Definitions

  • the invention concerns a cotton swab for cosmetic or medical purposes or for body care, comprising a stick, at least one end of which is provided with a fiber material forming a cotton head.
  • Cosmetic or medical cotton swabs of this type serve to clean, remove make-up or apply cosmetic products or in the medical field, to clean wounds or apply ointments.
  • EP 0 402 140 B1 discloses a cotton pad comprising a cotton head of lipophilic polyolefin microfibers.
  • microfibers is largely undefined.
  • EP 0 363 533 A1 describes a cotton swab whose fiber material comprises cotton fibers and thermally meltable bi-component fibers whose portion is defined, by way of example, to be at least 10 weight %. This document does not provide any further information.
  • DE 101 23 971 C2 discloses a cleaning stick for cleaning electrical or electromechanical components. It has a pointed end which is surrounded by a piece of cloth, following the conical shape of the stick, to thereby produce a sealed conical end on a cleaning stick.
  • the material may be a woven polyester or, alternatively, a polyester nylon microfiber material.
  • U.S. Pat. No. 4,100,324 describes a fiber mixture of wood pulp fibers and thermoplastic microfibers having an average fiber diameter of less than 10 ⁇ m. Due to the fact that this fiber mixture is essentially produced simultaneously with spinning of the microfibers by introducing an air flow and a pulp fiber flow into the region of the spinning head for the microfibers, the fibers are connected and the microfibers fix the pulp fibers in a state in which the microfibers are still at increased temperatures and not yet solidified.
  • the microfibers therefore have a matrix-forming effect on the wood pulp fibers, and embed the wood pulp fibers in a hinged, i.e. non-rigid, manner even for very small microfiber content of down to 1 weight %.
  • Further fibers or particulate material may be introduced, including synthetic fibers such as nylon fibers or natural fibers such as cotton, flax, jute and silk.
  • microfibers Due to the production of the fiber mixture substantially in situ together with formation of microfibers using the melt blown method, the microfibers lose their independence in the fiber product and are modified and fixed while soft by means of the contact to the wood pulp fibers. They can no longer be used as an individual fiber component or as fiber type for producing a product i.e. for introduction into a production process.
  • the combined flow of melt blown microfibers and wood pulp fibers is introduced into a gap between two vacuum rollers and formed into a fleece having a very high weight per unit area of 50 g/m 2 to nearly 200 g/m 2 .
  • the fiber mixture has attained its final fleece shape directly following fleece formation. Subsequent fraying out, i.e. separation of the fibers is no longer possible.
  • the fiber material comprises micro staple fibers having a length of at least 7 mm.
  • micro staple fibers used above means synthetic fibers of a fiber strength of ⁇ 1 dtex.
  • micro staple fibers thereby means that microfibers of a defined length or defined length range are used for producing the fiber fleece layer or a band or cord-shaped fiber fleece for the cotton head at the free ends of the cotton swabs, the fibers having been previously formed in a separate production method. These separated staple fibers are then deposited to form the fiber material. Fibers formed by spinning fleece or melt blown methods, with (see U.S. Pat. No. 4,100,342) the fiber forming and fleece forming processes being essentially carried out in one step, are not used.
  • microfibers of a certain length or of a certain length region are used which are formed in a production method which is separate from the fleece forming process. It has turned out that synthetic micro staple fibers can provide a cotton swab or the cotton head of a cotton swab with more softness and therefore with an excellent haptic effect for the user while surprisingly not reducing the cleaning or make-up removing effect or the solidity of the cotton head.
  • inventive cotton swabs having micro staple fibers of a length of at least 7 mm actually have superior cleaning and make-up removing effect and are better suited to e.g. remove fat-containing dirt from the ear than are cotton swabs which consist of 100% cotton fibers.
  • the available surface of the fiber material which can come into contact with the skin surface to be cleaned is also larger compared to pure cotton swabs. This large surface therefore also delimits a large number of microgaps and openings which may serve to receive impurities, skin particles, fat-containing dirt or make-up.
  • the length of the micro staple fibers which can be used is preferably 10 to 38 mm, in particular, 15 to 32 mm.
  • the micro staple fibers may be polyester (PES) or viscose fibers.
  • the portion of micro staple fibers relative to the mass of the fiber material is preferably 3 to 50 weight %, in particular 5 to 30 weight % and most preferably 5 to 20 weight %.
  • the fiber material may additionally advantageously comprise up to 97 weight %, in particular 60 to 97 weight % and preferably 70 to 95 weight % of cotton fibers.
  • Cotton fibers are advantageously included, in particular, when the cotton swab should be suited to receive a face-cleaning solution or to remove make-up using a make-up removing agent having a high liquid portion.
  • Cotton noils are preferably used as cotton fibers.
  • the synthetic micro staple fibers produced in a separate process are deposited to form fleece in accordance with conventional fleece formation methods. If different fiber types are used, these are preferably previously mixed in an air flow and then deposited. If additional thermally meltable binding fibers are present, the fleece may be thermally fixed in an “air-through-method” with a precisely adjustable gas temperature, thereby preferably preventing thermal and thereby structural influence or impairment of the synthetic micro staple fibers.
  • the fiber material advantageously comprises thermally meltable binding fibers.
  • the portion of thermally meltable binding fibers compared to the mass of fiber material is, in particular, 5 to 20 weight % and preferably 5 to 15 weight %.
  • the binding fibers may be multi-component fibers, in particular, bi-component fibers, having a carrier component which melts at higher temperatures and a binding component which melts at lower temperatures.
  • the multi-component fibers in particular, bi-component fibers advantageously have a fiber thickness of 1.3 to 10 dtex, in particular 1.3 to 3 dtex and a fiber length of 3 to 60 mm.
  • Advantageously core/jacket fibers or side-to side fibers are used.
  • Bi-component fibers having a copolyester (CO-PES) as low melting component and polyester (PES) as higher melting component have turned out to be advantageous.
  • the melting point of the thermally meltable binding fibers or the low melting component (e.g. CO-PES) of the multi-component fibers is lower than the melting point of the micro staple fibers.
  • Micro staple fibers of polyester material may e.g. be used having a melting point of approximately 256° C. and CP-PES/PES bi-component fibers having a melting point of the low melting component CP-PES of 110° C. and of the higher melting component PES of 255° C.
  • the fiber fleece may be thermally solidified to produce the cotton head without thermally changing the higher melting component of the bi-component fibers and the micro staple fibers.
  • the removing resistance of the fiber material forming the cotton head which represents a measure for the binding of the fiber material to the free end of the stick and also for the fiber adhesion, is at least 30 N, preferably at least 40 N, as measured in accordance with the following removal test.
  • the removal resistance or the peeling-off resistance of a cotton head during removal from the free end of the stick of a cosmetic or medical cotton swab is determined using the following removal test.
  • a sample holder 2 FIG. 1
  • a tensile testing device 3 FIG. 2
  • the sample holder 2 comprises a holding block 4 with a bore 6 whose diameter is slightly larger than the outer diameter of the stick 8 of the cotton swab.
  • the diameter of the bore 6 is thereby 3 to 5% larger than the outer diameter of the stick 8 of the cotton swab such that even with a tolerance for the outer diameter of the stick of ⁇ 3%, the stick region of the cotton swab can still be slidably reciprocated in the bore, substantially without resistance.
  • the cotton head is separated from a cotton swab on the side which is not tested and this free end of the cotton swab is inserted through the bore 6 of the holding block 4 .
  • the sample holder 2 comprising the swab to be tested is clamped in the tensile testing device 3 ( FIG. 2 ).
  • the free end 10 of the cotton swab which is disposed through the sample holder 2 is thereby fixed in the lower clamp 12 of the tensile testing device 3 ( FIG. 2 ).
  • the sample holder 2 itself is fixed in the upper clamp 14 of the tensile testing device.
  • the tensile testing device is adjusted such that the clamps 12 , 14 move apart with a testing speed of 300 mm/min, wherein the upper clamp 14 is moved away from the stationary lower clamp 12 at the testing speed, as shown.
  • the testing force which acts between the clamps is thereby measured.
  • the maximum tensile force determined during testing is rounded off to a decimal and stated in Newtons.
  • Each test terminates by shearing the stick 8 of the cotton swab from the cotton head 16 and pulling it through the bore 6 of the holding block 4 of the sample holder 2 .
