Definitions

  • the present invention concerns a fabric colour guide for monitoring colour of a fabric.
  • fabric colour is extremely valuable to consumers. Indeed, for some garments (e.g. expensive coloured suit shirts, uniforms) precise colour is necessary so that dulling of the colour is perceived as unacceptable. In these cases, reduced colour may even result in the garment being discarded by the consumer. Repeated wash-wear cycles can reduce the colour of a garment.
  • the ability of washing powders to maintain and even rejuvenate colour may be increased by the use of shading dyes .
  • An objective is to provide a device and method for in-home consumer monitoring of the changes in colour of fabric and evaluation of the colour benefits of a laundry composition.
  • the present invention provides a fabric colour guide comprising multiple parts of sheet material, one or more parts bearing at least one colour scale and being pivotable with respect to at least an adjacent part and each pivotable part selectable for comparison with fabric of a colour corresponding with said colour scales/s by pivoting of the pivotable part(s) .
  • the pivotable parts preferably bear a colour luminance scale comprising a colour/range of colours varying progressively from low (pale) colour at one end of the scale to high (deep) colour at the other end of the scale.
  • L*a*b* values the CIE LAB colour space, (CIE 1976 L* a* b*)
  • L* is the lightness value of the colour
  • a* is the red-green value (negative values indicate green while positive values indicate red)
  • b* is the yellow-blue value (negative values indicate blue and positive values indicate yellow.
  • the highest colour may be defined as L * max , a * max , b* max (UV- included) such that:
  • L * max is in the range 1-70, preferably 5-50 a * max is in the range -40 to +40, preferably -20.0 to + 20.0 b* max is in the range +40 to -40, preferably +20.0 to -20.0. and the minimum colour values as L * min , a * min , b* min such that
  • ⁇ L L min - L max , where ⁇ L* is 3 to 30 units preferably 5 to 10 units, reflecting the luminance of the coloured cloth
  • L * max is in the range 1-30, preferably 5-15 a * max is in the range -8 to +8, preferably -4.0 to + 4.0 b* max is in the range +10 to -15, preferably 0 to -10. ⁇ L* is preferably 3 to 30 units preferably 5 to 10 units. Intervening colour values in any scale or in any part of a scale may be between the above extremes. The intervening colour values may be equally distributed.
  • the L* values are varied and the a* values and b * values maintained constant or at least to within +/- 1 unit.
  • the a* may be maintained at zero or at least close to zero (within +/- 1.0 and preferably within +/- 0.3 of zero) .
  • the b* values may be maintained constant at a value (to within +/- 1 unit) which is less than 2 and preferably less than +/-3 units.
  • the colour luminance scale is preferably stepped, comprising a plurality of discrete portions, wherein the transition from one portion of the scale to another portion, involves a step-change in colour and/or lightness.
  • the total colour difference between adjacent shades is preferably such that the shade of one portion of the scale is distinguishable by the naked eye from the shade of an adjacent portion. This affords in-home testing by the consumer, without the need for laboratory conditions or equipment. However, at the same time it is preferred that the scale is focussed on subtle changes in colour within a restricted range of high colour values.
  • the difference in colour between adjacent portions may be defined such that the colour of each portion - A -
  • the total colour difference represented as the ⁇ E value corresponding to the Ln (normally calculated from the positive square root of [ (L * n - L * n _i) 2 + (a * n - a * n -i) 2 + (b * n ⁇ b * n -i) 2 ] but in this case there is no change in a* or b*) is preferably greater than or equal to 0.5, and more preferably 0.5 to 2.0, (UV-included) .
  • the portions preferably have a uniform shade of colour.
  • a uniformly shaded portion is easier for the consumer to match with the fabric.
  • the guide may be labelled with directional visual indicia to direct the user to hold the product in a predetermined orientation.
  • the higher colour values may be on one side i.e., the right or left of the user (when facing the product) .
  • the portions of the scale or palette may be labelled with numbers, names, logos etc. applied by e.g. printing to ease monitoring .
  • the portions of the scale may be arranged in a single row. Alternatively, the portions may be arranged in multiple rows. The row or rows may be straight or curved.
  • the portions are of equal size and shape. This is advantageous in that no portion/s is/are given undue preference due to size. This affords more accurate comparison between the colour of the portions and the fabric based on colour.
  • the pivotable parts may pivot (via e.g. a pivot eyelet) about an axis generally orthogonal to the plane of the sheet material.
  • the guide may comprise a fan configuration, whereby discreet, pivotable parts can be fanned out to select an appropriately coloured part.
  • one or more pivotable parts may pivot about an axis lying within the plane of the sheet material, in the manner of a hinge.
  • pivoting may be achieved by folding a single piece of sheet material to provide multiple parts, whereby the folding line or lines provide a hinge, e.g. a living hinge, about which parts may pivot.
  • a hinge e.g. a living hinge
  • Separate pieces of sheet material may be joined by hinge elements to provide a similar arrangement.
  • the resulting guide may comprise a concertina arrangement. Alternatively, it may comprise a series of nested folds.
  • the parts may bear sand colour scales on both (opposite) sides of the sheet material (ie. it may be double-sided) .
  • Scales on opposing sides may be complimentary. For example by appropriate L* levels, one side may bear a scale of greying of the colour (a ⁇ L* with values at the low end of the L* scale - or increased black) ; the opposite side may bear a scale of whitening ( ⁇ L* with values at the high end of the L* scale - high luminance) .
  • Each colour scale may have 2-20 portions, preferably 2-10 portions.
  • a more complicated guide offers greater accuracy however excessively complicated guides can be off-putting for some consumers.
  • a very simple guide increases the frequency of use of the device for first time users, and monitoring becomes more habitual.
  • There may be a choice of scales a first scale having 3-20 portions and at least one other scale having a lower number, such as half, than the first scale.
  • the guide may have 3.5. This is advantageous for colour guides focussed on a restricted range of colour, as described above. This is the optimum range which provides portions which are easily visually distinguished by the consumer .
  • sheet material it is meant less that 3 mm thick, preferably less than 2 mm more preferably less than 1 mm. This has the advantage that the surface carrying the scale is not distanced (by thickness) from the fabric substrate during measuring, which allows for more accurate comparisons .
  • the guide is sufficiently flexible so it can flex to lie against a flexible substrate such as fabric. This has the advantage that the guide can be easily flexed to conform to the shape of a garment to carry out accurate colour comparison .
  • the colour guide may be provided with packaging, in which the associated detergent composition is contained.
  • the guide may be attached and inside. This has the advantage that the guide is quickly obtained on opening the package.
  • the colour guide may be wrapped in packaging to protect it from the washing composition, so that when it is initially retrieved from the pack and used, it is not contaminated with the washing composition which could then transfer on to the fabric during colour measuring.
  • the guide may be releasably attached to the packaging, preferably externally of the packaging. This prevents the guide being accidentally lost and also the consumer's attention is drawn to the guide.
  • One or more parts may be pivotable whilst the guide is attached to the packaging exterior. Removal of the guide from the packaging may involve pivoting one or more pivotable parts. Removal of the guide may involve a progressive unfolding and removal by pivoting of the pivotable parts.
  • the invention provides a method of consumer-measurement of the colour of a fabric, the method including the step of comparing the fabric with a selected pivotable part of a colour guide of the first aspect of the invention including any optional, advantageous features as described above. Parts may be pivoted to select a particular part appropriate for the intended comparison, and/or pivoted to enable positioning of the part adjacent the fabric to carry out the comparison.
  • the step of comparing may take place after washing with a laundry composition. Alternatively or additionally, it may also take place before washing. This allows the consumer to evaluate the efficacy of the washing process to improve colour.
  • the step of comparing may be repeated e.g. before and/or after multiple e.g. consecutive washing operations, for evaluation of the progressive improvement in colour of a particular washing composition.
  • the guide can confirm the maintenance of colour due to a particular washing composition.
  • the invention also allows the consumer to compare the different washing compositions or brands of compositions or other conditions such as temperature of the wash.
  • the step of comparing may take place after other events which affect washing, for instance drying of washed fabrics outside, in sunlight etc.
  • the invention provides a package containing a laundry composition in combination with a fabric colour guide of the first aspect, including any optional advantageous features as described above, and preferably together with instructions for use of said fabric colour guide to measure the colour of a fabric according to the method of the second aspect including any optional, advantageous features as described above.
