Abstract: The present invention discloses methods and kit-of-parts for treating keratinous fibres prior to dyeing to control and modulate dye uptake into the fibre. Organic solvents having log P of from ?4.0 to ?0.5 or from 0.5 to 4.0 are used to manufacture pre-treatment composition to be applied to the hair. When the hair is pre-treated with at least one organic solvent having a log P of from 0.5 to 4.0 the dye penetration into the keratinous fibres is enhanced, while pre-treating the hair with at least one organic solvent having a log P of from ?4.0 to ?0.5 reduces the dye uptake. One or more compositions to pre-treat the keratinous fibres can be effortlessly applied on different zones of the hair and can be left in place or removed prior the application of the dyeing composition.

Abstract: The present invention relates to methods of imparting color and ultraviolet protection to synthetic yarns or substrates. More specifically, the present invention is directed to a method of solution dyeing a polymeric material during polymerization to form a base color shade, and subsequently dyeing the polymeric material by either yarn dyeing or piece dyeing. Ultraviolet protection is also provided in the solution dyeing step, by introducing an ultraviolet stabilizing agent into the polymer. The base shade may then be transformed into a useful color pallet with enhanced lightfastness properties by applying a final color shade late in the fabric formation process.

Abstract: The present invention provides a non-aqueous process for the dyeing of a dyeable material at an elevated temperature by contacting a dyeable material with a dye composition at an elevated temperature in a non-reactive environment. The dye composition temperature and the time of contact between the dye composition and the dyeable material are sufficient to effectuate the dyeing of the material. The dye composition comprises a substantially non-aqueous solvent and a dyestuff.

Abstract: High-tenacity nylon fabrics are dyed in a multi-step continuous aqueous dyeing process. Uniformly dyed fabrics having a high degree of fiber bundle penetration result.

Abstract: A process is described for the continuous dyeing of textiles in which an aqueous solution of an ionic, water-soluble dye is applied to a fabric in open width. The textile is dried to reduce the water content to at most about 1% and it is then contacted with a nonionic, high-boiling organic liquid in which the ionic dye is substantially completely insoluble while the liquid is maintained at an elevated temperature, i.e., about 325.degree. F.-450.degree. F., for a period of time sufficient to cause the dye to diffuse into the fibers and to fix the ionic dye to the fibers of the textile. Any remainig high-boiling liquid is subsequently removed from the fabric.

Abstract: Textile fabrics are dyed in open widths in a closed, heated environment by spraying a heated dye composition containing a dyestuff dispersed in a non-aqueous, high-boiling solvent, without the dye applicator directly contacting the fabric, directly onto the fabric. The sprayed fabric is held under transverse tension in a heated (350.degree. to 450.degree. F.) environment and further heated while the sprayed dye dispersion migrates, penetrates thoroughly through the fabric and levels substantially evenly across the width of the fabric. Fabrics are thus simultaneously uniformly dyed and uniformly heatset. Apparatus for conducting the process is also disclosed.

Thereafter, the fiber can be dyed or printed with an anionic dye. A solution of the solvent and substance may be prepared, and the fiber contacted with the solution.

Abstract: A process for the preparation of a woven fabric of low air permeability which comprises preparing a woven fabric by use of a composite fiber of a splitting and severing type, which consists of polyester and polyamide and produces extremely fine fibers of 0.001 to 0.8 denier size, as a warp and/or a weft; treating thus obtained woven fabric by use of an aqueous emulsion of a swelling agent for polyester and nylon under the conditions where nylon is mainly allowed to swell and then shrink; scouring and dyeing the woven fabric; and after calendering the woven fabric with the use of heated rollers rotated under pressure.

Abstract: The process for the visible marking of carrierless polymeric membranes for filtration purposes and for the reverse osmosis is characterized in that the marking symbols are first of all printed onto the casting support, onto which subsequently the casting mass is poured which serves for the production of the membrane. During the removing of the pre-solidified, solidified or finished membrane from the casting support, the printing dye which has an outline corresponding to the marking symbols, is taken up by the membrane and is taken along by the latter from the casting support. Preferably, the printing dye which had been imprinted onto the casting support when the membrane casting mass is poured on, has at least dried in a wipe-proof manner and, in this state, is soluble in the solvent-system of the membrane casting mass.

Abstract: The present invention involves an improved levelling agent and a method of using it in the disperse dyeing of hydrophobic synthetic fiber materials such as polyesters and polyamides. The levelling agent enhances dye migration without substantially accelerating the exhaustion of dye onto the fabric being dyed. It is based on diaryl ethers such as ditolyl ether mixed with emulsifiers and optionally a diluent which is water or an organic solvent.It also involves a process for improving the levelness of already dyed materials by subjecting them to temperatures above the boiling point of water in the presence of diaryl ether based levelling agents.
