DICRYLAN® SD deep dye technologies
Unleash the power of the dark side
Delivering unparalleled, never before seen depths of shades on all fibres
DICRYLAN® SD
Has your customer asked you to provide a deeper blue or the blackest black only for you to
be limited by the build-up of the dye or fastness limitations? Have you been frustrated that
those demands cannot be realised without compromise? Well those days are over. Dicrylan SD
represents a technological breakthrough in achieving unparalleled color depths on all fibres
without any compromise on fastness properties.
For the first time increasing requirements and standards can be met without compromise.
Challenges
Limited depth of black and navy shades
Increasing dye add-on can have a negative impact on fastness
Increasing requirement of deeper shades and super-black standards
Difficulty in achieving deeper shades without compromise
DICRYLAN® SD Benefits
Super-black effects on all fibres including polyester, cotton and wool
Achieves darker shades which were previously unattainable
Enhances brilliancy, lustre and surface softness
Reduces dyestuff consumption
Unparalled depth of shade
DICRYLAN® SD cleverly utilizes a novel approach for increasing the depth of shade especially on
dark shades through the use of two mechanisms, light absorption and light polarization.
When light hits the small particles of the DICRYLAN® SD polymer backbone, it scatters in all
directions by particles which are much smaller than the wavelength of the light. This elastic
scattering, known as Rayleigh scattering, results in a deeper shade as less light is reflected back
to the observer.
DICRYLAN® SD Particle
Incident Light
Diffused Light
Absorption
Less reflection resulting
in a deeper shade
Uniquely with DICRYLAN® SD, this effect
is further enhanced by light polarization
resulting from the precise orientation of the
polymer structure.
Polarization is a property of waves that can
oscillate with more than one orientation.
Electromagnetic waves, such as light,
exhibit polarization. When light travels in
free space, in most cases it propagates
as a transverse wave. The polarization is
perpendicular to the wave’s direction of
travel.
With DICRYLAN® SD the polymer units are
orientated not only perpendicular to the light
source but also with each other. This results in a
significant reduction in the light that is transmitted
through providing a further absorption effect
leading to unparalleled, never seen before depths
of shade.
