Process for introducing vat dyes and chemicals into textiles

A process for using reduced vat dyes in a continuous dyeing process for production of dyed yarns and fabrics of different colors. In the process, dye composition is introduced to a treatment unit for reduction to desired dye composition. The dye concentration in the treatment unit is lower than feeding dye concentration so that dye precipitation does not occur, but significantly higher than the circulating dye concentration so that the dye is reduced efficiently. Although the preferred location for the treatment unit is before the circulation line, it may be at any location before the dip-dye tank.

Sulfur modified silanes for the elaboration of high refractive index materials

ActiveUS20090287015A1Improving dirty mark resistanceGood optical performanceSilicon organic compoundsArtificial dyesThiolSilanes
A composition having a polythiol reactant and an alkenyl silane reactant which are combined to form a polysulfide polysilane. In the process, the reactants are combined in a thiol-ene addition process driven by UV radiation. The polysulfide polysilane is then hydrolyzed and may be combined with other hydrolyzed compounds. For coatings, the polysulfide polysilane is hydrolyzed and may optionally be combined with nanoparticles. For bulk materials, the polysulfide polysilane is hydrolyzed, concentrated and heated to form a high refractive index material which can be used to form lenses.
