Definitions

• the invention relates to a cleaning article according to the preamble of patent claim 1.
• Cloths for example of viscose materials, in particular nonwoven fabrics or sponge cloths are usually provided with a flexible printing.
• a printing paste is applied in liquid form and then dried by the action of heat with the aid of a dryer.
• the printing usually takes place directly after the production of the material from which the cloth is made.
• the invention is therefore based on the object cost-effectively to provide a cleaning article with a cloth-like body with a print that has a distinctive character and is well fixed on the surface, the printing without the use of a dryer and therefore low energy consumption and low space requirements during the assembly of the body can be applied to this.
• the present invention achieves the aforementioned object by the features of patent claim 1.
• An inventive cleaning article has a cloth-like,
• deformable body on which has a printing.
• the printing consists of a hot-melt adhesive.
• the object is achieved by using a so-called hot-melt adhesive.
• the hot-melt adhesive according to the invention is designed as a print pattern and / or printed lettering. It can be advantageously distributed on a sheet goods. It is advantageous that the hot-melt adhesive in a hot state, preferably at a temperature of 80 ° C to 160 ° C, can be applied to the web material and solidifies on cooling.
• the hot-melt adhesive is surprisingly sufficiently firmly fixable on the web, so that the sheet goods can be folded, cut and packaged.
• a chemical post-crosslinking can take place according to the invention without the use of a dryer in the packaging of the cleaning article.
• the chemical postcrosslinking used there is for the connection of the
• a hot-melt adhesive is used not just as an adhesive but as a means of producing a pattern, writing or logo on the surface of a cleaning article.
• a cleaning article is provided with a cloth-like body cost with a print that has a distinctive character and is well fixed on the surface, the printing applied without the use of a dryer and therefore with low energy consumption and low space requirements during the assembly of the body on this can be. Consequently, the object mentioned above is achieved.
• the hot-melt adhesive could be designed as a polyurethane hot-melt adhesive.
• Polyurethane is particularly stable to washing and permanently fixable to the body.
• the polyurethane hot melt adhesive could be designed as a one-component polyurethane adhesive. This is a simple one
• the hot-melt adhesive could have a viscosity in the range from 3000 to 20 000 mPas, preferably 9000 to 18000 mPas, in a temperature range from 80 ° C to 160 ° C, preferably at 130 ° C. At 3,000 to 20,000 mPas, the hot-melt adhesive penetrates particularly well into the body. At 9000 to 18000 mPas, the hot-melt adhesive solidifies very quickly on the base body, making it easy to process.
• the cloth-shaped body could be designed as a sponge or as a sponge cloth. An open-celled sponge can absorb a great deal of fluid from a surface to be cleaned. A closed-cell sponge is highly elastically compressible due to its porosity, but absorbs only very little liquid and can therefore protect a surface to be cleaned from too much moisture.
• the main body could be made of a non-woven or have a fleece.
• Nonwovens or nonwovens can be manufactured inexpensively. This can be made very tear-resistant and thin cloths.
• the main body could be provided with a full-surface coating, on which the print is applied.
• the coating solidifies the nonwoven or the nonwoven fabric. The coating helps remove one
• Nitrile butadiene rubber manufactured.
• PVA is particularly absorbent, latex is particularly cost-effective.
• the main body could be made of viscose or have viscose. Viscose includes cellulose and is therefore an environmentally friendly material based on renewable raw materials.
• the printing could be designed as projecting from the main body or outstanding, raised structure. As a result, the cleaning article can develop a very good cleaning performance.
• a sublime character of the printing is understood to mean a sublime structure thereof.
• a method of making a cleaning article of the type described herein could include the steps of providing a material from which a cloth-like body can be made and printing the material with a hot-melt adhesive.
• the material could be printed while wet. Surprisingly, wet materials can be printed with the hot-melt adhesive without first drying them. The hot-melt adhesive sticks surprisingly well to wet material.
• the material could be used as web material, preferably in longitudinal or
• Transverse direction process and be printed simultaneously during the process. Simultaneous execution of two production steps can save costs. Furthermore, the liquid hot-melt adhesive can be quickly distributed on the material or the web goods.
• the material used could be a magnesium chloride soaked sponge or viscose sponge.
• the cleaning article could in this case be designed as a sponge cloth. It is advantageous with the printing of a magnesium chloride impregnated cloth-like cleaning article, especially a sponge cloth, printable without drying it before.
• Embodiment 1 Embodiment 1
• a cleaning article with a cloth-shaped basic body of viscose was printed with a polyurethane hot-melt adhesive of the type AdtraPUR XPC 148.1 Red from Adtracon GmbH, 40721 Hilden, Germany.
• the polyurethane hot-melt adhesive was applied at a temperature of 130 ° C. to a sheet material from which the cleaning article was made up.
• the web goods were thereby moved at a speed of 50 m / min in the web direction. It was surprisingly found that the polyurethane hot-melt adhesive cures physically so quickly that the web material can be rolled up or folded after printing, without the printing being flattened and losing its distinctive character.
• a bonding of individual rolled-up or folded web goods sections surprisingly did not take place, so that the web goods can be unrolled or unfolded without damage. Surprisingly, these process steps could be carried out at high speed and low cure distance for the web goods.
• a chemical post-crosslinking of the polyurethane hot-melt adhesive takes place within a few hours to days. As a result, the printing was stable against abrasion and washing loads. The cleaning article can be easily washed 10 times at 60 ° C with a conventional detergent, without the printing peels off.
• the polyurethane hot-melt adhesive is designed as a one-component polyurethane adhesive. It comprises a polyurethane prepolymer with isocyanate groups. It contains 4, 4 '- methylene diphenyl diisocyanate. It has a density of 1, 1 - 1, 3 g / cm 3 at 20 ° C and is insoluble in water.
• Embodiment 2 is a diagrammatic representation of Embodiment 1:
• a cleaning article with a cloth-like main body of nonwoven fabric was printed with a polyurethane hot-melt adhesive of the type XPC 023.021 (5117 red) from Adtracon GmbH, 40721 Hilden, Germany.
• Exemplary Embodiment 3 A cleaning article having a cloth-like main body of viscose was printed with a polyurethane hot-melt adhesive of the type XPC 020.02 (red) from Adtracon GmbH, 40721 Hilden, Germany.
• a cleaning article with a cloth-shaped viscose body was printed with a polyurethane hot-melt adhesive of the type XPC 178.002 (red) from Adtracon GmbH, 40721 Hilden, Germany. The printing was applied to a base body which acts as a wet sponge or
• Sponge cloth was designed, which was impregnated with magnesium chloride.
• the hot-melt adhesive may be applied to the body by a spray, rollers, stencils or rotating means.
