Description

Title: Wiper for cleaning and disinfecting objects and surfaces

description

The present invention relates to a wipe for cleaning and disinfecting objects and / or surfaces. The invention also relates to a dispenser and a cleaning device with the aforementioned laundry cloth. The invention also relates to a special use of the aforementioned laundry cloth and a method for producing a laundry cloth for cleaning and disinfecting objects and / or surfaces.

A certain storage capacity for a cleaning agent or disinfectant used is generally required for laundry towels. This is particularly the case with floor wipes. That is why many laundry towels contain cellulose-based fibers such as cotton fibers or viscose fibers, which can absorb water and temporarily bind it within their fibers, giving them good storage capacity.

Disinfectants that contain a quaternary ammonium compound (QAV) as an antimicrobial active component are used, among other things, for surface disinfection. Quaternary ammonium compounds are ionic, nitrogen-containing compounds and are positively charged. Conventional cellulose-based fibers, on the other hand, are normally negatively charged. If a washcloth with conventional cellulose-based fibers is used in combination with a QAV-containing disinfectant, the positively charged quaternary ammonium compound binds to the negatively charged fibers of the washcloth due to ionic forces of attraction. By binding the quaternary ammonium compound, the wipe removes the antimicrobially active ingredient from the disinfectant, which impairs the effectiveness of the disinfection process. For this reason, wipes with a high proportion of conventional cellulose-based fibers are now generally viewed as incompatible with QAV-containing disinfectants. Wipes made of synthetic fibers such as fibers made of polyethylene terephthalate (PET) or polypropylene (PP) do not retain quaternary ammonium compounds and are therefore well compatible with disinfectants containing QAV from a chemical point of view. However, the washing cloths then only have a low storage capacity, since the synthetic fibers are not absorbent and water storage can only be achieved through capillary bonding between the fibers. In order to ensure sufficient storage capacity, especially in the case of floor wipers, a lot of fiber material must therefore be used. This leads to thick towels that are unwieldy and expensive and are therefore only used as reusable items. In the field of clinical hygiene, however, the use of reusable items has turned out to be one of the main causes of the spread of germs and nosocomial infections in recent years.

The present invention was based on the object of providing a washcloth for the medical sector which is particularly well suited for surface disinfection using a QAV-containing disinfectant. In addition, the washcloth should have a good cleaning performance. These objects are achieved with a wiper according to claim 1 and a method according to claim 39.

The wipe according to the invention is intended for cleaning and disinfecting objects and / or inanimate surfaces in the medical field. It can be provided that the wiper is held in the hand, for example when it is used for cleaning and disinfecting objects and surfaces other than floor areas. Such a wipe that is held in the hand during washing and cleaning is also referred to here as a “surface wipe”. The cleaning cloth can, however, also be provided for cleaning and disinfecting floor surfaces, in which case it is usually used in conjunction with a corresponding cleaning device (“mop”). Such a cloth provided for cleaning and disinfecting floor surfaces is also referred to in the present case as a “floor cloth”. Any differences that may be provided between the surface and floor wipes (such as, for example, in size and shape or thickness) are described below in connection with the preferred embodiments of the invention. According to the invention, the wipe comprises a liquid-storing base material. The base material can be understood as the material of which the cloth essentially consists. Liquid-storing means that the base material can absorb liquid, the base material typically also being able to release liquid again during washing and cleaning. The base material is in the form of a fiber mixture. This means that the base material consists of different fibers that are mixed with one another and are not separate from one another. The base material or the fiber mixture comprises the following three components:

- 35 wt .-% to 75 wt .-% positively charged regenerated cellulose fibers

15 wt% to 55 wt% synthetic fusion bonding fibers

- 5% by weight to 35% by weight synthetic microfibers

The above three fiber materials provided according to the invention are typically staple fibers.

The regenerated cellulose fibers according to the invention are chemically modified by an additive compared to conventional regenerated cellulose fibers such as, for example, viscose fibers, that they are positively charged overall. The expression "positively charged" is to be understood as meaning that the fiber material is positively charged in total. The regenerated cellulose fibers according to the invention can therefore also contain negative charges due to corresponding chemical functional groups; however, these are compensated for by the positive charges that are clearly in abundance and do not lead to any significant QAV binding. The exact nature of the regenerated cellulose fibers according to the invention is described in more detail below.

The fusion binding and microfibers according to the invention do not contain any naturally occurring polymers such as cellulose in particular and are also not based on naturally occurring polymers, which is intended to be expressed by the term “synthetic”.

Since the regenerated cellulose fibers are positively charged, quaternary ammonium compounds are not bound to the fibers, or only in small amounts.

As a result, the washcloth can be compatible with QAV-containing disinfectants, with the regenerated cellulose fibers at the same time not losing their advantage of storage capacity or absorbency due to the chemical modification. By using the positively charged regenerated cellulose fibers, the inventive The wipe must therefore be compatible with disinfectants containing QAV and be able to store liquids to a high degree. These two advantages, which are decisive for surface disinfection, are not present in many conventional laundry towels from the prior art, as shown above.

Another advantage of the wipe according to the invention results from the synthetic microfibers. Thanks to the microfibres, the laundry towel can absorb dirt better and its cleaning performance can be improved.

Finally, according to the invention, synthetic fusion binding fibers are also provided in the fiber mixture. They can be brought into a softened and flowable state by the influence of heat, which enables other fibers to be partially embedded. Thus, the fusible bonding fibers can give the laundry cloth a strength required for washing and cleaning. The fusion binding fibers are therefore used to make the washcloth stable and resistant, so that it remains intact when wiping and cleaning.

Another advantage of the wipe according to the invention is that it can be produced comparatively inexpensively and contains a high proportion of biodegradable material in the form of the positively charged regenerated cellulose fibers. Further advantages of the invention emerge from the preferred embodiments described below.

In a particularly preferred embodiment of the invention, the wipe is provided as a disposable item. If the washcloth is used for cleaning and disinfection in the medical field and, according to this preferred embodiment, is disposed of after a single use, the spread of germs and nosocomial infections can thus be better prevented.

The wipe according to the invention can be provided to the user in a dry state by the manufacturer. However, it can also be advantageous for handling if the laundry cloth is provided by the manufacturer pre-moistened with a disinfectant. This washcloth was specially developed for use with QAV-containing disinfectants. Accordingly, the disinfectant used for pre-moistening preferably comprises a quaternary ammonium compound as an antimicrobial active ingredient. A QAV-containing disinfectant suitable for pre-moistening is Mikrobac forte from Bode Chemie (Hamburg, Germany). The pre-moistening of the surface wipe with the disinfectant could be, for example, 300% by weight to 400% by weight, based on a dry weight of the surface wipe. For example, if the surface wipe weighs 7 grams dry and 28 grams pre-moistened, this would correspond to a pre-moistening of 300% by weight. In the case of the floor wipe, a higher range can be advantageous for the pre-moistening, for example 750% by weight to 900% by weight, based on a dry weight of the floor wipe. The mentioned areas for pre-moistening represent an actual degree of impregnation of the wipes with the disinfectant. This must be distinguished from the maximum degree of impregnation described below, which is a material-specific parameter and basically indicates the maximum amount of liquid that can be used to impregnate the material in question.

In order to further improve the cleaning performance, the wiping cloth can have an abrasive coating. The abrasive coating is usually applied to the base material, for example using a gravure printing process. The abrasive coating can be applied on only one side or on both sides of the base material. Furthermore, the abrasive coating is preferably designed in the form of strips, the strips advantageously also being able to have a grid-like pattern. The height of the abrasive coating can be 0.1 mm to 0.8 mm, preferably 0.2 mm to 0.4 mm, which can be measured with a microscope. The height here means the extension of the coating perpendicular to the direction of the areal extension of the wipe. Furthermore, the abrasive coating can be a synthetic polymer (plastic) such as polyethylene (PE), polypropylene (PP), an amorphous polyalphaolefin (APAO), ethylene vinyl acetate (EVA), an ethylene vinyl acetate copolymer (EVAC), a polyamide (PA), an olefin-based thermoplastic elastomer (TPE-O), a crosslinked olefin-based thermoplastic elastomer (TPE-V), a thermoplastic copolyester (TPE-E), a urethane-based thermoplastic elastomer (TPE-U), a thermoplastic copolyamide (TPE-A ), a thermoplastic styrene block copolymer (TPE-S), a styrene-ethylene-butadiene-styrene polymer (SEBS), styrene-butadiene-styrene (SBS) or styrene-ethylene-propylene-styrene (SEPS) or of a such polymer exist. In particular, the abrasive coating comprises or consists of ethylene vinyl acetate (EVA). The material of the abrasive coating also preferably has a Shore A hardness of 50 to 100, in particular 70 to 100, determined in accordance with DIN 53505: 2000-08 and ISO 868: 2003 (E). As already mentioned, the wipe consists essentially of the base material. If the aforementioned abrasive coating is present, the wipe then usually consists of the base material, the abrasive coating, optionally a liquid disinfectant (if it is the pre-moistened wipe) and optionally a suture material (if the wipe is sewn as described below) . However, it is also possible that the wipe consists only of the base material, optionally the liquid disinfectant and optionally the suture material, in which case the aforementioned abrasive coating would not be provided.

In addition to the positively charged regenerated cellulose fibers, the synthetic fusion binding fibers and the synthetic microfibers, the base material of the wipe could also contain one or more other fiber materials in an amount of preferably not more than 15% by weight. In this context, for the desired compatibility of the wipe with QAV-containing disinfectants, it should be noted that the base material typically does not contain any fibers made from a naturally occurring polymer and, with the exception of the positively charged regenerated cellulose fibers, also no fibers based on a naturally occurring polymer. Particularly preferably, the base material consists of the positively charged regenerated cellulose fibers, the synthetic fusion binding fibers and the synthetic microfibers.

Preferred embodiments of the invention can also be specified with regard to the weight ranges of the three fiber materials provided according to the invention.

The base material preferably comprises or consists of:

- 40 wt .-% to 65 wt .-% of the positively charged regenerated cellulose fibers

15% to 50% by weight of the synthetic fusion bonding fibers

- 5% to 25% by weight of the synthetic microfibers

More preferably, the base material comprises or consists of:

45% by weight to 60% by weight of the positively charged regenerated cellulose fibers

15% to 35% by weight of the synthetic fusion bonding fibers

10% to 25% by weight of the synthetic microfibers

Even more preferably, the base material comprises or consists of:

- approx. 50% by weight of the positively charged regenerated cellulose fibers

- about 35% by weight of the synthetic fusion bonding fibers - about 15% by weight of the synthetic microfibers

In particular, the base material comprises or consists of:

- approx. 55% by weight of the positively charged regenerated cellulose fibers

- about 30% by weight of the synthetic fusion bonding fibers

- about 15% by weight of the synthetic microfibers

The base material is preferably designed as a nonwoven fabric. Nonwovens can be produced comparatively easily and cheaply. The base material, in particular as a nonwoven, is usually consolidated by needling using high pressure water jets (spunlace process). This can reduce the surface lint tendency. In addition, the base material is normally solidified by partial melting of the fusion bonding fibers. This allows the tensile strength of the base material to be adjusted.

The base material can advantageously also be provided with an embossed pattern. According to this particularly preferred embodiment of the invention, the base material thus has an embossed pattern. As a result, the sliding ability of the wipe can be improved, which can be of particular importance for the floor wipe in particular. The embossed pattern is preferably designed in a diamond shape, rod shape or honeycomb shape. In particular, the rod-shaped configuration of the embossed pattern is preferred in the present case. The base material is usually provided with the embossed pattern over the entire surface. The embossing pattern can be formed, for example, by depressions on the side of the base material provided for wiping, the depressions being made in the base material, for example, with a corresponding embossing roller. In particular, the embossing pattern is produced in the base material by means of a hot calender. This enables a particularly permanent embossing to be achieved.

For the wiper, in particular for its base material, advantageous values for size and shape, thickness, weight per unit area, volume weight, sinking time, water retention capacity, maximum degree of impregnation, area performance, tear resistance, QAV compatibility and the coefficient of friction can also be used can be specified. The values relate in particular to the base material without an abrasive coating possibly comprised by the wiper. The wiping cloth, in particular the base material, can be designed essentially rectangular and have a length of 10 cm to 60 cm and a width of 10 cm to 60 cm. As a surface wipe, it can advantageously have a length of 18 cm to 40 cm, in particular approximately 30 cm, and a width of 18 cm to 40 cm, in particular approximately 30 cm. As a floor wipe, it can advantageously have a length of 40 cm to 60 cm, in particular approximately 43 cm, and a width of 10 cm to 20 cm, in particular approximately 13 cm. The preferred strip-like shape of the floor cloth fits the cloth holders of conventional wiping systems.

The washcloth, in particular the base material, can have a thickness of 0.5 mm to 5 mm. As a surface wipe, it can advantageously have a thickness of 0.5 mm to 1.5 mm, preferably 0.8 mm to 1.1 mm. A particularly high suction force is desired for the floor wipe, which is why it advantageously has a thickness of 2 mm to 4 mm, preferably 2.5 mm to 3.2 mm. The preferably higher values for the thickness also result, among other things, in a higher weight per unit area and an advantageously higher tear resistance of the floor wipe compared to the surface wipe. The specified values for the thickness refer to the dry, single-ply (i.e. not folded or stacked) washcloth or base material. The thickness of the washcloth can be determined using a specific measuring pressure of 0.5 kPa on a feeler area of 25 cm ² . In particular, a DMT thickness measuring device from Schröder can be used. In addition, the thickness can be determined based on DIN EN ISO 9073-2: 1995.

The washcloth, in particular the base material, can have a weight per unit area of 40 g / m ² to 400 g / m ² . As a surface wipe it can advantageously have a weight per unit area of 50 g / m ² to 100 g / m ² , preferably from 70 g / m ² to 90 g / m ^2. As a floor wipe it can advantageously have a weight per unit area of 200 g / m ² to 400 g / m ² , preferably from 220 g / m ² to 300 g / m ² . The values given for the basis weight refer to the dry, single-ply (i.e. not folded or stacked) washcloth or base material. The weight per unit area can be determined based on DIN EN 29073-1: 1992, with the test specimens having an area of 100 cm ² instead of 500 cm ² .

The wiping cloth, in particular the base material, can have a density of 0.077 g / cm ³ to 0.104 g / cm ³ . The specified values for the volume weight refer to the dry linen or base material. The Volume weight can be determined from the weight per unit area and the thickness of the wipe using the following formula:

Volume weight [g / cm ³ ] = weight per unit area [g / m ² ] / (thickness [mm] x 1000)

The washcloth, in particular the base material, can have a sinking time of a maximum of 10 seconds, preferably a maximum of 8 seconds and even more preferably a maximum of 5 seconds. The sinking time is a measure of how quickly the laundry can absorb liquid. A short sinking time can accelerate the cleaning or disinfection process. The sinking time is determined according to the test method described below.

The washcloth, in particular the base material, can have a water retention capacity of at least 6 g / g, preferably of at least 8 g / g and even more preferably of at least 10 g / g. The water holding capacity is a measure of how much liquid can be absorbed by the laundry towel. The greater the water holding capacity, the more area can generally be cleaned and disinfected in one pass with the laundry cloth. The water holding capacity is determined according to the test method described below.

The washcloth, in particular the base material, can have a maximum degree of impregnation (maximum impregnation) of at least 600% by weight, preferably of at least 700% by weight and even more preferably of at least 800% by weight. The maximum degree of soaking, like the water holding capacity, is a measure of how much liquid can be absorbed by the laundry towel. The greater the maximum degree of impregnation, the more area can generally be cleaned and disinfected in one pass with the laundry cloth. The maximum degree of impregnation is determined according to the test method described below.

The washcloth, in particular the base material, can have an area performance of at least 16 m ² , preferably of at least 18 m ² and even more preferably of at least 20 m ² . These values refer to the floor wipe. The area performance is a measure of how much area can be cleaned and disinfected in one go with the liquid-soaked cloth. The area performance depends, among other things, on the water holding capacity, the degree of impregnation and the area weight. The area performance is determined according to the test method described below. The wiping cloth, especially the base material, as a surface wiping cloth, can have a tear strength in the longitudinal direction (machine direction, MD) of 25 N / 25 mm to 40 N / 25 mm and in the transverse direction (transverse to the machine direction, CD) of likewise 25 N / 25 mm to 40 N / 25 mm. For the floor wipe, the values are advantageously 50 N / 25 mm to 80 N / 25 mm (MD) and 70 N / 25 mm to 90 N / 25 mm (CD). The tear resistance is a measure of the stability of the laundry towel. A high tear resistance ensures that the linen remains intact when washing and cleaning. The tear strength is determined according to the test method described below.

The wipe, in particular the base material, can have a compatibility with a disinfectant comprising a quaternary ammonium compound as an antimicrobial active ingredient of at least 80%, preferably of at least 85% and particularly preferably of at least 90%. Thus, after 24 hours of contact between the washcloth, in particular the base material, the disinfectant still contains at least 80%, preferably still at least 85% and particularly preferably still at least 90% of an initial concentration of the antimicrobial active ingredient in the disinfectant. The compatibility can relate to the quaternary ammonium compound benzylalkyldimethylammonium chloride (BAC) and can be determined using the test method described below.

The wiping cloth, in particular the base material, can have a coefficient of friction of a maximum of 0.7 in the longitudinal direction and of a maximum of 0.6 in the transverse direction. A lower limit for the coefficient of friction in both the longitudinal and transverse directions can be 0.4. The aforementioned values can relate to the static and / or dynamic, in particular only the static, coefficient of friction. In addition, the aforementioned values relate in particular to the floor wipe. In the present case, the coefficient of friction is a measure of the sliding ability of the laundry towel. The lower its value, the easier it is to move the wipe over a surface. With a lower coefficient of friction, the cleaning process with the cloth requires less effort on the part of the user. The coefficient of friction is determined using the test method described below.

The regenerated cellulose fibers can contain a cationic starch for the positive charge. In particular, the starch is spun into a matrix of regenerated cellulose fibers so that it cannot become detached from the fibers. In other words, the positively charged regenerated cellulose fibers can be fibers comprising or consisting of a regenerated cellulose and a cationic starch, in particular a mixture of a regenerated cellulose and a cationic starch. The regenerated cellulose is preferably viscose. The cationic starch is preferably (3-chloro-2-hydroxypropyl) trimethylammonium chloride modified starch (systematic name: starch, 2-hydroxy-3- (trimethylammonio) propyl ether, chlorides; CAS No. 56780-58 -6). Such positively charged regenerated cellulose fibers are known and commercially available under the name DANUFIL ^® QR (Kelheim, Kelheim, Germany), from US 5,542,955 A (see Example 2).

The fusible bonding fibers are preferably bicomponent fibers. These typically consist of a low-melting polymeric component and a higher-melting polymeric component, which preferably have a sheath-core arrangement. The sheath is formed by the low-melting component. The core is formed by the higher-melting component. The terms “lower” and “higher” are to be understood with reference to the respective other polymeric component.

The fusion bonding fibers can consist of polyesters, polyolefins (such as, for example, polypropylene or polyethylene), polyamides, or mixtures thereof. The melt-bonding fibers preferably consist of polyesters, in particular polyethylene terephthalate (PET) and polyethylene terephthalate-co-isophthalate. The latter copolymer has a melting point of 110 ° C, which is significantly lower than that of PET (approx. 255 ° C). The jacket described above could therefore be formed from the copolymer. The core described above could then be formed by the PET. It is also conceivable that the fusion bonding fibers consist of polylactides (PLA).

The microfibers can have a fiber fineness of 1 dtex or less, in particular 0.9 dtex or less. As a rule, the finer the fibers, the better the cleaning performance of the wiper. The microfibers can consist of a polyester, a polyolefin (such as polypropylene or polyethylene) or a polyamide. The microfibers preferably consist of a polyester, in particular polyethylene terephthalate. In the case of microfibers, it is also conceivable that they consist of a polylactide. The present invention also relates to a dispenser comprising one or more wipes according to the invention in all of the embodiments described in the present application and combinations thereof. The dispenser can comprise a bag, in particular a flow pack packaging, in a manner similar to that shown, for example, in WO 2008/122961 A1. However, similar to that shown in EP 2 727507 A2, the dispenser can also comprise a container, in particular a bucket. The wipes are contained in the bag or the container. The dispenser can protect the laundry towels from contamination and provide an easy-to-handle storage option for the laundry towels that can ideally be closed again after they have been opened for the first time. If the dispenser contains a disinfectant, in particular a disinfectant containing QAV (for example by filling the bag or container of the dispenser with a disinfectant), the previously mentioned pre-moistened wipes can be obtained. Such a dispenser can then also be referred to as a wet wipe dispenser.

Furthermore, a cleaning device, in particular a mop, with a washcloth according to the invention in all of the embodiments described in the present application and their combinations is claimed. The cleaning device comprises, in particular, a handle and a receptacle or holder for the laundry cloth. In order to be able to easily attach the laundry towel to the holder, it advantageously has two pockets. These can be formed by turning over the washcloth or its base material at two opposite ends and sewing or ultrasonically welding the two-layer area at the edge. Correspondingly, in a further embodiment of the invention, the floor wipe can have two pockets for attachment to a cleaning device, in particular a washing mop.

Another object of the present invention is a non-therapeutic use of a washcloth according to the invention in accordance with the embodiments described in the present application and their combinations for cleaning and / or disinfecting objects and / or inanimate surfaces. It is used in particular in the medical field, especially in a hospital. The objects can accordingly be medical devices and furnishings usually found in patient rooms, treatment rooms and operating theaters of hospitals, which have to be regularly wiped down and disinfected (such as a Hospital bed). The surfaces can be part of the aforementioned devices and furnishings or floor surfaces.

Finally, the invention relates to a method for producing a wipe for cleaning and disinfecting objects and / or surfaces. The method comprises the following steps: i. Providing a fiber mixture comprising or consisting of

- 35 wt .-% to 75 wt .-% positively charged regenerated cellulose fibers,

- 15% by weight to 55% by weight synthetic fusion binding fibers,

- 5% by weight to 35% by weight synthetic microfibers. ii. Solidification of the fiber mixture by needling by means of high pressure water jets (spunlace process) and by partial melting of the fusion binding fibers, a liquid-storing base material, in particular non-woven base material, of the washcloth being formed. iii. Optional embossing of the base material so that the base material is provided with an embossed pattern. The embossing is advantageously carried out by means of a hot calender. iv. Optional application of an abrasive coating to the base material. v. Optional formation of two pockets for attachment to a cleaning device, in particular a washing mop, the pockets being formed by sewing the base material or by ultrasonic welding of the base material.

To carry out the individual steps, conventional techniques known per se to those skilled in the field of textile production, in particular nonwovens production, such as the use of embossing rollers (with reference to step iii.), The screen printing process or the gravure printing process (with reference to step iv.) are used. A synthetic thread (plastic thread) can be used as a suture material to sew the base material.

The proposed method can also be used to produce the preferred embodiments of the laundry cloth (and combinations thereof) described in the present application. The washcloths produced by this method thus optionally have the features of the preferred embodiments of the wipe according to the invention described above. Examples and figures

The invention is to be explained and illustrated in more detail by way of example with the examples and figures described below.

Manufacture of wipes

Four different wipes were produced for cleaning and disinfecting floor surfaces in the medical field. For this purpose, the fiber blends indicated in Table 1 were first produced.

Table 1: fiber blends

[% By weight] [% by weight] [% by weight] [% by weight]

Cotton fibers 50 positively charged - 50 55 60

Viscose fibers

Bicomponent 44 44 30 20 fibers

polyester

Microfibers made from 6 6 15 20

polyester

Accordingly, the fiber mixture 1 consisted of 50% by weight cotton fibers, 44% by weight bicomponent fibers and 6% by weight microfibers. Fiber mixture 2 consisted of 50% by weight of positively charged viscose fibers, 44% by weight of bicomponent fibers and 6% by weight of microfibers.

Fiber mixture 3 consisted of 55% by weight of positively charged viscose fibers, 30% by weight of bicomponent fibers and 15% by weight of microfibers.

Fiber mixture 4 consisted of 60% by weight of positively charged viscose fibers, 20% by weight of bicomponent fibers and 20% by weight of microfibers.

The positively charged viscose fibers were the aforementioned Danufil ^® QR fibers from Kelheim Fibers (Kelheim, Germany).

The bicomponent fibers had a sheath-core arrangement, the sheath consisting of polyethylene terephthalate-co-isophthalate and the core consisting of polyethylene terephthalate. The microfibers had a fiber fineness of 0.9 dtex and consisted of polyethylene terephthalate.

The fiber blends were processed into layers of wadding fleece. These were solidified by high-pressure water-jet needling (spunlace process) and partial melting of the bicomponent fibers. With the exception of wipe 2, the solidified nonwoven layers were provided with an abrasive coating of ethylene vinyl acetate as shown in FIG. In addition, a variant of wipe 3 was also produced for the lubricity test, which was provided with a rod-shaped embossing pattern as shown in FIG. The solidified and optionally coated and embossed nonwoven layers formed the wipes, which, as already mentioned, were intended as floor wipes.

Wipe 1 is not a wipe according to the invention, since it does not contain any positively charged regenerated cellulose fibers. Wipe 1 serves only as a control or comparison sample. The wipes 2 to 4, on the other hand, are wipes according to the invention.

The previously mentioned fleece layers of the wipes 2 to 4 represent the basic material according to the claims.

The sinking time, the water retention capacity, the maximum degree of impregnation, the area performance, the tear resistance and the compatibility with a QAV-containing disinfectant were tested for each of the wipes 1 to 4. The wipes 2 to 4 were also examined with regard to the lubricity. The tests are explained in more detail below before the test results are discussed.

Test for sinking time and water holding capacity The test method for determining the sinking time and water holding capacity is as follows: i. Sample material is punched from the wipe with a punch knife (10 x 10 cm). ii. An empty, cylindrical wire basket made of copper wire (diameter of the wire: 0.4 mm; height of the basket: 8 cm; diameter of the basket: 5 cm; mesh size of the basket: 1.5-2 cm) is weighed (mi). iii. At least 5 g of sample material are placed in the basket. The basket filled with sample material is weighed again (GT ^). iv. A beaker (diameter: 11-12 cm) is filled with demineralized water up to a height of about 10 cm filled. v. The basket is dropped horizontally onto the water from a height of 10 cm. vi. A stopwatch is used to measure the time it takes for the basket to sink below the surface of the water. This is the sinking time. vii. Immediately after the basket has dropped below the surface of the water, the basket is lifted out of the water and held horizontally in its longitudinal axis for 30 seconds to allow it to drip off. viii. After draining, the basket is placed in a beaker with the mass rrb and weighed one last time (mu).

The water holding capacity in g / g is then calculated using the following formula: g m4 - (m2 + m3)

Water holding capacity in - = - g m2 - ml

For example, in the above test, take 5 g dry sample material (rri2 - rrn) 30 g water

(rru - (rri2 + b)), the result is a water holding capacity of 6 g / g.

The sinking time and the water holding capacity are taken as the mean of three

Provisions specified.

Test for the maximum degree of impregnation

The test method for determining the maximum degree of impregnation (maximum impregnation) is as follows: i. The dry wipe is weighed (rrn). ii. The wipe is placed in a container filled with demineralized water. The wipe remains there for about 10 minutes so that it is saturated with water. iii. Then the wipe is removed from the water tank and allowed to drain for 30 seconds. iv. Finally, the damp wipe is weighed (mb).

The maximum degree of impregnation in% by weight is then calculated using the following formula:

/ m2 - ml \ maximum degree of soaking in% = (- - -) x 100 For example, if in the above test a dry wipe with a weight of 5 g (rrn) takes up 30 g of water (rri2 - rrn), the result is a maximum degree of impregnation of 600% by weight.

The maximum degree of impregnation is given as the mean value from three determinations.

Area performance test The test method for determining the area performance is defined by the following protocol: i. The wipe with the dimensions 13 cm x 43 cm is soaked with demineralized water until saturation (as in the test method for determining the maximum degree of soaking) and then allowed to drip off for 30 seconds. ii. The wiping cloth is stretched onto a mop holder. iii. Then the following floor surfaces are wiped one after the other with the mop: a. Plastic floor, approx. 10.3 m ² ("laboratory") b. polished natural stone tiles, approx. 6.7 m ² (“hallway”) c. semi-gloss stoneware tiles, approx. 6.9 m ² ("toilet")

As soon as the closed liquid film breaks off, the test is considered to have ended. The floor area wiped up to that point is the area performance. In the present case, an area performance of 24 m ² means that the test floor areas a, b and c could be wiped completely with the laundry cloth without the liquid film tearing off. If there is sufficient residual moisture in the washcloth after wiping the floor areas a to c, the test floor area b (“corridor”) is wiped until the closed liquid film is torn off and the area wiped is then determined.

With this test method, particular care is taken to ensure that it is always carried out by the same person and in the same manner. The area performance is given as the mean value from at least three determinations.

Tear Strength Test The test method for determining tear strength (maximum tensile force) is as follows: i. A sample with a width of 25 mm and a length of at least 30 mm, preferably 50 mm, is punched out of the washcloth. In doing so, the sample die cut in either the machine direction (MD) or the transverse direction (cross machine direction, CD). ii. The sample strip is fixed vertically and tension-free in the clamps of a tensile testing machine (according to DIN 51221) with a clamping width of 25 mm and a clamping length (the distance between the clamps) of 30 mm. iii. The sample strip is then moved apart in the plane of its extension at a speed of 100 mm / min. The tensile force acting in this direction is measured. The tear strength is understood to mean the maximum force at which the sample strip tears. The specification is made in N / 25mm. If higher force peaks are measured beforehand in the course of elongation, then these represent the tear strength in the sense of this test.

The tear strength is given as the mean value of five determinations, samples from different areas or over the entire width of the wipe being used.

Test for compatibility with a QAV-containing disinfectant The test method for determining the compatibility with a QAV-containing disinfectant is as follows: i. The wipe is soaked based on DIN 53923: 1978-01. The wipe is placed in a disinfection tub, which is then filled with a disinfectant (Mikrobac forte; Bode Chemie, Hamburg, Germany). The wiping cloth is weighted down with a wire mesh made of stainless steel so that it is always covered by the liquid and does not float on the surface of the liquid. The disinfectant contains benzylalkyldimethylammonium chloride (BAC) as a quaternary ammonium compound in a concentration of 0.1%. ii. After an exposure time of 60 seconds, both the wire mesh and the wipe are removed from the disinfection tub. The wipe is allowed to drain for 120 seconds. iii. Immediately afterwards, the damp wipe is placed in a second, empty disinfection tub and the tub is closed with a lid. The wipe remains there for a period of 24 hours. iv. After the 24-hour exposure time has elapsed, the wipe is removed from the tub. The wipe is wrung out. The one from the wipe released liquid (hereinafter referred to as "test solution") is collected and used for the subsequent analysis v. An HPLC analysis is carried out under the following conditions:

- HPLC device: Agilent Technologies 1200 Series

- stationary phase: silica gel RP-8 (column from Macherey-Nagel, designation "150 / 4.6 Nucleodur 100-5 C8 ec"; heated to 40 ° C)

- mobile phase: 65% double-distilled water and 35% acetonitrile (water and acetonitrile each mixed with 0.1% phosphoric acid)

- Pressure: 130 bar

- Volume flow: 1.5 ml / min

- Sample injection: 0.02 ml / sample

- measured sample material:

- Sample 1: Sample with BAC in a known amount as an external standard

- Sample 2: Sample of the disinfectant used without contact with the wipe

- Sample 3: test solution

With the results of the HPLC analysis, the BAC concentration of the disinfectant without contact with the wipe (BAC concentration of sample 2) and the BAC concentration of the disinfectant after 24 hours of contact with the wipe (BAC concentration of sample 3 and the test solution) can be determined exactly. The QAV compatibility is then determined using the following formula:

/ BAC concentration sample 3 \

QAV compatibility in% = (- - -) x 100

\ BAC concentration sample 2 /

The values for the QAV compatibility thus indicate what percentage of the quaternary ammonium compound BAC is still contained in the disinfectant after 24 hours of contact with the wipe. The values therefore relate to the free QAV quantity of the disinfectant that is still available for disinfection in relation to its initial concentration.

The QAV compatibility is given as the mean value from two determinations. Lubricity test

The sliding ability is determined based on DIN EN ISO 8295: 2004-10. The sequence of the test method can be briefly summarized as follows: i. A plate made of PVC is attached to a sample table. The PVC plate corresponds to a conventional PVC floor, as is often found, for example, in patient rooms in hospitals. ii. A sample (120 mm x 80 mm) is taken from the wipe. iii. The sample is placed in Mikrobac forte 0.5% (Bode Chemie, Hamburg, Germany) for one minute and then allowed to drip off for two minutes. Mikrobac forte is a surface disinfectant and, as already mentioned, contains benzylalkyldimethylammonium chloride (BAC) as a quaternary ammonium compound. The aforementioned concentration of 0.5% relates to the amount of the concentrate supplied by the manufacturer in the ready-to-use solution (that is, 5 ml of concentrate are diluted with 995 ml of water). The BAC concentration of the ready-to-use solution is then 0.1% (as in the QAV compatibility test). iv. The sample is placed on the PVC plate and loaded with a friction block of certain dimensions and a certain weight. The side of the wiping cloth intended for washing (i.e. the side intended for floor contact) is brought into contact with the PVC plate. v. The sample is connected to the clamp of a tensile testing machine by means of a cord and subjected to a uniform relative movement (clamping length 30 mm; speed 100 mm / min). vi. The frictional resistance that arises from the frictional stress between the PVC plate and the sample is recorded with the aid of a force transducer and then converted into the static coefficient of friction ps or dynamic coefficient of friction P _D. The coefficients of friction are known to be dimensionless quantities. With a coefficient of friction of 0 there would usually be no adhesion. With a coefficient of friction of 1, on the other hand, complete adhesion would usually take place, so that no movement of the sample along the PVC plate would be possible.

The test method is carried out at 23 ± 2 ° C and 50 ± 5% relative humidity.

The sliding ability is determined in a similar way to the tear strength in the longitudinal direction and in the grain direction. “Longitudinal direction” means that the test direction is parallel to the longitudinal direction of the wipe. Accordingly, “transverse direction” means that the test direction is perpendicular to the longitudinal direction of the wipe. In addition, the sliding ability is determined from the resting position (static coefficient of friction ps) and (only) in motion (dynamic coefficient of friction P _D ). The values given for the coefficient of friction are mean values of triplicate measurements of the respective sample.

The sequence of the test method accordingly deviates from the specified standard (DIN EN ISO 8295: 2004-10) in the following points:

- A PVC plate ("PVC floor") is used as the surface - the dimensions of the sample are only 120 mm x 80 mm

- The sample is treated with a disinfectant and therefore tested in a moist state

- Number of samples: n = 2 per washcloth (1 x lengthways, 1 x transversely)

Test results

Table 2 summarizes the results of the tests with regard to the sinking time, the water holding capacity, the maximum degree of impregnation, the area performance, the tear resistance and the QAV compatibility. In addition, the thicknesses and the basis weights are listed in Table 2. The values for the area performance refer to the towels with the abrasive coating (if available). Otherwise, the values refer to the fleece layers (the base material) of the towels without an abrasive coating. None of the towels from Table 2 had an embossed pattern (that is, all values from Table 2 relate to wipes or nonwoven layers without an embossed pattern).

As can be seen from Table 2, the washcloths 2 to 4 according to the invention have a significantly shorter sinking time than the control wipe 1. That is, the inventive washing cloths can absorb liquid much more quickly than the cotton-containing control wipe 1. The cleaning or disinfection process can be accelerated.

The water holding capacity of the towels 1 to 3 is roughly the same, so that they can absorb roughly the same amount of liquid. Laundry cloth 4 has a higher water retention capacity than the other three laundry towels, which can be attributed to the high proportion of absorbent fiber material.

The area performance of the wipes 2 to 4 according to the invention is greater than that of the control wipe 1. In particular, the towels 2 and 3 show a particularly high area performance. With the towels according to the invention, a larger area can thus be cleaned and disinfected in one go. QAC compatibility is significantly better with wipes 2 to 4 according to the invention than with control wipe 1. Thus, after incubation for 24 hours, about 90% of the quaternary ammonium compound is still in solution with wipes 2 to 4, whereas with control wipe 1 only 69% of the quaternary ammonium compound is still present in the solution. This means that the inventive washing cloths only bind about 10% of the quaternary ammonium compound within 24 hours, but the control wipe more than 30% in the same period of time. This difference is seen as the essential advantage of the inventive washcloths compared to the cotton-containing control wipe, because this enables reliable disinfection with a QAV-containing disinfectant in the first place. The advantageous behavior towards QAV-containing disinfectants works in a synergistic way with the other advantageous properties of the laundry cloth, as described above (rapid liquid absorption and storage capacity, good area performance).

Abrasive coating

FIG. 1 shows one side of a laundry towel according to the invention in a preferred embodiment. The washcloth is intended as a floor wipe. There is a ruler on the wiping cloth to make the proportions clear. In particular, the abrasive coating of the wiping cloth can be seen in FIG. This consists of a material usually used as a hotmelt adhesive, namely ethylene vinyl acetate (EVA). The abrasive coating is designed in the form of strips, the strips being patterned in the form of a grid. The abrasive coating can further improve the cleaning performance of the laundry cloth, which can be particularly advantageous if stubborn dirt is to be removed.

Embossing pattern

FIGS. 2 to 4 show further preferred embodiments of floor wipes according to the invention in the upper half of the picture. In addition to the abrasive coating already described in connection with FIG. 1, these are also provided with an embossed pattern. The course of the embossing pattern is also shown in the lower halves of FIGS. 2 to 4 in the form of technical drawings (not true to scale). The patterns are formed by depressions on the side of the wipes intended to come into contact with the floor and are embossed into the wipes by means of appropriate rollers. The embossing pattern from FIG. 2 is referred to here as diamond-shaped. The embossing pattern from FIG. 3 is referred to here as rod-shaped, albeit like The figure shows that punctiform embossments are also included. The last embossing pattern shown by way of example from FIG. 4 is referred to here as honeycomb-shaped. As can be seen from the figures, the embossed patterns are designed to be comparatively fine or close-meshed. The side length of the rhombuses shown in FIG. 2 is actually only about 2.4 mm. The length of the “rods” from Figure 3 is actually only about 3.2 mm or 4 mm. The side lengths of the honeycombs from FIG. 4 are actually only about 6 mm. With a full-surface embossing pattern as shown in FIGS. 2 to 4, the sliding properties of the floor wipes can be improved. This is confirmed by the experimental data described below.

FIGS. 5a to 5d graphically represent the test results with regard to the lubricity in the form of bar graphs. Laundry cloth 2 was provided neither with an abrasive coating nor with an embossed pattern. Laundry 3 was examined in two variants. Once with an abrasive coating as shown in FIG. 1 and without an embossing pattern. The second variant then had, in addition to the abrasive coating, a rod-shaped embossing pattern as shown in FIG. This means that the two variants of washcloth 3 differ only in the presence of the rod-shaped embossing. Laundry cloth 4, like laundry cloth 3, had the abrasive coating from FIG. 1 and was not embossed (that is, with regard to the surface properties, it was designed like the first variant of laundry cloth 3). The values for the coefficients of friction shown in FIGS. 5a to 5d clearly relate to the laundry towels with the surface properties described above (and not just to their base material without any coating or embossing). As already mentioned, the results show that an embossed pattern can improve the sliding behavior of the laundry towels according to the invention, in particular in the transverse direction.
