摘要:
Process for the pad-dyeing and printing of textile material made from mixed fibres of cellulose and polyester, which process comprises impregnating of printing the textile material with a dispersion of a disperse dye containing at least one hetero atom which can be alkylated; treating the textile material, before, during or after the impregnating or printing operation, with a compound containing at least two epoxy groups or groups convertible into epoxy groups; and subjecting the material impregnated or printed with dye and epoxy compound to a heat treatment.

摘要:
Described is a process for the level dyeing of polyester material by the aqueous exhaust method at temperatures above 100.degree. C., which comprises the use of an aqueous dye liquor which contains at least one migrating disperse dye as well as further ingredients. As migrating disperse dye, preferably a dye is used which has a diffusion coefficient Do at 130.degree. C. of 2 to 10.times.10.sup.-10 cm.sup.2 /sec, a distribution coefficient K at 130.degree. C. of 20 to 500 1/kg, and a migration half-life t/2 less then 50 minutes.
摘要:
Described is a process for the processing of organic textile materials by application of an aqueous dispersion or solution of a processing agent having affinity for the fibres, with a ratio of goods to liquor of at most 1:2, and subsequent fixing of the processing agent by means of a steam treatment, characterized in that the ratio of goods to liquor of the applied liquor is increased, below the absorption temperature of the processing agent, by the admission of saturated steam in such a manner that the processing agent is uniformly dispersed on the material before commencement of the fixing process.The advantages of this process are that there are used practically no products contaminating the waste liquors, particularly no surface-active substances tending to form foam, and that there are nevertheless obtained perfectly satisfactory processing effects. Surprisingly, moreover, irregularities caused by the material are levelled out during dyeing.

摘要:
The invention describes a process for the HT dyeing of polyester fibre material with dyes which are sparingly soluble in water, which process comprises the use of a dyebath which contains at least one block polymer of ethylene oxide and propylene oxide having a molecular weight higher than 5000.The use of such a polymeric non-ionic dispersant ensures, even in low concentration, the stability of the dye dispersion under HT conditions, with at the same time substantial to complete bath exhaustion.
