LEVINOL-300 : It is a low foaming leveling agent suitable for dyeing polyester fabrics. During exhaust dyeing it increases the solubility of disperse dyes, which ensure a better distribution of the dyes during the heating process. It is a high performance polyester leveling agent, showing excellent dispersion of disperse dyes.
FEATURES:
- Ensures coefficient exhaustion of disperse dyes
- Excellent retardation of dyes during the initial dye strike
- promotes leveling-out in the HT phase
- Minimizes marking caused by variations in the affinity of the material
- Retarding is reversible at high dyeing temperatures
- Good solubilising and dispersing effect of disperse dyes. Superior oil emulsification compared to conventional levelers
- Excellent oligomer dispersion
- No addition of dye bath lubricant necessary
- Stable to high salt addition during disperse/direct cycle
- LEVINOL-300 behaves as hydrotropic agent i.e., it has a solvating type of effect on Disperse dyes, water being solvent to LEVINOL-300 & non solvent to disperse dyes, reduces effectively the particle size & leveled dyeing & uniform dyeing and prints are obtained.
- While printing, spun by texturised variety, in case of medium brown or olive type shades, it is generally observed that dye pick up level of spun & texturised yarn is different. On separating warp & weft yarns it is seen that dye on spun yarn is yellower as compared to that on texturised (which is comparatively bluish). These type of effects are due to differential heat treatment received during heat setting & texturising. Such differential dye pick up is minimized by LEVINOL-300

LEVINOL-300: APPLICATION:
APPLICATION : JET DYEING / BEAM DYEING :
 Add acetic acid & dye as usual.- Add 0.5% (w/w) of LEVINOL-300
- ---circulate & continue dyeing as usual.
PRINTING:
1. Make gum paste as usual.
2. Adjust the pH to 5.5 using Citric Acid.
3. Add 0.5% LEVINOL-300(o.w.p.) and mix well.
4. Prepare the colour paste as usual using the above paste.
