Definitions
- the washcloth in particular the base material, can have a weight per unit area of 40 g / m 2 to 400 g / m 2 .
- 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.
- 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 .
- 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 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.
- the aforementioned values relate in particular to the floor wipe.
- 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 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.
- 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.
- 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
- 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 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 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 maximum degree of impregnation is given as the mean value from three determinations.
- 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”)
- the floor area wiped up to that point is the area performance.
- 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.
- Test for 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.
- BAC benzylalkyldimethylammonium chloride
- silica gel RP-8 (column from Macherey-Nagel, designation "150 / 4.6 Nucleodur 100-5 C8 ec"; heated to 40 ° C)
- 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:
- 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 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.
- n 2 per washcloth (1 x lengthways, 1 x transversely)
- Microfibers microfibers
- 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.
- 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.
- 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.
- 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.
- 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).
- EVA ethylene vinyl acetate
- 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.
- 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.
