AVCO-LUX ETB/ ETBN

AVCO-LUX ETB/ ETBN

Rainbow is Avco preferable colour!

AVCO-LUX ETBN is an ideal optical brightening agent for polyester with high whiteness, low dosage and bright color shade. Mainly used in whitening and brightening of polyester and its blends by the thermosol and exhaust methods.
AVCO-LUX ETB is a tinted version of AVCO-LUX ETBN with more violet-bluish shade.

Properties & uses:

  • Produces excellent white effects of a neutral to violet-bluish shade on polyester fibres, when applied by the thermosol process at temperatures of 160 – 200°C, or by the exhaust method, particularly under HT conditions at temperatures of 110 – 135°C
  • Very good white effects are obtained even at fairly low temperatures due to the high fixation capacity
  • Excellent white effects are achieved on texturized polyester goods in the thermosol process at temperatures as low as 150°C,taking into account the normal dwell times. Such articles are thermosoled at temperatures between 170 – 180°C
  • Very suitable for the brightening of the polyester component in polyester/cellulosic blends. The brightener can be applied to the fibre before, during or after peroxide bleaching
  • Polyester/cotton goods brightened with the product can be subsequently bleached with chlorite without any problems, the product is fast to chlorite in this case. It is not recommended to apply during chlorite bleaching
  • Very good effects are also achieved by applying together with resin finishing agents by the shock curing method to goods ready for finishing. Magnesium- chloride or a commercial shock curing catalyst are normally used as the catalyst for the reactant resins used in this process. Zinc salts such as zinc nitrate or zinc chloride may impair the white effect obtained with the product when shock curing is the method used. A preliminary trial is therefore recommended
  • The product produces attractive white effects on burn-out articles especially if the burning-out process is followed by chlorite or hypochlorite bleaching
  • The white effects can be further improved by applying the optical brightener under HT conditions by the exhaust method in the presence of a dispersing agent such as AVCONAL BM. When brightening is carried out at temperatures near boiling, the addition of a suitable carrier produces somewhat higher degrees of whiteness than just a dispersing agent
  • Over dosing is causing yellowing of the optical brightening effect
