The invention relates to dyestuff preparations comprising water, a water-insoluble or sparingly water-soluble dye, a dispersant, a humectant, and optionally further additives, wherein said humectant is a compound of the formula I ##STR1## wherein R is a C.sub.1 -C.sub.16 alkyl group which is unsubstituted or substituted by OH, CN, halogen or --N(C.sub.1 -C.sub.4 alkyl).sub.2, and R' is hydrogen or the --CH.sub.2 --CHOH--CH.sub.2 OH group.These preparations are suitable for use in aqueous or aqueous-organic dye liquors or printing inks or also for obtaining printing pastes. After partial or complete dehydration they are also very readily redispersible.

摘要:
New solid dyestuff preparations are disclosed consisting of an anionic dyestuff having a particle size of less than 10.mu., a dispersing agent, a basic component, especially sodium bicarbonate, a solid acid component, preferably tartaric acid, as well as, optionally, further additives.The new dyestuff preparations are stable in storage, and have good solubility in water, they are therefore extremely suitable for the preparation of aqueous dye liquors.
摘要:
Stable dust-free commercial preparations of organic substances are described, which preparations comprise an organic substance especially a dyestuff or optical brightener in dry powder form enclosed in a covering, particularly in a sack or bag sealed on all sides, made from polyethylene oxide having a molecular weight of more than 200,000 and a thickness of 10 to 80.mu., which covering is soluble in the same medium as the content.
摘要:
The present invention concerns new fluid and stable dispersions of anionic dyestuffs, containing(a) dispersed anionic dyestuff with a maximum particle size of 5.mu.,(b) a dispersing agent which comprises(i) a combination of at least two different anion-active dispersing agents or(ii) a combination of an anion-active dispersing agent and at least one wetting agent or(iii) a combination of at least two different anion-active dispersing agents and at least one wetting agent,(c) optionally further auxiliaries and(d) water,As well as a process for their production and their application to dyeing and printing of organic material, in particular fibre material of natural and synthetic polyamide.
摘要:
Disclosed is a solid preparation containing at least one anionic dye or optical brightener, at least one anionic compound having hydrotropic activity, and/or at least one anion-active solubilising agent as well as optionally further additives, such as and preferably a anti-dust agent, whereby this preparation has a very good solubility especially in cold water compared with that of equally strong dyes diluted with customary fillers and can be used for producing aqueous dye preparations useful for dyeing and printing materials dyeable with anionic dyes or optical brighteners.
摘要:
Solid non-dusty, porous dyestuff-foams are described of any desired shape and size containing at least one dyestuff, a foaming agent and optionally bonding agents and/or further additives.These foams are useful for preparing dye liquors or printing pastes by sprinkling said foams into water or organic solvents.
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.
摘要:
An improved process for the production of granules, comprising application of a granulating liquid to a pulverulent substance being subjected to a rotating movement in such an amount that the point of equilibrium between the moisture content of the substance and that of the air is exceeded, and subsequently drying this moist substance until its moisture content falls to or below this point of equilibrium.
