Product Description

  • Polyester whitening agent(red light)
  • 【Product Features】
    • Strong fluorescence, high whiteness, and good washing fastness

 

 

  • 【Product Application】
    • Mainly applicable to the whitening and brightening of polyester fibers and their blended fabrics, especially suitable for low-temperature (95 - 100°C) whitening of polyester fiber knitting.

 

 

  • 【Usage Method】
    1. Low-temperature adsorption dip dyeing method:
      • Dosage: 0.3 - 0.7% (o.w.f)
      • Bath ratio: 1:10 - 20
      • Dyeing temperature: 95 - 100°C
      • Dyeing time: 30 - 40 minutes
      • pH value: 4.5 - 5.5 (adjusted with acetic acid)
      • Process flow: Add additives, acetic acid (to adjust pH: 4.5 - 5.5), and whitening agent into the dye bath according to the formula, heat up to 95 - 100°C at a rate of 2 - 3°C per minute, keep the temperature constant for 30 - 40 minutes, cool down, wash with water, dehydrate, and dry at 80 - 100°C. The whiteness can meet the user's requirements. If the user has a setting machine, after washing with water and dehydration, pre-dry at 80 - 100°C and bake at 170 - 175°C for 30 - 40 seconds, and the whiteness effect will be better.

    3. High-temperature and high-pressure dip dyeing method:
      • Dosage: 0.2 - 0.5% (o.w.f)
      • Bath ratio: 1:10 - 20
