Method for dyeing and simultaneously finishing textile material (14) with an ammonia solution (13) containing dyes dissolved therein. The method comprises the following steps: - preparing the ammonia solution (13) containing the dyes and sending this ammonia solution to a machine (11) for processing the textile material (14); - adjusting the percentage of water present in the textile material (14) before said textile material (14) enters into the processing machine (11) so that the overall percentage of water contained in the ammonia solution (13) and the percentage of water present in the textile fibers is at maximum 20% with respect to the total weight of the solution; - entry of the textile material (14) into the processing machine (11) through safety seals (15); - impregnating the textile material (14) with the ammonia solution (13) for at least a few seconds, the textile material (14) being kept mechanically constrained between at least an entrance tensioner element (19) and an exit tensioner element (23); - squeezing out the excess ammonia from the textile material (14), still kept mechanically constrained, in order to obtain an adjustable pick-up of about 80 - 100% with respect to the dry weight of the textile material (14); - evaporation of the ammonia from the textile material (14) inside the processing machine (11); - exit of the textile material (14), dyed and dried, from the processing machine (11) through safety seals (115).
摘要:
An apparatus and method for applying textile treatment finishing agents to garments or garment work pieces is provided. The apparatus includes a rotating drum (32) and a nozzle (15) for generating a fine mist or fog of textile treatment agents inside the rotating drum (32). The apparatus can be constructed as a dedicated processing machine, or a conventional, industrial washer or dryer can be fitted with an appropriate nozzle (15) and feed lines (16, 19) to provide a dual purpose machine which can be used for its originally intended purpose, and can be selectively used for applying textile treatment agents. Uniform coverage of the surface of the garment is assured by tumbling the garments through the fog created by the nozzle means (15). By controlling the size of the droplets, and the time during which mist or fog is generated, the amount of chemical agent absorbed by the garments can be controlled. The use of the finely divided, air dispersed liquid agent avoids wasted processing chemicals and permits the use of more concentrated chemical agents.
摘要:
A non-aqueous process for dyeing a shaped article at an elevated temperature comprises causing a thin continuous film of a dye composition to flow over the surfaces of the shaped article at an elevated temperature. The dye composition temperature and the time of contact between the dye composition and the shaped article are sufficient to effectuate the dyeing of the shaped article. The dye composition comprises a substantially non-aqueous solvent, a dyestuff, and one or more additives, if needed.
摘要:
A method for treating textile material (13) to attach dyes, such as synthetic or natural dyes, or to apply bleaches to said textile material (13). The method provides a first step of pre-impregnation of the textile material (13) with an impregnation liquid and a second step of heating the impregnation liquid and the possible dyes or bleaches, through contact of said textile material (13) with at least one heated drum (20), and subsequent vaporization of said impregnation liquid, said textile material (13) being selectively movable on said heated drum (20), subjected to an adjustable pressure higher than atmospheric pressure, a strip (18) being present and exerting on said textile material (13) an adjustable pressure against the heated drum (20).
摘要:
A method for dry-cleaning garments which comprises treating the garments with a mixture of dipropylene glycol tertiary-butyl ether (DPTB) and water for a period of time sufficient to effect dry-cleaning, wherein the weight ratio of DPTB to water is at least 9:1.
摘要:
An improved technique of supplying a treating liquid for a cloth treating machine, including a method of preparing the liquid for treating cloth in the cloth treating machine and a cloth treating machine having the function. A cloth treating liquid having a predetermined concentration is prepared by inputting a powder agent for increasing the fluid friction of a solvent into a powder agent inputting/agitating section in a treating liquid circulating system of the cloth treating machine, or by inputting the powder agent into the solvent in a flow path where the solvent has a large fluid friction locally in the circulating system, and by agitating the powder agent exploiting the fluid friction. The prepared cloth treating liquid is circulated in the treating liquid circulating system to rationally treat the cloth.
摘要:
The present invention provides a process for dyeing hydrophobic polymer fibers, including the step of contacting the goods with an amount of a dyeing solution effective to dye the goods, wherein the solution comprises an amount of a terpene/terpenoid solvent and a dyestuff. The present invention also provides a composition for dissolving and dispersing a dyestuff for dyeing hydrophobic polymer fibers, including effective amounts of a terpene/terpenoid solvent for dissolving the dyestuff.
