Definitions

  • the present invention relates generally to synthetic filaments. More particularly, the present invention relates to a crimped synthetic filament having a mildly abrasive additive such as clay and a chemically tipped filament end.
  • synthetic filaments can overcome many of the problems of natural bristles, and various attempts have been made to replace natural bristles with synthetic.
  • synthetic filaments has also met with difficulties. Synthetic bristles do not have the softness, texture and overall appearance of natural bristles. If the synthetic filament is made to have the equivalent stiffness as a natural bristle the ends of the filaments will not provide the soft feel desired from the brush. Conversely, if the filaments stiffness is reduced to produce a soft feel, the filament will not have the stiffness needed for adequate pick up and deposit of the product.
  • some synthetic bristle brushes (especially those for applying make up such as mascara) has been found to cause irritation to sensitive eyes, as the brushes were not made from bristles of a small enough diameter. Use of small-diameter bristles in cosmetic brushes has also been found to be unacceptable as the bristles pick up too little product and simply “dump” cosmetic product onto the skin.
  • U.S. Pat. No. 5,976,692 to Brezler et al. discloses synthetic monofilaments made from a thermoplastic elastomeric composition containing an aluminum silicate and mechanically crimping the monofilament.
  • a filament comprising a polymer material containing a clay additive wherein said filament is crimped along a length of the filament and has an end that is chemically tipped.
  • a brush having filaments comprising a polymer material containing a clay additive wherein said filament is crimped along a length of the filament and has an end that is chemically tipped.
  • an application package using a crimped, chemically tipped synthetic filament having a mildly abrasive additive such as clay is provided.
  • the application packages are for applying make up such as mascara, nail polish and blush.
  • the filaments used for applying product can be attached to the brush applicator handle by bending the filaments at about their midpoints. Or, the filaments can be attached to the brush applicator handle without bending using the non-tipped end for attachment to the handle.
  • the filaments in the application packages can be attached to the handles by staples, epoxy, heat setting or any other know means for fastening fibers.
  • FIG. 1 a is a schematic view of a chemically tipped wavy filament having a mild abrasive additive.
  • FIG. 1 b is a schematic view of a double end chemically tipped wavy filament having a mild abrasive additive.
  • FIG. 2 is a schematic view of a nail polish brush with chemically tipped wavy filaments having mild abrasive additives.

  • FIG. 6 is a cross-sectional view of the mascara brush package embodiment of the present invention showing the wiper system and the reservoir using the chemically tipped wavy filaments having a mild abrasive additive.
  • FIG. 7 is a cross-sectional view of the nail polish package embodiment of the present invention using the chemically tipped wavy filaments having a mild abrasive additive.
  • the present invention is directed to chemically tipped synthetic monofilaments having a softness, texture and non-uniform wavy appearance for replacement of natural bristles.
  • the present invention differs and is an improvement from what is currently sold on the market as a natural bristle replacement in that it incorporates the combination of: a polymeric material, a mild abrasive additive such as clay, a mild crimp, and a single or double chemically tipped end.
  • the present invention shows improved “pick up” capability of the filament over the currently available synthetic filaments for brushes. (i.e. a filament that does not have clay (textured surface), synthetic, chemically tipped and mild crimp).
  • FIG. 1 a discloses a schematic view of a single end chemically tipped wavy synthetic filament 10 having a mild abrasive additive 30 .
  • FIG. 1 b discloses a schematic view of a double end chemically tipped 60 , 61 wavy synthetic filament 10 having a mild abrasive additive 30 .
  • the synthetic monofilaments or bristles of the present invention are formed from a polymeric material.
  • the polymeric material can be polyesters, nylon, thermoplastic elastomers and polyolefins.
  • the polyesters for use in the present invention include PBT (polybutylene terepthalate) or PET (polyethylene terepthalate) and PET/PBT blends and copolymers.
  • the nylon materials for use in the present invention include nylon 6, 66, 610, 612, and 11 and any blend or copolymers of these.
  • a preferred embodiment of the filament is produced from PBT polyester and contains a mild abrasive to dull the appearance and improve pickup of the filament.
  • the filament also contains a mild crimp to improve appearance in the brush and also improve pickup.
  • the filament is then chemically tipped to produce a very fine tip and provide a very soft feel in the brush.
  • the single or double chemically tipped end 60 , 61 not only provides a desirable soft end but also improves
  • a preferred embodiment of a mild abrasive additive is the use of clay.
  • the filaments of the present invention can be developed with 5% of a hydrous kaolin clay by weight with an average particle size of 1.5 microns.
  • the clay additive 30 creates minute protrusions from the filament that aid in the “pick up” capability of the filament 10 , particularly when used in a brush.
  • the filaments of the present invention when used in a blush brush 80 or 90 enable improved pick up of the blush powder (i.e. point a) for transfer or application to the skin or desired surface (i.e. point b).
  • Other components that can be used in place of the hydrous kaolin clay include calcined kaolin clays, calcium carbonates, aluminum silicates, and aluminum oxides. Particle sizes range from 0.3-5 microns. The range needs to be from 2-10%, and preferably 2-5% by weight to provide enough appearance impact and improve pickup but not create processing issues during extrusion.
  • the brush of the present invention has a stiffness greater than a flexural modulus of 190 ksi.
  • the filaments of the present invention have a flexural modulus equivalent to that of natural bristles. It is preferable that the flexural modulus range from about 400-700 ksi. It is more preferable that the flexural modulus range from about 500-700 ksi.
  • the filament 10 is wavy or crimped using a standard or known crimping process that provides a crimp amplitude 40 .
  • the crimp amplitude 40 occurs at a desired frequency (waves/inch).
  • the wave frequency is shown in FIGS. 1 a & 1 b by the reference number 50 .
  • the wavy filament is defined as having an amplitude of 1-2 mils and a frequency of 4-8 waves per inch.
  • the wavy filament or mildly crimped filament of the present invention can be created using a standard process. Known methods of creating the mild crimp or wavy filament can be used. One such method is described in U.S. Pat. No.
  • the first step includes extruding a monofilament formed of a polymeric material described above containing a clay in relative proportions covered by the ranges described herein.
  • any common polymer extrusion method for monofilaments can be employed and the particular extrusion procedure used in no way limits the methods according to the present invention.
  • extrusion process will also include the usual steps of extruding, quenching, drawing and relaxing the filament rope.
  • the relaxing step includes a conditioning process including heating the monofilament from about 320° F. (165° C.) to about 347° F.
  • the monofilament may be either further post-conditioned or crimped to achieve a non-uniform wavy appearance. Both the post conditioned and crimping process achieve a very natural looking wave in the filament rope and the final brush.
  • the filaments have a base diameter 20 on one end.
  • the base diameter of the filament ranges from about 0.001′′ to 0.010′′ in diameter. This diameter range is preferable for use in cosmetic and other make up brushes.
  • the base diameter does not vary along the length.
  • the chemically tipped portion of the filaments will have a length from 0.04′′-0.4′′ and have a tip diameter less than 0.001′′. While reference is made to a chemically tipped filament, the present invention can be made by any means of tipping such as mechanical tipping that would provide the desired tip diameter of the filament.
  • FIGS. 2-5 shows examples of brush products made using the chemically tipped, crimped synthetic filament containing a mild abrasive additive. These include nail polish brushes, blush brushes and mascara brushes.
  • the present invention in these types of brushes and others improves the ability of the brush filaments to “pick up” material such as nail polish, powder and mascara from a receptacle or reservoir (i.e. point a) and transfer that material to a surface such as a nail, face or eyelash (i.e. point b).
