NESTOL – LS Powder is a universal anionic dispersing agent for dyes.
Nature : Product of condensation of an aromatic sulphonic acid, anionic.
Physical form : Brownish microgranules.
Stability : Nestol – LS Powder is acid, alkali, hardness and electrolyte-resistant even under high-temperature dyeing conditions.
Compatibility : As an anionic product, it is quite compatible with all anionic and non-ionic auxiliaries.
Solubility : Nestol – LS Powder can be dissolved either by scattering it into 10 to 20 times the quantity of boiling hot water or by pouring the same quantity of hot water over it, and stirring. 20 % - 30% stock solutions can also be prepared that are clear and very stable at room temperature. They are practically neutral.
Effect : Nestol – LS Powder stabilises dye dispersions and thus contributes to increasing the degree of fastness and the levelness of the dyeing; it has no wetting or cleaning effect. In acid baths, the product has an affinity to animal fibres such as wool and silk, and also to polyamide fibres.
The stability of stock vats can be considerably improved by the addition of 5–10 g/l of Nestol - LS. The product must be added to the dye dispersion before it has been vatted.
Jig Dyeing
2 g/l of Nestol - LS is added to the dyebath to improve its stability. Nestol - LS prevents vat acid stains, e.g., when dyeing with blue dyes.
Circulating Liquor Machines and Winch Becks
To prevent the dye from forming a precipitate that is filtered out by the goods, 1–3 g/l of Nestol - LS is added. This is particularly recommended if pigmentation or semi-pigmentation processes are used.
Pad-Steam Process
2 g/l of Nestol - LS in the chemical pad prevents the agglomeration of loose dye particles in the bath. After steaming, Nestol - LS makes it easier to remove the unfixed dye. It is particularly important to use Nestol - LS during the oxidation of vat dyes. It prevents the insoluble pigments newly formed in the oxidation bath from agglomerating and being filtered out by the goods.
The addition of 1 g/l of Nestol - LS to the stock vat increases the process reliability.
Concentration required 0.5–2 g/l. The quantity of Nestol - LS required depends upon the type of dye preparation. If low-dispersant liquid dyes are used, the addition of Nestol - LS is particularly important to ensure the stability of the dye dispersion during the whole dyeing process. If a short-liquor ratio is used, the application quantity is increased because the risk of agglomeration is greater. During the dyeing process, Nestol - LS not only stabilizes the dye dispersion but also prevents the agglomeration of the dye particles that remain behind in the liquor when the bath cools down.
Clearing of Prints
Concentration required 1–1.5 g/l. Nestol - LS is particularly recommended for clearing prints made with disperse dyes on blends of acetate and/or triacetate and polyamide. It prevents the transfer of dye to the polyamide component during washing.
Concentration required 0.5–1 g/l. Due to its anionic nature, Nestol - LS has an affinity for cationic dyes and is often used as an additive in clearing baths.
