  • the dye penetrates the fabric in solid form in microscopic dimensions.
  • opening of the polyester pores is ensured by subjecting the same to high temperatures and pressure.
  • the solid dye enters the polyester pores by transitioning to gaseous phase.
  • the pores are closed and the dye is trapped within the pores.
  • thermosol method since washing is not performed after the fabric is dyed, 5-7 tons of water is saved for dyeing 1 tons of fabric.
  • thermosol dyeing method More vivid and darker colors with high fastness are obtained compared to the thermosol dyeing method. In addition, differences do not occur at the beginning- end and wings. In the thermosol method, since the dye does not penetrate the floor completely, superficial color quality problems occur in raised floor dyeing.
  • Efficiency 70% quicker production is made per unit of time, compared to the HT dyeing method. In terms of costs, production is made with approximately 10 times lesser costs compared to the HT dyeing method.
  • thermosol method does not comprise an additional process since no washing is carried out.

  • polyester fabrics are dyed with disperse type dyes which have substantially non-polar, small-molecule structures.
  • the dyeing of polyester fabrics required the use of fiber swelling (phenolic-based) agents. In the present state, this method has been effectively stopped due to the damages done by the contaminating carriers to the environment.

  • the fiber is swollen and it is ensured that the dye penetrates into the fiber.
  • the fiber shrinks to its original crystalline form the dye is trapped within the fiber.
  • polyester By its nature, polyester is not hydrophobic and ionic. It has a compact fiber structure and prevents the passage of chemicals under glass transition temperature (Tg ⁇ 85°C). Above Tg temperature, the structure slowly opens with the increasing temperature at the pores on the surface and inner part. The dimensions of the opening is directly correlated with the increase in the temperature. Even though the dyeing process starts at 104°C, for the efficient diffusion of the dye, the required opening is obtained in the structure immediately above 120°C.
  • the dyes used in the invention are disperse type dyes.
  • the characteristic of these types of dyes are lower molecular weight and higher volatility.
  • the molecular weight of the subject disperse dyes is in the range between 230-350 g/mol.
  • disperse dyes with high sublimation capacity are used.
  • the dyes with higher molecular weight than the disperse dyes are sublimated as well, however, they require higher temperatures due to higher molecular weight and they are less volatile.
