In-vitro consumer-relevant dingy test fabrics models. Spectroscopically characterised for fluorescence determinations

Selection of white commercial fabrics, as a monitor substrate, that contains fluorescent whitening agents from textile mills. Ready to experiment in the field of collisional fluorescence quenching

Ample set of clean, soiled and stained dingy test fabrics according to more than ten (10) regional laundry markets, including India (two versions), China (two versions), Europe, Latin America, North Africa. Stained areas include market relevant adjacent dingy fabrics

Coloured commercial fabrics with adjacent white commercial fabrics, previously treated to become dingy white and dingy coloured test fabrics, that represent actual visual context scenarios about colour contrast effects

Their specific intended use is to represent dingy, soiled or stained commercial white and white-coloured garments that world's consumer use to evaluate laundry results, in the fields of cleanliness, whiteness, olfactive-cleanliness, and colour-care

For the first time in the industry, they provide a relevant visual and olfactive context to understand sensory perceptions. It has opened the door to new instrumental analysis approaches as well as to novel alternatives to conduct sensory analysis not only at lab facilities but also with consumers under real visual scenarios

All dingy fabrics are spectrofluorimetrically characterised and ready to conduct virtual experimentation using CLLS' algorithms collection, with the purpose to experiment with world's consumer response using a large matrix of laundry scenarios.

A special case:

The Collar and Cuffs Stained Monitor

Code: DINGY_TN/CP/

Specified intended use: to represent commercial stained worn (stained dingy) white garment collars, in which world´s consumers evaluate cleanliness in the collar context, by remotion of the specific stained area after first household washing/drying processes

One (1) monitor contains one (1) double-layered fabric swatch with two (2) areas: collar and cuff stained area immersed in a dingy substrate that surrounds it

Consumer cleanliness assessment of laundry product is not the same around the world, but it has been found that some washing problems are nearly the same despite different cultures and habits. Consistently, remotion of easily perceived stains present on white collar and cuffs constitute one of the icons linked to final consumer value delivered by laundry products.

Unfortunately this simple cleanliness perception fact from the consumer point of view, is a very complex process from the R&D perspective, not only due to the complexity of the inorganic and organic constituents of the stain, but also due to the interaction of different fabric surroundings (the area in direct contact with the skin and the rest of the collar area) on final consumer cleanliness perception. CONSUMERTEC, using a custom-built non-contact mini spectrofluorimeter, has characterised the absolute spectrometric properties of very small fabric areas (less than 6 mm2), like the strip-shaped remanent collar and cuffs stained area after some process of wash, and its fabric surrounding, as well as accurate determination of typical fluorescence spectroscopy properties like: quantum absorptance function, quantum yield, and total, reflected and luminescent radiation coming from the fabric and capable to reach consumer's eyes.

Our approach, a special constructed double-layered test fabric with different dingy surroundings that simulate a worn white collar, with one area of fresh stain that mimic the combination of body and ambient soil, specifically a mixture of components of four groups: sweat gland secretions, sebaceous gland secretions, dead skin cells, and ambient particle and dust. The final monitor is obtained after a total of ten (10) washes and one (1) complex staining step. Surrounding dingy fabrics can follow different standard market realities (India, China, Latin America, Europe, USA or others) or customised specific realities according to client needs.

This standardised monitor is prepared on double-layered woven poly/cotton 65:35, clean dingy version. Each monitor of 10 cm X 10 cm.

Another very complex case:

The Armpit Stained Monitor

Code: DINGY_TN/AX/

Specified intended use: to represent commercial stained worn (stained dingy) white garment armpit area, in which world´s consumers evaluate cleanliness in that area context, by remotion of the specific stained area after first household washing/drying processes

One (1) monitor contains one (1) fabric swatch with two (2) areas: armpit stained area immersed in a dingy substrate that surrounds it

Probably is the second more problematic and common body stain in the consumer market and from the consumer point of view, a truly headache for the person in charge of laundry. From a technical point of view this is really complex stain that results from the interaction of deodorant product ingredients with underarm human secretions and proteinaceous residues, under oxidative conditions at certain temperatures, in a continuous cycles of wearing and washing.

Our approach has been to model and simulate consumer realities in order to obtain a standardised stain with relevancy to different market scenarios.The visible stain is generated after three (3) cycles of staining and washing, onto a clean dingy fabric. The final monitor is obtained after a total of thirteen (13) washes. Relevancy depends on different commercial deodorants present in the market, and different surrounding fabric's dingy conditions, which in turn can follow different standard market realities (India, China, Latin America, Europe, USA or others) or customised specific realities according to client needs.

This standardised monitor is prepared on knitted cotton 100% or woven poly/cotton 65:35, clean dingy versions. Each monitor of 11 cm X 12 cm.

Selling unit: per package of thirty three (33) units

Example: Commercial machine washing process, following some specific Asian conditions, gentle cycle


A unique way to measure consistently olfactive cleanliness under a consumer relevant olfactive context:

The Standardised Fatty-like Persistent Malodorous Monitor

Code: DINGY_MS/

Specified intended use: to represent commercial worn (clean dingy) white garment with persistent fatty-like malodorous, that world´s consumers use to evaluate olfactive cleanliness, by masking residual malodorous after first or consecutive household washing/drying processes

One (1) monitor contains one (1) fabric swatch with a homogeneously yellowish cast.

Deposition and redeposition of body soils during continuous cycles of wearing-washing-drying-wearing, accumulate organic fatty-like residues on fabrics, mainly synthetics, capable to be oxidised by temperature and natural UV radiation; this reality generates peculiar malodorous easy to notice as characteristic of long-life used garments. This condition is well noticed in bed-sheets and underwear, usually poly/cotton mixtures, which is nearly not-removed by normal laundry processes. CONSUMERTEC has reproduced these conditions in a standardised way, creating a test fabric to act as a consumer relevant context for olfactive cleanliness perception studies.

It is expected that contains a complex odour profile characterised by: aldehydes, organic acids, ketones and esters with fatty smell notes from lipids oxidation, strongly fixed to synthetic fibres. This monitor, in use by CONSUMERTEC during the last decade, has been a unique and valuable tool to differentiate fragrance technologies present or capable to be present in the laundry market, in consumer relevant terms.

This standardised monitor is prepared on knitted poly/cotton 65:35. Each monitor of 15 cm X 15 cm.

Example:


Colour-care perception that includes local contrast effects:

The Coloured and Dingy White Monitor

Code: DINGY_CC/

Specified intended use: to represent commercial worn (clean dingy) coloured garment that combines white and colour areas, in which world's consumers evaluate colour-care benefits of laundry products after consecutive household washing/drying processes

One (1) monitor contains six (6) fabric swatches, four (4) coloured, one (1) original white and one (1) clean dingy white

Current trend in the garment industry is the combination of colours and whites strips. One colour cloth is now the exception. This textile trend is a real challenge from the colour-care perspective, because now the problem is not only to preserve colours but also to preserve the whites areas, because if both are part of the visual scenario, there is full interaction between them. Detrimental changes in the whites areas will affect significantly the colour-care perception due to local contrast effects, colour will be perceived dull. This new dingy monitor from CONSUMERTEC offers for the first time a practical standardised alternative to technology innovators to experiment in the field of colour care in consumer relevant terms.

Contrast effects or chromatic induction are very well know phenomenology in vision science but not implemented in the detergency industry, due to the regular use of basic colorimetric procedures. Algorithms to compute this visual effect needs a more complex approach. CLLS collection of algorithms coded by CONSUMERTEC offers this capability grounded on very recent advances in numerical models to represent more realistic interaction between white and colour in the same surface visual scenario.

The monitor contains four (4) coloured swatches which are new original fabrics, commercial or standardised (AISE standards). Additionally it contains one (1) white swatch which is a new original fabric and another one (1) which is a clean dingy swatch, DINGY_CL, prepared according to relevant consumer realities, i.e. it represents a clean dingy white garment after ten (10) cycles of washing/drying cycles following different standard market realities (India, China, Latin America, Europe, USA or others) or customised specific realities according to client needs.

This standardised monitor is prepared on cotton 100%. Each monitor of 22 cm X 40 cm.

Selling unit: per package of twenty five (25) units

Minimum order: one (1) package of twenty five (25) units

Regular price: US$ 20.5o / unit

Ready to experiment with CLLS collection of algorithms, to predict sensory responses from different types of consumers at relevant different visual scenarios, and to link that responses to actual radiance coming from fabrics at those scenarios, which is the radiant flux that potentially can reach eye’s retina.

In-vitro Models

The "clean" fabric worn by consumers is not clean, it is a dingy fabric. After the first cycles of wearing/washing/drying/wearing, some level of body and ambient soil redeposition occurs as well as white fabrics become yellowish due to a light induced loss of fluorescence, and finally become tinted by deposition of dyes coming from others garments and more importantly by deposition of dyes present in laundry product to improve visual perception. Therefore white clean garments in the market are really clean dingy garments, not-new-garments ready to wear, not ready to wash.

CONSUMERTEC has designed a group of test fabrics to represent this complex reality relevant to the worldwide laundry market. Laundry markets that we represent are: India (two versions), China (two versions), South east Asia, Australia/New Zealand, Japan, Western Europe, Russia, Balkans, Middle East/North Africa, Latin America, USA/Canada, Africa Sub-Saharan. Each laundry market has been characterised by: environmental particle matter, land clays and dust, natural sun radiation during drying/wearing, washing conditions and laundry products. The general code of these group of clean dingy monitors are Dingy_CL.

In real market conditions, clean dingy garments become soiled or stained during consumer wearing:

  • worn garments are considered soiled by consumers if a general appearance is different to the original clean status, usually a yellowish or greyish cast is easily detected visually in most of garment surface which is corroborated by smell evaluations and crease presence. The general code of these group of soiled dingy monitors are Dingy_SD
  • beside that, worn garments are considered stained when an extraneous material-coloured area is easily detected visually; some garment areas typically checked looking for stains are among others: knees areas, front areas, collar and cuffs, armpits, and pants bottom areas. The general code of these group of stained dingy monitors are Dingy_TN

Continuous redeposition of body soils, including fatty materials present on dingy fabrics, become a source of unpleasant smells in used garments, not removed during washing cycles, but masked by some laundry products and not by others. Consumers easily detect this peculiar rancid-like smell on worn fabrics which is characteristic of long life garments. The general code of these group of malodorous dingy monitors are Dingy_MS




Frequently Asked Questions (FAQs)

Why use in-vitro models?
... because consumer relevancy really matters

Consumer understanding means experimentation. The challenge for innovation teams is to understand how different consumer segments around the world perceive benefits during the complex interaction with brand and products under a myriad of scenarios. The only reliable way is to characterise market realities piece by piece, one in a time. In-vitro models are one of those pieces.

Using in-vitro dingy test fabrics models, for whiteness, cleanliness, olfactive cleanliness or colour-care understanding, marketing teams will be more confident in using fabric monitors which appear similar to the real ones. R&D teams use in-vitro models to include market realities in the lab, and have the opportunity to conduct experiments to understand the influence of several variables, including different technologies and formulas, on final performance from the point of view of the market.

CONSUMERTEC dingy fabrics are part of the experimental work at detergency labs as well as part of marketing activities to collect consumer responses from visual sensory analysis at home level under real visual scenarios.




Why CONSUMERTEC test monitors are spectroscopically characterised for fluorescence measurements?
... because innovation teams needs to predict consumer response under real market conditions

Most of CONSUMERTEC monitors are produced from commercial white fabrics, which means fabrics with high levels of fluorescent agents. That simply fact changes everything in fabric subsequent reflected and emitted radiant energy capable to reach consumer eyes. Extraneous material on them generate complex collisional fluorescence quenching process, that changes significantly fluorescence emission profiles and quantum absorption functions. For that reason, in order to predict further changes on fabric reflectance and emission under illuminant with different UV relative content, it is mandatory to precisely characterise the fluorescence properties of dingy fabrics, which become fabric fingerprints, and the starting point to generate predictive spectral properties.




Why is so influential the presence of pigments on wetted or dry washed fabrics?

For many years the laundry industry introduced coloured pigments on bar, powder and liquid detergents only due to aesthetics reasons, and the favourable consumer acceptance was interpreted as a matter of product hedonics. However in the last decade, new understandings about visual perception, specifically the importance of lightness and colour contrast, have helped to move our attention on the positive influence that pigments would have on cleanliness and whiteness perception. Now this field is part of the brand and product design efforts.

Low levels of shading dyes with a greenish, bluish or reddish cast, combined with the greyish and yellowish shade due to soils redeposition and loss of fluorescence (after several cycles of washing and drying), configure the specific fabric surrounding area for the remanent stained area after some washing process. Final consumer cleanliness-enough perception will rest on final comparison of those two areas; by this way pigments design affect cleanliness perception, and that will be more or less critical depending on fabric-pigment affinity.

Whites are not the perfect white (100% reflectance of incident radiation on the visible spectrum). Commercial white fabrics on the garment markets contain high levels of fluorescent agents and are well pigmented, mainly with a bluish, greenish or reddish cast. On the consumer side, the acceptable and preferred level of whiteness is strong affected by previous perception during years as well as local conditions like white fabrics on the market and also by leading pigmented washing products. Finally, what consumer segments consider as enough and acceptable level of whiteness on critical garments after 10, 30 or more than 50 washes (as happens with white school uniforms), has to be locally characterised and understood, and well planned as part of the consumer value proposal which is designed by innovation teams.

Last but not least, it is now well understood that during soaking stages, the visual perception of wetted pigmented white fabrics, i.e. the level of change detected in comparison with the dirty condition, has a definite influence on the final consumer cleanliness and whiteness benefit perception, which is a good example of a priming effect; in other words the product has to show that performs fine from the beginning! Therefore, visual perceptions of pigmented wetted fabrics at the soaking stage (when exists) has also be designed.
