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.
- washing powders to maintain and even rejuvenate colour may be increased by the use of shading dyes.
- efficacy of such washing powders is often difficult for the consumer to evaluate as any analysis relies on consumer memory of the colour of a garment prior to washing.
- An objective is to provide a highly accurate 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 measurement system comprising at least one pair of corresponding colour guides, the or each pair comprising a first colour guide to be washed and a second colour guide to be dry-stored, wherein the guides comprise corresponding coloured fabric.
- the invention allows the consumer to compare the washing/conditioning compositions of different brands or variants or to compare washing conditions.
- the monitoring is effected simply by adding the first colour guide to a laundry load, whilst storing the second colour guide and then comparing the two guides after the wash has completed.
- the invention provides a method of consumer measurement of fabric colour change due to a washing operation, the method using a fabric colour guide of the first aspect (including any optional/preferred features as set out herein) and including the steps of:
- dry storing and “dry-stored” as used herein, means storing in any suitable place but not washing or wetting.
- the invention provides a package containing a laundry composition in combination with a fabric colour measurement of the first aspect of the invention (including any optional/preferred features as set out herein) and preferably together with instructions for use of said fabric colour measurement system according to the method of the second aspect (including any optional/ preferred features as set out herein) .
- a colour guide together with the washing powder enables the consumer to effectively monitor the effectiveness of the powder and appreciate the benefit of colour agents added to the washing powder. Thus the consumer is given more control over the evaluation of different products and different washing and also drying conditions .
- the step of comparing may take place after other events which affect washing, for instance drying of washed fabrics in a tumble dryer, outside, in sunlight or in shade.
- the step of comparing may take place after washing the first colour guide with a laundry composition.
- the system comprises a plurality of first colour guides, and the method involves the step of using a fresh first colour guide for each washing operation.
- a fresh guide is useful in the event colour damage occurs but consumers wish to monitor the colour changes on multiple occasions .
- both guides have (before use) substantially common colours and preferably texture and further preferably the guides have (before use) identical colour and/or texture .
- both guides are of a common material, and/or shape and/or size for ease of comparison. Most preferably the guides are (before use) identically visually.
- first and second guides of one pair comprise identical fabrics.
- the fabric preferably comprises a fibre based on cellulosics, polyester, nylon elastane, acrylic, cotton. Most preferably it comprises cellulosic cotton and polyester .
- the fabric has a woven construction.
- Woven fabrics are classified as to weave or structure according to the manner in which warp and weft cross each other.
- the three fundamental weaves, of which others are variations, are the plain, twill, and satin. Further preferably the weave is plain and/or twill (as is used for denim fabrics) .
- the fabric is preferably washable preferably can withstand temperatures of the wash up to 90 degrees and drying temperature up to 150 degrees.
- the or each guide is shaped and/or sized to be visually distinct from remaining laundry items, so it can be easily picked out from the laundry load after washing. Accordingly it may be substantially smaller or may be a visually distinct shape. Visually interesting shapes such as those defined by a perimeter of undulating curves distinguish the guide from remaining laundry items.
- the preferred size of the or each guide is less than 15cm (height and/or width) and further preferably less than 10cm (height and/or width) .
- the guides may be shaped to visually distinct from remaining laundry items; so the first guide can be easily picked out from the laundry load after washing and to enable easy dry- storage of the second guide. Accordingly they may be shaped to resemble iconic articles of clothing such as the T-shirt or a pair of jeans etc., but very small size.
- the waist line should be less than 15 cm and further preferably less than 10 cm, any may be even less than 5 cm.
- At least the first colour guide comprises one or more apertures.
- Such aperture or apertures may be defined by a strip of the guide so as to create a hook or loop. This offers the advantage of enabling the guide to be attached to a larger article which aids locating the guide at the end of the washing process.
- the second colour guide may comprise a hook for ease of dry storage.
- the guide may comprise a single colour.
- the guide may comprise a colour palette of different colours.
- the colours may be grouped according to hue, lightness, position in the spectrum or they may be in random order.
- the guide may comprise a colour scale which displays a colour/range of colours varying progressively from low colour at one end of the scale to high colour at the other end of the scale.
- L*a*b* values the CIE LAB colour space, (CIE 1976 L* a* b*)
- the colours within any range may be according to a change in 10 colouration (a* and/or b*) and/or change in luminance/lightness (L *) .
- the highest colour may be defined as L * max , a * max , b* max (UV- included) such that: 15
- 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 20 where ⁇ L* is 3 to 30 units preferably 5 to 10 units, reflecting the luminance of the coloured cloth
- ⁇ b* is +/- (0 to 30) units, preferably +/- (0 to 10) units reflecting the blue/yellow value of the colour of the cloth.
- the a* values may be constant or at least within +/- 1 unit, to restrict the guide to focus on blue-yellow colouration rather than red-green.
- the b* values may be constant or at least within +/- 1 unit, to restrict the guide to focus on red-green colouration rather than blue-yellow.
- the L* valves may be constant or at least within +/-1 unit to restrict the guide to focus on red-green and/or blue-yellow i.e. colour proper rather than on lightness or luminance .
- 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.
- ⁇ a* is preferably +/- (0 to 10) units, preferably +/- (0 to 5) units.
- ⁇ b* is preferably +/-(0 to 30) units preferably +/- (0 to 10) .
- Intervening colour values in any scale/palette or in any part of a scale/palette may be between the above extremes. The intervening colour values may be equally distributed. Alternatively, the L* and b* and a* values may be lowered in alternate steps.
- the colour palette or scale may be continuous (where colour changes gradually) across the guide or scale it may be stepped. In the case of a stepped scale, this will comprise a plurality of discrete portions, wherein the progression from one portion of the scale to another portion, involves a step-change in colour and/or lightness.
- the portions may be separate pieces of fabric, which are attached e.g. by stitching or fabric glue.
- the difference in colour between adjacent portions may be defined such that the colour of each portion has Lab values: L * n , a * n , b * n , defined by:
- the total colour difference represented as the ⁇ E value (corresponding to the positive square root of [ (L * n - L * n -i) 2 + (a * n - a * n -i) 2 + (b * n - b * n -i) 2 ] is preferably greater than or equal to 0.5, and more preferably 0.5 to 2.0, (UV- included) .
- L* and b* may vary alternately on the scale, such L* only changes when n is an even number and b* when n is an odd number.
- L* and b* may vary alternately on the scale, such b* only changes when n is an even number and L* when n is an odd number.
- the L* value may decrease linearly whereas the b* values decrease for even values of n.
- the b* value may decrease linearly with each value of n, whereas the L* values are only decreased for even values of n .
- L* and a* may vary alternately on the scale, such L* only changes when n is an even number and a* when n is an odd number.
- L* and a* may vary alternately on the scale, such a* only changes when n is an even number and L* when n is an odd number.
- the L* value may decrease linearly whereas the b* values decrease for even values of n.
- the a* value may decrease linearly with each value of n, whereas the L* values are only decreased for even values of n .
- the portions may have a uniform shade of colour.
- a uniformly shaded portion is easier for the consumer to match with the fabric.
- continuous it is meant that the change in colour appears (to the naked eye) continuous along the scale or scales.
- a continuous scale (s) may however, include demarcation by visual indicia e.g. lines, so as to divide up the scale into multiple portions.
- the guide may be labelled with directional visual indicia to direct the user to hold the product in a predetermined orientation.
- 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 or palette may be arranged in a single, straight row. Alternatively, the portions may be arranged in multiple rows. The row or rows may be straight or curved.
- the guide may include a planar section or sections.
- planar it is meant less that 10mm thick, preferably less than 6 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 may be constructed with a 3-dimensional section or sections. This can aid retrieval after the washing process has been completed.
- the 3-dimensional section/s may be formed by an arrangement of sections or panels attached e.g. by stitching.
- the sections/panels may vary in colour, wherein such colour variations is as described herein.
- 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 the colour comparison .
- the colour guide may be provided with the packaging, unattached and loose inside. This has the advantage that the guide is quickly obtained on opening the package.
- the or each 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 as this could interfere with colour measuring.
- the guide may be perfumed, and the perfume of the guide may be the same as or correspond with the perfume of the laundry composition .
- the detergent powder may contain an agent for improving rejuvenating or maintaining colour.
- the agent may comprise one or more dyes for increasing perceived colour.
