increased by using it in the form of a microfoam. Such microfoam preferably has a pore size of less than 100 [mu] m. These materials have a much higher degree of hydrophilicity due to the micropores of the microfoam structure. The PVF microfoam can additionally accommodate the yarns of the fibers, and optionally the textile-based material, to a fairly or even to a complete extent, thus making it possible to achieve stable mechanical bonding between the base material and the coating / impregnation. This is advantageous in that the PVF microfoam actually does not have good adhesion to the hydrophobic fibers of the base material.

In an alternative embodiment of the present invention, it is an object of the present invention to provide a cleaning cloth comprising a textile-based material comprising continuous micro filaments comprising a hydrophobic material, in particular a hydrophobic material, comprising a PVF foam, Foam is provided to at least a portion of the textile-based material, and the PVF foam is less than or equal to 50 wt%, preferably less than or equal to 30 wt% of the total weight of the wash cloth. In actual testing, this cleaning cloth has been proven to have similarly amphipathic characteristics due to the fractional PVF foam in the wash cloth.

For the purposes of the present invention, it is particularly preferred that the base material comprising microfibers, in particular interlooped fabrics, is combined with a PVF microfoam. Advantageous is that the protruding microfibers continue to provide excellent cleaning performance against oily contaminants, particularly at the same time, the PVF microfoam does not reduce to some extent the inherently superior water absorption of microfibrous-based materials. Also, in this embodiment, the absorbed particles of the contaminant are washed out.

The use of a base material in the form of a knitted fabric has the effect of further improving high wash-fastness, since the knitted-based material has the original high level of wash-fastness due to the spatial interconnection of the yarn.

In practical tests, the basis weight of PVF coating and / or impregnation has advantageously been demonstrated to be in the range of 10 to 150 g / m ² , preferably 50 to 100 g / m ² . The basis weight of the textile-based material advantageously ranges from 100 to 250 g / m ² , preferably from 150 to 200 g / m ² .

The textile-based material of the present invention is based on fibers comprising hydrophobic materials. The term "hydrophobic" as used in the present invention should be understood to have a typical meaning. More particularly, for the purposes of the present invention, a material that is considered hydrophobic has a contact angle of at least 90 DEG with respect to water on the surface of the compression body formed from the material. As will be appreciated, the contact angle can be, for example,

Can be measured using an angular angle measuring tool from < RTI ID = 0.0 > It has been found that fibers, especially micro fibers, containing or consisting of the following materials are particularly suitable: polyamides or polyesters, hydrophobized viscose, modified polyesters, polyester blended fabrics, polyamide blended fabrics, Nitriles, triacetates, acetates, polycarbonates, polyolefins such as polyethylene and polypropylene, polyvinyl chloride, glass fibers and / or mixtures thereof. The invention is particularly preferred when using polyamides, especially nylon-6 or -6,6, polyethylene and / or polyester, especially PET and / or mixtures thereof. The present invention is preferred when using a mixture of PET and polyamides, especially PA6 and / or PA66, preferably PET: polyamide ratios of 70:30 to 30:70.

Staple fibers and / or continuous filaments are preferred. In one preferred embodiment, this type of textile based material contains polyester, especially PET and / or modified polyester. The latter may be used as the sole raw material or may be mixed with other polymer fibers (e.g., polyamide fibers, especially PA6).

The fiber linear density used is preferably in the range of 0.05 to 3 dtex. The fiber linear density used is most preferably in the range of microfibers, i.e., 0.1 to 1 dtex. The advantage of using microfibers is that they provide excellent cleaning results and are very soft to provide a pleasant feel. In particular, excellent cleaning results are achieved with microfibers having a linear density in the range of 0.05 to 1.0 dtex, preferably in the range of 0.1 to 0.7 dtex.

In one preferred embodiment of the present invention, the textile-based material comprises a continuous multicomponent filament, preferably a continuous two-component filament, having a linear density of 1.5 to 3 dtex in a bipplet state, To at least some extent, preferably to at least 60%, by continuous microfilaments.

In designating the ratio between the textile-based material and the coating / impregnation with PVF, the ratio between the textile-based material and the PVF microfoam is suitably selected because the PVF foam in principle loses its softness and thus results in a very hard cleaning cloth A cleaning cloth can be obtained in which the textile of the base material and the soft touch are kept at least partially even in the dry state.

In this context, it has been found that the ratio of the total weight of the cleaning cloth due to the PVF material should advantageously be less than 50 wt%, preferably less than 30 wt% for a substantially soft feel.

The total basis weight of the sheet material is preferably in the range of 90 to 350 g / m ² , more preferably 200 to 300 g / m ² . The amount of the hydrophobic fibers in such a sheet material is preferably in the range of 80 to 250 g / m ² , more preferably 150 to 200 g / m ² . The hydrophobic fibers used to produce the textile sheet material are available in a wide variety of styles at low cost, and color and coating / impregnation are simple to apply using conventional processes. The textile-based material may be coated / impregnated on both sides of it with both a PVA-containing dispersion or a PVA-containing polymer solution therein.

The cleaning cloth may thus be provided with different appearance and different cleaning properties (e.g., different degrees of water absorption) on both sides at low cost. Impregnation in accordance with the present invention is preferred. This is a simple way of introducing PVF foam into the interior of the textile sheet material in particular.

A uniform coating / impregnation can be provided in the sheet material, where the term "uniform coating / impregnation" should be understood to mean that the separation between PVF foamed areas and PVF foam free areas is on the average less than 5 mm . Thus, sheet material having a "uniform coating ", as defined above, can also have areas free of PVF foam. An advantage of this embodiment is that uniform coating / impregnation has the effect of solidifying the sheet material and thereby improving its stability. In addition, a high proportion of hydrophilic PVF results in particularly good removal of a relatively large amount of liquid from the surface to be cleaned. Secondly, the wiping will leave the liquid just thin and even on the surface to be cleaned. On a particularly polished surface, this ensures nonstripy cleaning compared to, for example, an uncoated microfibre cloth of knitting.

The coating / impregnation may possibly only be on one side of the wash cloth. This embodiment is advantageous in this case because the hydrophobic contaminants can simply be removed with the uncoated hydrophobic side of the sheet material and hydrophilic contaminants can be removed with the coated hydrophilic side of the sheet material. In a preferred embodiment of the present invention, however, the coating / impregnation is present on both sides of the wash cloth, since this leads to particularly advantageous use of the beneficial effects of the present invention.

In a particularly preferred embodiment of the invention, the at least one surface, preferably both surfaces, of the wash cloth has a smooth surface with a contact pressure in the range of 0.05 N / cm ² , especially 0.05 N / cm ² to 0.5 N / cm ² Upon cleaning, the hydrophobic fibers as well as any additional components of the textile-based material are allowed to contact the coated / impregnated PVF foam with the surface to be cleaned. The distribution of the PVF foam in contact with the area of the base material and of the surface to be cleaned is uniformly uniform (coated area spaced from 0.5 to 5 mm), an island-like, clearly spaced May have the form of a regular or irregular coating / impregnation pattern that produces a coated area.

The advantage of using a coating / impregnation pattern is that the PVF-containing coating / impregnation forms part of the surface and the hydrophobic microfibers form another part. Accordingly, there is a clear separation between the hydrophilic and hydrophobic regions, which makes the amphipathic nature of the wash cloth particularly prominent. This is why the partially coated surface of this type of cleaning cloth provides a particularly high cleaning effect with respect to both hydrophobic and hydrophilic contaminants, resulting in a great variety of uses.

In practical tests, 1-60%, preferably 5-20% of the total surface area in contact with the smooth surface to be cleaned under contact pressure of 0.05 N / cm ² , especially 0.05 N / cm ² to 0.5 N / cm ² , The cleaning cloth of the present invention in which 99-40%, preferably 95-80% of the contact surface is formed by PVF foam, while being formed by the fibers and / or yarns of the style-based material, Proved to be acceptable.

Textile sheet materials are not only solidified in principle, but also can use non-reinforced textile-based materials. However, in order to obtain a mechanically stable cleaning cloth, it is advantageous that the textile-based material is at least partially mechanically, thermally and / or chemically solidified. Especially in the case of batt, the fibers arranged randomly or partly side by side can be mechanically and / or thermally and / or chemically solidified by stitching.

The sheet material may be produced using fibers and / or yarns. The sheet material is preferably a nonwoven fabric, a knitted fabric, a laid fabric, a fabric, a braided fabric, an interlocked fabric, a felt, a cotton wool, a tufted fabric, Combinations and also other sheet-like structures.

The use of interloop fabrics or nonwoven fabrics is particularly preferred in the present invention. Interloop fabrics offer the advantage that the fibers can be introduced into the sheet material even in a large amount and with a relatively even distribution. In addition, the fibers in the interloop fabric are bonded in a mechanically stable state and therefore need not be further secured to one another. Nonwovens provide a simple and inexpensive advantage to produce.

In a preferred embodiment of the present invention, the textile-based material is an inter-loft fabric having a minimum ratio of loops. It should be understood that in the context of the present invention the term loop means that instead of a continuous loop of curves, a closed loop as well as an alternative cut loop, i.e. a projected fiber end, may also be present.

For the purposes of the present invention, it is preferred that the minimum proportion of loops is composed of microfibers, in particular continuous microfilaments.

The three-dimensional structure of the interloop fabric can be used in the cleaning cloth of the present invention by applying coating / impregnation in such an amount that each vertex of the loop is not completely covered by coating / impregnation. In this implementation, at least some of the loops can protrude out freely from the center plane of the cleaning cloth, especially in a thread loop. It is particularly preferred that the minimum proportion of loops be coated in the area of the center plane of the wash cloth, while the minimum proportion of the loops is uncoated at each of its vertexes. In a preferred embodiment of the present invention, the range of the loop at each vertex is narrower than the range in the area of the center of the wash cloth. Thus, the cleaning cloth preferably has a cross-section that has a higher percentage of PVF foam in the center than in the outer area. It is very particularly preferred that at least 80%, preferably at least 90% of the wash cloth has such a cross-section.

Based material may be obtained by using a corresponding small amount of coating / impregnating material. However, it is also possible that the partially free end of the base material at the surface of the coated / impregnated wash cloth is subsequently exposed in some other manner, such as rubbing the cloth surface initially.

The provision of a loop that is not completely covered by coating / impregnation at each corner has the advantage that the cleaning surface includes a hydrophobic loop fixed to the hydrophilic base. In practical testing, this type of cleaning surface has been found to have particularly useful amphipathic characteristics and to be of various uses. When microfibers are used, the fine microfibers protruding from the surface contribute to the cleaning performance of the superior cleaning cloth.

In the actual test, the loop range is the coated area of the loop and the non-coated area, both to all contact with the smooth surface to be cleaned 0.05 N / cm ^2, in particular the contact pressure of 0.05 N / cm ² to 0.5 N / cm ² Lt; RTI ID = 0.0 > washing performance. &Lt; / RTI >

The loop height may vary depending on the intended purpose. Good results are typically obtained at a higher loop height than the center plane in the range of 0.5 mm to 5 mm, preferably 1 mm to 2 mm. The loop density likewise depends on the intended purpose, for example in the range of 2 to 9 loops / cm, preferably in the range of 4 to 7 loops / cm, in the flow direction and / It can be different.

The basis weight of the wash cloth can be similarly varied depending on the intended purpose. The basis weight of from 90 to 350 g / m ² have been found to be advantageous for most purposes.

If the microfibers are used as fibers containing hydrophobic materials, they can be produced by splitting. In this case, the starting material is preferably spun at a linear density of at least 1 dtex, preferably of at least 1 dtex, as continuous multicomponent filaments, for example as continuous two-component filaments, . In this connection, it is preferred that at least 60%, more preferably 80% to 100% of the starting filament is splitted into the continuous micro filaments after splitting and prior to use.

In order to facilitate splitting of the continuous multicomponent filaments into the microfiber filaments, the continuous multicomponent filaments advantageously comprise at least two incompatible polymers, preferably polyester, in particular PET, and, on the other hand, , Polyamide, especially PA6 and the like.

Depending on the intended purpose, textile-based materials may be provided with easy-care and / or flame retardant properties. Thus, the fibers may consist of polymers containing up to 10 wt% of additives, such as coloring pigments, permanent antistatic agents, fungicides, bactericides, acaricides and / or components affecting hydrophilic or hydrophobic properties .

The textile-based material may comprise additional colored fibers, in which case the color of the continuous multicomponent filaments may be in the form of a solution color.

Due to its advantageous properties, the use of a textile sheet material as the cleaning textile is recommended. For example, a wiping or scouring transition can be made from this.

In a further development of the present invention, the textile sheet material surface coated / impregnated with PVF foam is applied thereto in a pattern printed by an abradant, for example a polishing particle. The polishing particles may be formed by, for example, diatomaceous earth. These particles impart a slight polishing effect to the wash cloth. Abrasives can be applied to textile-based materials in a simple printing process in a wide variety of ways. Thus, it is possible to achieve additional cleaning effects and also decorative effects on the textile structure.

For some intended purposes, it may be advantageous for the cleaning cloth to be raised, sanded, brushed, or calendered.

Likewise, it is possible to pretreat textile-based materials. Possibilities for this include printing, polishing, or partial embossing. When a colorless PVF foam is used, especially printing can be permanent and maintain the clarity of the wash-fastness even after coating / impregnation.

It is advantageous that the cleaning cloth can be produced in a variety of colors in order to indicate the use of the cloth only in one cleaning area, for example in the case of professional cleaning, for hygiene purposes. In the present invention, the coloring of the cloth can be performed, for example, as follows:

The textile-based material used is already partially or uniformly colored. When combined with a colorless PVF adduct, the background color of the underlying material is kept sharp and clear.

Alternatively, the PVA solution used to produce the PVF foam may also be mixed with a colored pigment. In this case, a colorless, therefore inexpensive base material may be selected and the coloring of the wash cloth may be omitted entirely or otherwise only selected or established at a later stage of the PVF coating / impregnation. This has particular logistical advantages. The dye can be selected again due to its ability to introduce into the PVF material in a durable wash-fastened state, especially without bleeding.

The present invention further provides a process for producing a cleaning cloth of the present invention comprising the steps of:

First, textile-based materials comprising microfibers comprising hydrophobic materials, especially hydrophobic materials, are typically produced and optionally solidified. When multicomponent fibers, particularly continuous multicomponent filaments, are used as the starting material, they can be split into microfibers by mechanical stress, for example, for processing into woven fabrics and / or interrupted fabrics . However, it is also possible to carry out a separate splitting step, for example by collision with a hydrojet.

Thereafter, the PVA, preferably in the form of an aqueous solution, may be applied, for example, by conventional application methods such as pad-mangling, blade coating, spraying, Based material through slop padding or through a slot die or a broad-slot die. It has been found particularly advantageous to impregnate textile based materials with PVA aqueous solutions. Excess PVA can be squeezed, bladed, inhaled or otherwise removed depending on the desired coating / impregnation thickness. Thus, the base material to be treated may be introduced into an aqueous salt solution and / or suspension, for example, a sodium sulfate solution, and subsequently an acidic formaldehyde solution. In aqueous salt solutions, the PVA solution loses water and the PVA solidifies. In an acidic formaldehyde solution, PVA is crosslinked to form PVF.

In an advantageous embodiment, the aqueous PVA solution and / or suspension contains another further added substance, for example a colored pigment or other additive or particles, such as the abrasives mentioned above. The PVA solution preferably has a PVA solids content of 1 to 10 wt.%, Preferably 3 to 7 wt.%.

As already mentioned hereinabove, the coating / impregnation does not completely cover the textile-based material for cleaning performance, but it does not cover the textile-based material in some areas of the base material, for example a loop protruding from the center face, It may be advantageous to leave a loop that has been created. To achieve this, the amount of PVF applied may be adjusted in the production process so that only a portion of the cleaning cloth surface is coated / impregnated. This may be accomplished by: a) saturating and / or applying the PVA solution over the entire width by a suitable amount of coating / impregnation of the PVA solution (e.g., by roll, sprayhead, etc.) , Or b) by partial application of the PVA solution in a dispensing fashion over an area ("island"), or c) subsequently polishing the PVF foam layer present on both outer surfaces of the wash cloth, Can be achieved by an associated laying bare of the material.

When a three-dimensional structure, for example a knitted fabric, is used as the starting material, the choice of application method determines whether the PVF is accumulated in the region of the center plane or on the projected structure. It has been found to be advantageous to squeeze excess PVF to produce a cleaning cloth having a lower coating / impregnation thickness at each corner than at the area of the center plane of the loop. In this way, the PVF accumulates around the center plane of the textile-based material.

The process of the present invention provides a simple but highly productive method for making a textile structure having a PVF-containing coating / impregnation on one or both sides. The PVF-containing coating / impregnation can be impregnated into the textile-based material to ensure secure attachment to the textile-based material.

In a particularly preferred embodiment of the present invention, the textile-based material is simultaneously coated on both sides in one machine. Thus, PVF-containing coatings / impregnations are applied to textile-based materials in one operation, contributing particularly high efficiency in the manufacture of textile structures.
