(UV Protective Finish)
Appearance: Dense beige
Light fastness is the degree to which a dye resists fading due
to light exposure. Different dyes have
diferent degrees of resistance to fading by UV light. All dyes
have some susceptibility to damage due to the incidence of light
particularly the sensitive spectral composition. Light is
energy, and the energy that is absorbed by pigmented compounds
may serve to degrade them or nearby molecules.
UV protective finishing agent LyzerFast TDK consists of UV
absorbers and reflectors. The former can absorb the high-energy
UV rays and convert them to low thermal energy or short-wave
electromagnetic waves. Therefore the absorbers diminish the
hazard of UV rays to humans and fabrics. The reflectors can
enhance the reflecting and scattering powers of fabric against
UV rays. The agent features asepsis, incombustibility,
non-explosion, is safe to the human body as well as incurring no
impact on shade, stength, handling and permeability of fabrics.
The suitable dosage varies between 10
to 25 g/l depending upon the type of color. The finishes to be
applied at the final stage after completing all operations.
Before blending with any other chemicals it is essential to
ascertain the compatability with LyzerFast TDK.
Testing carried out by authoritative organizations prove that
fabric treated with this agent can effectively shield UV
radiation, and provide good protection of UV rays, the damaging
constituency of the UV rays is a shield especially to the UVA
and UVB. These tests in various organizations have shown good UV
protection and light fading is cosiderably reduced
