Definitions

  • the invention relates to a cleaning cloth made of a flat, non-woven fleece material with an underside and an upper side comprising absorbent natural fibers and synthetic melt-binding fibers, with a region-wise, not full-surface coating being provided on at least one side, which gives the cleaning cloth increased cleaning power.
  • cleaning articles eg for surface cleaning, in particular known for household cleaning, as well as for skin cleansing, in particular for facial cleansing.
  • a cleaning cloth is eg in the WO 2017/081285 described, which deals with the design of the coating lines.
  • the invention solves this problem with a cleaning cloth having the features of claim 1 and a method having the features of claim 14.
  • a cleaning cloth or cleaning article or wiping cloth is intended in particular to mean cleaning articles for cleaning surfaces or objects (surfaces), such as in particular cleaning cloths, for example for household purposes or floor cleaning, but also in the kitchen or sanitary area , as well as to Pane and window cleaning etc. are understood.
  • cosmetic cleaning articles such as, in particular, cosmetic pads and cosmetic tissues should also be included.
  • the cleaning articles can differ in terms of shape, size or thickness.
  • the cleaning cloth is particularly preferably a floor cleaning cloth, ie a cleaning cloth which is intended for floor cleaning.
  • the natural fibers or natural fibers are naturally occurring and not chemically modified fibers or fibers consisting of natural polymers that have not been chemically modified.
  • the natural fibers are absorbent. Cellulose and in particular cotton are particularly preferred here, since cotton has a good storage and absorption capacity for liquids.
  • other natural fibers can also be used, such as flax, abaca, hemp or ramie.
  • the fusible binder fibers 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".
  • synthetic fusible binding fibers are also provided in the fiber mixture. They can be brought into a melted and (partially) flowable state by the influence of heat, which enables partial embedding and bonding of other fibers.
  • the fusible bonding fibers can give the cleaning sheet strength required for wiping and cleaning.
  • the fusible binding 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 jacket is formed by the low-melting component.
  • the core is formed by the higher melting point component.
  • the fusible bond fibers can be made from polyesters, polyolefins (such as polypropylene or polyethylene), polyamides, or blends thereof.
  • the melt-bonding fibers preferably consist of polyesters, in particular polyethylene terephthalate (PET) and polyethylene terephthalate-co-isophthalate.
  • PET polyethylene terephthalate
  • 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 by the copolymer will.
  • the core described above could then be formed from the PET.
  • the cleaning cloth results from the preferably provided synthetic microfibers.
  • the microfibers allow the cleaning cloth to pick up dirt better and improve its cleaning performance.
  • the microfibers can have a fiber fineness of 1 dtex or less, in particular 0.9 dtex or less. The finer the fibers, the better the cleaning performance of the cleaning cloth.
  • the microfibers can be made of a polyester, a polyolefin (such as polypropylene or polyethylene), or a polyamide.
  • microfibers preferably consist of a polyester, in particular polyethylene terephthalate.
  • the strength is further significantly improved in that the cleaning cloth has an embossing with raised, unembossed areas and lower-lying embossed areas on at least one side. Embossing creates unembossed areas between the embossed areas that are less dense. The embossing further strengthens the surface, making it more difficult for fibers to be pulled out. Furthermore, the lower-lying, embossed areas prevent the wiper from adhering to the surface to be cleaned over the entire surface, which reduces friction and consequently leads to improved sliding properties of the wiper. In the unembossed areas, the high liquid absorption of the fiber mixture is fully retained.
  • the fusible binding fibers and the embossing therefore serve to make the cleaning cloth stable and resistant, so that it remains intact when wiping and cleaning and has good sliding properties.
  • Underlying is to be understood as meaning a region that is set back or pressed into the material with respect to the unembossed surface.
  • Another advantage of the cleaning cloth according to the invention is that it can be produced comparatively inexpensively and has a high proportion of renewable and biodegradable material in the form of natural fibers, in particular cotton.
  • the cleaning cloth has an abrasive coating.
  • the abrasive coating is usually applied to the fleece material, for example using a gravure printing process.
  • the abrasive coating can be applied to only one side or to both sides of the fleece material.
  • the abrasive coating is preferably designed in the form of strips or lines, with the strips or lines advantageously also being able to be patterned, for example in 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 using a microscope. The extent of the coating is related to the height meant perpendicularly to the direction of the areal extension of the cleaning cloth.
  • 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-
  • the abrasive coating comprises or consists of ethylene vinyl acetate (EVA).
  • EVA ethylene vinyl acetate
  • the material of the abrasive coating also preferably has a Shore A hardness from 50 to 100, in particular from 70 to 100, determined according to DIN 53505:2000-08 and ISO 868:2003(E).
  • the cleaning cloth essentially consists of the fleece material.
  • the cleaning cloth then mostly consists of the non-woven material, the abrasive coating, optionally a liquid detergent (in the case of a pre-moistened cleaning cloth) and optionally a suture material (if the cleaning cloth is sewn as described below) to make it into a cleaning supplies to assemble, which interacts with a wipe holder, for example.
  • Nonwovens can be produced comparatively easily and cheaply.
  • the fleece material is usually reinforced by needling using high-pressure water jets (spunlace process). This can reduce the tendency to fuzz on the surface.
  • the nonwoven material is normally consolidated by partial melting of the fusible bonding fibers. The tear strength of the fleece material can thus be adjusted.
  • the embossed areas take up at most 50% of the total area of the embossed side, in particular at most 40%, more particularly at most 30% and in particular at least 6%, in particular at least 8% and more particularly at least 10% and more particularly at least 15% %.
  • a sufficient strengthening of the surface is achieved by the embossed areas and, on the other hand, a sufficient area of unembossed areas is provided, which allow liquid absorption in a particularly advantageous manner.
  • a good balance between liquid absorption and sliding properties of a corresponding fleece material and a cleaning cloth made from it is provided.
  • the embossing of the fleece material is preferably designed as a pattern.
  • the fleece material therefore has an embossed pattern.
  • the pattern order ensures a defined provision of the embossing.
  • the embossing pattern is preferably designed in the form of a lattice, a diamond, a rod or a honeycomb.
  • the rod-shaped design of the embossing pattern is preferred in the present case, or the design of embossing lines in a non-continuous manner.
  • the non-woven material is usually provided with the embossed pattern essentially over its entire extent.
  • the embossed pattern can be formed, for example, by indentations on the side of the fleece material intended for cleaning, the indentations being made in the fleece material, for example, with a corresponding embossing roller.
  • the embossing pattern is created in the fleece material by means of a hot calender. A particularly durable embossing can be achieved in this way.
  • the embossing and the coating have a synergistic effect and complement each other in terms of their cleaning properties. It can be particularly preferred that the embossed areas and/or the coating is arranged in patterns, in particular patterns distributed evenly over the entire page.
  • the embossing and the coating are particularly preferably arranged on the same side of the fleece material, so that the abrasive properties are combined with the good sliding properties.
  • the embossing and coating are not formed as congruent patterns and in particular are not formed from parallel lines. This ensures that the coating does not lose its effect because it comes to rest in larger areas in the embossing and thus no longer rises above the base area.
  • the coating should not be more than 30%, in particular not more than 20%, in particular not more than 10%, in particular not more than 5%, in particular not more than 3% of its proportion in an embossing line. In this way the effect of the coating would be overridden or at least reduced.
  • the embossing can also preferably be in the form of a line, for example in the form of a lattice, with the lines preferably being in the form of rods or dashed or dash-dotted. With regard to the pattern of the embossing and the design of embossing lines, what is stated below with regard to the pattern and line design for coating can also apply.
  • the fleece material can have a thickness of 1.5 to 7 mm, in particular 2 to 4 mm, in the area of the raised areas, ie in the area of the non-embossed areas, at a pressure of 0.5 kPa.
  • the fleece material in the area of the lower-lying, embossed areas, can have a thickness that is 0.1-0.6 mm, in particular 0.1-0.3 mm, less than that of the raised areas at a pressure of 0.5 kPa. This means that the depth of the lower-lying embossed areas in relation to the thickness of the raised areas can be 0.1-0.6 mm, in particular 0.1-0.3 mm, at a pressure of 0.5 kPa.
  • the values given for the thickness refer to the dry, single-layer (i.e. not laid together or on top of one another) fleece material.
  • the thickness of the non-woven material can be determined using a specific measuring pressure of 0.5 kPa on a probe area of 25 cm 2 .
  • a DMT thickness gauge from Schröder can be used. Otherwise, the thickness can be determined based on DIN EN ISO 9073-2: 1995.
  • the cleaning cloth in particular the fleece material, can be essentially rectangular in shape and have a length of 10 cm to 60 cm and a width of 10 cm to 60 cm.
  • 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.
  • a floor wipe it can advantageously have a length of 40 cm to 60 cm, in particular about 43 cm, and a width of 10 cm to 20 cm, in particular about 13 cm.
  • the preferred strip-like shape of the floor wiping cloth fits the wiping cloth holders of conventional wiping mop systems. In the case of floor wipes for wipe holders, provision can be made for the material of the cleaning cloth to be doubled at least in some areas on the two shorter sides and sewn or welded to form pockets into which a wipe holder can then engage.
  • the coating density and/or embossing density should be determined using an imaginary grid, whereby a grid with parallel, equidistant, perpendicular lines with an edge length of 7 mm of each grid square is understood to mean such an arrangement of lines in which a group of parallel, equidistant lines is intersected by a second set of parallel, equidistant lines forming right angles.
  • a grid with parallel, equidistant, perpendicular lines with an edge length of 7 mm of each grid square is understood to mean such an arrangement of lines in which a group of parallel, equidistant lines is intersected by a second set of parallel, equidistant lines forming right angles.
  • At least 5 grid squares per 25 cm 2 should have a first degree of coverage of coating and/or embossing of at least 15% and thus a high degree of coverage and at least 5 grid squares per 25 cm 2 have a second degree of coverage of coating and/or embossing of at most 8% and thus a comparatively low degree of coverage.
  • first degree of coverage of coating and/or embossing of at least 15% and thus a high degree of coverage
  • at least 5 grid squares per 25 cm 2 have a second degree of coverage of coating and/or embossing of at most 8% and thus a comparatively low degree of coverage.
  • the specification "per 25 cm 2" is understood as a reference value. In the evaluation, the entire side surface of the cleaning cloth is considered. In the case of cleaning cloths with a smaller or larger dimension deviating from 25 cm 2 , the number of grid squares determined on the first side surface of the cleaning cloth with the first and second degree of coverage is correspondingly normalized and converted to 25 cm 2 .
  • the degree of coverage is understood to mean the area covered by the coating and/or embossing within a grid square, based on the area of the grid square.
  • any evaluation method e.g.
  • a cleaning cloth which, due to areas with a relatively high degree of coverage, has a large coating density and/or embossing density, in particular a large Coating density and/or embossing density at coating lines and/or embossing lines, has a good dirt cleaning effect and good sliding properties.
  • a cleaning cloth offers a sufficient absorption or holding surface for the components released from the surface to be cleaned, such as dirt particles or moisture, due to a likewise large number of areas that only have a small degree of coverage.
  • Such absorption or receiving surfaces can then also simultaneously have a certain softness compared to hard surfaces if, for example, a household towel is to be implemented.
  • the coating and/or embossing of the cleaning article preferably includes coating lines and/or embossing lines.
  • a full-surface coating of the cleaning cloth in the sense of a continuous, area-wide, uninterrupted application is not provided.
  • partial areal coatings and/or embossing or punctiform coatings and/or embossing can also be provided.
  • Linear coating and/or embossing means in particular an element in which a line width of at least 0.2 mm is provided and the line has a length that is at least five times the line width.
  • the linear coatings and/or embossing can have both straight lines and curved lines, as well as intersecting straight or curved lines.
  • the lines can be either continuous or interrupted at least in certain areas, provided the line remains clearly recognizable as such.
  • dashed (rod-shaped), dash-dotted or dotted coating lines are also conceivable within the meaning of the present invention.
  • the broken points may not be longer than ten times, in particular no longer than eight times, in particular no longer than six times, in particular no longer than four times the line width of the line adjacent to the broken point.
  • Grid, honeycomb or diamond-shaped patterns consisting of coating lines and/or embossing lines are particularly preferred.
  • the coating and/or embossing covers the cleaning cloth and here in particular the first side surface (top or bottom) essentially over its entire extent, i.e. not just special areas such as the middle or outer area of the cleaning cloth. It is therefore preferably provided that the coating and/or embossing extends over the entire at least first side surface of the cleaning cloth, with individual areas of the cleaning cloth, such as the central or edge area, depending on the pattern provided, being within the scope of the present invention in terms of pattern density may vary. It is also conceivable to apply different patterns in some areas of the cleaning cloth than in other areas. For example, a different coating or embossing can be provided in the central area than in the edge area.
  • the cleaning cloth has a coating and/or embossing on the first and second side surface. This means that the cleaning cloth can be used by the user for more intensive cleaning processes can be used regardless of the orientation of the cleaning cloth.
  • the coating features and/or embossing features can be designed differently or the same in terms of their geometric shape and/or their dimensions on the upper and lower edges.
  • the various properties of the cleaning article such as the degree of coverage, frictional force, absorption properties, etc., can be taken into account and implemented by adjusting the coating and embossing patterns.
