Abstract:
A substrate such as a woven or nonwoven fabric bound with a light-activated dye alone or in combination with additional conventional antimicrobial agents. The substrate is impregnated with a light-activated non-leachable dye having antimicrobial and/or antiviral characteristics which can be imparted to the substrate. The dye is bound by a cationic or anionic binder such as a water soluble polymer or carrageenan. Upon exposure to normal light, the dye generates singlet oxygen that kills microorganisms and viruses.
Abstract:
Use of the customary dyes for the type of fibre in question and using the customary dyeing and/or printing processes for the type of fibre in question for minimally reducing, retaining or increasing the NIR reflectance, preferably increasing the NIR reflectance, in the region of electromagnetic radiation of wavelength 700 nm to 1100 nm of textile material in relation to the undyed and untreated textile material, characterized in that metal-free dyes are used.
Abstract:
The invention concerns a dyeing composition for keratinous fibres, in particular for human keratinous fibres such as hair, comprising, in an appropriate dyeing medium, at least a cationic direct colouring agent of specific formula, and characterised in that it further contains at least a silicone selected among amine silicones, polyalkylene silicones, silicone gums and resins. The invention also concerns methods and devices using said composition.
Abstract:
The present invention relates to a composition for printing a fiber blend, yarn, woven or non-woven or knit fabric comprising or consisting of at least acrylic, aramid, and optionally wool, a process for producing the composition, use of the composition, a process for printing said fiber blend, yarn, woven or non-woven or knit fabric, as well as to the printed fiber blend, yarn, woven or non-woven or knit fabric and the use thereof to manufacture goods like cloths therefore.
Abstract:
A dyed substrate having at least one dyed surface. At least one dye solution is disposed across at least a portion of the surface in combination with a migration promoting composition and/or a migration limiting composition. The migration promoting composition and/or migration limiting composition adjusts the migration of at least a portion of the dye solution across the substrate in a controlled manner. Dye migration may be arrested by the application of RF (radio frequency) energy as a step in dye fixation. A process for forming the dyed substrate is also provided.
Abstract:
The invention concerns the use as direct dyeing agent of at least one tetra-azapentamethine compound, a dyeing composition comprising at least such a compound, as well as a method for dyeing keratinous fibers, in particular human keratinous fibers and more particularly hair, which consists in applying at least one composition comprising such a compound. The composition also concerns tetra-azapentamethine compounds of formula (I). The invention further concerns a method for bleaching such compounds, as well as bleaching keratinous fibers previously dyed therewith.
