Definitions

  • the present invention concerns a process for the treatment with liquid ammonia or with a liquid ammonia solution of woven fabrics, non-woven fabrics, knitted fabrics, yarns, slivers or tow based on cellulosic, animal, artificial or synthetic fibres, or relatively mixed ones.
  • Liquid ammonia treatment of cellulosic fabrics gives considerable advantages, among which the following may be listed: improving of the dyes affinity, improving of the dimensional stability, improving of wash and wear characteristics, softer touch, prolonged maintenance of the "new aspect", even after several washes, higher resistance to abrasion and tear. It is also known that liquid ammonia treatment is particularly complicated. In fact, ammonia has a suffocating odour and may not be released into the atmosphere, as a concentration of only 150-200 ppm is high enough to cause serious irritation of the eyes and of the respiratory tract. According to the current state of the art technology, fabrics are impregnated by means of liquid ammonia, which is then removed from same by evaporation or washing.
  • liquid ammonia treatment plants currently in use cannot be used to treat knitted fabrics or yarns; moreover, they are unable to properly control the percentage of impregnation of the textiles with liquid ammonia_and, finally, they cannot effectively compensate for the high shrinkage of cellulosic fabrics, which is due to fibre swelling.
  • a warp and weft cotton fabric weighing 180 g/sq.m, not mechanically bound will undergo the following amounts of shrinkage: - 120% liquid ammonia impregnation; 15% shrinkage after 8 seconds
  • Document JP 10 088 465 describes a machine that carries out the treatment with liquid ammonia of cellulosic yarns wound on cones. In this case, the absorption of liquid ammonia on the outer part of the cones and the swelling of the fibres generate very high pressure on the inside of the cones, due to which this treatment is extremely uneven.
  • Document US 5 953 780 describes a machine for dyeing synthetic yarns or webs, wound on reels, with dyestuff dispersed in a supercritical liquid, such as carbon dioxide or liquid ammonia. This system does not offer the possibility to control the impregnation percentage and involves high energy costs.
  • Document GB 854 221 describes a machine for dyeing fabrics wound around a drum, which can rotate at adjustable speed.
  • liquid ammonia is used in order to apply the dyestuff to a web.
  • the fabric is padded, at atmospheric pressure, with dyestuff dispersed in liquid ammonia. Subsequently, the liquid ammonia is evaporated and the dyestuff is fixed by means of a thermal treatment or by steaming.
  • the purpose of this invention is to create a process for the treatment with liquid ammonia or with liquid ammonia solutions of woven fabrics, non-woven fabrics, knitted fabrics, yarns, slivers or tow based on cellulosic, animal, artificial and synthetic fibres and relatively mixed ones, free from the problems mentioned above.
  • the textile products to be treated can be raw, bleached, dyed or resin-finished, either thoroughly dried or slightly moistened.
  • this invention can be used in the finishing and dyeing of woven fabrics, non-woven fabrics, knitted fabrics, slivers or tows based on cellulosic fibres (such as cotton, flax, ramie, hemp%), or animal fibres (such as wool, mohair, alpaca, silk%), or artificial fibres (such as polynosic, viscose, acetate, triacetate%), or synthetic fibres (such as polyester, acrylic, polyamide, micro-fibres%), as well as on combinations of relatively mixed fibres.
  • cellulosic fibres such as cotton, flax, ramie, hemp
  • animal fibres such as wool, mohair, alpaca, silk
  • artificial fibres such as polynosic, viscose, acetate, triacetate
  • synthetic fibres such as polyester, acrylic, polyamide, micro-fibres
  • this is obtained by impregnation of the textiles with liquid ammonia, or with a liquid ammonia solution, in an adjustable percentage of between 0.1% and 200% by weight of the textiles, said textiles being placed in a vessel which houses a drum around which the textile material is wound and said drum being located along the longitudinal axis of the vessel.
  • the vessel which obviously is to remain closed for the entire duration of the treatment, prevents the leakage of ammonia into the atmosphere.
  • the working pressure inside the vessel can be the either the same as the atmospheric pressure, or below or above it.
  • Figure 1 is a schematic longitudinal view of a vessel inside which the process referred to in this invention is carried out.
  • Figure 2 is a schematic cross-sectional view of the above.
  • jacket (can be replaced with a technical heat exchanger)
  • the process in this invention involves the use of a vessel 1, housing a drum 2 with holes on its side surface.
  • Said drum 2 is placed along the longitudinal axis of vessel 1 and, to advantage, it can be made to rotate about its axis for the purposes specified hereinafter.
  • the textile product 3 is wound around said drum 2, with a predetermined and controlled tension.
  • the thickness of the textile product clearly wound up in coils can be adjusted based on the type of article and relevant finishing process.
  • the textile product 3 and a blanket can also be wound together around drum 2. It can be useful to use a blanket, such as a synthetic satin one, which, thanks to its smooth surface and excellent permeability, will ensure excellent surface finishing of the fabrics.
  • liquid ammonia solution we mean liquid ammonia with water and/or with finishing chemical products and/or with ammonia salts and/or with solvent and/or with alcohol and/or with glycol and/or with urea and/or with dyes and/or with caustic soda.
  • the liquid ammonia or a liquid ammonia solution is then fed to the vessel in the liquid state from tank 8, through pump 10 and duct 11 , connecting it to distribution bar 12, located inside drum 2.
  • the latter is set in rotation about its axis via a motor 9, and it is then made to rotate at a pre-set speed, for a fast and even distribution of the liquid ammonia or liquid ammonia solution through the coils of the textile product 3 wound around drum 2.
  • the ammonia molecules are very small and thus can quickly and deeply penetrate the cellulosic structure of textile 3, causing the fibres to swell.
  • the rotational speed of drum 2 is determined so as to ensure perfect and even distribution of the liquid ammonia or liquid ammonia solution through the coiled textile, in order to guarantee thorough impregnation of all fibres and, finally, to control the amount of liquid ammonia or liquid ammonia solution which is to be left on the textile 3 (pick-up), in a range from 0.1 % to 200%.
  • This technical solution allows reducing the amount of ammonia or of liquid ammonia solution present inside vessel 1 and ensures a closer ratio of the liquid ammonia bath, or liquid ammonia solution bath, to the textile product 3.
  • the rotational speed of drum 2 will be high at the beginning of the centrifugal dispersion of the ammonia liquid through the coils of the textile, but it will decrease slowly until reaching the pre-set speed for a given pick-up.
  • the decrease of the rotational speed and of the relevant centrifugal force will ensure a gradual increase in ammonia pick-up, allowing even treatment across the entire textile product 3 wound around drum 2.
  • textile 3 is treated with liquid ammonia or with a liquid ammonia solution with a pre-selected pick-up and for a pre-set time period, varying from a few seconds to a few minutes.
  • the cycle can take place at the atmospheric pressure, or below or above it.
  • This process can undoubtedly be used to dye a textile product 3 by means of dyestuffs dissolved in liquid ammonia, said dyestuffs being quick-reaction ones, thanks to the high and even distribution of the bath through the wound-up textile.
  • the ammonia will then be evaporated and the dye will be fixed according to its recipe.
  • this process can be used to dye textile products previously impregnated, with a given pick-up, with liquid ammonia or with a liquid ammonia solution, by subsequent addition of a solution of chosen, compatible dyes.
  • the treatment with liquid ammonia or with a liquid ammonia solution will increase the volume of many textile fibres, resulting in improved penetration of the dye solution inside them.
  • the removal of liquid ammonia from the swollen fibres by means of an aqueous solution of compatible dyes will result in a markedly-oriented crystalline crosslinking of the cellulose fibres, whereby the final result will be an excellent colour yield.
  • the ammonia present in the new solution will then be evaporated and recovered, while the dyeing process will be completed according to its recipe.
  • impregnation of the textile 3 wound around drum 2 is accomplished by condensation of the ammonia or ammonia mixture from the gaseous to the liquid state, at a pressure above the atmospheric pressure.
  • condensation occurs at a pressure between 2 to 1 13 atmospheres and, preferably, between 5 to 40 atmospheres.
  • the table below shows the ammonia condensation temperatures at different pressures: 1 atm (atmospheric pressure) : - 33° C 4.4 atm : 0° C
  • the textile product 3, wound around drum 2, is cooled before the cycle starts (even down to temperatures well below 0°), through the effect of the vacuum created by pump 21 and by radiation-induced cooling provided by jacket 15 (whose function can also be performed by an appropriate heat exchanger), through which a cooling liquid can be passed.
  • the textile product 3 can be cooled by passing a flow of nitrogen through the coils.
  • cooling of the textile product 3 can be achieved by passing a flow of pressurised air through the coils, said air being cooled down, in turn, by contact with the walls of jacket 15, supplied internally with a cooling liquid. After cooling, all gas will be removed from the textile 3 by means of vacuum pump 21. Vessel 1 will then be brought to the same pressure as that of the outer tank containing the ammonia or ammonia solution, or to a pressure below such pressure, by means of appropriate adjustment valves, in the customary ways.
  • the difference between the temperature of the textile (say, 0° C) and the condensation temperature (say, 50° C at a pressure of 20 atm) will determine the impregnation of the textile product 3 by condensation of the ammonia or of the ammonia mixture from the gaseous to the liquid state. Changing the inlet pressure of the ammonia gas entering vessel 1 and the temperature of the textile, will cause the impregnation percentage of textile 3 to change accordingly.
  • Condensation under high pressure of the ammonia or ammonia mixture on the textile product 3 ensures a very fast, even and deep treatment of all fibres in the product wound around drum 2, as well as precise adjustment of the percentage of ammonia, or of liquid ammonia solution, which is to impregnate the entire textile product.
  • impregnation of the textile product 3, wound around drum 2 is accomplished in two subsequent steps.
  • First step partial impregnation of textile 3, with a pre-set pick-up, by condensation of ammonia or of an ammonia mixture from the gaseous to the liquid phase, at a pressure above the atmospheric one.
  • Second step complete impregnation of textile 3, with a pre-set pick-up, by mechanical centrifugal distribution of liquid ammonia or liquid ammonia solution through all the coils.
  • impregnation of the textile product 3, wound around drum 2 again takes place in two steps.
  • First step partial impregnation of textile 3, with a pre-set pick-up, by mechanical centrifugal distribution of liquid ammonia or liquid ammonia solution through all the coils.
  • Second step complete impregnation of textile 3, with a pre-set pick-up, by condensation of ammonia or of an ammonia mixture from the gaseous to the liquid phase, at a pressure above the atmospheric one. It is then necessary to remove the liquid ammonia or liquid ammonia solution, after chemical reaction with the fibre has occurred.
  • increasing the rotational speed of drum 2, up to some thousands of revolutions per minute increases the centrifugal acceleration imposed on the liquid ammonia, which has a low viscosity (approx. 25% as compared to the viscosity of water) and low surface tension (approx. 50% as compared to water), and so the liquid ammonia is extracted in the liquid state in very high percentages from textile 3.
  • vapours containing water and ammonia will be collected in a scrubber located outside the machine.
  • the final removal of ammonia can be achieved by washing with water in the liquid state at pre-set pressure and temperature.
  • the latter will be conveyed inside drum 2, kept in rotation, through duct 22, which conveys the water up to a bar 23, located inside drum 2, running along the entire length of the drum.
  • the water containing the ammonia traces will then be discharged from the vessel through the discharge device 24 and will then be conveyed to an appropriate support tank 1 ; such NH40H solution can then be treated inside a distillation tower, which will separate the aqueous part from the liquid ammonia, so that the latter can be re-used in the finishing treatment.
  • the liquid ammonia remaining on the textile product 3 after centrifugation will be removed by rinsing with water, whereby an ammonia hydroxide solution (NH4OH) will be formed, to which a diluted sodium hydrate (NaOH) solution will be added.
  • NH4OH ammonia hydroxide solution
  • NaOH sodium hydrate
  • a new balance will be created inside the solution, whereby a large amount of ammonia (NH3) in the gaseous form will be released; this, in turn, will be conveyed through duct 13 to condenser 4, where it will be converted into liquid ammonia, ready to be re-used.
  • the bath containing mainly sodium hydrate and the subsequent washings will then be discharged through the discharge device 24.
  • Vessel 1 can now be opened and, depending on the construction methods chosen, the drum can be unloaded from vessel 1 or, alternatively, the textile can be unwound from said vessel 1.
  • the device is now ready to start a new cycle, either by loading the drum 2 - with the textile product 3 wound around it - into vessel 1 , or by winding the textile product 3 around drum 2 while the latter is still inside vessel 1.
  • the choice of whether to leave the drum inside the vessel or to remove it and then fit it back in said vessel will be dictated by constructional and functional factors.
  • the textile product 3 treated with liquid ammonia or with a liquid ammonia solution, still wound around the drum 2, can then be dyed through the application of known dyeing recipes based on aqueous solutions; dyeing can be accomplished using dyestuffs in aqueous solutions, followed by washing.
  • the textile product 3, wound around drum 2 can be washed with water or steam (water vapour) at atmospheric pressure, or above it, prior to treatment with liquid ammonia or with a liquid ammonia solution. It also as obvious that the textile product 3, wound around drum 2, can be washed with a solvent such as perchloroethylene, trichloroethylene, freon or other solvents, prior to the treatment with liquid ammonia or with a liquid ammonia solution. In these cases, the machine needs to be completed with a supplementary circuit for washing with water/steam, or with a circuit for washing with solvents complete with distillation system, or with a circuit suitable for dyeing, followed by washing.
  • a solvent such as perchloroethylene, trichloroethylene, freon or other solvents
  • the textile product 3, still wound around drum 2 can be dried inside the machine, under pressure and at a temperature above 100° C, through the forced passage of air, or of another gas, heated by contact with the heat exchanger 15, supplied with a heating fluid.
  • the resulting vapours will be conveyed into exchanger 4, to be liquefied and then sent to an auxiliary tank. Drying under pressure, at a temperature above 100° C, confers excellent final dimensional stability to the textile product 3, especially in the case of cellulosic fibres previously treated with liquid ammonia.
  • machine 1 When not used for liquid ammonia treatments, machine 1 can be used for the known water/steam washing operations, for washing with solvent, carbonising, vaporization, dyeing, caustic soda treatment, setting, impregnation of textiles with chemical products, drying under pressure or for various combinations of the said operations.
  • process and relevant device described herein have been described purely by way of a non-limiting example.
  • ammonia removal systems need to be present (centrifugal action, heating, final removal of ammonia by steam or by water in the liquid state).
  • just one or two systems for the removal of liquid ammonia or liquid ammonia solution may be needed.
  • the discontinuous process referred to in this invention is capable to ensure a highly uniform treatment, through the use of liquid ammonia or of a liquid ammonia solution, and very high outputs.
  • the entire work cycle can be completed in a limited time of approximately 15 minutes.
  • the process referred to in this invention can be used to treat woven fabrics, non-woven fabrics, knitted fabrics, yarns, slivers and tow consisting of various types of different fibres, without resulting in unwanted shrinkage of the textile product 3.
  • the chemical product used in the process this can be, depending on the case, either 100% pure liquid ammonia, or a liquid ammonia solution, with an adjustable pick-up range of between 0.1 % to 200% relative to the weight of the textile product 3.
  • finishing treatments are examples of finishing treatments:
  • the treatment with liquid ammonia proved effective to improve the mechanical resistance of yarns, to increase weaving output as well as to ensure excellent wrinkle-free effect of the final clothes; pick-up 50%.
  • the treatment with liquid ammonia proved effective in order to improve the pilling resistance as well as the touch and dimensional stability of the fabric; pick-up 40%.
  • the treatment with an ammonia solution containing 15% water proved effective to ensure non-felting properties and permanent setting of the fibres.
  • the wool textile item was subjected to steaming at 120° C for two minutes; pick-up 100%.
  • the treatment with liquid ammonia proved effective to improve the look of the fabric, as well its final touch; pick-up 5%.
  • the treatment with liquid ammonia proved effective in order to achieve complete crosslinking of the resins; pick-up value of approx. 0.1 %.
  • a solution consisting of ammonia and selected dyes dissolved in it, or an ammonia solution with selected dyes and chemicals dissolved in it, or else a solution consisting of ammonia, water and dyes proved effective; varying pick-up value, up to 200%.
  • no ammonia leakage occurs, since vessel 1 is essentially a closed machine and a very safe one.
  • Said vessel 1 is also simple from a constructional viewpoint, as well as easy to manage and with very limited dimensions. In practice, vessel 1 will be capable of treating the textile product 3 at atmospheric pressure, or below or above the atmospheric pressure.
