• the preferred method for dyeing fabrics composed of cellulosic fibres or mixtures of cellulosic and synthetic fibres is to impregnate the fabric with a mixture of one or more dyes, water and solvent in a conventional dye pad bath followed by squeezing to remove excess dye liquor, or to print with a solvent-containing printing paste, and subsequently heating to evaporate sufficient water to effect dissolution of the dye, at which time the fabric is dyed.
• water is evaporated, but in an insufficient amount to effect dissolution of the dye, after which pressure and heat are applied to effect dissolution without further evaporation of water.
• Dye pastes can be prepared by conventional techniques such as by milling the dye in the presence of a dispersing agent or surfactant.
• a dyebath can be prepared by diluting the dye paste with water or with aqueous solvent. Addition of a solvent to the dye paste before addition of water may cause dye separation and usually is avoided. It will be understood by those skilled in the art that conventional additives other than a dye solvent and a dispersing agent can be present in dye baths and printing pastes.
• Further components which may be present in the printing pastes or dye baths are e.g. natural or synthetic thickeners, pigments, acids, bases and/or salts to adjust the pH to the desired value, anionic, nonionic or cationic surfactants, antifoaming and antifrosting agents, dispersing agents, fixing agents, polyhydroxy compounds, reaction products of hydroxyl compounds and isocyanates, polyesters prepared by reaction of terephthalic acid and one or more polyethylene glycols.

• the amount of dye dispersion is preferably 1 to 15 %, more preferably 2 to 10 % and in particular 3 to 8 by weight of, based on the total weight of the printing paste.
• the temperature at which dyeing or printing is effected by the instant process depends on the solubility of the dye in the dye solvent or aqueous dye solvent.
• the fibres are heated in a liquor at 125 °C to 225 °C, said liquor containing as liquid ingredients 10 to 95 % by weight of water and 5 to 90 % by weight of organic solvent.
• the cellulosic materials which can be dyed by the process of this invention include all forms of cellulose which increase in size and flexibility upon exposure to water. Suitable materials include natural fibres and purified wood pulps as well as reconstituted cellulose in fiber and film form.

• Zirconium beads (diameter 0.6 to 1 mm) are then added to the above-obtained dispersion in a glass bottle tightly closed. The bottle is then placed in a Scandex apparatus and thereby agitated for 4 hours.
• the thus obtained fine dispersion is then filtered on a conventional Buchner funnel to provide the final dye dispersion.
• Printing paste A typical run consists in the preparation of a mother paste, to which a quantity of the dye dispersion and water will be subsequently added.
• the amount of added deionised water can vary as a function of the viscosity of the dye dispersion and/or of the printing paste.
• the printing paste is applied in a classical way on the textile (CO or PES/CO) through a screen. After drying at 90°C, the textile is thermofixed at 220°C for 1 minute.
