摘要:
Compounds of the formula ##STR1## wherein R.sub.1 is a benzene or naphthalene diazo component,R.sub.2 is cyano or acyl, andR.sub.3 is phenyl, naphthyl or heterocyclyl, or a substituted derivative thereof, with the proviso that the molecule is free of sulfo groups,Have low solubility in water and are highly suited for dyeing and printing fibers and textiles of synthetic and semi-synthetic, hydrophobic, high molecular weight polymers such as polyesters, cellulose diacetate, cellulose triacetate and polyamides. The obtained dyeings are fast to light, sublimation, thermofixation, pleating, wet treatments, etc. and are stable to permanent press finishing.
摘要:
A print paste for printing textiles of polyester, cellulose acetate, cellulose triacetate and mixtures of the same with other fibers which is based on a disperse dye, thickener, ethanolamide of a carboxylic acid and water and which is characterized by a content of at least one phenol which has been oxyethylated twice to six times. The paste yields prints having excellent color strength and levelness.
摘要:
A new non-foaming composition which is useful for a substantially crease-free dyeing of polyester fibers and comprises a dyeing assistant and a surface-active glyceride.
摘要:
Process for dyeing textiles made of polyester or cellulose triacetate with dispersed dyes, in an aqueous medium, whereby the dyeing is carried out with the concurrent use of 0.5 - 10 c.c./1. trichloroethylene and/or perchloroethylene as carrier and an emulsifier, with pressure and temperatures above 100*C..
摘要:
An anthraquinone dyestuff of formula is provided. The dye is made by heating the sodium salt of p-cresol with 1-amino-2-bromo-4-hydroxy anthraquinone at 150-155 DEG C. for 5 hours. Red dyeings on polyester material are obtained.ALSO:The invention provides a process in which polyester materials are dyed with a disperse dye of formula Conventional dyeing processes are used employing a carrier and nonionic dispersing agents, red dyeings are obtained.
