Test Fabrics
Detergency studies only focused on technology assessment
use standardised stained test fabrics with unreal level of
stains applied onto unreal substrates, final results help to
discriminate technologies and detergent ingredient
concentrations, but have no correlation with consumer
realities. DETERTEC approach on test fabrics is to offer
relevant level of soils and stains on relevant substrates so
as to mimic as close as possible, actual washing results
that consumer evaluate visually after some washing/drying
process.
DINGY-CL.
Test fabric with redeposited body and ambient soils, and
light-induced yellowished. A clean dingy fabrics, that
represent not-new-garments ready to wear (not ready to
wash). Yellowish, reddish, greenish, bluish or greyish
shaded fabric according to specific market realities.
DINGY-SD.
Soiled dingy test fabric with fresh body and ambient soils.
A uniformly soiled dingy test fabrics that represent a
soiled-worn-garments ready to wash but not stained.
Yellowish or greyish cast is applied onto a shaded dingy
fabric DINGY-CL.
DINGY-TN.
Stained dingy test fabric with relevant coloured stains. A
soiled dingy test fabric with localised stained areas that
represents stained-worn-garments ready to wash. Several
relevant stains are applied manually at real concentrations
levels onto a soiled dingy fabrics DINGY-SD.
A special case:
the collar and
cuffs stain.
DETERTEC's approach to develop these relevant models of
fabrics has been not only an extensive research on chemical
constituents, physical characteristics and levels of
concentration of soil and stains on fabrics, but also, and
primarily, an extensive characterisations of advanced
spectral properties of real new, dingy and stained fabrics
from the real consumer market using a custom-built
spectrofluorimeter specially designed for this purpose.

Outsourcing
Laboratory
We offer private outsourced laboratory studies to
evaluate different aspects involved in product, garment or
washing process performance, both in first and repeated
washes. Our research strategies use standardised and
innovative methods, taking into account actual laundering
conditions and relies on a broad statistical base during its
design, execution and data analysis. Studies include, among
others:
hand-washing (with or without soaking,
dispersive or non-dispersive scrubbing, scrubbing by hand or
by brush), machine washing (top or horizontal loaders) or
combined procedures;
the use of bars (soaps, synthetics or combinations),
powder, liquid, tablets, or paste detergents;
indoor or out-door drying (direct or diffuse full
controlled natural sun radiation)
Final evaluations are based on instrumental data and/or
sensorial responses provided by consumers and/or trained
panels, taking as a point of reference consumer's actual
evaluation criteria as well as the visual laundry scenarios
in which evaluations occur. Special attention has been put
to conduct instrumental evaluation of washing results with
relevance to visual assessment by consumer's eyes.

Spectroscopy
Technologies
Based on recent developments on photonics and thin film
technologies as well as on in-house data processing scripts
using JMP software, DETERTEC has integrated several hardware
and software components from different suppliers focused to
conduct spectrometric measurements as close as possible to
real energy interaction found in the market. Absolute
spectrometric measurements are rested on in-house
calibration procedures traceable to international standards.
Laundry
visual scenarios characterisation. Simultaneous absolute
spectroradiometry at washing environments. Full
characterisation of natural and artificial source of
illuminations at critical moments when consumer conduct
visual evaluations before, during and after laundry, as well
as scenario luminance measurement at eye's level.
Soiled, stained and washed
fabric characterisation. Non contact spectrofluorimetry
of dried fabrics before and after the washes. Absolute
radiation measurement coming from dried fabrics capable to
reach consumer eye's. It include measurements of actual
soiled fabrics like collar and cuffs areas before and after
the wash.
Consumer visual
experiences during washing. Non contact
spectrofluorimetry of wet stained/soiled dingy fabrics in
the washing liquor. The fabric is immersed in the washing
liquor and the sensor is place in or out the washing liquor.
Focused to understand consumer visual experiences during the
laundry, mainly when consumers conduct visual assessments at
the beginning or at the end of the soaking process, in hand
washing markets. For some market realities, that consumer
perception is linked to final consumer value.
Natural sun radiometry
and transmittance properties. Absolute
spectroradiometry of natural ultraviolet and visible
radiation, and 'in vitro' evaluations of sun-protection
technologies. Measurements of direct, diffuse and global sun
irradiance in the range of 280nm to 800nm. Calculation of
sun and ultraviolet protection factors.

Computer-based
Technologies
Rapid changes in computational capabilities at affordable
prices are offering new alternatives to 'in silico' R&D
activities. Materials, consumers and their interactions are
now capable to be virtualised, specially, thanks to recent
mathematical models of consumer perceptions. DETERTEC has
built innovative systems based on the powerful scripting and
graphical capabilities of JMP software.
Modelling
consumer's cleanliness and whiteness perceptions. An
analytic and geometric modelling procedures to develop
customised stain removal indexes and whiteness formulas that
correlates with consumer perceptual quantities. An
analytical model approach, in the sense that we start to
model defining general mathematical expressions, which are
functions of colour attributes perceptions like: lightness,
red-green opponency and blue-yellow opponency. Geometric
modelling systems are also applied, thanks to recent
development on interactive 3D graphic capabilities. Using a
geometric modelling approach in combination with analytical
models, it is possible to shape quadric functions like:
two-sheets elliptic hyperboloids and ellipsoids, to reach
levels of correlation or more than 95% with consumer
responses.
LaundryVisualSim.
A novel mesoscale modelling and simulation system of
consumer visual assessment of washing results at relevant
visual scenarios. Consumer-focused detergency virtual
R&D. An 'in silico' approach applied to laundry products
R&D, that simulates fabrics spectroscopy changes during
one or multiple washing process, and predict different
consumer cleanliness and whiteness perception responses when
evaluating washing results under a multitude of laundry
scenarios. Strong flexibility is the key component to keep
relevancy in a worldwide base. An incredible powerful tool
to conduct virtual R&D focused to increase efficiency
and productivity of our clients, with tremendous savings
in time and money.
