Definitions

  • the present invention relates to a mop yarn device for a floor mop comprising a flexible web-shaped carrier means, to the one surface of which a great number of mop threads are attached for cleaning purposes and the oppo- site surface of which is intended for releasable attachment to the frame of the floor mop, e.g. by means of Velcro strip.
  • the invention relates to a mop yarn device, i.e. the active, cleaning component of a mop system.
  • This mop system comprises a floor mop carrying the mop yarn device, said floor mop mainly consisting of a mop frame having a pivotable handle attached thereto, for instance as stated in Swedish patent specification 504,242.
  • the mop yarn device can be releasably attached to the mop frame by means of Velcro strip.
  • the mop system also comprises a board for care and maintenance of mop yarn for facilitating the cleaning of the mop yarn device, which is disclosed in Swedish patent specification 504, 113.
  • the mop yarn device according to the invention is mainly intended for use in connection with dry cleaning methods, in which water is essentially used only to remove stains and which constitute the most efficient way of dramatically reducing the use of chemicals in cleaning activities, but the mop yarn device is, of course, equally useful in connection with wet cleaning methods, which must be applied when the floors are dirty due to wet dirt or dirt in solid form which has been wet.
  • wet cleaning methods which must be applied when the floors are dirty due to wet dirt or dirt in solid form which has been wet.
  • dry cleaning methods are less strenuous for the cleaning personnel because of the lower friction between the mop and the floor surface.
  • the present mop system is particularly suited for the cleaning of public areas, and the pollutants in these areas mainly consist of loose particles, such as sand, dust, skin deposits, hair, shreds of clothes etc.
  • loose particles such as sand, dust, skin deposits, hair, shreds of clothes etc.
  • wet cleaning methods big quantities of these loose particles are "smeared" over the floors by means of remaining water, which subsequently dries up, and are released as dust again. Since most cleaning in public areas is made in the daytime, wet cleaning surfaces cannot be shut off during the drying, and this results in the floors to a large extent being resoiled since the personnel have to step on the wet floors, which releases dirt from the shoes sticking to the floors.
  • Damp or wet mops and swabs are very heavy and hard to move back and forth over the floors and this is the main reason for the great number of notifications of illness and industrial injuries, which constitutes a burden to the cleaning trade. This often results in too frequent changes of personnel. Moreover, a tired cleaner achieves a lower working performance.
  • the surface layer of the floors is damaged by frequent use of cleaning chemicals since the floor surfaces are "roughed up” and become coarser and more lustreless and liable to take up dirt.
  • the object of the present invention is therefore to provide a mop yarn device with little friction against the floor surface which is cleaned with a view to facilitating the cleaning work.
  • Another object of the invention is to provide a mop yarn device, which can efficiently release dirt particles from a floor surface and also catch and retain the dirt particles.
  • a further object is to provide a mop yarn device which can efficiently catch and retain pieces of fluff.
  • a mop yarn device as mentioned by way of introduction, which is characterised in that the mop threads consist on the one hand of tightly and, on the other, of loosely plied bundles of natural fibres, which have a comparatively smooth surface structure, such as flax fibres, that the mop yarn device comprises a central portion with mop threads of comparatively small length and a peripheral portion with mop threads of comparatively great length, and that the loosely plied mop thread bundles are located only in said central portion whereas the tightly plied mop thread bundles are located in said central portion as well as in said peripheral portion.
  • Fig. 1 is a perspective plan view of the floor mop device according to the invention showing its carrier means with the surface intended for releasable attachment to the frame of a floor mop,
  • Fig. 2 is a perspective bottom view showing the opposite surface of the carrier means, to which surface the mop threads are attached, and
  • Fig. 3 is a vertical cross-section of the mop device along the line A-A in Fig. 2.
  • the inventive mop device comprises ⁇ flexible, web- shaped carrier means 1 of a suitable, long-wearing fabric, which is washable a number of times without losing its shape and which is resistant to cleaning chemicals.
  • carrier means are known per se and velour fabric is an example thereof.
  • This is also prior-art and reference is made to the Swedish patent specifications mentioned above.
  • mop threads of yarn are attached, as usual, for cleaning purposes, i.e. the function of the mop threads is on the one hand to release the dirt or the dirt particles from the (floor) surface to be cleaned and, on the other, to catch and retain the dirt and the dust in the mop yarn device.
  • mop threads consist of plied bundles of fibres, such as cotton and/or synthetic fibres, but the fibres of the mop threads of the present mop yarn device consist of quite different fibres, as will be discussed below.
  • Cotton yarns are as a rule compact and not particu- larly active in transporting the dirt towards the carrier means. Furthermore, cotton yarns have a tendency to let fluff come off and felt, which has an adverse effect on the cleaning work. In addition, the individual cotton fibres are not efficient in the scraping off of dirt from the floor surface. Finally, the production of cotton as such is not environment-friendly.
  • flax fibres This natural fibre has a smoother or glossier surface than that of the cotton fibre, which results in less friction and improves the scraping off of dirt from a surface. Further, in this connection the flax fibre has a longer working life than the cotton fibre and a higher tensile strength. Indeed flax is more expensive than cotton, but this is compensated for by a longer working life. Finally, the manufac- turing of flax is better than that of cotton from an environmental point of view.
  • the inventior. is not, however, limited to flax fibres only but it also comprises all natural fibres having a comparatively smooth surface structure, e.g. hemp, sisal and others. Flax fibres are available in coarse or fine bundles, consisting of many or few fibre units joined together or completely separate fibre units.
  • pectin substances are removed from the foliage and the fibre units are sepa- rated.
  • the flax harls are boiled under pressure in a solution of 2-2.5% lye for a few hours.
  • the fibres of cottonised flax are short and stiff. They must be spun in combination with e.g. cotton or viscose.
  • the tensile strength is lower than that of ordinary flax, but higher than that of cotton yarns.
  • Blend yarns with cotton are devoid of the usual compactness and tendency of cotton to let fluff come off and felt.
  • Flax yarn is strong in its longitudinal direction compared to other natural fibres, but has a low extension capacity. The flax fibres are, however, sensitive to wear and breaking forces.
  • the yarn of a mop system is exposed to great strain throughout its working life.
  • the yarn is exposed to mechanical treatment by wear, traction and bending during both direct use and washing/drying.
  • the wear weakens the fibres and makes them break, which results in deposits of lint and loose fibres. Once the wear has started, there is an increased number of free fibre ends, which in their turn are exposed to wear with an additional risk of fibre loss.
  • non-cottonised flax is used having a great fibre length since long fibres offer less friction and short fibres are more liable to break.
  • they are impregnated with a vegetable oil which is environment-friendly, preferably rape-oil.
  • rape-oil When the mop threads are intended for domestic use, it can be con- venient to use the mop threads moistened with water instead of impregnated with oil, which is an advantage when subsequently cleaning the mop yarn device, for instance, by means of an ordinary washing machine.
  • the mop threads can also be dyed or ingrained.
  • a yarn of fine fibres is more flexible than a corresponding one of coarse fibres. Fine fibres are, however, light and liable to be more unruly. A yarn of coarser, heavier fibres can be more adaptable to the floor surface. A yarn of fine fibres has a larger fibre surface than yarn of coarse fibres. A yarn of fine fibres can therefore hold more oil or dirt particles between the fibres of the yarn, if the yarn is not tightly plied. Very fine fibres can be difficult to clean depending on how the dirt particles are bound to the material. In general, coarse fibres are cheaper than fine. A yarn of somewhat coarser flax fibres is fully sufficient for the purpose in question. The shape of the yarn itself is more important to the function of the mop.
  • the mop yarn device comprises a central portion 3, which is located inside the periphery of the carrier means 1, and a peripheral portion 4, which is located outside the periphery of the carrier means; in particular cf. Fig. 3.
  • mop threads 5, 6 of the same length are attached to the carrier means 1, whereas mop threads 7 of greater length than the mop threads 5, 6 are protrudingly attached to the carrier means in the peripheral portion 4.
  • the mop threads 5 and 7 are relatively tightly plied or laid to offer less friction against the floor surface, whereas the mop threads 6 are relatively loosely plied or laid to increase the dirt and waste collecting capacity.
  • the mix of the mop threads 5 with the mop threads 6 in the central portion 3 reduces the friction of the floor mop against the floor and facilitates the cleaner's work.
  • the mop threads 5-7 are preferably attached to the carrier means in the form of closed loops, which is clearly shown in the Figures.
  • the mop threads 5- 7 are attached to the carrier means 1 by means of mutually parallel seams 8, which are arranged at a considerable distance from each other so that the pile will not get so thick that the insertion of dirt etc. towards the carrier means is at risk.
  • each seam 8 is also expedient to make each seam 8 as two parallel lines of stitches 9 to better secure the threads 5-7 and better spread the thread loops.
  • the arrangement above also makes it possible to attach each individual mop thread 5-7 to the carrier means 1 in an unbroken or continuous condition, i.e. as a continuous thread by means of, and along, the entire associated seam 8, which considerably facilitates the manufacturing of the mop yarn device.
  • the mop yarn device stated above can, when required, be cleaned by means of the board for care and maintenance of mop yarn which is stated in Swedish patent specification 504,113 mentioned above. Occasionally, the mop yarn device must, however, be subject to a more thorough cleaning by washing.
  • the design of the mop threads makes them open up somewhat more and the thread loops to be randomly oriented, i.e. they extend in all directions.
  • the cleaning function of the mop yarn device is further improved.
  • the inventive mop yarn device has also been tested against other prior-art mop yarn devices and different floor materials. The result of the test is stated below.
  • Test material 1. mop with a large portion of synthetic yarn
  • the floor materials consisted of
  • a friction measure was determined by a test according to a modified TEFO-method 18-66.
  • the test is carried out by placing a mop sample on a floor material. A weight of 1.5 kg is applied to the mop sample to simulate the pressure of the mop when cleaning.
  • the mop sample is attached to a load cell, which itself is connected to a tensile tester.
  • the floor material is moved in relation to the mop at a constant rate. The static and dynamic friction force is registered. Each mop variant was tested against two floor samples.
  • Test size a mop of 16 cm in full width, edges excluded.
  • *N is the normal force (the force of the mop against the base)
  • F mean /N is a measure of the dynamic frictional coefficient .
