Definitions

• This invention refers to a process for the simultaneous desizing and dyeing of synthetic fibres and their mixtures, in general, and, more specifically, in polyester fibres and their mixtures with viscose and in polyamide fibres and their mixtures with elastomer fibres.
• the invention develops a dyeing system without having to carry out prior boiling out and desizing, with the resulting savings in material, energy and time compared to conventional methods.
• the invention is based on the development and application of a new detergent/humectant surfactant with a dispersant effect much greater than those known and used at the present time.
• these fibres are deoiled and desized in weakly alkaline media, for example, in a sodium carbonate solution in the presence of non-ionic detergents, operating at temperatures from 80 to 100°C, in the case of pure polyester fibres, and at lower temperatures in certain mixtures with other natural or synthetic fibres.
• Plastosoluble dyes and disperse dyes which are incorporated under pressure at a high temperature are used for dyeing these fibres, amongst others.
• Polyamide fibres are desized in strongly alkaline media at 80-100°C. Acid type dyes are used for subsequent dyeing, in the presence of combining agents and at temperatures between 100 and 110°C in circulation machines.
• Elastomer fibres are desized in a reducing acid medium, using a non-ionic detergent medium. They are usually boiling dyed with the purpose of increasing dye permeability whilst the medium's acidity is maintained.
• two large groups of dyes may be distinguished for dyeing, water soluble and insoluble dyes, using processing technologies in a discontinuous or continuous treatment in machines at atmospheric pressure or low pressure at temperatures over 100°C.
• a discontinuous or continuous treatment in machines at atmospheric pressure or low pressure at temperatures over 100°C.
• there are machines with bath circulation or with material circulation and dyeing at high temperature is usually performed in an autoclave working by bath circulation.
• the wet, discontinuous treatment is performed by making the textile fabric continuously circulate in the form of a cord through nozzle or jet staining facilities.
• the agent is made up on the basis of an alcohol with 8 to 14 carbon atoms with 2 to 10 ethylene oxide moles plus 1 to 7 propylene oxide moles, mixed with an alcohol between 7 and 15 oxyethylenated carbon atoms with 1 to 8 moles of ethylene oxide and then phosphated and/or phosphorylated.
• the process time is reduced by over 1 hour, since the prior boiling out used in the conventional process requires an estimated time of 1 hour 50 minutes, and there is also a saving in water estimated at 30 litres/kg of material, since the water used in the process according to this invention is the same as that in the dyeing process.
• Another advantage consists in the reduction in the amount of acid necessary to obtain a suitable pH for dyeing.
• a reduction in differential pressures occurs in autoclave dyeing, as a result of the effect that the surfactant which is the subject of this invention produces on the sizers and other materials or dirt.
• filtrates from the sizing agent which are produced at the bottom of the packet are totally removed.
• the new process described in this specification represents a reduction in processing time by about 4 hours in comparison with known processes, and a reduction in water consumption by 30 litres of water per Kg. of material treated.
• the apparatus is filled by adding the surfactant at a concentration of 1.5 gm./litre and the textile material is then loaded, heating to 50°C at a heating rate of 2°C/minute, keeping it in circulation for 5 minutes.
• One percent (1%) of a levelling/dispersant agent is then added, formed by a mixture of an ethoxylated fatty acid with non-ionic surfactants or on the basis of a linear polycondensate in an aqueous solution, 0.3 to 1.0% of a fold/sliding inhibitor agent on the basis of alkylenepolyglycolether oleate and acetic acid to obtain a pH of 5.
• a variant on Example 1 is to fill the apparatus initially with 1.5 gm/litre of surfactant and 0.3-1% of the fold/sliding inhibitor agent on the basis of alkylenepolyglycolether oleate.
• the textile material is loaded, and the temperature is raised up to 50°C by heating at 2°C/minute and keeping it in circulation for 5 minutes, then adding 1% of one of the levelling/dispersant agents described in example 1, adjusting the pH to a value of 5 with acetic acid and circulating the material for another 5 minutes.
• a suitable percentage of the dispersed dye is added, the temperature is raised up to 130°C by heating at a rate of 2°C/minute and the system is kept at 130°C for 30-45 minutes, after which it is cooled down to 80°C, emptied, washed and discharged.
• This example is a modification of Example 2, when some types of acrylic sizers are used.
• the apparatus is filled with 1.5 gm/litre of the surfactant, 0.3-1% of the fold/sliding inhibitor agent and 1% of any of the levelling/dispersant agents described in example 1.
• the pH is adjusted to between 4.5 and 5 with acetic acid and the system circulated for 5 minutes at 50°C.
• the required percentage of dispersed dye is added, the temperature is raised up to 130°C by heating at a rate of 2°C/minute.
• the system is maintained at 130°C for 30-45 minutes and then cooled to 80°C and 4 gm/litre of sodium carbonate is added and the system circulated for 10 minutes, after which it is emptied, washed and discharged.
• the apparatus is filled with 1.5 gm/litre of the surfactant and loaded with the textile material.
• the temperature is raised by heating to 40°C at a rate of 2°C/minute and circulating for 5 minutes.
• One percent (1%) of levelling/dispersant agent on the basis of a mixture of ethoxylated fatty acid with non-ionic surfactants, 0.3 to 1% of the fold/sliding inhibitor agent on the basis of alkylenepolyglycolether oleate or a levelling/fold inhibitor agent on the basis of a sulphonated fatty acid and acetic acid to fix a pH of 5 are added, and the system is circulated for 5 minutes.
• the required percentages of the dispersed dye and the direct dye are added, then the temperature is raised up to 130°C by heating at 2°C/minute, keeping the system at this temperature for 15 to 40 minutes and then cooling to 60°C, emptying and washing, fixing if necessary and finally discharging.
• the apparatus is filled by adding 1.5 gm/litre of the surfactant, loading the textile material and heating to 50°C at 2°C/minute. At that temperature, the system is circulated for 5 minutes and 1% of a levelling/dispersant agent on the basis of a blend of ethoxylated fatty acid with non-ionic surfactants and 0.3-1% of a fold/sliding inhibitor agent on the basis of alkylenepolyglycolether oleate are added and the pH is adjusted to 5 using acetic acid. After 5 minutes, a suitable percentage of the dispersed dye is added, heating to 130°C at 2°C/minute, maintaining the system for 30 to 45 minutes after which it is cooled to 80°C, emptied and washed.

• the textile material is loaded, the temperature is raised to 30°C, circulating is performed for 5 minutes after which a suitable percentage of the levelling agent, acetic acid, 1.5 gm/litre of sodium acetate, 0.3 to 1% of a fold/sliding inhibitor on the basis of alkylenepolyglycolether oleate and a suitable percentage of acid dye are added. It is heated to 110°C at 1°C/minute and this temperature is maintained between 45 and 60 minutes and then cooled down to 60°C, and the system is emptied, washed and finally discharged.
