| titleOfInvention | Finishing pigment-resin coloured fabrics |
| abstract | Textile fabrics are coloured over at least a portion of the surface by a light-fast pigment applied thereto by depositing a pigment-resin emulsion thereon and curing the resin, and after-treating at least the pigment-coloured portion with an aqueous solution of an amide-or imide-aldehyde resin alkylated with a polyhydric alcohol and thereafter heating to destroy the water-solubility of the resin. The after-treatment resin must be water-soluble both before and after alkylation. At least a portion of the remaining surface may be dyed or over-printed with an organic dyestuff. Suitable amide- and imide-aldehyde resins are obtained by condensing an aldehyde such as formaldehyde with urea, thiourea, guanidine, biuret, dicyandiamide and melamine, and alkylating with a polyhydric alcohol such as a glycol, glycerol, pentaerythritol, di-pentaerythritol, sorbitol and mannitol. In an example: (1) a pigmented colour base containing iron oxide yellow pigment, soyabean oil-modified glycerolphthalate resin, a solution of butylated dimethylol urea in xylene/butanol, pine oil, oleic acid and ammonia is reduced with an oil-in-water emulsion of a petroleum fraction in aqueous methyl cellulose solution. Cotton cloth is dyed or printed with the pigmented emulsion, dried and heat cured and finished by passing through an acid aqueous solution of a urea-formaldehyde resin alkylated with ethylene glycol, drying and heating to 120 DEG C. for 3 mins. In example (2), the process is repeated, but using a finishing solution comprising an acid aqueous solution of urea-formaldehyde resin alkylated with glycerol. In example (3), a pigmented colour base containing copper phthalocyanine, a soyabean oil - modified glycerol-phthalate resin dissolved in a petroleum fraction boiling at 160 DEG to 250 DEG C., low viscosity ethyl cellulose, butanol, tricresyl phosphate and aluminium hydrate is blended with a solution of butylated dimethylol urea in petroleum oils reduced with a water-in-oil emulsion containing sodium lignin sulphonate, a soyabean oil-modified glycerol-phthalate resin, toluene, a mixture of petroleum fractions, and acetic acid, and printed or dyed on a cotton fabric. The fabric is then dried and heat cured, finished with an acid aqueous solution of a melamineformaldehyde resin alkylated with ethylene glycol, dried, and heated to 120 DEG C. for 3 mins. In example (4), a pigmented colour base containing dichlorobenzidine yellow, the sodium salt of disulphodinaphthyl methane, bentonite, dimethoxymethyl urea, trimethylol melamine and methyl cellulose is mixed with an oil-in-water emulsion containing a petroleum fraction, methyl cellulose and trimethylolmelamine, and dyed or printed on a cotton fabric, which is dried and heated, and finally treated by passing through a solution of urea-formaldehyde resin alkylated with ethylene glycol, drying and heating to 120 DEG C. for 3 mins. |
