VERNIUM POLY 4460

Dyeing Auxiliaries

Dyeing polyester fibers and polyester/cellulose blends at all stages of processing in HT processes on jets and circulating liquor machines. Dyeing of yam and pieces for automotive textiles, together with UV-FAST APS or UV-FAST HLF as light fastness improver Dyeing polyester/cellulose blends in one-bath-two- steps method. Dyeing of polyester in HT rapid dyeing methods. Dyeing polyester fibers at all stages of processing with high density.

CHARACTERISTICS

Unequaled spectrum of effects like dispersing,levelling and migration
Excellent dispersing properties
Outstanding levelling properties
Good migration properties
Increased dye yield

BENEFITS

Easy application to secure highest reproducibility in various dyeing methods
Improves dispersion stability of the dyes in the bath and prevents agglomerations. Prevents filtration on packages with high density No extra dispersants required
Permits level dyeing under critical dyeing conditions, e.g. in polyester HT rapid dyeing Improves in out levelness in dyeing on circulatiing liquor machine. Suitable for levelling faulty dyeing.
Hence both fiber and surface levelness, ensures uniform shade build up
Rapid and safe achievement of the final shade also in rapid dyeing processes. Reduced amounts of dyes in the effluent

0.5-2.0 WI VERNIUM POLY 4460

Notes

For dyeing polyester at high temperatures, 0.5-1.0 _g/l VERNIUM POLY 4460 levelling agent is usually enough.

An excellent fiber and surface levelness improver, VERNIUM POLY 4460 levelling agent is suitable for all polyester HT dyeing methods, and overcomes the problems associated with high wind density packages. tightly woven piece-goods or hard-t o-level dyes.

With extremely rapid rates of heating. very short liquor ratios and deep shades, a diffusion accelerant such as VERNIUM POLY 4460 should be present in the bath. Treatment with higher amounts of this products is an excellent way to correct unievel dyeing,

If polyester/cellulosic and polyester/wool blends are dyed in presence of VERNIUM POLY 4460 levelling agent, the non-polyester component is largely protected against staining by the disperse dyes.
