What Is Thermomigration?

• Thermo migration is the movement of disperse dye
  from fibre / fabric into the spin-finish or
  finishing chemical used in processing , during
• heat treatment storage period
• Heat setting promotes dye migration from the
  fiber interior to the fiber surface, leading to
  lower wash fastness. This phenomenon is known as
  thermo migration which is the diffusion of dye as
  a result of the breakage of the interaction
  between dye and fiber by the increased thermal
  motion of both the dye molecule and the polymer
  chain at elevated temperatures.

Market Trend

• Polyester and its blends have been widely used
  for sportswear and leisurewear which need to have
  high level of wash fastness to endure frequent
  washing.
• Recently there is a worldwide growth in the micro
  denier polyester because of the soft hand and
  comfort.

5
Factors Influencing Thermomigration

• As the diameter of the fiber becomes smaller, the
  total surface area of the fiber increases
  considerably. A greater amount of dye is needed
  for the micro denier polyester to reach the same
  depth of shade as the conventional polyester.
  These often result in deteriorating wash fastness
  of the micro denier polyester. Thus thermo
  migration becomes more severe as the denier of
  fiber is smaller, and it is regarded as the
  origin of low wash fastness of the micro denier
  polyester.
• The fiber thickness.
• The chemical structure of the disperse dye.
• the amount of absorbed dye in the fiber.
• heat setting conditions. Thermo-migration in
  stenter is promoted between 140- 1800C .
• Thermo migration is triggered with nonionic
  ethylene oxide surfactants available in
  spin-finish chemicals applied on dyed fibers
  during yarn manufacturing or in silicone
  softeners in stenter padders.

Why Powersil-NT-PES

• Wash fastness of dyed polyester fabric is closely
  related to the degree of thermo-migration of
  disperse dye during heat setting.
• It is an innovative special silicone emulsion
  which in contrast to classic formulations does
  not enhance the thermo-migration of dispersed
  dyes on polyester fabric.
• Due to a sophisticated formulation
  thermo-migration and bleeding is reduced, wash
  fastness properties are improved the colour
  depth is enhanced.
• Suitable for Poly/Viscose, Poly/Wool polyester
  fabrics.
• Excellent elastic resilience, soft and smooth
  handle.
• It is exhaustible silicone with cationic
  character
