ZETESAL 2000 - Zschimmer & Schwarz

ZETESAL 2000Aftertreatment agent for reactive dyeings and printingsto achieve excellent fastness to washingChemical compositionquaternary ammonium compoundCharacteristicsAppearance:colourless up to pale yellowish liquidIonicity:cationicSolubility/Emulsifiability: readily soluble in cold and warm waterpH-value of 10% solution: about 3Resistance:compatible with cationic and non-ionic products; not compatible withanionic substances; resistant to acids, alkalis and electrolytes inusual concentrations as well as to hard waterStorage:at least 12 months if properly storedStability to frost:not sensitive to frostApplication propertiesThe effect of the product is based on the absorption of the product by the fibre in a substantiveway and on forming a compound with the dyestuff. A reduction of the dyestuff solubility in water isthe result.• excellent improvement of the wash fastness• effects are fast during washing at the boil• significant wet fastness improvement in case of dark red and navy blue shades• impedes rehydrolysis of the fixed reactive dyestuffs• negligible influence on light fastness and shade• no influence on the touch• free from formaldehyde• conformity with Oeko-Tex Standard 100• GOTS approvedApplication fieldsZETESAL 2000 is applied in order to improve the wet fastness properties of reactive dyeings andprintings of cellulose fibres.• applicable along with softeners in a single-bath two-step process• compatible with high-grade finishing liquors• applicable to Indosol dyeings• applicable to selected sulphur dyeings (hydron blue)• improves fastness to rubbing of indigo warp dyeingsThe above results have been obtained from trials in our laboratory and plant.
