摘要:
The present invention relates to an aqueous dispersion containing (a) a fluorescent whitening agent, (b) a dispersing agent, (c) a β-1,3-glucan and, optionally, (d) a vat dye and the use of the aqueous dispersions for whitening synthetic fibres, in particular polyester and polyacrylonitrile.
摘要:
The present invention relates to a composition comprising a fluorescent whitening agent and a tertiary alkanolamine, a stable aqueous solution of such a composition and use of such composition for the bleaching of textile fibres or paper.

摘要:
The present invention relates to a process for optical brightening of synthetic fibers or of synthetic fibers in a blend with natural fibers by treatment in a treatment bath to which a microemulsion was added and which as well as water comprises the components to be brightened. The microemulsion comprises nonionic surfactants, ionic surfactants, organic solubilizers and water.
摘要:
The invention relates to a water-soluble copolymer having at least one alkoxy or hydroxyl polyalkylene glycol function grafted onto at least one ethylenically unsaturated monomer, as an agent to improve the activation of the optical brightness of the end product, in the fields of paper, textile, detergents and paint.
摘要:
Aqueous dispersions (U) containing: (A) a UV-light-absorbing textile treatment agent and (B) a dispersant system containing (BX) a non-ionogenic, polymeric, hydrophilic dispersant or a mixture of such dispersants and (BY) a non-ionogenic or anionic, vinyl-polymeric, hydrophilic thickener or a mixture of such thickeners, and optionally at least one of the following further components: (BZ) at least one non-ionogenic or anionic surfactant other than (BX) (BW) at least one dispersing auxiliary other than (BY). (C) by-products and/or concomitants (D) at least one formulation additive and (E) at least one agent for setting the pH are particularly stable and are very useful for the UV-active finishing of textile material.
